摘　　要：探讨了偶联剂、热压工艺对竹材玻纤布复合生产集装箱底板材力学性能的影响,分析了偶联剂种类、用量,以及热压压力、热压时间、热压温度对竹材玻纤布复合生产的集装箱底板产品静曲强度、弹性模量、耐磨性、内胶合强度、浸渍剥离等性能的影响。通过正交试验,得出优化的热压工艺为:1偶联剂R1和R2均适合作玻纤布表面处理的偶联剂。2偶联剂需用酒精稀释,较佳的稀释配比为1:2或者1:3。3热压压力2.6 MPa、热压温度150℃、热压时间1.1min/mm。4热压压力对竹材玻纤布复合集装箱底板产品物理力学性能指标的影响均不显著;热压温度对竹材玻纤布复合集装箱底板的纵向MOE和内结合强度影响显著,对竹材玻纤布复合集装箱底板的横向MOE影响较显著;热压时间对竹材玻纤布复合集装箱底板内结合强度影响较显著。The effect of coupling agent and hot-pressing technology on the mechanical properties of bamboo/glass fiber fabric container bottom plates is discussed and the effect of the type and amount of coupling agents, hot pressing time and hot pressing temperature on the static bending strength, modulus of elasticity, abrasion resistance and inner bonding strength impregnated stripped performance of container bottom plates produced from bamboo/glass fiber fabric. The optimized hot pressing process obtained through orthogonal experiments is： （1）R1 and R2 are suitable as a coupling agent for glass fiber fabric surface treatment. （2）Coupling agents need to be diluted with alcohol, with the optimum dilution ratio of 1：2 or 1：3. （3） Hot pressing pressure is 2.6 MPa, temperature 150℃, time 1.1 min/mm. （4）The effect of hot pressing pressure on the physical mechanical performance indicators of optimum bamboo/glass fiber fabric container bottom plate products is not significant but the effect on the transverse MOE of bamboo/glass fiber fabric container bottom plates is significant, and the effect of hot pressing time on the inner bonding strength of bamboo/glass fiber fabric container bottom plates is very significant.
