Embodiment Construction

[0013] see figure 1 and figure 2 , The adhesive tape 10 according to the first embodiment of the present invention includes a release protection layer 11 , an adhesive layer 13 provided on the release protection layer 11 , and a plurality of carrier particles 15 dispersed in the adhesive layer 13 . The peeling protective layer 11 is a release paper. The adhesive layer 13 is made of adhesive and is used for bonding objects (not shown). The carrying particle 15 is a hollow sphere, which includes an elastic closed shell 151 , and the shell 151 forms a buffer space 153 . The material of the shell 151 includes at least one of organic polymer materials, metals and ceramic materials, wherein, when organic polymer materials are used, the carrier particles 15 can be prepared from at least one of the following materials: vinylidene chloride-acrylonitrile Copolymer, polyvinyl alcohol, polyvinyl butyral, polymethyl methacrylate, polyacrylonitrile copolymer, polyvinylidene chloride and...

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.
