The principle of the moulding of gaining in strength of the present invention, for after: the material using and water mixes, produces gas foaming and expands, and produce heat under hydration; Under the effect of closed mould, producing pressure gains in strength.Now, swelling agent starts slowly to expand under heat effect, and its mechanism is again to pressurize to the bulk material of turgor mould, makes bubble more closely knit, and intensity is improved greatly; Cement intensifier wherein can make product improve for the third time intensity in the later stage; Aqueous epoxy resins is a kind of macromolecule crosslink agent, and its molecular structure is tight, and acid-fast alkali-proof is tough and tensile solid after solidifying, and its feature can be solidified at wet environment.Be dispersed in above-mentioned materials, after foaming, formed the very fast curing molding of heat that foam wall produces by foaming, after moisture evaporation, formed tough and tensile solid air bladder, increased resistance to compression, tension, anti-folding, the resistance to impact shock of product.The air bladder forming because of this material is all airtight and is difficult for fragmentation, therefore intercepted the conduction of heat, so can effectively increase thermal resistance, improves heat insulating effect.The intensity of product has improved greatly, can reduce unit weight reaching after requirement, and unit weight has reduced can reduce labour intensity, can reduce the heavy burden of buildings, is also conducive to antidetonation mitigation; The phase transformation masterbatch, the ceramic fine bead that have used high-efficiency insulated lagging material, play function of heat insulation, eliminated cold bridge.
Improve the mechanism of heat insulation effect: phase transformation masterbatch is a kind of high-efficiency thermal storage material, and its mechanism of action is thermal lag transmission; When external temperature too high (higher than design temperature), phase transformation masterbatch starts absorption temperature, makes high temperature transmission less than indoor, by this mechanism, can increase wall heat resistance, improves heat insulating effect; Phase transformation masterbatch is the material after phase change material and carrier composite package, and term source is the provincial standard DB21/T2096--2013 of Liaoning Province.
The block self-thermal insulation material of moulding is closely knit air bladder, each bubble is independently, not connected, thereby intercepted the conduction of heat, it itself is exactly good lagging material, the thermal lag effect of adding phase transformation masterbatch can delay the transmission of temperature and the function of heat insulation of aluminum silicate fiber and nano silicon, has formed a good heat preserving and insulating material.The self heat insulation wall thermal resistance of building by laying bricks or stones with this bulk material is large, exceedes energy-conservation 65% requirement.
Aluminum silicate fiber is a kind of heat preserving and insulating material, thermal conductivity little (0.030 left and right), and quality is light, every cubic metre is less than 80kg, and described nano silicon is a kind of thermal insulation material, and its specific surface area is large, quality is light, and every cubic metre is only 100kg, thermal conductivity little (0.020 left and right); Can effectively reduce unit weight, improve heat insulation effect, and also have waterproof effect.
Hydrophober, hydrophobizing agent can reduce water ratio and the water-intake rate of block insulation material.
Water reducer can reduce water consumption, the raising intensity of moulding.
Setting accelerator can impel bulk material solidifies, shortening forming time, enhances productivity.
Reticulin fiber and aluminum silicate fiber can increase toughness and the splitting resistance of bulk material, and rise and reduce unit weight and insulation effect.
Resin rubber powder plays crosslinked and stabilization, and can increase snappiness.
Ash calcium powder can be gained in strength and be flexible.
Diatomite is vesicular light material, is added in heat insulation anti-crack mortar and spreads upon inner side of outer wall, has sound-absorbing suction and makes an uproar and aldehydes removal germicidal action.
Beneficial effect of the present invention is:
1, greatly improve the intensity of product, at product strength, met the requirements of on basis and reduce unit weight, further reduced labour intensity;
2, reduce the heavy burden of buildings, be also conducive to antidetonation mitigation;
3, shortening forming time, enhances productivity, and effectively reduces unit weight, improves heat insulation effect, and also has waterproof effect.
4, have fire prevention, insulation, the integrated multi-efficiency of wall body structure concurrently.
5, once construction, had both completed building by laying bricks or stones of main body body of wall, had reached again energy-conservation 65% requirement, did not need to do heat preservation construction again, and had solved heat insulation system and the construction wall problem with the life-span.
