It is understood that the current national CPPCC Standing Committee, Jiangxi CPPCC Vice Chairman, the MDC Jiangxi Provincial Committee Committee Chen Qinghua said, from the national current measures to deal with haze and haze, the state must put the water-based coatings industry in the priority of development industry, strengthen support in the policy, in the layout of rational design, in order to promote the entire coating industry transformation and upgrade, from the source to curb the pollution caused by organic pollutants.
At present, the measures to deal with foggy weather in China are mainly from the three aspects of motor vehicle exhaust emissions, industrial enterprise exhaust emissions, dust removal. Chen Qinghua believes that like paint, and pesticides produced in the process of production and use of organic pollutants will cause air pollution, but whether from the policy, or from the specific measures, the government has not paid enough attention to the treatment of organic pollutant emissions, and did not take appropriate measures to reduce the emissions of organic pollutants.
In fact, the application of coatings is very extensive, involving the development of national economy in various fields, such as indoor and outdoor buildings, furniture, vehicles, medical equipment, toys and so on, can not be separated from the use of paint. However, more than 80% of China's use of oily coatings, is based on a variety of organic solvents such as benzene, ketones as a dispersing medium. Some studies have shown that oily coatings are the second largest source of pollution in modern society, the composition of the coating is very complex, containing a large number of organic compounds in the use of the process, to the air release a large number of formaldehyde, benzene, vinyl chloride and other harmful gases, large-scale use of oily paint is also caused by the current haze and PM2.5 One of the important causes of pollution.
Chen Qinghua In response to this problem, in recent years, with oily coatings in the water-based coating industry began to rise, water-based coatings to water as a dispersing medium, to avoid or reduce the traditional oily coatings in the use of organic solvents, is a kind of environmentally friendly coatings. At the same time, water-based coatings with good adaptability, non-toxic without stimulation, burning and other characteristics, can completely eliminate the harmful effects of organic solvents on the human body, low-carbon environmental protection, green energy-saving, with strong security, has a traditional oily paint incomparable advantage. At present, water-based coatings in Europe and the United States and other developed countries are widely used, the market share in more than 60%, in Europe, water-based products up to 80%; in the automotive coatings field, more than 80% of the car primer, more than 50% of the flash topcoat has been basically water-based. With the further development of science and technology, water-based coatings are expected to become the mainstream of the global coatings industry development. However, the domestic lack of adequate understanding of the industry, coupled with the cost, technology, research and development of talent shortage, although belong to the green products, but in the paint market only accounted for less than 20% of the share.
