摘　　要：研究了天然橡胶和氯丁橡胶的共混工艺,并研究了NR/CR二者之间并用比例对并用胶性能的影响。结果显示,天然橡胶和氯丁橡胶分别加填料混炼均匀后再共混在一起,共混胶的各项物理力学性能较好,并用胶组成中,天然橡胶比重大时,硫化速度较快,但耐天候老化及阻燃性差。氯丁橡胶比重大时,耐溶剂性和阻燃性较好。Natural rubber and chloroprene rubber blends technology was developed and the effect of ratio between NR/CR on the property of the rubber was studied.The results showed that natural rubber and chloroprene rubber blends has the better mechanical properties.With more natural rubber in composition,the blend cures fast,and the flame resistance and weather aging performances of the rubber are poor,while with more chloroprene rubber in composition solvent resistance and flame resistance of the rubber are better.
