Development of Waterborne Resin Industry in China

Water-based resin production enterprises are mostly concentrated in East China and South China, while Zhejiang, Jiangsu, Shandong, Shanghai and other places are the main provinces in East China, while Guangdong Province is the main province for the distribution of enterprises in South China. In general, there are many problems in the production of water-based resin, such as the small number of enterprises and the need to improve the process. From the demand point of view, the main downstream industry of water-based resin is water-based coatings, at present, the proportion of water-based coatings in China still has a large room for improvement, water-based coatings due to high cost, part of the coating performance is inferior to solvent-based coatings resulting in solvent-based coatings is still a high market share of a class, short-term water-based coatings can not completely replace solvent-based coatings.

The global production of water-based coatings is expected to reach 32.71 million tons in 2022, and the market is good.

Analysis of the main reasons for 1. growth: 1, construction and automotive applications driven (1) the construction industry is the main reason for the growth of water-based coatings this part of the application accounted for 86.5 of the total market. In the next six years, new construction and renovation projects in the Asia-Pacific and Middle East will be the main driving force for the growth of the water-based coatings market, as water-based coatings are widely used in indoor and outdoor, door, decorative materials and building exterior painting. (2) The growth of the automotive industry promotes the demand for water-based coatings. In addition, the continuous growth of automobile production in China, India, Thailand, Indonesia and Mexico also promotes the demand for water-based coatings. Automotive OEM is pre-

The proportion of VOC coating products reached 60% in 2018

工业和信息化部和财政部2016年7月8日联合发文《工业和信息化部财政部关于印发重点行业挥发性有机物削减行动计划的通知》(工信部联节〔2016〕217号)，宣布为贯彻落实《中国制造2025》（国发〔2015〕28号）和《大气污染防治行动计划》（国发〔2013〕37号），加快推进落实绿色制造工程实施指南，推进促进重点行业挥发性有机物(VOC)削减，提升工业绿色发展水平，改善大气环境质量，提升制造业绿色化水平，工信部组织编制了《重点行业挥发性有机物削减行动计划》，并向各省、自治区、直辖市及计划单列市、新疆生产建设兵团工业和信息化主管部门、财政厅（局）、有关行业协会印发，计划实施期为2016-2018年。   据中国化工学会水性技术应用专委会了解，根据该《计划》制定的主要目标，到2018年低（无）VOC涂料产品比例要达到60%！《计划》指出，工业是VOC排放的重点领域，排放量占总排放量的50%以上，工业排放源复杂，主要涉及生产、使用、储存和运输等诸多环节，其中：石油炼制与石油化工、涂料、油墨、胶粘剂、农药、汽车、包装印刷、橡胶制品、合成革、家具、制鞋等行业VOC排放量占工业排放总量的80%以上。工业行业VOC排放具有强度大、浓度高、污染物种类多等特点，回收再利用难度大、成本高，是工业领域VOC削减的重点。   目前，大气污染防治形势严峻，加快重点行业VOC削减，对推动工业绿色发展，促进大气环境质量改善，保障人体健康具有重要意义。   为此，《计划》提出的思路为：以技术进步为主线，坚持源头削减、过程控制为重点，兼顾末端治理的全过程防治理念，发挥企业主体作用，加强政策支持引导，推动企业实施原料替代和清洁生产技术改造、提升清洁生产水平，促进行业绿色转型升级。   而《计划》制定的主要目标为：到2018年工业行业VOC排放量比2015年削减330万吨以上，减少苯、甲苯、二甲苯、二甲基甲酰胺（DMF)等溶剂、助剂使用量20%以上，低（无）VOC的绿色农药制剂、涂料、油墨、胶粘剂和轮胎产品比例分别达到70%、60%、70%、85%和40%以上。   涂料行业的主要任务为：重点推广水性涂料、粉末涂料、高固体分涂料、无溶剂涂料、辐射固化涂料（UV涂料）等绿色涂料产品。《计划》指出，要实施工艺技术改造工程，其中家具行业中，木质家具制造企业推广应用VOC含量低的水性漆，鼓励“油改水”工艺和设备改造；软体家具企业推广应用水性胶粘剂。汽车行业中，涂装环节推进水性涂料、高固体份涂料替代溶剂型涂料，推广静电喷涂、淋涂、辊涂、浸涂等高效涂装工艺和先进智能化涂装设备。   此外，《计划》还提出要实施回收及综合治理工程，鼓励企业实施生产过程密闭化、连续化、自动化技术改造，建立密闭式负压废气收集系统，并与生产过程同步运行。采取密闭式作业，并配备高效的溶剂回收和废气降解系统。根据不同行业VOC排放浓度、成分，选择催化燃烧、蓄热燃烧、吸附、生物法、冷凝收集净化、电子焚烧、臭氧氧化除臭、等离子处理、光催化等针对性强、治理效果明显的处理技术对含VOC废气进行处理处置。为保障《计划》提出的各项目标顺利实现，《计划》还提出要加大政策引导支持力度，各级工业和信息化主管部门应充分利用专项建设基金、绿色信贷等资金渠道，支持工业企业实施VOC削减技术改造，对符合条件的VOC削减技术改造项目优先给予支持。有关地方财政部门可将符合规定的重点行业VOC削减技术改造项目纳入中央大气污染防治专项资金支持范围。此外，工信部还将组织制定VOC削减重点行业相关绿色设计产品评价标准，开展绿色设计产品评价工作，发布绿色设计产品名录，推动行业绿色发展。加强标准宣贯，树立设计示范企业，引领企业不断提升清洁生产技术水平。

Environmentally friendly low VOC coatings will usher in a "warm spring"

It is understood that during the 13th Five-Year Plan period, the country will strengthen the control of the total amount of volatile organic compounds (VOC) and carry out coordinated emission reduction of nitrogen oxides and VOC. All companies in the seven major occupations of industrial painting, including cars, ships, containers, furniture, construction machinery, steel structure and coil making, must implement VOC induction management. Environmentally friendly low VOC coatings will usher in the "warm spring" of development, and the water-based industrial coatings will catch up with architectural coatings and appear to go hand in hand. Development Status of Waterborne Industrial Coatings Waterborne industrial coatings are mainly used in automobiles, railway vehicles, bridges, pipelines, steel structures, containers and other fields

Type and Development Trend of Environmental Protection Metal Table Front Treatment Technology

For a long time, if some workpieces of household electrical appliances have higher requirements for anti-corrosion, the current common solution is to use a chemical and electrochemical reaction to form a phosphate chemical conversion film in the metal coating pretreatment process (this process is referred to as phosphating, and the phosphate conversion film formed is called phosphating film), it protects metal products such as home appliances together with post-coating to ensure that problems such as rust will not occur for 10 years or more. Although phosphating has excellent corrosion resistance and other properties, it also produces many problems, such as high energy consumption, serious pollution, containing harmful heavy metals, difficult wastewater treatment, easy

Green development into the mainstream, paint enterprises to enter the environmental protection

Now, environmental issues have become the object of global concern, and as we all know, paint and other home building materials enterprises as a traditional manufacturing industry, naturally also inevitably need to face the problem of environmental pollution. Now the consumer's consumption concept is also advancing with the times, the demand for environmental protection is becoming more and more obvious, paint companies must take environmental protection as an important direction of their own development. Green competition will become the main competition model The current low-carbon development model based on low energy consumption, low pollution and low emissions and the development of emerging energy industries have become one of the hot topics of people all over the world. For paint companies, the implementation of low-carbon technologies will also be
