Environment-friendly snow-melting agent and preparation method thereof

Abstract

The invention relates to an environment-friendly snow-melting agent and a preparation method thereof, belonging to the technical field of snow-melting agents. The snow-melting agent mainly comprises the following raw materials in parts by weight: 5-35 parts of ginger juice, 2-8 parts of ionic liquid, 0.8-4.6 parts of n-butyl alcohol and 0.2-2.6 parts of ethyl acetate. The invention also provides the preparation method of the snow-melting agent. The preparation method comprises the following steps: (1) preparing the ginger juice; (2), (3) and (4) preparing the snow-melting agent. The novel snow-melting agent provided by the invention has the beneficial technical effects that the raw materials are easy to obtain; the cost is low; the snow-melting agent has high snow melting efficiency and conduces to solving the problem of corrosion of road and bridge reinforcements caused by traditional snow melting products; the impacts and damages of the snow-melting agent on roads and environments are furthest reduced; the snow-melting agent is applicable to the low-temperature environment at minus 50 DEG C and has a wider application range of environments.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly deicing agent and a preparation method thereof. Background technique [0002] Traditional deicing agents are chlorine-salt deicing agents, which consist of or contain inorganic chlorine salts such as sodium chloride, magnesium chloride, and calcium chloride, among which calcium chloride is the main active ingredient. Due to the corrosiveness of Clˉ, rust inhibitors (anticorrosion agents) are often added, although the corrosion to metals and road construction materials is alleviated, but the corrosion is still very prominent, and Clˉ will have an impact on soil and vegetation, harming plants grow. In view of this, the chlorine salt type deicing agent was later improved, such as the patent application number 201410512480.X, the patent name is: a low-corrosion and high-efficiency chlorine salt deicing agent and its preparation method, and a low-corrosion and high-efficienc...

Problems solved by technology

Due to the corrosiveness of Clˉ, rust inhibitors (anticorrosion agents) are often added, although the corrosion to metals and road construction materials is alleviated, but the corrosion is still very prominent, and Clˉ will have an impact on soil and vegetation, harming plants to grow

In view of this, the chlorine salt type deicing agent was later improved, such as the patent application number 201410512480.X, the patent name is: a low-corrosion and high-efficiency chlorine salt deicing agent and its preparation method, and a low-corrosion and high-efficiency chlorine salt deicing agent is disclosed. agent, which is prepared by weight ratio from 85-98% sodium chloride, 1-10% corrosion inhibitor, and 1-5% additives. Although it solves the corrosion problem to a certain extent, it is harmful to soil, water sources, plants and The damage to aquatic animals has not been solved; it is not an environmentally friendly deicing agent in the true sense

All kinds of environmentally friendly deicing agents that appeared successively later could not get rid of inorganic salts, and failed to fundamentally solve the problems of environmental protection and environmental friendliness.
