Problems solved by technology

Although the formula does not use sodium chloride as a deicing agent, it uses sulfate, which is also corrosive to buildings. In addition, the use of a large amount of phosphate will cause eutrophication of the soil, especially the water source

Embodiment 1

[0027] The formula is: 90 parts by weight of ionic liquid and 10 parts by weight of sodium gluconate are mixed into a snow-melting and deicing agent, wherein the structure of the ionic liquid is:

[0028]

[0029] Take two 150ml ceramic crucibles with the same diameter and height, add 100ml of deionized water, and then place them in a low-temperature constant temperature refrigerator at -10°C ± 1°C to freeze until frozen. Pipette 25ml of the snow-melting and deicing agent of Example 1. Snow-melting de-icing agent and traditional sodium chloride solution (reference solution). Put it into a 50ml beaker, and also place it in a low-temperature constant temperature refrigerator at -10°C ± 1°C for 12 hours before use. Take out the ceramic crucible with ice cubes from the above-mentioned refrigerator, wipe the water on its surface quickly with a cloth, weigh, and the mass is accurate to 0.1g. Pour the snow-melting and deicing agent containing Example 1 into the crucible quickly,...

Embodiment 2

[0031] The formula is: 95 parts by weight of ionic liquid and 5 parts by weight of sodium carbonate are mixed into a snow-melting and deicing agent, wherein the structure of the ionic liquid is:

[0032]

[0033] Take two 150ml ceramic crucibles with the same diameter and height, add 100ml of deionized water, and then place them in a low-temperature constant temperature refrigerator at -10°C ± 1°C to freeze until frozen. Pipette 25ml of the snow-melting and deicing agent of embodiment 2. Snow-melting de-icing agent and traditional sodium chloride solution (reference solution). Put it into a 50ml beaker, and also place it in a low-temperature constant temperature refrigerator at -10°C ± 1°C for 12 hours before use. Take out the ceramic crucible with ice cubes from the above-mentioned refrigerator, wipe the water on its surface quickly with a cloth, weigh, and the mass is accurate to 0.1g. Quickly pour the ionic liquid deicing agent of the present invention into the crucibl...

Embodiment 3～5

[0035] Take a 150ml ceramic crucible with the same diameter and height, add 100ml deionized water, and place it at -10 ℃ ±1 ℃ Freeze in a low temperature freezer until frozen. Then the crucible that has been frozen is at different temperatures, add the snow melting and deicing agent of 50g embodiment 1 or embodiment 2 to do snow melting and deicing experiment, the results are as follows:

[0036]

[0037] It can be seen from the above experimental results that the deicing efficiency of the ionic liquid snow melting and deicing agent is much higher than that of the traditional sodium chloride solution, especially when the temperature is lower.

Abstract

The invention relates to an environmentally-friendly runway snow melting and deicing agent. The snow melting and deicing agent is suitable for snow melting and deicing of parking aprons and airport runways. The snow melting and deicing agent is characterized by containing 90-95% of ionic liquid and 5-10wt% of a synergist which is sodium gluconate or sodium carbonate. The snow melting and deicing agent can remove floating ice on a runway surface, and contains no chloride ion. The dosage is small. The snow melting and deicing agent has no corrosion destruction effect on concrete and steel bars. In addition, the snow melting and deicing agent can prevent second icing of pavements because of day and night temperature difference effectively.

Description

technical field [0001] The invention relates to an environmentally friendly runway snow melting and deicing agent. Background technique [0002] The icing of airport runways and aprons is a major safety hazard that affects aviation flight safety. In the history of my country's civil aviation, there have been several accidents and incidents in which the runway was slippery due to water accumulation, icing and snow accumulation on the runway. [0003] Some runway icing is caused by the freezing of supercooled raindrops or supercooled drizzle drops on the runway surface; some are caused by the melting of snow on the runway or freezing of rainwater. When there is ice on the runway, the friction between the tires of the aircraft and the ice layer is very small, and it is difficult for the taxiing aircraft to maintain its direction, and it is easy to run off the runway. [0004] When there is snow on the runway, the snow should generally be removed in time. Although the manuals...
