Anti-flashover coating on aluminum oxide ceramic surface and preparation method of anti-flashover coating
The invention discloses an anti-flashover coating on an aluminum oxide ceramic surface and a preparation method, the anti-flashover coating is prepared by a slurry coating method, the slurry is composed of mixed powder and an organic carrier, the mixed powder comprises 70%-90% of chromium sesquioxide, 5%-15% of feldspar powder, 0-5% of zirconium dioxide and 5%-15% of silicon dioxide; the organic carrier comprises 96%-99% of water, 0.2%-2.0% of methyl cellulose and 0%-2% of polyethylene glycol; the mixed powder and the organic carrier are uniformly stirred according to a certain weight ratio. The coating can be prepared by dip-coating or brush-coating and can be finished by one-time coating and sintering, the process is simple, the cost is low, the coating is sintered compactly, and the coating performance repeatability is good; meanwhile, water is used as a solvent, and is non-toxic, pollution-free and environment-friendly.
本发明公开一种氧化铝陶瓷表面的防闪络涂层及制备方法，防闪络涂层采用浆料涂覆法制备，所述浆料由混合粉料和有机载体两部分组成，混合粉料包含：三氧化二铬70％～90％、长石粉5％～15％、二氧化锆0～5％、二氧化硅5％～15％；有机载体中包含水96％～99％、甲基纤维素0.2％～2.0％、聚乙二醇0％～2％；所述混合粉料与所述有机载体按一定重量占比搅拌均匀。本发明涂层可采用浸涂或刷涂制备，一次涂覆烧结即可完成，工艺简单成本低，涂层烧结致密，涂层性能重复性好；同时用水为溶剂，无毒无污染，对环境友好。
