Problems solved by technology

[0004] At present, the main raw materials of some permeable bricks and permeable pavements in the field of building materials on the market are ceramics or concrete, and a large amount of mineral resources and cement are used. The mining of raw materials causes damage to the environment; the production process of ceramic permeable bricks is complicated. , and ceramic-based bricks consume a lot of energy when forming and sintering, high cost, low production efficiency, large investment in environmental protection, and large one-time investment scale; concrete bricks also use a lot

Abstract

The invention discloses a weatherability permeable material, which consists of aggregate and adhesive, wherein the aggregate is one of natural quartz sand, coal ash, melt slag, artificial quartz sand or their random composition with diameter at 0.07mm-1. 6mm; the adhesive is one of epoxide resin, polyurethane resin and acroleic acid resin or their composition with good weatherability; the optical stabilizer, anti-oxidizer and adhesive are added in the raw material, which improves weatherability obviously; the permeable resin is added in the aggregate as well as inorganics, which improves permeability effectively.

Description

technical field [0001] The invention relates to a water-permeable material, especially a water-permeable material with good weather resistance and good water-permeable effect applied in the fields of building materials, rainwater collection, water filtration and purification. Background technique [0002] At present, the lack of energy and water resources in the world, the expansion of desertification area and the frequent occurrence of sandstorms have made the living environment of human beings worse and worse. At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The urban environment is very dangerous. When it rains, the hardened ground completely prevents the rainwater from penetrating directly into the ground, and the accumulated water on the ground makes p...
