preparation example Construction

[0043] The invention also provides a method for preparing a refractory material, which is prepared by mixing the main refractory material and auxiliary materials;

[0044] The auxiliary material includes a lignin-sugar composition;

[0045] The lignin-sugar composition comprises lignosulfonate and sugars;

[0046] The sugar is selected from one or more of monosaccharides, disaccharides, oligosaccharides and sugar alcohols;

[0047] The mass ratio of the lignosulfonate to sugar is (10-90):(90:10).

[0048] The present invention does not limit the mixing method of the main material and auxiliary material of the refractory material, and the mixing method known to those skilled in the art is sufficient. The mixing temperature is preferably 0-100°C, more preferably 10-80°C, and most preferably 20 to 60°C, most preferably 30 to 55°C. The compositions and proportions of the main and auxiliary materials of the refractory material in the present invention have been clearly defined a...

Abstract

The invention provides a refractory material which is prepared from a refractory-material main material and an auxiliary materials. The auxiliary material comprises a lignin-saccharide composition and phenol formaldehyde resin; the lignin-saccharide composition comprises lignosulfonate and saccharides; the saccharides are selected from one or more of monosaccharide, disaccharide, oligosaccharide and sugar alcohol; the mass ratio of the lignosulfonate to the saccharides is (5 to 90):(90 to 5). The refractory material provided by the invention is prepared from the refractory-material main material and the auxiliary materials, wherein the auxiliary material comprises the lignin-saccharide composition. The lignin-saccharide composition provided by the invention can partially replace the phenol formaldehyde resin to be used as an adhesive of the refractory material, has a good adhering effect when being applied to the field of the refractory material. Moreover, the lignin-saccharide composition provided by the invention is low in preparation cost, has no residual harmful substances such as free phenol, free aldehyde and the like, and is environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of materials, including fired and non-fired refractory materials, and is especially used in the field of non-fired refractory materials. Background technique [0002] Refractory materials are inorganic non-metallic materials with a refractoriness of not less than 1580°C. There are many types of refractory materials, which are usually divided into ordinary refractory materials (1580-1770°C), advanced refractory materials (1770-2000°C) and special-grade refractory materials according to their refractoriness. Materials (above 2000°C); according to chemical properties, they are divided into acidic refractory materials, neutral refractory materials and basic refractory materials. The chemical composition of refractory materials is divided into main components and auxiliary components. The auxiliary components include additive components. These additives can be called mineralizers, stabilizers, sintering agents, w...
