Method for recycling urea-formaldehyde (UF) and raw materials from wood-based panel, and use thereof
Patent number: 11958942Abstract: The present disclosure provides a method for recycling urea-formaldehyde (UF) from a wood-based panel. In the present disclosure, the UF is depolymerized by an ultrasonic treatment, and depolymerized UF can be reused for UF manufacture and wood-based panel production. The recycled and treated UF can be repeatedly used in wood-based panel manufacture without affecting performances of the wood-based panel. UF-glued wood-based panels can be recycled, and a recycled wood-based panel raw material can replace at least 50% of a non-recycled wood-based raw material for particle board production without affecting performances of the wood-based panel.Type: GrantFiled: April 10, 2023Date of Patent: April 16, 2024Assignee: Southwest Forestry UniversityInventors: Hui Wan, An Mao, Hong Lei, Xiaojian Zhou, Zhi Li, Long Yang, Linkun Xie, Guanben Du -

A pH value of the adhesive solution is controlled to be 9-11. A solid content is 40-60%. An adhesive amount applied to the palm bark by the resin adhesive solution is 800-1500 g/m2. Odd number of layers (three or more layers) of palm barks that are impregnated by the resin adhesive solution and are hot-pressed to the composite material. Hot-pressed parameters are as follows: the temperature is 150-180° C. the unit pressure is 0.8-1.5 MPa, and the time is 10-30 s/mm.Type: GrantFiled: December 30, 2019Date of Patent: September 6, 2022Assignee: SOUTHWEST FORESTRY UNIVERSITYInventors: Xiaojian Zhou, Guanben Du, Jun Zhang, Jinxing Li, Bin Li, Taohong Li
