Embodiment 1

[0018] It is made according to the following ratio of raw materials by weight: 45 parts of calcium aluminate, 30 parts of fly ash, 10 parts of lime, 6 parts of desulfurized gypsum, 2.5 parts of industrial caustic soda, 0.5 parts of quartz sand, 1 part of sodium carbonate, and 1 part of amide 5 parts, 7 parts of water reducer, 5 parts of expansion agent, 45 parts of water. The preparation method is to add calcium aluminate, fly ash and lime to the ball mill according to the ratio of the above raw materials by weight to obtain a composite powder, then add the composite powder to the mixer, spray and add 3 / 5 of the total amount of water, and stir After uniformity, add desulfurization gypsum, industrial caustic soda, quartz sand, sodium carbonate, amide, water reducing agent, expansion agent, and spray the remaining 2 / 5 of the water at a constant speed while stirring. After 0.5 hours, after autoclaving and curing, a refractory lightweight wall material is obtained.

Abstract

The invention discloses a fireproof lightweight wall material and a preparation method thereof. The fireproof lightweight wall material is prepared from the following raw materials by weight: 45-65 parts of calcium aluminate, 30-45 parts of fly ash, 10-25 parts of lime, 6-10 parts of flue gas desulfurization gypsum, 2.5-5 parts of industrial caustic soda, 0.5-3 parts of quartz sand, 1-5 parts of sodium carbonate, 1-6 parts of amide, 7-15 parts of a water reducing agent, 5-10 parts of an expansive agent and 45-65 parts of water. The preparation method is as below: adding calcium aluminate, fly ash and lime according to weight portion to a ball mill for grinding, so as to obtain a composite powder, and then adding the composite powder into a mixer, spraying and adding water 3 / 5 of the total amount, evenly stirring, successively adding desulfurization gypsum, industrial caustic soda, quartz sand, sodium carbonate, amide, water reducing agent and expansive agent, stirring while uniformly spraying the remaining 2 / 5 of the water, evenly mixing, casting for molding, standing for 0.5-2.5 h, and conducting autoclaved curing, so as to obtain the fireproof lightweight wall material.

Description

technical field [0001] The invention relates to wall materials, in particular to a refractory lightweight wall material and a preparation method thereof. Background technique [0002] The "911" bombing in the United States suffered heavy losses. The American media analyzed that the main reason for the collapse of the building was that the protective layer of the steel structure failed to play a better role in heat insulation and protection, and lost its supporting capacity at high temperatures. At present, although the U.S. survey report has not yet been published, it gives us enlightenment from the negative side: my country's Shanghai, Guangzhou, Shenzhen and some large cities have successively emerged high-rise and super high-rise buildings, and Lanzhou is also full of high-rise buildings, most of which are frame structures. The body filling materials are fly ash aerated blocks, clay hollow bricks, etc. There are many problems in fire prevention and fire protection, and it...
