摘要
使用硅烷偶联剂表面处理的木粉(MW)和未改性木粉(UW)填充不饱和聚酯树脂(UPR)制备了复合材料。研究了表面改性处理和木粉粒径对复合材料力学强度的影响。结果表明,相对于未改性的木粉,用硅烷偶联剂处理的木粉对不饱和聚酯树脂有更强的增强作用,添加量为20(wt)%的MW/UPR复合材料的拉伸强度比纯UPR提高74.4%,抗冲强度比纯UPR增加36.1%;木粉的粒径对MW/UPR复合材料力学性能的影响较为复杂。
Composites were prepared with unsaturated polyester resin（UPR） and woodflours which were modified by silicane coupling agent（MW） and unmodified（UW）.The effects of modified method and woodflour particle size on the mechanical properties of composites were studied.Comparing with neat UPR,the tensile strength and impact strength of MW/UPR increased by 74.4% and 36.1% while the composite was containing 20（wt）% MW.The relateship between woodflour particle size and mechanical strength was intricacy.
