Firstly, raw rubber was synthesized: methyl vinyl polysiloxane was polymerized by DMC, VMC and double-headed or hexamethylene head agent under the catalysis of alkaline rubber. The molecular weight of the polymer to be synthesized is determined according to the type of glue to be manufactured.
Secondly, the reinforcing filler and raw rubber are mixed evenly with a kneader. Then, other additives, such as vulcanizing agents, are added by rolling. Finally, filtering. This kind of glue is usually vulcanized by hot pressing.
