Binder for aluminum-magnesium ramming refractory material and preparation method thereof
The invention discloses a binder for an aluminum-magnesium ramming refractory material and a preparation method of the binder. The refractory material specifically comprises the following raw materials in parts by weight: 15-30 parts of corundum, 15-30 parts of aluminum oxide, 15-30 parts of magnesium oxide, 4-6 parts of a water reducing agent, 5-10 parts of a plasticizer, 15-30 parts of a gelling agent, 10-15 parts of a dispergator, 4-6 parts of a coagulant, 4-6 parts of a retarder, 5-10 parts of a delayed coagulant, 5-10 parts of a foaming agent, 3-6 parts of a defoaming agent, 4-6 parts of a shrink-proof agent, 5-8 parts of a preservative, 2-4 parts of an inhibitor and the balance of water. By arranging the water reducer, the mixing water consumption can be remarkably reduced under the condition that the flow value of the refractory castable is basically unchanged, the plasticity of a refractory material mixture can be improved by the plasticizer, the strain capacity of pug under the stress effect is improved, a colloidal solution can be coagulated by the gelling agent, and the viscosity of the pug is improved. The gelling agent is mainly an inorganic electrolyte and an inorganic acid, and the dispergator can convert agglomerated or agglomerated colloidal particles into sol or uniformly dispersed suspended particles.
本发明公开了一种铝镁质捣打耐火材料用粘结剂及其制备方法，其具体包括如下重量份数原料：刚玉15‑30份、三氧化二铝15‑30份、氧化镁15‑30份、减水剂4‑6份、增塑剂5‑10份、胶凝剂15‑30份、解胶剂10‑15份、促凝剂4‑6份、缓凝剂4‑6份、迟效促凝剂5‑10份、发泡剂5‑10份、消泡剂3‑6份、防缩剂4‑6份、保存剂5‑8份和抑制剂2‑4份，其余为水。本发明通过设置减水剂能在保证耐火浇注料流动值基本不变的情况下，显著降低其拌合用水量，增塑剂能增大耐火材料混合料的可塑性，提高泥料在应力作用下的应变能力，胶凝剂能使胶体溶液发生凝聚，胶凝剂主要是无机电解质和无机酸，解胶剂能使凝聚或团聚的胶粒转化为溶胶或均匀分散的悬浮颗粒。
