An environmentally friendly-non-corrosive road deicing agent

Abstract

The invention discloses an environmental-friendly non-corrosive road snow-melting agent, which is prepared from the following raw materials in parts by weight: 10 to 50 parts of potassium carbonate, 5to 20 parts of urea and 5 to 30 parts of 1,3-propanediol. The snow-melting agent can be sprayed onto the pavement in advance before the ice and snow coming; the freezing point of the ice and snow onthe road can be effectively lowered. The snow-melting agent is used for melting ice and snow in a pre-wetting mode; the snow-melting time is shortened. The snow-melting agent uses potassium carbonateinorganic salt as the major snow-melting ingredients; corrosion metal Cl<-> is not contained; the corrosion of the snow-melting agent on the metal and concrete can be effectively prevented. The snow-melting agent provided by the invention has low icing point; ice and snow are enabled to flow away in a liquid-state water form without generating ice on the road; the driving safety is guaranteed.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly and non-corrosive road deicing agent. Background technique [0002] In recent years, due to the continuous deterioration of the environment, snowfall and icy roads have occurred from time to time in winter, which have become the biggest "black spots" that cause serious traffic congestion and road traffic accidents in the city. Especially viaducts and overpasses, in cold rainy and snowy weather, because the bridge deck is water or suspended, the temperature is usually lower than that of the road, so it is more likely to cause the bridge deck to freeze, significantly reduce the road friction coefficient, and easily cause road traffic. ACCIDENT. [0003] Complex weather conditions have seriously affected the condition of the road surface. Snow, frost, thin ice and other situations occur from time to time, which bring huge risks to the driving of vehicles, which not only se...

Problems solved by technology

[0005] The use of solid snow melting agent also has disadvantages, mainly in the following aspects: first, when the solid snow melting agent is spread, the road surface is slippery, and the waste caused by popping off the road surface and splashing into the shoulder of the road is huge; second, the dry snow melting agent is spread on the snow When it needs to absorb heat and moisture, if it does not absorb enough heat and moisture, the solid deicing agent will not react chemically; third, it takes a long time for the solid deicing agent to melt ice and snow, especially in low temperature climates
