Abstract
The invention discloses an air-added brick which takes cullet as a substrate and a method for processing the air-added brick. The air-added brick comprises the following raw materials in part by weight: 40 to 55 parts of cullet, 5 to 10 parts of municipal sludge, 5 to 8 parts of cement, 5 to 10 parts of mica powder, 14 to 16 parts of expanded perlite, 4 to 5 parts of gypsum, 2 to 4 parts of modified potash, 0.03 to 0.05 part of aluminum powder, 0.5 to 1 part of palygorskite, 0.03 to 0.04 part of peregal, 0.03 to 0.05 part of soda, 0.01 to 0.02 part of aluminum hydroxide, 0.01 to 0.02 part of triethanolamine and 0.3 to 0.5 part of chitosan. Environmental pollution is effectively reduced by using the cullet and urban glass as ingredients of the air-added brick, waste materials are recycled, and the environment is protected; energy consumption is reduced; the air-added brick has higher heat insulation performance and sound insulation performance compared with the conventional air-added brick; and meanwhile, by optimizing a formula and the raw materials, the strength and the freezing resistance are obviously improved.
Description
Technical field
The present invention relates to building material field, specifically belong to a kind of aerated bricks and working method thereof taking glass cullet as matrix.
Background technology
Aerated bricks is the aerated bricks building block of producing by autoclave at high temperature apparatus and process, adopt the brick product of other the various explained hereafter including steam pressure, aerated bricks is a kind of novel wall material, its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating, and that this technology of China starts is more late, totally fall behind 40 years than abroad, but, the development of the aerated bricks industry of China is really very fast, and domestic aerated bricks technical matters level can reach international most advanced level now.
Aerated bricks sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and the source of its raw material very extensively, dust and sand, slag, flyash and coal gangue etc. are all the starting material that do aerated bricks, and very superior of the performance characteristics of aerated bricks, have extraordinary can working ability and heat insulation and insulated capacity, and very strong of plasticity-, have extraordinary processing characteristics, the research of aerated bricks raw material and processing technology need further to improve.
Summary of the invention
The object of the present invention is to provide a kind of aerated bricks and working method thereof taking glass cullet as matrix, glass cullet consumption is large, energy-conserving and environment-protective, alleviates glass cullet and stores up the problem of environmental pollution that processing brings, simultaneously for aerated bricks provides new raw material sources.
The present invention adopts following technical scheme to achieve these goals:
Aerated bricks taking glass cullet as matrix, the weight part of its constitutive material is: glass cullet 40-55, municipal sludge 5-10, cement 5-8, mica powder 5-10, pearlstone 14-16, gypsum 4-5, modification plant ash 2-4, aluminium powder 0.03-0.05, attapulgite 0.5-1, peregal 0.03-0.04, soda ash 0.03-0.05, aluminium hydroxide 0.01-0.02, trolamine 0.01-0.02 and chitosan 0.3-0.5.
The working method of the aerated bricks taking glass cullet as matrix, comprises the following steps:
(1) raw-material processing: starting material comprise glass cullet, municipal sludge, cement, mica powder, pearlstone, gypsum, modification plant ash and aluminium powder; Be crushed to fineness and reach 180-200 order;
(2) stir: first add water and stir separately, then mix and blend also adds other surplus stocks in raw material by weight;
(3) cast: the slurry that step (2) is stirred adds in stock mould, obtains brick idiosome;
(4) rest: the brick idiosome of step (3) is put into the chamber of resting, the chamber sealing thermal insulation 42-48 DEG C that rests, time 1-3 hour rests;
(5) cutting: the brick idiosome that step (4) is rested is put into and is processed into certain desired size on cutting machine;
(6) steam-cured: the green compact of above-mentioned steps (5), at 0.7-0.9Mpa vapor cure 17-20h, are obtained to aerated bricks finished product.
Modification plant ash is that plant ash is ground to form to 100-200 order powder, admixes that to be equivalent to the calcium lignin sulphonate agitating with octyl epoxy stearate, 1-2% of powder weight 1-2% even, dries, and is ground into powder and obtains.Beneficial effect of the present invention:
The present invention, by adopting glass cullet and city glass as the composition of aerated bricks, has effectively reduced environmental pollution, turns waste into wealth, and has protected environment; Reduce energy consumption; Aerated bricks of the present invention is heat insulation all good with sound-proofing properties, and more existing aerated bricks is significantly improved; The present invention is simultaneously by optimization of C/C composites materials, and intensity of the present invention, frost resistance are significantly improved.
