To remove VOC from coatings, it is necessary to speed up product upgrading.
"the abuse of dichloroethane will cause many serious consequences, and even lead to a more serious catastrophic event than 'Sanlu milk powder', which has become an unbearable burden for enterprises." Based on this consensus of the coating industry, bards, RT mart, zhanchen, Clivia, garberry, Huilong and Huicong coatings signed the Beijing Declaration on furniture paint in Beijing last week to promote the whole industry chain to reject the use of highly toxic solvents, commit to developing environmentally friendly products, strive to reduce consumption, energy conservation and emission reduction, achieve green production, procurement and spread the concept of green consumptionGuowei, general manager of marketing center of zhanchen coating group, said that solvent is an important raw material for coating. For a long time, the former does not require its casting project to introduce world-class free casting production line and die forging hydraulic production line. Building exterior wall insulation materials "should not be lower than grade B2 (organic materials)" can be completely replaced. In the future, the key to the development of coating enterprises is to gradually replace toxic and harmful solvents with low toxic solvents. At present, DBE solvent (dimethyl succinate, dimethyl glutarate and dimethyl adipate mixed solvent), DMC (dimethyl carbonate), SEC butyl acetate and other low toxic solvents are widely used and are good choices. "In the long run, gradually reducing the amount of solvent is the development direction of the coating industry. Solvent based coating products will be transformed into water-based and UV curing products. However, this is a long process. It is not only necessary to strengthen the development of production process and equipment, but also the test faced by coating enterprises with high cost and more strict use technology." The traditional method of using single 1 material to increase the wall thickness to achieve thermal insulation can no longer adapt to energy conservation and environmental protection. Guo Wei said that traditional solvent based coatings have long been listed as dangerous chemicals, and the volatile organic compounds (VOCs) contained therein pose a threat to human health. In the past two years, the active and prosperous furniture paint market has led to changes in the pattern of the paint industry, and the polarization trend of furniture paint manufacturers has accelerated significantly. In this case, in order to survive and seize the market, a small number of furniture paint manufacturers began to use some low-cost and highly toxic pendulum as raw material substitutes. For example, dichloroethane is very harmful to human body, but because the price is only 1/3 of butyl solvent, it has become the first choice for some manufacturers
it is understood that at present, there are no clear laws and regulations in China to make clear provisions on the use of dichloroethane in paint solvents, and the environmental protection and safety of furniture paint mainly depend on enterprise self-discipline. In this context, the enterprises participating in the signing of the contract promise to resolutely not produce or use toxic and harmful solvents and curing agents, unite more forces to resist these products, and call on the whole industry and the government to jointly inspect the terminal small diluent curing agent plants under the supervision of relevant government departments, so as to speed up the product upgrading of the whole industry and develop towards UV and water-based coatings
