Description

technical field [0001] The invention relates to the technical field of processing aids for rubber products, in particular to a high-temperature and high-pressure resistant rubber tube middle rubber and inner rubber comprehensive accelerator and a preparation method thereof. Background technique [0002] Rubber accelerator refers to rubber vulcanization accelerator. Rubber vulcanization is mainly carried out with sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators came into being. Adding the accelerator to the rubber compound can promote the activation of the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and rubber molecules, and achieving the effect of shortening the vulcanization time and lowering the vulcanization temperature. According to the chemical structure, the vulcanization accelerators mainly used include sulfenamides, thiazoles, thiurams, and some guanidines, thioureas a...
