The application rate of foreign water paint is as high as 90%, and China accounts for less than 5%. What is the reason?

Traditional paint pollutes the environment, is toxic and harmful, and has basically been replaced by water paint abroad, but due to publicity, promotion and policy The reason is that paint is still popular, and it will take time to promote the use of paint. An important reason for haze weather is that VOC (volatile organic compound) emissions accounted for 21% of the main sources of PM2.5, and about 18% of VOC emissions are generated by solvent-based paint emissions.
In addition, paint must be diluted with organic solvents extracted from petroleum and coal, which not only consumes fossil energy, but organic solvents also contain a large amount of toxic and hazardous substances such as benzene, toluene, xylene, and formaldehyde, and their volatilization period is as long as ten. several years. The European Union banned the production of paint in 2004, but paint is still used in most parts of China.
Traditional paints often use a large amount of toxic and harmful volatile organic solvents as diluents, and some products also use curing agents containing free TDI, resulting in a large amount of air pollution. Studies have shown that long-term inhalation of volatile gases from these solvents and curing agents will lead to regeneration Obstructive anemia, leukemia, tuberculosis, pleurisy and other serious diseases.
Water paint is an upgraded product of traditional paint. It uses water as a thinner and does not contain benzene, toluene, xylene, and formaldehyde. Yang Yuande said that water-based coatings can greatly reduce VOC emissions compared to traditional solvent-based coatings. Not only can effectively reduce the impact on the environment, but also help reduce the potential probability of occupational diseases.
However, the reporter learned from interviews that water paint has low awareness in China, difficult to promote, few applications, and the standard is blank, and there are vicious competitions such as concept wars and price wars.
China does not have a unified water paint industry standard and national standard. The production and product application of formal enterprises mostly refer to international standards such as German TUV and EU SGS, while workshop-type production and processing plants and some enterprises have substandard and vicious production and sales behaviors. , Leading to vicious competition such as concept wars and price wars in China’s water paint market.
At the same time, foreign countries monopolize core technologies and high equipment maintenance costs. China’s compulsory and standard measures are not perfect, which directly restricts the development of China’s water paint industry.
The key point of water paint technology is high-performance water-based resins, but China’s high-performance stable synthetic resins mainly rely on imports, leading to the same performance, the price of water-based coating is higher than that of oil-based The paint is 20% higher, and the land restricts the promotion and use of water paint.
China should formulate a mandatory VOC emission policy and gradually implement it in phases to restrict pollution-based oil paints. At the same time, encourage and support the development of the water paint industry, give preferential treatment and support in taxation and industrial layout, and guideThe coating industry develops in a green and clean direction, and promotes technological innovation and industrial upgrading in the water paint industry. While the government has introduced mandatory laws and regulations to limit VOC pollution emissions, it has also set industry entry thresholds, and has the right to speak and set prices.
