Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a rubber adhesive and a preparation method thereof. Background technique [0002] Rubber adhesive is a kind of adhesive formulated with synthetic rubber or natural rubber such as chloroprene, nitrile, butyl silicone rubber, polysulfide, etc. as the main material. It has excellent elasticity and is especially suitable for bonding soft or materials with different thermal expansion coefficients, such as the bonding between rubber and rubber, rubber and metal, plastic, leather, wood and other materials. One of the deficiencies in the prior art is that the thermodynamic properties of the rubber adhesive are not satisfactory and are not resistant to high temperatures. Contents of the invention [0003] The present invention aims to solve at least one of the above technical problems. [0004] For this reason, the first object of the present invention is to provide a kind of prepar...
