参照国家标准GB/T 7124-2008《胶粘剂拉伸剪切强度的测定（刚性材料对刚性材料）》检测PVC/木粉复合材料胶合试件的拉伸剪切强度,发现：PVC/木粉复合材料胶合试件的断裂均发生在粘接区域外的复合材料本身,因而无法比较胶黏剂的粘接强度。为了能比较胶黏剂胶接接头的粘接强度,实验中将GB/T 7124-2008中规定的试件的厚度从1.6 mm加大至4mm。实验结果表明：采用环氧树脂粘接的PVC/木粉复合材料的拉伸剪切强度值高于用J-39丙烯酸酯胶黏剂粘接的复合材料的拉伸剪切强度。

In this paper,the tensile shear strengths of PVC wood-plastic composites with two adhesives were tested according to Chinese standard GB / T 7124-2008（Adhesives-Determination of tensile lap-shear strength of rigid-to-rigid bonded assemblies）.It was found that glue-blocks bonded with epoxy adhesive and J-39 Acrylic adhesive were broken all at the bonding materials itself outside the bonding region,leading to bonding strength not being compared between two adhesives.In order to compare bonding strength of glued joints with two adhesives,the thickness of specimen consisted of glued joints will be increased to 4 mm from 1.6 mm.The results showed that tensile shear strength of PVC wood-plastic composites glued joints with epoxy adhesive is higher than that of acrylic adhesive.
