Preparation method of thermal shock resistant composite nozzle brick
The invention discloses a preparation method of a thermal shock resistant composite nozzle brick, and relates to the technical field of refractory materials. According to the method, isoliquiritigenin modified phenolic resin is used as a binder, (-)-epigallocatechin modified rosin resin is used as an antioxidant, bauxite clinker, semi-soft clay, zirconium dioxide and clay clinker are added for mixing, and the thermal shock resistant composite nozzle brick is prepared through pressure forming, drying, sintering, vacuum oil immersion, carbonization and polishing. The refractory material has the characteristics of low porosity, high volume density, good thermal shock resistance stability and good oxidation resistance.
本发明公开了一种抗热震性复合水口砖的制备方法，涉及耐火材料技术领域。该方法采用异甘草素改性的酚醛树脂作为粘结剂，以(‑)‑表没食子儿茶素改性的松香树脂作为抗氧化剂，加入铝矾土熟料、半软质粘土、二氧化锆、粘土熟料混炼，经过加压成型，干燥，烧成，真空油浸，碳化，磨光，制得的抗热震性复合水口砖，具有气孔率低、体积密度高，抗热震稳定性好，抗氧化性好的特性。
