Biomass energy-saving alternative to hazardous materials in the preparation of polyurethane insulation materials technology award

By the Chinese Academy of Forestry of the innovation team led by researcher Zhou Yonghong complete the " harmful alternative biomass feedstock preparation of polyurethane insulation materials key energy-saving technology development" project won the 2013 Jiangsu Province Science and Technology Progress Award.Wholesale masking tape

The project consists of the national high-tech industrial development projects , 948 projects supported by the State Forestry Administration , China's biomass compared for energy-saving insulation materials production of polyurethane products and technologies in a single process , product quality and petrochemical products have a larger gap between the poor flame retardancy the reaction of secondary pollution, production runs and poor stability and controllability to waste oil and turpentine substitute other non- edible natural oils phthalic anhydride, phthalic acid and other petrochemical raw materials, design and development of quality indicators have reached the level of raw petrochemical products energy-saving insulation materials based polyurethane foam material products , Masking tapehas made a number of innovative achievements : First, the development of oil -based polyester polyol reaction continuous production plant , created a new type of oil -based polyester polyether polyols can replace all petrochemical polyols, without affecting the insulation and dimensional stability properties of polyurethane products. Two pine research group developed a new design of the polyester-polyether polyol and preparation techniques. First using a dibasic acid polymerized rosin , phenol-formaldehyde condensation of dibasic acids and small molecules polyhydric alcohol rosin -based development of new polyester-polyether polyols , polyester composition material deposited overcome always fatal disadvantage of poor stability . Third, the study of rosin for rigid polyurethane foam polyisocyanate create technology. By DA addition reaction of rosin , amidation and reaction of the amide with oxalyl chloride acid triacyl fumaropimaric isocyanates, avoiding the traditional phosgene , mild reaction conditions. Fourth, innovative biomass-based polyurethane foam flame retardant technology , to meet the national standards for the preparation of compound flame retardant polyurethane foam flame retardant insulation materials .Washi tape

Projects for different sources of raw materials, design and development of polyurethane foam insulation products have different physical and chemical properties and application performance , build the largest biomass polyester polyol production lines ( 30,000 T / year) and the first domestic oil base polyester polyol continuous production line ( 20,000 T / year) , the results extended to Jiangsu, Fujian and other provinces in recent years , sales of 410 million yuan new , new profit 48 million yuan , successfully achieved industrial applications . Item 12 authorized patents , utility model patents, published 25 papers . Promote the use of the project can save oil resources , reduce environmental pollution , and achieved remarkable economic, social and ecological benefits.Sellotape
