用途
Apoplications
本品为不变色、不污染的超促进剂，主要用于天然橡胶和合成橡胶。活性较促进剂TMTD低10%左右，硫化胶定伸强度也略低。硫化临界温度121℃，后效性比二硫化秋兰姆和二硫代氨基甲酸盐类促 进剂都大，抗焦烧性能优良。使用本品时硫黄用量范围较大。本品可单独使用，也可与噻唑类、醛胺类、胍类等促进剂并用，是噻唑类促进剂的活性剂。在通用型(GN-A型)丁胶中有延迟硫化的效应。在胶乳中与二硫代氨基甲酸盐并用时，能减少胶料早期硫化的倾向。本品不能分解出活性硫，不能用于无硫配合。
This product is non - color, non - pollution super accelerator, mainly used for natural rubber and synthetic rubber.The activity is about 10% lower than that of the promoter TMTD, and the fixed extension strength of the vulcanized rubber is also slightly lower. The critical curing temperature is 121°C, and the aftereffect is better than that of thiuram disulfide and dithiocarbamate promoters, and the scorching resistance is better. Sulfur dosage range is large when using this product.
