Problems solved by technology

[0004] However, after the current waterproof coating forms a coating on the base surface, as the use time goes by, cracks will inevitably appear, resulting in water seepage. Then such cracks or water seepage are not easy to be found, resulting in more and more serious water seepage, which in turn affects The overall water resistance of the coating will seriously shorten the service life of the waterproof coating

Abstract

The invention discloses a self-stripping waterproof coating and a preparation method thereof, and belongs to the technical field of waterproofness, a self-stripping net can be pre-buried in the coating in advance, the strength, especially the crack resistance, of the coating can be improved in an assisted mode, meanwhile, a tight water seepage sensing net can be formed, and once a water seepage phenomenon occurs on the surface of the coating, the water absorption fiber rods on the self-stripping net can rapidly absorb water, convey the water into the water collection base balls and then indirectly convey the water to the hydrolysis balls in the trigger pipes, impact is formed on a water seepage area on the surface of the coating from the edge of the self-stripping net by means of the characteristic that the hydrolysis balls react with water to release a large amount of gas, and then self-stripping of the water seepage area is achieved. Meanwhile, when the gas is released to the outside, the permeation water can flow back and does not easily continue to permeate, so that an excision operation similar to a lesion part is realized, further erosion of the permeation water to the coating is reduced, and technicians can be prompted to repair the coating in time.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to a self-peeling waterproof coating and a preparation method thereof. Background technique [0002] The waterproof paint is painted on the surface of the building, and a thin film is formed after the chemical reaction between the components, which isolates the surface of the building from water, thus playing the role of waterproof and sealing. The waterproof film formed after the waterproof coating is cured should have certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. [0003] There are two types of waterproof materials on the market: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. The tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000. The ...
