Description

A kind of baking-free water-permeable brick and preparation method thereof
Technical field
The invention belongs to floor tile preparing technical field, particularly a kind of baking-free water-permeable brick and preparation method thereof.
Background technology
Desulfurization slag is the waste residue produced in circulating fluidized bed (CFB) boiler desulfurization operation, because its particle is comparatively large, is settled down to furnace bottom, can obtains through slag-drip opening because wind speed is not enough to make its fluidisation.Desulfurization slag is trade waste, is one of industrial residue that the current discharge capacity of China is larger.Desulfurization slag has a kind ofly misplaced local resource, and Appropriate application desulfurization slag is a problem in the urgent need to address.
Traditional water-permeable brick is prepared into cellular concrete mainly with common rubble and forms, or is more senior polymer fiber concrete permeable brick, ecological husky base water-permeable brick etc.Be at present that the research that seepy material prepared by aggregate is left to be desired with desulfurization slag.
Patent 201110442054.X describes a kind of method utilizing sugared filter mud to prepare water-permeable brick, and the method is that thermal power plants flyash is main raw material, and clay makes binding agent, waste ceramic is aggregate in employing with industrial residue sugar filter mud for pore former.Raw material through batching, stir, the operation acquisition finished product such as old, shaping, dry, sintering.Above-mentioned water-permeable brick is main raw material with solid waste coal ash, but in preparation process, need sintering, makees binding agent, waste coal resources in a large number, damage to land with clay.Patent 201220733300.7 describes a kind of double-deck seepage brick utilizing slag and Desert Sand to do aggregate, and described seepage brick upper strata is the desert sand bed of Desert Sand and aqueous high molecular binding agent mixing compacting; Seepage brick bottom is the inorganic material layer being mixed compacting by slag, water and silicate cement, take full advantage of Waste Slag, but its binding agent adopted is one of aqueous epoxy resins, polyvinyl acetate resin, polyvinyl alcohol or combination, belong to macromolecular material, considerably increase preparation cost.
Summary of the invention
The object of this invention is to provide a kind of baking-free water-permeable brick and preparation method thereof, it is characterized in that, described baking-free water-permeable brick take desulfurization slag as aggregate, and cement is toughener and binding agent, Na 2siO 39H 2o and NaOH is exciting agent, mixes, normal temperature consolidated formation; Wherein, desulfurization slag accounts for 40 ~ 76wt.% of raw material total mass, and cement accounts for 20 ~ 50wt.% of raw material total mass, NaOH and Na 2siO 39H 2o accounts for 4 ~ 10wt.% of raw material total mass.
Described desulfurization slag proportioning is 30 orders: 40 orders: 50 object ratios of quality and the number of copies are 1:1:1 ~ 6:1:1.
Described NaOH and Na 2siO 39H 2the mass ratio of O is 1:1.
The preparation method of described baking-free water-permeable brick, is characterized in that, comprises step:
1) carry out stage treatment to desulfurization slag, obtain the desulfurization slag that grade is different, its grade is 30 orders, 40 orders and 50 orders;
2) by desulfurization slag different for grade in mass ratio proportioning be 30 orders: 40 orders: 50 orders=1:1:1 ~ 6:1:1, mixes;
3) NaOH and Na 2siO 39H 2o weighs for 1:1 in mass ratio, adds tap water and stirs, make it to dissolve completely;
4) account for 40 ~ 76wt.% of raw material total mass by desulfurization slag, cement accounts for 20 ~ 50wt.% of raw material total mass, NaOH and Na 2siO 39H 2the ratio that O accounts for 4 ~ 10wt.% of raw material total mass mixes;
5) be positioned in model by the compound of step 4), conveniently brickmaking compression molding, natural consolidation, maintenance at normal temperatures obtains finished product.
Described maintenance is to the water-permeable brick maintenance more than 28 days under wet environment and room temperature condition after shaping.
The invention has the beneficial effects as follows that achieve the second stage employ of resource, compared with vitrified brick, the present invention avoids sintering, has saved a large amount of coal resources with solid waste desulfurization slag for aggregate.There is good water-permeable and humidity-preserving type, city can be alleviated very well due to the municipal drainage pressure that caused by waterproof ground bedding and tropical island effect, be conducive to the water balance keeping city, the edatope of ground vegetation growth can be improved, regulate the eubiosis, can in the anti-skid on snow raising ground, sky.Realize save energy resource, reduce the discharge of solid waste, promote water cycle, improve the ecological environment.Be mainly used in the laying of the pavior brick of the public place such as walkway, square, gardens needing infiltration rapidly.
