Abstract
The invention discloses a method for preparing aerated bricks by utilizing ceramic waste, and the method comprises following steps of (1) mixing raw materials according to the following dry basis in parts by weight: ceramic waste after being ground, quicklime, cement and the like; (2) placing water according to 85 to 95 percent of the mass of the mixed raw material dry base in step (1), placing waste aluminum powder according to 0.01 to 0.03 percent of the mass of the mixed raw material dry base, placing plaster according to 9 to 11 percent of the mass of quicklime, and placing peregal which is 1 to 4 percent of the mass of aluminum powder; and (3) the slurry after being stirred in step (2) is foamed for 30 to 40 minutes under the temperature of 60 to 80 DEG C. Due to the adoption of the method, the consumption of ceramic waste is vast, energy conservation and environmental protection can be realized, the environmental pollution problem caused by the stacking treatment of the ceramic waste can be alleviated, and simultaneously new raw material source can be supplied for the hollow bricks.
Description
Technical field
The present invention relates to building material field, specifically belong to a kind of method of utilizing ceramic waste material to prepare aerating hollow brick.
Background technology
Along with the fast development of social economy and ceramic industry, ceramic industry waste material is increasing, it is not only exerted heavy pressures on to urban environment, but also has limited the development of urban economy and the Sustainable development of ceramic industry, thus the processing of ceramic industry waste material with utilize extremely important.At present, the processing of China's ceramic industry waste material with utilize degree lower, funds shortage, causes a large amount of waste residues to tie up arable land, and water and air is polluted.The particularly high speed development of nearly 20 years, ceramics is along with the increase of output, the quantity of waste material is more and more, according to incomplete statistics: only Foshan Ceramic producing region, the annual production of various ceramic waste materiaves has exceeded 4,000,000 tons, and national ceramic waste material { TodayHot} annual production is estimated 1,000 ten thousand tons of left and right, so a large amount of ceramic waste materiaves has not been the soluble problem of simple landfill, and along with the growing and social progress of economy, environment has become the focus that people pay close attention to, the accumulation of ceramic waste material ties up soil, affect the dust content of local air, and the landfill labor intensive material resources of ceramic waste material, also polluted underground water matter, how to turn waste into wealth, change waste material is resource, become the task of top priority of science and technology and environmental administration.
For a long time, the comprehensive utilization of ceramic waste material is a global problem always, although the comprehensive utilization of ceramic waste material has been carried out to a large amount of research both at home and abroad, due to various reasons technical and economically, great majority are not put to industrial realization.
Described in comprehensive, with ceramic waste material, be that auxiliary material is produced cement, wall body brick, pavement material and had been reported, the production that is used for aerated-block using ceramic waste material as main raw material have not been reported.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing ceramic waste material to prepare aerating hollow brick, ceramic waste material consumption is large, energy-conserving and environment-protective, alleviates ceramic waste material and stores up the problem of environmental pollution that processing brings, simultaneously for hollow brick provides new raw material sources.
Technical scheme of the present invention is as follows:
Utilize ceramic waste material to prepare a method for aerating hollow brick, it is characterized in that carrying out in accordance with the following steps:
(1), by following butt mass parts mixing raw material:
Ceramic waste material 55-70 part after pulverization process
River sand 20-30 part
Unslaked lime 10-15 part
Cement 8-10 part
Lignocellulose 0.5-2 part
Redispersible latex powder 2-5 part
(2), by the 85-95% of above-mentioned steps (1) mixing raw material butt quality, add water, the 0.01-0.03% of mixing raw material butt quality adds aluminium scrap powder, 0.1-0.4% methylate ether of cellulose, 1-2% and adds epoxy Toenol 1140, the 20-30% of Lime Quality adds gypsum, and the 1%-4% of aluminium powder weight adds peregal;
(3), by above-mentioned steps (2) stir after slurry at 60-80 ℃ of temperature, foamed time 30-40min;
(4), the vapor cure under normal pressure of the foamed slurry of above-mentioned steps (3) is obtained to green compact, and cut into corresponding size;
(5), by the green compact of above-mentioned steps (4) at 0.8-0.9Mpa vapor cure 18-22h, obtain aerating hollow brick finished product.
The useless building waste of described utilization is prepared the method for aerating hollow brick, it is characterized in that: in step (2), add soda ash, add-on is in every cubic metre of mixed slurry, to put 3-4kg soda ash.
The present invention compared with prior art tool has the following advantages:
Compared with other building blocks, the aerated-block unit weight that the present invention produces is light, and intensity is high, and the bearing wall or the interior wall partition that are specially adapted to Highrise buildings are used.
Compared with aerated-block, main raw material of the present invention is ceramic waste material, is conducive to solve ceramic waste material and stores up the problem of environmental pollution of processing and bring.
In a word, the practical situation that the present invention is large in conjunction with China's ceramic waste material amount, utilization ratio is low, product performance meet load-bearing for building and non-lbearing wall material specification of quality.Building block main raw material(s) is ceramic waste material, and usage quantity is large, is conducive to solve ceramic waste material and stores up the problem of environmental pollution of processing and bring, for the recycling of ceramic waste material has been opened up a new approach that utilizes.
