摘要：为获取红锥饰面板优化的生产工艺,促进红锥人工林木材的高值化利用,本文以桉木胶合板为基材,通过正交试验研究了施胶与热压工艺(施胶量、热压温度、热压时间和热压压力)对红锥饰面板含水率、浸渍剥离性能和表面胶合强度的影响。在此基础上,探究了不同种类清漆(硝基清漆、水性清漆和聚氨酯清漆)涂饰工艺对红锥饰面板的色差参数和漆膜理化性能(抗冲击性、耐磨性、附着力、铅笔硬度)的影响。结果表明:红锥饰面板的含水率、浸渍剥离性能及表面胶合强度均符合国标要求;最佳的施胶量、热压温度、热压时间和热压压力分别为120 g/m2、180℃、60 s和0.4 MPa;经硝基清漆和聚氨酯清漆涂饰处理红锥饰面板的漆膜抗冲击、耐磨、附着力等性能均符合国标要求,水性清漆涂饰的漆膜耐磨性不符合国标要求,但其具有最佳的附着力和抗冲击性能。红锥木材作为高端饰面板的开发潜力大。
In order to obtain optimized production technology of Castanopsis hystrix veneer,promote the high value utilization of Castanopsis hystrix plantation wood.In this study,Eucalyptus plywood was taken as the research object,the influences of glue and hot pressing process(glue spread,hot pressing temperature,hot pressing time and hot pressing pressure)on the moisture content,dipping peeling property and surface bonding strength of the Castanopsis hystrix veneer were investigated through orthogonal test method.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(resistance to impact,wearability,adhesion,pencil hardness)of the veneer were also investigated.The results showed that the moisture content,dipping peeling property and surface bonding strength of the veneer could meet the requirements of the national standard.The optimal hot pressing process was 120 g/m2 of glue,180℃of hot pressing temperature,60 s of hot pressing time,and 0.4 MPa of hot pressing pressure.The impact resistance,abrasion resistance,and adhesion of the paint film coated with nitrocellulose varnish and polyurethane varnish could meet the requirements of the national standard.However,the abrasion resistance of the paint film coated with water-based varnish could not meet the requirements of the national standard,but it had the best adhesion and impact resistance.The Castanopsis hystrix wood has great development potential.
