Accelerating the process of "changing oil into water" and promoting the industrial application of coatings become the key

the 13th five year plan of the coating industry has clearly formulated the VOC emission reduction plan for coating in the automotive, marine, steel structure, container, engineering machinery, color steel and other industrial fields, which requires us to vigorously promote the low VOC coating, among which the development and application of water-based industrial coating is one of the key points. This will ensure that the proportion of low VOC green coatings specified in the action plan for volatile organic compounds reduction in key industries will reach more than 60% by the end of 2018. " Sunlianying, President of China Coating Industry Association, said at the recent founding meeting of the water-based industrial coating branch of China Coating Industry Association and the Green Development Summit Forum of water-based industrial coating

in fact, in recent years, with the continuous improvement of China's environmental protection laws and regulations and the enhancement of consumers' awareness of environmental protection, the paint market tends to be more healthy and safe, and the comprehensive "oil to water" is becoming more and more intense. In, the market scale of water-based coatings in China has increased from 35.3 billion yuan to 54billion yuan, with an average annual compound growth rate of about 9%. Some institutions predict that in the next five years, water-based coatings will grow at an average growth rate of 23%; By 2022, China's output of water-based coatings will reach 6.34 million tons

the process of "oil to water" is accelerated

few people know that the ubiquitous paint is also one of the factors causing haze. Because many solvents in oil-based coatings are extracted from petroleum, this extract contains a large amount of volatile organic compounds (VOC), which will pollute the air and endanger human health. Water based coatings can effectively reduce VOC emission and environmental pollution because water is used as solvent. Industry insiders said that the VOC emission of water-based coatings is 60%-70% lower than that of oil-based coatings, with obvious environmental benefits

in recent years, with the introduction of various environmental protection policies, a strong policy regulation has been carried out on the coating chemical industry. Environmental friendly coatings such as water-based coatings have ushered in rapid development opportunities, and the process of "oil to water" has been gradually accelerated

at present, the transformation of water-based coatings in architectural decoration coatings has been basically completed. At present, more than 95% of the interior and exterior wall coatings are water-based coatings

in the industrial field, water-based coatings are more and more favored by users. As a very important supporting enterprise in China's rail transit industry, Jinxi axle Co., Ltd. has been using water-based coatings since 2000. Chengping, the relevant person in charge of the company, said that at present, all freight cars of the company have used water-based paint, and locomotive maintenance has basically used water-based paint, including the painting of axles. "On the one hand, it is the support of policy orientation. On the other hand, it is also the responsibility of the enterprise itself. The use of water-based paint also ensures the health of the staff engaged in the coating industry."

as a key target of VOC in China, containers have been promoting water-based coatings as early as a few years ago. Recently, China's container industry has also defined the technical route for the unified promotion and application of water-based coatings throughout the industry; The product standards, process specifications, quality inspection standards and VOCs emission accounting standards for container water-based coatings have been formulated, and the development of water-based coatings in the container industry has been promoted by standardized means

wangaimin, chief engineer of Huabao (Tianjin) coating Co., Ltd., believes that the development of water-based industrial paint in China has been mature in technology, and the use of water-based industrial paint under the same quality will not increase the use cost of customers; The quality of water-based industrial paint can reach or even exceed that of solvent based products. Customers choose water-based industrial paint, and there is no need to transform the coating site. It is also applicable to cold areas in the north

promoting the application in the industrial field becomes the key

although water-based coatings have become more and more popular in the industrial field, the proportion is still much lower than that in the architectural decoration field. For example, in the field of industrial protection, the proportion of water-based coatings is only 1/3; Troubleshooting: replace the oil with suitable viscosity. However, in the field of rail transit, the coating proportion of domestic water-based coatings is lower

Gao Meng, an engineer of CRRC Tangshan Locomotive and rolling stock Co., Ltd., said that rail cars in developed countries in Europe have been coated with water-based paint; The domestic car industry and railway locomotive and freight cars have also achieved water-based paint spraying. For rail cars, only a small number of urban subways have achieved batch water-based coating, and the operation assessment has not been achieved on EMUs. Batch water-based application has not been achieved. He believes that at present, for the coating of rail vehicles, the implementation standard of water-based paint is ambiguous, and no system standard has been established, which restricts the batch use of water-based paint. In addition, the waste gas treatment and waste water treatment of water-based coatings also restrict the development of water-based coatings

"in recent years, environmental protection has developed rapidly in december2017. Containers are required to be environmentally friendly and non-toxic. The vehicles that pull containers are as important as China Europe trains and export vehicles. Therefore, accelerating the promotion of water-based coatings has become an inevitable trend for the development of the industry." Said Wangxingming, deputy chief engineer of CRRC

"ecological environment concerns all mankind. In the 21st century, we should do something valuable and meaningful. Coatings account for 20% of air pollution, of which industrial coatings account for 2/3. Therefore, vigorously solving industrial coatings pollution is the top priority of our work, and environmental protection is important." Huabao (Tianqi indication error is mainly reflected in the following ways: said Zhang Jiao, chairman of Tianjin) coating Co., Ltd

in order to speed up the promotion of water-based coatings, the water-based industrial coating branch of China coating industry association was established. Zhang Jiao, chairman of the water-based industrial coating branch of China Coating Industry Association, said that at the moment of advocating environmental protection and win-win future, upstream and downstream enterprises of water-based industrial coatings should unite to serve end users and create a new development mode of industrial coating. The establishment of the branch is to unite with the R & D, manufacturing and application coating enterprises interested in protecting the ecological environment, build an efficient interactive sharing platform for water-based industrial coating standards, products, technologies, information and services, and accelerate the comprehensive transformation of surface protection and decoration of industrial products to achieve a safe, environmentally friendly and reliable application technology system for water-based industrial coating, Continuously establish and improve various mechanisms and systems beneficial to green manufacturing and healthy development of the branch, and promote the integrated project management mode of environmental protection coating
