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、Al2O3、SiO2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、Al2O3、SiO2对稻草/ABS复合材料增强均优于硅烷偶联剂,其中Al2O3的增强效果最佳。当Al2O3的添加量为5%(Al2O3:ABS)时,Al2O3-稻草/ABS复合材料的拉伸、弯曲及冲击强度分别达到最大值27.719MPa、61.05MPa和26.53kJ/㎡;当无机物添加量为5%(无机物:ABS)时,复合材料的耐水性能表现为:5%Al2O3>5%活性炭>5%SiO2>未添加,与复合材料的力学性能梯度相符;改性剂-稻草/ABS复合材料的流变性能则表现为:5%活性炭>5%Al2O3>5%SiO2>未添加。
Using straw fiber and acrylonitrile-butadiene-styrene (ABS) as raw materials, activated carbon, Al2O3, SiO2 and silane coupling agent were used as modifier to prepare modifier-straw / ABS composites, the enhancement effects of several different reinforcing modifiers and their reinforcing mechanisms were compared. The results show that silane coupling agents have a poor reinforcing effect on straw / ABS composites. Activated carbon, Al2O3, SiO2 are better than silane coupling agents on the straw / ABS composites, Al2O3 is the best. When the content of Al2O3 is 5% (Al2O3: ABS), the tensile, flexural and impact strengths of Al2O3-straw / ABS composites reach the maximum of 27.719MPa, 61.05MPa and 26.53kJ / ㎡, respectively. (5% Al2O3> 5% activated carbon> 5% SiO2) was not added, which was consistent with the gradient of the mechanical properties of the composites. The modifiers - straw / ABS The rheological properties of the composites are as follows: 5% activated carbon> 5% Al2O3> 5% SiO2> not added.
