Abstract
The invention provides a preparing method of foamed ceramic. The foamed ceramic is prepared by evenly mixing high-temperature iron making slag and silicon powder and then adding a foaming agent to carry out foaming at 800-1200 DEG C. According to the foamed ceramic, foaming is carried out by using the waste heat of the high-temperature iron making slag, the process of cooling, smashing and then heating in the traditional foamed ceramic preparing process is omitted, waste of energy is completely eradicated, the problem of energy consumption in the traditional foamed ceramic preparing process is solved, and cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of foamed ceramic and preparation method thereof, be specifically related to a kind of low cost foamed ceramic and preparation thereof
Method.
Background technology
Regulation in " civil buildings outer heat preservation system and decoration of exterior wall fire prevention temporary provisions ": civil buildings heat insulating material for external
Combustibility is easily A level, and not lower than B2 level, and foamed ceramic is unexpected except the premium properties having quartz glass, also has
Excellent heat-insulating property and lighter weight, be to compare popular a kind of building thermal insulation material and external wall decorative material in recent years.
Foamed ceramic is using potter's clay mine tailing, potsherd, riverway sludge etc. as primary raw material, through foaming technique high temperature
The closed pore ceramic material of the high porosity of roasting, it is adaptable to the exterior-wall heat insulation of building, fire-blocking belt, building self-heat conserving
The fields such as cold-heat bridge process, foamed ceramic has that fire protection flame retarding, deformation coefficient be little, aging resistance, steady performance, Er Qiefa
The bubble ceramic ecological feature of environmental protection is preferable, good with plinth course and the compatibility wiped one's face, and safety and firmness is high, can the longevity same with building
Life, and compared with traditional organic material, foamed ceramic has the most ornamental and ageing resistance.
Chinese invention patent CN201410557401 discloses the preparation method of a kind of high purity quartz foamed ceramic, by dioxy
After SiClx uniformly mixes with silicon carbide micro-powder, make under vacuum or argon gas atmosphere medium and high temperature quartz foamed glass, then, then
Quartz foamed glass heat treatment generation crystallization is made high purity quartz foamed ceramic, but the preparation process of this foamed ceramic
In, needing high temperature and vacuum or the condition of coughing of argon atmospher, energy consumption is high, and cost is high so that the foamed ceramic cost prepared raises,
Reach about 200 yuan/side so that building invisible cost is obviously improved.
Summary of the invention
For problem above, foamed ceramic of the present invention and preparation method thereof.
Each component of the foamed ceramic of the present invention and mass fraction thereof be:
Ironmaking slag 60 ~ 80
Silica flour 20 ~ 40
Foaming agent 5 ~ 10.
Described ironmaking slag is high temperature ironmaking slag.
Described silica flour is quartz sand powder.
Described foaming agent is volcanic rock.
Described volcanic rock is material from acidic volcanic glass rock.
The preparation method of the foamed ceramic of the present invention is:
(1) in high temperature ironmaking slag, add room temperature silica flour to stir；
(2) gained mixture in step (1) is added in foam box, add foaming agent and stir, stand foaming.
Step (1) also includes that stirring is cooled to 1200 ~ 1300 DEG C.
The blowing temperature of step (2) is 800 ~ 1200 DEG C, and foamed time is 3 ~ 18 hours.
The foamed ceramic of the present invention, using high temperature ironmaking slag is primary raw material, is directly added into room temperature shape silica flour, utilizes height
Silica flour is preheated by the waste heat of temperature ironmaking slag, while stirring, have adjusted temperature and reaches the preference temperature that foams
1200 ~ 1300 DEG C, eliminate cooling and pulverize the process heated up again, stopped the waste of the energy, and solved tradition foamed ceramic
Energy consumption problem in preparation process, significantly reduces cost, and from 200 yuan/side, the cost of manufacture of foamed ceramic is reduced to 50
Unit/side, has high economic benefit.
