Problems solved by technology

[0004] However, at present, the market is mainly based on methyl-type silicone pressure-sensitive adhesives, which are mainly formed by the condensation reaction of methyl silicone rubber raw rubber and methyl MQ silicone resin. Can not meet the requirements of high and low temperature resistance
At the same time, most silicone pressure-sensitive adhesives are solvent-based, and they all use toxic solvents such as toluene or xylene as diluents. Whether they are produced or used by people, they will cause harm to the human body and pollute the air environment.

Abstract

The invention discloses an environmentally-friendly high-temperature-resistant special double-sided adhesive tape and a preparation method thereof. The special double-sided adhesive tape comprises a base material, pressure-sensitive adhesive layers located at two sides of the base material and release paper layers located at the outer sides of the pressure-sensitive adhesive layers at the two sides; and the raw material formula of every pressure-sensitive adhesive layer comprises, by mass, 60-90 parts of a monomer 2-ethylhexyl acrylate (EHA), 20-30 parts of a monomer butyl acrylate (BA), 6-10parts of a modified monomer maleimide resin, 26-39 parts of an initiator AIBN, 60-80 parts of a solvent and 9-13 parts of a curing agent. The special double-sided adhesive tape has the advantages of greenness, environmental friendliness, no pollution to the environment, high bonding strength, good resistance to weather, temperature and water, and good application prospect.

Description
