Ceramic fiber-added compound snow-melting deicing agent special for urban roads and manufacturing method thereof

Abstract

The invention discloses a ceramic fiber-added compound snow-melting deicing agent special for urban roads. After sugarcane leaves and hemp palm barks are swelled and filled with polyacrylic acid emulsion, the cell walls are enhanced; the gaps in staggered fiber space is filled with the resins, so that the combination between fiber and fiber is enhanced; more micro-pores are introduced after carbonization, so that the adsorption capacity can be improved; according to the invention, glacial acetic acid is replaced by pyroligneous acid, modified fluorite powder is taken as calcium and magnesium precursor, the two materials are mixed to form the snow-melting agent, and the prepared snow-melting agent and anti-sliding auxiliaries are wrapped and pelletized and then are dried, so that the compound snow-melting deicing agent is acquired; the compound snow-melting deicing agent is added with the ceramic fibers, so that the strength is high and the compound snow-melting deicing agent is difficult to be crushed by automobiles; after the snow and ice are melted, the freezing point can be quickly reduced; the ceramic fiber-added compound snow-melting deicing agent can absorb heat so as to accelerate the snow melting; the residual liquid can be absorbed by the anti-sliding auxiliaries so as to prevent the pavement from being corroded; the method provided by the invention is low in cost, high in product fluidity and good in snow-melting effect.

Description

technical field [0001] The invention relates to the technical field of snow-melting agents, in particular to a special compound snow-melting and deicing agent for urban roads added with ceramic fibers 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, e...

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.
