    China has published the national standard gb5020794 of technical code for roof engineering, which has made clear regulations on the quality requirements, construction methods and project acceptance of different types of waterproof coatings, which has played a positive role in the development of building waterproof coatings

    However, there is no mandatory standard for waterproof coating, and the market is chaotic, which needs to be further standardized

    In the decoration of kitchen and sanitation, waterproof is a necessary procedure, but in the ten compulsory national standards, there is no limit standard for harmful substances of waterproof coating, so we should further strengthen the management in family decoration

    Some families found that the smell in the bathroom and kitchen was relatively large after decoration

    After detection by the testing center, it was mainly due to the pollution caused by waterproof coating, and this kind of pollution is not easy to remove

    At present, there are two 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 volatilized by it is toxic and difficult to remove, so it was banned from use in China in 2000

    Polyurethane waterproof coating, which is still on sale, uses asphalt instead of coal tar as raw material

    However, when using this kind of coating, it is usually diluted with organic solvents such as toluene and xylene, which also contains toxicity

    The other is polymer cement based waterproof coating, which is made up of many kinds of waterborne polymers and high quality cement mixed with various additives

    The flexibility of polymer (resin) and the rigidity of cement are integrated, making it excellent in impermeability and stability
