Definitions
- the present invention relates to a method for melting snow and / or ice on traffic areas by applying a deicing agent from an aqueous solution of alkali metal acetate, surfactant and defoamer, as well as this deicing agent.
- salts are used as de-icing agents, the following requirements in particular should be met:
- the salt should damage or not damage or even decompose the material from which the surfaces mentioned are built, for example concrete according to DIN 18500, or even decompose than previous de-icing agents.
- the salt used should cause rapid and as far as possible thawing and / or icing if the precipitation freezes
- alkali metal and alkaline earth metal chlorides as well as alkali metal and alkaline earth metal salts of organic acids, are particularly advantageous deicing agents in the prior art called.
- US Pat. No. 4,855,071 and EP-A-0 579 014 describe alkali metal and / or alkaline earth metal carboxylates having 1 to 4 carbon atoms, prepared by a specific process, as deicing agents, with calcium / magnesium acetate or sodium acetate being particularly recommended becomes.
- EP-A-0483 721 describes a liquid deicing agent which consists essentially of water, an alkali metal and / or alkaline earth metal acetate and special corrosion inhibitors.
- US Pat. No. 5,376,293 also describes mixtures of various alkali metal and alkaline earth metal carboxylates with a carbon chain length of Ci to C 3 .
- Alkaline earth metal carboxylates only insufficiently meet the requirements for a de-icing agent.
- the object of the invention is therefore to develop from the large number of deicing agents in the form of alkali metal and / or alkaline earth metal chlorides and alkali metal and / or alkaline earth metal carboxylates, which has a high effect on lowering the freezing point and in the 5 process of icing by freezing precipitation in the form of snow, rain or freezing fog or thaws offers longer freeze protection times than comparable de-icing agents.
- This liquid deicing agent should also be particularly stable against segregation of the individual components.
- the deicing agent should also be particularly ecological and physiological
- a certain aqueous solution of alkali metal acetate in combination with a surfactant and defoamer and a suitable corrosion inhibitor in small amounts in particular a 10 aqueous solution of the potassium salt of acetic acid and a suitable surfactant and defoamer and corrosion inhibitor in small amounts, all has the required properties when used as a deicing agent.
- the invention therefore relates to a deicing composition containing
- Another object of the invention is a method for melting snow and ice on traffic areas by applying 5 to 100 g / m 2 of the deicing agent according to the invention to the traffic area.
- the amount of deicing agent to be applied depends primarily on the outside temperature and the amount of ice and / or snow present and is preferably 15 to 80 g / m 2 of traffic area.
- the deicing agent can be applied with the usual spreading vehicles.
- the deicing agent according to the invention contains an alkali metal acetate, in particular potassium acetate.
- the amount of component a) is preferably between 47 and 53% by weight, in particular between 48 and 52% by weight.
- the deicing agent according to the invention preferably contains 0.01 to 0.5% by weight, in particular 0.02 to 0.2% by weight, of one or more surfactants.
- Alkyl (poly) glycosides are preferably used as surfactants. Their alkyl groups preferably comprise 8 to 16 carbon atoms.
- the deicing agent according to the invention preferably contains 0.0002 to 0.1% by weight, in particular 0.0005 to 0.01% by weight, of one or more defoamers.
- Polysiloxanes, in particular polydialkylsiloxanes, especially polydimethylsiloxanes, are preferably used as defoamers.
- the deicing agent according to the invention preferably contains 0.01 to
- Alkali phosphates, borates and silicates are preferably used as corrosion inhibitors.
- the icing protection time was determined analogously to ISO 11078 at the air and concrete slab temperature specified in each case. However, no electropolished aluminum sheets were used for freezing, but concrete slabs with the dimensions 25 cm x 25 cm x 5 cm and an inclination angle of 1 °. 1,875 g of the specified deicing agent were applied to the plates, which corresponds to an application rate of 30 g deicing agent / m 2 . The time until the icing of the concrete slab starts serves as a measure of the icing protection time.
- E deicing agent according to the invention, consisting of a 50% by weight aqueous solution of potassium acetate with 0.1% by weight of C 8 -C 6 -alkyl glycoside, 0.005% by weight of polydimethylsiloxane and 0.3% by weight of K 3 P0 4 . Potassium formate and potassium acetate were used for comparison purposes without additives.
