Preferably, 15 parts of quartz, 100 parts of white marble, 100 parts of diabase, 2 parts of bayer yellow, 1 part of nano zinc oxide, 1 part of benzotriazole, 7 parts of iron oxide yellow, 1 part of iron black, 1 part of chrome yellow, 7 parts of titanium dioxide, 30 parts of feldspar, 30 parts of borax, 15 parts of latex, 2 parts of fluorite, 6 parts of potassium silicate, 18 parts of sodium silicate, 8 parts of kaolin and 15 parts of a ceramic coating solvent.
The invention also provides a preparation method of the isolation protection sand, which comprises the following steps:
step one: weighing quartz, white marble and diabase according to the weight, mixing, and crushing to obtain the aggregate with fineness of 20-80 meshes;
step two: mixing and stirring the aggregate with the Bayer yellow, nano zinc oxide, benzotriazole, iron oxide yellow, iron oxide black, chrome yellow, titanium white, feldspar, borax, latex, fluorite, potassium silicate, sodium silicate, kaolin and ceramic coating solvent by weight, and heating and drying excessive water in the mixing and stirring processes to obtain sand materials;
step three: and (3) placing the sand materials into a kiln body, rotating and heating, sequentially passing through a medium temperature region, a high temperature region, a constant temperature region and a cooling region, and discharging from the kiln, wherein the sintering temperature is 800-1600 ℃.
According to the technical scheme, the Bayer yellow, the iron black and the titanium dioxide are comprehensively used, various yellow colors can be called out, and the light resistance is better when the Bayer yellow, the iron black and the titanium dioxide are matched with nano zinc oxide and benzotriazole for use, so that the color cannot fade after long-time illumination. The potassium silicate, the sodium silicate and the sodium silicate can play a role of an accelerator, and auxiliary materials including pigments are easy to mix with the aggregate in the process of mixing materials by matching with latex, so that the method is beneficial to late kiln granulation. The protective sand has good cohesiveness with the bonding layer and the post-cast concrete, and the raw materials are common raw materials in the market, so that the cost is low, and the production cost is reduced.
