【摘要】 以甲基封端环己烷单胺型氨基硅油（MCAPS）与1,6-己二醇二丙烯酸酯（HDDA）为原料通过迈克尔加成反应合成了含硅改性丙烯酸酯,用红外、核磁和凝胶色谱对产物进行了表征。以其为稀释剂加入紫外光固化体系中,少量的加入即能显著的改变固化膜的表面性能:含硅改性丙烯酸酯的质量分数由0.0%增加到0.5%时,光固化膜表面水接触角由42°增加到92°,表面电阻率由9.8×10¹⁴Ω增加到17.1×10¹⁴Ω,表面光泽度由117.6°下降到100.8°。更多还原

【Abstract】 A new type of polyorganosiloxane acrylate was synthesized by reacting methyl end capping cyclohexylamine type amido modified polyorganosiloxane(MCAPS) with hexanediol diacrylate (HDDA) by Michael addition reaction.The product was characterized by means of FTIR, 1HNMR and GPC measurements,and it was used as modifying additives for acrylic UV-curable systems.Notwithstanding its very low concentration,the polyorganosiloxane acrylate caused a dramatic change of the surface properties of the UV-cured films.When the mass content of polyorganosiloxane acrylate changes from 0.0%to 0.5%,the contact angle of UV-cured films increases from 42°to 92°and the surface resistance increases from 9.8×1014Ωto 17.1×1014Ω,but the gloss of UV-cured films decreases from 117.6°to 100.8°.更多还原
