Problems solved by technology

[0003] The deicing agent melts the snow on the road by reducing the melting temperature of ice and snow, which is convenient for road dredging, and the effect of spreading is obvious. The commonly used deicing agent is mainly composed of "chloride salt", such as sodium chloride, calcium chloride, magnesium chloride, Potassium chloride, etc., but it is harmful. Studies have found that although chlorine salt deicing agents are convenient for deicing and snow melting, and the price is also cheap, the snow after using the deicing agent is often piled up on the green belt or farmland on both sides of the road. After the beginning of spring, all the salt residues are accumulated in the farmland and green belts, making the soil salinized and destroying vegetation. Crops and trees are afraid of salt, which will cause a large number of green plants to die, and the harm is even destructive. If the plants are planted, all the soil must be replaced, and the farmland is even more doomed. The loss is self-evident, and the residue of this kind of chlorine salt deicing agent will also corrode the road surface and the rubber tires of the car.
[0004] Invention patent CN 106318319 A discloses a new type of deicing aerosol, which contains: ethylene glycol, polyethylene glycol monomethyl ether, sodium dodecylbenzenesulfonate, fatty acid glycerides, fatty alcohol polyoxyethylene ether, P-toluenesulfonic acid, isopropanol, triethanolamine, deionized water and other components, but its application range is limited, the effect of melting ice is average, and it cannot remove ice on the road well
In addition, the invention patent CN 103805139 A discloses a deicing aerosol, which is made of ethanol, sodium tetraborate, menthol, triethanolamine, sodium sulfate, propellant, xanthan gum, distilled water and other raw materials. Deicing spray does not play a good role in deicing, and its application is also limited

Description

Technical field [0001] The invention relates to the technical field of road deicing agents, in particular to a high-efficiency road deicing agent and a preparation method thereof. Background technique [0002] Snowfall in winter is a common natural phenomenon. However, in some areas, the temperature is low, and the snow on the road is difficult to melt. After the snow on the road is compacted by vehicles, the friction between the wheels and the road surface is reduced, and the car is easy to slide left and right. At the same time, The braking distance of a car is also difficult to control. Once the car speeds too fast or turns too fast, traffic accidents may occur. Even if the snow melts at noon when the sun is full, it will freeze due to the low temperature, and complex weather conditions are serious. Affects the condition of the road surface. Snow, frost, thin ice, etc. occur from time to time, which brings huge risks to vehicle driving, which not only seriously affects the smo...
