纳米SiO_2改性苯基缩水甘油醚丙烯酸酯的紫外光固化性能研究（英文）
|
摘要
以苯基缩水甘油醚(PGE)和丙烯酸(AA)为原料,三苯基膦为催化剂,4-甲氧基苯酚为抑制剂,合成了一种新型光敏预聚物苯基缩水甘油醚丙烯酸酯(PGEA)。然后用十六烷基三甲基溴化铵处理纳米SiO_2,并用硅烷偶联剂γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH-570)进行表面改性,并加入到预聚物PGEA中,制成紫外纳米复合涂层。用扫描电子显微镜(SEM)发现涂层含量小于5%时,改性纳米SiO_2的分散效果较好。用扫描原子力显微镜(AFM)观察到固化膜表面光滑。而适量的改性纳米SiO_2可以提高紫外光固化材料的拉伸强度、伸长率和冲击强度。
A new photosensitive prepolymer phenyl glycidyl ether acrylate(PGEA)was synthesized from phenyl glycidyl ether(PGE)and acrylic acid(AA)as raw materials,triphenylphosphine as the catalyst and 4-methoxy phenol as the inhibitor. Then, nano-SiO_2 was treated with cetyltrimethylammonium bromide and surface-modified with silane coupling agent γ-methacryloxypropyltrimethoxysilane(KH-570),and added to the synthetic prepolymer PGEA,formulated as UV nanocomposite coating.By scanning electron microscopy(SEM)observation,it was found that the dispersion of modified nano-SiO_2 was better when its content of the coating was less than 5%.Scanning atomic force microscope(AFM)observation showed that the surface of curing film was smooth.And the modified nano-SiO_2 in a appropriate amount can improve the tensile strength,elongation and impact strength of the UV-curing materials.
