Abstract

The invention discloses a rubber comprehensive accelerator and a method for preparing the same.The rubber comprehensive accelerator mainly comprises, by weight, 40-75 parts of high-activity zinc oxide, 2-9 parts of after-effectiveness sulfenamide accelerators, 7-15 parts of thiazole accelerators, 10-21 parts of ultrahigh-speed accelerators and 8-19 parts of macromolecular carriers.The rubber comprehensive accelerator and the method have the advantages that different types of additives can be sufficiently mixed with one another by the aid of a step-by-step adding process, accordingly, the rubber comprehensive accelerator is excellent in aging resistance and yellowing resistance, and mechanical properties of rubber products further can be improved.

Description

technical field

[0001] The invention relates to the field of rubber industry, more specifically, it relates to a comprehensive rubber accelerator and a preparation method thereof. Background technique

[0002] Rubber accelerator is also called rubber vulcanization accelerator. In the rubber vulcanization process, sulfur and rubber are mainly used for vulcanization reaction. However, the crosslinking reaction between sulfur and rubber is very slow. Therefore, adding the rubber vulcanization accelerator to the rubber compound can promote the activation of the vulcanizing agent, thereby accelerating the reaction speed of the vulcanizing agent and rubber molecules, shortening the vulcanization time, reducing the vulcanization reaction temperature, and reducing the amount of vulcanizing agent.

[0003] The application of rubber accelerators in the rubber vulcanization process can greatly improve the production efficiency of rubber products, reduce product costs, improve the physi...
