This demonstration line was built at the end of last year in Songyuan Bairui Bio-polyol Co., Ltd. of Jilin Province. Dr. Wang Chunpeng of the Institute of Forest Chemistry of the Chinese Academy of Sciences, who participated in the technical research, told reporters that companies that have lignin processing conditions or currently produce phenolic resin adhesives can all be converted to produce lignin-based phenolic resins. At present, the phenol market price is 14,000 yuan/ton, and the price per metric ton of lignin is several thousand yuan. Processing and production of lignin-based phenolic resin is more economical than petroleum-based products. The 20,000-ton/year lignin-based phenolic resin demonstration production line has been successfully put into production, marking China's breakthrough in the efficient preparation of environment-friendly lignin-based phenolic resin adhesives, gradual copolycondensation of lignin-based phenolic resins, and residual control of low free phenol formaldehyde. Technical problems and achieved industrial technical verification.
This project is a technological extension of the biomass-based polymer new material technology and products of the national “863†project hosted by Lin Hua. The technology adopted has completely independent intellectual property rights and is an efficient conversion of plant straw components and deep processing and utilization of lignin resources. Provides new ways and promotes the development of environmentally friendly wood adhesives in the wood-based panel industry.
It is understood that Linhua Institute of Chinese Academy of Forestry and Jilin Song Original Bio-Energy Co., Ltd. have started technical cooperation since 2009 to study the use of high-purity lignin and cellulose as bio-based materials to replace traditional fossil materials and petroleum-derived chemicals. Matsubara Corporation is a high-tech company engaged in research on the biorefining of corn stalk materials and the development of high-performance biomass materials. They use corn stalks as raw materials and adopt integrated patented technology with completely independent intellectual property rights to carry out component separation and directed conversion of straw, while fully utilizing straw hemicellulose to produce butanol, and producing high purity with excellent characteristics. Lignin and cellulose, and raw materials for the production of polyether-based polyols, phenolic resin. The proportion of lignin-substituted phenols in the lignin-based phenolic resins they developed was as high as 60%, and there was no need for complicated purification of lignin.
