Abstract
The present invention discloses an anti-freezing ceramsite reinforced aerated block, which is characterized in that the anti-freezing ceramsite reinforced aerated block is prepared from the following raw materials by weight: 7-9 parts of nylon fibers, 30-50 parts of ceramsite, 15-30 parts of fly ash, 10-15 parts of quick lime, 14-18 parts of cement, 0.3-0.6 part of aluminum powder, 2-4 parts of phosphogypsum powder, 3-4 parts of a polyurethane emulsion, 0.3-0.5 part of calcium lignosulfonate, 1-3 parts of iron powder, 3-5 parts of nanometer aluminum oxide, 2-4 parts of, 15-20 parts of, and a proper amount of water. According to the present invention, with the used process method, the problems that the ceramsite is easily broken during the processing process and the distribution is non-uniform in the slurry due to the light weight are solved; the added nylon fibers have effects of improvement of the cracking and tensile strength of the aerated block plastering layer, improvement of the freeze-thaw resistance of the aerated block, and prevention of cracking; and the aerated block production process is simple, the production cost is low, and the product has advantages of light weight, energy saving, thermal insulation, freezing resistance and the like.
Description
Technical field
The present invention relates to aerated-block field, is specifically a kind of antifreeze ceramicite-reinforced aerated block.
Background technology
The building material many employings clay brick used in building construction before China; but recent years; for the protection to soil, reduce the usage quantity of clay brick gradually, some areas prohibit the use the policy of clay brick to release and in commission.Therefore, the building material finding a kind of instead of clay vitrified brick has become the cardinal task in building trade.The a series of building materials such as Dinas brickes, hollow masonry, cement brick all have and are used under construction.Air-entrained concrete building block also along with the visual field entering people, and relies on the feature of itself to become new lover in building trade gradually.Air-entrained concrete building block has countless small, independent, the air hole structure that is evenly distributed and forms the several functions such as high-strength light, durable insulation, sound-absorbing, waterproof, antidetonation, quick construction (compared with clay brick), workability be strong, is a kind of excellent novel wall material.
The most outstanding advantage of nylon fiber is exactly wear resistance, its hypoelasticity is good, light weight, be added in concrete and can play drawknot and skeleton, cracking resistance and the tensile strength of coat of plaster can be improved, not easily produce crack to come off, and the nylon fiber added significantly improves the freeze-thaw resistance of gas concrete, strengthen the frost resistance of building block.Haydite is a kind of artificial light aggregate, shell is hard, inside has micro-porous ceramic saccharoid, it has good heat insulation property, has excellent fire-resistance, and surface has one deck water proof to protect the glaze layer of gas, water-intake rate is low, impervious shock resistance is good, anti-freezing property and excellent in durability, has excellent physics, chemistry and hydraulic performance.Add in haydite to gas concrete and can reduce concrete unit weight, reduce flooring load, also there is the effects such as heat-insulation and heat-preservation, sound insulating and absorbing, freeze proof impervious, environmental protection, but due to the aglite that haydite is a kind of hollow, in whipping process, because the ratio of slip is great, haydite easily floats, cause skewness, form product defects.
Summary of the invention
The object of this invention is to provide a kind of antifreeze ceramicite-reinforced aerated block and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:

The antifreeze ceramicite-reinforced aerated block of one of the present invention, be made up of following concrete steps:
(1) iron powder, carbon black and nano-aluminium oxide to be added in the dehydrated alcohol containing 0.5% silane resin acceptor kh-550 ultrasonic disperse even, after dry and haydite mix and be added in sintering oven, sinter under 1000-1200 ° of C 1-2 hour for subsequent use;
(2) sintering ceramsite prepared by step (1) is soaked 12-24 hour in pond, then mixing and stirring in water phosphogypsum powder and polyaminoester emulsion being added to 2-3 times of weight part, be heated to 20-25 ° of C, and above-mentioned haydite stirs for subsequent use;
(3) by flyash, cement and unslaked lime mixing and stirring, the water and the calcium lignin sulphonate that add 2-3 times of weight part stir 3-5 minute, the haydite and the nylon fiber that add step (2) again continue to stir 3-4 minute, then stir 20-40 second by adding after appropriate water-dispersion aluminium powder;
(4) product of step (3) is added in cast stirrer to stir and make slurry, slurry is entered mould, mould is put into baking oven and leave standstill the 2-3 hour that gets angry, excision exceeds the part of mould, the demoulding, then be put in still and carry out vapor cure, vapor pressure is 1.1-1.3MPa, temperature is 180-190 ° of C, and the steam-cured time is 8-12 hour.
Advantage of the present invention is: the present invention utilizes carbon black and iron powder reaction to make haydite generate the little and structure that specific surface area is large in inner aperture, increase the contact area with slurry, strengthen cohesiveness, utilize the intensity of alumina modified enhancing haydite and reduce the coefficient of shrinkage, pre-wetted treatment and surface coated processing method is adopted to solve haydite breakable problem in the course of processing, the cohesiveness of further enhancing and sand-cement slurry, prevent from floating in the slurry skewness, the nylon fiber added has the cracking resistance and tensile strength that improve building block coat of plaster, improve the freeze-thaw resistance of aerated-block, prevent cracking, building block manufacture craft of the present invention is simple, cost of manufacture is cheap, product lightweight, energy-conservation, insulation, the advantage such as freeze proof.
