Magnesian binding agent taking used refractory material as raw material and application of binding agent
The invention discloses a magnesium binding agent using a used refractory material as a raw material and application of the binding agent. The magnesium binding agent is composed of magnesium powder and organic acid, the mass ratio of the magnesium powder to the organic acid is 0.1:1-10:1, the magnesium powder is obtained by using the used magnesium refractory material as the raw material through screening, crushing and fine grinding, the particle size of the powder is required to be smaller than 75 microns, the content of magnesium oxide is required to be larger than 40%, the organic acid is any one or a combination of more than one of citric acid, acrylic acid, oxalic acid and the like, and the magnesium binding agent can be used for preparing cement-free refractory castable. The magnesium binding agent can be used for preparing the refractory castable with excellent high-temperature performance, and the utilization rate and the additional value of the used refractory material can be improved; and organic acid in the magnesium binding agent inhibits expansion caused by hydration of magnesium oxide, and a castable blank with good strength can be prepared. The normal-temperature strength of the refractory castable prepared by adopting the magnesium binding agent disclosed by the invention can reach the strength of the traditional calcium aluminate cement binding castable.
本发明公开了一种以用后耐火材料为原料的镁质结合剂及其应用，镁质结合剂是由镁质粉体和有机酸组成，镁质粉体与有机酸的质量比为0.1:1‑10:1，镁质粉体是以用后的镁质耐火材料为原料经筛选、破碎和细磨得到的，要求粉体的粒径小于75μm和氧化镁的含量大于40％，有机酸为柠檬酸、丙烯酸、草酸等中的任一种或一种以上的组合，该镁质结合剂可用于制备无水泥耐火浇注料。本发明的镁质结合剂不仅可制备出高温性能优异的耐火浇注料，且可提高用后耐火材料的利用率和附加值；镁质结合剂中有机酸抑制氧化镁水化带来的膨胀，可制备具有良好强度的浇注料柸体；采用本发明的镁质结合剂制备的耐火浇注料的常温强度可到达传统铝酸钙水泥结合浇注料的强度。
