Description
Technical field
The invention belongs to construction material classes, and in particular to it is a kind of using iron tailings preparation porous thermal insulating ornament materials and its
Preparation method.
Background technique
With the rapid development of steel and iron industry, the wastes total amount such as tailing generated during iron ore exploitation up to 2,000,000,000 t,
Not only stacking process occupies a large amount of soils, but also since mill tailings has been milled to 0.15mm even 0.07mm hereinafter, therefore more
When being stored at being discharged into river, mountain valley, low land in tailing dam or nearby, often meeting seepage flow overflows, and fugitive dust of blowing forms sandstorm
And serious polluted source, soil and air, deteriorate life and the working condition of surrounding area, is brought sternly to human habitat
Heavily contaminated and harm；The harmful components in tailing and remaining beneficiation reagent can also cause ecological environment seriously to endanger simultaneously
Evil.The chemical component of iron tailings is mainly the oxide based on SiO2 and Al2O3, close to building ceramic material, glass, brick
Ingredient required for watt equal, can be used for substituting the raw material in construction material.
With the proposition of 65% target of building energy conservation, more and more attention has been paid to utilize iron to energy-saving and heat-insulating material at the same time
Tailing, which prepares thermal insulation material there has also been sizable progress, such as Xi'an materials for wall research institute patent publication No., is
The Chinese patent application of CN101638918A discloses one kind using iron tailings and natural material shale as primary raw material, adds toughening
The method that agent, fluxing agent and foaming agent prepare thermal insulation material using traditional kiln sintering process, Wuhan University of Technology's Publication No.
The Chinese patent application of CN102167618A discloses a kind of flyash-iron tailings base porous insulation material and preparation method thereof,
It is mixed by powdery solid waste, binder, fluxing toughener and composite foamable agent.Material made from above two method
Although expecting that heat insulation effect is preferable, still need to improve its decorative effect using various coating, leads to complicated construction technique, metope decorations
Surface layer durability is poor.Shanghai Simike Building Ceramics Co., Ltd Publication No. CN2578450Y discloses a kind of crystallite glass
Glass ceramics vitrified brick composite board, it is first once-firing vitrified tile green body, is then laid with one layer of crystallite on the surface of vitrified tile
Glassy layer carries out twice firing, its surface is made to have the effect and quality of devitrified glass brick, and has the quality of vitrified tile inside,
But its do not consider may by glass-ceramic layer and vitreous brick layer thermal expansion coefficient it is different brought by problem of Cracking,
And this method uses double sintering, and technique is relative complex.
Other than being sintered class thermal insulation material, External Thermal Insulation Technology for External is also increased substantially, and is up to the present formed
EPS sheet thin-coat plaster system, EPS heat-insulating mortar outer heat preservation system, hard-foam polyurethane heat-insulation system and rock wool board heat-preservation system
The outside wall heat preservation system of equal comparative maturities.Although organic external thermal insulation system has preferable function of heat insulation, deposit
In very big safety problem, mainly since thermal insulation material used is high molecular polymer, easily cause exterior wall heat-preserving system
Burning.And with the extension of use time, the problem of organic insulation material also faces aging, Large Area Cracking easy to form,
It falls off and plays drum.
Summary of the invention
It is a kind of using iron technical problem to be solved by the present invention lies in view of the deficiency of the prior art, providing
The porous thermal insulating ornament materials and preparation method thereof of tailing preparation, making the material not only has lightweight and preferable heat insulation effect, but also
It is smooth with surface, there is a lower water absorption rate, the effect of water-proof decorative, and at high temperature through microwave calcination, once sintered
It forms and is completely embedded, no delamination splitting phenomenon.
To achieve the goals above, the technical scheme is that using iron tailings prepare porous thermal insulating ornament materials,
It is characterized in that it is by forming after solid mixed powder and water mixing granulation through microwave sintering, including porous insulating layer and glass surface dress

The method for preparing porous thermal insulating ornament materials using iron tailings, it is characterised in that it includes the following steps:
1) iron tailings ball milling, screening are obtained the iron tailings powder of fineness < 100 μm, while cullet is broken using ball mill
Broken, grinding is under 100 μm；
2) iron tailings powder 75%~85% by mass percentage, foaming agent 2%~10%, fluxing agent 0.1~1%, foam stabilizing
Agent 0.1~9%, the requirement of absorbing material 1~5% measure various raw materials, and it is total that it is added with batch mixer to dry powder after mixing
12%~15% clear water water spray of quality, which is granulated, is used as porous insulating layer raw material；By mass percentage iron tailings powder 45%~
75%, waste glass powder 20%~50%, thickener 1%~10%, swelling agent 1~5%, color adjust material 1~5%, inhale wave
The requirement of material 1~3% measures various raw materials, it is added to the 12%~15% of dry powder gross mass after mixing with batch mixer
Clear water water spray be granulated be used as glass surface decorative layer raw material；By uniformly mixed porous insulating layer raw material and glass surface decorative layer raw material
It is aged 2d~15d in closed space, is sufficiently homogenized；
3) first porous insulating layer raw material being laid in mold and being vibrated keeps its smooth, then glass surface decorative layer raw material is laid on more
The compression moulding under 10~30Mp pressure on the insulating layer raw material of hole, dry 18 under natural conditions~for 24 hours, it places into drying box and exists
Dry 6~8h, is then placed in micro-wave oven to 700~1000 DEG C of once sintered moldings, natural cooling simultaneously takes off at 105~115 DEG C
Mould.

Warm heat-insulated and decorative encasing double effects.Which solve be easy to fall off brought by thermal insulation material and finishing material distributing installation,
The disadvantages of complex process, simplifies preparation process, also plays certain economic benefit；
2, the present invention uses iron tailings for primary raw material, and iron tailings utilization rate is up to 85% or more, and benefit is evident for emission reduction, system
Standby process energy conservation environmental protection；Preparation process uses the once sintered molding of microwave, utilizes equally distributed suction wave material natural in iron tailings
Expect iron oxide, effectively raise microwave absorption efficiency, but also homogeneous heating, stable, performance excellent to obtain quality
Material provides effective process means；It is using another major reason of microwave sintering: due to insulating layer and decoration layer component
Difference so that the sintering temperature of decorative layer will be lower than insulating layer, to use conventional sintering process, decorative layer will prior to protect
Warm layer sintering, causes decorative layer burning, and this method passes through the suitable absorbing material of addition, so that the absorbing material in insulating layer
Less than decorative layer, during microwave sintering, aloow insulating layer and decorative layer reach sintering temperature simultaneously, avoid because
It cracks caused by sintering temperature is different；
3, the present invention increases decorative layer high-temperature liquid-phase viscosity, one by the way that a certain amount of thickener is added in decorative layer
So that the gas in insulating layer will not escape on surface, avoids surface and form stomata, the two also can guarantee will not be because of temperature
It is excessively high and cause melt liquid phase collapse, influence product appearance；
4, the present invention makes insulating layer and decorative layer dilation one by the way that a certain amount of swelling agent is added in decorative layer
It causes, avoids thus caused problem of Cracking.
