Abstract
The invention discloses a kind of foaming agent for being used to mix stone flour foam concrete and preparation method thereof, described foaming agent includes foaming agent mother liquor, can also include foam additive, curing agent, foam stabilizer and water.The foaming agent preparation technology that the present invention announces is simple, and raw material can be purchased extensively.Compared to existing foaming agent, foaming agent of the present invention, which provides, a kind of mixes after stone flour that caused foam concrete homogeneity is poor, the solution method of collapse-deformation and problems of crack.
Description
Technical field
The invention belongs to building material field, and in particular to a kind of foaming agent and its system for being used to mix stone flour foam concrete
Preparation Method.
Background technology
Foam concrete is a kind of construction material of light multifunction, its sound insulation and noise reduction having, insulating refractory, manufacture
The features such as cost is cheap, moulding process is various, it is widely used in heat-insulated building roof, building exterior wall heat preserving, light partition wall, highway
The building fields such as bridge foundation bed course.In general, foam concrete be mainly foaming agent mechanically or compressed air
After foaming, with cement slurry or cement with other mineral admixtures (such as：Flyash, slag etc.) formed composite slurry, enter
After one step is well mixed, shaping hardening forms a kind of functional material.
At present, the admixture applied to foam concrete mainly includes flyash, slag, silicon ash etc..Wherein, flyash
Research it is more, using comparative maturity, be related to application of the agstone in foam concrete and the property to foam concrete
The exploration that can be influenceed is there is not yet compare full report.
Stone flour is processing enterprise of building stones caused byproduct in process of production, and its major traits is that ultrafine solids powdery gives up
Material, essential mineral composition are lime stone, hydrotalcite etc..For a long time, because stone flour economic value added is relatively low, often looked forward to by production
Industry is discarded, and causes the waste of resource and the pollution of environment.In recent years since, raw material that stone flour is produced as foam concrete,
Part substitutes cement, the binder materials such as flyash is proven with feasibility and potential age deduction.
Found through experiment, can stone flour, which be applied to foam concrete, mainly there are two aspect influence factors：On the one hand, stone flour is made
For superfine powder, certain hydrophobicity is shown, after being mixed with foamed solution, causes the performance of foaming agent to reduce or fail；
On the other hand, stone flour meeting part dissolution calcium, magnesium ion after water is contacted, causes the hardness of the aqueous solution to raise, causes foam duration
Time reduces, lather collapse, and initiation mixes that stone flour foam concrete homogeneity is poor, be more easy to collapse, difficult forming and cracking etc. one
Series of problems, limit application of the stone flour in foam concrete field.
Foaming agent is a kind of organic surface active agent, is an important factor for influenceing foam concrete quality.According to raw material come
Source, it is broadly divided into the kind such as rosin soap, synthetic surfactant class, protein-based and complex class.Organic surface active agent by
To influence of both hydrophilic functional group and lipophilic functional groups, different performances is shown.
Rosin soap and partially synthetic surfactant-based foaming agent, hydrophilic radical are generally sulfonate, also referred to as sulfonic acid
Salt form surfactant.Experimental research find that sulfonate surfactant, when running into hard water or calcium, magnesium ion solution,
Produce precipitation, cause foaming capacity to decline, foam through when bleeding increase, foam homogeneity and bad stability.Such as：Chinese patent
CN201410303336.5《A kind of rosin foaming agent》, its main technique is that sulfonic acid group is introduced into rosin native compound
In molecular structure, to improve the hydrophilicity of native compound molecule；Chinese patent CN201310511515.3《A kind of lignin
Base foam concrete foamer and preparation method and application》, its main technique is also that natural lignin is carried out into sulfonating reaction,
To obtain enough frothing capacities.But be on the one hand that foamability is poor in above-mentioned foaming agent, it is vulnerable to other surfaces activity
The influence of material；On the other hand, with calcium, magnesium ion in solution precipitation reaction can occur for sulfonic acid group therein, cause to foam
Agent hydraulic performance decline or failure.
Synthesis nonionic surfactant frothing capacity is poor, and bubble diameter is excessive, and foam wall is thin, and bubbling, it is bad to stablize,
Extensive approval is arrived.Such as：Chinese patent CN201410379164.X《A kind of early-strength composite foam concrete foaming agent and its
Preparation method》With Chinese patent CN201310292824.6《A kind of composite water cement foaming agent and preparation method thereof》Refer to conjunction
Into subject matter existing for nonionic surfactant.
Protide foaming agent adaptability is extensive, foaming performance stable, and synthesis technique is complicated, but price is higher, causes always
Fail to be widely popularized use at home.In recent years since, above-mentioned foaming agent has been subjected to compound and caused complex class foaming agent, although
The problem of compensate for existing using above-mentioned foaming agent, certain effect is have received, but the type foaming agent quality is uneven, shadow
The popularization of foam concrete technology is rung.It is pointed out that complex class foaming agent is using sulfonate surfactant more
Foaming component, foaming aidses component.Such as：Chinese patent CN201410379164.X《A kind of early-strength composite foam concrete foaming
Agent and preparation method thereof》, it is easily hard by water quality comprising sodium cetanesulfonate, dodecyl sodium sulfate etc. in its composite foam agent
Spend the foaming component influenceed；Chinese patent CN201510714903.0《A kind of concrete foamer》And Chinese patent
CN201410701061.0《A kind of concrete foamer of stabilization》Used sodium cetanesulfonate, dodecyl sodium sulfate,
AEO ether sodium sulfate etc. synthesizes non-ionic surfactant component.Because sulfonic acid group is to calcium, magnesium ion
Sensitiveness, cause in actual use, foaming effect of the complex class foaming agent in hard water and high-concentration Ca, magnesium ion class solution and
Foam stability energy is also unsatisfactory.
Therefore need to provide and a kind of be used to mix foaming agent of stone flour foam concrete and preparation method thereof to solve above-mentioned ask
Topic, influence of the incorporation stone flour to foam concrete performance is reduced, promotes promoting the use of for powder discarded object.
The content of the invention
