Abstract

PROBLEM TO BE SOLVED: To provide a work retainer material having superior freedom degree in attaching/detaching, moving after the retaining, and a retainer surface shape and having antipollution performance and to improve workability and machining precision by retaining a workpiece and a tool by the retainer material. SOLUTION: This working retainer material is silicone bouncing putty causing dilatancy phenomenon. The silicone bouncing putty 1 is projectingly fixed to a worktable 5 and, when the workpiece 2 hard to be retained is pushed thereagainst, the putty is fluidized and retained. When the workpiece with its pushed thereagainst is cut by a cutter 4a of the tool 4, the silicone bouncing putty 1 is turned into a hardened rubber state to the cutting operation. The silicone putty is provided with both of the liquid-phase and the solid-phase states so as to stably retain the workpiece at a superior freedom degree. It is beautifully released from the workpiece 2 just like a hardened silicone rubber. The deformation characteristics and adhesion characteristics of the putty are multifunctionally and efficiently used for various kinds of retainer tools such as a worktable, a surface plate, a retainer stand, a ruler, and gloves and chattering prevention.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work material, a tool and a stationery, and a work holding material for holding or stabilizing a work, a tool and a stationery in order to improve workability and working accuracy in a work of a hand working and a machining. The present invention relates to an application tool that can effectively use this holding material.

[0002]

2. Description of the Related Art Conventionally, it has been recognized from work experience that holding work pieces, tools, stationery, and tools have a great influence on work efficiency in manual and mechanical work. In order to improve this productivity, in the case of mass production, jigs and special fasteners are used. However, it is not suitable for high-mix low-volume production, on-site work, work such as personal hobby work, because the process is transient and the work holding part is diverse. In order to hold such work (fixing and preventing slippage), a holding means having excellent promptness and versatility is required. Further, this holding also greatly affects the processing accuracy.
In machining, the work is held firmly to prevent chattering errors.

Conventionally, the means for temporarily holding a work or the like in this temporary work is generally held by using an adhesive. This holding force is generated by the adhesive force of the adhesive. This is called a pressure-sensitive adhesive, and its form includes an adhesive tape composed of a support and an adhesive, a double-sided adhesive tape, and a clay-like adhesive composed of a shape-retaining agent and an adhesive. Most of the methods for holding a work piece are carried out by sandwiching and bonding the work piece and each flat surface of the installation surface with a double-sided adhesive tape. This tape-shaped adhesive agent is used by replacing it because the adhesive force is reduced when dust or the like adheres. In an actual work site, the holding function is lost after holding it about 5 times.

However, the pressure-sensitive adhesive and the clay-like pressure-sensitive adhesive have problems of peeling and destruction of the adherend mainly due to the pressure-sensitive adhesive force and contamination by the pressure-sensitive adhesive component. The adhesive strength is obtained by wetting due to the affinity of an adhesive polymer, a tackifier such as rosin, or a plasticizer. This affinity stickiness does not separate once wet. It feels sticky to the touch. This phenomenon is natural, and the adhesive acts as an adhesive by this action.
However, this is a problem in the proposed problem. For example,
When cutting a weak and weak material such as foil with a cutter, holding it with adhesive force makes the work easier. However, when removed after work, deformation or destruction due to adhesive force occurs,
This holding means is not suitable. Similarly, this phenomenon occurs with papers. This consideration is also necessary for holding complex and fragile objects such as insect specimens. Therefore, the film-shaped material is vacuum-adsorbed and held.

This phenomenon has a problem in the peeling property of the holding material. When the force required for peeling / tensile adhesive force (adhesive force) = peeling property, the smaller the peeling property is, the easier the holding material is to release. When the force required for peeling is determined by the peeling force in the direction of 90 degrees, the peeling property of the structural adhesive is 0.3 to 0.5. It is 0.01 for masking and protection tape. However, this protective tape is not stable in holding objects. A thermal release sheet has been proposed as a means for solving this problem. It is an adhesive sheet that can be easily peeled off by a means of softening the pressure-sensitive adhesive or a means of foaming the foaming agent in the pressure-sensitive adhesive by applying heat. This holding material ensures a sufficient holding force, and the peeling property can be 0.005 or less. However, the heat peeling means lacks convenience. In addition, a silicone resin may be polymer-alloyed as the main component of the pressure-sensitive adhesive to reduce the peeling property.

A clay-like pressure-sensitive adhesive is used as a material that facilitates this peeling due to its deformability. However, even with a clay-like adhesive,
Peel failure occurs in paper such as Japanese paper. Further, in the film, there is a defect that the components are transferred and the holding surface is contaminated. In the same manner, there are various clay-like compositions, but these compositions are more polluted and do not have tenacious holding power.
There is a means to prevent this sticky contamination by adding silicone. However, in this means, a releasing agent is applied between the holding material and the holding material, and this releasing property lowers the adhesive force and the holding ability becomes unstable.

Next, if the holding means is simply to prevent slippage, rubber or elastomer resin, which is a high friction material, is laid in a plate shape. As the rubber, natural and various synthetic rubbers are used. Examples of the elastomer resin include soft vinyl chloride resin, polyurethane resin, and acrylic resin. The composition that develops these holding powers has the same chemical structure as that of the pressure-sensitive adhesive, and can be made tacky and have high friction by preparation. This feature can be obtained by the difference in plasticity and cross-linking degree. For example, silicone adhesive and silicone rubber,
It is prepared and used like acrylic adhesive and soft acrylic resin, and polyurethane adhesive and soft polyurethane resin.

[0008] Next, there is a holding material that also holds and reinforces the workpiece. Since ancient times, natural thermoplastic resins such as pine resin and wax have been used for thin material processing such as engraving. in recent years,
There are chemically synthesized thermoplastic resins that show similar transformations. For example, polyethylene resins that are softened by boiling water are commercially available. The means utilizing this transformation is also used for fixing a semiconductor wafer. Further, a low fusion metal having a melting point of about 70 ° C. is also used as a reinforcing material. These are adhesive means that clearly use the wetting property in the liquid phase and the peeling property in the solid phase. When applied to an adhesive, it is a hot melt adhesive. However, it is not convenient due to the necessity of heat treatment or reaction treatment, and is not suitable for work in which the process is completed in a short time. In addition, there is a risk of burns due to heating, which is not suitable for manual work. This is a strong holding means for jig-like elements.

Next, the holding material may be used for the purpose of improving the processing quality. In the processing of the thin portion, the processing accuracy is reduced due to chatter and vibration. As one of the means for preventing this, there is a means for controlling chatter and vibration energy by sandwiching a holding material in the gap between the workpiece and the mounting base.
Japanese Patent Application Laid-Open No. 63-31001 for forming an oil film in a gap and Japanese Patent Application Laid-Open No. 07-001331 for a grinding method and a polishing apparatus for filling a rubber-like sealing agent having elasticity have been proposed. In addition, vibration prevention is performed with a granular material and a filling liquid.
There is a 0-237924 publication. These are techniques utilizing vibration damping by viscous materials. These techniques have been proposed because a sheet-shaped rubber material cannot cope with arbitrary gaps and holding portion shapes. Another problem with rubber materials is the problem of work piece deformation and rebound due to incompatibility. However, the liquid or sealing agent filling means needs to form the shape of the container into that structure, which is not convenient for a large number of small-volume prototypes.

[0010]

As described above, the relationship between the holding and the viscous material has a long history, and many holding materials and means have been tried. However, in addition to the above, the following operations and work holding are not possible or avoided at present.

In the work targeted by the present invention, the process changes to each process in a short time, and the situation changes. The holding (fixing) by the holding material in this situation ends its role in the next step. In order to deal with this, it is necessary to have a high degree of freedom in attachment and detachment. The first problem is the degree of freedom of attachment and detachment. The holding that constrains the degree of freedom like a conventional adhesive is not suitable. The reason for this is that the peeling property is large. In addition, the bonding means that uses the liquid phase and the solid phase separately makes the bonding process troublesome, and the degree of freedom of the subject cannot be obtained. If even weak objects are to be held, a tenacious holding force and a peeling property of 0.005 or less are required.

The second problem is the degree of freedom of movement after holding. For example, in the case of drawing a line on a standing wall with a long ruler, if the double-sided pressure-sensitive adhesive tape holds the ruler, it is not possible to make fine adjustments to fit the mark after fixing. This inconvenience of inflexible holding is often manual. This requires the ability to move in a held state. Even if this is solved by low cross-linking to form clay or gel, the accuracy cannot be secured due to the return due to elasticity. Clay-like adhesives correspond to this. Obtaining shape retention, deformability, non-migration property, and retention stability at the same time has not been solved by conventional viscous techniques.

The third issue is the degree of freedom of the shape of the holding surface. Sheets and tapes can only be used on smooth flat surfaces. On the other hand, clay-like pressure-sensitive adhesives and clay-like compositions having flexibility in shape have been investigated, but contamination of component transfer has not been solved by imparting deformability. Deformability without contamination is required.

The fourth problem is the non-contaminating property of the holding material. This is also a problem that occurs when trying to solve the second and third problems. This pollution problem has problems in normal time and deterioration. In normal times, the main problem is the influence on the subsequent process. This non-contamination level is, for example, an optical level high enough to hold a photographic negative film and not affect the printed image. At the time of deterioration, the problem is the ease of removing the deterioration component. If you continue to use the retainer in your work, you will eventually encounter a degraded retainer. In particular, high-performance adhesives such as polyurethane-based ones experience damage due to deterioration components.
The holding material needs a component structure that can be easily removed even if it is contaminated.

As described above, when a comprehensive function that is often present in manual work and the like is required, an optimum work holding material does not exist. The holding materials used in conventional holding technology have achieved high functionality and high quality for individual problems,
That is another drawback. This drawback causes inconvenience and a handling problem. Against this drawback,
The adjustment of the wetting property and the degree of cross-linking by the affinity has been the main solution means from the structure of the viscous material. However, the holding property and the peeling property, the deformability and the stain property, and the deformability and the holding property have a polar relationship, so that it is not an excellent work holding material.

In the conventional holding technique, a static fixing means is the main problem, and it is not possible to cope with the dynamic fixing. A holding material that solves this fixing cannot be obtained by the conventional viscous technique using a plasticizer or the like or structuring by crosslinking or the like. The present invention is
Provided is a clay-like work holding material and an application tool which solve these problems. Then, a work piece or the like which is impossible or shunned by the conventional holding material is held to improve workability and working accuracy.

[0017]

The present applicant has proposed Japanese Unexamined Patent Publication (Kokai) No. 8-247132 as a temporary fixing material for preventing a stationary object such as an ornament from falling and falling. This is a viscous material whose main component is silicone bouncing putty. It is a means to effectively develop the force of van der Waals, which is one of the adhesion theories, by utilizing the deformation characteristics to fix objects. Then, when peeled off, it can be removed cleanly by utilizing the release characteristics of cured silicone rubber. Unlike conventional fixing means mainly based on adhesion, it has an effect of not damaging both fixing. As a variety of accessories for furniture, it is a static fastening means intended for attachment using adhesive materials.

This means does not effectively utilize the tenacity fluidizing deformability due to boron and the quick mounting and dismounting obtained from the releasing property and non-migrating property. Moreover, the evaluation of this property and its application are not widely used in industry. In particular, non-migration and release properties have not been evaluated. INDUSTRIAL APPLICABILITY The present invention utilizes a fixing function excellent in this degree of freedom as a means for solving the conventional problems in a work holding material that holds a viscous material between a work piece and a tool to prevent movement. The main feature is that silicone bouncing putty is used as a work holding material. The silicone bouncing putty looks similar in appearance to conventional sticky materials. However, viscous means are different, and their handling and precautions are also different. The present invention provides an embodiment as a work holding material and its unique usage.

Next, there is provided a working holding material in which the boron-containing siloxane polymer or the boron-containing siloxane polymer mixture is made into a liquid state with a volatile non-aqueous or non-alcoholic solvent. A mixture containing a boron-containing siloxane polymer, which is the main component of the silicone bouncing putty, or a mixture containing the silicone bouncing putty is dissolved in the solvent to obtain a holding material. When this holding material is used, the solvent is volatilized to develop the holding function as putty or gel. It is used by infiltrating the bottom surface of a work piece or by applying it to the holding surface. This surface is not always a smooth plane. Especially, it is effective on uneven surfaces and textured surfaces.

Next, the main holding is carried out by clamps or screw fastening, but there are some workpieces in which the holding also causes a problem.
The representative is the occurrence of chatter. INDUSTRIAL APPLICABILITY The present invention relates to an anti-vibration material that sandwiches a viscous material with a processed material to suppress vibration, and is an anti-vibration material composed of silicone bouncing putty. The liquid one is an anti-chatter agent in which a boron-containing siloxane polymer or a boron-containing siloxane polymer mixture is made into a liquid state with a volatile non-aqueous or non-alcohol solvent.

Next, there is a work holder in which a silicone bouncing putty is housed in a bag having holes on the back and front. This means is a structure of a holder that prevents deterioration of putty due to chips and cutting oil generated during work. The putty that is exposed from the hole in the bag holds the work piece.

Next, a work table is provided with a recess on the work surface of the work table, and a silicone bouncing putty is embedded in the recess. The work table includes a table, a desk, and a surface plate used for work. This means uses a silicone bouncing putty to secure workpieces and tools to the workbench. This stabilizes the installation state of the processed objects and tools and improves workability.

Next, a work surface plate is provided with through holes on the surface plate surface, and the holes are filled with silicone bouncing putty.
The form of the work surface plate may be a rigid sheet to a plate or a trapezoid. This means uses a silicone bouncing putty to fix the work surface plate and workpieces and tools to the work table.

Next, there is a holding base having a silicone bouncing putty fixed to a support which can be fixed by other means. It can be fixed by other means that the support can be pressed with a finger, tightened with a screw, pinched with a tool, glued or the like.
A tool or a tool is moved or slid on the support in this state while being held by a silicone bouncing putty. Improves positioning accuracy by preventing shaking such as hand shaking and repulsion.

Next is a ruler having through holes corresponding to a diameter of 3 mm or more at both ends of the ruler. Generally, there is one hole for hanging purposes. If two pieces are provided, one at each end, a total of two rulers can be effectively used. The through hole is not limited to a circle.

Next is a glove or finger cot with a silicone bouncing putty fixed to a gripping portion for gripping an item of the glove or finger sack. Silicone bouncing putty prevents the gripping part that holds things such as fingertips from slipping and holds small parts firmly.

[0027]

Next, the operation of the present invention will be described. The silicone bouncing putty used in the present invention (hereinafter, silicone bouncing putty is referred to as putty) is a boron-containing siloxane obtained by binding boron to a part of a siloxane group, and a polymer composed of the boron-containing siloxane is an essential component. The polymer is made into a putty by adding a compounding agent such as a reinforcing material. FIG. 18 is a basic structural diagram of putty. As shown in the figure, in addition to the affinity action (wetting) for generating a cohesive force in the conventional clay-like composition, the oxygen atom 9b and the boron atom 9a of the boron-containing siloxane polymer 9 are added.
The cohesive force of the interaction with is added.

This interaction acts selectively only between the siloxane polymers and is stronger than the affinity. It behaves differently from conventional clay-like compositions of admixtures of non-boron-containing siloxane polymers (eg dimethyl silicone oils of organopolysiloxanes). Also, the structure is different from that of the silicone adhesive. FIG. 21 is a structural diagram of a conventional clay-like composition. As shown in the figure, the wetting of the polymer 10 and the plasticizer acts on the compounding agent and the like as cohesive energy, and the structure is constituted by the cohesive force. This wetting also acts on the contacted object in the same manner and causes contamination. If this wetting property is improved, in some cases, it becomes persistent pollution that is not cleaned up. A deteriorated polyurethane adhesive is an example of this, and is one of the problems to be solved.
This wetting is also one interaction, but the drawback is that this action works on all objects (objects held in this subject).

Next, FIG. 22 is a structural diagram of a conventional adhesive or gel. As shown, a portion of polymer 10 is crosslinked to provide shape retention strength. However, since this crosslinked structure limits the deformability, a liquid substance or a tackifier is put in the network structure to improve the wetting property. Besides, branch molecules improve wetting properties. In general, a structure in which an adhesive force is obtained by wetting the liquid substance or branch molecule and the adhesive layer is held by a crosslinked structure. Therefore, the deformability always includes rubber elasticity that depends on the degree of crosslinking. The clay-like pressure-sensitive adhesive is formed by blocking this, and is excellent in deformability, but rubber elasticity cannot be removed. This deformability including elasticity hinders the freedom of movement after holding.

On the other hand, this interaction is one of non-Newtonian viscosities (anomalous viscosities).
atancy) phenomenon is expressed. In this phenomenon, the apparent viscosity changes only by the deviation velocity. When the temperature and the atmospheric pressure are constant, the solid material becomes a solid at a high speed and becomes a fluid at a low speed due to the action speed of stress. Since the putty is a mixture containing a siloxane polymer as a main component, the putty becomes a cured silicone rubber state at a high speed, and the putty or paste state at a low speed. With regard to the physical properties, elasticity in a rubber state is exhibited at a high speed, and excellent ductility and viscosity without elasticity are exhibited at a low speed.

Since the interaction between the oxygen atom and the boron atom acts only between the siloxane polymers, this cohesive force acts as pseudo-crosslinking. As a result, a unique cross-linking action accompanied by deviation is exhibited. Thereby, even if it is a viscous substance, it is possible to obtain non-adhesive and non-migrating surface physical properties in the state of a silicone rubber that has undergone a curing reaction. On the contrary, even if it is a cured product, a deformation without elasticity is obtained from the deviation of the interaction. Peculiar thickening by boron is well known as a slimy viscous substance called slime, which is mainly composed of borax, polyvinyl alcohol and water. This feature is unique fluidization and non-stick surface properties. Boron is said to be necessary for this unique viscosity increase. As described above, the viscosification using boron can obtain unique physical properties that cannot be obtained by the conventional viscosification technology.

These phenomena appear in the human living environment (normal temperature, normal pressure, human operating speed). From this, the rubber state (solid phase) and the plastic state (liquid phase) can be utilized depending on the action speed. Further, the physical properties of both phases change in association with the action rate, and the solid phase and the liquid phase are simultaneously expressed for each action. By simply using this for adhesion,
There are extra characteristics. This transformation property can be applied as a tool or a functional material, which was not possible with conventional clay and sticky substances. A phenomenon very similar to this is the viscoelasticity found in concentrated solutions and melts of polymers. This requires high temperature, high pressure, high speed conditions outside the living environment,
It cannot be applied to humans.

The surface similar to that of the cured silicone rubber having no finger-tacking and migration property does not adhere only by touching. The peculiar adhesive force that generates the holding force is generated by the deformation of this surface. When a work is brought into contact with the putty and a little pressure is applied to it, a low-velocity stress acts and the putty deforms by dilatant flow. This deformation deforms like a liquid and comes into close contact with the micro uneven surface of the workpiece surface. Furthermore, when the linear siloxane polymer is arranged in microscopic unevenness, van der Waals force is generated, and the fixing force necessary for holding between both is developed. When this is generated instantly, it is the same as the liquid wetting. Due to its deformability, the low cross-linked gel comes into close contact with the micro uneven surface due to pressure sensitivity, but a slight elasticity separates the molecules, and only a fixing force sufficient for adhesion is obtained. The structure of the pressure-sensitive adhesive (pressure-sensitive adhesive) is also the same, and the main issue is to adjust the elasticity used for shape retention and the wetting property to cancel it.
The putty has excellent deformability that does not include elasticity, and can be wet.

Therefore, the holding force of the putty proceeds as shown in the relationship diagram between the contact time and the holding force in FIG. In the initial contact, even if pressure is applied, there is no adhesiveness, and in about 5 seconds, intimate contact due to deformation starts and the adhesive force begins to appear. Because of this delaying effect,
If you put putty on a person who does not know this physical property, it will not be recognized as an adhesive. The anti-slip effect is obtained at the same time as the contact. After that, it increases as shown in the figure and a fixing force of about the holding force is obtained. The beginning of this curve is due to the deformation properties, not the wetting properties of the components. In contrast, pressure-sensitive adhesives and clay-like compositions, which mainly utilize wetness, rapidly generate holding force. This rapid effect can be a drawback during work setup. The putty becomes stronger than the clay-like composition over time. This is because the structural cohesive force due to pseudo-crosslinking acts as a viscous strength. The previously proposed temporary fixing material is left for 30 minutes to 24 hours to generate an adhesive force equivalent to that of the pressure-sensitive adhesive and maintain the stationary state.

As described above, the holding force can be obtained by allowing the surface such as the cured silicone rubber having no finger touch to approach the surface of the workpiece or the like. When the linear polymer is dimethyl siloxane, the molecules are aligned on the micro surface in the glass or pottery, where the siloxane group side is closer to the silicon oxide on the surface, and the hydrocarbon group like polypropylene is closer to the methyl group side. The siloxane group or methyl group approaches the oxide film or hydroxyl group on the surface. With this arrangement, stable holding force can be obtained for various materials. This is the same as the state of being molded with silicone rubber. When releasing, the releasing characteristics of the cured silicone rubber can be utilized. When peeling force is applied from the end,
Leaves easily and cleanly like peeling the cured rubber. The tensile adhesive force (holding force) acts tenaciously due to the displacement deformation peculiar to putty. As a result, a peeling property of 0.005 or less is obtained, and the holding material has a high degree of freedom in attachment and detachment.

The thermoplastic adhesive is an adhesive means for selectively using the liquid phase and the solid phase by heat, and this means is an adhesive means for selectively using the liquid phase and the solid phase depending on the action speed. Then, the interaction between the boron atom and the oxygen atom, which is comparable to the cross-linking, shifts while acting, thereby enabling a tenacious deformation that does not include elasticity. This property gives the degree of freedom of movement after holding and the degree of freedom of the holding surface shape.

FIG. 20 is a conceptual diagram of contact of putty. The boron-containing siloxane polymer 9 which is the main component of the putty on the contacted surface has a cohesive force due to an affinity action (wetting) and an interaction between the oxygen atom 9b and the boron atom 9a acting on the putty main body, and has an affinity for the contacted surface. The adhesive force of the action acts. The energy of each force always increases by the amount of the interaction on the putty side, and the polymer transfers to the putty body side with a high probability. In this way, the interaction realizes the non-migrating property of the holding material, and by acting together with the releasability, the surface physical properties that are gentle to the contacted object are expressed. This action has a high non-staining property that does not affect the printed image even if the photographic negative film is retained. In the case of a mixture composed of a siloxane polymer containing no boron, which corresponds to a conventional clay-like composition, the migration side is not clear because it depends only on the affinity.
For this reason, they exhibit different behaviors in which releasability is obtained but migration of components cannot be prevented. As a matter of course, in the clay-like composition using oil or adhesive polymer as a plasticizer or binder, the components migrate further and contaminate the contact product. This holding material does not stain the work piece, hand or tool even if it is deformable. Conventionally possible holding means, which was possible with clay, but which has been shunned.

As described above, by containing boron, the putty exhibits unique viscosity and physical properties. The action of this viscous technique can solve the problems that have been problems with conventional adhesives and clay-like compositions. By effectively utilizing the action of the liquid phase and the solid phase, an excellent retention function and a new function can be utilized.

Next, putty is excellent in the effect of preventing cracks and its handling. At the interface with the workpiece, the vibration energy can be efficiently transmitted due to the approach of the molecules. With rubber materials, gaps occur and energy transfer is extremely poor. Pressing the gap causes a processing strain and is not suitable for a thin material which is likely to be cracked. Therefore, it has been a problem to effectively utilize the viscosity of the liquid phase. However, regarding the handling, in the liquid phase state, it is further fluidized by vibration and cannot be fixed at a predetermined position. In the solid state, a close contact state with good energy transfer cannot be obtained. As a means of utilizing the liquid phase and the solid phase, curing treatment is used. The damping mechanism of the elastic material and the soft material having a glass transition temperature or lower absorbs the vibration energy and converts it into heat energy for damping.

The anti-cracking material of the present invention differs greatly in the use and handling of the liquid phase and the solid phase. The physical properties of this putty for preventing cracks are, for example, K manufactured by Shin-Etsu Chemical Co., Ltd.
According to the manufacturer's data, the putty physical properties of E-SA-P are such that the elastic modulus is small due to stress action at a frequency of 0.1 Hz, and it is a liquid behavioral value. It becomes the numerical value shown. Repulsion rate when rigid body is 8
Indicates about 0. It can be used as a liquid when handled at a frequency of 1 Hz or less, and becomes a rubber filled with no gap at a vibration energy of 1 Hz or more. And, it acts as a liquid against displacement such as thermal expansion of 1 Hz or less. The sharing of the liquid phase and the solid phase provides the optimum physical properties as a crack preventing material.

Next, the boron-containing siloxane polymer mixture containing the boron-containing siloxane polymer or the putty can be analyzed based on the chemical structure of the linear siloxane to obtain the solubility parameter (SP).
It dissolves well in non-polar solvents with a small value). It also dissolves in polar solvents. In addition, the terminal hydroxyl group dissolves well in alcohols. Due to this hydroxyl group, the putty is not insoluble in water, which is a polar solvent, but hardly soluble. The holding material can be liquefied by utilizing this solubility. This holding agent becomes the original putty or gel when the solvent is volatilized, and acts like the putty. However, alcohol solvents are not preferable because they promote moisture absorption during volatilization and cause deterioration. This is because the physical properties may become unstable due to moisture absorption during long-term storage and volatilization. Therefore, it is used as a work holding agent and a chattering inhibitor by being made liquid with a volatile non-aqueous or non-alcoholic solvent. This composition is used by applying or penetrating into gaps and details that cannot be putty-like. The boron-containing siloxane polymer alone is susceptible to external water vapor, so that the usable time is limited. And it cannot be reused.

Next, the weather resistance of putty will be described. Viscous compositions always suffer from deterioration problems. Depending on the environment, putty has better weather resistance than conventional adhesives, but is more susceptible to the vapor of water and organic solvents. It absorbs these vapor molecules and weakens or eliminates the interaction between oxygen and boron atoms. As a result, the putty becomes a paste like car wax and becomes a normal clay composition. Putty and deteriorated paste-like putty are soluble in volatile silicones, alcohols, neutral detergents, and hot water, and are hardly soluble in water. Compared with general adhesive remover,
It is extremely safe. In the unlikely event that these deteriorated substances adhere, a safe removal measure that does not damage the contacted substances can be taken. The adhesive has a problem of solubility of the deteriorated product.

EXAMPLES Next, examples of the present invention will be described. The silicone bouncing putty is generally obtained by heat-reacting a boron compound with silicone oil or reactive silicone oil to form a boron-containing siloxane polymer, and adding a filler to obtain a putty substance. For detailed literature on this construction and manufacturing method, see, for example, Japanese Examined Patent Publication No. 266944/1994.
There is a -1227 publication. A dry silica fine powder or the like is added as a reinforcing agent to the boron-containing siloxane polymer obtained in the above production method example, and mixed with a kneader such as a kneader to prepare a putty composition. The reinforcing agent is 30 to 30 parts by weight based on 100 parts by weight of the boron-containing siloxane polymer from the feeling of use and weather resistance.
60 parts is preferred. Compounding agents for other purposes include inorganic oxide pigments such as titanium oxide and colored fine powders as colorants. Glycerin, high viscosity silicone oil,
Add a small amount of liquid paraffin. As a reinforcing agent against the cutting force, particles having a particle diameter of 1 to 3 mm such as metal or synthetic resin are mixed. Putty should be a stable composition containing no volatile components.

As a putty-like product, a dilatant compound manufactured by Dow Corning and a K manufactured by Shin-Etsu Chemical Co., Ltd.
E-SA-P is on the market. As the putty of this holding material, putty that is suitable for the environment of use will be adopted from manufactured or marketed products. The results of practical use on the marketed products show that the dilatant compound has a good response. In the present description, a specific use example of the putty as a work holding material will be described for a matter that is impossible or shunned by the conventional adhesive or clay-like composition.

The work-holding agent and anti-chattering agent prepared by liquidizing the boron-containing siloxane polymer or the boron-containing siloxane polymer mixture with a volatile non-aqueous or non-alcoholic solvent are the compositions to which the following solvents are added. . Specific examples of volatile solvents include volatile paraffin, benzene, toluene, xylene, methyl ethyl ketone, methyl acetate, ethyl acetate, hydrocarbon solvents such as industrial gasoline, and chlorinated solvents such as methylene chloride. Also, chlorinated solvents include substances that are subject to ozone layer protection and carcinogenesis, so their use must be avoided. Next, as the volatile silicone oil, dimethyl silicone oil having an oil concentration of 0.65 to 5 cSt can be adopted. Other examples include phenyl group-containing silicone oil and modified silicone oil. A liquid composition is prepared by adding a solvent to a putty-like product or a boron-containing siloxane polymer with these solvents. For example, in the putty, the softening starts gradually when 1 cSt of dimethyl silicone oil is added, and the volume ratio of the putty 10 increases.
It liquefies with about 70 parts of solvent to 0 part. Putty containing a thickener needs to be added further. Silicone oils or volatile paraffins are preferred as work-safe solvents.

FIG. 1 is a perspective view of a working mode using the work holding material of the present invention. Workpiece 2 is a model of a doll called a figure. The tool 4 is an electric tool and chucks the cutting tool of the carbide cutter 4a. The workbench 5 is an ordinary desk. In the work, burrs generated on the molded product are ground and removed by the cutter 4a. Unlike the geometrical processed object, the doll of the processed object 2 has many designed surfaces and no flat surface suitable for holding. Therefore, as a workability problem, it is difficult to stably hold. In addition, the structure is likely to be deformed or destroyed. And, there is painting in the subsequent process, and I do not want to adversely affect this. Conventionally, it is carried out by firmly grasping with a hand and laying a rubber plate or the like. The method of tightening and fixing with a vise is not adopted due to unstable holding and breakage of the work piece. Then, the tape-like pressure-sensitive adhesive obtains only an anti-slip effect, and the effect immediately disappears. Further, the clay-like pressure-sensitive adhesive has a bad influence on the coating in the subsequent step.

With this holding material, the putty 1 is placed on the workbench 5 to fix it, and the workpiece 2 is pressed onto this. Putty 1
Since the pressing action is slow, the curved surface of the workpiece 2 is faithfully transferred and brought into close contact with the deformation of the dilatancy phenomenon. Then, the force of Van der Waals acts for about 5 seconds to generate a holding force. This point is different from other holding materials. In this state it can still be easily released. The non-slip function of the work piece occurs instantly upon contact.

When the work 2 is cut by the cutter 4a in this holding state, the cutting action and vibration due to the working act at a high speed, so that the putty 1 becomes a cured rubber state against this action. This state is the same as that obtained by molding with silicone rubber, and is firmly held by the rubber rigidity and the shape effect of the curved surface of the workpiece 2. At the same time, the van der Waals force does not disappear and the putty 1 maintains the adhesiveness and the anti-slip effect. Further, in order to change the posture of the workpiece 2, it is possible to change the angle or move in this cutting state. The putty 1 is in a rubber state with respect to the cutting action, but is fluidly deformed with respect to a posture change that acts at a low speed. The degree of freedom of movement after the retention is obtained by a unique physical property in which the liquid phase and the solid phase coexist and can be used simultaneously and together. The workpiece 2 at the time of processing may be lightly gripped by using the moment with the holding portion as a fulcrum.

When the processing is completed, the workpiece 2 is lifted and easily separated. The holding material has van der Waals force and releasability that do not act excessively, and separates neatly like cured silicone rubber. The retained surface is paintable due to its non-migrating properties. Generally, silicone is shunned for coating, but putty 1 does not form a film as described in action. Therefore, the remaining silicone molecules act as a defoaming agent for the paint. Due to the processing, chips are accumulated on the putty 1. This cutting powder does not adhere to the putty 1 as long as it is not pressed because it does not have a finger-touch adhesion unlike an adhesive. This can be blown off or brushed off lightly. This work can be performed without contaminating the work piece, hands, or workbench. Store the used holding material for reuse. This holding material is provided as a product in which a block-shaped putty is contained in a container.

As described above, in the work of gripping and processing the work piece by hand, the workability is improved only by putting putty on the important points. In addition, it is suitable for holding bottles and pottery with many spherical shapes, holding wood rods when cutting wood rods with a saw, holding wood carvings by engraving, and holding die parts. For example, my hobby is egg art, where I work on eggshells and draw pictures. The object to be held is very fragile, and the holding surface is undefined. It can be used for such work that is difficult to hold. The width, thickness, and shape of the putty are determined by the size of the workpiece, the shape and material of the holding surface, the cutting force and type of processing, and an appropriate amount can be easily determined by trial. Thickness is 2
mm is standard.

The following is an embodiment of means for embedding and holding small parts in putty. FIG. 2 is a cross-sectional view holding small components. The small parts include precision small parts, optical parts, dentures, engravings, ornaments, coins and the like. These parts are subject to deformation and scratches and are too small to be gripped by hand. These are molded and held by a dedicated vise or silicone rubber. However, this means a large loss of work and material for one item. According to the present invention, as shown in the figure, the holding material 1 is filled and held except the processed surface 2a of the workpiece 2. The holding material 1 is in a cured rubber state against the cutting force at the time of processing, and is the same as the jig used for molding. The holding state is
The tenacious adhesive force acts on this and shows stability superior to that of the molding jig. Further, a jig needs to fix the jig, but this holding material also has this fixing function.

As a reinforcing agent against the cutting force of the holding material 1,
A polypropylene resin having a particle diameter of 2 mm was mixed as a reinforcing granule 1a by hand for reinforcement. This has little effect on the deformability during holding, and obtains a reinforcing effect during processing. When the processing is completed, the processed material 2 can be taken out cleanly by digging it from the holding material 1. Retaining materials should be stored and reused.
Besides small parts, it is suitable for holding net-like ornaments with complicated shapes. It is possible to maintain such a shape with general clay. However, only viscoelasticity can be used for the cutting force, and the clay is destroyed before the speed at which it can be effectively used, and the work piece is separated.

Next, an embodiment in which the tool is a ruler will be described. The ruler is a tool used for accurately drawing a target geometric line with a writing instrument or cutting with a cutter. A typical processed product in this example is paper,
Devices such as cloth, wallpaper, iron plate, glass, paintings, furniture, building materials, machines and automobiles. Paper that is not included in conventional adhesives,
Includes cloth and paintings. Tools are writing instruments such as pens and pencils, and blades such as cutters. This ruler is about 50 cm
If the length is longer than the above, it becomes difficult to hold both ends. In particular,
In the construction work, there are many works on the vertical wall, and the holding of the ruler becomes unstable.

FIG. 3 is a cross-sectional view in which the ruler is held by the holding material on the processed surface. FIG. 3A shows a state in which the putty 1 is crushed under the ruler 3 a and held on the processing surface 2.
(B) is a state in which the putty 1 is squeezed so as to protrude and is held on the processed surface 2. (C) is a state in which the putty 1 is pressed into a hole (a hole for hanging the ruler) existing in the ruler 3 a and held on the processed surface 2. This is a holding method using holes. Thus, it can be held with a simple structure. Such a holding form has already been proposed with a clay-like pressure-sensitive adhesive. This is an improvement plan to keep with clay. It is the same until it is sandwiched and held with a ruler, but in the pressure sensitive adhesive system, since the deformation includes elasticity, subsequent position adjustment is difficult. For this reason, it is not possible to exactly match the mark. This holding material can be finely adjusted by slowly moving it back and forth and left and right in the holding state. For example, when moved by 0.5 mm, it stops at that position and does not go back. With this accuracy, the difference between elastic deformation and shear deformation appears. For the action of external force after adjustment,
The rigidity can be developed and the holding can be maintained in a stable state. The putty has excellent deformability, and the thickness of the putty deforms to 1 mm or less without pressing it forcefully. The ruler can be separated after drawing. The holding material can be applied to the uneven surface of Japanese paper, cloth, and wallpaper. Fibers such as paper do not become entangled in the time it takes to draw a line.

A general ruler has one hole for the purpose of hanging. As another ruler of the present invention, if another hole is provided and held at both ends, it becomes a ruler with excellent convenience. FIG. 4 is a front view of a ruler having two holes. Diameter 3m at both ends of ruler 3a
A ruler having a through hole 3b corresponding to m or more was used. With a general ruler, one will be added. The through hole 3b is not limited to a circle, but an area that can be held is a necessary condition. Ruler 3a
Are held at both ends in the state of FIG. This ruler is a stationery that can effectively utilize this holding material. With this means, holding, adjustment, and drawing can be performed with only one hand, and a line can be drawn at an accurate position. The ruler holding means and this ruler
It is most suitable as a stationery material and a holding material to assist the writing of elderly people with disabilities and disabled people. In addition, one person can easily draw a line on a vertical wall during construction work.

The following is an example used for reproducing fragments.
Reproduction of the excavated product by the fragments excavated during the excavation and reproduction of the destroyed products by the fragments are repeated by trial and error like a jigsaw puzzle. Eventually, it is fixed with an adhesive, but until it is reproduced in that state, it is frequently attached and detached, such as being attached and detached, and keeping that state. This work requires flexibility in attachment and detachment. Moreover, the non-contaminating property of the holding material is also required. Unlike the stationary state fixing that has already been proposed, the holding surface is complicated and the putty is used three-dimensionally. Non-staining properties, unlike silicone clays, do not adversely affect post-process adhesion. Concrete work includes holding debris on the metalwork of pottery and forensic work in a traffic accident.

The following is an embodiment used for holding a minute component. When selecting minute parts (parts of rice grain size or less),
Parts may move due to wind and other problems. In addition, when designing minute parts such as beads and ornaments, they are handled by arranging them or replacing them. On the other hand, I want to work while holding the parts on the surface. This condition requires a holding means that easily separates the components and does not adversely affect the components or the work. For parts that are larger than rice grains, rolling objects such as pearls fall under this issue. The conventional means requires a certain degree of tackiness (adhesion to the touch with fingers). However, it is difficult to control this adhesive force.

FIG. 5 is a sectional view showing a state in which minute parts are placed. This putty 1 undergoes dilatancy deformation due to the slight self-weight of the minute component 2c, and the force of Van der Waals is automatically applied in close contact with the deformed surface to obtain an appropriate holding force. This holding force always provides a constant holding force due to its own weight. With the adhesive, the minute parts 2c are in point contact with each other, and a strong adhesive force that can be held at this point is obtained, or a pressing surface is obtained (pressure sensitive).
Let it hold. This holding force greatly varies depending on the conditions, and causes excessive holding or insufficient holding. As a result, breakage of the parts and defective holding occur. The present holding material can be laid in a sheet shape on a workbench or can be configured as a jig by covering a support with a sheet shape. It can also be laid on the bottom of the container to form a holding container. The peeling property of the present holding material can be selected, for example, by mixing the present putty and the granular sand and then taking out only the granular sand. In addition, this characteristic is 0.3
Even if the mm sharp core is fixed, it can be separated without breaking.

The following is an example of cutting a film or sheet that is flexible and has a weak stiffness. FIG. 6 is a cross-sectional view of holding and cutting the film. Put the putty 1 to a thickness of 1 to 3 mm on the surface of the work table 5 or the surface plate, and lightly press the film 2 of the workpiece on the surface. This pressing is not pressure-sensitive, but is a force for straightening wrinkles. Since the film surface is smooth, Van der Waals forces act in a short time. With this easy-to-separate adhesive force, the film
Can be fixed. In this state, the film 2 is cut by the cutter 4a of the tool. The blade of the cutter 4a cuts the film 2 and the putty 1 and fixes the cut product on the putty 1. At the time of cutting, there is no lateral displacement of the film 2, and a stable feeling of cutting the plate can be obtained. The cut product has a peeling property of the putty, and can be cleanly separated from the putty 1 without deformation. By applying this, skidding with a manual paper cutter can be prevented.

The present putty can hold the adhesive surface even if this film is an adhesive film. The putty comes into close contact with the surface of the adhesive layer to generate a holding force. The adhesive has releasability and does not adhere to silicone. However, the putty has excellent deformability, and this holding force is generated only by the action of van der Waals force due to the deformation of the putty. The holding force can be utilized for an appropriate degree of positioning. Further, since the non-transfer characteristic does not transfer to the surface of the adhesive layer, it does not adversely affect the subsequent adhesion. It can be used like a deformable release paper. 2. Description of the Related Art In recent years, electronic devices have often adopted a tacky adhesive structure. Assembling this adhesive sheet component is a difficult task because it adheres to other components.
It can be applied to hold this part temporarily. It can also be applied to various adhesive tape products.

In plate processing similar to this, there is a processing example in which a metal name plate Hatekin is used for marking. FIG. 7 is a cross-sectional view of a state in which a nameplate is stamped. When stamped on the steel plate of conventional means,
The nameplate is deformed and warped. When stamped on silicone rubber, rebound and deformation occur. This is due to the holding of the nameplate and the processing of stamping deformation. In the case of this holding material, the nameplate of the workpiece 2 is held by the adhesion characteristics of the putty 1 as shown in the figure, and the stamping deformation of the tool 4 by the takin causes the backside of the nameplate to be deformed with the same marking shape. Therefore, the warp of the nameplate is less likely to occur. In the case of local and sharp deformation such as engraving, a large stress that breaks the cured rubber is generated, and the putty 1 is plastically deformed. Therefore, the deformation of the nameplate due to the engraving does not cause warping by escaping to the back surface. In addition, the entire surface of the nameplate is adhered onto the silicone rubber, and this holding force also acts to prevent warpage. Besides, it can be applied to engraving of engraving.

The following is an example of transfer using carbon paper. FIG. 8 is a sectional view used for holding carbon transfer. In this work, the pattern drawn in the rough sketch is transferred to the work of the processed product 2 by the tool 3 made of carbon paper. Each sheet is easily moved because it is traced by the tool 4 such as a pen. For this reason, conventionally, each sheet is fixed with a tape, or is firmly held by hand to transfer. However, since the processed product 2 has many works such as paintings and crafts, it is required to be non-polluting and non-destructive. The present invention was used as a holding material for preventing the misalignment of the superposition. Put the putty 1 of rice grain size between the rough sketch and the carbon paper, and between the carbon paper and the processed material and press it. The putty 1 is crushed thinly to about 0.5 mm and holds each sheet. Adhesive causes peeling failure on paper, white wood, and white walls. Even if the putty 1 is pressed, it can be separated cleanly in about the time of the transfer work. Then, it is possible to correct the position after holding and repeatedly use it. It can be used with a feeling of peeling away like a cured silicone rubber.

The following is an example of a sensor which is frequently fixed temporarily in the measurement work. Ultrasonic sensors and temperature sensors are used for temperature measurement and flaw detection measurement. This sensor can reduce the measurement error by bringing the sensor into contact with the object to be measured as close as possible. And since this sensor part is the most important part, we want to avoid excessive load and cleaning. FIG. 9 is a cross-sectional view of the holding state of the sensor. (A) in the figure shows the holding state of the ultrasonic sensor. (B) is a holding state of the temperature sensor.

Conventionally, in ultrasonic measurement, a viscous substance that can be wiped is used to fill the gap. This viscous substance does not have a holding function, and it is necessary to constantly hold the ultrasonic sensor. This holding material cannot be left on a standing wall, but can be temporarily released. It can be released on a flat surface.
This makes the measuring task easier. As shown in the figure, if the sensor 4b is kept lightly pressed after the putty 1 is rolled and attached to the measurement surface 2b, the putty 1 can be brought into close contact with the gap by dilatancy deformation. This closeness is transformed like a fluid, and the measurement surface 2
Filling the fine irregularities of b, the thickness becomes 0.5 mm or less. At the same time, the force of Van der Waals acts and the holding power is obtained. The filled putty 1 becomes a rigid body for ultrasonic waves, and the sound waves are less attenuated. And the void-free filling transmits the sound waves accurately. The unevenness can be brought into contact with the sensor by softening the reinforcing agent to about 30 parts. Further, a holding material liquefied with a solvent can also be used. After measurement, it can be released like silicone rubber.

In the temperature sensor, the putty 1 is placed as shown in the figure, and the sensor 4b is held therein. Sensor 4
The force of van der Waals acts on b and the measuring surface 2b with excellent deformability to obtain a holding force. Since the putty 1 is attached to the putty 1 as closely as the molecules are attracted to each other, the conduction of temperature is superior to that of mere contact. For the temperature sensor, as a compounding agent for another purpose, fine metal powder such as aluminum or fine inorganic powder having excellent heat conduction is selected. Putty does not cause rashes or other injuries when used directly on the skin.
Further, even if the body is moved, the putty can be held in association with the movement of the skin. After measurement, it can be released like silicone rubber.

Next, if a holding material is used for the cutting work, chips and cutting oil generated during the work are mixed, and the putty is deteriorated or the chips are injured. As a means for preventing this, a putty is put in a bag and used as a working holder. Figure 10
It is sectional drawing hold | maintained by the work holding tool which put the putty in the bag. This working holder comprises a bag 7 made of low density polyethylene resin having holes on the back and front and a putty 1. Putty 1 was placed in this bag 7. The amount of putty 1 is about 50% of the inner volume of the bag. When the putty 1 in the bag 7 is deformed by this structure, the putty 1 is exposed through the holes on the back and front. This exposed surface is a means for holding between the workbench 5 and the workpiece 2. Chips and cutting oil generated during the work are blocked by the bag 7. In the figure, the blocks are raised to implement, but it is possible to implement without the blocks. This work holder is shown in FIG.
You can use it like a sheet even for work such as. This structure prevents undesired inclusion of foreign matter in the putty during holding. As the bag 7, various synthetic resin films can be adopted as long as it is flexible.

As described above, the holding material made of putty is often used by being attached to a support or a workbench. Next, it is an embodiment in which putty is applied to a workbench. FIG. 11 is a sectional view of the workbench. 5 mm deep on the work surface of the wooden work table 5
A recess 5a having a diameter of 20 mm was provided, and the putty 1 was embedded in the recess 5a. The inner surface of the recess 5a is surface-treated with a paint to prevent the polymer of the putty 1 from permeating. This treatment is unnecessary for non-penetrating surfaces. The workbench can be made of wood, metal, synthetic resin, porcelain, or the like. The embedded portion is made of a material or a treated surface that does not allow the polymer, which is a component of the putty 1, to permeate. However, among the metals, a metal having a catalytic action with the putty (copper has been confirmed) exerts a bad influence on the putty, and therefore a countermeasure is required. The work table includes a table used for work, a desk, a surface plate, a tilt table, and a column. Thus, by embedding the putty in the recess, a workbench having a holding function can be manufactured.

This means uses a putty 1 to place the work 2 on the workbench 5.
And fix the tools. This stabilizes the installation state of the workpiece 2 and tools and improves workability. The amount of putty 1 embedded in the recess 5 a is such that at least a part of the putty 1 can be exposed on the workbench 5. Depending on the surface shape of workpieces and tools, a larger amount than the volume of the recess 5a may be embedded. When not using this holding function, cover the sheet or film and use the workbench. By this treatment, the weather resistance of the putty 1 is improved. This workbench is suitable for holding and fixing the spherical side surface of a bottle when processing bottles. Specific examples include painting of vases, polishing of bottles, labeling of chemical bottles, and painting. Generally, the bottom of the bottle has a concave shape. For such bottom holding, an amount of putty that fits in this concave shape is additionally used. When the surface plate of the paper cutter is used as a work table, the cut film can be prevented from being displaced by providing the recess and embedding the putty. It is a cutter with excellent workability when cutting slippery films and paper.

Next, an example in which putty is applied to the work surface plate will be described. FIG. 12 is a cross-sectional view of the work surface plate. This is a work surface plate in which a through hole 6a is provided on the surface of the surface plate 6 and the putty 1 is filled in the hole portion. The form of the work surface plate may be a rigid sheet to a plate or a trapezoid. This means holds the work surface plate 6, the work piece 2 and tools on the work table 5 with the putty 1. By simply making a through hole in the conventional surface plate, it becomes a surface plate having a holding function. The same effect can be obtained even when the surface plate 6 is a work sheet. This work sheet can be used to fix a work piece on a desk. Like the work surface plate, the sheet has through holes 6
a is provided. The through holes are filled with the same amount of putty as the surface of the sheet or a small amount of putty. There is no limit on the thickness of the sheet,
A generally used one having a diameter of about 1 mm to 3 mm is preferable. When using the convex portion of the work piece, the thickness should be adapted accordingly.

FIG. 13 is a sectional view showing a thin work piece attached to a work surface plate. For the work, the plane processing surface 2a of the workpiece 2 is milled. Workpiece 2 is held by a clamp,
Chattering may occur during this processing. Therefore, the main holding is performed by a clamp, and the putty 1 is filled and sandwiched between the workpiece 2 and the surface plate. In this structure, when the putty 1 of a filling amount is placed under the processed surface 2a before clamping and the workpiece 2 is clamped by the clamp, the putty 1 is deformed and naturally enters this state. Simultaneously with the deformation, the force of Van der Waals acts closely on the surface of the work piece 2 to generate a holding force for adhesion. This deformation does not include elasticity, and repulsive deformation strain due to the holding force unlike the conventional rubber system does not occur. It is suitable for processing such as glass substrates where the flatness is important. If the gap is large, the holder contained in the bag of the present invention is used.

In this state, when the processed surface 2a is milled with an end mill, cutting vibration occurs. Chatter occurs when this vibration resonates with the vibration system of the workpiece 2. In this structure, the putty 1 mainly transmits the vibration energy and disperses it on the surface plate to prevent chattering. Since the attachment state of putty 1 is so close that the molecules are attracted to each other, energy is transferred more efficiently than simple contact. At the same time, the putty 1 becomes a rigid body against vibrations of 1 Hz or more, and firmly suppresses by the adhesive action of the force of Van der Waals. Since the rubber elasticity of the putty 1 is high, the vibration absorption rate is low. Unlike the conventional means for absorbing and attenuating vibrational energy, this chattering prevention is a means for efficiently transmitting and distributing energy to the outside. For this reason,
Means to prevent resonant systems act in a similar manner, but the effect applies to each frequency.

Vibration of each frequency is applied to the workpiece in this holding state. The change due to thermal expansion during processing is also one frequency, and the value is 0.001 Hz or less. This thermal stress becomes a large force and affects the flatness. With a clamping method that takes thermal stress into consideration, the putty deforms and absorbs this action. At this time, the putty does not leave following the movement. When a fine metal powder such as aluminum or an inorganic fine powder having excellent thermal conductivity is selected as a compounding agent for another purpose, the generated heat can be efficiently released. In this way, stable vibration prevention can be implemented. When there are few gaps, the boron-containing siloxane polymer is liquidized with a volatile solvent to prevent chatter. This means utilizes a liquid phase, but does not require a container structure such as a frame.

FIG. 14 is a cross-sectional view in which a preventive material is wrapped around to prevent chattering. In this work, the tip blade portion of the processed surface 2a of the ultrafine end mill, which is the workpiece 2, is ground and formed.
In order to prevent chattering, a putty 1 is wrapped around the workpiece 2 fixed (not rotated) to the chuck. With this structure, the putty 1 becomes a rigid body against the action of cutting vibration and is reinforced with silicone rubber. This reinforcement prevents resonance. As a means for further reinforcement, the outer circumference may be reinforced with a tubular body. With other workpieces, resonance can be prevented by placing the workpiece near the processing surface of the workpiece, filling the pipe or space, or the like. The mass of the putty 1 can be removed by releasing like a silicone rubber. And the non-polluting property can be easily used without soiling the hands and surroundings. This excellent workability can be easily applied to precision parts and parts having complicated shapes. Store the used holding material for reuse.

Next, an example of a holding table in which putty is fixed to a support is shown. As an example of this, a seal stamping operation will be described. FIG. 15 is a side view of the marking work using the holding table. As for the holding table, putty 1 having a weight of 1 g was fixed to a side surface of a wooden support body 8 having a size that can be pressed by a finger. To fix the putty 1, a cloth was adhered to the support 8 and entangled with the fibers. In this embodiment, the tool 3 is a seal.
This holding table is placed on the document to be imprinted, and the holding table and the document are fixed by pressing the document with a finger at a predetermined position. In this state, the side surface of the seal of the tool 3 is pressed against the putty 1. As shown in the figure, the putty 1 is deformed to hold the seal in a hollow state. When the seal stamp is moved downward in this held state, the putty 1 is displaced and deformed to slide the seal stamp. With the putty 1 held against shaking of the hand, the stamp surface can be smoothly pressed onto the document. Simultaneously with the imprinting, the finger of the support 8 is released to firmly imprint. Finally, the seal is separated from the putty 1 to complete the marking work.

Thus, the putty alone serves as a guide having a holding function. By using this holder, it is possible to imprint a clear imprint having no deviation at the target position. It is preferable that the surface of the holding table that comes into contact with the document is provided with a slip stopper such as rubber. The support can also be composed of a skeletal structure such as cardboard. Alternatively, it can be fixed by selecting an appropriate support (red meat or seal case) and using the adhesive force of the putty. By increasing the attachment area on the support side of the tool, the putty will be fixed to the support.
It is possible to move about 1 cm with 1 g of putty. Unlike conventional guides, the seal does not get dirty or scratched.
It can also be a guide for all surfaces such as circles and corners.

The holding table can be moved after being held due to the dilatancy phenomenon of putty. This freedom of movement is locked for fast stress action and movable for slow stress action. This action prevents shaking such as shaking and repulsion of the hand and improves positioning accuracy. FIG. 16 is a side view of the holding table for finely adjusting the movement of the tool. The support 8 is fastened and fixed to the surface plate with screws. The putty 1 is attached to the support 8 in this state and used as a holding material. The tool 4 or tool is attached to the putty 1 to support it, and the work is carried out by moving or sliding while holding it. When used for work under a microscope or work in which failure is not allowed, it improves the positioning accuracy. Tool 4
Corresponds to a pen, a needle, a cutting tool, a sensor, or the like. The support 8 can be fixed by other means such as sandwiching it with a tool or adhering it.

Next, there is a glove or a finger cot with a putty fixed to a gripping portion for gripping a glove or a finger sack. FIG. 17
FIG. 4 is a diagram of a glove in which a holding material is fixed to a grip portion. The putty 1 is fixed to a grip portion such as a fingertip of the glove 11 or the like to form the glove or finger sack of the present invention. For fixing, a fibrous material is entwined with the putty 1 to hold and form a layer. Items other than the entangled fibers retain the layer by the action of the putty 1.
If you are a work gloves, spread the putty thinly and press it, and the fibers will become entangled and settled. For rubber gloves, etc., when putty is thinly stretched and pressed, it is fixed by the adhesive action. The rubber puts off the putty cleanly, but it is sandwiched between the parts to be gripped to prevent slippage of both parts. As a result, the putty 1 of the grip portion functions as a holding material.

When gripped with the glove or finger cot of this construction, small parts such as screws, small piece plates, drills, and round bars can be firmly held. When gripping a plate-shaped object, you can prevent slipping and firmly hold it by simply fixing the putty of rice grain size. The grip portion generates a holding force due to adhesive friction and a shape effect only when a gripping force is applied. Unlike non-slip rubber, it can be held firmly as if it were gripped with an adhesive. The gripping part can be easily separated due to the release characteristics when the gripping force is omitted,
It feels like I'm holding it with my bare hands. The conventional pressure-sensitive adhesive adheres by the pressure-sensitive adhesive force even if the gripping force is omitted, and there is a risk that the pressure-sensitive adhesive may be caught together with the component. This glove can avoid this. The putty 1 attached to the fiber gloves or finger cot can be removed by a little careful washing with ordinary washing.

As described above, it can be said that the abnormal viscosity due to the interaction of boron was difficult with the conventional pressure-sensitive adhesive or clay-like composition. Further, by effectively utilizing the characteristics of silicone, it is possible to hold the film without any defects. The dilatant property of this putty includes more than just the fixing technology, and can be used in many ways by giving added value to the fixing. In addition, the movement characteristics that are particularly tenacious and have no elasticity can constitute a tool or tool that can effectively utilize the holding material according to the usage environment.

[0080]

As described above, the present invention has the following effects. (A) The peculiar viscosity of boron is a physical property of the surface of the cured silicone rubber, and a holding force is generated by the force of Van der Waals. This adhesion action provides a small peeling property, and can realize attachment / detachment with a high degree of freedom. This improvement overcomes the drawbacks of conventional tack retention. As a result, it can be applied to various work and many implementation environments, and expands the usage range of adhesive holding. (B) The dilatancy phenomenon, which is a characteristic of putty, enables fine adjustment after holding and movement in the holding state. And, by being able to share the action of the liquid phase and the solid phase after sandwiching,
Take advantage of good retention and new features. This degree of freedom provides a highly convenient holding material and improves workability. In addition, processing accuracy is improved by controlling various actions during processing. (C) The interaction of boron and the properties of silicone can realize optical level non-contamination. This high quality can be used in the processing of painted parts, optical parts, and precision parts, which have been shunned in the past, and avoid the risk of contamination. (D) Stiffening against the action of external force improves the stability and reliability of holding. For standing walls, unstable work, etc., you can prevent lateral slippage and support it lightly. (E) It is possible to hold a fibrous processed material such as paper and cloth, which has been difficult with the conventional adhesive type holding material. As a result, it can be used for papers and upholstered surfaces that are often used in stationery, creating new applications. (F) The clay form makes it possible to easily manufacture a tool having excellent holding properties.
