摘要
以TDI、KH550、HEA和环氧氯丙烷为原料，合成了一种新型的聚氨酯丙烯酸杂化树脂，使用红外光谱（FT-IR）和核磁共振（^1H—NMR）对其进行表征，并以杂化树脂为预聚物，制备光固化阻尼涂层，此外对涂层的动态力学性能（DMA）进行了研究，研究结果表明：涂层具有良好的阻尼性能（tanδ≥0.6；T∈10℃～47℃）。
It synthesizes a novel polyurethane acrylic hybrid resin from toluene- 2, 4 - diisocyanate（TDI）, .5 - aminopropyl triethoxysilane（KH550）, hydroxyethyl acrylate（HEA） and epichlorohydrin, Using Fourior-transformed infrared spectroscopy and 1H nuclear magnetic resonance（^1HNMR）, it researches this material characteristics. This hybrid resins can be used as oligomers to prepare damping coatings that is measured by Dynamic mechanical analysis（DMA）. The result shows that the damping coatings have a great damping property（Tanδ≥0.6;T∈10℃～47℃ ）.
