Problems solved by technology

In the polishing process of granite, polishing powder should be added. 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 single polishing powder can not achieve good polishing effect on granite

Embodiment 1

[0022] A kind of preparation of granite polishing powder: in reactor, add the ammonium dichromate of 6g, 12g zirconium oxychloride is dissolved in water, then add the aluminum oxide of 58g, add the titanium dioxide of 8g, add 1.0 tensio-active agent, Stir to form a slurry, then add 15g of ammonium carbonate, stir to dissolve, the sum of each component is 100%, water is not included in the component, under normal pressure, stir, add heat at 70°C, and react for 25h, so that the zirconium oxychloride produces uniform particles Zirconium dioxide particles, evaporated to dryness, then raised the temperature to 190°C, reacted for 3 hours to make ammonium dichromate produce uniform chromium trioxide, roasted at 1100°C for 1.5 hours, cooled, and crushed by airflow to obtain Granite polishing powder.

Embodiment 2

[0024] A preparation of granite polishing powder: in the reactor, add 10g of ammonium dichromate, dissolve 6g of zirconium oxychloride in water, then add 69.5g of aluminum oxide, add 2g of titanium dioxide, add 0.5 surfactant , stir to form a slurry, then add 12g of ammonium carbonate, stir to dissolve, the sum of each component is 100%, water is not included in the component, under normal pressure, stir, add heat at 75°C, and react for 30h to make the particles of zirconium oxychloride uniform The zirconia particles were evaporated to dryness, and then the temperature was raised to 195°C, and reacted for 2 hours to make ammonium dichromate produce uniform chromium trioxide particles, roasted at 1100°C for 1 hour, and after cooling, they were pulverized by air flow to obtain Granite polishing powder.

Embodiment 3

[0026] A kind of preparation of granite polishing powder: in reactor, add the ammonium dichromate of 12g, 17g zirconium oxychloride is dissolved in water, then add the Al2O3 of 50g, add the titanium dioxide of 10g, add 1.0 tensio-active agent, Stir to form a slurry, then add 10g of ammonium carbonate, stir to dissolve, the sum of each component is 100%, water is not included in the component, under normal pressure, stir, add heat at 75°C, and react for 20h, so that the zirconium oxychloride produces uniform particles Zirconium dioxide particles, evaporated to dryness, then raise the temperature to 190°C, react for 4h, make ammonium dichromate produce uniform chromium trioxide, roast at 1000°C for 2.0h, after cooling, crush by airflow to obtain Granite polishing powder.

Abstract

The invention discloses a preparation method of granite polishing powder. The method is characterized in that the method comprises the following steps: dissolving 3-12% by mass of ammonium dichromate and 6-18% of zirconium oxychloride in water, adding 50-70% of alumina, adding 2-10% of titanium dioxide, adding 0.5-1% of a surfactant, stirring to form a slurry, adding 10-20% of ammonium carbonate, stirring for dissolving, stirring under normal pressure, heating to 70-75DEG C, reacting for 20-30h, evaporate to dryness, heating to 190-195DEG C, reacting for 2-4h, roasting at 1000-1100DEG C for 1-2h, cooling, and carrying out air flow crushing to obtain the granite polishing powder. The preparation method has the advantages of simplicity, easy condition control, low production cost, and easy industrialized production. The granite polishing powder is used for the granite polishing process, and has the advantages of good polishing effect, glossiness, small scratch quantity, high flatness, and small amount.

Description

[0001] technical field [0002] The invention relates to a preparation method of granite polishing powder, in particular to a preparation process of granite polishing powder containing aluminum oxide, chromium oxide, zirconium dioxide and titanium dioxide. Background technique [0003] 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. But in recent years, with the improvement of living standards, people's aesthetic concept of their own living environment is also constantly updated, and marble and granite are also increasingly appearing in home decoration. Because marble generally co...
