Carbon nanofiber modified carbon-containing refractory castable and preparation method thereof
The invention discloses a carbon nanofiber modified carbon-containing refractory castable which comprises the following raw material components in parts by weight: 90 parts of a refractory raw material, 170 parts of a catalyst, 20 parts of a cementing material, 3 parts of a carbon material, 11 parts of an admixture and 0.9 part of a coagulant, the invention also discloses a preparation method of the carbon-nanofiber-modified carbon-containing refractory castable, which comprises the following steps: S1, putting the selected refractory raw materials in parts by weight into a catalyst, carrying out pressurized stirring, then taking out the impregnated refractory raw materials, and carrying out drying treatment to obtain the dried refractory raw materials. The prepared carbon-nanofiber-modified carbon-containing refractory castable has excellent high-temperature slag corrosion resistance, surface-modified crystalline flake graphite is adopted as a carbon material, the hydrophilicity and dispersity of graphite are improved, and the obtained carbon-containing refractory castable is excellent in performance and can be used for linings or foundations of various high-temperature industrial kilns; and the method can also be used for manufacturing preforms.
本发明公开了一种碳纳米纤维改性的含碳耐火浇注料，包括以下重量份数的原料成分：90份的耐火原料、170份的催化剂、20份的胶结料、3份的碳素材料、11份的掺合料、0.9份的促凝剂；本发明还公开了一种碳纳米纤维改性的含碳耐火浇注料的制备方法，包括以下步骤：S1，将选取重量份的耐火原料投入到催化剂中并进行加压搅拌，然后将浸渍的耐火原料取出干燥处理，得到干燥耐火原料。本发明所制备的碳纳米纤维改性的含碳耐火浇注料拥有优异的抗高温熔渣侵蚀性能，且采用表面改性的鳞片石墨作炭素材料，提高石墨的亲水性和分散性，所得含碳耐火浇注料性能优良，可用于多种高温工业窑炉内衬或者基础，也可用来制造预制件。
