Adhesive tape

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 [0001] The invention relates to an adhesive tape, in particular to a double-sided adhesive tape. Background technique [0002] The current general double-sided adhesive tape includes a substrate layer and two adhesive layers respectively formed on opposite sides of the substrate layer. The base layer is generally made of foam. When in use, the objects to be bonded can be bonded together through the adhesive layer. The current method of forming the foam of the substrate layer, such as using chemical methods to control the expansion volume of expanded resin microspheres or using physical methods to introduce air bubbles into the main material of the foam, is difficult to control the size of the air bubbles, and even some air bubbles will Cracks, resulting in uneven force on the tape during use, and it is difficult to bear the preset load. Contents of the invention [0003] In view of the above, it is necessary to provide an adhesive tape with uniform stres...
