备。其与环氧树脂的差别只是三元环中硫取代了氧,故二者有许多相似之处。但在许多方面二者也有明显的差异。如低分子量的环氧树脂是粘稠液体,而环硫树脂呈结晶状态。环硫树脂比相应的环氧树脂具有较高的固化速度,易于常温或低温固化,具有较 Prepare Its difference with the epoxy resin is only the sulfur in the three-membered ring replaces oxygen, so there are many similarities between the two. But in many ways there are also significant differences between the two. Such as low molecular weight epoxy resin is a viscous liquid, while the ring sulfur resin was crystalline. Ring sulfur resin than the corresponding epoxy resin has a high curing speed, easy to cure at room temperature or low temperature, with more
