Problems solved by technology

[0005] Most of the existing automotive rubber adhesives use polysulfide rubber or solid rubber, such as neoprene, styrene-butadiene rubber, nitrile rubber, butyl rubber, etc., which have good shockproof effect, oil resistance and corrosion resistance, but solid rubber Type adhesives generally need to be produced in a kneader, and the production efficiency is low
Usually, the adhesive strength is not high enough, and the washing performance is poor, and it is easy to pollute the battery pool, which limits the application in high-strength structural bonding.
