Description

The present invention relates to a de-icing and anti-freeze composition designed to dissolve an ice sheet over a period of time of several hours.

Easily soluble salts such as sodium chloride, calcium chloride, magnesium chloride are used for winter maintenance of communication routes, of which sodium chloride is most often used due to the speed of ice dissolution. However, due to the relatively high temperature at which sodium chloride optimally dissolves the ice, as the dissolution process is inhibited even below -10 ° C, mixtures of sodium chloride (NaCl), calcium chloride (CaCl2) and chloride are often used to remove black ice and slippery roads. magnesium (MgCl2).

Calcium chloride is a salt that is easily dissolved and strongly absorbs water. Magnesium chloride also strongly absorbs water, dissolves well in water, has good ice solubility, even at temperatures below -25 ° C.

In order to increase the roughness of the surface of roads and pavements, mineral material such as sand or gravel is added to the salt mixtures, but this causes damage to the permeability of the storm sewage system and the outflow of meltwater and rainwater in the spring.

It is also known to use, for de-icing roads, organic materials such as waste products from cheese, wine and grain wet milling.

The de-icing and anti-freeze composition containing an organic material according to the invention is characterized in that it consists of an organic absorbent and readily soluble salts.

The organic material is a coarse fraction of comminuted coconuts, preferably 12 mm to 20 mm in diameter, preferably 18 mm in diameter, present in the composition in an amount of 20 wt.%. up to 40 wt.%, preferably 30 wt.%.

Easily soluble salts are sodium chloride in an amount of 30 wt.%. % to 80 wt.%, preferably 70 wt.%, or a mixture of sodium chloride in an amount of 40 wt.%. % up to 60 wt.%, preferably 50 wt.%. and calcium chloride in an amount from 10 wt.%. % to 30 wt.%, preferably 20 wt.%, or a mixture of sodium chloride in an amount of 40 wt.%. % up to 60 wt.%, preferably 50 wt.%. and magnesium chloride in an amount from 10 wt.%. % to 30 wt.%, preferably 20 wt.%, or a mixture of sodium chloride in an amount of 40 wt.%. % to 60 wt.%, preferably 50 wt.%, of calcium chloride in an amount of 5 wt.%. % up to 15 wt.%, preferably 10 wt.%. of magnesium chloride in an amount of 5 wt.%, 15 wt.%, preferably 10 wt.%, or a mixture of calcium chloride in an amount of 30 wt.%. % to 50 wt.%, preferably 40 wt.%, and magnesium chloride in an amount of 20 wt.%. % up to 40 wt.%, preferably 30 wt.%.

The use of a coarse coconut fraction in the composition according to the invention is justified by a number of properties, such as the unique physical structure of the coconut lignin, which exhibits a very high capacity for salt bioaccumulation and slow degradation at the same time. These features extend the time of the composite's operation, thus reducing the amount of pure salts introduced into the environment. The pH of the organic material used is close to the neutral pH of 5.6 - 6.4, which is important for plant vegetation and changes in the ionic balance in the sorption complex of roadside soils. This material is free from contaminants, pathogens, seeds, pesticides that can directly affect the health of roadside vegetation.

The deicing and antifreeze compositions of the present invention are illustrated in the following examples.

P r z k ł a d 1 coconuts shredded to a diameter of 18 mm - 30 wt.% sodium chloride (NaCl2) the components of the composition must be mixed P r z k ł a d 2 - 70 wt.% coconuts shredded to a diameter of 12 mm - 40 wt.% sodium chloride (NaCl) - 40 wt.% magnesium chloride (MgCl2) - 10 wt.% calcium chloride (CaCl2) the components of the composition must be mixed - 10 wt.%
