Rubber Accelerator Major Significance in Today's Industry
The natural rubber is the raw material of the rubber accelerator "universal". Natural rubber by various vulcanizing agent, and skills with extensive access to the performance of different types. In view of this method is simple, synthetic rubber developed today, there are still a great practical significance.
1, rigid rubber: hardened rubber configuration essentials is mainly to improve the elongation stress and hardness, have certain skills in the configuration process, the selection of the complexing agent vulcanizing agent.
2, the tensile strength of rubber: the configuration of the tensile strength of the rubber essentials is to pay attention to the degree of filler dispersion, multi-segment mixing storage, and to ensure adequate sulfide. With the vulcanization agent selection skills ① selection and good reinforcing carbon black, silica; ② amount of sulfur should not be too small; (3) complexing agent vulcanizing agent pure, free of impurities.
Elongation of rubber: rubber elongation configuration essentials including plastic rate higher degree of cure of the vulcanizing agent shallower. With the vulcanization agent selection techniques (1) to add softener, but note that permanent deformation changes; (2) less filler vulcanizing agent, be better to clay, calcium carbonate; ③ less sulfur; the ④ accelerator and vulcanizing agent used H or M, DM, and H is used.
4, the high resilience of rubber: high resilience rubber configuration essentials to keep a high content of raw rubber, fully cured. Skills with the agent vulcanizing agent selected ① use the right amount of soft black best MT, FT; ② sulfur to maintain appropriate.
