Abstract

The invention discloses a gloss-adjustable inorganic powder composition for extinction and application of the gloss-adjustable inorganic powder composition and belongs to the technical field of delustering agents. The inorganic powder composition is composed of porous silicon dioxide powder and fused quartz powder; the porous silicon dioxide powder is formed by aggregation of nano silicon dioxide,and the nano silicon dioxide is connected through chemical bonds to form a pore passage interpenetrating structure. When the composition of the porous silicon dioxide powder and the fused quartz powder is applied to paint, coating and printing ink, the glossiness, viscosity and vertical flow resistance can be adjusted within a large range, and different requirements of customers are met; meanwhile, the two kinds of powder have clear and obviously different effects, and when quality fluctuation occurs, the source can be easily and rapidly found, and the problem can be solved in a targeted mode.

Description

Technical field: [0001] The invention relates to the technical field of matting agents, in particular to an inorganic powder composition with adjustable glossiness and matting and its application. Background technique: [0002] Paints, coatings and inks have a very broad and important application in different industries, such as furniture, home decoration, industrial coating, automobiles, high-speed rail, aircraft, ships, and electronics industries, which are beautiful, dustproof, easy to clean, Important role such as anti-corrosion. [0003] The brightness and extinction degree of paints, coatings and inks not only affect people's visual and aesthetic feelings, but also affect people's personal and property safety in more important fields, such as transportation and other fields. Excessively bright surfaces are prone to strong reflections, which threatens the personal safety of pedestrians, drivers and passengers. Therefore, it is necessary to perform matting treatment on paints...
