Abstract

Abstract

The use of fabrics to decorate wood plastic composites (WPC) in a variety of styles can greatly improve the practical value of WPC. In this study, a new decorative fabric veneer technique was developed, in which a thermoplastic polymer was laid on the surface of the decorative fabric. This enabled the thermoplastic polymer to be in direct contact with the hot platen, thus shortening the time that the decorative fabric was exposed to high temperatures. Moreover, the heat-melted polymer fused with the polymer on the surface of the wood-plastic substrate through the decorative fabric, which served to fix and protect the decorative fabric. In this paper, the effects of hot-pressing temperature (140℃, 160℃ and 180℃), wood-plastic ratio in the substrate (6∶4, 7∶3 and 8∶2) and the type of polymer (high density polyethylene, low density polyethylene and polylactic acid (PLA)) on the properties, such as surface bonding strength, decorative effect and mechanical properties of the decorative wood flour/high-density polyethylene (WF/HDPE) composites, were investigated. The changes in the properties of WF/HDPE composites and fabrics were analyzed and characterized by FTIR and SEM. The results show that the molten polymer is able to pass through the fiber voids of the decorative fabric and fuses well with the wood-plastic substrate. The surface of the produced decorative composite material is smooth and even. The effects of hot pressing temperature, substrate wood-plastic ratio and surface polymer type were comprehensive analyzed. When the hot pressing temperature is 160℃, wood-plastic ratio is 7∶3, the mechanical strength of the WF/HDPE composite substrate with the surface layer of the fabric decorated with PLA is the best. Its surface bonding strength is up to 3.64 MPa and the bending strength reaches 82.19 MPa.
