摘要
水性阻尼材料制备更简单且绿色环保,其阻尼性能主要取决于基础乳液和填料性能。聚氨酯阻尼材料是目前研究较多和应用较广泛的一种粘弹性材料。为了提高水性聚氨酯阻尼材料的阻尼性能,拓宽其阻尼温域和损耗因子,常采用机械共混、共聚法以及互穿聚合物网络等合成方法。介绍了聚氨酯阻尼材料的降噪机理,总结了水性聚氨酯阻尼材料的合成方法,综述了水性聚氨酯阻尼材料的改性及应用进展。
Waterborne damping materials offer simpler processes and are environmentally friendly.Their damping performance mainly depends on the properties of base emulsion and fillers.Polyurethane damping materials are currently one of most widely researched and applied viscoelastic materials.In order to improve the damping performance of waterborne polyurethane damping materials,broaden their damping temperature range and loss factor,synthesis methods such as mechanical blending,copolymerization,and interpenetrating polymer networks are often used.This article introduced the noise reduction mechanism of polyurethane damping materials,summarized the synthesis methods of waterborne polyurethane damping materials,and reviewed the modification and application progress of waterborne polyurethane damping materials.
