Abstract

A self-cleaning water permeable brick manufactured from rare earth fine tail sand is disclosed. Peanut vines are carbonized and then ground at room temperature. Pore surfaces adsorb a photocatalytic material that is nanometer titanium dioxide. Hydroxyl free radicals, super-oxygen ion free radicals and H2O free radicals are generated during light irradiation, have strong oxidation and degradation capabilities, can directly oxidize various organic matters into CO2, H2O and other inorganic small molecules, can degrade automobile exhaust in air when being used in the water permeable brick, have high adsorbability, and can effectively clean pollutants in water. Modified sugar filtration mud is adopted as a pore-forming agent. The rare earth fine tail sand, blast furnace slag and coal gangue are adopted as aggregates so that reutilization of rear earth waste resources is achieved and the self-cleaning water permeable brick having good water permeability, good water-retaining properties and high strength is obtained, thus facilitating environment protection, and promoting industrial and regional economic and urbanization development.

Description

A kind of automatically cleaning water-permeable brick prepared with the thin tailings of rare earth and preparation method thereof
Technical field
The present invention relates to building material technical field, particularly relate to a kind of automatically cleaning water-permeable brick prepared with the thin tailings of rare earth and preparation method thereof.
Background technology
Along with the continuous plaque of city water resource is weary, and the pursuit of urban environment hommization, the research and development of water-permeable brick cause material, environment and the extensive concern of municipal works expert.Water-permeable brick has good seepage of water and moisture retention, can well alleviate city and cover, owing to being mated formation by non-pervious surface, " the city desertification " and " tropical island effect " caused, urban waterlogging can also be alleviated to a certain extent, supplement urban groundwater, regulation urban environment, is conducive to keeping city water balance.Existing water-permeable brick develops to high compact, high intensity direction, its comprcssive strength is higher, but still there is many defects, on the one hand it is that water penetration is excessively poor, even if there being the fragment of brick that water permeability is good, but its comprcssive strength does not reaches paving requirement, water-permeable brick is through life-time service simultaneously, surface and hole are easy to fall into various dirt and form blocking and can not automatically remove, weakening permeable effect, ecological effect is poor, and higher to the requirement of pumping equipment in use, occur as run into the situation of impeded drainage after rain, be then easily generated hydrops problem.The water-permeable brick function that the most existing technology produces is the most single, and they are simply to make precipitation pass through brick body to permeate the ground, it is impossible to effectively remove contained pollutant in water, the sewage through brick body is not had purification.For solving these problems, need to develop a kind of novel while there is permeable and purification function automatically cleaning water-permeable brick.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of automatically cleaning water-permeable brick prepared with the thin tailings of rare earth and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of automatically cleaning water-permeable brick prepared with the thin tailings of rare earth, is prepared by the raw materials in: rare earth thin tailings 32-34, blast-furnace cinder 20-22, gangue 13-15, cement 11-13, sugar filter mud 19-21, osseocolla powder 3-5, zinc phosphate 1.6-1.8, cetyl trimethylammonium bromide 2.1-2.4, Petiolus Trachycarpi oil 5-7, nano titanium oxide 0.7-0.9, charred Folium Artemisiae Argyi 4-6, seedling of Semen arachidis hypogaeae 2-4, suitable quantity of water.
The manufacture method of described a kind of automatically cleaning water-permeable brick prepared with the thin tailings of rare earth, comprises the following steps:
(1) seedling of Semen arachidis hypogaeae is dried put in retort at a temperature of 450-500 DEG C, isolation air carbonization 20-30 minute, it is cooled to room temperature and adds nano titanium oxide, charred Folium Artemisiae Argyi, palm oil mill 40-50 minute, dry；
(2) dry at a temperature of 50-60 DEG C after sugar filter mud being washed, send into and high-speed mixer adds cetyl trimethylammonium bromide, zinc phosphate and appropriate water, turning/speed high-speed stirred 15-20 minute of min with 1400-1500, be dried, ultrasonic grinding becomes powder to dry；
(3) thin for rare earth tailings, blast-furnace cinder, gangue are crushed to 120-140 mesh after 690-740 DEG C of high-temperature calcination processes, add step (1), (2) material and the mixing of other residual componentss, putting into ball milling 2-3 hour in ball mill, water spray pelletize, ageing are pressed into raw adobe after 2 days；
(4) life adobe natural drying is air-dried, sinter 1-2 hour in 1060-1100 DEG C in chamber type electric resistance furnace, naturally cool to room temperature discharging.
The invention have the advantage that the present invention after seedling of Semen arachidis hypogaeae carbonization is processed through grinding at room temperature, pore surface adsorption photochemical catalysis material nano titanium dioxide, generation hydroxyl radical free radical, Superoxide anion free radical and H when light irradiates2O free radical is respectively provided with the strongest oxidation, capacity of decomposition, is CO by various Organic substance direct oxidations2And H2The inorganic molecules such as O; it is applied in water-permeable brick be possible not only to the vehicle exhaust etc. in air of degrading; also there is stronger adsorptivity; can effectively purify the pollutant in sewage; the present invention is with modified sugars filter mud as pore former; the thin tailings of rare earth, blast-furnace cinder, gangue are aggregate; while realizing rare earth waste resource regeneration; obtain there is good water penetration and water-retaining property, automatically cleaning water-permeable brick that intensity is high, thus beneficially environmental conservation promote the development of industry and regional economy and Urbanization Construction.
