木塑窗角的熔焊注塑复合连接试验

摘要

Composite connection , combined with welding and injection technology , was applied to corner connection of wood-plastic composite windows .Wood-plastic composites windows were made up of 60%of wood-flour ( WF) , 36%of polyethy-lene ( PE) and 4%of maleic anhydride grafted PE ( MAPE) .Composite connection tests included welding connection and injection connection .Compared with different connection strengths under different welding temperatures , the optimal pa-rameters can be chosen in injection connection .The connection status was analyzed by Moldflow .The welding-injection composite connection can be applied to solve the corner connection problems of the WPC windows with enough connection strength.%应用熔焊技术和注塑成型技术相结合的复合连接技术，对木塑窗进行了角部连接试验。木塑窗型材成分为60％的木粉（WF）、36％的聚乙烯（PE）和4％的马来酸酐接枝聚乙烯（MAPE）。复合连接试验由熔焊连接和注塑连接组成。通过对比不同焊接温度下的熔焊连接强度，选出进行注塑连接的最佳工艺参数，并应用Mold-flow软件分析了复合连接的状况。研究结果表明熔焊注塑复合连接技术可以应用于木塑窗的角部连接问题，并且具有足够的强度。
