Antibacterial and mildewproof concrete aerated brick and preparation method thereof

Abstract

The invention discloses an antibacterial and mildewproof concrete aerated brick which is characterized by being prepared from the following raw materials in parts by weight: 200 parts of fly ash, 40-50 parts of talc, 50-60 parts of river sand, 20-25 parts of gypsum, 20-30 parts of neopentyl glycol, 20-30 parts of phthalic anhydride, 80-100 parts of methylbenzene, 1-2 parts of p-toluenesulfonic acid, 6-8 parts of calcium carbide, 20-30 parts of phosphoric acid, 6-8 parts of sodium lignin sulfonate, 25-30 parts of palygorskite, 3-5 parts of sodium citrate, 15-20 parts of alumina, 5-6 parts of tetraisopropyl titanate, 2-3 parts of fatty alcohol polyoxyethylene ether, sodium sulfate, 2-3 parts of chlorhexidine, 0.8-1 part of tea tree essential oil, 6-8 parts of magnesium stearate, 5-6 parts of barium stearate and a proper amount of water. The antibacterial and mildewproof concrete aerated brick prepared by the invention has excellent comprehensive technical properties such as heat preservation, thermal insulation, sound insulation, shock resistance, durability and the like.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an antibacterial and mildew-proof concrete aerated brick and a preparation method thereof. Background technique [0002] Concrete aerated brick has a special pore structure and contains a lot of air, so it has good heat insulation performance. In addition, it also has light weight, sound absorption and sound insulation, waste utilization, energy saving, good fire performance, nailable, It has the advantages of sawing, planing and anti-seismic ability, so it is widely used in the external wall enclosure of buildings and the insulation of internal and external walls. At present, the impermeability and corrosion resistance of the concrete aerated bricks prepared by the existing technology are generally not high, and they are prone to cracking, even breaking and collapsing under long-term water impact or strong corrosive environments. security risks.

Problems solved by technology

At present, the impermeability and corrosion resistance of concrete aerated bricks prepared by the existing technology are generally not high, and they are prone to cracking, even breaking and collapsing under long-term water impact or strong corrosive environment, which has great potential security risks

[0003] In the article "Experimental Research on Mud-Containing Siliceous Chips-Lime Aerated Concrete", the author Chen Youzhi and others used siliceous chips with different mud contents as siliceous materials to prepare B05 by hydrothermal synthesis reaction with lime-calcareous materials. , B06 grade air-entrained concrete, although the compressive strength of the air-entrained concrete obtained by this method has been improved, but the impermeability and corrosion resistance are still not high
