The accelerator M gave larger plastication to NR than DM at lower temperature, but DM would give larger plastication than M as the temperature increased. 促进剂M的活化能比DM低得多,说明其硫化速度对温度的依赖性小于DM。
Triazine-mercaptan/ magnesium oxide/ accelerator DM or scorch retardant CTP curing system was environment-friendly, although it gave the vulcanizate somewhat poorer properties; 三嗪硫醇/氧化镁/促进剂DM或防焦剂CTP硫化体系的硫化胶性能稍差,但制品生产和应用环保性较好。
The effects of the addition levels of accelerator systems EG-3 or VP-148 on the properties and blooming of EPDM compound were experimentally investigated and compared to the common accelerator blend systems, such as M/ TMTD, DM/ TMTD/ BZ and M/ TRA/ BZ. 试验研究综合促进剂EG-3和VP-148用量对EPDM胶料性能和喷霜程度的影响,并与常用促进剂M/TMTD,DM/TMTD/BZ和M/TRA/BZ并用体系进行对比。
The influence of S-SBR/ BR, accelerator DM/ D and carbon black/ silica with different blending ratios on the physical properties of S-SBR/ BR tread was investigated. 用均匀设计方法研究了在选定变化范围内溶聚丁苯橡胶(SSBR)/BR、促进剂DM/D、炭黑/白炭黑的配比与SSBR/BR二元共混胎面胶物理性能的关系。
The effects of the conventional vulcanization ( CV), semi-efficient vulcanization ( SEV), efficient vulcanization ( EV), especially the levels of sulfur and accelerator DM on the properties of NR/ BR/ TPI ( 40/ 40/ 20) blend were investigated. 研究了普通硫化体系(CV)、半有效硫化体系(SEV)和有效硫化体系(EV)对NR/BR/TPI共混物(共混比为40/40/20)性能的影响,特别是CV体系中硫黄和促进剂DM用量的影响。
