摘　　要：研究了硅烷偶联剂与酚醛树脂改性稻壳粉及填充PVC后对复合材料吸湿性能、力学性能影响。结果表明:用硅烷偶联剂与酚醛树脂复合改性的PVC/稻壳粉体系吸湿量、吸湿后的膨胀率低于单一的硅处理及未处理的复合材料,同时复合改性的PVC/稻壳粉体系力学性能明显优于其它复合材料。The effects of surface treat agent ineluding silane coupling agent （WD-20） and phenol formaldehyde （PF） on the water absorption, mechanical properties of PVC/rice chaff composites were studied. The results showed the values of water absorption and the liner expansion ratio absorbed water of PVC/rice husks composites which modified with com- pound agent including WD-20 and PF was lower than that of the composites with WD-20 and untreated rice husks. At the same time, the mechanical properties of the composites modified with compound agent were more excellent than that of other composites.
