In the production and construction processes of the traditional waterproof coating, a large amount of volatile organic solvents and organic substances are released, so that resources are wasted, the environment is polluted, and the harm to the health of human bodies is great. Since the 50 s, environmental pollution problems occurred in the united states. The 66-year regulation was made in 1966, the limit was imposed on volatile organic solvents, and the environmental protection agency was established in 1970. The currently available regulatory technology scope (RACT) is defined in the paint production and construction management technical guidelines (CTG) established by the environmental protection agency in 1977. More strictly, the upper limit of Volatile Organic Compounds (VOC) is also specified. In addition to the united states, europe and other countries have taken steps to limit VOC emission concentrations. With the enhancement of environmental protection, the restrictions on VOC are more severe. Therefore, some countries in Europe and America have been researched and improved to provide so-called "green" coatings and resins. The water paint uses little or no organic solvent, thus fundamentally eliminating or reducing the problem of environmental pollution.
Therefore, with the increasing requirements of environmental regulations of various countries on organic volatile matters, the use of solvent-based paint is greatly limited, and the requirements of society on environmental protection can be met only by the introduction of water-based environment-friendly coatings.
