摘要 以聚氨酯丙烯酸酯(PUA)、1,6-己二醇二丙烯酸酯(HDDA)、季戊四醇三丙烯酸酯(PETA)、甲基丙烯酸六氟丁酯(G02)、十七氟癸基三甲氧基硅烷(F17-TMS)、光引发剂11732-羟基-2-甲基-1-苯基丙酮(1173)、长链烷基改性纳米SiO2(C8H17-SiO2)为原料,在紫外光的照射下制备了一种纳米杂化防水涂层。通过红外光谱(FT-IR)、场发射扫面电镜(SEM),接触角测量仪和热重分析仪(TGA)等对产物结构、性能进行了测试。结果表明:改性纳米SiO2可以在光固化涂层中较均匀分散,加入改性纳米SiO2可以明显改善涂层的疏水性、硬度、耐冲击性、耐水性,但对涂层热稳定性影响不大。

Abstract: A nano hybrid waterproof coating has been prepared under UV radiation by using polyurethane acrylate, 1,6-hexanediol diacrylate (HDDA), pentaerythritol triacryl(PETA), hexafluorobutyl methacrylate, heptadeca fluoro decyl trimethoxysilane (F17-TMS), photoinitiator 1173 (2-hydroxy-2-methyl-1-phenyl acetone) and long chain alkyl modified nano silica (C8H17-SiO2) as the raw materials. The structure and properties of the product are tested by infrared spectroscopy (FT-IR), field emission scanning electron microscopy, contact angle measurement and thermogravimetric analyzer. The results show that the modified nano silica can be uniformly dispersed in the photo-curable coating, and the addition of modified nano silica can significantly improve the hydrophobicity, hardness, impact resistance, water resistance,whereas, has little effect on the thermal stability of the coating.
Key words:  UV curing    polyurethane acrylate    nano silica
