Problems solved by technology

Different pearlescent effects can be produced by changing the metal oxide thin layer. The publication number CN102127321A discloses a preparation method of a golden yellow pearlescent pigment with high color density and high brightness. Multi-layer coated iron and titanium oxide film, by precisely controlling the thickness of the oxide film to achieve the required different hues, and then calcining the coated mica substrate at a set temperature to dehydrate and transform the crystal form of the film to achieve To achieve the pre-designed thin film interference effect, the golden yellow pearlescent pigment with high color concentration and high brightness produced by this method still has a certain gap compared with the color of pure gold, and the brightness is not enough, which cannot meet the requirements of jewelry manufacturers. Demand; Publication No. CN100560658C discloses a super-interference golden pearlescent pigment production process, which is based on mica, and mica flakes are coated with four layers of metal and non-metallic oxides to obtain a golden pearlescent pigment with 24K gold effect, but in There is no pretreatment of the mica substrate before production, the production cost is high, there is still a certain gap between the produced product and the color of pure gold, the brightness is poor, and it cannot meet the needs of jewelry manufacturers. The needs of jewelry manufacturers have developed a pearlescent pigment with a thousand pure gold effect and its preparation method

Abstract

The invention discloses a pearlescent pigment having 999-pure gold effect and a preparation method thereof. The pearlescent pigment includes a base material, which is successively coated with a firstcomposite layer, a second composite layer, a third composite layer, a fourth composite layer and a fifth composite layer; wherein the first composite layer is formed by mixing stannous chloride, magnesium chloride and zinc chloride; the second composite layer is formed by mixing titanium tetrachloride, nickel chloride and stannic chloride; the third composite layer is formed by mixing titanium tetrachloride and ferric chloride; the fourth composite layer is formed by silicon dioxide or alumina; the fifth composite layer is formed by mixing titanium tetrachloride and ferric chloride. The preparation method includes steps of: surface pretreatment of the base material, hydrolytic coating of the base material, and post-treatment. The pearlescent pigment has a bright color, is high in purity ofgolden color, is good in glossiness, weather resistance and dispersibility, is low in cost, is simple in preparation method, and is convenient to use.

Description

technical field [0001] The invention relates to a pearlescent pigment, in particular to a pearlescent pigment with a pure gold effect and a preparation method thereof. Background technique [0002] Pearlescent pigments are composed of thin layers of several metal oxides coated with mica. Different pearlescent effects can be produced by changing the metal oxide thin layer. The publication number CN102127321A discloses a preparation method of a golden yellow pearlescent pigment with high color density and high brightness. Multi-layer coated iron and titanium oxide film, by precisely controlling the thickness of the oxide film to achieve the required different hues, and then calcining the coated mica substrate at a set temperature to dehydrate and transform the crystal form of the film to achieve To achieve the pre-designed thin film interference effect, the golden yellow pearlescent pigment with high color concentration and high brightness produced by this method still has a ...
