Abstract

The invention discloses a strong glue for adhesive tapes. The strong glue comprises the following components by mass percentage: 60%-65% of silicon rubber, 15%-20% of a tackifier, 2%-5% of a crosslinking agent, 1%-5% of a curing agent, 5%-10% of a solvent, and 2%-7% of a catalyst. In this way, the glue provided by the invention can ensure good viscosity in a high temperature environment, good adhesion to a substrate, and high anti-stripping strength at the same time.

Description

technical field [0001] The invention relates to the field of adhesive tape materials, in particular to a superglue for adhesive tapes. Background technique [0002] Adhesive tape is made by coating the glue on the base material and processing it into a strip shape and supplying it as a reel. The glue layer on the tape should have high anti-peel strength, and the adhesive force between the adhesive and the base material should also be strong. The aluminum foil tape used to bond the condenser tube of the refrigerator to the inner liner of the refrigerator box is mainly a tape formed by coating the aluminum foil base layer with glue. This aluminum foil tape has high resistance to peeling strength and adhesion At the same time, because the condenser tube of the refrigerator will generate heat, there are also certain requirements for the adhesiveness of the adhesive layer at high temperatures. Existing glues used for adhesive tapes will lose their viscosity in high temperature e...
