摘要： Ｎ－环己基 －３－氨丙基甲基二甲氧基硅烷（ＣＡＭＳ）与季戊四醇三丙烯酸酯（ＰＥＴＡ）通过迈克尔加成反应制得可光固化的含硅改性丙烯酸酯，以其为稀释剂加入紫外光固化体系中，通过红外测试表征了固化过程中特征基团的变化，并考察了其对固化膜性能的影响，研究结果表明：随着含硅改性丙烯酸酯加入量的增加，固化膜凝胶率和断裂强度有所下降，但其表面水接触角增大。

Abstract: Aminosilane modified Uv-curable acry lates has been prepared by reacting N-cyclohexyl-Y-aminopropylmethy ldimethoxysilane (CAMS) with pentaerythritol triacrylate (PETA) by Michaeltype addition reaction, which was used as modifying additives for acrylic Uv-curable systems. The change of double bonds during the UV curing process was characterized by means of FT-IR, and the properties of Uv-cured films was studied. With the inerease of aminosilane modified acrylates, the gel content and breaking strength of Uv-cured films decreased, but it's water contact angle increased.
