Problems solved by technology

[0005] 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 of cement, which also consumes a lot of resources; there are also some permeable bricks The materials used are natural stones and waste plastics, and its disadvantage is poor weather resistance and short service life;
[0006] The permeable bricks or permeable pavements mentioned above increase the water permeability by increasing the voids of the bricks, and the voids are above 20%. Since the problem of dust blocking the voids cannot be solved, high water permeability cannot be maintained continuously; and because of the large voids, It is also less effective for water filtration

Abstract

The invention relates to a weather resistance permeable material, comprising aggregate and binding agent, wherein, the aggregate is one of natural quartz sand, coal ash, smelting waste residue, artificial quartz sand or the arbitrary combination thereof; the grain diameter of the aggregate is 0.07 mm-1.6 mm; the binding agent is epoxy resin, polyurethane resin and acrylic acid resin with good weather resistance or the arbitrary combination thereof; the weather resistance is effectively improved by selecting the binding agent with good weather resistance and adding light stabilizer and antioxidant; and the water permeability of materials is effectively improved by selecting hydrophilic reactive resin with good water permeability and adding hydrophilic inorganic material in the aggregate. The application of the weather resistance permeable material is as follows: the above raw materials can be mixed to manufacture permeable prefabricated pieces used for road surfacing or rain water collecting and water filtering, and can also be directly paced on the road surface to form a permeable road surface, thus promoting full utilization of rain water resources and improving urban water circulation.

Description

[0001] This application is a divisional application of the parent application (application number: 2005101327365, the title of the invention is a weather-resistant water-permeable material and its application). technical field [0002] 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 [0003] 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 an...
