Objective To develop a new type of wood-plastic composite material. Methods The formula and the preparation method of a new type of wood-plastic composite material were reasonably designed by comparison test and verification test. Results The optimal formula of a new type of wood- plastic composite material and the most optimized preparation method and technological parameters ( plate thickness: 12 mm, heating temperature of material mixing: 80 ~ 90 ℃ , temperature of cooling water: 3 ~ 8 ℃ ) were determined. Conclusion The new type of wood-plastic composite material was anti-static, fire-proofing, moisture proof, water proof, insect preventing, mould proof, and had strong adhesive force, high corrosion resistance,high strength, good tenacity, high aging resistance, good buffering effects, smooth surface, light weight , good woody performance , with no pollution and low cost, and is therefore suitable for printing marks.
