Description
Affiliated technical field:
The present invention relates to chemical industry, building material field, is a kind of polymerization foam concrete cement blowing agent and preparation method specifically.
Background technology:
At present kind, the method for preparing foamed concrete with foaming agent, air entrapment agent, cement blowing agent has a lot, but all has a lot of weak points, is summarized as follows:
Foaming agent, air entrapment agent, the cement blowing agent kind of domestic production foamed concrete employing at present; Gum rosin foaming agent, the agent of sodium resinate class A foam A, useless animal wool foaming agent, hydrolysis blood glue foaming agent, oil Tai-Ace S 150 foaming agent, gum rosin and the agent of gelatin mix-froth are a kind of low molecule foaming agent colloidal sol.
Above foamed concrete foaming agent feature and result of use:
The gum rosin foaming agent, the agent of sodium resinate class A foam A, rosin is in acid in the world, the condition of alkali is difficult to make water-soluble solution, what make is a kind of swelling gum rosin that is insoluble in water, most of gum rosin is with the insoluble micella of white, microparticulate is in water, because hydrolyzate is few, tool low foaming, poor stability in concrete, only as concrete air-entrainer, so also claim little foam air entrapment agent, the foam volume that this class air entrapment agent makes is little, is not suitable for to introduce 50%-85% stable foam in concrete, makes lightweight, the pore sealing, the whipping agent of the foamed concrete of equal spoon.
Easy oxidation produced contaminate environment during useless animal wool foaming agent, hydrolysis blood glue foaming agent used.
Some foaming agent, air entrapment agent, whipping agent are that two-pack or polycomponent could be made foamed concrete.
These foaming agents, air entrapment agent, whipping agent can not directly insert makes 1500 kilograms foamed concrete in the concrete.
Be a kind of low molecule foaming agent colloidal sol.When equal conditions used, consumption was big, and the foaming agent frothing percentage is low, sent out foaming agent when consumption 0.5%-3%, 20 times-32 times of foam expansion.
This class is hanged down the calcareous mud of the not anti-height of molecule colloidal sol whipping agent foam, introduces bubble breakage behind the concrete mud, produces bubble effusion, segregation, layering between the foamed concrete mud material initial setting time that makes, flocculates, caves in, depression, contraction, bleeding.
Bleeding rate: send out foaming agent when consumption 0.5%-3%, bleeding quantity 40ml-150ml
The depression distance: send out foaming agent when consumption 1%-3%, depression is apart from 5mm-50mm
The foamed concrete mud that makes can not shake, and the bubble of the foamed concrete mud that is shaken produces and breaks, and bubble converges pressurized and overflows, and is unfavorable for large volume, high level, long distance pumping continuous pouring and conveying.Be unfavorable for suitability for industrialized production foamed concrete.
The foamed concrete mud discontinuity that makes is poured into a mould highly lowly, and cast large volume foamed concrete mud need add extra light perlite, haydite, fiber and other material and improve the anchorage force in mud bubble space.
More than foamed concrete mud initial set 8-15 hour that makes, final set 15-24 hour,
It is hard that the cycle reaches 3 days admittedly.
The foamed concrete admant appearance that makes produces the loose face of irregular efflorescence, crack, integral smoothness is low, and pore is open irregular flat, linear tubulose, produces stiff contraction, resistance to compression, anti-folding, heat conduction, sound insulation physicals reduce significantly, lose the environmental protection and energy saving requirement.
The foamed concrete admant that makes surface produces hydrophobic nature, and water generates is repelled, and the construction that is unfavorable for boning on the admant surface can reduce cohesive force between the object, and the generation paste comes off.
The foamed concrete admant water-intake rate that makes is up to 56%, causes the foamed concrete moisture of attracting deposit, and causes the seepage phenomenon.Be unfavorable for waterproof, the demanding body of wall of sound insulation and thermofin are used.
The foamed concrete complex manufacturing need to add the admixture water-resisting agent, is distributed to, hardening accelerator, anti-fissuring agent, adjusting material, with organism it is showed the dipping polymerization, improves intensity and reduces water-absorbent.
The foamed concrete of system can not use steam curing owing to produce material layering, and the generation of infusion colloidal sol dissolves in the foamed concrete in the higher temperature of steam, causes foamed concrete to produce mutation.
Foaming agent chemical property instability, staging life, is short, and 16 months staging lifes,, chemical property reduced along with the time therebetween.
