High-adsorption composite snow melting and deicing agent and manufacturing method thereof

Abstract

The invention discloses a high-adsorption composite snow melting and deicing agent. After smashed corn cob and mushroom residues are subjected to swelling and filling by means of waterborne perfluorocarbon emulsion, cell walls are enhanced, gaps between staggered fibers are filled with the emulsion, bonding between the fibers is enhanced, and many micropores are introduced after carbonization so that adsorption capacity can be improved. Meanwhile, wood vinegar takes the place of glacial acetic acid, modified talcum powder serves as a calcium magnesium precursor, the wood vinegar and the modified talcum powder are mixed to prepare a snow melting agent, and then the prepared snow melting agent and an anti-slip auxiliary are wrapped, granulated and dried to obtain the composite snow melting and deicing agent. The composite snow melting and deicing agent is low in cost and can quickly reduce the freezing point after ice and snow are melted, and residual liquid can be absorbed by the anti-slip auxiliary to prevent a pavement from being corroded. The application temperature range is wide, solar energy can be absorbed after activated carbon is added, and energy is provided for snow melting and deicing.

Description

technical field [0001] The invention relates to the technical field of snow-melting agents, in particular to a high-adsorption composite snow-melting and deicing agent and a preparation method thereof. Background technique [0002] Ice and snow in winter are a factor that seriously affects transportation. Ice and snow on roads are an important safety hazard that affects traffic operations in winter in most parts of our country, which greatly reduces transportation capacity and is likely to cause traffic accidents. It has become a key problem that needs to be solved urgently for smooth traffic operation in winter in my country, and deicing agent is produced accordingly. [0003] As the name implies, deicing agent is a salt used to lower the freezing point of ice and snow. Its function is to melt snow and ice. Because of its simple use, good deicing and snow melting effect and many other advantages, it is mainly used as a base for urban roads, expressways, airports, ports, brid...

AI Technical Summary

Problems solved by technology

[0005] At present, the existing deicing agent has two forms: powder and liquid. The liquid is sprayed on the ice and snow surface in an atomized manner to melt the ice and snow. It is evenly dispersed but easily penetrates into the road surface, which will cause certain corrosion damage. The powder form is directly sprinkled on the snow surface. It melts snow, but its strength is low and the density is small, and it is easy to be blown away by the wind, resulting in uneven dispersion and a decline in the snow-melting effect. It has good heat absorption and adsorption performance, accelerates the speed of snow melting and deicing, and has the characteristics of low corrosion, little pollution, little damage to plants, high comprehensive performance, multiple functions, and convenient storage.
