The invention relates to a refractory material for pressing in and repairing and a preparation method thereof. The present invention solves the foaming phenomenon existing in the technical field at present, and causes more pores to exist in the gunning area, which leads to the lack of dense lining and easy damage and spalling at high temperature. Technical measures to solve: Refractories for pressing repair, which is its contained components and weight: organic binder and refractory material: 3~35 matrix: 20~80 copies, 1~10 copies: additive. Preparation method: in accordance with the number of copies of two and more than two kinds of materials in bauxite, coke, gem corundum, clay, silicon carbide, carbon, mixed preparation become refractory matrix, and adding additives; in accordance with the number of copies added tar and silicone resin, thermoplastic phenolic resin and stirring the mixture in 60 ~ 200 degrees under the conditions of heating to prepare organic binder; refractory matrix mixture will be made of organic binder and additives have been added by mixing and stirring evenly after packing for.

技术介绍
目前，在采用压入方法修补高炉、RH真空炉、混铁炉等设备时，其使用的耐火材料主要为两类，即水性结合材料和以酚醛树脂为结合剂的材料。水性结合材料主要由水玻璃、水泥、磷酸盐结合而成，其主要化学成分为Al2O3、、Fe2O3、K2O+Na2O、SiC，结合剂为磷酸二氢铝，如专利号为01133640.4的已公开的用于转炉的修补耐火材料专利，主要组成为烧结镁砂、白云石、偏硅酸钠、六偏磷酸钠；专利号为01106497.8的专利，也公开了用于钢包的修补耐火材料，主要组成为电熔镁砂、镁铬粉、三聚磷酸钠、六偏磷酸钠、硅灰、复合添加剂，这些均为水性材料结合，粘接强度较高；但在高温下，由于在喷补时有发泡现象，使得喷补处有较多气孔存在，导致其修补的炉衬不致密，在高温下易受损剥落。以酚醛树脂为结合剂的材料，主要由矾土、焦宝石、粘土、碳化硅、碳、金属硅等组成。如日本住友公司以酚醛树脂结合的修补料，其主要的化学成分为Al2O3、SiO2、、SiC或MgO、SiC、固定碳；国内，冶金建筑总院报道了以热塑性酚醛树脂结合的修补料，其主要的化学成分为Al...
【技术保护点】
用于压入修补的耐火材料，其特征在于其所含组分及重量份为：有机结合剂：３～３５份、耐火材料基体：２０～８０份、添加剂：１～１０份。
