The invention belongs to the technical field of refractory materials, and particularly relates to a preparation method of a high-strength refractory material. The preparation method comprises the following steps: firstly, putting soybean meal and bagasse into water for high-temperature water boiling; mixing the calcined product, phenolic resin, titanium oxide and other materials; and demolding toobtain the high-strength refractory material. Soybean meal and bagasse are subjected to high-temperature water boiling and alkali liquor heating so that plant fibers in the soybean meal and the bagasse are separated, the components such as protein, sucrose and the like contained in the fiber are dissolved, the contact degree between the fiber and other components is improved, the fiber component is carbonized after the high temperature treatment to form the covalent bond adsorption effect so as to improve the structural strength of the refractory material, and the fiber has a certain degree oftoughness and structural strength after carbonization; aluminum ions are introduced into plant fibers, the pH value is adjusted to generate an aluminum hydroxide component, the structural strength ofthe refractory material is enhanced through heating, a certain degree of coating effect is achieved through the fiber component, the thermal stability of the refractory material is improved, and wideapplication prospects are achieved.
本发明属于耐火材料技术领域，具体涉及一种高强度耐火材料的制备方法。本发明首先将豆粕与甘蔗渣投入水中高温水煮，后将煅烧产物、酚醛树脂、氧化钛以及其它物料混合，脱模即得高强度耐火材料，将豆粕、甘蔗渣经过高温水煮和碱液加热使豆粕和甘蔗渣中的植物纤维分离，溶解其中含有的蛋白质、蔗糖等成分，提高纤维与其它成分之间的接触程度，在高温处理后使纤维成分碳化形成共价键吸附作用，提高耐火材料的结构强度，同时纤维在炭化后具有一定程度的韧性和结构强度；将铝离子引入植物纤维中，利用pH值调节生成氢氧化铝成分，经过加热加强耐火材料的结构强度，利用纤维成分进行一定程度的包覆作用，提高耐火材料的热稳定性，具有广阔的应用前景。
