Environment-friendly refractory magnesite brick for cement kiln and preparation method of environment-friendly refractory magnesite brick
The invention provides an environment-friendly refractory magnesite brick for a cement kiln and a preparation method of the environment-friendly refractory magnesite brick. The environment-friendly refractory magnesite brick comprises the following raw materials in parts by mass: 60-65 parts of periclase, 1-5 parts of a binder and 32-37 parts of fused magnesite. The binder comprises the following raw materials in parts by weight: 40-60 parts of phosphoric acid, 30-40 parts of water, 8-12 parts of metal hydroxide powder and 0-2 parts of oxalic acid. Compared with the prior art, the binder is prepared from the phosphoric acid, the metal oxide and the oxalic acid as main raw materials, phenolic resin, paper pulp waste liquid, organic powder and other binders are not used, no gas is generated in the heating process of refractory brick preparation, no harmful gas is generated to the environment, and environmental pollution in the refractory brick preparation process is reduced; the waste gas emission of cement enterprises is reduced. Moreover, the compressive strength of a green brick prepared from the binder is higher than that of a conventional green brick, so that the binder is good in cohesiveness.
本发明提供了一种水泥窑用环境友好型耐火镁砖及其制备方法，包括以下质量份原料：方镁石60‑65份，粘结剂1‑5份，电熔镁砂32‑37份；所述粘结剂原料：磷酸：40‑60份，水：30‑40份，金属氢氧化物粉末：8‑12份，草酸：0‑2份。与现有技术相比，本发明以磷酸、金属氧化物和草酸为主要原料制备粘结剂，避免使用酚醛树脂、纸浆废液、有机粉体等粘结剂，在耐火砖制备加热过程中无气体生成，对环境不产生有害气体，本发明减少耐火砖制备过程中的环境污染，降低水泥企业废气排放。且，本发明粘结剂制备的砖坯抗压强度比常规的砖坯大，表明本发明粘结剂粘结性好。
