摘要/Abstract

摘要： 用一步法制备了受阻酚AO-80改性的聚酯/聚醚胺型聚氨酯/聚(甲基丙烯酸甲酯-苯乙烯)互穿聚合物网络(PU/P(MMA-St)IPN)。通过热失重分析仪、动态力学分析以及扫描电子显微镜对IPN 材料的热稳定性、阻尼性能和微观结构形态进行了表征。研究结果表明: AO-80可以提高PU与P(MMA-St)的相容性,从而有效拓宽阻尼温域;当聚氨酯中聚酯/聚醚胺=80/20,w(AO-80)= 20phr,PU/P(MMA-St)=70/30 时,所得IPN 材料的阻尼性能最佳。

Abstract: Hindered phenol AO-80-modified polyester/polyether amine type polyurethane/poly(methyl methacrylate- styrene) interpenetrating polymer networks (PU/P(MMA-St) IPN) was prepared by one-step way. Through the thermo-gravimetric analyzer, dynamic mechanics analysis and scanning electron microscope to IPN material, the thermal stability, damping performance and microstructure morphology of this material were characterized. The results of the study show that, AO-80 can improve the compatibility of the PU and P (MMA-St), thus effectively broaden the damping temperature range. When polyester/polyether amine is 80/20, w (AO-80) is 20 phr, PU/P (MMA-St) is 70/30, the damping properties of the IPN material is best.

Key words: polyurethane, polymethyl methacrylate, polystyrene, hindered phenols, interpenetrating polymer network, damping properties
