Effect of CMCS on Cure Characteristics of Natural Rubber

Abstract:

The effect of carboxymethyl chitosan (CMCS) as preservation on cure characteristics of nature rubber (NR) was studied, which compared with NR using ammonia water as preservative agent. The results showed that the induction period and optimum cure time of sample N (Ammonia water dosage is 0.15% of the mass of fresh latex), CMCS-1(CMCS dosage is 0.05% of the mass of fresh latex) and CMCS-2(CMCS dosage is 0.1% of the mass of fresh latex) were obviously decreased with the increasing of temperature, corresponding to Arrhenius equation perfectly. The maximum torque was linear dependence on curing temperature and decreased with the increasing of curing temperature. The relation of MH0 were as follows: N>CMCS-1>CMCS-2, respectively.
