Environment-friendly deicing fluid and applications thereof in road deicing

Abstract

The invention provides environment-friendly deicing fluid and applications of the environment-friendly deicing fluid in road deicing. The invention discloses the environment-friendly deicing fluid, the deicing fluid contains a fermentation product and salt, wherein for 100 weight parts of the fermentation product, the content of salt is 12-50 weight parts, and the salt is organic salt and/or inorganic salt; the fermentation product is prepared through the method comprising the following steps: (1) inoculating a microbial strain capable of producing 1,3-propanediol into a culture medium containing glycerol, thus obtaining a material before fermentation; and (2) carrying out anaerobic culture on the material before fermentation in the step (1) till the concentration of 1,3-propanediol is 50-500 g/L, thus obtaining the fermentation product. During the preparation process of the environment-friendly deicing fluid, no environmental pollution is generated, the environment-friendly deicing fluid can naturally degrade in the environment and causes no damage to the road and the surrounding facilities, and thus the problem that during the snow melting and ice melting processes adopting the existing deicing fluid, environmental pollution and corrosion to the road facilities are caused, is solved, meanwhile, the snow melting and ice melting speeds are accelerated, the protection time is increased, the work of the mechanical spraying vehicle is effectively matched, and the manual operation is reduced.

Description

technical field [0001] The invention relates to a deicing fluid, in particular to an environment-friendly deicing fluid and its application in road surface deicing. Background technique [0002] Ice and snow weather in winter has a serious impact on road traffic conditions. Roads in northern regions are easily affected by snow, while roads in southern regions are easily affected by freezing in winter. Severe weather such as snow accumulation and freezing rain not only affect the traffic of vehicles, but also easily cause traffic accidents and cause casualties. In addition to mechanical or manual snow and ice removal, traditional pavement maintenance in winter also uses chemical snow removal methods. Currently commonly used snow and deicing agents are mainly chlorine salt products, which cause a certain degree of corrosion and damage to metal facilities such as roads, bridges and culverts, sewage pipelines, asphalt and cement concrete roads, bridges, greening and natural env...
