Aluminate cement and unshaped refractory material combined repair material and preparation method thereof
The invention discloses an aluminate cement and unshaped refractory material combined repairing material and a preparation method thereof, aiming at the characteristics of aluminate cement, refractory mortar for repairing is prepared from an aggregate powder mixture of Al2O3-SiO2 series clinker, fine powder, Guangxi clay, alpha alumina micropowder, silica fume and the like, and binding agents of aluminate cement, phosphoric acid solution and the like; a binding agent contained in the refractory mortar can form a new binding phase with aluminate refractory cement in the residual lining body, so that effective combination is formed between the residual lining body and the repairing material, and the phenomena of'two layers' and re-falling when the repairing material is baked to high temperature are avoided; and the service life of the aluminate cement combined unshaped refractory material lining body is prolonged.
本发明公开了一种铝酸盐水泥结合不定形耐火材料修补料及其制备方法，针对铝酸盐水泥特性，由Al2O3‑SiO2系熟料、细粉、广西粘土、α氧化铝微粉、微硅粉等骨料粉料混合物和铝酸盐水泥、磷酸溶液等结合剂制备出修补用耐火胶泥，耐火胶泥内部所含的结合剂能与残存衬体内的铝酸盐耐火水泥形成新的结合相，使残存衬体和修补料之间形成有效结合，从而避免了出现＂两层皮＂和烘烤至高温时再次发生脱落现象，提高了铝酸盐水泥结合不定形耐火材料衬体的使用寿命。
