Problems solved by technology

Therefore, in the polishing powder, the change of the chemical composition will lead to the change of the adhesion between the polishing film and the terrazzo, and the change of the concentration of the polishing powder, which will eventually affect the polishing efficiency and the brightness of the polishing.

Abstract

The invention discloses a preparation method of polishing powder for polishing a water grindstone. The preparation method is characterized in that a Cr2O3-Fe2O3-SnO2 compound is used as a grinding material, oxalic acid is used as an acidic polishing agent, and additives including a dispersant, a surfactant and the like are added to prepare the polishing powder. The specific preparation method comprises the following steps: in a grinding machine, adding the following components according to the following mass percent concentration: 10 percent to 15 percent of the Cr2O3-Fe2O3-SnO2 compound, 50 percent to 55 percent of oxalic acid dihydrate and 15 percent to 20 percent of ammonium bioxalate; grinding the materials and uniformly mixing; adding 4 percent to 8 percent of rosin powder and 6 percent to 12 percent of stearic acid, and grinding and uniformly mixing; adding 1.0 percent to 3.0 percent of a non-ionic surfactant, wherein the sum of all the components is 100 percent; grinding and uniformly mixing to prepare the water grindstone polishing powder. The polishing powder disclosed by the invention has a good polishing effect, high glossiness, fewer scratches, high flatness and a small dosage; the ammonium bioxalate is added so that the corrosion performance of the oxalic acid can be buffered.

Description

technical field [0001] The invention relates to terrazzo surface treatment technology, in particular to a preparation method of polishing powder for terrazzo polishing. Background technique [0002] Terrazzo (also known as terrazzo) is a product made by mixing gravel, glass, quartz stone and other aggregates into cement binder to make a concrete product, and then grinding and polishing the surface. The terrazzo made of cement binder is called inorganic terrazzo, and the terrazzo made of epoxy binder is also called epoxy terrazzo or organic terrazzo. According to the construction process, terrazzo is divided into on-site pouring terrazzo and prefabricated plate terrazzo floor . Traditional terrazzo has a huge market in China due to its unique advantages such as low cost, optional color mosaic, and convenient construction. There are as many as one billion square meters of terrazzo floors used in various buildings in urban and rural areas across the country. Abrasion-resistan...
