Abstract
The surface of wood/polyethylene (PE) composites were treated by mechanical polishing treatment and coating treatment, and the structure of surface for wood/PE composites before and after treatment was characterized by fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) in this paper. Combined with bonding strength test, the effect of coupling agent KH-560 (2,3-epoxypropoxypropyltrimethoxysilicane) on bonding properties of wood/PE composites was also investigated. The results showed that, the -OH, -C-O- and C=O functional groups were appeared on the treated surface and the surface roughness increased after mechanical polishing treatment and coating treatment, which increased the shear bonding strength for the treated sample significantly. And the coupling agent KH-560 can increase the bonding strength for the composite more significantly due to the co-reaction of epoxy groups which introduced by coupling agent with epoxy resin adhesives.
