Abstract

In the present work plywood has been coated with polypropylene rather than the traditional coating material, thermoset. A modified extrusion coating process was applied with the aim of achieving adequate adhesion between the plywood and the thermoplastic. The adhesion was maximised by optimising the coating process, modifying the coating itself, and treating the plywood surface. The coating device was developed and processing conditions were optimised to improve the adhesion. Polypropylene was modified with numerous adhesives and coupling agents; in addition various different treatments were used for the plywood. The adhesion was tested with a peel test using an ISO 8510-1 standard. According to the peel test results high melt temperature and low pressure during the extrusion process improved the adhesion. Maleic acid anhydride modified polypropylene was the most effective coupling agent. Some surface treatments of the plywood also had a significant influence on adhesion.
