Chemical Formula Of Rubber Additive

Source:

The r′ is H, R is an organic group, or r′ and r are organic groups; r′, R can also be a ring

By promoter M or its sodium salts, also by promoter DM, with cyclohexyl amine (product for the Promoter CZ), two cyclohexyl amine (product is promoter DZ), diisopropyl amine (product is promoter DIBs), Morpholine (product is promoter Nobs), tert-butylamine (product is NS) and so on through different process system. Their vulcanization starts slowly, but the vulcanization speed is fast, is called the late effect fast promoter, mainly uses in the tire and so on large-scale rubber product production. In conventional formulations, the dosage is only two-thirds of the promoter M and DM (the usual amount for the Promoter M and DM). In the so-called "semi-effective vulcanization" system (that is, low sulfur/high promoter coordination), the dosage is up to $number (with 0.2 ~ 0.4 sulfur use), can obtain good processing safety, and improve the comprehensive performance of vulcanized rubber.

③ Autumn Lamb is a rapid promoter, mainly for thiazole or secondary sulfonamide auxiliary promoter.

④ disulfide is a speeding accelerator, suitable for rapid vulcanization at ambient temperature, and also as an auxiliary promoter.

In addition, there are substances that can improve the activity of organic promoter, called vulcanizing active agent, that is to promote auxiliaries. The most widely used is zinc oxide, dosage $number. Prevent or delay the rubber material in the process before vulcanization and the production of early vulcanization ("Coke Burning") of the substance, called the vulcanizing agent, that is, Coke. The effective anti-Coke agent has n-nitrophenyl aniline (NDPA), N-cyclohexyl sulfide (PVJ or CTP), the former dosage of 0.3 ~ 1, the latter 0.1 ~ 0.5. The research work of the coke-proof agent is still active.
