Problems solved by technology

[0002] Refractory materials refer to a class of coatings that are coated on the surface of objects to prevent fires, prevent the spread of fire or isolate fire sources, prolong the ignition time of substrates or increase thermal insulation performance to delay structural damage. Currently, aluminum used in continuous casting Carbonaceous refractories are directly coated on the surface of steel, but the existing aluminum-carbon refractories generally have the disadvantages of weak corrosion resistance, corrosion resistance and poor durability. Therefore, we propose a method that can improve corrosion resistance High-alumina carbonaceous refractory material and preparation method thereof

Abstract

The invention discloses a high-aluminum carbonaceous refractory material capable of improving erosion resistance. The material comprises the following components: in terms of mass percentage, 15-22% of polystyrene resin, 8-12% of organosilicon resin, 5.5-7.5% of C9 petroleum resin, 4.8-6.4% of metal silicon powder and the balance water. The invention also discloses a preparation method of the high-aluminum carbonaceous refractory material capable of improving the erosion resistance, and the preparation method includes the following step: performing compounding and mixing, preparing modified amaleic acid solution, performing secondary mixing, and conducting filtration. The formula is more reasonable, after different treatment are performed on the polystyrene resin, organosilicon resin andC9 petroleum resin, the compactness of the molecular structure of the product can be increased through combined addition of multiple high-aluminum carbonaceous materials including the metal silicon powder, silicon carbide and aluminum oxide, so that the erosion resistance and corrosion resistance of the product are improved; and the adopted materials are non-toxic, and the high-aluminum carbonaceous refractory material has the advantages of environmental protection and no pollution.
