有机过氧化物常用于饱和烃类橡胶的硫化,但硫化胶的交联程度和物理性能与硫化条件密切相关。实验发现:当过氧化物用量增加时,硫化胶的交联程度也增加;硫化温度上升同样也使交联程度增加,如果温度超过180°C。交联程度却开始下降,这是因降解效应的增加所致。 Organic peroxides commonly used in the vulcanization of saturated hydrocarbon rubber, but the degree of crosslinking and physical properties of the vulcanizates are closely related to the curing conditions. The experimental results show that when the amount of peroxide is increased, the crosslinking degree of the vulcanizate increases; the vulcanization temperature also increases the degree of crosslinking, if the temperature exceeds 180 ° C. The degree of crosslinking began to decline, which is due to the increase of the degradation effect.
