摘　　要：制备了甘蔗渣纤维(BF)/碳酸钙(CaCO_(3))杂化纤维,并研究了杂化纤维的用量比对聚丙烯(PP)性能的影响。结果表明:BF经NaOH丝光处理后,提高了BF与CaCO_(3)的界面相容性,对于复合材料的拉伸强度及抗冲击性能具有一定改善作用;复合材料的热导率随着BF用量的增加而提高;结晶度方面,丝光处理BF复合材料的结晶熔融温度由183.4℃提高至212.8℃,较未丝光处理BF复合材料的结晶度明显提升;SEM结果表明,丝光处理BF,改善了BF与PP的界面相互作用,对于提高材料的综合性能具有较为明显的作用。In this paper,bagasse fiber(BF)/calcium carbonate(CaCO_(3))hybrid fiber was prepared,and the effect of the dosage ratio of hybrid fiber on the properties of polypropylene(PP)was studied.The results show that the interfacial compatibility between BF and CaCO_(3)is improved after BF mercerizing,and the tensile strength and impact resistance of the composites are improved;the thermal conductivity of the composites increases with the increase of BF content.In terms of crystallinity,the crystallization melting temperature of mercerized BF composites increases from 183.4℃to 212.8℃,which is significantly higher than that of the non mercerized BF composites.SEM results show that the interfacial interaction between BF and PP is improved by mercerizing BF,which has a significant effect on improving the comprehensive properties of the material.
