以稻草纤维及丙烯腈-丁二烯-苯乙烯(ABS)为原料,分别以活性炭、Al_2O_3、SiO_2和硅烷偶联剂为增强改性剂,通过混炼-模压工艺制备了改性剂-稻草/ABS复合材料,对比研究了几种不同增强改性剂的增强效果及其增强机制。结果表明:硅烷偶联剂对稻草/ABS复合材料的增强效果较差,活性炭、Al_2O_3和SiO_2对稻草/ABS复合材料的增强均优于硅烷偶联剂,其中Al_2O_3的增强效果最佳。当Al_2O_3的添加量(Al_2O_3∶ABS质量比)为5%时,Al_2O_3-稻草/ABS复合材料的拉伸、弯曲及冲击强度分别达到最大值27.719 MPa、61.05 MPa和26.53 kJ/m~2;当无机物添加量(无机物∶ABS质量比)为5%时,复合材料的耐水性能表现为:5% Al_2...

The rice straw fiber and acrylonitrile-butadiene-styrene(ABS)were used for the raw materials. The acticarbon, Al2O3, SiO2 and silane coupling agent were used for modifiers, respectively. The modifier-straw fiber/ABS composites were prepared via mixing molding process. The reinforcing effect and its strengthening mechanism of several different modifiers were compared. The results show that the effect of silane coupling agent on the straw fiber/ABS composites is poor, and the strengthening of the acticarbon, Al2O3 and SiO2 on the composite is bet...
