Modification of SSBR/BR with Trans-1,4-Polyisoprene Alloy Rubber for High Performance Passenger Car Radical Tire Tread Stock
摘要
Abstract
The crystalline characteristics, processing and mechanical properties of trans-1, 4-polyisoprene alloy rubber( TPIR) were studied. Then TPIR incorporated with solution polymerized butadiene-styrene rubber (SSBR)/cis-1,4-polybutadiene rubber(BR) blends were further investigated as passenger car radical(PCR) tire tread stocks. Compared with amorphous SSBR and BR, TPIR raw rubber showed improved green strength due to its crystallizability at room temperature. The capillary extrusion behavior of TPIR indicated that TPIR presented good extrusion behavior with smooth extrusion appearance and low extrusion swelling ratio. SSBR/BR/TPIR compounds showed increased green strength and 100% modulus with the increase in TPIR, when compared with SSBR/BR blends. After vulcanization, SSBR/BR/TPIR vulcanizes showed excellent physical and mechanical properties, such as increased wet skid resistance, wear resistance, compressive strength, and outstanding tensile fatigue resistance( increased by more than 4 times) . Carbon blacks and silica were proved to be dispersed much more uniformly in SSBR/BR/TPIR vulcanizates with much smaller aggregates than in SSBR/BR vulcanizates. So comprehensive speaking, TPIR as a novel synthetic rubber has the potentional application in PCR tire tread stock with superor performance.关键词
