2017 is a key year for the development of the environmental protection industry, and people's awareness of environmental protection has been generally improved. For the coating industry, all over the country “ Oil to water ” Under the background that the policy continues to enter the implementation period, the traditional solvent based coatings have entered the production capacity elimination period. The development of modern water paint production capacity is the general trend of future industry development, and the market prospect of water-based coatings in China is promising

hazards of traditional solvent based paint

research shows that paint is both a source of haze and a health ERODER. The important reason for haze weather is PM2.5. The main sources of its generation are automobile exhaust emissions accounting for 30%, VOC (volatile organic compounds) emissions accounting for 21%, and other residues discharged through combustion in daily power generation, industrial production and other processes accounting for 49%, Recently, it has been reported that about 18% of VOC emissions are caused by solvent based paint emissions

paint needs to be diluted with the help of organic solvents extracted from oil and coal, which not only consumes fossil energy, but also contains a large number of toxic and harmful substances such as benzene, toluene, xylene, formaldehyde, etc., and its volatilization period is as long as more than ten years. Traditional paints often use a large number 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 aplastic anemia, leukemia, tuberculosis, pleurisy and other serious diseases

everywhere “ Oil to water ” The policy has entered the implementation period

water based coatings use water as the dispersion medium. Generally speaking, water-based coatings are mixed with water. What evaporates during the spraying and drying process is water, and its VOC emission is very small. Solvent based coatings have a lot of diluents in the process of painting and drying, that is, organic solvents will volatilize and produce a lot of VOC. The data shows that the VOC emission of water-based coatings can be reduced by 60% compared with solvent based coatings& mdash; 70%。 Therefore, water-based coatings are more and more popular

in June 2015, Beijing issued the emission standard of furniture pollutants, which pointed out that from January 1, 2017, the furniture manufacturing industry in Beijing will completely prohibit the use of oily coatings, namely paint spraying, and replace all oily coatings in Beijing with water-based coatings

October 10, 2016, “ Shenzhen standard ” One of the Shenzhen Special Economic Zone's technical specifications, "limits of harmful substances in finished furniture and raw and auxiliary materials", has been reviewed and approved by the Shenzhen Municipal People's government for implementation. The provisions mean that the use of solvent based coatings and solvent based adhesives will be comprehensively banned in Shenzhen from May 1, 2017

in March this year, Xi'an released the "2017 “ iron fist haze control road and blue sky protection ” “ 1+1+9&rdquo"; combination plan, which clearly stipulates that since April, diluents containing high volatile toxic and harmful substances are prohibited from being sold on the market, and at the same time, the control of volatile organic compounds in the coating industry is strengthened

breaking through the core technology is the key to the development of the water-based coating market.

from the current development trend of the global coating industry, we can see that China has become a major paint producer and consumer in the world, but it lags far behind Europe and the United States in promoting the popularization of environmentally friendly coatings. Relevant statistics show that the average penetration rate of environmental friendly coatings in Europe has reached 80%&mdash& mdash; 90%, while the penetration rate of environmental protection coatings in first tier cities such as Beijing and Shanghai is less than 25%. It can be seen that there is still a huge market potential for more environmentally friendly water-based coatings. With the increasingly strong development of China's coating industry, the water-based coating market is bound to be driven by the overall upward trend of coatings and get a share. The current water-based paint market is in urgent need of a group of industry elites with R & D capabilities, capital and technical support to lead the water-based paint towards a healthy development

aqueous polymer technology introduces hydrophilic groups on the polyurethane chain segment, and disperses polyurethane particles in water through strong dispersion to form aqueous polyurethane. Foreign waterborne polyurethane technology the preparation and application of waterborne polyurethane resin is the core technology of waterborne Ketian and the basis of various projects. Waterborne Ketian has a number of patented technologies of polysiloxane diols, and the waterborne polyurethane produced has good water resistance; Post chain extension, re chain extension technology and solvent-free preparation method can make the molecular weight of waterborne polyurethane reach one million and the strength of the product reach 60MPa, which can fully reflect the advantages of polyurethane performance; At the same time, the traditional waterborne polyurethane production adopts intermittent production, while the waterborne Ketian uses semi continuous production, which greatly improves the efficiency and production capacity, and has the first 100000 ton waterborne polyurethane production line in China. In a word, the raw materials of patented technology, advanced synthesis process and production line suitable for large-scale production are the core advantages of water-based

the market prospect of water-based coatings is promising

the data shows that the demand for water-based coatings in China in 2016 was about 1.89 million tons, accounting for less than 10% of the coating industry. With the accelerated promotion of water-based coatings in steel structures, furniture, containers and other fields, it is expected that by 2022, the market demand for water-based coatings in China will reach 6.34 million tons, with a compound growth rate of more than 20%& ldquo; Oil to water ” The introduction of the policy has brought benefits to water-based coating enterprises. It is believed that the popularization and application of water-based coatings in China will make long-term progress
