Description
Technical field
The invention belongs to the prescription and the preparation field thereof of pigment, particularly relate to a kind of pearlescent pigment dispersion formula and preparation method thereof.
Background technology
Pearly pigment is a kind of translucent microplate shape pigment that can produce pearl effect.This class pigment can be divided into natural and artificial two big classes.
As far back as existing this class pigment production twenties in 20th century, all milling with fish scale at first forms, and belongs to natural product, and the pearly pigment of Sheng Chaning costs an arm and a leg in this way.Use at present seldom, begin one's study the beginning of the fifties and produce the pearly pigment of multilayer iron oxide covering on sheet mica.The sheet mica of coating of titanium dioxide is the most widely used pearly pigment at present, and this pearly pigment is different with other general color pigments, and it is to produce color by reflection of light and refraction.
1978, German coating expert Su Tanuxi (Solpanush) was applied to nacreous mica pigment flash metal luster car finish paint first.Thereby greatly promoted the development of world car coating and application techniques.By 2000, the new car in the whole world nearly 40% adopted this novel effect pigment.This pigment not only has certain tinting strength and opacifying power, and its pearlescent effect is compared obvious enhancing with single coating.Because the pearlescent effect of its flicker, bright and colourful effect and stable chemical property are widely used in many fields such as coating, glossy black, plastics, rubber, art ceramics, makeup.China is that the development of pearly pigment is started late to mica, but the unremitting effort by the scientific worker, the product level of pearly pigment has had fast development, but up to now, also do not have excellent property, addition is few, has the pearlescent pigment of good consistency.
