封端聚羟基硬脂酸酯脂肪胺超分散剂的合成及其应用研究
Synthesis and Application of Terminated Polyhydroxystearate Aliphatic Amine Hyperdispersant
摘要
Abstract
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/m2;When the content of HTPF is 50%,the flexural strength of the composites reaches 80.22 MPa.关键词
