A Sduty on the Vulcanization Characteristic of Combined Accelerators in SBR compounds.

SBR의 가황촉진제(加黃促進劑) 병용효과(倂用效果)에 의한 가황특성(加黃特性) 연구(硏究)

The purpose of this study is to get comparitive results on the combined accelerator systems comprised of MBT, MBTS, DPG and CBS with TMTD, TMTM, Zn-MDC and DPG to SBR compound. Vulcanization characterstics and physical properties of the combined accelerators have been studied by mean of the Mooney viscometer, tensile testing machine, aging chamber and so on. According to the test results, TMTD with DPG system has shown faster Mooney scorch time than other system. The vulcanizate comprise of Zn-MDC with DPG and TMTD with DPG accelerator system has taken advantage of heat resistance.
