摘要
实验以甲基封端环己烷单胺型氨基硅油(MCAPS)、二丙二醇二丙烯酸酯(DPGDA)为原料,经迈克尔加成反应,合成含硅改性丙烯酸酯。结果表明,其最佳合成条件为:V(DPGDA):V(MCAPS)=2:1,70℃反应24 h。含硅改性丙烯酸酯的质量分数由0增加到0.5%时,光固化膜表面水接触角由42.5°增至91.8°,表面电阻率由9.8×10^(14)Ω增加到17.3×10^(14)Ω,表面光泽度由117.6°下降到100.5°。
A new type of polyorganosiloxane acrylate was synthesized by reacting methyl end capping cyclohexylamine type amido modified polyorganosiloxane （MCAPS） with dipropylene glycol diacrylate （DPGDA） by Michael addition reaction. The optimum conditions for the synthesis of polyorganosiloxane acrylate were. V（DPGDA） ： V（MCAPS）=2 ： 1, reaction temperature 70 ℃ and reaction time 24 h. The product was characterized FTIR,^1H NMR and GPC measurements, and was used as modifying additives for acrylic UV-curable systems. A very low concentration of the polyorganosiloxane acrylate caused a dramatic change of the surface properties of the UV-cured films. When the mass content of polyorganosiloxane acrylate changed from 0 to 0.5%, the contact angle of UV-cured films increased from 42.5° to 91.8° and the surface resistance increased from 9.8×10^14Ω to 17. 3 × 10^14 Ω, but the gloss of UV-cured films decreased from 117.6° to 100.5°.
