Sulfur, peroxide, quinone oxime, resin, metal oxide and other vulcanization systems can be used according to the requirements of rubber and rubber products.Among them, sulfur sulfide system is divided into ordinary sulfide system, effective sulfide system and semi-effective sulfide system.Sulfur curing system in general synthetic rubber and half use the more general synthetic rubber, metal oxide vulcanization system is mainly used for neoprene (CR), quinone oxime and resin curing system is mainly used for butyl rubber (IIR), peroxides and resin curing system is mainly used for ethylene propylene rubber (EPR), natural rubber (NR) and styrene-butadiene rubber (SBR).Special BCL (CBC) ᱫᱚ α-CLC (CBC), β-ᱥᱮᱱᱴ (CBC) (CBP), ᱜᱞᱩᱠᱚᱡᱽ (CBP), ᱜᱞᱩᱠᱚᱡᱽ (CBP) ᱨᱮ ᱠᱚᱢ ᱟᱠᱟᱱ HCP, α-CFC, ᱜᱞᱩᱠᱚᱡᱽ, ᱜᱞᱩᱠᱚᱡᱽ, ᱟᱨᱟᱵᱤᱰ-ᱤᱱᱯᱷᱞᱟᱢᱮᱴᱟᱨᱤ ᱥᱴᱨᱮᱱ, ᱟᱨᱟᱵᱤᱰᱟᱹᱣ (C) sulfur, so need to adopt the sulfur curing system, such as metal oxide, peroxide, organic amine salt vulcanization system, etc.In recent years, the acrylate rubber (ACM) has basically adopted sulfur vulcanization system.
(1)sulfur.Sulfur powder is the most commonly used vulcanizing agent in the rubber industry.With the development of radial tire and color rubber products, insoluble sulfur (IS), which does not spray frost, does not affect the adhesion performance and product appearance, IS widely used.IS IS mostly used in NR tire compound, which can improve the adhesion performance between compound ᱟᱨ loge , loge lạgit̕ lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ } } } ᱟᱨ 4.5 kDa} ᱠᱟᱱᱟ᱾

(5)Peroxide Sulfur donor.Sulfur donor is a vulcanizing agent that can decompose sulfur in the vulcanization process of rubber.Its adhesive is characterized by better heat resistance than sulfur adhesive, excellent compression deformation resistance, and good coke resistance, not easy to spray frost.However, most sulfur donors have been placed 4.5 mM MDMs ᱨᱮᱭᱟᱜ ᱜᱩᱱ, ᱡᱟᱦᱟᱸ ᱫᱚ ᱰᱤ ᱮᱱ ᱮ ᱟᱨ ᱰᱤ ᱮᱱ ᱮ ᱨᱮᱭᱟᱜ ᱢᱮᱠᱟᱱᱤᱡᱽᱢ ᱠᱚ ᱨᱮ ᱢᱤᱫ ᱞᱮᱠᱟᱱ ᱡᱤᱱᱤᱥ ᱠᱚ ᱨᱮᱭᱟᱜ ᱵᱷᱮᱜᱟᱨ ᱠᱚ ᱩᱫᱩᱜᱟ᱾
