Refractory coating for surface of silicon carbide product
The invention relates to a refractory coating for the surface of a silicon carbide push plate. The refractory coating can be used for oxidation resistance of silicon carbide and prevention of adhesionof related products. The coating comprises, by weight, 10-30 parts of aluminum oxide micro powder, 50-80 parts of zirconium oxide fine powder and 10-30 parts of tabular corundum particles, and further comprises 30-60 parts of a binding agent, 0.1-0.4 parts of an additive and 0.05-0.2 parts of a thickening leveling agent. The preparation method comprises the following steps: uniformly mixing the components to obtain refractory slurry, uniformly coating a SiC product with the refractory slurry, naturally airing, and carrying out high-temperature treatment to obtain the refractory coating with high bonding strength and stable performance for the surface of a SiC product. Compared with the coating in the prior art, the prepared coating has the characteristics of high bonding strength, high temperature resistance (the highest use temperature can reach 1600 DEG C), favorable thermal shock resistance, long service life and environment friendliness, and is simple to operate.
本发明专利涉及一种碳化硅推板表面用耐火涂料，可用于碳化硅抗氧化以及防止相关制品粘连的问题。所述涂层按组成及重量份为：氧化铝微粉10~30份，氧化锆细粉50~80份，板状刚玉颗粒10~30份；此外所用结合剂30~60份，所用质量为0.1~0.4份的添加剂和0.05‑0.2份增稠流平剂。按所述组成混合均匀得到耐火浆料，在SiC制品上均匀涂敷，自然晾干，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（最高使用温度可达1600℃）以及抗热震性能好、操作简单、使用寿命长、绿色环保的特点。
