Special carbon fiber composite snow-melting deicing agent for airports and manufacturing method thereof

Abstract

The invention discloses a special carbon fiber composite snow-melting deicing agent for airports and a manufacturing method thereof. Eucalyptus leaves, lotus leaves and carbon fibers are swollen by an acrylic resin emulsion and filled to enhance the combination among fibers; after carbonization, more micropores are introduced, so the adsorption capacity is improved; wood vinegar used instead of glacial acetic acid and modified waste brick slag used as a metal precursor are mixed to obtain a snow melting agent; and finally, the snow melting agent and an antiskid aid are subjected to coating and granulation, and are dried to obtain the composite snow-melting deicing agent of which the toughness is greatly enhanced. After melting when contacting ice and snow, the composite snow-melting deicing agent can quickly lower the freezing point, and can absorb heat to increase the snow melting speed. The residual solution can be adsorbed by antiskid aid to avoid corroding the pavement. The method is simple to operate and easy to implement, has the advantages of low cost and obvious snow melting effect, increases the snow melting speed by 75% or above, can be automatically degraded, and does not damage the water body or environment after snow melting.

Description

technical field [0001] The invention relates to the technical field of snow melting agents, in particular to a special carbon fiber composite snow melting and deicing agent for airports 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, air...

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.
