应用
Application		 1.交联活化促进剂 , 具有高效催化作用的叔胺复合体 , 目前用于乙烯 / 丙烯酸酯橡胶等 , 能激活
这些酸性基团和二胺之间反应促使交联反应的快速进行。
Tertiary amine complex which acts as a powerful Lewis base with a high catalytic effect. It was originally
developed for use in ethylene acrylate copolymers (ACM/AEM)with acidic pending groups. It activates
the reaction between acidic groups and diamine cross-links.
2、活化效率优于传统助剂 , 较少用量即可达到既定硫化密度
Less amount can achieve the same cross-linking dens as usual activators.
3、在丙烯酸酯橡胶的HDC硫化配方中,与18D搭配可替换DOTG,且硫化胶的杭热老化性能更优。
In the HDC curing system of ethylene acrylate copolymer,synerging with 18D can replace DOTG while
bring better properties after heat aging.
 
以下 AC-55、 Vulcofac ACT-55 在丙烯酸酯橡胶中替代 DoTG 的对比实验结果显示 : 两实验配方的
胶料门尼粘度、交联密度有所增加 , 卲 A 硬度增加 5 度左右 ; 焦烧时间略微缩短 , 工艺正硫化时间
略有延长 ; 拉伸度、100% 定伸有所提高 ; 撕裂强度、扯断伸长率降低 ; 对压变性能略有影响。
AC-55 和 Vulcofac AC-55 仕胶料加工性能、化特性、常规物理机械性能、热空气老化性能、
压变性能方血都很接近 , 可以互相替代。
Based on the following experiment result of ac-55 and Vulcofac act-55 replacing DOTG
in Ethylene Acrylate Copolymer;The two experiment recipes enable the vulcanizates' Mooney
viscosity and cross-linking density increase;Shore A Hardness increases about 5HA;Scorch
time is slightly shortened,while the optimum cure time is a little bit longer;There is an increase
in tensile strength and 100% modulus and decrease in tearing strenght and elongation at
break;And the compression set is slightly influenced.
Ac-55 and Vulcofac ACT-55 have shown similar performance in processing property,curing
property,regular mechanical property,hot air aging property and compression set,so a
conclusion can be drawn that they can substitute each other.
