摘　　要：为提高木材加工行业中普通胶合板产品的防火、防水和耐磨性能,研究设计了S1、S2和S3三种复合结构的胶合板产品,提出了合理的生产工艺,同时测试了产品的物理力学性能和耐火性能,并进行了技术经济分析。结果表明:三种复合结构胶合板的物理力学性能满足标准要求,其耐火性能远优于普通胶合板。其中,S1结构板的整体物理力学性能较佳;S3结构板的防火性能较佳,其耐火极限约为普通胶合板的1.9倍,且增加的附加成本最低;S2结构板中加入的薄软木板并未起到很好的防火性能,反而使软木板空腔内的空气起到一定的助燃效果,抑制了HPL的防火性,且附加成本最高,综合性能最差。S3结构胶合板由表板层厚度为1 mm的HPL防火板和芯板层厚度为12 mm的普通胶合板组成,具有较好的防火、防水和耐磨性能,且成本较低,具有较高的应用价值和经济效益。In order to improve the fire resistance,water resistance and wear resistance of ordinary plywood products in the wood processing industry,three kinds of plywood products with composite structures of S1,S2 and S3 were designed in this study,and a reasonable production process was proposed.The physical and mechanical properties,fire resistance,and technical and economic analysis of the products were also evaluated.The results showed that the physical mechanics of the three kinds of composite structure plywood could meet the standard requirements,and its fire resistance was far better than that of ordinary plywood.Among them,S1 structural board had the optimum overall physical and mechanical properties.S3 structural board had the optimum fire resistance,which was about 1.9 times higher than the ordinary plywood,and the added cost was the lowest.The thin cork board added to the S2 structural board failed to improve its fire resistance performance.The air in the cork board cavity had a certain combustion-supporting effect,which inhibited the fire resistance of HPL.In addition,the additional cost was the highest,and its comprehensive performance was the worst.The S3 structural plywood product was composed of HPL fireproof board with a thickness of 1 mm in the surface layer and ordinary plywood with a thickness of 12 mm in the core layer,which exhibited excellent fire resistance,water resistance and wear resistance,as well as the lower cost.This product showed higher application value and economic benefits.
