In this paper, the bonding properties of polyvinylchloride (PVC)-based wood-plastic composite (WPC) materials bonded with acrylic adhesive have been studied. The results showed that dry compression shear strength of bonded specimens glued with acrylic adhesive was 6.12 MPa, and reached 58.8% of the strength of the PVC-based WPCs. The results also showed that wet compression shear strength in accordance with Chinese standard GB/T17657 was 0.9 times the dry compression shear strength of 5.48 MPa. In addition, the retention rate of the compression shear strength of the bonded specimens gluing with acrylic adhesive after UV aging for 7 days and 14 days was 69.1 and 66.8%, respectively. The aging was done in accordance with UV-aging test process as given in this paper. The scanning electron microscopy (SEM) analysis of the bonded specimens of PVC-based WPCs showed that the J-39 acrylic adhesive penetrated into the adjacent porous regions of the PVC-based WPC which had resulted from foaming. This penetration enhanced the mechanical interlocking between the substrate and the acrylic adhesive.
