摘要
耐高温尼龙在汽车、电子电器等领域具有广泛的应用,但目前高端耐高温尼龙被国外尼龙生产巨头所控制,国内主要依赖进口。本文在总结国内外耐高温尼龙的种类,主要制备工艺,改性和应用研究进展。重点分析了耐高温尼龙的合成工艺和功能化改性方向,并指出开发新工艺,寻找新原料,合理调控耐热性能是目前国内企业的主要发展方向。
The high temperature resistance is widely used in auto industry and electrical industry. The synthesis and high-performance nylon with well heat resistance is monopolized by international enterprises,i. e.,Dupont and much of the consumed high-performance nylon is imported from these international enterprises. The classification,synthesis method and technology,modification and application of high temperature resistance nylon were comprehensive introduced.The key progress of technology of semi-aromatic nylon,development of new technology and new raw materials were the key factor to fasten the R&D high temperature resistance. Some proposals were put forward for the future development of high temperature resistance nylon.
