摘要
通过熔融共混的方法制备了丁苯热塑性弹性体/聚苯乙烯/剑麻纤维(SBS/PS/SF)复合材料。采用SBS/PS=70/30的配比,通过改变剑麻纤维用量,研究SBS/PS/SF复合材料的力学性能、热性能及熔体流动速率。结果表明:随着剑麻纤维用量的增加,SBS/PS/SF复合材料的弹性模量和弯曲强度都有所增加;熔体流动速率呈减小趋势;拉伸强度、断裂应变、屈服应变和冲击强度先上升后下降;SBS/PS/SF复合材料的维卡软化点随着剑麻纤维的加入也有着不同程度的下降。
Styrene butadiene thermoplastic elastomer/Polystyrene/sisal fiber（SBS/PS/SF） composite was prepared by melt blending method. By fixing the ratio of SBS/PS at 70/30, and changing the content of sisal fiber, the mechanical properties and thermal properties of SBS/PS/SF composites were researched. The results indicate that： with the increase of sisal fiber content, the elastic modulus and bending strength of the composites increase. The melting flow rate decreases, and the tensile strength, breaking strains, yield strain and impact strength increase first and then decrease. The vicat softening temperature of SBS/PS/SF composite decreases with the addition of sisal fiber.
