Abstract

The invention provides a water-permeable coating, and a preparation method and an application thereof. The water-permeable coating comprises modified resin and a modified curing agent, wherein the mass ratio of the modified resin to the modified curing agent is 1: (0.1-0.6); the modified curing agent comprises a curing agent and an auxiliary agent in a mass ratio of 1: (0.05-0.3); and the modifiedresin comprises resin and a diluent in a mass ratio of 1: (0.05-0.3). The coating prepared by taking the modified resin and the modified curing agent as raw materials has water permeability and low viscosity; when the water-permeable coating is sprayed onto a water-permeable pavement for repairing, pores of the water-permeable pavement cannot be blocked, that is, the water permeability of the water-permeable pavement cannot be affected; meanwhile, the water-permeable coating is low in viscosity and good in flowability, can form a horizontal spraying layer on the water-permeable pavement, realizes repairing of the water-permeable pavement, and is simple, convenient, quick and effective; and by limiting of the mass ratio of the modified resin to the modified curing agent, the curing time ofthe prepared coating can be prolonged, and the operability of the coating in the spraying process is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-permeable coating and its preparation method and application. Background technique [0002] At present, most of the roads in cities are hardened pavements paved with impermeable materials such as granite, marble, cement and asphalt; but the hardened pavement prevents the accumulated water from directly penetrating into the ground, and the heat and moisture of the ground surface and the air The exchange cannot be performed, resulting in poor ability of the hardened pavement to regulate the temperature and humidity of the urban ground, and the urban ground temperature is too high. Therefore, permeable pavement has become a new trend to replace hardened pavement, especially in sidewalks, parking lots and large public places in cities. [0003] However, after a long period of use of the permeable pavement, some sections of the road will have surface wear, or problems such a...
