Abstract
The invention discloses an improved preparation method of a heatproof baking-free brick. The preparation method comprises the following steps: step one, grinding sintering ash of power plants into blocks with a particle size of 10 mm; step two, mixing 35 parts by weight of sintering ash blocks with a particle size of 10 mm with 25 parts by weight of coal slag powder, 25 parts by weight of common sand, 8 parts by weight of cement, 7 parts by weight of calcium oxide with a particle size of 15 mm, 5 parts by weight of calcium silicate, 1.5 parts by weight of sodium sulfate, 1 part by weight of sodium silicate, 5 parts by weight of water soluble unsaturated resin, and 2 parts by weight of silicon powder, adding the mixture into 15 parts by weight of water, mixing, and stirring to obtain a wet material; step three, pressing the wet material into moulded baking-free bricks under a pressure of 25 MPa by a baking-free brick moulding machine; step four, naturally maintaining the baking-free bricks at a room temperature for four weeks through a water spraying method. Compared with the prior art, sintering ash of power plants is taken as the main raw material, the environment is protected, and the prepared baking-free brick has the advantages of high strength, high heat resistance temperature, strong thermal insulation property, little capacity, high specific strength, and good durability.
Description
Technical field
The present invention is Patent No. 201310014176.8, filing date on 01 15th, 2013, the divisional application of the patent of invention of entitled " a kind of non-burning brick formula and preparation method thereof ", relates to a kind of non-burning brick, is specifically related to a kind of heat-resisting non-burning brick improvement preparation method.
Background technology
China is that brick body consumes big country, also it is the big producing country of brick body, common brick is traditional materials for wall, mainly with being raw material with arable land lower floor clay, after being built into cuboid adobe, in brickkiln, open fire calcination forms, this brick is the most frequently used construction material in current city and rural area, in order to protect the arable land day by day reduced, country has prohibited the production of clay brick, past, the most once trial cement brick replaced clay brick, but the production of cement brick and use cost are higher, there is also simultaneously and self estimate one's own ability greatly, it is not suitable with the defect that skyscraper uses, recent year exploitation is a kind of non-burning brick, it is compressing after mainly using flyash and cement mixing, it is high to there is cost in non-burning brick compressing with cement mixing of this employing flyash, intensity is low, poor durability, heat resisting temperature is low, anti-freezing property is bad, the defect of brick body weight.
China is the country based on combustion power generation, substantial amounts of waste incineration residue can be discharged every year due to combustion power generation, i.e. refuse-burning plant sintering ash, this garbage power calcium oxide causes serious pollution and harm, and containing the useful component such as part ferrum and calcium oxide in refuse-burning plant sintering ash, if able to recycle, a lot of valuable resource will be saved.
In view of this, drawbacks described above is furtherd investigate by the present inventor, is then produced by this case.
Summary of the invention
The present invention proposes a kind of heat-resisting non-burning brick improvement preparation method, which solves power plant sintering ash processing cost high, the problem being unfavorable for environmental protection, utilize power plant sintering ash containing the brickmaking utility such as a small amount of iron powder and calcium oxide simultaneously, improve the intensity of brick, bridging property and adhesive so that the non-burning brick comprcssive strength made reaches 18.1Mpa, heat resisting temperature is 1013 DEG C, there is intensity high, heat resisting temperature is high, and thermal insulation is strong, and unit weight is little, specific strength is high, the advantage of good endurance.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions: a kind of heat-resisting non-burning brick improvement preparation method, comprises the following steps:
One, sintering ash in power plant is pulverized: power plant sintering ash is crushed to the block that particle diameter is 10mm；
Two, dispensing stirring: be 35 parts and power plant that block is 10mm sintering ash and the cinder powder that weight portion is 25 parts by weight portion, weight portion is the normal sands of 25 parts, weight portion is the cement of 8 parts, weight portion is 7 parts and particle diameter is the calcium oxide of 15mm, weight portion is the calcium silicates of 5 parts, weight portion is the sodium sulfate of 1.5 parts, weight portion is the sodium silicate of 1 part, and weight portion is the water solublity unsaturated-resin of 5 parts and Testudinis powder that weight portion is 2 parts adds the water that weight portion is 15 parts and is mixed into the material of moist shape；
Three, compressing: to use Non-fired brick moulding machine by compressing non-burning brick for the material of above-mentioned moist shape under the pressure of 25MPa；
Four, maintenance: by the spraying surrounding of natural drying maintenance at normal temperatures.
By using preceding solution, the invention has the beneficial effects as follows: it uses power plant sintering ash to be primary raw material, and not only twice laid eliminates the sintering flying dust pollution to environment, beneficially environmental protection；And containing the brickmaking utility such as a small amount of iron powder and calcium oxide in power plant sintering flying dust, iron powder is favorably improved the intensity of brick, and the sintering time of 6～8 hours can be shortened, calcium oxide can improve bridging property and the adhesive of brick, reduce the weight part ratio of non-burning brick required calcium oxide, reduce material cost；Adding water solublity insatiable hunger water fat in formula, water solublity unsaturated-resin further increases bridging property and the adhesive of brick, effectively reduces the consumption of calcium oxide, reduce further cost, improve intensity；Adding calcium silicates in formula to be modified it, make the comprcssive strength of the product of gained reach 18.1Mpa, heat resisting temperature is 1013 DEG C, has heat resisting temperature high, and thermal insulation is strong, and unit weight is little, and specific strength is high, good endurance.
