Description
Technical field
The present invention relates to technical field of concrete additives, specifically a kind of aluminate modified high-efficient liquid accelerator.
Background technology
Accelerator be mix concrete in concrete is condensed the additive of hardening rapidly, with reach repairing or roadway in mix
The purpose of solidifying soil rapid condensation, is indispensable additive in construction of shotcrete engineering method, and the effect of accelerator is to accelerate
The hydration and hardening of cement, forms enough intensity in a short period of time, to ensure special construction requirement；Use in the prior art
Perhafnate:Carbonate=5:0.5 weight than preparation raw material, using aluminium hydroxide:NaOH=1:1.2 weight ratio is matched somebody with somebody
Dispensing processed, its specific preparation method is：The NaOH and aluminium hydroxide of formula ratio are stirred into a few hours under the high temperature conditions, after
Carbonate aluminate is added to continue to obtain accelerator product after reacting 1 hour, its preparation technology needs specified conditions, and prepares week
Phase is long, and the accelerator that production is obtained does not adapt to construction process requirement, so as to the engineering of concrete in work progress cannot be ensured
Quality；And because preparation time is long, precipitate many, it is necessary to carry out under the high temperature conditions, and energy consumption and cost of manufacture are increased, compel to be essential
Carry out technological improvement and improvement.
The content of the invention
Low it is an object of the invention to provide a kind of alkalinity, without sodium ion corrosion, the aluminate of non-stimulated smell is modified
Efficient liquid accelerator, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of aluminate modified high-efficient liquid accelerator, by aluminate solution and modification liquid with 24:1 weight is than preparation
Into the mass fraction of aluminate is 30% in aluminate solution, and in modification liquid, the mass fraction of silicate is 20%, Organic Alcohol
The mass fraction of class is 0.8%.
As further scheme of the invention：The preparation method of the aluminate modified high-efficient liquid accelerator includes following
Step：
1) aluminate of formula ratio is weighed, is inserted to be added water in reactor and is stirred, it is 30% to be configured to mass fraction
Aluminate solution；
2) silicate, organic alcohols are hybridly prepared into modification liquid, in terms of mass fraction, silicate content is 20%, is had
Machine alcohol content is 0.8%；
3) in step 1) reactor in be added dropwise step 2) prepare modification liquid, aluminate solution and modification liquid in reactor
Mass ratio be 24:1,30min is stirred after adding modification liquid, obtain finished product aluminate modified high-efficient liquid accelerator..
As further scheme of the invention：The step 3) in, stir speed (S.S.) is 60r/min, reaction temperature control
At 90 DEG C.
Compared with prior art, the beneficial effects of the invention are as follows：Accelerator alkalinity of the invention is low, rotten without sodium ion
Erosion, non-stimulated smell；Without being carried out under hot conditions again when it is prepared, degraded production cost significantly, reduces energy consumption, energy-conservation
Environmental protection；Caking property is good, and springback capacity is low, and later strength storage rate is high, impervious rank is high, ensure that the raising of construction quality, it is ensured that
Late strength of concrete；Concrete can be made rapidly to condense in a short time, the change to microstructure of concrete is little, is adapted to spray
The special engineerings such as construction technology and repairing, sealing leak stopping are penetrated, market application foreground is wide.
Specific embodiment

The mass fraction of class is 0.8%, and the preparation method of the aluminate modified high-efficient liquid accelerator is comprised the following steps：
1) aluminate of formula ratio is weighed, is inserted to be added water in reactor and is stirred, it is 30% to be configured to mass fraction
Aluminate solution；
2) silicate, organic alcohols are hybridly prepared into modification liquid, in terms of mass fraction, silicate content is 20%, is had
Machine alcohol content is 0.8%；
3) in step 1) reactor in be added dropwise step 2) prepare modification liquid, aluminate solution and modification liquid in reactor
Mass ratio be 24:1, reaction temperature is controlled at 90 DEG C, with the stir speed (S.S.) 30min of 60r/min after addition modification liquid, is obtained into
Product aluminate modified high-efficient liquid accelerator..
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from
Make a variety of changes.
