【摘要】 <正> 四丙氟橡胶系四氟乙烯-丙烯的交替共聚物,是近期研制成功的新型含氟弹性体。由于其化学惰性,故包括多胺、多酚类在内的大部分交联剂均无法使之硫化。 近年来国外已用差示扫描量热(DSC)法来研究硫化放热反应与硫化交联反应的关更多还原

【Abstract】 Using differential scanning calorimetric method, studies were carried out on the curing characteristics of tetra-fluoroethylene-propylene elastomer for its cure mechanism, cure temperature, type and dosage of vulcanizing agents, mechanism and dosage of accelerators. The results obtained can be used as the basis for determining the vulcanization conditions for this f luoroelastomer.更多还原
