摘　　要：通过缩聚反应制备聚12-羟基硬脂酸酯,将软脂酸、3-二甲氨基丙胺与聚12-羟基硬脂酸酯反应,生成封端聚羟基硬脂酸酯脂肪胺(HTPF)超分散剂。采用红外光谱、核磁共振氢谱对产物结构进行表征。通过沉降实验与扫描电镜分析HTPF对于炭黑的分散效果。将HTPF加入ABS/炭黑色母粒中,研究HTPF的用量对ABS/炭黑色母粒流变性能以及力学性能的影响。结果表明:相较纯色母粒,随着HTPF用量的增加,复合材料的损耗模量和储能模量逐渐降低,并且复合材料出现剪切变稀行为。随着HTPF用量的增加,复合材料的力学性能逐渐提升。当HTPF用量为40%时,复合材料的拉伸强度、冲击强度达到最大,为45.9 MPa和8.54 kJ/m^(2);当HTPF用量为50%时,复合材料的弯曲强度达到80.22 MPa。Poly(12-hydroxystearate) was prepared by polycondensation.Palmitic acid,3-dimethylaminopropylamine and poly(12-hydroxystearate) were reacted to form a terminated polyhydroxystearate aliphatic amine(HTPF) hyperdispersant.The structure of the product was characterized by IR and 1H NMR.The dispersion effect of HTPF on carbon black was analyzed by sedimentation experiment and scanning electron microscope.HTPF was added into ABS/carbon black masterbatch,and the effects of the amount of HTPF on the rheological and mechanical properties of ABS/carbon black masterbatch were studied.The results show that the loss modulus and storage modulus of the composites decrease gradually with the increase of HTPF content compared with the pure masterbatch,and the composites appear shear thinning behavior.With the increase of HTPF content,the mechanical properties of the composites gradually improved.When the content of HTPF is 40%,the tensile strength and impact strength of the composite reach the maximum of 45.9 MPa and 8.54 kJ/m^(2);When the content of HTPF is 50%,the flexural strength of the composites reaches 80.22 MPa.
