技术领域technical 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 invention belongs to the field of chemical industry, and relates to a metal topcoat with an angle-dependent color effect and a preparation method thereof.
发明背景Background of the invention
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。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。The high-grade and high-performance requirements of automobiles force the development of automobile coatings to continuously improve their protection and decoration performance. The main focus is to improve the decoration of the car surface, improve the scratch resistance and anti-corrosion ability, and better protect the environment, especially the surface protection and decoration layer of the car body, which directly affects the appearance and appreciation of the whole car.
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、耐化学品性；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。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。The research and development and industrialization of nano-materials for modified automotive coatings started earlier in the United States and Germany, and the research and development of nano-modified automotive coatings started relatively late in China. CN1189522A, a patent for nano-metal automotive topcoats, was applied by Chu Yanming , it is made of acrylic resin, amino resin, polyester resin, cellulose resin as the base material, adding various pigments, metal nano-powders, fillers, additives, solvents through mechanical processing, the coating has a strong adhesion Focus on acid resistance, alkali resistance and chemical resistance; CN1253978A applied by people such as Wu Limin is a high scratch resistance car paint, which realizes high scratch resistance by improving the base material polyester resin of the paint. At present, there is no metal flash automotive topcoat technology and related patent reports modified by inorganic nanoparticles.
纳米TiO2(10-50nm)对可见光的透射能力很强，例如对550nm的可见光，透明度可达90％以上，具有极好的紫外光屏蔽性。当纳米级TiO2与铝粉颜料或云母珠光颜料混合用于涂料时，能得到产生随角异色效应的涂料。这主要是由于纳米TiO2本身既具有透明性，又具有对可见光一定程度的遮盖力，在与铝粉颜料等混合时，入射光一部分在散光铝粉表面发生镜面反射，而另一部分透过纳米TiO2发生色散后，在纳米TiO2与铝粉界面反射，形成散光涂层，因而具有独特的随角异色效应，加入不同颜色的珠光颜料，可以形成不同的正视色和侧视色。将纳米TiO2用于金属闪光汽车面漆中可以制备具有随角异色效果的金属面漆，用于轿车面漆、金属外装饰漆等。Nano TiO 2 (10-50nm) has a strong transmittance to visible light, for example, to 550nm visible light, the transparency can reach more than 90%, and it has excellent ultraviolet light shielding property. When nano-sized TiO 2 is mixed with aluminum powder pigment or mica pearlescent pigment for coating, it can get the coating with angle-dependent color effect. This is mainly due to the fact that nano-TiO 2 itself has both transparency and a certain degree of hiding power for visible light. When it is mixed with aluminum powder pigments, a part of the incident light is specularly reflected on the surface of the astigmatic aluminum powder, while the other part passes through the nano-particles. After the dispersion of TiO 2 occurs, it reflects at the interface between nano-TiO 2 and aluminum powder to form a light-scattering coating, so it has a unique color-dependent effect. Adding different colors of pearlescent pigments can form different front-view colors and side-view colors. The use of nano- TiO2 in metallic flash automotive topcoats can prepare metallic topcoats with angle-dependent color effects, which can be used for car topcoats, metal exterior decorative paints, etc.
