The invention also discloses a preparation method for the environment-friendly weatherproof waterproof coating. The weatherproof waterproof coating provided by the invention has the advantages of simple preparation, low environmental pollution, strong adhesion and good water resisnce, acid and alkali resistance and high-temperature resistance.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to an environment-friendly, weather-resistant and waterproof coating 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 (resin) and th...
