Abstract

The present invention discloses an elastic anti-corrosion adhesive, an elastic anti-corrosion adhesive tape and a preparation method thereof, which belongs to the technical field of anti-corrosion adhesive tape materials, comprising: by weight, 5 to 8 parts of elastic rubber, 3 to 5 parts of high molecular weight polyisobutylene, 20 to 35 parts of medium molecular weight polyisobutylene, 5 to 10 parts of elastic fiber, 40 to 60 parts of inorganic powder and 1 to 5 parts of anti-aging agent. The elastic anti-corrosion adhesive provided by the present invention possesses excellent extensibility and resilience. The extensibility thereof allows it to be applied to irregular surfaces, forming a tight bond with the substrate surface, and reducing voids. And the resilience thereof gives the anti-corrosion adhesive self-tightening properties, promoting its penetration into the microscopic surface of the substrate, effectively isolating air and moisture, thereby enhancing its corrosion resistance.
