Abstract
The present invention relates to architectural decoration materials, particularly to steel slag marble and a making method thereof. The marble is composed of the following ingredients: 2 to 8% of steel slag powder of a specific surface area larger than or equal to 450mm<2>/kg, 30 to 60% of steel slag of a particle diameter smaller than or equal to 0.5mm, 25 to 45% of steel slag of the particle diameter of 2.5 to 3mm, 5 to 20% of stone powder additive and 2 to 8% of bonding resin, and the ingredients are pressed by a shaper after being mixed and stirred. Because steel slag molding sand is used as main materials by the present invention, the steel slag which is waste materials originally is sufficiently used. Through a test, the steel slag marble has the advantages of stable performance without radioactive pollution, pure color and lustre and high hardness, and can be widely used for architectural decoration engineering.
Description
Technical field
The invention belongs to the building and ornament materials production field, relevant with the marble in the building and ornament materials, relate to a kind of slag marble and preparation method thereof.
Background technology
Marble of the prior art mainly contains kinds such as natural marble and artificial marble, and natural marble is very expensive because of its resource-constrained price.Artificial marble can be classified as polyester type and inorganic type two big classes, and polyester artificial marble is mixed by macromolecular material such as unsaturated polyester and inorganic materials, again through suitably handling and get, this marble intensity height, but easily wear out, yielding, cost is higher.The mineral-type marble can be divided into sintered type and silicate-type two classes again, sintered type is that plagioclase, quartz, brightness English, christobalite powder and mixing such as ground hematite and part kaolin are prepared blank with puddling, with half-dried platen press moulding, high temperature burns and forms to about 1000 ℃ in kiln, this marble raw materials cost is low, but the cost height, energy consumption is big, and product is frangible.The silicate-type marble is to be agglutination material with cement or the levigate sand of lime, sand is thin aggregate, crushed marble, broken grouan, thin slag, nickel slag, industrial wastes such as blast furnace slag are coarse aggregate, through batching, stirring, moulding, pressurization, steam-cured, surface treatment such as polishing again makes, this marble cost is low, but corrosion resistance nature is relatively poor, also is prone to be full of cracks.In recent years, also occurred on the market with cement be base-material and be equipped with mineral filler artificial marble, although improve to some extent on the performance, but still because of its price factor, make that the cost of engineering construction is soaring significantly.
Along with the continuous quickening of process of industrialization, environment protection has become human key subjects that faced.Along with continuing to increase of resource, environment protection dynamics, the continuous lifting of output of steel in addition, the processing of waste one bessemer furnace slag of steel-making have become a big outstanding difficult problem of various countries' environmental improvement.How making bessemer furnace slag become a kind of important substance of resource utilization, is the target of the common pursuit of institute all the time of the human second half in last century.
The slag molding sand is the bessemer furnace slag that is in meltbility high-temperature liquid state, semi liquid state that steel-making is produced, formed shrend slag or cylinder slag after water spray, water filling cooling, carry out that deep processings such as magnetic separation, fragmentation, screening form, its most size distribution are in 0～50mm again.Characteristics such as the slag molding sand has stable performance, and quality is hard, and free calcium oxide and metal Ferrum content are low, be suitable as very much marmorean main material, but because many-sided factors such as fund, technology, by the end of at present, the slag molding sand does not obtain fully and effectively utilizing as yet.
Summary of the invention
For overcoming the defective on prior art marble resource and the price and the deficiency of the slag molding sand utilization of resources, the invention provides a kind of slag marble and preparation method thereof, to develop new marble raw material resources, it is low to make a kind of cost, the artificial marble that physical and chemical performance is good further improves the effective rate of utilization of steel slag resource.
The technical solution adopted for the present invention to solve the technical problems:
A kind of slag marble, its substantive distinguishing features is: described marmorean consisting of (weight percent): specific surface area is more than or equal to 450m
2The steel-making slag powder 2～8% of/kg, grain are through the slag 30～60% smaller or equal to 0.5mm, and grain is through being the slag 25～45% of 2.5～3mm, and particle diameter is the following stone flour additive 5～20% of 0.15mm, binding resin 2～8%.
In the marmorean composition of described slag, the iron-holder of its slag is smaller or equal to 1%.
The marmorean making method of a kind of slag, it is more than or equal to 450m with 2～8% specific surface areas
2The steel-making slag powder of/kg, 30～60% through be 0.5～0.9mm slag, 25～45% through be slag, 5%～20% particle diameter of 2.5～3mm be below the 0.15mm the stone flour additive mix with 2～8% binding resin and stir after the shaper compacting forms;
Concrete operation method is:
(1) ratio according to prescription weighs up the marmorean various components of slag with the measurement instrument classification, and is respectively charged in the different vessels;
(2) in same container, successively fully stirred 3～8 minutes, add binding agent again and fully stirred 3～6 minutes by thin, thick;
(3) will expect through the mixing after stirring and according to dimensional requirement mixed material evenly be shakeout in the mould;
(4) mixed material that shakeouts is put into the vibration press and vibrated, make its even structure, make its structure tight through being forced into 18～22Mpa again;
(5) after the demoulding, dried in the shade at normal temperatures 18～26 hours;
(6) carry out machine finish, water mill and skin patching;
(7) its surface is polished;
(8) according to the dimensional requirement of desired product it is cut out and cut.
Compare with traditional marble, the present invention has the following advantages:
1,, makes originally to be fully utilized for the slag of waste because the main component of this product is a slag.Compare with natural marble, have the advantage on the resource; Compare with artificial marble, have the advantage on the cost.
2, through check, slag marble of the present invention is compared with natural marble and artificial marble, and except that water-intake rate is inferior to the natural marble slightly, all the other every performance index all are better than artificial marble.The "dead" pollution of product, and stable performance, color and luster is pure, and the hardness height can be widely used in the building decoration engineering.
