摘　　要：用无机盐(SDS和Ca Cl2)作为胶乳凝固剂,通过改变用量讨论不同用量对天然橡胶性能的影响。结果表明,当无机盐(SDS和Ca Cl2)分别为干胶含量的0.05%在力学性能方面最好;当无机盐(SDS和Ca Cl2)分别为干胶含量的0.2%硫化特性和热分析优于酸对照样;无机盐含量对无机盐凝固胶理化性能、分子量及分子量分布的差异不显著。The sodium dodecyll sulfate and caclcium chloride as natural rubber latex coagulation, the effect of natural rubber was discussed by changing for the different inorganic salt dosage. The results showed that the bset of mechanical properties is sodium dodecyl sulfate and calcium for 0.05 %, the sodium dodecyl sulfate and calcium for 0.2 % are higher than acid coagulation by vulcanization charecteristice, the physical and chemical properties, molecular weight and molecular weight distribution of different inorganic salt dosage are no significant.
