Anti-deformation multi-layer heat-insulating composite brick for rotary kiln and preparation method of anti-deformation multi-layer heat-insulating composite brick
The invention discloses an anti-deformation multilayer heat insulation composite brick for a rotary kiln, the anti-deformation multilayer heat insulation composite brick is composed of coarse aggregate, fine aggregate, auxiliary materials and a modified rheological agent, the coarse aggregate is composed of fused magnesia-alumina spinel, fused magnesia and sintered magnesia; the fine aggregate is composed of active magnesium aluminate spinel micro powder and lanthanum oxide micro powder; the auxiliary material is composed of chlorinated paraffin, foaming microbeads and a binding agent; the modified rheological agent is synthesized from a modified monomer, ammonium persulfate, methacrylic acid, methoxy polyethylene glycol and glyceryl monostearate; the preparation method of the composite brick comprises the following steps: S1, preparing working raw materials; s2, preparing a heat insulation raw material; s3, pressing to form a blank; s4, firing and forming; according to the composite brick, magnesium aluminate spinel and the like are used for heat insulation, and the rheological property of the composite brick is improved by adding the modified rheological agent, so that the anti-deformation degree of the composite brick is improved.
本发明公开了一种抗形变的回转窑用多层隔热复合砖，由粗骨料、细骨料、辅料、改性流变剂组成，其中，所述粗骨料由电熔镁铝尖晶石、电熔镁砂、烧结镁砂组成；所述细骨料由活性镁铝尖晶石微粉与氧化镧微粉组成；所述辅料由氯化石蜡、发泡微珠、结合剂组成；所述改性流变剂是由改性单体与过硫酸铵、甲基丙烯酸、甲氧基聚乙二醇、单硬脂酸甘油酯合成得到；上述复合砖的制备方法包括以下步骤：S1、工作原料准备；S2、隔热原料准备；S3、压制成坯；S4、烧制成型；本发明复合砖除了利用镁铝尖晶石等进行隔热外，还通过加入改性流变剂提高复合砖的流变性能，从而提高其抗形变的程度。
