Description
Technical field
The present invention relates to a kind of concrete additive, and in particular to a kind of gunite concrete liquid alkali-free chlorine-free accelerator
And preparation method thereof.
Background technology
In the prior art, gunite concrete is broadly divided into two kinds of aqua and pulvis with accelerator, and wherein aqua includes again
Alkali accelerator and alkali-free quick-coagulant, substantial amounts of sodium ion due to having in alkali accelerator be present and easily occur after alkali-aggregate reaction causes
Phase intensity declines the phenomenon for even ftractureing, coming off；So alkali-free liquid accelerating agent just becomes optimal selection.And current nothing
There is the present situation that production process is cumbersome, production cost is high in alkali liquid accelerating agent, greatly constrain alkali-free liquid accelerating agent in work
Popularization in journey, also rarely have businessman to produce and sell such accelerator.Common alkali-free liquid accelerating agent generally uses work on the market
The polyaluminium sulfate of industry level is as main functional component.
The content of the invention

Divide, concrete enhancing component, pH regulation components.
It is further preferred that above-mentioned gunite concrete, with liquid alkali-free chlorine-free accelerator, the solidifying component of rush is sulfuric acid
Aluminium and/or aluminum fluoride；The stable component is citric acid, urea, triisopropanolamine, glycine, lactic acid, the mixture of sucrose；
Concrete enhancing component is in magnesium sulfate, magnesium fluosilicate, sodium metasilicate, calcium formate, calcium oxalate, calcium nitrate, hydroxylmethyl cellulose
One or more of mixing in element；The pH regulations component is one or more of mixing in phosphoric acid, sulfuric acid, trifluoroacetic acid.
Further, for above-mentioned gunite concrete with liquid alkali-free chlorine-free accelerator, the stable component is citric acid, urine
Element, triisopropanolamine, glycine, lactic acid, sucrose are according to mass ratio (1-6)：(1-6)：(1-6)：(1-6)：(1-6)：(1-6) is mixed
Close and prepare.
Alkali-free chlorine-free liquid accelerating agent preparation technology is comparatively simple, it is thus only necessary to which casings in twice, once heating can be complete
Into all operations, the production enforcement difficulty of enterprise is greatly reduced.Secondly, this accelerator selects the raw material of relative low price,
Have that stability is strong, hydrotropy is good using citric acid, urea as main complexing stable elements while be also that concrete is early strong
Agent, the solubility of aluminum sulfate in the solution can be greatly promoted and be enough to substitute polyaluminium sulfate while improve early strength；Three is different
Propanolamine can postpone the holding time of accelerator as auxiliary stabilizer, while can also improve early stage as concrete early strength agent
Intensity.Magnesium sulfate, sodium metasilicate and the miscible dissolution velocity that can significantly improve aluminum sulfate of aluminum sulfate, are that this technique is so simply closed
Key, make stable system with stablizing component generation complex reaction when aluminum sulfate quickly dissolves.
Further, for above-mentioned gunite concrete with liquid alkali-free chlorine-free accelerator, the solidifying component of rush presses following quality
Proportioning composition：The mass ratio of aluminum sulfate and aluminum fluoride is (1-5)：(1-5).
Further, above-mentioned gunite concrete is with liquid alkali-free chlorine-free accelerator, and the concrete enhancing component is by such as
Lower quality proportioning composition：In magnesium sulfate, magnesium fluosilicate, sodium metasilicate, the matter of calcium formate, calcium oxalate, calcium nitrate, hydroxymethyl cellulose
It is (10-14) to measure ratio：(7-10)：(1-2)：(1-2)：(1-2)：(1-3)：(1-2).
Further, above-mentioned gunite concrete with liquid alkali-free chlorine-free accelerator, by following quality matched somebody with somebody by the pH regulations
Than composition：Phosphoric acid, sulfuric acid, the mass ratio of trifluoroacetic acid are (1-5)：(1-5)：(1-5).
Above-mentioned gunite concrete includes step with the preparation method of liquid alkali-free chlorine-free accelerator：
S1. water is added in a kettle, is kept stirring for, and pre-heating temperature elevation is to 80 DEG C
S2. solidifying component, stable component, concrete enhancing component will load weighted in advance be promoted after temperature reaches design temperature
It is added in reactor, reacts 1.5 hours in the lump；
S3. pH regulations component is added dropwise after reaction terminates to adjust pH value to 2, naturally cools to room temperature and produces product.
The present invention has the advantages that：Alkali-free chlorine-free liquid accelerating agent non-corrosiveness provided by the invention and excitant
Smell, it is in stable condition, adaptability is good.According to JC477-2005 experiment condition, alkali-free chlorine-free liquid rapid hardening provided by the invention
Agent is certified products when parameter is 5-7%.
