摘　　要：研究了硫化剂种类、用量对氟橡胶硫化胶的物理性能的影响。结果表明 ,硫化剂用量增加 ,硫化胶的硬度增大 ,扯断伸长率降低 ,拉伸强度先增大后降低 ,出现一个极大值 ,硫化胶的压缩永久变形先减少后增大 ,存在一极小值。The effect of the kind and dosage of vulcanizing agent on the physical properties of fluorinated rubber was investigated.The hardness increased and the fracture extension ratio decreased with the increasing of vulcanizing agent content.The tensile strength showed a maximum value and the permanent deformation of compression showed a minimum value with the increasing of vulcanizing agent content.
