Performance characteristics of rubber additives and their application in rubber

Rubber auxiliaries play an important role in the composition of rubber formula and are the primary factors affecting the function of rubber products. The application status of several kinds of rubber auxiliaries in the composition of rubber is introduced: 1. Vulcanization system auxiliaries are mainly composed of vulcanizing agent, accelerator and active agent, and their dosage accounts for about 10% of the amount of raw rubber. According to the plumpness of the constituent rubber, sulfur, metal oxides, peroxides and amine compounds can be used to vulcanize the system. 1.1+ vulcanizing agent According to the rubber and rubber products of different functional requirements, can choose sulfur, peroxide, quinone oxime, resin, metal oxide and other different vulcanizing system. Meanwhile, sulfur sulfide system is divided into general sulfide system, useful sulfide system and semi-useful sulfide system. Sulfur vulcanization system is used in general and semi-general rubber. Metal oxide vulcanization system is mainly used in neoprene rubber (CR), quinone oxime and resin vulcanization system is mainly used in butyl rubber (IIR), peroxide and resin vulcanization system is mainly used in ethylene propylene rubber (EPR), natural rubber (NR) and styrene butadiene rubber (SBR). Special rubber [such as polysulfide rubber (LP), chlorosulfonated polyethylene rubber (CSM), chlorinated polyethylene rubber (CM), fluorine rubber (F+K+M+), silicone rubber (M+V+Q+), fluorine silicone rubber (FVMQ), etc.) are all full rubber, do not contain double bonds, sulfur can not cross linking to it, so the need to choose non-sulfur sulfide system, Such as metal oxide, peroxide, organic amine salt vulcanization system. In recent years, acrylic rubber (ACM) has been fundamentally selected sulfur sulfide system.
