Problems solved by technology

However, the thickness of the flame-retardant easy-to-pull tape is relatively large, and when it is removed, there will be residual glue on the adherend, which will affect its performance
[0007] The easy-to-pull tapes in the prior art usually have problems in terms of tensile strength, adhesive performance and removal performance, and are easy to crack or be broken during use. At the same time, the adhesive strength is low, and it is difficult to ensure that the adherend can It is fixed stably and reliably, and there is a high risk of residual glue. When removing, there is residue between the adherends (such as batteries or motherboards), which affects the quality and efficiency of disassembly, and is not conducive to rework

Abstract

The invention provides an adhesive composition, an easy-to-pull adhesive tape as well as a preparation method and application of the easy-to-pull adhesive tape. The adhesive composition comprises thefollowing components in parts by weight: 50-80 parts of thermoplastic rubber and 30-70 parts of tackifying resin, wherein the tensile strength of the thermoplastic rubber is 20-40 MPa. The adhesive composition comprises specific thermoplastic rubber and tackifying resin, and the thermoplastic rubber and the tackifying resin cooperate with each other and are compounded, so that the adhesive composition is endowed with proper cohesion strength, relatively high tensile strength and bonding performance, and an adhered object is subjected to high-strength bonding and fixing in a direction perpendicular to a bonding surface; removing effect is good. The easy-to-pull adhesive tape containing the adhesive composition has excellent tensile resistance and bonding strength, can realize stable and reliable bonding between bonded objects, has good buffer effect and removal effect, has no residual adhesive on the bonded objects after removal, has good reworkability, the performance requirements of abattery assembly and an electronic product on an adhesive and an easy-to-pull adhesive tape are fully met.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an adhesive composition, an easy-to-pull adhesive tape, a preparation method and application thereof. Background technique [0002] With the rapid development of electronic technology and communication technology, electronic products such as smart phones and tablet computers have become an indispensable part of people's life and work. Electronic products usually use a fixed battery. In order to achieve safe and reliable fixing of the battery, the battery is usually fixed on the main board with an adhesive. However, the introduction of adhesives will make it difficult to disassemble the components of electronic products, and the residual adhesives will also be difficult to clean up, which brings operational inconvenience to product maintenance and battery recycling. [0003] In order to solve this difficulty, people have introduced easy-pull tapes in electronic prod...
