Innovative thinking in the application field of water-based polyurethane-special session on synthesis and application of water-based resin

Water-based polyurethane has been widely used for the advantages of low VOC content, low pollution, safe operation and excellent performance. However, compared with solvent-based polyurethane, its cost is relatively high, and there are problems such as long drying time, weather resistance, water resistance, heat resistance, initial stickiness and stability, and relatively poor bonding of low surface energy materials.
In order to exchange the latest progress in water-based polyurethane research and industrialization applications, to promote the development of China's water-based polyurethane industry, the 2018 water-based technology annual meeting on the afternoon of October 23rd, held a "water-based polyurethane" special session, Anhui University Professor Ms. Wu Haiping as Executive Chairman, Beijing University of Chemical Engineering Professor Xia Yuzheng, Chang Chen Weiyu, Senior Researcher of Xing Materials Industry Co., Ltd., Dr. Hong Changfeng of Xuhua Fine Chemical (Nantong) Co., Ltd., Wu Qizhen, Manager of Shanghai Dongfluorochemical Technology Co., Ltd., Sun Xiaoze, Technical Director of Shandong Odeme Polymer Materials Co., Ltd., and Liu Tao, Technical Manager of Shanghai Microspectral Chemical Technology Services Co., Ltd., respectively, made special presentations

Professor Wu Haiping focused on water-based polyurethane scale production, non-isocyanate route polyurethane hydration, renewable resource technology, WPU composite modified/hybridization technology, WPU overspending synthesis and application technology, WPU molecular self-healing technology, re-emulsible water-based UV PUD, self-digesting PUD micro-phospheric technology and other water-based polyurethane technology research hot spots. And in the water-based polyurethane in the hard substrate (wall floor coatings, metal anti-corrosion coatings, plastic coatings, glass ceramic coatings) and soft substrates (leather accessories, fabric coatings, printing coatings, packaging printing coatings, etc.) applications in the market to carry out in-depth exchanges.

Professor Xia Yuzheng outlined vinyl chloride and its vinyl chloride acrylic in his keynote speech on the synthesis and application of vinyl chloride co-polypulestion emulsions. An overview of the development of ester co-polyp, vinyl chloride-acrylic co-polypulfur emulsion, the application advantages and design objectives of vinyl chloride-acrylic co-polypulfur emulsion in plastic composite adhesives, and the application advantages and design objectives of vinyl chloride-acrylic co-polypulfur emulsion in furniture are introduced. Design targets in industrial sponges and wood adhesives, application of vinyl chloride-acrylic co-polypulfur emulsions in industrial coatings, application of vinyl chloride-acrylic co-polyphur emulsions in water-based ultra-thin fireproof coatings, etc., and put forward the application of vinyl chloride and The compositional distribution control of acrylic emulsion polymerization process is still a difficult problem restricting them in the field of industrial coatings and water-based coating adhesives, and it is necessary to master from the depths of theory how its external factors affect the internal structure in order to design the best comprehensive performance products.
Professor Xia Yuzheng made a report on the synthesis and application of vinyl chloride-acrylic co-polypulester emulsions
Through the comparison of water-based polyurethane technology data, the paper analyzes the legal process of cation-type water-based polyurethane-Changxing acetone, and points out that cation-type water-based polyurethane is a water-based resin free of free amine and low VOC, which conforms to the requirements of the present law and environment. Polycarbonate polyols have better solvent resistance than polyester and polyether polyols as cation-type water-based polyurethanes and are suitable for use as anti-fingerprint paint resins.
