一种具有随角异色效果金属面漆及其制备方法 Metal finish with optically variable effect and preparation method angle has

技术领域 FIELD

本发明属化工领域,涉及到一种具有随角异色效果金属面漆及其制备方法。 The present invention belongs to the field of chemical industry, it relates to a metal effect finishes flop having its preparation method with angle. 发明背景汽车的高档化、高性能化要求迫使汽车涂料的发展不断提高其保护与装饰的性能。 Background of the invention of automobiles gentrification, high performance requirements forced development of automotive coatings continue to improve the performance of protection and decoration. 主要集中在提高汽车表面装饰性,提高耐刮伤性和防腐能力以及更好地保护环境方面进行努力,特别是汽车车身的表面保护装饰层,更直接影响到整车的外观和可观赏性。 Focused on improving the surface of decorative car, improving scratch resistance and corrosion resistance and better protect the environment efforts, in particular the surface of the car body protective decorative layer, but also directly affect the appearance of the vehicle and can be ornamental.

纳米材料用于改性汽车涂料的研究开发和产业化方面以美国和德国起步较早,国内在纳米改性汽车涂料的研究开发方面起步较晚,褚炎明申请的CN1189522A为纳米金属汽车面漆的专利,它是由丙烯酸树脂、氨基树脂、聚酯树脂、纤维素树脂为基材料,加入各种颜料、金属纳米粉、填料、助剂、溶剂经机械加工制造而成,涂层具有极强的附着力、 能耐酸、耐碱、fe—化学品性;武利民等人申请的CN1253978A为高耐刮伤性轿车漆,它是通过改进漆的基料聚酯树脂来实现高耐刮伤的。 Research and development and industrialization of nano materials for the modification of automotive coatings in the United States and Germany started earlier, in China started research and development of nano-modified aspects of automotive coatings late, CN1189522A Chu Yanming application of nano-metal patented automotive finish , which is an acrylic resin, an amino resin, a polyester resin, a cellulose resin as the base material, addition of various pigments, metal nano powders, fillers, additives, solvents made of machined, coated with a strong attachment focus, to acid, alkali, chemical resistance Fe-; CN1253978A Limin Wu et al., filed high scratch resistance car paint, which is achieved by improving a high scratch paint binder a polyester resin. 目前国内还没有以无机纳米粒子改性的金属闪光汽车面漆技术及相关专利报道。 Currently no inorganic nanoparticles modified metal flash automotive topcoat technology and related patent reports.
