摘要
利用回收聚丙烯和木纤维为原料制备木塑复合材料,分析聚丙烯加量、补强剂种类、产品密度和纤维形态等对材料性能的影响。结果表明:增大聚丙烯比例能大幅提高物理力学性能;补强剂能明显改善所测性能;板材密度对提高抗弯性能最有效;中粗纤维制备的复合材料抗弯性能最好,但内结合强度相对最低。本研究范围内最佳工艺参数为:聚丙烯40%、PAPI 2%,板材密度1.05 g/cm3和采用中粗纤维。
A kind of recycled polypropylene was selected as a raw material to make composite with wood fibers. This study evaluated the effect of polypropylene content, additives, density, and fiber size on the performance of the wood-plastic composite. The result showed that increasing polypropylene content improved the overall board performance. Adding additional binders to the wood-plastic composite manufacturing process reinforced the fiber-bonding which could in turn enhance the board properties. Increasing the product＇s density was the most effective way to improve bending properties. Fiber geometry was also found to affect board bending properties. It was recommended the following process parameters： 40 %recycled polypropylene, 2 % PAPI additive need to be used in making the wood-plastic composite with board density of 1.05 g/cm^3.
