Abstract

The invention discloses a preparation method of polishing powder for granite polishing. The preparation method is characterized by comprising the following steps: (1) preparation of a ZrN-ZrO2-SiN2 compound: adding the following components: 42-48% of water, 25-30% of zirconium oxychloride, 10-15% of zirconium nitride and 10-15% of silicon nitride, performing stirring for dissolution, adding 2-4% of sodium hydroxide, performing stirring reaction at a room temperature, performing solid-liquid separation, drying, roasting, and crushing to obtain the ZrN-ZrO2-SiN compound; and (2) preparation thepolishing powder for granite: adding 32-38% of the ZrN-ZrO2-SiN compound, 12-18% of oxalic acid and 12-18% of ammonium binoxalate, performing grinding and uniform mixing, adding 15-20% of ammonium fluoborate and 15-20% of stearic acid, performing grinding and uniform mixing, adding 1.0-2.0% of sodium dodecyl sulfate, and performing grinding and uniform mixing to obtain the polishing powder for granite. The polishing powder has the characteristics of chemical polishing, and has a good polishing effect, high glossiness, few scratches, and high flatness and a small usage amount, and the corrosionof oxalic acid can be buffered with the addition of the ammonium bioxalate.

Description

technical field [0001] The invention relates to stone surface treatment technology, in particular to a preparation method of polishing powder for granite polishing. 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%, and the quartz content is 20%-40%. It...
