Coating for prolonging service life of gasifier refractory brick and preparation method thereof
The invention belongs to the technical field of coatings in gasification furnaces, and particularly relates to a coating for prolonging the service life of a refractory brick of a gasification furnace and a preparation method thereof, and the coating comprises the following raw material components: a matrix raw material, an organic binder, an inorganic binder and water; based on 100 wt% of the total weight of the slurry, the content of the matrix raw material is 1.0-20.0 wt%, the content of the organic binder is 1.0-20.0 wt%, and the content of the inorganic binder is 1.0-40.0 wt%; and the balance of water. Uniformly brushing the slurry on a fire-facing surface of a high-chromium refractory brick of the gasification furnace, and drying in air at room temperature to prepare a fire-facing surface coating; the thickness of the coating is larger than or equal to 0.5 mm and smaller than or equal to 2mm. The fire-facing surface coating of the gasification furnace refractory brick can effectively reduce the loss of chromium content on the surface of the refractory brick, so that the service life of the refractory brick is prolonged.
本发明属于气化炉中涂层的技术领域，尤其涉及一种延长气化炉耐火砖寿命的涂层及其制备方法，涂层的原料组分包括：基体原料、有机粘结剂、无机粘结剂、水；以浆液总重量为100wt％计，基体原料的含量为1.0‑20.0wt％，有机粘结剂的含量为1.0‑20.0wt％，无机粘结剂的含量为1.0‑40.0wt％；余量为水。将浆液均匀刷涂在气化炉高铬砖耐火砖的向火面上，再在室温下空气干燥，制得向火面涂层；涂层的厚度大于等于0.5mm且小于等于2mm。本发明的气化炉耐火砖的向火面涂层，可有效降低耐火砖表面的铬含量的损失，从而延长耐火砖寿命。
