according to the data released by Dean Xiu, the situation of haze pollution in China is serious, and ozone pollution is not optimistic. With the continuous development of the national economy, the state also puts forward higher requirements for environmental quality. The overall requirements of the national "13th five year plan" for the prevention and control of VOCs Pollution show that the prevention and control of VOCs Pollution should focus on improving the ambient air quality, focus on key regions and industries, focus on reducing VOCs with strong reactivity, promote the coordinated emission reduction of VOCs and NOx, strengthen the emission control of new pollutants, and implement the management of pollutant discharge permits for fixed pollution sources. During the 13th Five Year Plan period, the national key industries such as chemical industry, packaging and printing, and industrial coating implemented the strategy of "key projects and staggered peak production" to control key pollutants

after introducing the national requirements for VOCs Pollution Prevention and control of industrial coating/printing, President Xiu explained in detail the national requirements for VOCs emission control of container, automobile, furniture, ship, engineering machinery, steel structure, coil coating and other industrial coatings, and provided reference suggestions for the comprehensive prevention and control of VOCs in the packaging and printing industry. At the same time, the environmental protection policies of Guangdong Province, Jiangsu Province, Zhejiang Province and Shanghai were interpreted respectively. Guangdong Province requires to increase the emission reduction of key active components of VOCs such as aromatic hydrocarbons, olefins, alkynes, aldehydes and ketones with strong activity. The coating industry should focus on promoting green products such as water-based coatings, powder coatings, high solid coatings and radiation curing coatings; Jiangsu Province requires the full use of low VOCs content water-based coatings and adhesives in the container, transportation, mechanical equipment, wood-based panel, furniture, shipbuilding and other industries by the end of 2017; Zhejiang Province requires that by 2020, the total emission of VOCs in the province will be reduced by more than 20% compared with that in 2015. This is the initial "flight test" point project, and the emission of VOCs will be reduced by more than 255000 tons; Shanghai requires that by 2020, the production sites of solvent based coatings and inks should be halved compared with 2015. In addition, the development trend of relevant national/local standards, such as the standard for VOC content limits of architectural coatings and adhesives, and the emission standard of air pollutants in the coating, ink and adhesive industry have been interpreted in detail

songkunlun, engineer of Beijing GAOMENG new materials Co., Ltd., brought the keynote speech "Application of waterborne polyurethane and epoxy acrylic acid in waterborne industrial paint". Song Gong elaborated the theme from three aspects: environmental protection, enterprise and application. With the enhancement of the people's awareness of environmental protection, the number of environmental protection reports in 2016 was 263009, nearly 180 times that in 2014; There are more and more water-based academic researches related to environmental protection, and more and more enterprises in water-based industries, which jointly promote the development of water-based coatings. At present, industrial coatings occupy "half" of the industry, but the water-based rate is very few. With the promotion of environmental protection law and the development of the industry, the water-based coating in China is showing a situation of contention among hundreds of schools of thought

in order to help enterprises solve the problems caused by film formation and drying, songgong compared the performance of acrylic lotion, epoxy ester and epoxy modified acrylic acid. The results showed that the drying performance, film performance and reproducibility of the product were improved by using epoxy modified acrylic resin, The tolerance to the construction environment will be greatly improved. Songgong believes that epoxy acrylic resin has both the drying performance of lotion products and the performance of epoxy ester resin. Its poor weather resistance can be improved by grafting some monomers that can improve weather resistance or physically mixing some high weather resistant resins, which can solve some pain points that have troubled customers for a long time; Due to its star molecular structure, waterborne polyurethane dispersion has excellent performance in paint film resistance, substrate adhesion, etc. at the same time, it can also be used as an auxiliary resin to improve the performance of other resins

Dr. Shujun Shu, technical R & D Manager and senior engineer of Dow Chemical (China) Investment Co., Ltd., shared Dow Chemical water-based metal corrosion protection solutions at the forum. Taking the overview of waterborne metal anticorrosive coatings as the starting point, he focused on the resin solutions and additives selection of waterborne metal anticorrosive coatings. According to the introduction, the main components of waterborne coatings are water, lotion, additives, powders and solvents. If classified by function, the raw materials such as lotion, rheological additives and dispersants are better than surfactants (wetting agents) Film forming additives are more used in the research and development of water-based coatings. Now, Shandong Sida hi tech machinery equipment Co., Ltd. will introduce the experimental method and production of a fatigue testing machine

among the various water-based resin solutions recommended by President Shu, the economic highlight - maincotemhg-100 is eye-catching. Its resin parameters are excellent, and it has excellent gloss, corrosion resistance and excellent early water resistance. In a word, It is a new product specially developed for solvent based alkyd replacement. According to the standards for water-based anti-corrosion coatings for steel structures and maincot engineering plastics, etmhg-100 can be divided into two categories: general engineering plastics and special engineering plastics. Based on the coating supporting system of maincotemhg-100 lotion, President beam recommended that it be used in the standards for water-based anti-corrosion coatings for steel structures C2 (H) and C3 (L). In addition, the hybrid star maincottmaeh-20 is also the resin solution that President beam focused on in this speech. According to the physical property parameters and test results published on site, hybrid star has excellent weather resistance and strong powdering resistance: the traditional aqueous epoxy system has been powdered for 6 months, while the aqueous two-component hybrid system aeh-20 system has not been powdered for 17 months

if raw material grinding is an important process of coating production, the coating grinder is the most important carrier of this process.
