Preparation method of fireproof material

Abstract

The invention provides a preparation method of a fireproof material. The method comprises the following preparation steps: a, mixing a carbon-containing material, a fireproof base material and aluminum oxide; guiding the mixture into a ball milling tank; performing ball milling; then, adding an organic solvent; stirring to obtain slurry; b, mixing partial stable zirconium oxide, zirconium carbideparticles, acrylated amine, methylene bisacrylamide and ammonium persulfate; guiding the materials into a high mixing machine; performing stirring and ultrasonic oscillation to obtain a first material; c, adding a catalyst and a bonding agent into the first material; performing stirring and dissolution; then, guiding the slurry; heating and stirring to obtain a blank; d, drying and crushing the blank; then, performing secondary drying treatment; next, performing cooling and pressing shaping. Compared with a conventional fireproof material, the prepared fireproof material has the advantages that the air porosity is lower; the bulk density is higher; the expansion rate and the linear change on reheating are smaller; the stability is better; the heat shock performance is more excellent; the wear-resistant performance is better.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a preparation method of refractory materials. Background technique [0002] In the traditional sense, refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 °C. And parts of the material, and can withstand the corresponding physical and chemical changes and mechanical action. [0003] Most refractory materials are made of natural ores (such as refractory clay, silica, magnesite, dolomite), and some industrial raw materials and synthetic raw materials (such as industrial alumina, silicon carbide, synthetic mullite, Synthetic spinel, etc.) are also increasing, so there are many types of refractory materials. According to the mineral composition, refractories can be divided into silica, aluminum silicate, magnesia, dolomite, olivine, spinel, carbonaceous, zirconium-containing refractories and special refr...

Problems solved by technology

[0004] The poor mechanical toughness of inorganic non-metallic materials is a common problem in inorganic non-metallic materials and materials. As refractory materials that belong to inorganic non-metallic materials, their mechanical toughness is also poor. However, its poor mechanical toughness also affects its thermal shock resistance at high temperatures. Due to the large temperature difference between rapid cooling and rapid heating and use, refractory materials are prone to cracking and peeling under the action of thermal expansion and contraction. The situation that affects the integrity of refractory materials reduces the service life of refractory materials; at the same time, for those refractory products that need to be moved frequently, their poor mechanical toughness will greatly increase the damage rate of refractory products and affect their daily use.
