以竹纤维和聚乳酸（PLA）为原料,乙二醇、甘油、聚乙二醇400、尿素、甲酰胺和柠檬酸酯为增塑剂,通过熔融共混法制备了竹纤维/PLA可降解复合材料。探讨了一元增塑、二元复合增塑和三元复合增塑对竹纤维/PLA复合材料拉伸强度、抗弯强度、断裂伸长率和耐水性能的影响。试验结果表明,不同增塑剂对竹纤维/PLA复合材料的增塑效果不同,甘油增塑复合材料的拉伸强度和抗弯强度最大,甲酰胺增塑复合材料的断裂伸长率最大,柠檬酸酯增塑复合材料的耐水性能最优。二元复合增塑具有协同增塑效果,甘油/柠檬酸脂复合增塑竹纤维/PLA复合材料的拉伸强度和抗弯强度最大,乙二醇/甲酰胺复合增塑竹纤维/PLA复合材料的断...

By using bamboo fiber and polylactic acid ( PLA) as raw materials, and ethylene glycol, glycerin, polyeth-ylene glycol 400, urea, formamide and citric acid ester as plasticizers, bamboo fiber/PLA biodegradable composites were prepared by the melt blending method. The effects of unitary plasticization, 2-element compound plasticization and 3-element compound plasticization on the tensile strength, flexural strength, elongation at break and water resist-ance of bamboo fiber/PLA composites were investigated. The experimental results showed that the plasticizing effects of different plasticizers o...
