Abstract


In this paper, as the research object SBR1500 styrene , styrene-butadiene rubber does not change the basic additive synthesis route and the specifications of the conditions, the use of a variety of nitrosamine-free preparation is as a polymerization terminator terminator , the aggregation of using alkyl / aryl -p-phenylenediamine antioxidant EPPD, environmentally friendly terminated by dosage adjustments to ensure sample performance to superior grade SBR1500 national technical standards, styrene-butadiene rubber compound content of nitrosamines SBR1500E meet European environmental standards . The results show that eco- terminating agent ESD-050 has a good termination properties, can be used to prepare SBR1500E, condensation and drying process in no pungent odor , the Beijing Research and Design Institute for industrialized rubber test sample performance testing shows that environmental type SBR1500E the performance indicators have reached the national superior grade SBR1500 standards ; industrial installations mass production process has once again proven , environmentally favorable termination terminating agent effect , D500, VD501 graded composite terminating agent added to ensure the effects of large-scale production is terminated when to increase environmentally friendly terminator trialkyl ammonium chloride and increase the amount of green plastic modulus , cohesion blocking positions fixed screen does not appear linked to the phenomenon .
