Abstract

The invention discloses a water-permeable paving material and a preparation method and application thereof. The water-permeable paving material comprises, by weight, 60-90 parts of quartz sand, 10-40 parts of Portland cement, 2-10 parts of hydrophilic epoxy resin binders, 0.5-5 parts of curing agents and 1-10 parts of water. The curing agents include one or more of aliphatic polyamine and cycloaliphatic polyamine curing agents or aromatic ring polyamine curing agents. The hydrophilic epoxy resin binders comprise, by weight, 500-950 parts of bisphenol A epoxy resin, 1-200 parts of surfactant span, 1-200 parts of surfactant tween and 0.001-0.005 part of catalysts, wherein the catalysts can be tetraethylammonium chloride, butyl triphenyl phosphorus bromide, benzyl triethyl ammonium bromide, benzyl triethyl ammonium chloride, 2- methylimidazole or optional combination of the above substances. The water-permeable paving material is prepared by uniformly stirring the quartz sand, the Portland cement, the water, the hydrophilic epoxy resin binders and the curing agents; and then placing the stirred mixture into a mould for molding and curing for 24 hours at the normal temperature prior to demolding. The water-permeable paving material is used for preparing pavement bricks, pavement slabs and sewage filtering prefabricated members by means of molding.

Description

technical field [0001] The invention relates to a water-permeable pavement material and its preparation method and application. Background technique [0002] At present, due to the needs of the development of the urban ecological environment, the urban ground is gradually covered by impermeable materials such as cement and asphalt to be covered by permeable pavement materials. The traditional method is composed of large particle skeleton and epoxy resin. However, during the use of epoxy resin, due to its lipophilicity and hydrophobicity on the surface, in order to make epoxy resin hydrophilic, it is necessary to try to introduce a hydrophilic molecular segment into its molecular chain or to prepare a complete solution. epoxy resin in water. However, the water-emulsified epoxy resins and hydantoin epoxy resins that are completely soluble in water have the disadvantages of large amount of resin and low wet compressive strength of water-permeable products.
