摘要
将原30份丁苯橡胶制内胎的配方调整为40份,并相应的调整了其他助剂用量。使成品拉伸强度、拉断伸长率提高,永久变形减小,节省了天然橡胶用量。
The 30 formulations of preparing inner tubes by butadienestyrene rubbers were enlarged to 40 ones and at the same time, other assistants were adjusted,which increased the tensile strength and pulling elongation rate of finished products, decreased permanent deformation, saved the amount of natural rubbers.
