摘　　要：合成乙基黄原酸锌(促进剂ZEX)、正丁基黄原酸锌(促进剂ZBX)和正丁基黄原酸钠(促进剂SIX),研究黄原酸盐烷基链长度和金属元素(锌和钠)对天然胶乳硫化和硫化胶膜力学性能的影响。结果表明:促进剂ZBX的热稳定性最好,促进剂ZEX次之,促进剂SIX最差;黄原酸锌盐类促进剂ZBX和ZEX促进硫化的作用较强,黄原酸钠盐类促进剂SIX促进硫化的作用较弱;促进剂ZBX和ZEX用量为2份时,硫化胶膜的力学性能最佳;烷基链较长的黄原酸锌盐类促进剂ZBX促进硫化的效果优于促进剂ZEX。Zinc ethyl xanthate(ZEX),zinc n-butyl xanthate(ZBX)and sodium n-butyl xanthate(SIX)were synthesized.The effects of alkyl chain length of xanthate and metal elements(zinc and sodium)on natural latex vulcanization and mechanical properties of vulcanized film were investigated.The results showed that,thermal stability of accelerator ZBX was the best,accelerator ZEX was the second,and accelerator SIX was the worst.Zinc xanthate accelerators ZBX and ZEX had strong promotion effect of vulcanization,while the effect of sodium xanthate accelerators SIX was weak.When the dosage of accelerators ZBX or ZEX was 2 phr,the mechanical properties of the vulcanized film were the best.The effect of zinc xanthate accelerator ZBX with longer alkyl chain was better than that of accelerator ZEX.
