On November 5, Chen Yu and Li Nin, experts from the Bamboo Center of the Chinese Academy of For forthics, completed the "Key Technology of Organic Light-Resistant Aging of Bamboo Products" and passed the expert appraisal organized by Zhejiang Technology Brokers Association in Hangzhou.
Results for outdoor bamboo products easy light aging, mold and other issues, carried out organic UV absorbents in bamboo products light-resistant aging function and effect of research, optimize the compounding of benzodiazepine as the main body, acrylic resin, UV curing paint and wood wax oil as the carrier, ethyl acetate and ethanol as a modifier of light-resistant aging
coating
.
visible light transmission and UV shielding of coatings formed by light-resistant aging coatings reached 90% and 99% respectively, greatly slowing down the aging rate of bamboo wood.
the results of the processing costs are low, the process is simple, low toxic environmental protection. At present, this technology has been in Zhejiang Yongyu Bamboo Industry Co., Ltd. and Yanzhu Nanmu Environmental Protection Technology Co. , Ltd. carried out a small-scale promotion and application, enhance the added value of products about 25%, effectively improve the stability of outdoor bamboo products, extend the service life and maintenance cycle of products, by the user's praise.
bamboo wood texture beautiful, strong weight ratio, processability and other advantages, well received by people. In recent years, the Ministry of Industry and Information Technology and the Ministry of Housing and Construction and other departments to vigorously develop biomass green building materials, outdoor bamboo flooring and bamboo wall decoration materials and other outdoor products, bamboo structure buildings are also more and more favored by consumers, outdoor bamboo products a large number of applications to become one of the future development direction of the construction industry. But not treated bamboo products in outdoor applications, vulnerable to ultraviolet radiation to produce light aging, resulting in product discoloration, gloss loss, roughness increase, cracking and coating peeling, etc. , Chen Yu and other research results can improve the performance stability of bamboo products, extend the service life of products, increase product added value.
