Aerated concrete block capable of adsorbing toxic and harmful gases and preparation method of aerated concrete block

Abstract

The invention discloses an aerated concrete block capable of adsorbing toxic and harmful gases and a preparation method of the aerated concrete block. The aerated concrete block is prepared from the following raw materials in parts by weight: 42-68 parts of yellow sands, 10-15 parts of nano black stones, 12-16 parts of a zeolite molecular sieve, 18-26 parts of allophone, 22-28 parts of wood dust, 15-20 parts of ground calcium carbonate powder, 26-34 parts of sea mud, 16-22 parts of attapulgite, 10-15 parts of alpha type semi-hydrated gypsum, 3-6 parts of carbomer resin, 1-2 parts of modified aluminum powder, 2-3 parts of sodium thiosulfate, 2-3 parts of zinc sulfate and 1-2 parts of azodiisobutyronitrile. The substances including the nano black stones, the zeolite molecular sieve and the like with outstanding physical adsorption functions are added into the aerated concrete block disclosed by the invention, so that the aerated concrete bock can adsorb harmful gases of formaldehyde, benzene compounds, sulfur oxide, nitrogen oxide, carbon monoxide, hydrogen sulfide, ammonia, isovaleric acid, methyl mercaptan, trimethylamine (fishy), TVOC (total volatile organic compounds) and the like to achieve a function of purifying air; and meanwhile, the aerated concrete block has the characteristics of high strength, good heat insulation and heat preservation properties, good sound isolation effect, heat resistance, moisture resistance, acid and alkali corrosion resistance and the like, and has a broad market prospect.

Description

technical field [0001] The invention relates to an aerated block capable of absorbing toxic and harmful gases and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Aerated blocks are made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) and calcareous materials (lime, cement, etc.) Pores are formed by chemical reactions, and porous silicate products are made through casting molding, pre-curing cutting, autoclaving curing and other processes. Aerated blocks have the characteristics of light weight, thermal insulation, good machinability, wide source of raw materials, high production efficiency, and low production energy consumption. They are widely used in load-bearing, enclosure, and filling of industrial and civil buildings. The general attention of various countries has become the preferred building material that many countries vigorously promote and develop. With the rapid development of...

Problems solved by technology

With the rapid development of my country's construction industry, the performance requirements for aerated blocks are getting higher and higher. However, traditional aerated blocks do not have the function of absorbing toxic gases and purifying air, and cannot meet people's higher requirements for environmentally friendly life.
