Problems solved by technology

Non-chlorine salt deicing agents include organic deicing agents such as acetates and urea. The main characteristics of this type of deicing agents are that they are expensive, rely on natural factors such as temperature and sunlight for snow melting, and have a long reaction time for snow melting.
At present, the environmentally friendly deicing agents recognized internationally are limited to acetate products, which have fewer types of raw materials, simple production technology, and environmental protection characteristics that are in line with my country's economic development policies. only a small amount of application

Abstract

The invention relates to an environment-friendly deicing agent and a preparation method thereof, belonging to the field of deicing agents. The environmentally-friendly deicing agent uses acetate and less corrosive chloride salts as main raw materials, and mainly includes methyl acetate, magnesium acetate and calcium acetate , prepared by adding a certain proportion of calcium chloride and magnesium chloride and a small amount of corrosion inhibitor. The invention effectively improves the common problem of high corrosion of common inorganic deicing agents, reduces the cost, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to an environment-friendly deicing agent and a preparation method thereof, in particular to a preparation formula and a preparation process of the environment-friendly deicing agent. Background technique [0002] Ice and snow in winter have always brought serious hidden dangers to traffic safety, and traffic accidents caused by ice and snow roads have caused huge economic losses and casualties. At present, snow removal methods are mainly divided into mechanical snow removal and chemical snow removal. Among them, mechanical snow removal is flexible, fast, and has a wide range of applications, but there are deficiencies such as poor removal rate and easy damage to the road surface; the snow removal method of chemical deicing agent can make up for the shortage of mechanical snow removal, and is an effective means of melting snow and ice. Its use is irreplaceable. The type and application amount of deicing agent are generally determ...
