卫浴家具用竹刨花板的工艺研究

Research on Production Process of Bamboo Particleboard for Bathroom Furniture

通过正交试验L_(9)(3^(4))方案,考察了竹刨花的比例、表层刨花添加剂用量、三聚氰胺改性脲醛树脂(MUF)的物质的量比F∶(M+U)对刨花板主要性能的影响,根据优化出的工艺组合制备浸渍胶膜纸饰面竹刨花板,并探讨其作为卫浴家具用板的性能。研究结果表明,当竹刨花100%、表层刨花添加剂用量5 kg/m^(3)、MUF的物质的量比为0.89时,生产的竹刨花板性能较佳,静曲强度、内胶合强度、24 h吸水厚度膨胀率均达到GB/T 4897—2015《刨花板》中P6型的要求,甲醛释放量达到JIS A 5908—2022 Particleboards中F☆☆☆☆标准,其作为基材制备的浸渍胶膜纸饰面竹刨花板性能达到GB/T 15102—2017《浸渍胶膜纸饰面纤维板和刨花板》要求,浸渍剥离性能达到GB 24977—2010《卫浴家具》的要求,可做卫浴家具用板。

The orthogonal experiment L_(9)(3^(4))scheme was used to investigate the effects of the proportion of bamboo shavings,the amount of surface shavings additive,and the substance ratio(F:M+U)of melamine modified urea formaldehyde resin(MUF)on the main properties of bamboo particleboard.Based on the optimized process,the decorative bamboo particleboard with paper impregnated thermosetting resins was prepared,and its performance as a board for bathroom furniture was explored.The results showed that when bamboo shavings were 100%,the amount of surface shavings additive was 5 kg/m^(3) and the content ratio of MUF was 0.89,the performance of the bamboo particleboard was better.The static bending strength,internal bonding strength and 24 hours water absorption thickness expansion rate met the requirements of P6 type in GB/T 4897—2015 Particleboard,and the formaldehyde release met the F☆☆☆☆standard in JIS A 5908—2022 Particleboards,The performance of the decorative bamboo particleboard with paper impregnated thermosetting resins met the requirements of GB/T 15102—2017 Surface decorated fiberboard and particleboard with paper impregnated thermosetting resins,and the impregnation peeling performance met the requirements of GB 24977—2010 Bathroom Furniture.It showed the bamboo particleboard could be used to made bathroom furniture.
