摘　　要：研究了双-[γ-(三乙氧基硅)丙基]四硫化物(TESPT)对白炭黑补强溶聚丁苯胶料的硫化过程的影响。发现使用ASTM D1646-2015测试,并不能准确的反应白炭黑补强胶料的焦烧行为。为了解决这个问题,使用了橡胶加工分析仪(RPA)不同应变下的时间扫描,将白炭黑聚集和橡胶硫化两个行为分开来研究。The effects of bis-[γ-(triethoxysilyl)propyl]tetrasulfide(TESPT)on the vulcanization process of white carbon black reinforced polystyrene-butadiene rubber were studied.It was found that testing with ASTM D1646-2015 did not accurately reflect the scorch behavior of white carbon black reinforced compounds.In order to solve this problem,time scanning under different strains of rubber processing analyzer(RPA)was used to separately study the two behaviors of white carbon black accumulation and rubber vulcanization.
