Carbon nanofiber modified carbon-containing refractory castable and preparation method thereof
The invention discloses a carbon nanofiber modified carbon-containing refractory castable and a preparation method thereof. The carbon nanofiber modified carbon-containing refractory castable comprises the following components in parts by weight: 100 parts of aggregate, 10-30 parts of cementing material, 8-15 parts of admixture and 0.2-0.8 part of coagulant, wherein the aggregate is obtained by mixing and sintering a refractory material and a refractory material coating liquid; and the refractory material coating liquid is a phenolic resin solution modified by ceric ammonium nitrate. A series of improvements are made on the refractory castable based on the defects that the refractory castable and the slag in the market have strong wettability and poorer slag corrosion resistance. A metal oxide conventionally used in aggregate components of the refractory castable is coated with the modified phenolic resin solution and then sintered, and finally the carbon-nanofiber-modified carbon-containing refractory castable is obtained.
本发明公开了一种碳纳米纤维改性的含碳耐火浇注料及其制备方法，碳纳米纤维改性的含碳耐火浇注料按照重量份数计算，包括：100份骨料、10～30份胶结料、8～15份掺和料和0.2～0.8份促凝剂；其中，骨料是使用耐火材料和耐火材料包覆液混合后经过烧结得到；耐火材料包覆液为硝酸铈铵改性后的酚醛树脂溶液。本发明基于市场上的耐火浇注料与炉渣具有强润湿性，抗渣侵蚀性能较差的缺陷对耐火浇注材料进行了一系列的改进。将耐火浇注材料的骨料成分中常规使用的金属氧化物使用改性后的酚醛树脂溶液进行包覆处理，然被进行烧结，最终得到碳纳米纤维改性的含碳耐火浇注料。
