The invention belongs to the technical field of silicon carbide materials, and discloses a silicon carbide coating for a sagger and a preparation method of the silicon carbide coating, the silicon carbide coating comprises the following raw materials in parts by weight: 30-60 parts of silicon carbide powder, 20-30 parts of polyacrylate, 10-20 parts of metal oxide, 5-10 parts of kaolin, 1-10 partsof graphite, 1-3 parts of a binder and 5-10 parts of a solvent. The method comprises the following steps: mixing silicon carbide powder, metal oxide, kaolin and graphite in a powder mixer, carrying out ball milling, dissolving polyacrylate and a binder in a solvent to obtain a mixed solution, adding the mixed solution into the mixed powder, and mixing to obtain the silicon carbide coating. According to the silicon carbide coating provided by the invention, the silicon carbide powder, the metal oxide powder, the water-based organic silicon resin, the polyacrylate, the kaolin and the graphite with different particle sizes are matched, so that the stability and the high temperature resistance of a coating layer are guaranteed, and the coating is not easily corroded by strong acid, strong alkali, a strong chlorinating agent and the like.
本发明属于碳化硅材料技术领域，公开一种用于匣钵的碳化硅涂料及其制备方法，包括如下重量份的原料：碳化硅粉体30‑60份，聚丙烯酸酯20‑30份，金属氧化物10‑20份，高岭土5‑10份，石墨1‑10份，粘结剂1‑3份，溶剂5‑10份；其方法包括：将碳化硅粉体、金属氧化物、高岭土、石墨置于混粉机中混合、球磨；将聚丙烯酸酯、粘结剂溶解于溶剂中得到混合液；将混合液加入混合粉体中混料得碳化硅涂料。本发明提供的碳化硅涂料通过不同粒径的碳化硅粉末、金属氧化粉、水性有机硅树脂、聚丙烯酸酯、高岭土、石墨的配合保证了涂层的稳定性、耐高温、不容易受到强酸、强碱、强氯化剂等腐蚀的优异性能。
