Description
Technical field
The invention belongs to the concrete accelerators in building material field, more particularly to a kind of high stable type alkali-free chlorine-free
Liquid accelerating agent and preparation method thereof.
Background technology
It is limited with the development of the infrastructure industry such as China's high ferro, highway and subway, and by China's geomorphic feature
The constructing tunnel of system, central and west regions high ferro and highway is relatively more, therefore the demand of gunite concrete is also to carry year by year
It is high.And concrete accelerator is an essential part in gunite concrete, the quality of effect directly influences injection and mixes
Coagulate the jet quality of soil.The technical merit of gunite concrete is mainly reflected in the research and application of accelerator.Therefore, it closes both at home and abroad
Accelerator is all placed on very important position in the research of concrete spraying additive material.
Gunite concrete is divided into powder accelerator and liquid accelerator with accelerator by state；Liquid accelerator is divided into alkalinity
Liquid accelerator and alkali-free liquid accelerator.Wherein powder accelerator and alkaline liquid accelerating agent that there are operating environment dust is big,
The shortcomings of corrosivity is strong, springback capacity is big, later strength loss is big and durability is poor, and alkali-free liquid accelerator and these are not present
Defect.
The patent document of Publication No. CN102992677A discloses a kind of alkali-free liquid accelerator, and aluminum sulfate is used to make
For rapid hardening component, organic amine and polyalcohol are as stabilizer, but its stable component volume is bigger, are negatively affected to early strength
It is very big, while other stabilization aids are not contained, the stability of the accelerator is also poor.Equally, publication number is respectively
Accelerator disclosed in the patent document of CN104370489A, CN104446090A, CN103664034A, CN103553406A
In, the hydramine substance of 6-10% or so is all added, this can also have early strength larger negative effect.Publication No.
2% or so hydramine substance is only added in accelerator disclosed in the patent document of CN104891852A, but it is not deposited equally
In other stabilization aids, stability is poor.Ammonia is used in accelerator disclosed in the patent document of Publication No. CN103396027A
Accelerating component of the water as alkali-free liquid accelerator, but the use of ammonium hydroxide can have a negative impact to human body.Publication No.
The magnesia that 5-25% is added in accelerator disclosed in the patent document of CN104108894A, since there is no reacting
Substance, therefore can be problematic in terms of its solubility, at the same free magnesium be added after concrete can be generated it is certain stable
Property harmful effect.
To sum up, the stabilization component of alkali-free liquid accelerator is substantially DETA, hydramine or polyalcohols substance at present, but deposits
In following defect：EDTA is quantitative complexing with aluminium ion, if the incorporation of hydramine and polyalcohol is smaller, stabilizing power is complexed
With regard to limited, if addition is more, early strength can be by larger negative effect.Therefore, to solve this drawback, break alkali-free
Conjugate relation in liquid accelerator between early strength and stability researches and develops a kind of network of novel adaptation alkali-free liquid accelerator
It is that current alkali-free liquid accelerator industry pole need to improved target to close stabilising system.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of high stable type alkali-free chlorine-free liquid accelerating agent and its
Preparation method, this method repetition stability is good, pollution-free, is free of formaldehyde, not chloride ion-containing, high stable type alkali-free chlorine-free obtained
Liquid accelerating agent product is non-corrosive, have no irritating odor, cement adaptability is good, volume is low, setting time is short, early intensity
Height, later strength is not lost, stability is very good under conditions of -15~30 DEG C.
The technical solution adopted by the present invention to solve the technical problems is：
Present invention firstly provides a kind of high stable type alkali-free chlorine-free liquid accelerating agents, by the raw material components of following parts by weight
Composition：47-55 parts of rapid hardening component, inorganic accelerating component 3.5-6 parts, 27.9-44.2 parts of deionized water, 1-3 parts of solubility enhancing component, network
It is combined point 2.5-5 parts, 0.2-0.6 parts of thickener component aqueous solution, organic accelerating component 0.6-1 parts, pH adjusts 1-1.5 parts of component.
Preferably, the rapid hardening group is divided into Patent alum.
Preferably, the inorganic accelerating component is one kind in ANN aluminium nitrate nonahydrate, sodium fluoride, magnesium sulfate, ferrous sulfate.
Preferably, the solubility enhancing component is one or both of Tween-20, Tween-80.
Preferably, the complexing components are two kinds in 18- crown-s 6,1-hydroxy ethylidene-1,1-diphosphonic acid, aminotrimethylenephosphonic acid.
Preferably, the thickener component is one kind in polyacrylamide, polyethylene glycol；The polyacrylamide is molecule
Measure 5,000,000-1,000 ten thousand；Molecular weight polyethylene glycol is 4000.
Preferably, the thickener component aqueous solution mass concentration is 5-10%.
Preferably, organic accelerating component be diethanol amine, triethanolamine, one kind in diethanol monoisopropanolamine or
It is several.
Preferably, the pH adjustings group is divided into one kind in 85% phosphoric acid, p-methyl benzenesulfonic acid.
The present invention also provides a kind of preparation methods of above-mentioned high stable type alkali-free chlorine-free liquid accelerating agent, including in order into
