As preferably, the described fluoride in formula is the combination in sodium fluoride, Zinc fluosilicate, Calcium fluosilicate.
In the present invention, the preparation method of anti-freeze type alkali-free chlorine-free liquid accelerator is: first add in reactor by cold water, so
Fluoride in rear addition formula, adds the magnesium in formula and sodium rhodanate, starts to warm up, in the process heated up after stirring and dissolving
In be initially added into aluminum, when the temperature in reactor more than 60 DEG C time make aluminum be completely dissolved, be subsequently adding ferrum in formula, by reactor
Cooling, adds anticorrosion preservative when temperature is brought down below 40 DEG C so that it is after melting completely, stirring 10 minutes is finished product.
Wherein aluminum sulfate must dissolve more than 60 DEG C, and otherwise freeze-proof is very poor, and anticorrosion preservative must be in cooling
After could add.
Beneficial effects of the present invention: anti-freeze type alkali-free chlorine-free liquid accelerator has and do not crystallizes, without freezing block, less than-20
After DEG C enduring cold, product dissolves the advantages such as not inefficacy.And its production technology is simple, can make at ambient temperature-20 DEG C 40 DEG C
With, and this product anti-freezing type is good it can also be used to wall effect in hot environment, and its low cost, alkali-free chlorine-free environmental protection, injection
Good, concrete springback is little, early strength and later strength is high, long shelf-life.
