Properties of solution polymerized styrene butadiene rubber with different functional groups and carbon black or silica composites
The modified soluble polybutadiene rubber Sn-SSBR and Si-SSBR are synthesized through the functionalization initiator,which are compounded with carbon black and white carbon black respectively.The energy consumption of the composite material mixing process is used by the controller,the filler dispersion meter,the rubber processing analyzer.the rotorless vulcanizer and the dynamic thermodynamic analyzer.The physical and mechanical properties and dynamic properties of blended rubber,and vulcanized rubber have been studied.The results show that Sn-SSBR is more easily compatible with carbon black than Si-SSBR,which is characterized by lower processing energy loss during the mixing process of the former with carbon black,lower Mooney of the mixed rubber,good comprehensive physical and mechanical properties,and better balance of high wet skid resistance and low rolling resistance.The latter is more easily compatible with white carbon black,which is characterized by a more evenly dispersion of white carbon black in it and better low rolling resistance performance.Both can be used as green tire tread compounds.
