Abstract

The invention belongs to the field of machine manufacturing and particularly relates to a processing method for nano SSBR (Solution-polymerized Styrene Butadiene Rubber), wherein the SSBR is formed by processing a SSBR2305 base,SSBR321, new carbon black, adjuvants and a vulcanization system; the adjuvants comprise an antiager, an accelerant, a nano flame-retardant compound, nano-ZnO, A151 and Mg(OH)2; the SSBR2305 base and SSBR312 are blended, the adjuvants are added into the blended rubber and stirred for 35 min, 50 phr of new carbon black is added into the blended rubber and stirred uniformly, the blended rubber is added into the sulfur-free vulcanization system to be vulcanized for 50 min, and the temperature of the vulcanization system is 150 DEG C. The nano SSBR prepared by the method has the advantages of high production efficiency and high product percent of pass, excellent physical and mechanical properties, good low heat generation property and wide application prospect.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a nanometer SSBR rubber processing method. Background technique [0002] SSBR rubber is an elastomer synthesized by anionic solution polymerization of styrene and butadiene under the trigger of organic lithium. In addition to maintaining the original characteristics of rubber, it also has more excellent properties than natural rubber, such as wear resistance, heat resistance, aging resistance and vulcanization speed compared with natural rubber, and can be used with natural rubber and various synthetic rubbers. Widely used in the production of tires, tapes, hoses, wires and cables, medical appliances and various rubber products. At present, SSBR rubber is in demand in various fields and has a good application prospect. Its applicable working conditions (medium, temperature, pressure) depend on the scope of work. However, due to the difficulty in the productio...
