Heating furnace heat storage box repairing material and preparation method thereof
The invention discloses a repairing material for a heat storage box of a heating furnace and a preparation method of the repairing material. The repairing material comprises aggregate, auxiliary materials and a binding agent, the aggregate is prepared from the following components in percentage by weight: 70%-80% of regenerated heat accumulator powder, 5%-8% of silicon oxide micro powder, 5%-10% of power plant porcelain bottle micro powder, 5%-10% of alumina micro powder and 0.5%-2% of metal aluminum powder; the auxiliary material is zirconium-containing refractory fibers, and the addition amount of the auxiliary material in the repairing material is 0.1%-1%; the binding agent is added in the repairing material according to the following amounts: 0.5%-1.5% of resole, 2.5%-3% of aluminate coagulant, 1%-2% of silica gel expanding agent and 1%-2% of industrial tar. The repairing material can be made of waste materials, so that the utilization rate of the waste materials can be effectively increased; the wear-resistant and erosion-resistant thermal shock-resistant coating has good high-temperature adhesion, good wear-resistant and erosion-resistant performance and good durability, has the characteristics of wear resistance, scouring resistance, no falling and good thermal shock stability, prolongs the service life of the thermal shock-resistant coating, and reduces the maintenance cost.
本发明公开了一种加热炉蓄热箱体修补料及其制备方法，其包括骨料、辅料和结合剂；所述骨料由下述重量百分含量的组分组成：再生蓄热体粉末70％～80％、氧化硅微粉5％～8％、电厂瓷瓶微粉5％～10％、矾土微粉5％～10％、金属铝粉0.5％～2％；所述辅料为含锆耐火纤维丝，在修补料中的添加量为0.1％～1％；所述结合剂在修补料中的添加量为：甲阶酚醛树脂0.5％～1.5％、铝酸盐促凝剂2.5％～3％、硅胶膨胀剂1％～2％、工业用焦油1％～2％。本修补料可以采用废旧材料，能有效地提升废料利用率；具有良好的高温粘接性、良好的耐磨耐侵蚀性能以及良好的耐用性，具有耐磨损、耐冲刷、不脱落和热震稳定性好的特点，同时提高了热震稳定使用寿命，降低了维修成本。
