The invention utilises thermoexpanadable microspheres and thermal energy to debond interfaces in an adhesive system or as vehicle carriers. The invention also discloses a method of curing the adhesive system prior to the debonding step so that the same adhesive system may be used for both phases. The invention is especially useful in the automotive industry for end of vehicle life dismantling.
Description
The present invention relates to improve and adhere to or the system and the method on bonding two or more surfaces and peel off or the method and the device on the two or more surfaces of unsticking.Method and apparatus of the present invention especially but all be not used for automobile, aviation, navigation, finishing, packing and building industry is used for panel, framework, film, joint, metal sheet, glass port or other this needs are bonded together and/or the bonding and unsticking of the adhesive interface of isolating article; In some cases, unsticking system of the present invention and method can be applied to tackiness agent.The present invention also is applicable to dentistry and the surgery that needs filling of bonding tooth or osteoarthrosis to change.System of the present invention also can be used carrier or the conveying body of heat-expandable microsphere body and function work at other reagent of their expanding shell surface, thereby help other reagent in matrix or other systems, to disperse, comprise cleaned industry, perhaps they can be used for the multi-functional particle of dispersion/mixing and/or nano particle to avoid a bunch collection.
Background of invention
The known method that the car body parts are linked together of prior art for example links together them by riveted joint or spot welding and more recent laser.The recent trend of automotive industry is to use the modular structure of vehicle, thus with independent assembly connection/adhesion/bonding to form car body and relevant part.For two parts are tightly linked to each other, usually with arrangements for automotive doors or main body panel welding and/or be riveted together.Causus one or more interfaces with each part of fusion are used in welding, need be by professional's operation of understanding causus danger to self and auto parts.Causus face bend or the fusion that makes ground, need the cross section that higher technology is guaranteed to have only needs welding/partly/actual be heated with farthest reduce to the thermal damage of miscellaneous part may.In order to remove these riveted joint/welding assemblies, need strong physical strength.
The also known use binder composition of prior art is finished the fastening adhesion of two surface/grounds of vehicle part.Binder composition or glue have been widely used in by fastening windshield of one or two surface-coated tackiness agent and framework to parts, arrange make each surface bonding/link together.In order to promote or the speed adhesive solidification process that common described binder composition comprises solidifying agent.Described solidifying agent can be heat or humidity activated, is included in the composition to become solid form and therefore quicken the chemical adhesion process with crosslinked or polymeric liquid tackiness agent.In order to remove tackiness agent adherent parts, can use thermal mechanical strength and separate.For example, when adhesive/sealant hardens, windshield glass and framework be fastening bonding goes under the situation of position, removes windshield glass from framework and generally includes the vehicle glass rigger and use and comprise that round end (cheese) steel wire or special cutter cut/saw the hardened seal gum to remove windshield glass (normally complete form) along the periphery of windshield glass.This method needs powerful muscle power to separate the adhesive power of tackiness agent from structure, owing to sprain the disease that can cause rigger's muscle and bone aspect repeatedly.The other problems relevant with this method is that electric wire itself can break in addition because friction round end electric wire can be overheated.The weight of making great efforts farthest to reduce automobile to be to improve performance, to reduce oil consumption, use bonding other the trolley part (for example car door surface and framework) of tackiness agent to become the convention of automotive industry, so binder composition more and more widely is used for this technical field.In addition, along with carrying out new motor vehicle liquidation instruction (ELV), need to remove tackiness agent or unsticking in the automotive industry, so as fast, low-cost, safety and if possible removing and recycling auto parts (for example adherent glass port, panel etc.) with the method that re-uses.Therefore, need the unsticking of improvement to various surfaces.
The suitability for industrialized production several years also is used as the filler of polymkeric substance, paint, putty, plastisol, printing-ink and the filler that is used as paper, cardboard and explosive to the thermal expansion thermoplastic microspheres.WO 95/24441 has described the surrogate of the polyurethane foam that is used to fill automobile bodies part and sound damping binder composition form, and described surrogate comprises the alkane that the expanded microspheres of 5-15% is sealed.WO 00/75254 has also described tackiness agent and the tackiness agent primer composition that comprises the heat-expandable microsphere body, with the microcapsule heat-activated, produce pressure along the interface that scribbles said composition, this pressure has reduced the surperficial bonding and shearing or the tearing stress of jointing material.The chemistry on the interface of two adhesive surfaces and/or the reduction of physical adhesion are because the effect of expanded microspheres, can be described as therefore that non-sticking knot breaks and unsticking when expanded state the time.When using with the triggering thing that is fit to, the microsphere that exists at the interface has changed the structure of adhesive surface, unsticking immediately.The unsticking surface energy is than bonding energy of rupture low about 1/3rd.
A problem relevant with automotive industry be, when motor vehicle liquidation instruction (ELV), the most of trolley parts more than 85% must be removed and remove from automobile, but make safe disposal or with separately with the method recycling of special use.Because internals, dashboard, panel, car door surface, metal sheet, framework, lamp group and other this base parts need be separated from each other, it is time-consuming, harmful and expensive to health and environment to dispose automobile when scrapping.
The method and apparatus that non-toxic material and safety takes these parts apart that can (be preferably in several minutes) fast, effectively degrade is directly favourable to prior art, not only be used for automotive industry, also be used for any needs separately adhere to two surface/grounds of (being bonded together) by adhesive composition field, described adhesive composition can be present in the tackiness agent and/or primer and/or cleaning component of this system.
Estimate that method of the present invention can be used for the field of many different use microspheres, for example be not limited to cleaning and health, dentistry, surgical medicine, sports equipment production, furniture and application (particularly decorating wallpaper) and need separately other situations with upper surface.Microsphere volume increase after the expansion also can be used for helping transmission and dispersion to be deposited on its lip-deep reagent, causes the reagent that reduces relevant bunch collection phenomenon with functionally active with problem and the minimizing that alleviates bunch collection.
The invention statement
A first aspect of the present invention provides a kind of two or more surfaces or carrier or sticking method of pull-up with adhesive composition, described adhesive composition is included in the binder composition of its one or more adhesive surfaces, described composition places between described surface or carrier or the layer, described binder composition comprises its interface and wherein is dispersed with tackiness agent and/or the primer and/or the sanitising agent of heat-expandable microsphere body, for the described system of unsticking, the thermal radiation and/or the heat energy that concentrate on the enough energy levels on the described adhesive surface are provided, with the described microsphere that expands in described tackiness agent and/or primer and/or sanitising agent layer, cause the surface adhesion on the described interface of layer described in the described adhesive composition to weaken like this.
Preferably weakening bounding force on the interface of described layer does not cause and bondingly breaks or the matrix degraded the particularly poisonous degraded of matrix.
Preferred described method is solidified described binder composition before also being included in unsticking, the method that adopts is as follows: by thermal radiation and/or thermal conduction and/or the heat energy by certain energy level of described binder composition is provided, make the microsphere after the described expansion inclusion by they perforated shell leaching (leach) or migrate in the matrix of described composition.
Being preferred for the solidified microsphere is evenly distributed in the adhesive substrate.
The invention difference from existing technology is at the adhesive composition that comprises the heat-expandable microsphere body at sanitising agent and/or primer interface direct heating not, but microsphere self is accepted from the energy of the thermal radiation form in IR, UV source or electricity source and/or from treating the heat conducting energy in binding surface.Be surprised to find that because microsphere shows preferential absorption can expand under the temperature lower than composition temperature from thermal radiation and some microsphere of IR, need not to heat whole adhesive composition/composition.Found that some microsphere expansible temperature is than low about 40 ℃ of their institute's blended tackiness agent temperature when being exposed to IR energy following time.In this case, find unexpectedly for expanded microspheres need not the heated adhesive composition, but can heat microsphere self.Therefore, other advantages provided by the invention are farthest to reduce the consumption of energy and reduce the risk of destroying bonding ground.
Adhesive composition herein means and comprises binder composition, described binder composition comprises at least a tackiness agent, contains or does not contain primer and/or sanitising agent, solidifying agent, solvent or be used for finishing any other material that the form with layer or interlayer is bonded together one or more surfaces.Described binder composition embeds or supports microsphere, and under the sizable situation of the thickness of bonding coat and microsphere, the two sides of binder layer can be subjected to the influence of microsphere and trigger from the two sides.
Sanitising agent herein and/or primer mean and comprise that any surface treatment is to promote the bonding of tackiness agent and/or sealing agent.
The invention provides the method for the method and apparatus and the optional curing same combination of adhesive composition unsticking, wherein said system comprises the heat-expandable microsphere body that is scattered in the binder composition, and described composition places between two or more surfaces of described system.
In whole following specification sheets and claims, unless context has needs in addition, otherwise " comprising " or " containing " be interpreted as being meant and comprise described integral body (integar) or integrally combined, but do not get rid of any other integral body or integrally combined.
A second aspect of the present invention provides a kind of adhesive composition, described adhesive composition comprises curable adhesive composition and/or at the identical tackiness agent of its adhesive surface unsticking, described composition places between two or more surfaces of carrier or layer, and described binder composition comprises its interface and wherein is dispersed with tackiness agent and/or the primer and/or the sanitising agent of heat-expandable microsphere body, and described system may further comprise the steps:
(i) activation method of the described composition of curing, by thermal radiation and/or thermal conduction and/or the heat energy by first kind of energy level of described binder composition is provided, make the inclusion of the microsphere after the described expansion leach or migrate in the matrix of described composition by their perforated shell; With
(ii) thermal radiation by second kind of energy level is provided and/or heat energy are with the adhesive interface unsticking of the similar face of carrier or layer, described thermal radiation and/or centralized heat energy with the microsphere in expand described tackiness agent and/or primer and/or the sanitising agent layer, cause described in the described adhesive composition surface adhesion on the interface of layer to weaken in described adhesive surface like this.
Preferably in curing schedule, microsphere discharges its inclusion equably in adhesive substrate.
Therefore, method of the present invention can comprise two different stages or step, and this two different stages or step are still not controlled, and in fact carry out at two different time points.What will also be understood that is only to carry out separately a stage adhesive composition, that is to say can be only unsticking adhesive composition according to a first aspect of the invention, perhaps use same binder composition to solidify the system identical according to a second aspect of the invention with unsticking.
Be cured the stage subsequently or immediately after the binder composition deposit, the unsticking stage will carry out after a couple of days, several weeks, several months or several years after the curing usually.Consider this point, it is very important being used for solidified microballoon physical efficiency " dormancy " placement, that is to say at microsphere and inclusion is not leached " stock " state that is in composition substrate or before using; Need adopt heat energy to trigger the unsticking stage that microsphere just carries out sanitising agent and/or primer interface up to the user.
Fs or step are for solidifying.The heat-expandable microsphere body that is scattered in tackiness agent droplet matrix by the first kind produces curing.First kind microsphere has been sealed whipping agent and the solidifying agent that preferably mixes in its plastics or multipolymer housing, and can choose wantonly and also comprise catalyzer or activator.When enough thermal radiation and/or thermal conduction and/or heat energy and/or this first kind microsphere of electrical energy fed, solidifying agent is scattered in adhesive substrate, make to produce thermal expansion and the inclusion of microsphere leached, move, by, shift, discharge by or pass the hole of expansion housing.The inclusion of first kind heat-expandable microsphere body is released in the adhesive substrate under a certain specific temperature, and described specific temperature is usually less than the required temperature of the second class heat-expandable microsphere body that is used to finish the interface unsticking.The second class microsphere, i.e. those activatory microspheres under different temperature and the temperature that usually raises than first kind microsphere, preferred basic blend in the sanitising agent of binder composition and/or primer interface to promote the separation on surface.Perhaps, be used for unsticking microsphere can with the blend of tackiness agent own, particularly compare with the size of microsphere, when adhesive composition need hang down thickness or thin layer of adhesive composition, in this case, can trigger microspheres from two interfaces of described layer.
It should be understood that microsphere can be scattered in whole binder composition, maybe can be present in primer, clean layer or coat of painting, make that the surface tissue that has changed the material that is dispersed with microsphere produces unsticking effect fast when the heat supply expanded microspheres.
The present invention relates to provide the microsphere in one or two stage of the method that the energy of radiation and/or thermal conduction and/or electrically heated form heats first and second aspects of the present invention.Thermal conduction and the electrically heated of microsphere that is used for unsticking is by contacting with the surface of ground or supplying with by electric current or by the heat of binder composition or system.Be understood that and also can use microwave or ultrasonic wave to make thermal source.
In this manual, bondingly be meant adherent physical and chemical process in solidification process, particularly bonding by increase the extra increase in coarse or rough surface at interface zone in this manual, particularly pass through with original state and sanitising agent and/or primer blended unsticking heat-expandable microsphere body.Therefore, the present invention can not only advantageously improve solidified speed, also can strengthen the bond properties of composition at the interface.
Unsticking is suspended in the composition with microsphere, is positioned at or swims in topmost and have suitable size, and they deliberately produce the surface-area of coarse or rough increase, therefore provide higher machinery and stress intensity than the tackiness agent that does not have microsphere.
Unsticking is meant the destruction of chemical adhesion power on the physical damage of chemicals in adhesive composition and the interface.
The expansion of microsphere at the interface increased their volume, makes microsphere filledly in whole space surface and fill or occupy the surface of whole interface substantially, therefore destroyed the bounding force of interface or interfacial layer.
In this manual, solidification process is meant independent with bonding and unsticking process mentioned above of different process.The purpose of solidification process mainly is to give the chemical adhesion at binder composition physical construction intensity and interface, and it does not influence the volume of tackiness agent droplet, but influences the mechanical effect of droplet and chemical adhesion on the interface.
Preferably be used for the housing of sealing of solidified first kind microsphere, can will solidifying activator and foaming liquid and optional catalyst mix, making that when activating inclusion is by being immersed the perforated shell of the expanded microspheres that supports by expanding gas by heat energy.Under the situation of activator from the whipping agent that leaches, its solidification is different with subsequently the process that is uniformly distributed in adhesive substrate.At activator is under the situation of optical free radical or photoion, can be cured by the UV radiation, and therefore, activator leaches and helps uniform mixing in the substrate in this case.
Preferred swelling agent is selected from cocoa expanding gas, volatile reagent, distillation reagent, water, suction reagent or explosive agent.
But preferred adhesive be urethane, polyvinyl chloride, MS polymkeric substance, Resins, epoxy or any other suitable dispersion microsphere body and wish tackiness agent strengthen or solidify tackiness agent faster.Therefore, when microsphere was used for tooth, tackiness agent was the tooth filling mixt, and when microsphere was used for surgery, tackiness agent can be bone class tackiness agent.
The activation temperature of the first kind microsphere of preferred package envelope solidifying agent is different with the activation temperature of the second class microsphere, and the activation temperature of the preferred first kind is lower than the activation temperature of second class, and the temperature difference is between 20-100 ℃.
The activation temperature of the preferred unsticking or the second class microsphere is about 30-250 ℃, more preferably from about 110-200 ℃.The preferred second class microsphere seals swelling agent and diameter of section is littler than the diameter of section of first kind microsphere.
It should be understood that in a first aspect of the present invention, only need the second class microsphere and choose wantonly to comprise first kind microsphere, and in a second aspect of the present invention, described adhesive composition comprises two class microspheres.
In one embodiment of the invention, microsphere is used for cleaned industry, is particularly useful as the washing powder dispersing auxiliary, activation temperature be the said temperature scope than low side, probably in 30-80 ℃ of scope, this temperature and domestic hot water are suitable.
In another embodiment of the invention, microsphere is used for tooth fills, activation temperature in 40-70 ℃ of scope, the environment in this thermal adaptation oral cavity.
Depend on user's demand from the above-mentioned activation temperature that it should be understood that,, therefore will not limit the activation temperature scope of microsphere because the viscidity-removing method on the interface is essence of the present invention and optional curing in advance.
The housing of microsphere is made by the multipolymer of vinylformic acid and PMMA mixture usually, has therefore stoped them being lower than about 80 ℃ of possibilities of using down.Suggestion changes the composition of housing by adding plastics (for example polypropylene, PVC and/or polyethylene), and microsphere is inflatable and temperature is lower like this, thereby method of the present invention is used for tooth, medicine and cleaning (washing powder).
It should be understood that the enough temperature difference of needs when using microsphere to be used for the microsphere of cure adhesive and bonding/debonding interface, make and to finish two processes and can not intersect, therefore preferred different temperature range.What will also be understood that is, described composition also can comprise the heat-expandable microsphere body, described microsphere is sealed more than one different reagent or agent combination, and the expansion of each group or all kinds of microspheres can be different when being exposed to suitable temperature, make said composition can carry out the process of a series of regulations according to specific application temperature.Therefore, method of the present invention is equally applicable to for example need the adhesion of low-heat activatory wallpaper and separate, and needing perhaps to can be used for the bonding and unsticking of comparatively high temps activatory auto parts.
The first kind microsphere of preferred package envelope solidifying agent or other reagent is variable with the ratio of sealing the second class microsphere of detackifier, therefore the selection that is understood that described ratio can will not limit its scope according to user's the demand or the specific application of hope.
The preferred second class microsphere can scribble suitable black or dark-coloured material to increase blackness, therefore stops UV light to penetrate with the degraded tackiness agent, and in this embodiment, " triggering thing " will be the thermal source that IR or electricity produce.In one embodiment, when this method and composition is when being used for motor-vehicle glass window, in order further to reduce the degraded that penetrates and reduce tackiness agent of UV light, frit can apply the microsphere that scribbles dark-coloured material.
It should be understood that the microsphere that scribbles black material can reduce the blackness of windshield glass upper glass material, or can carry out stereosopic printing if desired.Because coating influences porosity, we find and must apply microsphere on suitable material.Therefore, when microsphere expands, influence the porosity of frit, and in fact produced stopping UV.By means of the hole expansible microsphere on spherical shell surface dispersing nanometer particle advantageously, therefore stop or farthest reduce bunch collection in the mixing process of the dispersion composite that comprises hardened plastic and solvent.Like this, evaporating solvent subsequently, microsphere as dispersion to avoid bunch collection of nano particle.
In this embodiment of the present invention, that is to say and use other reagent to apply the housing of microsphere that unexpanded microsphere can apply the reagent that the user needs.For example unexpanded microsphere can apply and for example be not limited to following material:
● treat to be used to improve the adherent monomer of polymeric matrix by UV radiation or other energy catalysis;
● improve its distribution and/or dispersive nano particle;
● can produce the molecule that stops, for example O in hertzian wave, chemical, the food packaging industry to following situation
2Degraded with prevent to degenerate too early, sound wave, heat or any other need produce the effect that stops.
Carry out on these surfaces that act on after the expansion, and the surface that is present in the only 1g microsphere in the matrix can be up to 10m
2Think that the present invention can be used for improvement and for example is not limited to the dispersion in solvent (for example water) of fragrance, fragrance and/or sanitising agent.The present invention also can be used for improving the transmission of medicine and other these class reagent.The present invention also can be used as the blocking layer to stop bunch collection of nano particle etc.In addition, the nanometer scavenging agent can be used as atmospheric blocking layer and the food spoilage of prevention in packing film or carton/carton.
In one embodiment of the invention, can apply suitable molecule on the surface of the housing of microsphere maybe can seal suitable molecule, make microsphere be used as " carrier " or " conveying body " to strengthen to carrying the effect of molecule, like this, described microsphere can improve the effect and the dispersion of the molecule that carries.In this embodiment, the design microsphere can use according to following principle:
● microsphere can be used as carrier to be dispersed in the molecule that carries on its coating, perhaps can be encapsulated as bigger molecule,
● microsphere can be used as chemistry or physical barriers layer,
● microsphere makes molecule evenly, simply and easier dispersion,
● when molecule during as the extremely thin film of expandable microspheres surface, photochemical catalysis is that effectively microsphere can be used as carrier in this case.
In a word, the housing of microsphere can apply or seal various materials and make that they are multi-functional and can be used for tackling many problems and can be used for many different fields.As previously mentioned, microsphere can apply or seal monomer and/or nano particle or washing composition or gold, and these materials can not be distributed in the surface of microsphere also for multi-functional under the expanded state.Utilize the variation of microsphere volume to make the surface become bigger up to more than 10 times, so the 1g microsphere can obtain the surface and is about 0.5m in the matrix than initial surface
2If, and use the microsphere of different swelling capacitys, for example volumetric expansion up to 100 times can obtain 6-10m
2The surface.In such embodiment, microsphere can be used for being dispersed in its lip-deep part material (for example monomer and/or nano particle).In fact, found can avoid a bunch collection when unexpanded or initial microsphere housing is loaded with the nano particle of diameter 20nm, still the distribution of the nano particle on surface of shell reaches 76% under expanded state.
Under this meaning, for reduce jitter time and on the microsphere surface after the expansion uniform distribution, microsphere makes the particle of coating be easy to disperse to remedy (salvage) attitude as carrier.Because thickness of shell reduces, but the lip-deep material of the microsphere after expansion is still identical, therefore can obtain to contain the surface in the identical life-span of identical particle.
Also can use microsphere, the sound wave of microballoon physical efficiency block electromagnetic radiation and the matrix by containing microsphere according to second important discovery.They also are used to the degraded that stops that atmosphere causes in food packaging industry.
Described microsphere also can be used for stoping bunch collection, that is to say the cohere that exists in cleaned industry problem together.
Preferably provide thermal radiation and/or thermal conduction or electric energy for microsphere: electromagnetic wave source (for example IR or UV radiation), convection oven, method for electrically (for example battery or laser), ultrasonic wave, gas or air or white light by following mode.
Using adhesive composition to do under the situation of decorative paper backing, can finish unsticking by for example family expenses flatiron or blower.
It should be understood that IR is the hertzian wave that only just can become heat when being absorbed by the object with some characteristic of its directive.Therefore only when the IR light beam is absorbed by object, the system of use IR just becomes " heat " system.Therefore, become thermal radiation and thermal conduction, the IR radiation is become thermal source up to 3000-7000nm by IR hertzian wave with 800-2600nm.In the present invention, the heat-expandable microsphere body mainly passes through IR or UV and/or thermal radiation heating, and does not use thermal conduction (for example from metal sheet) heating.
When using the IR radiation spectrum to make the energy, the form of supply is one or more lamps or is the form of optical fiber, optical wand or plate.The IR radiation is converted into the thermal radiation of the internal surface (for example internal surface of panel) at hot face, depends on the temperature that the panel exposed surface reaches to a great extent.The T of surface panel is depended in energy thermal radiation (power thermal radiation)
4(T exp4), this is worth not in the IR in lamp source radiating low side scope, but in the hot IR radiation scope of about 3000-7000nm.It should be understood that by conduction heating and depend on many factors, for example the composition of the thermal conductivity of surface or panel material, sanitising agent-primer (cleaner-primer) and binder layer.
Using electrically heated to do under the situation of thermal source expanded microspheres, can pass panel by electric current and carry out electrically heated, panel at this moment is a resistance.In one embodiment of the invention, aluminium, steel wire/silk/rope, microfilament, carbon primitive fiber or other conducting fibres (for example scribbling the glass fibre of metal) are embedded in the binder composition, particularly at the interface of tackiness agent to produce Faraday's cage.Microfilament is scattered in the Polygons that produces entanglement or electrical conductor in the tackiness agent and arranges.This entanglement forms numerous little electricity rings around the swelling property microsphere on three-dimensional, the swelling property microsphere can cause expansion when a certain top temperature.This phenomenon is called electric current tunnel (tunnelling).
Preferred microfilament or fiber mix with tackiness agent, and can be about 100 μ m length and diameter is 2-20 μ m.In one embodiment, carbon fiber can be diameter and the 50-100 μ m length of 5-10 μ m.We think that in order to produce the tunnel, composition should comprise the microfilament of about 0.5-10% volume under the perfect condition, more preferably from about the 1-3% volume.It should be understood that in the composition percent by volume of microsphere influences the number of the point of contact of mutual bridge joint, can select the percent by volume of microsphere according to user's demand.
Preferred heat-expandable microsphere body supply form maybe can be attached to line, silk or fiber for embedding or being coated on band, sieve or the film, perhaps can be attached to one or two contact surface of wishing curing and/or separating component.First kind microsphere can be.Preferred solidifying agent or the activator that discharges is uniformly distributed in adhesive substrate, makes available self energy system (for example UV of polymerization and/or crosslinked or optical free radical and/or photoion activation) activation.
Therefore, the invention provides compared with prior art unique method, this method is used for linking to each other of plastics-plastics, plastic-metal, metal-metal, ceramic-metal, aluminium-aluminium, aluminium-plastics, matrix material-metal, matrix material-plastics, matrix material-pottery, paper-wall, tooth filling-tooth, artificial joint-bone and similar surfaces, owing to directly do not trigger composition, but pass through the thermal radiation and/or the thermal conduction heating combination of contact surface or its lower surface with the IR or the UV light that for example penetrate one of sandwich panel.
Preferred described method comprises above described any or multifrequency nature.
Particularly find by experiment, for IR is absorbed by whipping agent and composition thereof, the parameter of used IR lamp (for example energy and the spectrum of reflection, light beam) must be adapted at embedding the preceding or temperature expansion microsphere before microsphere embeds the adhesive composition degraded at primer and/or sanitising agent interface of matrix degraded of microsphere.Like this, because the degraded of tackiness agent even use the PU tackiness agent, preferably avoids using toxic reagent.
The separately method on two surfaces that have been bonded together that provides on the one hand more of the present invention, described method comprises to the surface that scribbles or be stained with composition mentioned above on it provides enough thermal radiation and/or thermal conduction, and the heat energy of supplying with one or two contact surface of the article for the treatment of separate/makes a part of heat-expandable microsphere body discharge swelling agent in composition.
Preferred described method comprises above described any or various features.
Obviously, can avoid chemical interaction in the present invention, method of the present invention depends on the physical engineering technology and carries out and promote curing system, described curing system need the adhesion stage process need sometime by the mixing cured activator of uniform distribution, and preferably also can distinguish suitably blended zone of heat-expandable microsphere body.In principle, the heat-expandable microsphere body and function is made the small container of neutrality or inertia curing activator, break or the volume increase up to a certain moment, housing begins to leach gaseous state or liquid activator as porous wall, makes activator to diffuse to adhesive substrate equably by the transmission of foaming agent gas.
Can activate different activators by different temperature-activated heat-expandable microsphere bodies, like this, can finish the curing of binder composition in the different steps of this method in different zones, in addition, use with specific requirement under operate, make that whole process is more controlled and have multifunctionality.
The present invention has advantageously provided controlled solidification process, and wherein solidification process does not rely on chemical reaction, and for example polymerization, crosslinked, crystallization, gelling or any other phase change.
