天然橡胶的有机促进剂-硫黄硫化是一个复杂过程,其硫化及促进机理取决于橡胶的结构、促进剂与活性剂(氧化锌及脂肪酸)的类型和用量及每个反应的反应热力学。硫化机理很复杂,所形成的交联键可能是单、双、三或多硫键,其各自数量比例主要取决于硫化体系、硫化时间和硫化温度。如 Sulfur vulcanization, an organic accelerator of natural rubber, is a complicated process. The vulcanization and promotion mechanism depends on the structure of rubber, the type and amount of accelerant and active agent (zinc oxide and fatty acid) and the reaction thermodynamics of each reaction. The vulcanization mechanism is very complicated. The formed cross-linking bonds may be single, double, triple or multi-sulfur bonds. The ratio of their respective quantities mainly depends on the curing system, curing time and curing temperature. Such as
