纳米SiO2改性苯基缩水甘油醚丙烯酸酯的紫外光固化性能研究
Study on UV-curing Properties of Phenyl Glycidyl Ether Acrylate Modified by Nano-SiO2
摘要
Abstract
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-SiO2 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-SiO2 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-SiO2 in a appropriate amount can improve the tensile strength,elongation and impact strength of the UV-curing materials.关键词
