Abstract

The invention discloses an economic environment-friendly snow melting agent and a preparation method of the economic environment-friendly snow melting agent. The economic environment-friendly snow melting agent is characterized by being mainly prepared from the following raw materials of acetate, low-corrosivity chloride and an anticorrosive which are taken as main raw materials, wherein the main raw materials are prepared from the following components in percentage by weight: 40 to 45 percent of calcium magnesium acetate, 20 to 25 percent of magnesium acetate and 10 to 25 percent of calcium acetate by adding 5 to 8 percent of calcium chloride in a certain proportion and 2.5 to 3.5 percent of anticorrosive. The economic environment-friendly snow melting agent and the preparation method of the economic environment-friendly snow melting agent, disclosed by the invention, have the advantages that the deicing performance is good, the freezing point is low, the corrosivity on materials such as metal and concrete of municipal infrastructures is small, the destructiveness on farmland and greening vegetation is extremely low, and the production technology is simple; due to the adoption of the preparation method for producing calcium acetate, magnesium acetate and calcium magnesium acetate by using waste acetic acid, the cost is effectively reduced, and the preparation method is suitable for being widely promoted.

Description

technical field [0001] The invention relates to an environment-friendly deicing agent and a preparation method thereof, belonging to the technical field of deicing agents, in particular to an economical and environment-friendly deicing agent and a preparation method thereof. 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. [0003] 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...
