Application of weather-resistant permeable material

Abstract

The invention relates to application of weather-resistant permeable material used to be laid on pavement to form permeable pavement. The weather-resistant permeable material comprises aggregate and binder, wherein the aggregate is one or any combination of natural quartz sand, fly ash, smelting waste residue and artificial quartz sand; the particle size of the aggregate is 0.07 to 1.6 mm; and the binder is one or any combination of epoxy resin with good weather resistance, polyurethane resin and acrylic resin. By choosing the binder with good weather resistance and adding light stabilizers and antioxidants, the weather resistance is effectively improved. By choosing hydrophilic reactable resin with good water permeability and adding hydrophilic inorganic materials to the aggregate, the water permeability of the material is effectively improved. The application of the weather-resistant permeable material is that the raw materials can be mixed and prepared into permeable prefabricated parts used for road surfacing, rainwater collection or water filtration and can also be directly laid on pavement to form permeable pavement so as to promote the full utilization of rainwater resources and improve 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...

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
