ELASTIC ANTI-CORROSION ADHESIVE, ELASTIC ANTI-CORROSION ADHESIVE TAPE, AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2023/116465

A1

The present invention relates to the technical field of anti-corrosion adhesive tape materials. Disclosed are an elastic anti-corrosion adhesive, an elastic anti-corrosion adhesive tape, and a preparation method therefor. The elastic anti-corrosion adhesive comprises the following components in parts by weight: 5-8 parts of elastic rubber, 3-5 parts of high molecular weight polyisobutylene, 20-35 parts of medium molecular weight polyisobutylene, 5-10 parts of elastic fibers, 40-60 parts of inorganic powder, and 1-5 parts of an anti-aging agent. The elastic anti-corrosion adhesive of the present invention has excellent ductility and resilience; the ductility can enable the elastic anti-corrosion adhesive to be applied to a special-shaped part to form close bonding with the surface of a base material, thereby reducing hollowing; the resilience can enable the anti-corrosion adhesive to have self-tightening force, and promote the anti-corrosion adhesive to permeate into the microscopic surface of the base material, thereby thoroughly isolating air and moisture, and improving the anti-corrosion performance.
