A pollution-resistant permeable brick imitating natural stone and its preparation method

Abstract

This application relates to a pollution-resistant permeable brick imitating natural stone and its preparation method; a pollution-resistant permeable brick imitating natural stone, including a brick body coated with imitation stone paint; the raw materials of the imitation stone paint include the following parts by weight Components: 20‑30 parts of phenolic resin powder; 10‑14 parts of fluorocarbon emulsion; 6‑8 parts of polylactic acid; 4‑5 parts of modified magnesium aluminum hydrotalcite; 3‑4 parts of 2‑methoxyethyl ethyl Ester; 8-9 parts of inorganic pigments; 5-7 parts of deionized water; 1-2 parts of film-forming aids; a preparation method of a stain-resistant and permeable brick imitating natural stone, including preparing imitation stone coatings; preparing brick bodies ; Spray imitation stone paint, and finally get imitation stone permeable bricks. This application uses a pollution-resistant imitation stone coating mixed with phenolic resin powder and fluorocarbon emulsion; the particles of modified magnesium aluminum hydrotalcite improve the regularity of the coating and the smoothness of the surface, increase the contact angle between the pollution source and the coating, and combine with the poly Lactic acid is mixed to form a unified physical network structure, which makes it difficult for pollutants to stick and improves the pollution resistance of permeable bricks.

Description

technical field [0001] The present application relates to the technical field of permeable bricks, in particular to a pollution-resistant permeable brick imitating natural stone and a preparation method thereof. Background technique [0002] Permeable brick is a new product of environmentally friendly building materials born to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. Due to its structural characteristics of high water permeability and high porosity, on the one hand, it eliminates road surface water, replenishes groundwater resources in time, reduces foundation subsidence, and eases the pressure of urban flood control and drainage and pipeline dredging; The evaporation of water in the middle reduces the heat absorption of the urban bottom and the "heat island effect", and effectively reduces the noise pollution in the city. [0003] The pursuit of the quality of permeable bricks is still the dire...
