随角异色颜料是第三代高性能效应颜料,它大致分为两类:透明的和不透明的。不透明随角异色颜料一般选用不透明的片状材料作为基片,然后用气相沉积法(VCD)或湿化学(WC)方法在基片上交替包覆上多层低折射率和高折射率的金属氧化物,从而产生随角异色效应。天然石墨鳞片是一种天然的不透明片状材料,在我国蕴藏十分丰富,价格很低。以天然石墨鳞片作为基片制备随角异色颜料具有广阔的应用前景。
Flutter pigments are the third generation of high performance effect pigments that fall broadly into two categories: transparent and opaque. Opaque isotropic opaque pigments are generally opaque sheet-like materials as the substrate, and then by vapor deposition (VCD) or wet chemical (WC) method alternately on the substrate coated with multiple layers of low refractive index and high refractive index of the metal Oxide, resulting in flop effect. Natural graphite flake is a natural opaque flake material, rich in our country, the price is very low. The natural graphite flake as a substrate preparation of the floppy pigment has broad application prospects.
