Abstract
The invention discloses an adhesive tape comprising a stripping protective layer, an adhesive layer formed on the stripping protective layer and a plurality of bearing particles dispersed on the adhesive layer, wherein each bearing particle is a hollow elastic particle. According to the adhesive tape disclosed by the invention, the bearing particles are used as a base material layer, and the bearing particles are hollow elastic particles and can generate elastic deformation when being stressed, so that the bearing particles are not easily cracked, the stress of the adhesive tape is uniform, the impact resistance is improved, and furthermore, the adhering effect is improved. The glass transition temperatures of the bearing particles are relatively high, so that the whole temperature resistance of the adhesive tape can be improved, and furthermore, the shearing strength of the adhesive tape at high temperature is improved. In addition, the structure of the adhesive tape is relatively simple; and the preparation steps are also relatively simple, only the bearing particles are needed to be dispersed in an adhesive, and then, the stripping protective layer is coated by using the bearing particles. Moreover, the specific use demand of the adhesive tape can be conveniently met through designing the bearing particles.
Description
Technical field
The present invention relates to a kind of adhesive tape, particularly relate to a kind of double sticky tape.
Background technology
Double sticky tape general at present comprises substrate layer and is formed at two adhesive layers of substrate layer opposite flank respectively.Substrate layer is generally made up of foam.During use, by adhesive layer, thing to be bonded is bonded in together.The method of the foam of current formation substrate layer, control the expanding volume of swollen resin microballoon as adopted chemical process or adopt physical method to import in the material of main part of foam by bubble, the size of all more difficult control wherein bubble, even part bubble can break, unbalance stress when causing adhesive tape to use, more difficultly bears default loading.
Summary of the invention
In view of above content, the adhesive tape of uniform force when being necessary to provide a kind of use.
A kind of adhesive tape, it comprises the multiple carrying particles peeled off protective layer, be formed at the adhesive layer on stripping protective layer and be scattered in adhesive layer, and each carrying particle is for having elastic hollow granule.
Adhesive tape of the present invention adopts carrying particle to be used as substrate layer, and because carrying particle is for having elastic hollow ball, elastic deformation time stressed, not easily breaks, and makes adhesive tape uniform force, improves shock-resistance, thus improves bond effect.The glass transition temperature of carrying particle is higher, can improve the overall heat resistance of adhesive tape, thus shearing resistance when improving its high temperature.In addition, the structure of adhesive tape is simpler, and manufacturing step is simpler, only needs by carrying particle dispersion in tackiness agent, then, is coated on and peels off on protective layer, namely can be made into.Moreover, the specific user demand of adhesive tape is conveniently met by design carrying particle.

Main element nomenclature
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 and Fig. 2, the adhesive tape 10 of first embodiment of the invention comprises stripping protective layer 11, is arranged at the adhesive layer 13 peeled off on protective layer 11 and the multiple carrying particles 15 being scattered in adhesive layer 13.Peeling off protective layer 11 is separate-type paper.Adhesive layer 13 is made up of tackiness agent, for the object (not shown) that bonds.Carrying particle 15 is georama, and it comprises and has elastic closed housing 151, and housing 151 forms cushioning pocket 153.The material of housing 151 to comprise in organic polymer material, metal and stupalith at least one of them, wherein, when adopting organic polymer, carrying grain 15 can be prepared by following at least one kind of material: vinylidene chloride-acrylonitrile copolymer, polyvinyl alcohol, polyvinyl butyral acetal, polymethylmethacrylate, polyacrylonitrile copolymer, polyvinylidene dichloride and polysulfones; When adopting metal, carrying grain 15 can be prepared by following at least one kind of material: stainless steel, titanium, copper etc.; When adopting pottery, carrying grain 15 can be prepared by following at least one kind of material: the glass-ceramic of silicon-dioxide-organic high score mixing material and hollow.
In first embodiment of the invention, carrying particle 15 is made up of vinylidene chloride-acrylonitrile copolymer, and its particle diameter is roughly 1/4 of the thickness of adhesive layer 13, and adhesive layer 13 is roughly 0.6 kilograms per cubic meter with the global density of multiple carrying particle 15.The particle diameter of carrying particle 15 is not limited to the size of the first embodiment, and if the particle diameter carrying particle 15 is R, the thickness of adhesive layer 13 is D, as long as then meet 0.1D<R<0.9D; Adhesive layer 13 is not limited to the size of the first embodiment, as long as it is between 0.3 to 0.9 kilograms per cubic meter with the global density of multiple carrying particle 15.In first embodiment of the invention, multiple carrying particle 15 is dispersed in adhesive layer 13.
The adhesive tape 10 of first embodiment of the invention adopts carrying particle 15 to be used as substrate layer, because carrying particle 15 is for having elastic hollow ball, elastic deformation time stressed (please refer to the drawing 2), not easily break, can effective dissipation of ferees, make adhesive tape 10 uniform force, impact resistance is better, thus improves bond effect.The glass transition temperature of carrying particle 15 is higher, can improve the overall heat resistance of adhesive tape 10, thus shearing resistance when improving its high temperature.In addition, the structure of adhesive tape 10 is simpler, and manufacturing step is simpler, only needs carrying particle 15 to be scattered in tackiness agent, then, is coated on and peels off on protective layer 11, namely can be made into.Moreover, conveniently meeting the specific user demand design of adhesive tape 10 by design carrying particle 15, as made the shock-absorbing capacity of adhesive tape 10 better, then can make that the density of carrying particle 15 is lower or distribution density is larger; As made the water resistance of adhesive tape 10 better, then the housing 151 of carrying particle 155 can be made to be enclosed construction.
Refer to Fig. 3 and Fig. 4; the adhesive tape 20 of second embodiment of the invention and adhesive tape 10 similar of the first embodiment, adhesive tape 20 comprises stripping protective layer 21, is arranged at the adhesive layer 23 peeling off protective layer 21 and the multiple carrying particles 25 being scattered in adhesive layer 23.But carrying particle 25 is hollow ellipse ball, and its housing 251 offers multiple communicating aperture 250 be communicated with cushioning pocket 253, to increase its elasticity further.Please refer to the drawing 4, during use, as stressed in adhesive tape 20, there is deformation in carrying 25, particle.
Carrying particle 15,25 is not limited to above-mentioned shape, and it also can be Else Rule shape or irregularly shaped, as cube shaped, shape changeable etc.
Be appreciated that those skilled in the art also can do other change in spirit of the present invention, as long as it does not depart from technique effect of the present invention.These changes done according to the present invention's spirit, all should be included in the present invention's scope required for protection.
