以木薯厌氧渣为填料,聚乳酸(PLA)为基体,采用模压成型制备了PLA/木薯厌氧渣复合材料,探究了木薯渣填充量、偶联剂添加量、机械球磨时间、温度、转速及模压温度、压力、时间等因素对复合材料力学性能的影响。结果表明,偶联剂占木薯渣质量的2%,木薯渣填充量为10%,球磨时间为30 min,球磨温度为60℃,球磨转速为300 r/min,模压时间为6 min,模压温度为190℃,模压压力为10 MPa时,复合材料的弯曲强度为63.108 MPa,拉伸强度为44.155 MPa,力学性能较好。以PLA与木薯厌氧渣为主要原料制备复合材料,既能有效降低复合材料的生产成本又能使复合材料保持较好的力学性能,避免了废弃木薯渣对环境的污染,且为实现生物质资源的高值化利用提供理论依据。 Using cassava anaerobic residue as filler and polylactic acid (PLA) as matrix, PLA / cassava anaerobic slag composites were prepared by compression molding. The effects of filling amount of cassava residue, coupling agent, milling time, temperature, And molding temperature, pressure, time and other factors on the mechanical properties of composites. The results showed that the coupling agent accounted for 2% of the mass of cassava residues, the filling amount of cassava residues was 10%, the milling time was 30 min, the milling temperature was 60 ℃, the milling speed was 300 r / min, the molding time was 6 min, When the molding temperature is 190 ℃ and the molding pressure is 10 MPa, the bending strength of the composites is 63.108 MPa, the tensile strength is 44.155 MPa, and the mechanical properties are better. PLA and cassava anaerobic slag as the main raw material for the preparation of composite materials, both to effectively reduce the composite material production costs but also to maintain good mechanical properties of the composite material to avoid the waste of cassava residue on the environment pollution, and to achieve biomass The high value of resources to provide a theoretical basis.
