Problems solved by technology

In practical applications, it is often encountered that nitrile rubber and natural rubber are bonded. Due to the large chemical structure difference between nitrile rubber and natural rubber, the bonding performance between the two rubbers is poor. A method to solve this problem The method is to paint the adhesive. At present, most of the adhesives sold on the market are expensive, and their use is limited.

Abstract

The invention relates to an adhesive. The adhesive comprises a rubber material and an organic solvent at a mass ratio of 1:3-20; the rubber material comprises or contains following ingredients, by weight, 40 to 60 parts of butadiene-acrylonitrile rubber, 20 to 50 parts of natural rubber, 10 to 30 parts of butadiene styrene rubber, 3 to 8 parts of zinc oxide, 0.5 to 2 parts of stearic acid, 1 to 3 parts of anti-aging agent RD, 5 to 10 parts of coumarone, 3 to 16 parts of 204 tackifying resin, 10 to 40 parts of carbon black N550, 5 to 15 parts of white carbon black, 2 to 8 parts of dioctyl phthalate, 1.0 to 3.5 parts of sulphur, 0.5 to 3 parts of accelerant CZ, 0.1 to 1 part of accelerant TMTD, and 0.5 to 3 parts of accelerant DM. A preparation method is simple; cost is low; and preparation is flexible.

Description

technical field [0001] The invention belongs to the technical field of adhesive formulations, in particular to an adhesive and a preparation method thereof. Background technique [0002] Nitrile rubber has excellent oil resistance and heat resistance. Natural rubber has the characteristics of high elasticity, high strength, good processability, and low heat generation. It is widely used in various fields of national economy. In practical applications, it is often encountered that nitrile rubber and natural rubber are bonded. Due to the large chemical structure difference between nitrile rubber and natural rubber, the bonding performance between the two rubbers is poor. A method to solve this problem The method is to apply the adhesive. At present, most of the adhesives sold on the market are expensive, and their use is limited. Contents of the invention [0003] The object of the present invention is to provide an adhesive to solve the above technical problems. [0004] ...
