The preparation method that above-mentioned environmental protection is non-burning brick, comprises step as follows:
(1) by building waste, cinder, phosphogypsum respective pretreatment, pretreated building waste, cinder, phosphogypsum is obtained;
(2) building waste after pulverizing, cinder, phosphogypsum and flyash, cement, water, Sodium Silicofluoride, frostproofer are mixed in proportion stirring evenly, obtain mixture;
(3) mixture is being vibrated under the dual function with pressure, obtained adobe;
(4) by adobe row piling natural curing, or directly put into steam curing shed and carry out piling low pressure steam-cured one day, place 20-28 days and get final product.
The present invention is preferred, and described natural curing is obtained adobe is delivered to stacking district carry out piling, the adobe piled up, and carries out watering maintenance after 8-12 hour, and every 3-5h maintenance once, between adobe preserving period, keeps brick body moistening, naturally places after maintenance 7-10d.
The present invention is preferred, described low pressure is steam-cured comprises preheating, intensification, constant temperature and cooling four-stage, described preheating temperature is 30��50 DEG C, warm up time 12-16h, leading to the steam 1.0-1.5h into 80��90 DEG C after preheating and carry out hyperthermic treatment, constant temperature 90��92 DEG C keeps 3-6h, carries out cooling process after constant temperature, rate of temperature fall is cooling 6-8 degree Celsius of every 30mim, is down to normal temperature.
The pre-heating drying of the present invention can make the free water in adobe slough gradually, and base substrate particle tightens each other to be drawn close, and can eliminate or reduce moisture and sharply evaporate the thermal expansion destruction caused. Suffer that premised on steam destruction, the heating-up time should shorten as far as possible, generally sends into steam 1.0-1.5h in curing room to ensure that adobe is unlikely. The main phase that constant temperature is base substrate generation aquation and Hydrothermal Synthesis and intensity is increased. Along with the prolongation of constant temperature time. Hydrated product gets more and more, and the increase of intensity is also more and more faster but after certain time, intensity increase tends towards stability, in general, under 95-100 degrees celsius, spring, autumn constant temperature time be 8h, summer is 7h, and winter is 10h. Cooling strictly to be controlled cooling rate, and the cooling of every 30mim is no more than 10 degrees Celsius, and the temperature head inside and outside curing room is not more than 30 degrees Celsius. Can not arbitrarily open curing room door, take fast cooling, otherwise will cause producing temperature stress between in brick body surface, make surface tension, produce tiny crack.
The present invention is preferred, and building waste pre-treatment is specially: first remove the foreign material in building waste by collecting the building waste obtained; Then coarse breaking is carried out, by the irony thing in the building waste after magnetic separation removal coarse breaking, building waste after removal irony thing is carried out thin broken broken, by magnetic separation remove thin broken broken after building waste in irony thing, the lightweight thing in building waste is removed afterwards by selection by winnowing, the building waste of removal irony thing and lightweight thing carries out being crushed to particle diameter and is less than or equal to 10mm, obtains pretreated building waste.
The present invention is preferred, and the pre-treatment of described cinder is specially: the irony thing being removed cinder by magnetic separation, is carried out being crushed to particle diameter and be less than or equal to 10mm, obtain pretreated cinder.
The present invention is preferred, and the particle diameter of pretreated building waste, cinder, phosphogypsum is for being less than 10mm.
The present invention is preferred, and in step (3), vibrational frequency is 4000-5000Hz, time of vibration 3-4S, and system pressure is 10-15Mpa.
The effect that the present invention reaches and advantage are as follows:
(1) the present invention is by raw material rational allocation and maintenance, define high strength, freeze-thaw-, low cost environmental protection non-burning brick, after raw material mixing match, abundant aquation forms silicon, aluminium profiles vitreum, calcium oxide chemical combination after this kind of vitreum and aquation, produce chemical reaction, aquation silicon (aluminium) acid calcium in chemical reaction is a kind of glue shape vitreum, continuity reaction in time, solidify gradually, form the network structure of a kind of high strength, by the aggregates such as the fragment of brick tile fragment in the building waste after fragmentation linking together tightly.
(2) preparation method of the present invention is under the vibrations and pressure dual effect of machinery, produces the pressure-proof and snap-resistent intensity height of all size, and weight ratio identical size like product is light, the brick body of hot-resistant heat-preserving. Meet building house owed by a citizen, the bearing wall of building and the demand of high-rise frame building body filling simultaneously, it is easy, easy to use, the purposes environmental protection novel wall material widely of a kind of production.
(3) the present invention utilizes industrial waste and building waste to produce, and raw material is extensively cheap, can direct piling; taking up an area few, the cycle is short, and without any pollutant emission in whole making processes; once popularization, play active effect by the water and soil resources protection in the whole world and living environment being improved.
