Anti-skinning, acid and alkali corrosion-resistant and fire-resistant spray coating for smoke chamber of cement kiln and preparation method of spray coating
The invention belongs to the technical field of refractory materials, and particularly relates to an anti-skinning and acid and alkali corrosion resistant refractory spray coating for a smoke chamber of a cement kiln and a preparation method thereof, the anti-skinning and acid and alkali corrosion resistant refractory spray coating comprises the following components in percentage by weight: 50%-70% of aggregate, 20%-42% of micro powder, 3%-5% of a binding agent, 1%-2.7% of an expanding agent, 2%-3% of an antioxidant, 0.1%-0.5% of an anti-explosion agent, 0.1%-0.5% of an anti-skinning agent and 0.15%-0.2% of a dispersing agent; the maximum particle size of the aggregate is less than or equal to 3mm, the dispersing agent comprises calcium citrate and ether polycarboxylate, and the mass ratio of the calcium citrate to the ether polycarboxylate is 1: (6-9). Compared with a traditional fire-resistant spray coating, the anti-skinning, acid-base-resistant and fire-resistant spray coating for the smoke chamber of the cement kiln is high in high-temperature compression strength, good in wear resistance and shock resistance, high in acid-base erosion resistance, good in skinning resistance, excellent in construction performance and capable of better adapting to complex working conditions in the smoke chamber.
本发明属于耐火材料技术领域，具体涉及一种水泥窑烟室用抗结皮耐酸碱腐蚀耐火喷涂料及其制备方法，以重量百分比计，包括50%‑70%的骨料、20%‑42%的微粉料、3%‑5%的结合剂、1%‑2.7%的膨胀剂、2%‑3%的抗氧化剂、0.1%‑0.5%的防爆剂、0.1%‑0.5%的抗结皮剂以及0.15%‑0.2%的分散剂；所用骨料最大颗粒粒径≤3mm，所用分散剂包括柠檬酸钙和醚基聚羧酸酯，其两者的质量比为1：（6‑9）。本发明的水泥窑烟室用抗结皮耐酸碱耐火喷涂料，相较于传统耐火喷涂料，高温耐压强度高，耐磨抗震性能佳，耐酸碱侵蚀能力强，具备良好的抗结皮能力，并且施工性能优异，能够更好的适应烟室中复杂的工况。
