To improve the properties of titanium dioxide particles and realise their firm anchorage in blue light curing film, three modified titanium dioxide particles were prepared by grafting 3‐(trimethoxysilyl)propyl methacrylate, 3‐aminopropyltriethoxysilane and hexadecyltrimethoxysilane. The surface changes of titanium dioxide particles after modification were characterised. The dispersion stability, photo‐polymerisation, rheological and mechanical properties of modified titanium dioxide blue light curing inks were investigated. Results showed that compared with native titanium dioxide, modified titanium dioxide particles were more appropriate for blue light curing ink. The particle sizes of the three modified titanium dioxide particles became smaller, their surfaces exhibited hydrophobicity, and the viscosity of the modified titanium dioxide inks decreased slightly. Of the three modified titanium dioxide particles, 3‐(trimethoxysilyl)propyl methacrylate‐ and hexadecyltrimethoxysilane‐modified titanium dioxide particles exhibited better dispersion stability in blue light curing ink. In particular, 3‐(trimethoxysilyl)propyl methacrylate‐modified titanium dioxide blue light curing ink showed the best photo‐polymerisation and mechanical properties, which indicated the participation of the pigment grafted by double bonds in the blue light curable polymerisation. Using modified titanium dioxide in blue light curing ink, the dry/wet rubbing fastness of the printed fabrics improved.

硅烷偶联剂接枝的二氧化钛及其在蓝光固化油墨中的应用

为了改善二氧化钛颗粒的性能并使其牢固地锚固在蓝光固化膜中,通过接枝甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯,3-氨基丙基三乙氧基硅烷和十六烷基三甲氧基硅烷制备了三种改性的二氧化钛颗粒。表征了改性后的二氧化钛颗粒的表面变化。研究了改性二氧化钛蓝光固化油墨的分散稳定性,光聚合,流变和机械性能。结果表明,与天然二氧化钛相比,改性二氧化钛颗粒更适合蓝光固化油墨。这三种改性二氧化钛颗粒的粒径变小,其表面显示出疏水性,改性二氧化钛油墨的粘度略有下降。在这三种改性的二氧化钛颗粒中,甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯和十六烷基三甲氧基硅烷改性的二氧化钛颗粒在蓝光固化油墨中表现出更好的分散稳定性。特别是,甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯改性的二氧化钛蓝光固化油墨显示出最佳的光聚合和机械性能,这表明通过双键接枝的颜料参与了可蓝光固化的聚合反应。在蓝光固化油墨中使用改性的二氧化钛,可以改善印花织物的干/湿摩擦牢度。甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯和十六烷基三甲氧基硅烷改性的二氧化钛颗粒在蓝光固化油墨中表现出更好的分散稳定性。特别是,甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯改性的二氧化钛蓝光固化油墨显示出最佳的光聚合和机械性能,这表明通过双键接枝的颜料参与了可蓝光固化的聚合反应。在蓝光固化油墨中使用改性的二氧化钛,可以改善印花织物的干/湿摩擦牢度。甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯和十六烷基三甲氧基硅烷改性的二氧化钛颗粒在蓝光固化油墨中表现出更好的分散稳定性。特别是,甲基丙烯酸3-(三甲氧基甲硅烷基)丙酯改性的二氧化钛蓝光固化油墨显示出最佳的光聚合和机械性能,这表明通过双键接枝的颜料参与了可蓝光固化的聚合反应。在蓝光固化油墨中使用改性的二氧化钛,可以改善印花织物的干/湿摩擦牢度。这表明通过双键接枝的颜料参与了可蓝光固化的聚合反应。在蓝光固化油墨中使用改性的二氧化钛,可以改善印花织物的干/湿摩擦牢度。这表明通过双键接枝的颜料参与了可蓝光固化的聚合反应。在蓝光固化油墨中使用改性的二氧化钛,可以改善印花织物的干/湿摩擦牢度。
