High-strength sintering hollow clay brick and preparation method thereof

Abstract

The invention discloses a high-strength sintering hollow clay brick and belongs to the technical field of hollow bricks. The high-strength sintering hollow clay brick is prepared from the following raw materials in parts by weight: 80-85 parts of clay, 25-28 parts of steel fiber, 17-20 parts of alumina silicate fiber, 12-14 parts of sepiolite powder, 10-14 parts of calcium carbonate, 6-8 parts of zinc oxide, 7-9 parts of polyethylene wax, 13-15 parts of petroleum asphalt, 2-4 parts of lignosulfonate, 6-9 parts of waterproof powder, 3-5 parts of triethanolamine, 1-3 parts of alkylphenol ethoxylates, 8-10 parts of brominated polystyrene, 1-2 parts of anti-freezing agent, 1-2 parts of ultraviolet light absorber, 2-4 parts of antibacterial agent, 5-7 parts of adhesive and a defined amount of water. The invention also discloses a preparation method for the high-strength sintering hollow clay brick. The high-strength sintering hollow clay brick is simply prepared, has excellent strength and fire resistance and is long in service life.

Description

technical field [0001] The invention relates to the technical field of hollow bricks, in particular to a high-strength fired clay hollow brick and a preparation method thereof. Background technique [0002] Clay hollow bricks are made of clay and shale as the main raw materials, which are processed, shaped and sintered. The percentage of the total area of ​​holes in the hollow brick to the area of ​​the brick where it is located is called the porosity of the hollow brick, which should generally be above 15%. Compared with solid bricks, hollow bricks can save a lot of land, soil and fuel for burning bricks, reduce transportation weight; reduce labor intensity during brick making and masonry, speed up construction progress; reduce building weight, increase building layers, and reduce construction costs . [0003] Hollow bricks are used because they are lighter and will not cause cracks in the wall panels. In fact, there are many other partition wall materials, including lig...

Problems solved by technology

The invention mixes domestic waste incineration ash, Yellow River silt, phosphogypsum, calcium carbide mud and other raw materials to make the sintered clay hollow brick, which has the advantages of high strength, crack resistance, impact resistance, corrosion resistance, aging resistance, etc., and has a long service life. It has a wide range of applications and broad market prospects, but the fire performance of this invention is average, and its strength can still be further improved
