Anti-oxidation fireproof coating for surface of silicon carbide product
The invention relates to a preparation method of an anti-oxidation fireproof coating for the surface of a silicon carbide product, which can be used for relieving the oxidation problem of the silicon carbide product. The coating comprises the following components in parts by weight: 75-85 parts of partially-stabilized zirconia fine powder, 10-15 parts of partially-stabilized zirconia particles and 5-10 parts of magnesium aluminate spinel fine powder; in addition, 50-60 parts of a binding agent, 0.1-0.4 part of an additive and 0.05-0.2 part of a thickening leveling agent are also added into the fireproof coating. The materials are ball-milled and uniformly mixed to obtain refractory slurry, and the refractory slurry is uniformly coated on the SiC product, naturally aired, dried at 110 DEG C and subjected to high-temperature treatment to obtain the refractory coating for the surface of the SiC product, which is high in bonding strength and stable in performance. Compared with the coating in the prior art, the prepared coating has the characteristics of high bonding strength, high temperature resistance, good thermal shock resistance and the like.
本发明专利涉及一种碳化硅制品表面用防氧化耐火涂料的制备方法，可用于缓解碳化硅制品的氧化问题。所述涂层按组成及重量份为：部分稳定氧化锆细粉75~85份、部分稳定氧化锆颗粒10~15份、镁铝尖晶石细粉5‑10份；此外耐火涂料还添加50~60份的结合剂、0.1~0.4份的添加剂、0.05‑0.2份的增稠流平剂。按所述物料组成球磨混合均匀得到耐火浆料，在SiC制品上均匀涂敷，自然晾干，110℃烘干后，经高温处理，得到结合强度高、性能稳定的SiC制品表面用耐火涂层。与现有技术的涂料相比，本发明制得的涂层具有结合强度高、耐高温以及抗热震性能好等特点。
