Light-cured diatomite ceramic paste material and preparation method thereof
The invention discloses light-cured diatomite ceramic paste material and a preparation method thereof. The paste material comprises ceramic powder, a surface modifier, premixed liquid and a dispersingagent, the ceramic powder is diatomite powder subjected to soda ash heat treatment; the premixed solution comprises a mixture A and a photoinitiator; the preparation method comprises the following steps: firstly, taking diatomite powder subjected to soda ash heat treatment as a ceramic powder raw material, adding a surfactant and a dispersing agent into the ceramic powder raw material, taking absolute ethyl alcohol as a wet grinding medium, and carrying out ball-milling modification in a ball mill to obtain ceramic mixed powder; then mixing cycloaliphatic epoxy resin CY179, 1, 6-hexanediol diacrylate and dipentaerythritol hexaacrylate according to a mass ratio to form a mixture A; adding the photoinitiator into the mixture A to obtain a premixed solution; and finally, adding the ceramic mixed powder into the premixed solution, and uniformly stirring in a homogenizer to obtain the diatomite ceramic paste material. The photocuring molding of the diatomite ceramic complex part can be realized.
一种光固化硅藻土陶瓷膏料及其制备方法，膏料包括陶瓷粉体、表面改性剂、预混液和分散剂；陶瓷粉体为经纯碱热处理过的硅藻土粉末；预混液包括混合物A和光引发剂；制备方法是先将经纯碱热处理过的硅藻土粉末作为陶瓷粉体原材料，在其中加入表面活性剂和分散剂，以无水乙醇作为湿磨介质，在球磨机中球磨改性得到陶瓷混和粉末；然后按照质量比混合脂环族环氧树脂CY179、1,6一己二醇二丙烯酸酯、双季戊四醇六丙烯酸酯形成混合物A；在混合物A中加入光引发剂得到预混液；最后将陶瓷混和粉末加入至预混液中，在均质机中搅拌均匀，得到硅藻土陶瓷膏料；本发明能够实现硅藻土陶瓷复杂件的光固化成型。
