噪声污染严重影响人们的生活质量，阻尼涂料作为一种有效的减振降噪材料，正向着高阻尼性能、宽温域、功能化的方向发展，水性阻尼涂料的电绝缘性使材料表面产生的静电积累，限制了阻尼涂料在特定环境中的应用。文章选用聚苯胺改性水性聚氨酯/丙烯酸酯树脂（WPUA-PANI）作为基础树脂，绢云母作为阻尼填料，加入其他助剂，制备了一系列具有防静电性能的水性阻尼涂料。研究了绢云母与基础树脂质量比对涂料结构与性能的影响。结果表明：所制备的涂料均为假塑性流体，具有较好的防流挂性。当绢云母与基础树脂质量比为30/70时，其水接触角和电阻率分别为110.9°和7.24×10⁴ Ω·cm，有效阻尼温域值最大为122 ℃，较基础树脂得到明显提升。涂料具有良好的阻尼性、防静电性和耐水、耐溶剂性能。

Noise pollution seriously affects people's quality of life. As an effective vibration and noise reduction material, damping coatings are developing in the direction of high damping performance, wide temperature range and functionalization. The electrical insulation of water-based damping coatings makes static electricity accumulate on the surface of materials, which limits the application of damping coatings in specific environments. Polyaniline modified water-based polyurethane/acrylate resin (WPUA-PANI) was selected as the base resin, sericite as the damping filler, and other additives were added to prepare a series of water-based damping coatings with antistatic properties. The influence of the mass ratio of sericite to base resin on the structure and properties of coatings was studied. The results show that the coatings prepared are pseudoplastic fluids and have good anti-sagging properties. When the mass ratio of sericite to base resin is 30/70, the water contact angle and resistivity are 110.9° and 7.24×10⁴ Ω·cm, respectively, and the maximum effective damping temperature range is 122 ℃, which is obviously higher than that of the base resin. The coating has good damping property, antistatic property, water resistance, and solvent resistance.
