Description
Technical field
The present invention relates to aerated bricks technical field, be specifically related to a kind of sound-absorbing aerated bricks and preparation method thereof.
Background technology
In recent years, along with the quickening of process of industrialization and the raising of the level of urbanization, also various environmental stresss and problem have been brought, the various solid wastes that Industrial processes produce and urban construction are removed and are remake the solid waste brought etc. and perplexing always resident's living environment, the present invention adds in aerated bricks solid waste as starting material, realize the cyclic utilization of waste, reduced the pollution to environment, met strategy of sustainable development requirement.
Aerated bricks is the air-entrained concrete building block of producing by autoclave at high temperature apparatus and process.Air-entrained concrete building block is take cement, slag, sand, lime etc. as main raw material, add foaming agent, the solid block forming through stirring moulding, steam press maintenance, gas concrete is by purposes, can be divided into five kinds, non-bearing building block, bearing building block, insulation block, wallboard and roof boarding.
Tradition solid clay brick weight is large, not only wastes outside national clay resource, price height, and cannot meet the requirement of some special buildings brick, and therefore common brick use has been completely forbidden in present many advanced areas, replaces and advocates energetically aerated bricks.Compare with normal concrete brick with traditional clay brick, aerated bricks is not only lightweight, also has heat insulating, an advantage such as sound-proofing properties is excellent, shock resistance is strong, good processability, resistance to elevated temperatures are good, strong adaptability.But China, about the production technology of aerated bricks is ripe not enough, makes aerated bricks Development Technology slow at present, also cannot meet the demand of multiple market.
Summary of the invention
Object of the present invention is just to provide a kind of sound-absorbing aerated bricks and preparation method thereof, to overcome the deficiencies in the prior art.

The preparation method of described a kind of sound-absorbing aerated bricks, is characterized in that comprising the following steps:
(1) agalloch eaglewood, anise are decocted together in water to filtration in 2-3 hour, gained filtrate vacuum concentration extracts, and obtains Chinese medical extract;
(2) after the filter residue of step (1) and iron ore tailings, molybdenum tailings, corn cob, corn stalk are mixed, at 650-800 ℃, calcine 3-4 hour, cooling, grind, add erythritol waste liquor, alkali lignin, guar bean flour to stir;
(3) by step (1), (2) reaction mass and other remaining component, drop in stirrer and be uniformly mixed 8-10 minute, obtain mixed slurry;
(4) gained mixed slurry is poured into the mold moulding, precuring 1-3 hour at 46-53 ℃, the demoulding, cutting, obtains building block base; Again building block base is put into reactor steam press maintenance 13-15 hour, put in storage and get final product.
The present invention has following beneficial effect: the present invention take iron ore tailings, molybdenum tailings as major ingredient, to have cost low, the feature such as easy to use; And added straw ash and the Chinese medicine slag after calcining modification, and there is germ resistance on the one hand, put forward on the other hand the sound insulation of aerated bricks, heat insulation and heat-insulating property, market outlook are wide.
