The invention discloses a special weather-resistant pearlescent powder coating for aluminum materials, which is formed by bonding together a base powder and a pearlescent pigment at a weight ratio of 100:0.003-10. The pearlescent pigment is a weather-resistant pearlescent pigment. The aluminum material of the invention The special weather-resistant pearlescent powder coating has excellent characteristics such as non-toxic and environmental protection, strong adhesion to aluminum, boiling water resistance, mortar resistance and xenon lamp aging resistance. Various performance requirements and appearance requirements such as high adhesion, good chemical resistance and excellent physical properties of special pearlescent powder.

The invention relates to a method for solving dust pollution caused by pearlescent pigment applied to ABS coloring. The method comprises the following steps: preparing ABS into an organic solution form, adding the pearlescent pigment, a chemical modifier and a stabilizer in the ABS organic solution, stirring and mixing uniformly to prepare a pasty composite component body, mixing the pasty composite component body and the solid ABS particles needing to be colored according to a ratio, and heating and mixing, wherein the liquid solvent in the pasty composite component body is gradually volatilized, the ABS in the pasty composite component body enables the surfaces of the solid ABS particles to be coated with the pearlescent pigment, the chemical modifier and the stabilizer, the coloring process of the solid ABS particles is completed, and the method can be directly applied to production of ABS injection-molded products.

The invention provides a novel preparation method of fluoro-bismuth oxychloride. The method comprises the following steps: adding a saline solution containing fluorine, chlorine and bismuth as well as a sodium hydroxide solution into a reaction system consisting of concentrated hydrochloric acid and a surfactant; after the saline solution containing the fluorine, the chlorine and the bismuth is added into the reaction system, rapidly adding the sodium hydroxide solution in order that the pH value of the solution of the reaction system is 10; standing the solution for delaminating, and removing a supernatant; and washing an obtained solid through deionized water to obtain a fluoro-bismuth oxychloride sheet crystal. The fluoro-bismuth oxychloride sheet crytal has regular squares and regular octagons which are arranged orderly, and has excellent chemical stability as well as superior weather resistance and temperature resistance; and the effects of shielding force, brightness and the like of the crystal are improved effectively, and a fluoro-substitution proportion can be controlled according to different demands. The fluoro-bismuth oxychloride sheet crystal is low in the preparation cost and has high pearl performance, and the preparation method is easy and convenient to operate.
