An innovative approach to manufacturing flexible decorative wood veneer using EVA film as adhesive and reinforcing materials

In order to solve the problems of easy cracking and poor flexibility of decorative wood veneer, a simple and efficient approach to manufacturing flexible decorative wood veneer was proposed. Ethylene-vinyl acetate (EVA) film was used as adhesive and reinforcing material for developing EVA film reinforced decorative wood veneer (EVA-RDV). The results showed that EVA film and Manchurian Ash decorative wood veneer could be well composited at 110 degrees C without special treatment. The flexibility was maintained at 4 similar to 6 mm and the transverse tensile strength was 0.99 MPa, which was 412.5% higher than that of the original decorative veneer (DV). It was found that EVA film had better adaptability of veneer moisture content (MC). The cavity proportion was kept within 5%, and the flexibility was little affected. The surface bonding strength was maintained at a stable state of 0.8 similar to 1 MPa (higher than the standard 0.4 MPa). Only 100 degrees C was needed to complete the surface decoration, and the optimal surface bonding strength reached 1.17 MPa. The water resistance of all decorative veneered Medium Density Fiberboards (MDF) met the requirements of indoor use in GEWT 15104-2006.

Automated summary

A simple and efficient approach to manufacturing flexible decorative wood veneer using EVA film as adhesive and reinforcing material was proposed. The EVA film reinforced decorative wood veneer showed improved flexibility and tensile strength compared to the original veneer. The EVA film also exhibited better adaptability to moisture content, and the surface bonding strength met the required standards for indoor use.
