| 摘 要： | 丙烯酸酯类树脂具备高分子材料特有的优异阻尼特性,同时又具有很好的稳定性和耐候性,该研究以含有极性基团的内烯酸酯乳液为基础,通过2种乳液的共混及添加受阻酚类有机小分子等制备水性阻尼涂料,考察了有机小分子的氢键作用对阻尼涂料阻尼性能的影响.通过动态力学分析(DMA)发现,功能性有机小分子可以提高乳液的玻璃化转变温度和阻尼性能,同时可以调节2种共混乳液间的相容性,从而有效拓宽共混样品的高阻尼温域.红外分析发现,增加样品中有机小分子的含量,样品中的氢键含量会相应提高.

| Abstract: | Acrylic resin is an ideal damping coating matrix with excellent damping characteristics,good stability and weather resistance.Waterborne damping coatings were prepared based on acrylate mulsion with excellent damping performance by adding hindered phenol compound into the single and blend emulsions.The influence of hydrogen bonding of small organic molecules on the damping performnuce was investigated.The DMA test results showed that the addition of the small organic molecules(SOM) compound shifted the Tg o... |
