Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-seepage and anti-cracking waterproof coating with strong cohesive force and a preparation method thereof. Background technique [0002] 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 polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as a raw material. However, when using this kind of coating, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity; the other type is polymer cement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibility of the polymer and the ri...
