罗浮锥薄木饰面胶合板生产工艺研究

Study on Decorative Technology of Castanopsis faberi Veneer

  • 摘要: 为提升罗浮锥木材的高附加值,以桉木胶合板为基材,基于正交试验设计,研究施胶量与热压工艺参数(温度、时间和压力)对罗浮锥饰面板的含水率、浸渍剥离和表面胶合强度的影响,探明罗浮锥饰面板的优化生产工艺,明确不同类型清漆(硝基清漆、水性清漆和聚氨酯清漆)涂饰工艺对罗浮锥饰面板的色差和漆膜理化性能的影响。结果表明:罗浮锥饰面板的含水率、浸渍剥离强度及表面胶合强度均符合国标要求,其最佳施胶量为120 g/m2,最佳热压温度、热压时间和热压压力分别为160 ℃、60 s和0.3 MPa;其经硝基清漆涂饰样品的漆膜抗冲击、耐磨、附着力等性能均符合家具表面漆膜理化性能的相关国标要求,经聚氨酯清漆涂饰样品的漆膜抗冲击性不符合家具表面漆膜理化性能相关国标要求,经水性清漆涂饰样品的漆膜耐磨性不符合家具表面漆膜理化性能相关国标要求,但具有最好的附着力和抗冲击性能。罗浮锥木材纹理美观,胶合、热压和涂饰性能优良,作为高端饰面板开发潜力大。

     

    Abstract: In order to promote the high value utilization of Castanopsis faberi plantation wood, this paper taked eucalyptus plywood as the base material, studied the influence of glue and hot pressing technology (glue spread, hot pressing temperature, hot pressing time and hot pressing pressure) on the moisture content, dipping peeling and surface bonding strength of the C. faberi veneer through orthogonal test method, so as to obtained the production technology of the C. faberi veneer. Besides, the effects of different kinds of varnishes (nitrocellulose varnish, waterborne varnish and polyurethane varnish) on the color difference parameters and the physicochemical properties of the paint film of the C. faberi veneer were investigated. The results showed that the moisture content, immersion peeling strength and surface bonding strength of the C. faberi veneer met the requirements of the national standard. The optimal hot pressing process was 120 g/m2 of glue, 160 ℃ of hot pressing temperature, 60 s of hot pressing time and 0.3 MPa of hot pressing pressure. The impact resistance, abrasion resistance, adhesion and other properties of nitrocellulose varnish and coating film met the requirements of the national standard. The impact resistance of polyurethane varnish coating film did not meet the requirements of the national standard. The abrasion resistance of water-based varnish coating film did not meet the requirements of the national standard, but it had the best adhesion and impact resistance. The Castanopsis faberi Hance wood had beautiful texture, excellent bonding, hot pressing and finishing performance, and had great potential for high-end decorative panel development.
