Abstract

The invention discloses a slag, carbide slag and ceramsite high-strength wall thermal insulation material and a preparation method thereof. The high-strength wall thermal insulation material is prepared from slag powder, carbide slag powder, ceramsite, sand, calcium carbonate, latex powder, cellulose ether and water; the mass percent is 10.0 to 50.0% of slag powder, 8.0 to 40.0% of carbide slag powder, 30.0 to 60.0% of ceramsite, 15.0 to 30.0 % of sand, 5.0 to 20.0% of calcium carbonate, 1.5 to 5.0% of latex powder, 0.5 to 2.0% of cellulose ether and 12.0 to 30.0% of water. The high-strength wall thermal insulation material disclosed by the invention can improve an internal maintenance function of a cementing system; 28d compressive strength of the wall material can reach 25MPa, and the wall material is small in shrinkage; the slag and the carbide slag serve as the cementing system to replace cement, so that a novel path for resourceful utilization of carbide slag is provided, and high energy consumption required by producing cement is saved; the wall material has excellent thermal insulation performance, high strength, convenience to construction and no independent construction; the materials are wide in source and low in price; compared with a polyphenyl granule macromolecule thermal insulation material, the production cost of the wall material is low.

Description

technical field [0001] The invention relates to a wall thermal insulation material and a preparation method thereof, in particular to a high-strength wall material and a preparation method thereof. Background technique [0002] At present, industries such as electric power, cement, steel, and aluminum produce a large amount of solid waste, and these solid wastes, such as fly ash, slag, steel slag, red mud, etc., are in urgent need of bulk utilization, comprehensive treatment, and reduction of environmental pollution. [0003] There are many kinds of fireproof and thermal insulation materials for walls mainly used at home and abroad. Organic thermal insulation materials frequently cause fires, have poor fire prevention effect and high cost; inorganic fireproof and thermal insulation materials are complicated, and high-quality fireproof and thermal insulation materials often fail to occupy the market due to price wars. Wall insulation materials are mainly made of polymer mater...
