example 1

[0027] Take hydrogenated bisphenol A epoxy resin 4.6g, light stabilizer UV-320: 0.0046g and antioxidant 1010: 0.0046g; aliphatic polyamine curing agent 0.23g, chlorine-containing epoxy resin 0.5g and flame retardant 0.05g is made into a binder.

[0028] Take 100g of 0.4-0.2mm mesh quartz sand dyed into cyan, and then take 0.12g of glycidoxypropyl trimethoxysilane as a coupling agent. After mixing, it is formed into a permeable brick by mold, which has good flame retardancy and durability. Excellent performance, test the comparison of its performance indicators with ordinary permeable bricks:

Abstract

The invention discloses a weatherability permeable binding agent, which is composed of one or random composition of good weatherability epoxide resin, polyurethane resin and acroleic acid resin, wherein the good weatherability epoxide resin is added aliphatic polyamine or alicyclic polyamine hardener with weight rate at 5-60%, which also contains polyurethane solidifying reacting catalyst; the good weatherability epoxide resin, antioxidant and optical stabilizer are blended together to improve anti-oxidant and anti-ultraviolet property.

Description

technical field [0001] The invention relates to a binder, in particular to a binder with good weather resistance and strong water permeability that can be used for making water-permeable products. Background technique [0002] At present, the world is facing a shortage of energy and water resources. At the same time, the expansion of desertification area and the frequent occurrence of sandstorms make the living environment of human beings worse day by day. 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 directly infiltrating into the ground, and the accumulation of water on the ground makes it very inconvenient for people to travel; precious w...
