Nanometer titanium dioxide ceramic paste material for photocuring and preparation method thereof
The invention discloses a nanometer titanium dioxide ceramic paste material for photocuring and a preparation method thereof. The nanometer titanium dioxide ceramic paste material comprises TiO2 powder, gamma-glycidyl ether oxypropyl trimethoxy silane, sodium hexametaphosphate, a Tego 685 wetting dispersant, a monomer, a compatilizer and a photoinitiator. According to the invention, the monomer with a specified content is added to serve as a dilution paste material, so viscosity effect is reduced, the paste material is prevented from being too thin, the hardness of a photocuring product is improved, and the shrinkage rate of the product is reduced; and high-functional-group resin in the monomer can increase curing depth and improve curing efficiency, and the photoinitiator is cooperativelyused with the monomer, so the action effect of the surface of paste and ultraviolet light is relatively violent, a surface layer of the paste can be initiated to undergo quick curing and to penetrateinto the paste, the stability of the reaction of the surface of the paste and the ultraviolet light is improved, the curing efficiency is further improved, and photocuring molding is facilitated.
本发明公开了一种光固化用纳米二氧化钛陶瓷膏料及其制备方法，包括TiO粉末、Y‑缩水甘油醚氧丙基三甲氧基硅烷、六偏磷酸钠、迪高685湿润分散剂、单体、相容剂和光引发剂，加入指定含量的单体作为稀释膏料，降低粘度作用且防止膏料过稀，同时增加光固化产品的硬度，降低产品收缩率；单体中的高官能团树脂能够提高固化深度，提高固化的效率，结合光引发剂使膏料表面与紫外光作用效果比较剧烈，可引发膏料表面层迅速固化，深入膏料内部，提高膏料表面与紫外光反应的稳定行，进一步提高固化效率，有利于光固化成型。
