Bacteriostatic autoclaved aerated concrete block capable of adsorbing peculiar smell and preparation method therefor

Abstract

The invention discloses a bacteriostatic autoclaved aerated concrete block capable of adsorbing peculiar smell. Bamboo fibers are subjected to an acetylation reaction, so that free hydroxyl groups in cellulose are sealed and the hydrophobic property and thermal stability of a material are improved; other effective components are added in combination with a physical modification method, so that the durability and dispersity of the fibers in autoclaved aerated concrete are improved; added jade powder improves the strength, apparent density and bacterial inhibition property of the block; added cassava dregs solve the problem of environmental pollution, replace the effect of gypsum, reduce production cost and realize the themes of saving energy, protecting the environment and turning waste into wealth; a process is simple, easy in operation and low in production cost; a product has the advantages of capabilities of inhibiting bacteria and adsorbing peculiar smell, high strength, low shrinkage rate and the like, and is low in self weight; and when the bacteriostatic autoclaved aerated concrete block is used as a building brick, the density of the bacteriostatic autoclaved aerated concrete block is only 1 / 3 of that of a clay brick, so that the self weight of a building can be greatly reduced, the service life of the bacteriostatic autoclaved aerated concrete block is synchronous with that of the building, and worries of secondary insulation and maintenance do not exist.

Description

technical field [0001] The invention relates to the technical field of aerated blocks, in particular to an antibacterial autoclaved aerated concrete block capable of absorbing peculiar smell and a manufacturing method thereof. Background technique [0002] As one of the important varieties of new wall materials, autoclaved aerated concrete blocks have many advantages such as good thermal insulation effect, good fire performance, sound insulation, light weight, and environmental protection compared with traditional clay fired bricks. However, the volume deformation coefficient of air-entrained concrete blocks is relatively large, the strength is relatively low, and the water absorption rate is high. When building a wall, the wall is prone to cracks, and the plaster layer is prone to large-scale cracks, hollowing and falling off. , showing obvious brittleness, which hinders the further application and promotion of autoclaved aerated concrete blocks to a certain extent. Fiber,...

Problems solved by technology

However, in the industrial production process of autoclaved air-entrained concrete blocks, steel wires are generally used to cut and shape the initially set air-entrained concrete, and the addition of too many fibers will affect the cutting of the air-entrained concrete, making the fibers The application effect in autoclaved aerated concrete is not particularly significant, which hinders its application range in autoclaved aerated concrete blocks, and also seriously affects the product quality and performance of autoclaved aerated concrete blocks
