Abstract

The invention relates to a natural stone imitated stain-resistant water permeable brick and a preparation method thereof. The natural stone imitating stain-resistant water permeable brick comprises a brick body, wherein the surface of the brick body is coated with stone imitating paint; the stone-like coating is prepared from the following raw materials in parts by weight: 20-30 parts of phenolic resin powder; 10-14 parts of a fluorocarbon emulsion; 6-8 parts of polylactic acid; 4-5 parts of modified magnesium aluminum hydrotalcite; 3-4 parts of 2-methoxy ethyl acetate; 8-9 parts of an inorganic pigment; 5-7 parts of deionized water; 1-2 parts of a coalescing agent; the invention relates to a preparation method of a natural stone imitating stain-resistant water permeable brick. The preparation method comprises the following steps: preparing a stone imitating coating; preparing a brick body; and spraying a stone-like coating to finally obtain the stone-like water permeable brick. The pollution-resistant stone-like coating prepared by mixing the phenolic resin powder and the fluorocarbon emulsion is adopted; particles of the modified magnesium-aluminum hydrotalcite improve the regularity of the coating and the flatness of the surface, increase the contact angle between a pollution source and the coating, and are mixed with polylactic acid to form a uniform physical net structure, so pollutants are not easy to adhere, and the pollution resistance of the water permeable brick is improved.

Description

Technical field [0001] The present application relates to the technical field of penetrating bricks, in particular, involving a preparation method of stain resistant bricks of natural stone. Background technique [0002] The water-based brick is a new product for environmentally friendly building materials that solves the city's surface hardening, creating high quality natural living environment, and maintaining urban ecological balance. Due to its structural characteristics of its high permeation and high porosity, the road area water is eliminated, and the groundwater resources are supplemented in time, reduce the foundation sink, alleviate the pressure of urban flood drainage and dredging of pipelines; on the other hand through the brick hole hole The evaporation of the medium moisture reduces the heat absorption and "heat island effect" in the city, and the noise pollution of the city is effective. [0003] For the pursuit of the quality of the water, it is still the directio...
