橡胶材料硫磺硫化体系低锌/无锌技术研究进展

硫化是决定橡胶是否能够作为材料使用最为重要的步骤。橡胶硫磺硫化体系中，氧化锌的使用不仅可以改善橡胶的硫化性能，并且能够大幅度提高橡胶制品的物理机械性能。但是，由于游离的锌离子易迁移至环境，会对水生生物等产生危害，所以欧盟和美国加州相继颁布法案限制氧化锌的使用。另外，锌矿产资源也日渐枯竭。因此，减少锌元素在橡胶配方中的应用，是保护环境并保证橡胶硫化反应正常进行的热点研究课题。该综述介绍了目前橡胶硫磺硫化体系配方中减少硫化活化剂氧化锌的用量和用非含锌化合物替代氧化锌的研究进展，包括纳米氧化锌、有机锌复合物、无机填料载锌技术、其他金属氧化物和稀土型多功能橡胶硫化剂等新型硫化活化剂的研究现状，并对未来发展方向进行展望。

Research Progress in Low Zinc/Zinc-free Technology for Sulfur Vulcanization System

Vulcanization is the most important step in determining whether a rubber can be used as a material. Sulfur vulcanization system, the use of zinc oxide can not only improve the rubber vulcanization performance, and can greatly improve the physical and mechanical properties of rubber products. However, since the zinc ions easily migrate to the environment, would be harmful to aquatic organisms, so the European Union and the California have enacted legislation restricting the use of zinc oxide. In addition, zinc mineral resources are increasingly depleted. Therefore, the reduction of zinc in rubber formulations of the application is to protect the environment and to ensure that rubber vulcanization reaction to the normal hot research topics. This review introduces the current progress in reducing the amount of zinc oxide as a vulcanizing activator, including nano-zinc oxide, zinc complexes, inorganic filler loading zinc, other metal oxide and rare-earth-based multi-functional rubber vulcanizing agent, etc. In addition to prospects for future development.
