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 which can be used to make water-permeable products. Background technique [0002] At present, the world is facing shortages of energy and water resources. At the same time, the expansion of desertified areas and the frequent occurrence of sandstorms have made the living environment of human beings increasingly harsh. 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 people's travel very inconvenient; the precious water res...
