Description
Technical field
The present invention relates to a kind of novel super insulation, high-strength manufacturing method of aerated concrete, belong to the Materials Science and Engineering science and technology field.
Background technology
Resource, the energy, environment, economy and performance are the particularly problems that should take all factors into consideration of building material industry development of Materials science.The mankind face the day by day exhausted threat of natural resources day by day, and consuming excessively and the discarded problems such as very serious ecosystem destruction and environmental pollution that caused natural resources.How to protect the limited natural resource, the protection existent environment of people is had direct contact.
According to the relevant regulations of present country, have only use gas concrete, just can accomplish the requirement of single inorganic materials energy-conservation 50%～80%.And other any inorganic materials will accomplish energy-conservation 50%, must carry out Combined Processing, as materials such as load bearing hollow bricks, all need and the compound solution power saving of lagging materials such as polystyrene, hard polyurethane foam, and the long construction period of combined wall, technology are complicated, cost is high, and need to add organic materialss such as synthetic resins, therefore also have shortcomings such as inflammable, that combustion processes waste gas toxicity is big.
The production method of gas concrete is: with cement, quartz sand and calcium lime powder as main raw material, mix acquisition foam slip with gypsum, aluminium powder, water and bubble stabilizer etc., then the foam slip casting is gone in the mould, adopt steaming pressure equipment to carry out autoclave curing and obtain goods.Because the gas concrete after the sclerosis comprises a large amount of vigorous mullites of high crystalline holder, thereby has weather resistance and fire resistance preferably.Current, comparatively sophisticated industrialization gas concrete product, its over dry density is many at 400～700kg/m
3Between, thermal conductivity is about 0.09～0.15W/ (mK), can't satisfy energy-conservation about 80% the technical requirements of single-material.And density is 300kg/m
3Powder ash air-entrained concrete building block ultimate compression strength then be low to moderate 1.0MPa, still be apparent not enough as the packing material intensity of concrete frame structure building, and labour productivity is low.The performance boost technology of tradition gas concrete adopts fiber, non-crystalline state SiO more
2, synthetic resins carries out the enhancing of material and the improvement of thermal property, unavoidably brings stable on heating decline, and keeps under the condition of certain ultimate compression strength, it is limited that thermal property is improved amplitude.

For lubricated tackifier,, do not possess the thixotroping lubrication when its massfraction during less than 0.005 part; And when greater than 1 part, the super heat preservation property of goods is difficult to realize.
Require the foam slip when being poured into mould, its diffusibleness should be controlled between 16～30cm, and when being poured into behind the mould 15 minutes, the diffusibleness of foam slip should be controlled between 10～22cm.15 minutes higher limit after foam slip diffusibleness surpasses mould and goes into mould, then the bubble longitudinal uniformity variation of goods; 15 minutes lower value after foam slip diffusibleness is lower than mould and goes into mould then is difficult to obtain the super heat preservation property of patent goods of the present invention.After being poured into mould, depressing by the autoclave maintenance at the saturation steam of 1.1～1.6MPa and can make novel gas concrete of the present invention.When temperature was lower than 150 ℃, it was slack-off to ask vigorous Study on Mullite Gel to produce; When temperature was higher than 200 ℃, part ask vigorous Study on Mullite Gel to change hard afwillite into, caused product strength to descend.
Beneficial effect: (1) goods of the present invention have characteristics such as lightweight, high-strength, difficult combustion, insulation, heat insulation, hydrophobic, long service life, shock resistance, contraction be little.(2) the goods height of gas concrete of the present invention can be higher than the height of indoor standard specimen, more is applicable to suitability for industrialized production than high-strength light gas concrete of the prior art.Easy to prepare, production efficiency is high; And only needing to increase on the basis of traditional gas concrete shop equipment a slip prepares the pond and can produce.(3) material modified composition of the present invention is simple, and material source is extensive.(4) more traditional product strength performance and the thermal property of aerated concrete products of the present invention has a greater degree of improvement, ultimate compression strength is 1.2～5.0MPa, thermal conductivity is 0.056～0.09W/ (mK), its outstanding feature is exactly the characteristic with super insulation, and over dry density can be low to moderate 200～450kg/m
3, going out the still water-intake rate below 20%, the still water-intake rate (being about about 30%) that goes out of industrialization product has very big decline at present, and more existing gas concrete has more excellent intensity, satisfies the demand of current country to energy-saving and emission-reduction.(5) gas concrete of the present invention has workabilitys such as cutting, grinding, and available suitable matrix material bonding, for condition has been created in building operation.
