Antibacterial and abrasion-resistant aerated brick and method for preparing same

Abstract

The invention discloses an antibacterial and abrasion-resistant aerated brick and a method for preparing the same. The method for preparing the antibacterial and abrasion-resistant aerated brick includes mixing and grinding gypsum powder, dolomite, bentonite and calcium carbonate whiskers with one another to obtain mixtures, adding tap water into the mixtures and uniformly stirring the tap water and the mixtures to obtain slurry; adding plant fibers into deionized water to obtain first mixtures, ultrasonically dispersing the first mixtures, adding inorganic gel and modified graphite powder into the first mixtures to obtain second mixtures, heating and stirring the second mixtures, simultaneously adding water reducing agents, foaming agents and polyaryl ether ketone into the second mixturesto obtain third mixtures, then adding antibacterial agents and sodium tripolyphosphate into the third mixtures and continuously carrying out stirring reaction to obtain mixed slurry; sequentially pouring the slurry and the mixed slurry into molds to obtain green bricks and carrying out steam curing to obtain the antibacterial and abrasion-resistant aerated brick. The antibacterial and abrasion-resistant aerated brick and the method have the advantages that the calcium carbonate whiskers and the modified graphite powder are added, accordingly, the strength of the antibacterial and abrasion-resistant aerated brick can be improved, the toughness and the abrasion resistance of the antibacterial and abrasion-resistant aerated brick can be enhanced, and the service life of the antibacterial andabrasion-resistant aerated brick can be prolonged; the water reducing agents, the foaming agents, the antibacterial agents, the sodium tripolyphosphate and the polyaryl ether ketone are added, and accordingly the antibacterial property and the corrosion resistance of the antibacterial and abrasion-resistant aerated brick can be enhanced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an antibacterial and wear-resistant aerated brick and a preparation method thereof. Background technique [0002] Aerated bricks are aerated bricks produced by high-temperature autoclaved equipment, that is, bricks produced by various other processes including autoclaved. It is unique in that it is a very light thermal insulation Hot new building wall materials. The biggest advantage of aerated bricks is to save land resources, without wasting a lot of cultivated land. Its raw materials are widely used. Ash sand, slag, fly ash and coal gangue are all raw materials for aerated bricks. After mixing the raw materials into mortar, Then through the molding process to make aerated bricks. [0003] Aerated bricks have the advantages of light weight, good thermal insulation performance, strong shock resistance, good processing performance, and good sound insulation perform...

Problems solved by technology

Although the use of tailings, sea mud, fly ash, etc. to make aerated bricks is beneficial to environmental protection, compared with traditional raw materials, the aerated brick wall has weaker antibacterial ability, and paint and other coatings need to be applied to the surface of aerated bricks
