Description
Technical field
The present invention relates to pigment and preparation field thereof, relate in particular to multi-layer multi-color changing colour change interval pigment and preparation method thereof.
Background technology
Along with the development of pigment, people have developed high-performance effect pigment-camouflage paint of new generation.
So-called multiple-layer alteration paint can present the continuous variation of the color between two or more interference color with the viewing angle difference.
Oxide-coated reaches certain thickness with coating on flat substrates, when light is mapped to coatingsurface, a part is injected light wave and is reflected, part light is transmitted to down layer of surface by coating, produces reflection of light and transmission again, will produce " interference " phenomenon of light like this.If following n represents the coating refractive index, d is a coat-thickness, and then nd is the optical thickness of coating.Some catoptrical reflected light wavelength λ=2nd/N, N is a positive integer, is weakened by interference effect, other reflected light (λ=4nd/ (2N-1)) are enhanced.
When the oxide compound of high refractive index and the oxide compound of low refractive index alternately are coated on the flat substrates, when wherein two-layer or multilayer had identical optical thickness, so catoptrical color can increase along with the increase of the number of plies.But also can be by suitable design and the thickness of selecting coat, also can be strong especially as the color change of visual angle function.The basis that Here it is prepares strong interference pigment and effect interference pigment.
Present multiple-layer alteration paint is to pass through the multilayered structure that vapor phase process or wet chemical method coated metal oxide and nonmetal oxide form on the surface of substrate.Because the difference of substrate, the production method of its pigment is also inequality.Multiple-layer alteration paint is broadly divided into transparent (approximate transparent) and opaque (sub-opaque) two big classes, transparent (approximate transparent) is as the Color Stream pigment of German Merck company, be to be base material, and then carry out with wet chemical method that titanium dioxide or ferric oxide deposition coating make with the silicon-dioxide thin slice.The Varocrom pigment as German BASF AG of opaque (sub-opaque) is to be base material with metal aluminium flake or oxidation iron plate, coated silica again, and this process is finished in fluidized-bed reactor.
In recent years, it is base material that multinomial patent has proposed with nonmetal or metallic compound, adopted liquid-phase chemistry deposition technique, rely on high and low refractive index material alternate multiple cladding process to prepare the method for camouflage paint, because of every technology difference, the transition interval of camouflage paint is also different, mainly is two or three transition intervals.
