Abstract

The invention relates to a novel green fireproof mortar and a preparation method thereof. The fireproof mortar is prepared from the following raw materials in parts by weight: water glass, a coagulating material, a fireproof material and crystal nuclein, wherein the coagulating material is lead and zinc iron tailing slag or coal ash or grain slag of steelworks; the fireproof material is one of fireclay, open-pored expanded perlite, closed-pored expanded perlite, expanded and vitrified small balls and slag. The novel green fireproof mortar adopts an appropriate industrial waste residue as a raw material, and the novel fireproof mortar is produced by adopting a reasonable technology, so that the novel green fireproof mortar has relatively high economical, social and environmental meanings.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a novel green refractory mortar and a preparation method thereof. Background technique [0002] At present, the common refractory mortars in the market have high raw material prices, poor economy and high energy consumption. Using suitable industrial waste residue as raw material and adopting a reasonable process to produce new refractory mortar can realize the resource utilization of solid waste and effectively reduce the engineering cost of refractory mortar. The refractory mortar can be used in building walls to effectively resist fire and protect the environment. Significantly improving the fire safety of buildings has strong economic, social and environmental significance. Contents of the invention [0003] The object of the present invention is to provide a new type of green refractory mortar and its preparation method. By using industrial waste residues as raw ma...
