Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to overcome the low bonding strength, complex composition of glue and high production cost of easy-pull removable adhesive tapes in the prior art. The risk of low stress will lead to easy delamination between the base material and the tape during stretch removal, and defects such as partial breakage that cannot be completely removed

Abstract

The invention discloses an easy-to-pull removable adhesive tape with a thermoplastic elastomer base material. The base material is a thermoplastic elastomer base material of styrene block copolymer, and the glue component and mass parts are: Body 80-150 parts, tackifying resin 75-130 parts, toluene 100-350 parts, color paste 5-15 parts. The thermoplastic elastomer base tape is a double-sided fixing tape with high bonding strength. It can be used after peeling off the release paper or release film during use. When it needs to be removed, just stretch the tape Instantly removable, making servicing and maintenance of electronic components quick and easy.

Description

technical field [0001] The invention belongs to the field of bonding and fixing tapes, and in particular relates to an easy-to-pull removable bonding and fixing tape with a thermoplastic elastomer base material. Background technique [0002] Adhesive tape products, as an indispensable daily necessities in modern society, play an important role in the fields of electronic products, handicrafts, metal, glass, toys and so on. Different types of adhesive tape products play different roles in the use of different industries. As we all know, adhesive tape products are becoming more and more popular in modern electronic products such as smartphones and tablet computers. However, during the use of many adhesive tape products, heavy work is required, and the product is only used as a temporary fix during product processing. At the same time, the staff is handling the product. When disassembly is required for after-sales maintenance or recycling, many electronic components are diffic...
