"Key Technology of Industrialization of Ten Thousand Tons of Enma Resin Wood Adhesive" Passes Scientific and Technological Achievement Appraisal

2024Year3Month1On the 1st, the key technology for the industrialization of 10,000-ton olefinic resin wood adhesive jointly developed by Xinyuan Chemical (Shandong) Co., Ltd., Beijing University of Chemical Technology and Tsinghua University passed the achievement appraisal organized by the China Petroleum and Chemical Industry Federation in Beijing. The meeting was headed by Academician Chen Xuesi of Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Director of Ecological Industry Division I of Industrial Development Planning Institute of State Forestry and Grassland Administration, Secretary General of National Aldehyde-free Wood-based Panel Innovation Alliance Zhang Zhongtao, General Manager of Science and Technology Research Center of Sinochem Division Ding Kehong, Deputy General Manager of Sinochemical Science and Technology Research Co., Ltd, dong Xia, a researcher at the Institute of Chemistry of the Chinese Academy of Sciences, served as a member.

Miao Xiaoliang, general manager of Xinyuan Chemical (Shandong) Co., Ltd., Xie Lefu, chief engineer, academician Yang Wantai and team members of Beijing University of Chemical Technology, relevant technicians and project cooperation units, Xu Fujian, dean of the School of Materials Science and Engineering, and Guo Xindong, executive vice president of the Institute of Science and Technology Development, attended the meeting.

China is the world's wood-based panel production, consumption power, annual output accounted for the world's50%Above. Adhesive is an important raw material in the production of wood-based panels,2022Output Value of Adhesives for Wood-based Panels in China750More than 100 million yuan, of which the amount of urea-formaldehyde resin (including modification) accounted for more91%. However, the use of urea-formaldehyde resin in the production, transportation and use of wood-based panels have the problem of formaldehyde release, a serious threat to human health. With the increasing awareness of environmental protection, formaldehyde emission control has become an urgent problem in the wood-based panel industry.

In addition, the current global olefin industry chain annual by-product.1More than 100 million tonsC4~C9and other fractions, which contain a large number of olefin components (500010,000 tons or more); in primary gasoline/Liquefied gas and coal tar distillates also contain huge amounts of mixed olefins. These mixed olefins are difficult to separate, high cost, and low utilization efficiency. Except for a small amount of petroleum resin raw materials, most of them are directly burned as low-value fuels, causing great waste of resources. If this part of the mixed olefin resources can be turned into treasure, it can not only solve the cost problem of aldehyde-free adhesives, but also realize the high-value utilization of mixed olefin resources, which is of great significance to the current national oil reduction and increase strategy, the conversion of new energy to replace fossil energy, and the realization of the "double carbon" goal.

Based on the above background, led by Academician Yang Wantai of Beijing University of Chemical Technology, the relevant technical teams of Xinyuan Chemical (Shandong) Co., Ltd., Beijing University of Chemical Technology, and Tsinghua University developed enma resin adhesive, and in Xinyuan Chemical (Shandong) Co., Ltd. Through industrial tests, the company finally developed a complete set of enma resin industrial preparation technology with independent intellectual property rights, built a 10,000-ton device, with annual output1Ten thousand tons of enma resin adhesive solid products and.0.3The production capacity of ten thousand tons of enma resin adhesive liquid products, and a number of authorized patents. Enma resin adhesive has been applied by many users, with stable and reliable quality, good market feedback, and significant social and economic benefits. Enma resin adhesive has the characteristics of water-soluble, formaldehyde-free, wide source of raw materials, low cost of glue, basically the same glue process as urea-formaldehyde resin and excellent bonding performance, showing great potential to replace traditional urea-formaldehyde resin.

After listening to the research report and work report of the results, reviewing the relevant technical data, and after questioning and discussion, the appraisal expert committee agreed that the product of enma resin wood adhesive was the first in the world, and the overall technology of the achievement was at the international leading level. It was agreed to pass the appraisal and suggested to further increase the popularization and application of the results.
