摘要:
使用聚氨酯预聚体(PUP)作为天然高分子材料聚乳酸(PLA)的增韧剂和增容剂,制备了复合材料.力学性能测试结果表明:PUP的添加量质量分数仅为1%时,所得材料的伸长率就可以达到33.9%; 随着PUP质量分数的增加,改性后的PLA复合材料的断裂伸长率和冲击强度随之升高,并且将之运用于3D打印过程中,也表现出较好的效果.通过XRD和DSC结果表明,改性得到的复合材料的结晶性能良好.
Abstract:
This article uses polyurethane prepolymer(PUP)as a natural polymer material polylactic acid(PLA)toughener and compatibilizer to prepare a composite material.The mechanical property test results showed that the elongation of the obtained material(PPLA)can reach by 33.9% when the mass fraction of the additional amount of PUP was only 1%.and the elongation at break as well as impact strength of the modified PLA composite enhanced with the increase of PUP content.The obtained PPLA material also showed good effects in the 3D printing process.The crystallization property of the PPLA was also excellent through the results of XRD and DSC.
