Problems solved by technology

[0004] The disadvantages of the existing refractory materials: metal oxides are used as vegetation refractory materials. Due to the good thermal conductivity of metal oxides, in the case of long-term fire, the temperature of the metal oxides will be very high. High temperature will increase the tensile stress inside the material, causing the material to crack continuously from the inside, affecting subsequent use

Abstract

The invention discloses an environment-friendly aluminum alloy refractory material and a preparation method thereof. The environment-friendly aluminum alloy refractory material comprises, by weight, 20-30 parts of aluminum alloy, 20-40 parts of aluminum oxide, 10-20 parts of silicon nitride, 10-15 parts of boron nitride, 10-15 parts of zirconium oxide, 15-20 parts of sodium silicate, 5-10 parts ofhydrochloric acid, 10-15 parts of ammonia monohydrate and 5-10 parts of an epoxy toughness modifier. The aluminum hydroxide structure with the reticular structure and the aluminum alloy jointly act,the reticular structure is stable, the added aluminum alloy can absorb heat, and the absorbed heat is not intensively transmitted, so that large tensile stress is not generated in the material, the material is effectively prevented from cracking, and the service life of the fireproof material is prolonged.
