Description

A kind of preparation method of steam-pressing aero-concrete
Technical field
The invention discloses a kind of preparation methods of steam-pressing aero-concrete, belong to construction material preparing technical field.
Background technology
Autoclave aerated concrete building block is with flyash, lime, cement, gypsum, and slag etc. is primary raw material, is added appropriate Foaming agent, conditioning agent, bubble stabilizer are stirred through dispensing, cast, quiet to stop, cutting and the technical process such as high-pressure steaming and cultivating and be made A kind of celluar concrete product.The bulk density of autoclave aerated concrete building block is the one third of clay brick, heat preservation Performance is 3~4 times of clay brick, and sound insulation value is 2 times of clay brick, and anti-permeability performance is one times of clay brick or more, fire resistance Can be 6~8 times of armored concrete.The masonry strength of building block is about the 80% of building block self-strength(Common brick is 30%).Steam pressure adds The construction property of gas concrete segment is also very excellent, it can not only produce various specifications in factory, can also be as wood Material is equally sawed, is dug, is bored, is followed closely, and since its volume is bigger, and speed of application is also more quick, can be used as general The packing material of building.However, air-entrained concrete building block cubic deformation coefficient is bigger than normal, low strength, water absorption rate are big, and build by laying bricks or stones into When wall, easily there is crack in wall, and coat of plaster is also easy to produce large area cracking, hollowing and obscission, shows apparent brittleness, The further application and popularization of autoclave aerated concrete building block are hindered to a certain extent.In addition to this, with steam pressurized Concrete voids increase, product more lightweight, more convenient to use quick in transport and architectural process, but with its sky The increase of gap will certainly lead to the decline of its mechanical strength, this generates mechanical property and it is Lightness cannot be firm, meet not Quality requirement of the market to steam-pressing aero-concrete, product evaluation are had a greatly reduced quality, and pushing away for steam-pressing aero-concrete is seriously affected Extensively with application.
Therefore, how to improve traditional steam-pressing aero-concrete mechanical property with it is Lightness cannot take into account the shortcomings that, to obtain The steam-pressing aero-concrete for taking more high combination property is that it is promoted and applies, meets industrial production demand urgent problem to be solved.
Invention content
The present invention solves the technical problem of:For traditional steam-pressing aero-concrete mechanical property with it is Lightness cannot Take into account the shortcomings that, provide a kind of preparation method of steam-pressing aero-concrete.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
(1)It counts in parts by weight, takes 8~10 parts successively(N- amidino groups)Dodecylacrylamide, 6~8 parts of polyethylene glycol derive Object, 3~20 parts of calcium bicarbonates, 10~20 parts of carbomers, 70~80 parts of cement, 80~100 parts of white limes, 18~20 parts of gypsum, 300~400 parts of sand, 0.8~1.2 portion of foam stabilizer, 180~200 parts of water first will(N- amidino groups)Dodecylacrylamide and poly- second Diol, derivatives are added to the water, and after being stirred to react 60~90min, add calcium bicarbonate and carbomer, heating stirring reaction 45 After~60min, cement, white lime, gypsum, sand and foam stabilizer are sequentially added, continues to be stirred 2~4h, obtains mixed mortar;
(2)By mixed mortar inject mold in, precuring is quiet stop 2~4h after, demoulding, obtain coagulation sun-dried mud brick;
(3)Coagulation sun-dried mud brick is placed in carbonization case, still kettle is transferred to after the 2~4h that is carbonized, heat-insulation pressure keeping conserves 12~16h, then passes through Natural curing 3~28 days is to get steam-pressing aero-concrete.
Step(1)The polyethyleneglycol derivative is polyethylene glycol-proline derivative or polyethylene glycol-phospholipids derivative In any one.
Step(1)The carbomer is carbomer 910, any one in carbomer 934 or Acritamer 940.
Step(1)The cement is portland cement, aluminate cement, sulphate aluminium cement, fluoroaluminate cement or iron Any one in aluminate cement.
Step(1)The sand is any one in river sand or sea sand;The sand apparent density is 2550~2600kg/ m3, loose bulk density is 1400~1450kg/m3
Step(1)The foam stabilizer is dodecyldimethylamine oxide, polyacrylamide, polyvinyl alcohol, starch or carboxylic Any one in methylcellulose.
The beneficial effects of the invention are as follows:
(1)Technical solution of the present invention is by adding carbomer and calcium bicarbonate, in preparing Concrete, carbomer molecule knot The calcium carbonate crystal that the adsorbable calcium bicarbonate of abundant carboxyl generates after decomposing in structure, and once have nucleus generation that can be inhaled It is attached, avoid further growing up and reuniting for calcium carbonate crystal, in one layer of size of carbomer adsorption in nano level carbon Sour calcium crystal, in subsequent preparation process, the carboxyl in carbomer molecular structure be neutralized in concrete alkaline system and from Sonization, the identical negative electrical charge of carboxylase gene band after ionization and it is mutually exclusive, to make the nano-calcium carbonate particles of absorption in coagulation Fine dispersion in soil body system, to effectively improve the mechanical property of concrete;
(2)Technical solution of the present invention passes through addition(N- amidino groups)Dodecylacrylamide and polyethyleneglycol derivative, utilize two The block copolymer that generates is used as air entraining agent after person's reaction, in molecular structure, polyethylene glycol segment with good hydrophily, And(N- amidino groups)Dodecylacrylamide segment has good hydrophobicity, and such block copolymer is in concrete system Balloon-shaped structure can be spontaneously formed, makes air with micro-bubble formal distribution in concrete structure, and in preparation process, with Calcium bicarbonate decomposes the carbon dioxide gas generated and can interact with the amidine group in block copolymer first, makes block Charge on amidine group band on copolymer side chain, because like charges are mutually exclusive to make balloon-shaped structure volume increase, further The pore structure of abundant product, playing reduces product unit weight, realizes lightening effect.
