Heat-resistant steel anti-oxidation protective coating material and preparation method thereof
The invention discloses a heat-resistant steel anti-oxidation protective coating material and a preparation method thereof, the coating material is composed of a powder material and a liquid material in a ratio of 1: (1-2.5), the powder material is prepared from the following raw materials in parts by weight: 0.5 to 5 parts of kaolin, 3 to 10 parts of cement, 5 to 15 parts of calcium carbonate, 30 to 55 parts of silicon dioxide, 10 to 20 parts of aluminum oxide, 3 to 10 parts of silicon carbide, 5 to 15 parts of magnesium oxide, 3 to 10 parts of zirconium dioxide, 3 to 10 parts of titanium oxide, 2 to 6 parts of glass powder, 2 to 6 parts of boric oxide, 0.2 to 1 part of sodium chloride and 5 to 15 parts of carbon powder; the liquid material is prepared from the following raw materials in parts by weight: 100-150 parts of sodium water glass with the baume degree of 21.9-41.2, 5-10 parts of a polyvinyl alcohol solution with the concentration of 10%-30% and 10-20 parts of an aluminum dihydrogen phosphate aqueous solution with the concentration of 50%-70%. The preparation method comprises the step of uniformly mixing the liquid material and the powder material according to the proportion to obtain the target coating material. The cement and the glass powder are introduced into the raw materials of the coating material, so that the cost is reduced, the high temperature resistance of a coating and the oxidation resistance of a steel substrate are greatly improved, and a very good protection effect can be achieved without needing to be too thick during spraying.
本发明公开了一种耐热钢抗氧化保护涂层材料及其制备方法，所述涂层材料由配比为1:1‑2.5的粉料和液料组成，其中，所述粉料由以下重量份的原料组成：观音土0.5‑5份、水泥3‑10份、碳酸钙5‑15份、二氧化硅30‑55份、三氧化二铝10‑20份、碳化硅3‑10份、氧化镁5‑15份、二氧化锆3‑10份、氧化钛3‑10份、玻璃粉2‑6份、氧化硼2‑6份、氯化钠0.2‑1份、碳粉5‑15份；所述液料由以下重量份的原料组成：波美度为21.9‑41.2的钠水玻璃100‑150份、10%‑30%的聚乙烯醇溶液5‑10份、50%‑70%的磷酸二氢铝水溶液10‑20份。其制备方法是将液料与粉料按照配比混合均匀得到目标涂层材料。本发明涂层材料原料中引入了水泥和玻璃粉，在降低成本的同时，极大的提高了涂层的耐高温性和钢基体的抗氧化性，喷涂时不需太厚，即可起到很好的保护效果。
