Abstract

The invention discloses a siliceous composite plate, and a preparation method and application thereof. The siliceous composite plate comprises, by weight, 60%-70% of silicon carbide/silicon nitride/silicon oxide, 10%-15% of zirconium oxide, 2%-4% of manganese oxide, 3%-3.5% of titanium oxide, 1%-2% of magnesium oxide, 1.5%-3% of alumina, 1%-3% of yttrium oxide and 2%-10% of adhesive. The siliceous composite plate has the advantages of being resistant to high temperature, small in deformation, high in strength and oxidation-resistant capability and regular in appearance and remarkably prolonging service life, and solves the problems that in the prior art, a fire-resistant thermal insulation material is poor in oxidation resistance, cracks easily, and is poor in thermal insulation performance and high-temperature bending strength and the like. The siliceous composite plate can be applied to waste incineration furnaces, industrial kilns, boilers, smelting furnaces, engines and power station combustion furnaces and has the capability of being resistant to any thermal shock.

Description

technical field [0001] The invention relates to a plate and its preparation method and application, especially a siliceous composite plate and its preparation method and application. It belongs to the field of energy saving and environmental protection. Background technique [0002] Nowadays, the selection requirements for refractory insulation materials in various fields are based on heat insulation, light weight, high temperature resistance and long service life. Refractory insulation materials refer to inorganic non-metallic materials with a refractoriness greater than or equal to 1580 degrees, which can resist sudden temperature changes and slag erosion to a certain extent, and can withstand high temperature loads. Refractory materials are mainly used in high-temperature thermal equipment and various kilns in industrial production. The inner walls of industrial equipment and various kilns must have high temperature resistance, certain strength and good thermal insulati...
