Problems solved by technology

This method is relatively simple and fast, but the overall performance of water resistance, chemical resistance and adhesion is poor.
At the same time, because the film-forming agent is only coated and colored on the surface of the quartz sand, it cannot penetrate into the inner layer of the sand, and it is easy to discolor due to mutual friction during stirring.
Moreover, since the coloring agent is an oily resin, there is a great potential risk of compatibility in water-based sand wall paints.
2. Sintered colored sand, patent application number CN2014104129789 discloses a kind of quartz sand as raw material, adding high-temperature resistant inorganic pigments and low-temperature ceramic glaze as binder, and sintering at a high temperature of 500-1100°C. Composed of four stages of heating, calcination and cooling, the obtained colored sand has stable performance, but the energy consumption is high, and the colorant used is an inorganic ceramic binder, which is wrapped on the surface of the quartz sand to form a thin and brittle film.
Color is more affected by calcination problems and less stable
3. Water-based dyed colored sand, the patent application number CN2015103950049 has announced a kind of dyeing agent compounded with water glass and resin emulsion, and the method for dyeing colored sand by dyeing quartz sand with the dyeing agent, but because the method is too complicated, it is not used The operation of condensed aluminum phosphate is uncontrollable during curing, which makes the final product unstable and not environmentally friendly

Abstract

The invention discloses sand wall like coating containing water-based dyeing colored sand and a preparation method of the sand wall like coating .At present, a method for obtaining water-based dyeing colored sand by dyeing quartz sand with a dyeing agent prepared by compounding water glass and resin emulsion is provided; because the method is too complex and not controllable in operation when curing is conducted through condensed phosphoric acid, the final product is not stable enough and neither environmentally friendly .The sand wall like coating is prepared from, by mass, 260-320 parts of base slurry and 680-740 parts of water-based dyeing colored sand .The water-based dyeing colored sand is prepared from, by mass, 1000 parts of broken stone material and 120 parts of water-based composite dyeing agent, wherein the broken stone material is quartz sand .By means of the water-based dyeing colored sand, the production time of the sand wall like coating is shortened, production efficiency is improved, and production cost is reduced.
