Embodiment approach

[0047]As a preferred embodiment of the present invention, the crystal particle diameter of the chloride chloride is 10-15 μm; preferably, the shape of the chloride chloride is a square or an octave.

[0048]In a preferred embodiment of the present invention, the diameter of 10-15 μm, the shape of a regular shape of square or octagon has a better brightness, suede effect, and hiding power; with this regular The shape of a sheet-like chloride chloride is a substrate, and the colored chloride pigment obtained by coating an organic pigment has a more excellent brightness.

[0049]Preferably, the organic pigment is at least one of red, yellow, and blue; preferably, the red is at least one of the amaranth, carmine and temptation; and / or, the yellow is a lemon At least one of Yellow and Sunset Yellow; and / or at least one of bright blue and indigo.

[0050]It should be noted that the present invention has no special limits for the source and type of organic pigments, and the organic pigment of c...

Embodiment 1

[0109](1) Preparation of solution containing chloride chloride

[0110]In the 5L beaker, 3000 ml of deionized water was added, and 3 g surfactant olelamine SV / 12 was added, and the mixture was stirred at a rate of 250 rps, the temperature was 10 ° C, and the pH of the solution was 1, which was added at 0.8 ml / min. 100 ml of 0.5 mol / L nitrate solution (the solvent of the nitrate solution is a hydrochloric acid solution having a mass fraction of 10%), and the pH of the solution is maintained unchanged at 30% NaOH solution. After the addition is complete, the addition of chloride-containing solutions is obtained. .

[0111](2) Preparation of yellow chloride pigments

[0112]In a solution containing chloride-containing chloride, the pH of 6 is adjusted with 30% sodium hydroxide solution, resulting in a solution containing a chloride of chloride in 70 ° C and 250 rps of a solution of 70 ° C and 250 rps. Next, in step (1), the pH of the pH of 6 ml is added to a solution containing 1 ml / min...

Embodiment 2

[0114]In the solution obtained by step (1), a solution containing a hydracene chloride solution was adjusted with 30% sodium hydroxide solution to obtain a solution containing chloride containing chloride of pH 6, at 70 ° C and 250 rps. Under the conditions of stirring, 100 ml of 0.02 g / ml of red pigin solution (red pigment solution) was added at 1 mL / min at a rate of 1 ml / min at a rate of 1 ml / min. The solvent is a hydroxide solution having a mass fraction of 1%), and 80 mL of 1.87 mmol / ml of aqueous aluminum chloride solution was added at a rate of 0.8 ml / min. After 100 min, the reaction was stopped, and the prepared chloride pigment was prepared to a predetermined color phase, filtered, and the filter cake was removed, cooled to room temperature to give a red chloride pigment.

Abstract

The invention provides a colored bismuth oxychloride pigment and its preparation method and application, belonging to the technical field of cosmetic pigments. The invention provides a colored bismuth oxychloride pigment. The colored bismuth oxychloride pigment uses flake-shaped bismuth oxychloride as a base material, and the surface of the bismuth oxychloride is coated with an organic pigment. The present invention also provides the preparation method of the colored bismuth oxychloride pigment, comprising the following steps: adjusting the pH of the solution containing bismuth oxychloride to 5-7.5, adding an alkali solution containing an organic pigment and an aluminum salt to make the organic pigment Coated on the surface of bismuth oxychloride to obtain colored bismuth oxychloride pigment. The invention provides a colored bismuth oxychloride pigment, which is delicate in texture, has bright colors, strong luster, excellent texture and smooth skin feeling, and is suitable for the field of cosmetics; the colored bismuth oxychloride pigment of the present invention can be Various colors enrich the types of bismuth oxychloride products and broaden the application fields of bismuth oxychloride.

Description

Technical field[0001]The present invention belongs to the technical field of cosmetic pigment, and more particularly to a non-ferrous chloride pigment and a preparation method thereof.Background technique[0002]Chloride oxychloride, molecular formula: BiOCl, molecular weight: 260.48) For the positive wafer of silver, white-white bright crystal powder, open free white pearl gloss. Because of the non-toxicity of chloride, high gloss effect and smooth effect, low oil absorption, strong skin adhesion, bead effect, the chloride pigment gradually became an important raw material in cosmetic products, is widely used High-grade cosmetic products make it an important raw material in cosmetic synthesis, such as pour flour, nail polish, eye shadow, etc. However, the current chloride color color is single (silver), which has not been able to meet the needs of consumers on cosmetics.[0003]In view of this, the present invention is proposed.Inventive content[0004]It is an object of the present inve...
