· 物化性质
正丁醛苯胺缩合物(促进剂808)呈棕红色或琥珀色粘稠油状液体,有特殊气味,闪点135℃。溶于苯、乙醇、汽油,不溶于水。隔绝空气时储藏稳定,否则储藏过久,色泽变深,相对密度增加,但不影响效力。
· 产品用途:
正丁醛苯胺缩合物(促进剂808)可用作天然橡胶及胶乳用较强的促进剂,也可以用作酸性促进剂的活性剂。硫化临界温度为120℃,最宜硫化温度范围为120~160℃。适用于再生胶胶料和硬质胶,不宜用于氯丁橡胶,但可用于含一氧化铅的氯丁胶浆。在胶料中分散性好,易为瓦斯炭黑所吸附,当用量高于其吸附量时,硫化胶回弹率高。秋兰姆、胍类及噻唑类促进剂能增加其活性,与这些促进剂并用得到坚韧老化的制品。在胶乳胶料中是一种较慢的促进剂。
