Alumina-based porcelain insulator porcelain body and preparation method thereof
The invention discloses a preparation method of an alumina-based porcelain insulator porcelain body. The preparation method comprises the following steps: (1) preparing composite powder; (2) obtaining coated powder; (3) obtaining phosphorus modified powder; (4) performing wet ball milling and mixing on aluminum oxide, the phosphorus modified powder, diboron trioxide, potassium feldspar powder, talcum powder, wollastonite powder, kaolin and zirconium silicide in a ball mill to obtain mixed pug; pressing mud, performing compression molding to prepare a blank, and sintering to obtain the porcelain insulator porcelain body. The insulator porcelain body prepared by the method disclosed by the invention has good low-temperature cycle resistance and mechanical property, so that the insulator can be applied to an environment with relatively low air temperature and severe weather change, and the service time of the insulator in the environment is prolonged.
本发明公开了一种氧化铝基瓷绝缘子瓷体的制备方法，包括如下步骤：(1)制备复合粉体；(2)获得包覆粉体；(3)获得磷改性粉末；(4)将氧化铝、所述磷改性粉末、三氧化二硼、钾长石粉、滑石粉、硅灰石粉、高岭土和硅化锆在球磨机中湿法球磨混料获得混合泥料；榨泥，压制成型制成坯料，烧结，获得所述瓷绝缘子瓷体。本发明所述方法制备的绝缘子瓷体具有良好的耐低温循环性能和机械性能，使得绝缘子能够应用于气温较低，天气变化恶劣的环境，提高了绝缘子在这种环境下的服役时长。
