Problems solved by technology

Therefore, in the polishing powder, the change of the chemical composition will lead to a change in the adhesion between the polishing film and the marble, and also lead to changes in the temperature and concentration of the polishing powder in the working area, which will eventually affect the polishing efficiency.

Abstract

The invention discloses a method for preparing blue marble polishing powder. The method is characterized by comprising the following steps: (1) preparing an AlN-ZrO2 complex, namely adding the following components: 40-60% of water, 20-26% of zirconium oxychloride, 30-36% of nano aluminum nitride and 1-5% of sodium hydroxide, stirring and reacting at a room temperature for 30 minutes, performing solid-liquid separation, drying at the temperature of 105+ / -2 DEG C, roasting at the temperature of 550+ / -10 DEG C for 2 hours, cooling, and performing air jet milling so as to prepare the AlN-ZrO2 complex; and (2) adding the following components into a grinder: 40-45% of oxalate dehydrate, 18-22% of the AlN-ZrO2 complex and 4-8% of cupric oxalate, grinding, uniformly mixing, adding 8-12% of ammonium binoxalate and 18-24% of stearic acid, grinding, uniformly mixing, adding 0.3-1.0%of a nonionic surfactant, uniformly mixing, thereby obtaining the blue marble polishing powder. The polishing powder has the chemical polishing characteristic. Therefore, the polishing powder is excellent in polishing effect, high in glossiness, less in scratch, high in flatness and small in usage amount.

Description

technical field [0001] The invention relates to marble surface treatment technology, in particular to a preparation method of blue marble polishing powder containing abrasives, oxalic acid and auxiliary agents. Background technique [0002] With its natural and simple texture, marble has bright and bright colors, and has the advantages of no deformation, high hardness, good rigidity, strong wear resistance, small temperature deformation, long service life, no scratches, and no magnetization. Therefore, marble is a major category of natural architectural decorative stones, which generally refer to decorative functions and can be processed into architectural stones or handicrafts. Marble is mainly used to be processed into various shapes and plates, and used as walls, floors, platforms, and columns of buildings, and is a precious material for furniture inlays. It is also commonly used as a material for monumental buildings such as monuments, towers, statues, etc. The quality...
