Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board on which a flat shape can be repeatedly positioned, mounted, or removed.

[0002]

BACKGROUND OF THE INVENTION A combination of a magnet and a metal has been known so far for a combination of a board and a flat shape that can be positioned on, mounted on or removed from the board. .
There are usually two examples in this regard. That is,
The board itself is magnetized and the flat shape is metal, and the board is metal and the flat shape is magnetized. The flat shape can be positioned freely on the board, but on the other hand,
It has a drawback that it easily slides on the substrate. That is, a flat object attached to the board may slide as the board is moved or moved. A further disadvantage to be pointed out in the case of such an embodiment is the relatively high manufacturing costs.

It is also known that such a combination consisting of a board and a flat shape is also possible by using a bonding technique. In this case, the flat shape is made of a very thin and extremely flexible flat material such as soft polyvinyl chloride (PVC). The board must also have a very flat surface. Adhesion occurs when a flat feature is positioned on the board. Since the thickness of the flat-shaped object is 100 to 200 μm, there is a drawback that it is difficult to peel the flat-shaped object in many cases. Furthermore, there are many prerequisites for adhering flat shaped objects to the flat surface of the board. Only special materials such as soft PVC, which is an extremely flexible material, can be used as flat shapes. The surface of the board must not be dusty or oily. Furthermore, the flat shape is at least partially peeled off the board, as the adhesion is often weaker over time. Since the adhesive force is also very small, the flat-shaped object may be easily peeled off due to mechanical influences during transportation. After all, flat features made of extremely thin materials are very difficult to handle, and therefore it is extremely difficult to move flat features on a base platform such as a flat table.

Further, it is known to use self-adhesive, removable and repositionable flats. Such a shape can be attached several times, which is a so-called sticker. However, the sticker has a problem that it gets dirty when it is repeatedly put on and taken off with fingers. The adhesive surface itself is very liable to be contaminated, for example, it is liable to be contaminated due to sweating action from human skin or adhesion of fat. Therefore, the adhesive force is lost after a certain period of time. As a result, the use of self-adhesive stickers that can be attached and removed is limited in terms of time of use. Furthermore, positioning such a sticker on the outside of the board is problematic and therefore impossible to move and position freely on a base base such as a table.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a board and a combination set composed of the board and a flat shape, and by using the combination set, the occurrence of the problems as described above. It is to prevent.

[0006]

In order to solve the above-mentioned problems, a board coated with a contact adhesive coating film that functions as a non-permanent self-adhesive attachment and detachment is provided. On the other hand, a non-self-adhesive flat shape is used. This means that the present invention provides a board on which non-self-adhesive flat shapes can be repeatedly positioned, mounted and removed, while at the same time the board is contact-bonded. It is meant to include a non-permanent self-adhesive substrate coated with the agent. Furthermore,
The non-permanent self-adhesive contact adhesive coating can be applied over the entire surface of the substrate or partially.

According to a preferred embodiment, the coating film of the non-permanent self-adhesive contact adhesive is composed of dome-shaped adhesive points applied in a raster shape (linear shape), and preferably, It is formed in a dot shape (a shape in which dots are in contact with each other) on the substrate, and its base is firmly connected to the substrate. By coating such a contact adhesive, on the one hand, excellent adhesion is created,
On the other hand, the non-self-adhesive flat features can be removed again at the same time without leaving any residue. That is, when the flat-shaped object is removed, the flat-shaped object can be peeled off without attaching any adhesive to the flat-shaped object.

In this case, it is particularly preferable to add a relay layer for adhesive force between the dome-shaped adhesive point and the substrate. For example, the adhesive relay layer may be made of rubber.

The generally spherical surface of the dome of the dome-shaped point of attachment faces the flat shape that is to be position-mounted, and thus relates to the adhesive properties that can be mounted and removed without leaving any residue. It becomes possible to provide the above-mentioned advantages under the adhesive technical conditions.

The application of dome-shaped adhesive spots on the substrate was obtained by the preferred embodiment of the invention in a gravure, flexographic or screen printing process. In particular, a rotating screen printing process is provided.

[0011]

Examples A useful example for the coating of contact adhesives is the use of hot melt adhesives, which
Not in a carrier system before coating. In other words, the hot melt adhesive is a carrier
Not in the system. That is, hot melt adhesives are used without a carrier system.
This is because hot melt adhesives do not disperse or emulsify and are therefore not used for dispersion, emulsification, coating in the form of organosols or plastisols.
However, the hot melt type adhesive may contain additives such as an adhesive resin, a softening agent, a viscosity reducing agent, a stabilizer, and a filler.

On the one hand, it can be removed without leaving any residue at all, and on the other hand, in order to obtain properties such that it has a particularly high adhesive strength, a hot-melt type adhesive of the above type is contact-bonded. Used as an agent to provide dome-shaped adhesion points in a raster on the substrate, and in this case
Keep the ratio of the dome-shaped adhesive point to the base surface diameter and its height between 5: 1 and 30: 1, preferably 10: 1.
It should be held between 25: 1. In this case, the diameter of the base surface of the dome-shaped adhesive point is preferably 80-
It is 500 μm, particularly preferably 100 to 400 μm. More preferably, the dome-shaped attachment points are provided in dots on the substrate.

The hot melt adhesive itself is preferably a thermoplastic (backbone) polymer such as natural rubber; SPS, SIS SEBS (styrene / ethylene / butadiene / styrene), SEPS (styrene / ethylene / propylene / styrene). ) (Triblock copolymer) and
Synthetic rubbers such as SB, SI and S-EP (diblock copolymer); polyolefins such as atactic polypropylene, ethylene-propylene-butadiene copolymer; polybutene acrylate, poly (2-ethylene-hexyl acrylate), polymethacrylate, and For example, acrylic acid, methacrylic acid, vinyl
Polyacrylate such as acetate, maleic anhydride, diacetone acryloamide or copolymer with acrylonitrile; ethylene-vinyl acetate copolymer, (1-vinyl-2-pyrrolidone) -vinyl
Polyvinyl derivatives such as acetate copolymer and vinyl acetate-vinyl lauriate copolymer; polyamide such as diethylene triamine polyamide; copolyamide; polyester; copolyester; copolyetherester; polyurethane and silicone. These backbone polymers can be used as copolymers or mixed with one another. In this case, the polymer can be completely crosslinked or can be postcrosslinked by irradiation with UV or ESH.

Suitable adhesive resins include, for example, aliphatic hydrocarbons, cycloaliphatic hydrocarbons and aromatic hydrocarbons; polyterenes; colophonium-glycerin esters, hydrogenated colophonium pentaerythrite esters, polymerized coforonium diethylene glycol esters, etc. Colophonium; and polymerized rosin.

Suitable softening agents include, for example, phthalates such as diethyl phthalate, dioctyl phthalate, di-isodecyl phthalate; phosphates such as tributyl phosphate, triphenyl phosphate; di-octyl radiparte; di-octyl sebacate; and di-butyl. There is male art.

Suitable viscosity reducing additives include, for example:
Aliphatic hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons; liquid polybutenes; liquid polystyrenes; xylene formaldehyde resins; coumarone indene resins and the like.

Suitable stabilizers are, for example, tetrakis [methylene-3- (3 ', 5'-di-tert-butyl-4'-hedoxyphenyl) -propinato] methane; 1,3,5-trimethyl -2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzol; 4,4'-thiobis- (6-tert-butyl-m-cresol); zinc-dibutyldi-
Thiocarbamide; octyl phenyl salicylate;
2-Hydroxy-4- (2-hydroxy-3-methacryloxy) propio-benzophenone; octadecyl-3-
(3 ', 5'-di-tert-butyl-butyl-4'-hydroxy-phenyl) propionate.

Suitable fillers are, for example, kaolin and mineral substances such as talc.

Preferred hot melt adhesives include:
It is preferable that the thermoplastic backbone polymer can be cross-linked by irradiation with, for example, ultraviolet rays (UV) or electron beams. Suitable thermoplastic backbone polymers include, for example, acrylates; polyester acrylates; and synthetic rubbers. The hot-melt adhesive crosslinked by irradiation need only be cured by irradiation after being applied on a flat shaped substrate. In contrast to hot-melt adhesives that are post-crosslinked, hot-melt adhesives that can be crosslinked by irradiation are characterized by a markedly higher stability at high temperatures. It is desirable that the hot-melt adhesive after irradiation cross-linking has a melting point of 120 to 150 ° C and a softening point of 50 to 180 ° C.

The viscosity of the hot melt adhesive is 100 to 160
It is desirable that it is about 1000 to 80,000 mPas in the processing temperature range of ° C.

The amount of adhesive applied is usually 3 to 15 g / m ² , preferably 6 to 10 g / m ² . In this case, the hot melt adhesive is preferably coated on the substrate so as to obtain a dot raster of 100 to 22500 dots / 625 mm ² , and particularly desirable is 1600 to 10000 dots / 62 mm.
The goal is to get a 5mm ^2- dot raster.

The surface coverage when using a hot melt adhesive is 10 to 85%, preferably 30 to 60%.

The substrate is preferably coated with a hot melt adhesive by a printing process such as a screen method, a gravure method or a flexographic method. In the case of the screen method, a flat screen or a round screen can be used. In the case of the flexographic method, the triple roller method is used, in which case the rollers are heated. However, it is also possible to use a doctor blade instead of the squeezing roller. The gravure method uses a doctor blade with a single screen and a cup roller system. In this case, the system used may be closed or open. Common to all these processes is that the substrate coated with hot melt adhesive is
rpressure) is provided between the roller and the printing body to which the adhesive is applied. The frequency and size of hot-melt adhesive dots can be determined directly by the variable separation print, or by the screen in the screen method, by the cup roller in the gravure method, or by the raster roller in the flexographic method. You can control.

The hot-melt adhesive is used in pure form and contains the abovementioned additives and can be postcrosslinked by irradiation with ultraviolet (UV) or electron beams.

The diameter-to-height ratio of the base surface of the dots of the hot-melt adhesive depends on the one hand on the structural viscosity, thixotropy and flowability of the hot-melt adhesive applied, and on the other hand. For example, when using a screen, it may be affected by the ratio of the aperture diameter of the screen used to the wall thickness.

Application of the hot melt adhesive is preferably carried out using a rotating screen printing unit. The ratio of the diameter of the base surface to the height of the dot is 85-170 μm wall thickness in the screen used in the rotary screen printing unit, and the transmittance of the hot-melt adhesive is about 10-45 μm. % When
It is an advantage of this method that it can be adjusted to particularly favorable conditions. Desirably, a screen of 1600-10000 aperture / 625 mm ² is used. Furthermore, favorable results are obtained when a screen is used in which the back pressure roller in the unit is equipped with a temperature control device.

The temperature required for the back pressure roller depends on the temperature and viscosity of the hot melt adhesive, and above all, the softening and melting points of the hot melt adhesive, the hot melt adhesive material It depends on the rate of formation on the screen and the bond strength. The desired values for softening point and melting point are
30-80 ° C and 80-250 ° C, respectively.

By using the above-mentioned parameters, the hot-melt adhesive can be applied on the substrate in a particularly preferred state. In this case, the ratio of the diameter of the base surface of the dot to the height of the dot is particularly adjustable.

Specific examples of hot melt adhesives and their application are disclosed in German patent application No. P 42 37 252.6.

According to another preferred embodiment of the invention, the coating of contact adhesive on the substrate is produced by high solids concentration adhesive dispersion. In this case, the variance is
It is an aqueous dispersion of an organosol or plastisol.
Especially desirable is thixotropic gel.
e) That is, an aqueous dispersion having a solid content of 55 to 65%.

Adhesive dispersions are also desirably produced with polymerized (meth) acrylates. In this case, the ester group is desirably an alkyl residue having 4 to 12 carbon atoms. If desired, monomers such as (meth) acrylic acid can be polymerized with (meth) acrylate.

The dispersions of the abovementioned high solids content adhesives are generally applied to a surface weight of 1 to ²⁰ g / m ² .

For the preferred adhesive dispersions used to coat the substrates of the present invention, see further DE-33 46 1
Explained by 00 Al. Also described therein is a method of dispersively applying such an adhesive by a gravure or flexographic or screen printing process, in particular rotating screen printing is desired and further The formation of the dome shape in the dispersion of the adhesive, the sizing of the dome and the rastering are also described.

Suitable materials for the substrate according to the present invention include fiber materials such as paper and board; synthetic fiber products; a mixture of synthetic fibers and natural fibers; and polyethylene (PE), polypropylene (PP). Oriented (OPP), polyester (PET), polystyrene (PS), polyamide (PA) or polyvinyl chloride (PV)
C) and other plastics such as composite materials
There is a foil. Furthermore, metals, metal compounds, metal alloys, and composite materials thereof can also be used as the substrate material. In this case, the material thickness is preferably 50 μm to 4 mm.

Here, when paper or paperboard is used as the substrate material, it may be coated or uncoated, and may be glossy or matte. Also, transparent foils may be laminated.

The substrate can be printed on one or both sides with the desired number of colors. In this case, as a printing method, a screen method, an offset method, a letterpress method, a flexographic method, and a gravure method are used in the methods of roll paper printing and cut sheet printing.

Further, in a particular embodiment, the substrate is composed of only one transparent, clear (non-printed) material. Particularly suitable for this purpose are very transparent photographic paper and PET, PE, PP, PA, PS, PV.
There are various plastic foils such as C. The desired thickness of the material in this case is between 50 μm and 3 mm, and in this embodiment the picture motif (picture
tive) can be removed.

In a further preferred embodiment of the substrate of the present invention, a self-adhesive substrate is used for non-self-adhesive coating in order to prevent dust, perspiration and perspiration and contamination by oily particles. Foil or non-self-adhesive paper is provided over this self-adhesive substrate. Suitable coating foils in this case include siliconized paper, synthetic fiber products, mixtures of synthetic and natural fibers and also various plastics such as PET, PE, PP, PA, PS, PVC. There are foils. If the adhesive force between the adhesive on the coating foil and the substrate is weakened, the coating foil will be easily peeled off from the adhesive film on the substrate. Controlled by adjusting. In order to be able to see the substrate motif and the flat features below it optimally, the coating foil must be a transparent and clear material, and therefore the substrate motif and the flat features. It is not necessary to remove the covering foil to see the motif of the object. The film thickness of the coating foil is preferably 50 to 500 μm, in which case the upper thickness region is desired. this is,
This is because a material having a certain value of rigidity and strength can be easily peeled from the surface of the self-adhesive substrate.

The coating foil is preferably attached to the top edge of the substrate or the left or right edge. It is desirable to use a permanently adhering adhesive strip to secure the coating foil to the substrate. In this case, the adhesive strip should be applied such that it does not tear the covering foil. In particular, tearing is likely to occur when pulling suddenly. Therefore, the adhesive strips are attached so as to frame the coating foil and the substrate at the top edge of the substrate and at the left or right edge so that the top side of the coating foil is directly connected to the back side of the substrate. It is desirable to do. In this way, the coating foil is
Even if it is pulled suddenly, it will not be torn. This is because the edging area functions as a kind of hinge. As an adhesive strip carrier,
PE, PP, PET or PVC based materials, paper or
Those composite materials can be used. The adhesive strip itself as an adhesive consists for example of a contact-type adhesive or adhesive which can be activated by heat and preferably has a width of 4 mm to 40 mm. In this case it is best to use clear and transparent adhesive strips.

The flat features to be positioned and fixed on the substrate usually have a thickness of 50 μm to 4 mm, and the coating foil is provided over this flat feature and the entire surface of the substrate. Therefore, since the height of the coating foil is different between the flat shape object and the substrate, the coating foil becomes wavy. In particular, when the flat shape has a small surface, the coating foil becomes particularly wavy. According to the preferred embodiment, such a phenomenon can be prevented by mounting the frame. The frame is attached to the edge of the substrate so that the edge is flush with the outer contour of the substrate. This frame can be made of fiber materials such as paper and paperboard, synthetic fiber products and blends of synthetic and natural fibers, as well as polyethylene (PE), polypropylene (PP) and polyester (PET).
), Polystyrene (PS), polyamide (PA) or,
It is composed of various plastic foils such as polyvinyl chloride (PVC) and their composite materials. Furthermore, metals, metal compounds, metal alloys, or composite materials thereof can also be used as the frame material.
The frame material may be printed, unprinted, or colored. As a printing method, a general offset method, flexographic method, letterpress method, gravure method, screen method or the like is used. The frame material typically has a thickness of 50 μm to 4 mm, preferably the thickness is the same as or greater than the thickness of the flat features. The width of the frame is preferably 1 to 20 mm.

In order to ensure a stable, removable and flat adhesive property of the coating foil on the frame, it is desirable to coat the frame with a non-permanent contact adhesive. This coating film can be formed by a printing process such as a screen method, a gravure method, or a flexographic method, as in the case of the substrate itself.

To secure the frame on the substrate, a permanent adhesive is applied to only the top side of the substrate in the region of the frame, or only to the back side of the frame, or both. It is hoped that this will be achieved.

In order to provide a board having improved strength, rigidity, and stability, a reinforcing material, that is, a stiffening material may be provided on the back side of the substrate. To this end, the back side of the substrate is self-adhesive, preferably permanently self-adhesive, to which a reinforcement is adhesively laminated or a non-self-adhesive type reinforcement is used. The substrate may be permanently adhered and fixed on the above. Suitable reinforcing materials in this case include fiber materials such as paper and paperboard, synthetic fiber products or mixtures of synthetic and natural fibers and PE, PP,
These include PA, PS, PVC, and various plastic foils composed of these composite materials. Further, as a material capable of improving stability, a metal, a metal compound, a metal alloy, or a composite material thereof may be used. In this case, the thickness of the material is usually 50 μm to 5 mm. The shape of the reinforcing material is preferably larger than the shape of the substrate.
The free surface left on the front side of the stiffener can be used to print information about the product, market name, etc. Instructions for use can be presented on the back side of the stiffener. The stiffener can be used to describe the board as well. A European standard Euro-perforation stamped on the free surface of the stiffener is used to suspend the board on a display stand.

A more specific embodiment of the board according to the invention comprises a substrate and, if rigidity is required, a non-permanent self-adhesive coating film provided on the substrate. Parking strip (parkin
g strip). The parking strip is located on the top or bottom edge of the board, either on or off the frame, or on the left or right edge, and serves to hold non-self-adhesive flat features. If the parking strip is outside the frame of the board, it preferably has its own frame of the same material, width and thickness as the board frame. This depends on its position, but it is desirable that the parking strip be the same length or width as the board or the reinforcement of the board and the other dimensions are wide or
It should be long. The substrate and contact adhesive coating of the parking strip are constructed and manufactured in the same manner as previously described for the board itself.

The invention will be explained in more detail below on the basis of specific embodiments with reference to the drawings.

As a result, the present invention includes a combination set consisting of a board of the type described above and a non-self-adhesive flat shape.

The outer shape and dimensions of the flat shape object are determined depending on the purpose of use of the board and the purpose of proposal. The shape of the flat shaped object is preferably formed by stamping or cutting, but otherwise it may be formed by manually crushing a stamped piece in advance.

Suitable materials for these flat shapes include cardboard and paperboard, synthetic fiber products and mixtures of synthetic and natural fibers, and various plastic foils such as PE, PP, PET, PS, PA and PVC. , There are these composite materials. Porous materials of all types made of plastic materials such as PE, natural rubber, cork, leather and synthetic leather or composites thereof are also possible materials for flat shapes. Further, a metal, a metal compound, a metal alloy, or a composite material thereof can be used as a material for the flat-shaped object. These materials usually have a thickness of 50 .mu.m to 4 mm, which may or may not be printed on one or both sides.
In this case, as a suitable printing method, an offset method, a screen method, a flexographic method, a gravure method, or the like can be used.

According to the present invention, a flat-shaped object on a board can be repeatedly attached, removed, or newly positioned as desired without leaving any residue. Further, the flat shape does not slip on the board when fixed on the board of the present invention. The back of a flat shape is not self-adhesive, so it can be removed from the board without leaving an adhesive residue, so the flat shape can be handled whenever needed, such as a table.

It can be used as a design board for construction of an exchange stand (assembly plate).

The subject of the present invention can also be used in the production of toys. In this case, the board represents the playing surface and the flat features represent the particular object or image. Therefore, by repeatedly positioning, attaching, and detaching the flat-shaped object, it is possible to display as many playing scenes as desired.

The details of the present invention will be described below with reference to specific examples.

Concrete example: Design board for interior decoration Coated on both sides, the dimensions are 152mm x 205m

A coating adhesive film is formed on the entire printed side surface of the substrate manufactured as described above by a rotary screen printing method. In this case, the substrate has a wall thickness of 130 μm, transmittance of 10%,
Aperture / 625 mm ² screen was used to coat the hot melt adhesive. The hot-melt adhesive used is PS 5002 from Novamelt Research GmbH (styrene / isoprene / styrene (SIS) -block copolymer, mixed with the adhesive in a 1: 1 ratio). The hot-melt adhesive had a melting point of 120 ° C and a viscosity of 49500 mPas at 150 ° C.
