无铬鞣剂的研究现状与进展

Research status and progress of chrome-free tanning agents

生态皮革的制造已经逐渐成为传统皮革行业的未来之路,无铬鞣剂的开发能够从源头上避免铬资源的减少、含铬废弃物的污染等问题,同时可以解决潜在Cr^(6+)的致癌毒性,已经成为了行业的当务之急。本文根据无铬鞣剂的基本结构特点,对金属无铬鞣剂、有机无铬鞣剂还有有机-金属结合鞣剂的鞣制特点,及其与皮胶原纤维的结合原理进行归纳汇总与分析,并且综述了各类无铬鞣剂的研究进展,最后对其进一步的研究与发展方向进行了展望。本文系统综述了无铬鞣剂的研究现状和发展趋势,对无铬鞣剂的研究和开发有一定的指导参考意义。

Ecological leather manufacturing has gradually become the future of the traditional leather industry.The development of chromium-free tanning agents can avoid the reduction of chromium resources,the pollution of chromi­um-containing wastes and the potential carcinogenic toxicity of Cr^(6+) from the source,which is the primary goal of the industry.Based on the basic structural characteristics of chrome-free tanning agents,the tanning characteristics of chrome-free metal tanning agents,chrome-free organic tanning agents,chrome-free organic-metal combination tan­ning agent and the principles of their combination with skin collagen fibers were summarized and analyzed.Then the research status of various chrome-free tanning agents was reviewed.Finally,its further research and development di­rection were prospected.The research status and development trend of non-chrome tanning agents were systematically reviewed,which has certain guiding and reference significance for the research and development of non-chrome tan­ning agents.
