Abstract

The invention discloses a preparation method of powder for new materials. The preparation method includes following steps: S1, performing primary processing: selecting high-quality sericite raw ore, performing rough breaking the sericite raw ore, and using a rolling machine for rolling to obtain particles A; S2, performing secondary processing: placing the particles A in a reaction kettle, adding lithium chloride into the reaction kettle, setting a weight ratio of the particles A to lithium chloride to be 1-3:4-7, fully stirring at temperature of 70-90 DEG C for 20-40 min, and adding gamma-aminopropylmethyldiethoxysilane into the reaction kettle, fully stirring at temperature of 80-100 DEG C for 10-30 min to obtain a mixture B; S3, performing ultrasonic treatment: placing the mixture B in an ultrasonic wave generator for ultrasonic treatment for 2-4 h to obtain a mixture C, wherein ultrasonic power is 200-300 W; S4, drying and sterilizing. The preparation method is simple and high in production quantity, and the powder for the new materials is high in dispersity, glossy and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for preparing powder for new materials. Background technique [0002] Sericite belongs to monoclinic crystals, its crystals are scaly, silky smooth (muscovite is glass luster), pure blocks are gray, purple rose, white, etc., diameter-thickness ratio> 80, specific gravity 2.6-2.7, molar The hardness is 2-3, rich in elasticity, bendable, good wear resistance and wear resistance; heat-resistant and insulating, insoluble in acid and alkali solutions, and stable in chemical properties. The chemical composition, structure, and structure of sericite are similar to kaolin, and it has some characteristics of clay minerals, that is, good dispersion and suspension in aqueous media and organic solvents, fine white particles, and stickiness. Therefore, sericite has many characteristics of mica minerals and clay minerals. Sericite structure layers are usually piled up d...
