Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive, a preparation method and an application. Background technique [0002] With the rapid development of the rubber industry, rubber composite materials have been widely used. Rubber composite materials are compounded with various skeleton materials and added materials in rubber base materials to meet certain purposes or performance. In order to obtain high-performance rubber composites, in addition to selecting the appropriate skeleton material, the quality of the adhesive is also the key to the success of the rubber composite. Adhesives are used to keep the skeleton material and rubber as a whole when the product is used under harsh conditions, so as to better play the role of the skeleton material, so as to improve the quality of rubber products and prolong the service life of rubber products. [0003] With the increase in the types of rubber composite products and the expansion of ap...
