A kind of preparation method of granite polishing powder

Abstract

The invention discloses a preparation method of granite polishing powder. The preparation method is characterized by comprising the steps of (1) preparation of ZrN-CeO2-SiO2 compounds: the following ingredients including 38 to 44 percent of water, 25 to 30 percent of cerium chloride, 15 to 20 percent of zirconium nitride and 8 to 12 percent of silicon dioxide are added; after stirring and dissolution, 4 to 8 percent of ammonium hydroxide is added; room-temperature stirring and reaction are performed for 40 min; solid-liquid separation is performed; drying and roasting are performed for 2h; cooling and smashing are performed to prepare the faint yellow ZrN-CeO2-SiO2 compound; (2) preparation of granite polishing powder: the following ingredients including 22 to 28 percent of ZrN-CeO2-SiO2 compounds, 10 to 15 percent of oxalate dihydrate and 15 to 20 percent of sodium oxalate are added, are ground and are uniformly mixed; 20 to 25 percent of ammonium fluozirconate and 20 to 25 percent of palmitic acid are added, and are ground and uniformly mixed; 2.0 to 4.0 percent of paraffin powder is added; grinding and uniform mixing are performed to obtain the faint yellow granite polishing powder. The characteristic of chemical polishing is realized, so that the polishing effect of the chemical polishing powder is good; the glossiness can reach 98 degrees or higher; the scratch number is small; the flatness is high; the consumption is low.

Description

technical field [0001] The invention relates to stone surface treatment technology, in particular to a preparation method of granite polishing powder containing abrasives, fluorides and auxiliary agents. Background technique [0002] The facing stone materials used for architectural decoration and decoration mainly include marble and granite. Marble is mainly used indoors, and granite is mainly used outdoors, both of which are high-grade finishing materials. Using marble and granite as interior and exterior finishes has good decorative effect and durability, but the cost is high, so it is mostly used in public buildings and projects with high decorative grade requirements. Granite is formed by igneous rock, which is a kind of steel-hard lens stone. It was originally formed by feldspar and quartz and mixed with one or more black minerals. It is arranged evenly in structure. Granite is mainly composed of quartz, feldspar and mica. Among them, the feldspar content is 40%-60%...

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 granite, and the change of the concentration of the polishing powder, which will eventually affect the polishing efficiency.
