Non-stick aluminum castable and preparation method thereof

The invention provides a non-stick aluminum castable and a preparation method thereof. The non-stick aluminum castable is prepared from the following raw material components: 65-67 wt% of high-alumina aggregate; 10 wt% to 12 wt% of high aluminum fine powder; 4 wt%-6 wt% of calcined alpha alumina micro powder; 3 wt%-5 wt% of an expanding agent; 3 wt%-4 wt% of wollastonite powder; 4 wt%-5 wt% of a flowable agent; 5 wt% to 7 wt% of aluminate cement; the mass of the high-efficiency water reducing agent is 0.2-0.3% of the total mass of the components. Compared with the prior art, the non-stick aluminum castable provided by the invention has the advantages that specific components with specific contents are adopted, relatively good integral interaction is realized, and the obtained non-stick aluminum castable has excellent molten aluminum erosion resistance and permeation resistance, and is high-temperature-resistant, high in strength and good in thermal shock resistance. 本发明提供了一种不沾铝浇注料及其制备方法；所述不沾铝浇注料由以下组分的原料制备而成：高
