Shown is a method for producing a granulate for later production of a second aqueous suspension for use as an antifreeze, the method comprising the following steps: heating distilled water to about 50 ° C., adding starch, a pseudoplastic suspension agent, at least one hydrocarbon , in particular a paraffin or an olefin or a mixture thereof, and at least one basic material with constant stirring, heating a first aqueous suspension thus obtained to up to about 90 ° C. for at least 30 minutes, drying the first aqueous suspension, preferably by means of Fluidized bed spray granulation until a dry granulate is formed. In addition, a granulate produced with the aid of such a method is shown, which is used in a further method for producing a second aqueous suspension for use as an antifreeze agent. |
