2017, is the key to the development of environmental protection industry, people's awareness of environmental protection has been generally improved for the painting industry, in the 'oil to change the water' policy continues to enter the implementation of the background, the traditional solvent-based paint into Capacity out of the period, the development of modern water paint production capacity is the future trend of the development of the industry, China's water-based paint market prospects.
Traditional solvent-based paint hazards
The study shows that the paint is both a haze source and a healthy eraser. The important reason for the haze weather is PM2.5, which accounts for 30% of the total vehicle exhaust emissions and 21% of the VOC (volatile organic compound) , Other natural power generation, industrial production and other combustion products in the process of emissions accounted for 49% of the residue, and recently reported that about 18% of VOC emissions from solvent-based paint emissions generated.
Paint with oil and coal from the extraction of organic solvents from the dilution treatment, not only need to consume fossil energy, organic solvents also contain a lot of benzene, toluene, xylene, formaldehyde and other toxic and hazardous substances, the volatile period of up to ten years Traditional paints often use a large number of toxic and harmful volatile organic solvents as diluents, and some products also use a curing agent containing free TDI, resulting in a lot of air pollution, studies have shown that long-term inhalation of these solvents and curing agent volatile gas will lead to Aplastic anemia, leukemia, tuberculosis, pleurisy and other serious diseases.
Around the 'oil to water' policy into the implementation period
Water-based paint is water as a dispersion medium, in layman's terms, is the water-based paint is water to paint, water spray in the spraying and drying process is the evaporation of water, its VOC emissions are very small. Solvent-based paint in the paint and dry The process of a large number of thinner, that is, organic solvents to volatilize, produce a lot of VOC. Data show that water-based paint VOC emissions than solvent-based coatings can be reduced by 60% to 70% .Therefore, water-based paint more and more people of all ages The
June 2015, Beijing issued a furniture emission standards, the standard pointed out that since January 1, 2017, the Beijing furniture manufacturing industry will be a complete ban on the use of oil paint that paint spray, the Beijing area of all the oil paint For the water-based paint.
October 10, 2016, 'Shenzhen standard' one of the Shenzhen Special Economic Zone technical specifications "furniture products and raw and auxiliary materials in the limited material" by the Shenzhen Municipal People's Government review and approval of the implementation, the provisions pointed out that since May 1, 2017 , The Shenzhen area will be a complete ban on solvent-based paint and solvent-based adhesive use.
In March this year, Xi'an released the "2017" iron fist haze road to defend the blue sky '1 + 1 +9' combination program, "the program clearly stipulated since April, prohibit high volatile toxic and harmful thinner in the market On the sales, at the same time, to strengthen the paint industry in the volatile organic matter content control efforts.
Breakthrough core technology is the key to the development of waterborne paint market
From today's global development trend of the paint industry can be seen, China has become the world's largest producer of paint and consumer power, but in promoting the popularization of environmentally friendly coatings is far behind Europe and the United States.Stat statistics show that the European environmental paint penetration rate The average has reached 80% - 90%, while China's Beijing, Shanghai and other first-tier cities, the penetration rate of environmentally friendly coatings less than 25% .It can be seen, more environmentally friendly water-based paint there is a huge market potential to be tapped.With the Chinese paint The development of the industry is increasingly strong, the water-based paint market is bound to be the overall trend of the paint industry driven by a share of the current water-based paint market, the urgent need for a number of research and development capabilities, financial and technical support industry elite to lead the water- Healthy development of the road ahead.
Waterborne polymer technology through the introduction of hydrophilic groups in the polyurethane segment, and through the strong dispersion of polyurethane particles dispersed in water to form water-based polyurethane. Water-based polyurethane technology Water-based polyurethane resin preparation and application of water-based science and technology is the core technology , But also the basis of the project, water-based days have a number of polysiloxane diol patented technology, the production of water-based polyurethane water resistance is good; after the chain extension, and then extended chain technology, solvent-free preparation method can make waterborne polyurethane Molecular weight reached a million high, the product strength of 60MPa, can fully reflect the advantages of polyurethane performance; the same time, the traditional water-based polyurethane production using intermittent production, and water-based use of semi-continuous production, efficiency, , And has the first domestic 100,000-ton water-based polyurethane production line. In short, the patented technology raw materials, advanced synthetic technology, suitable for large-scale production line is the core of water-based advantages.
Water-based paint market prospects
Data show that in 2016 China's water-based paint demand is about 1.89 million tons, accounting for less than 10% of the proportion of the coating industry, with the water-based paint in steel, furniture, containers and other areas to accelerate, is expected to 2022, China's water-based paint market Demand will reach 6.34 million tons, the compound growth rate of more than 20%. 'Oil to water' policy introduced to the water-based paint business has brought good, I believe that the popularity of water-based coatings and applications will achieve long-term progress.
