Effect of High Temperature Treatment on Properties of Wood/Plastic Plywood
Poplar veneers were treated in the oven under different temperatures before high density polyethylene(HDPE)film was applied to them to manufacture plywood.The effects of treating temperatures on the physical-mechanical properties of wood-plastic plywood were investigated and the mechanism was studied by infrared spectroscopy and contact angle analysis.Results showed that the hydrophilicity decreased when poplar veneers were treated between 130and 200 ℃,which effectively improved interfacial compatibility with HDPE films and greatly improved the shear strength and water resistance of the plywood.However,because of the depolymerization of the veneers,both plywood MOR and MOE decreased after treatment.The optimum comprehensive properties of the plywood could be obtained when poplar veneers were treated at 160℃in the oven.
