In natural polyisoprene glove manufacturing industries, the selection of accelerators in the curing system is mainly determined by the curing characteristics, maturation time required, cross-link density and mechanical properties of gloves. In this study, a new accelerator replacing conventional ones in a typical glove manufacturing process, was studied in order to produce free carcinogen dipped article. The glove properties and performance prepared by using both conventional and new proposed accelerators were studied and compared. The use of a conventional accelerator tends to release carcinogenic chemicals namely N-nitrosamine and N-nitrosatable substances. These chemicals are restrained on dipped articles under the requirement of EN 71-12:2013. Xanthogen accelerators promote the reduction of carcinogenic chemicals, but they are associated with prolonged maturation hour, which is unfavourable in the manufacturing industry. This study used a mixture of a benign accelerator, namely, diisononyldithiocarbamate and diisopropyl xanthogen polysulfide, to substitute the usage of conventional accelerators zinc dibutyl dithiocarbamate and zinc diethyl dithiocarbamate. The effects of benign accelerator loading in latex compounds were studied by focusing on the swelling index, maturation hour, carcinogenic chemical released and mechanical properties, thermal degradation and stability. Results showed no presence of N-nitrosamines and N-nitrosatable substances in the final dipped products by using 0.3 and 0.5 phr of benign accelerator. This study showed that 0.5 phr of benign accelerator achieved a moderate pre-vulcanising rate and improved the pre-ageing tensile strength and elongation by 11% and 7.0%, respectively. Moreover, its thermal stability was higher and discolouration intensity was lower as compared with the conventional accelerator.

在天然聚异戊二烯手套制造行业，固化体系中促进剂的选择主要取决于手套的固化特性、所需的熟化时间、交联密度和机械性能。在这项研究中，研究了一种替代典型手套制造过程中传统促进剂的新型促进剂，以生产游离致癌物质浸渍制品。研究和比较了使用传统和新提出的促进剂制备的手套性能和性能。使用传统促进剂往往会释放致癌化学物质，即 N-亚硝胺和 N-亚硝基物质。根据 EN 71-12:2013 的要求，这些化学品在浸渍物品上受到限制。黄原促进剂促进致癌化学物质的减少，但它们与成熟时间延长有关，这对制造业不利。本研究使用了一种良性促进剂的混合物，即二异壬基二硫代氨基甲酸酯和二异丙基黄原多硫化物，以替代传统促进剂二丁基二硫代氨基甲酸锌和二乙基二硫代氨基甲酸锌的使用。通过关注溶胀指数、熟化时间、致癌化学物质释放和机械性能、热降解和稳定性，研究了良性促进剂负载对胶乳化合物的影响。结果表明，通过使用 0.3 和 0.5 phr 的良性促进剂，最终浸渍产品中不存在 N-亚硝胺和 N-亚硝基物质。本研究表明，0。5 份良性促进剂实现了适度的预硫化速度，预老化拉伸强度和伸长率分别提高了 11% 和 7.0%。此外，与传统促进剂相比，其热稳定性更高，变色强度更低。
