Problems solved by technology

[0004] In some components, PC materials often require pressure-sensitive tape to fix or fix other materials or devices on the material; because PC materials are not stable in high-temperature and high-humidity environments, they are easy to hydrolyze and release carbon dioxide and water vapor. The tape is pasted on the surface of the PC material, and bubbles are prone to occur under high temperature and high humidity conditions, which will affect the bonding effect

Abstract

The invention relates to a high-performance environment-friendly adhesive which is an acrylate adhesive and consists of the following components in parts by mass: 1-8 parts of MMA (methl methacrylate), 5-93 parts of BA (butyl acrylate), 2-6 parts of AA (acrylic acid) and 1-5 parts of a crosslinking agent, wherein the acrylate adhesive is an acrylate polymer which is a polymer formed by a monomer with at least one acrylate group in one molecule as a main constitution monomer; and the weight average molecular weight (a) of the acrylate polymer is 30-80*10<4>. According to the high-performance environment-friendly adhesive provided by the invention, stirring is implemented while nitrogen is introduced into the solution of the acrylate polymer. By adopting the mode, oxygen in a polymerizationsystem can be removed, technical defects that carbon dioxide and moisture can be easily released through hydrolysis as a conventional PC material is poor in stability in a high temperature and high humidity environment can be solved, a prepared pressure sensitive adhesive tape is pasted to the surface of a PC material, a bubble phenomenon is barely caused under a high temperature and high humiditycondition, and a solid bonding effect can be maintained for a long time.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-performance environment-friendly adhesive and a preparation method thereof. Background technique [0002] Adhesive, also known as adhesive, referred to as glue (bonding agent, adhesive), is a non-metallic medium material that makes an object closely connected with another object. The adhesive only occupies a very thin layer of volume between the two adherend surfaces, but after the adhesive is used to complete the bonding construction, the obtained adhesive joints can meet various requirements of actual needs in terms of mechanical properties and physical and chemical properties. It can effectively bond materials together. [0003] PC is a thermoplastic engineering plastic with excellent comprehensive properties, which has high impact strength, transparency, rigidity, flame resistance, excellent electrical insulation and heat resistance. It has high dimensional stabili...
