摘要
合成了以聚己内酯为溶剂化链,以四乙烯五胺或多乙烯多胺为锚固基团的“梳形”超分散剂t-ZTPCL和p- ZTPCL,并将其用于聚丙烯／高岭土填料复合材料,研究了分散剂对复合体系力学性能的分散和增强效果。结果表明: ZTPCL对聚丙烯／高岭土复合材料具有明显的增强效果和分散作用。t-ZTPCL质量分数为0．5％～1．0％或p-ZTPCL质量分数为0．5％-2．5％时,复合材料的拉伸强度明显高于未加分散剂的复合材料,部分材料的拉伸强度超过纯PP。摩尔质量为2 000g/mol的p-ZTPCL对复合材料拉伸强度的提高尤为显著,质量分数为2．0％时,复合材料的拉伸强度较纯 PP的提高7．4％,比未加分散剂的提高22．8％。
Hyperdispersants t-ZTPCL and p-ZTPCL, in which poly-ε-caprolactone was used as solvatable chain and teraethylen penta-amine or multi-ethylen multi- amine as fixing group, were synthesized and applied to PP/kaolin clay composite. The effects of the hyperdispersants on the dispersing and reinforcing of the composite were studied. The results showed ZTPCL had obvious reinforcing and dispersing effects on PP/kaolin composite. When the mass perpercentage of t-ZTPCL was 0.5 % ～ 1.0 % or that of p-ZTPCL was 0.5 % ～ 2.5 %, the tensile strength of the composites was obviously higher than that of the composite without hyperdispersant, the tensile strength of partial composite was even higher than that of pure PP. The increase of the tensile strength of the composite by p-ZTPCL （Mn （CTPCL） = 2000） was especially obvious. When the mass perpercentage of p-ZTPCL was 2.0 %, the tensile strength of the composite was 7.4% higher than that of pure PP and 22.8% higher than that of the composite without hyperdispersant.
