Abstract
The invention provides a smelting waste slag light composite artificial stone which comprises a main body material prepared from structural slurry. The structural slurry comprises a base material, a cementing agent, water, a polymeric additive, an alkaline excitant and a foamer aqueous solution or a foam material. A production method of the smelting waste slag light composite artificial stone comprises the following steps: by pre-treating the smelting waste slag which is used as part of cementing agent and base material, introducing the foamer aqueous solution or the foam material; stirring the components; and casting and carrying out vibration molding in a die. The stone provided by the invention is scientific in formula and reasonable in process and has ecological environmental protection property, high mechanical strength, low cost and excellent operating performance. The self weight of the smelting waste slag light composite artificial stone is reduced, and the heat preserving and insulating properties and the soundproof, fireproof and saltpetering-preventing properties of the smelting waste slag light composite artificial stone are improved. The stone has extremely strong durability and color stability in various severe conditions.
Description
Technical field
The present invention relates to a kind of melting waste slag lightweight composite artificial shone material and production method thereof.
Background technology
Melting waste slag lightweight composite artificial shone material, exactly by pretreatment, add functional additive, adopt that special process is produced has special construction and a function, can reduce carrying capacity of environment, improve with the phase Harmony of ecotope and there is the artificial stone-like material of light heat-insulating performance.
In melting waste slag to smelt the ratio maximum of slag.Slag is the byproduct producing in steelmaking process, and every 1 ton of steel approximately produces 0.1-0.14 ton slag.Within 2007, China's slag generation has reached 6,546 ten thousand tons, and is also increasing progressively every year, and utilization ratio is only 10%, and most slags are still thrown aside, and not only take farmland and contaminate environment.The main outlet of the extensive resource utilization of slag is exactly as cement raw material and concrete base-material, as Chinese patent CN102093011A discloses a kind of baking-free building block brick that utilizes large industrial residue to prepare.
The low major cause of steel slag utilization rate is because slag stability is bad at present, has affected its normal use on engineering construction.The factor that affects slag stability is a lot, be mainly due in steelmaking process for imurity-removal, often add high calcium, high magnesium material to make slag former.Along with the shortening of tap to tap time, calcium oxide in slag and magnesium oxide can not fully react with compositions such as silicon-dioxide, form free calcium oxide (f-CaO) and free magnesium (f-MgO) is present in slag, making especially f-MgO of building materials or engineering materials, the time that it is cleared up at normal temperatures is completely 20 years, and road, buildings or the building material made that causes for above-mentioned reasons using slag to be raw material destroys because of cracking.But pass through to smelt pre-treatment, the introducing suitable additive of slag in artificial stone-like material field, and control the size of product, can evade well this technological difficulties.
Summary of the invention
The present invention solves the aforementioned problems in the prior proposition, its objective is a kind of melting waste slag of component proportion science lightweight composite artificial shone material is provided.
