Abstract

The invention discloses eco-friendly waterproof paint and belongs to the technical field of paint. The eco-friendly waterproof paint comprises, by weight, 70-96 parts of low-heat portland cement, 0-10 parts of fly ash, 0-10 parts of limestone powder, 4-15 parts of dispersible latex powder, 0.3-0.5 parts of cellulose ether and 0.5-0.8 parts of a water reducer. The eco-friendly waterproof paint has the advantages of environmental friendliness, good water resistance, high later strength, good use performance and low cost.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to an environment-friendly waterproof coating. Background technique [0002] There are several kinds of waterproof materials on the market. One is polyurethane waterproof coating, which is 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 polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as a raw material. However, when using this kind of paint, it is generally diluted with organic solvents such as toluene and xylene, so it is also toxic; the commonly used waterproof paint on the market is a two-component waterproof paint, one of which is latex. To improve the film-forming performance of coatings, organic solvents are usually added to the latex, so that the content of volatile organic solvents and free formaldehyde is high, and pungent od...
