Problems solved by technology

In the polishing process of marble, it is necessary to add polishing powder. Now people are using aluminum oxide powder or other powders such as ferric oxide or chromium oxide, that is, using a single abrasive, that is, a single polishing powder for polishing, but This kind of single polishing powder can not achieve excellent polishing effect on marble

Abstract

The invention discloses a preparation method of marble composite polishing powder and application of the preparation method in a polishing process of marble production and refurbishment. The method comprises dissolving 5%-18% of zirconium oxychloride in water, adding 50%-65% of aluminum oxide, adding 10%-22% of stannic oxide, adding 2%-8% of silicon dioxide, stirring to be slurry, adding 10%-25% of urea, conducting heating reaction, solid-liquid separation, drying and roasting, mixing with lead powder according to the proportion of 10-25:1, and then obtaining the marble composite polishing powder. The preparation process is simple, preparation methods are easy to control, production cost is low, and industrial production is easy to achieve. The preparation method is used for a marble polishing procedure, the marble composite polishing powder has good polishing effects, glossiness can achieve more than 98 degrees, scratches are fewer, evenness is high, and using amount of the powder is less.

Description

technical field [0001] The invention relates to a preparation method of marble polishing powder, in particular to a preparation method of composite marble polishing powder containing zirconia, alumina and tin oxide. Background technique [0002] Marble has the advantages of no deformation, high hardness, good rigidity, strong wear resistance, small temperature deformation, long service life, no scratches, no magnetization, etc. Therefore, marble is a large 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 for processing into various shapes and plates, as the walls, floors, tables 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 texture of marble is soft, beautiful and solemn, elegant in style, and various col...
