Problems solved by technology

Most of the vulcanizing agents currently used in the production of silicone rubber materials are traditional peroxide vulcanizing agents, such as 2,4-dichlorobenzoyl peroxide (DCBP, trade name "Double Two Four"), 2,5 -Dimethyl-2,5-di-tert-butylperoxyhexane (DBPMH, trade name also known as "double two five"), etc., this peroxide vulcanizing agent is prone to odor during use, and the vulcanization temperature , vulcanization speed is not satisfactory, the performance of the silicone rubber products produced is not ideal, and the application in many industries is limited

Abstract

The present invention relates to a double-component platinum catalyst curing agent. It includes agent A and agent B which can be uniformly mixed when they are used, in which the agent A is mixture of vinyl raw rubber, gas phase white carbon black and platinum complex, and the agent B is mixture of vinyl raw rubber, gas phase white carbon black, silicon oil whose end contains hydrogen and inhibitor. When the agent A and agent B are mixed, their mass ratio is agent A: agent B = (0.8-1.0)(1.0-1.5). Said invention also provides the preparation method of said double-component platinum catalyst curing agent.

Description

technical field [0001] The invention relates to a vulcanizing agent and a preparation method thereof, in particular to a two-component platinum catalyst vulcanizing agent and a preparation method thereof. Background technique [0002] In recent years, silicone rubber has been widely used in electronics, medical, aerospace, food hygiene and other industries. With the continuous improvement of the requirements of these industries, especially for biomedical food-grade polymer materials, special emphasis has been placed on silicon rubber. The safety of rubber materials must be harmless to the human body and meet food grade. Most of the vulcanizing agents currently used in the production of silicone rubber materials are traditional peroxide vulcanizing agents, such as 2,4-dichlorobenzoyl peroxide (DCBP, trade name "Double Two Four"), 2,5 -Dimethyl-2,5-di-tert-butylperoxyhexane (DBPMH, trade name also known as "double two five"), etc., this peroxide vulcanizing agent is prone to ...
