Non-chlorine environment-friendly snow-melting agent

Abstract

Belonging to the technical field of snow-melting agents, the invention relates to a non-chlorine environment-friendly snow-melting agent, which adopts organic salt as the main components and does notcontain chlorine element. Sodium formate, urea, potassium acetate, sodium carbonate, montmorillonite, sodium tetraborate and alkyl phenol polyoxyethylene ether are used as the raw materials, and by means of crushing, mixing, granulation, screening and packaging, the product can be obtained. Compared with the existing products, the non-chlorine environment-friendly snow-melting agent provided by the invention has the characteristics of good snow-melting effect, fast snow-melting speed, long snow-melting time, high forming rate, no chlorine, no harm to facilities, vehicles, plants, water bodiesand the like, no odor, salting or slip after spreading, and high cost performance.

Description

technical field [0001] The invention relates to a deicing agent. Specifically, the invention relates to an environment-friendly deicing agent with organic salt as the main component and no chlorine element. Background technique [0002] There are two types of deicing agent, chlorine salt type and non-chlorine salt type. [0003] Chlorine-salt deicing agent has a wide range of sources and is cheap, and is the most commonly used deicing agent. However, the chloride ion has a small radius and strong penetrating power, which can destroy the protective layer of the metal surface, causing pitting corrosion and stress corrosion cracking of the metal, which is very harmful to infrastructure and driving vehicles. A large amount of chloride ions contained in the chlorine salt deicing agent will block the penetration of water when it penetrates into the soil. Once the chlorine content in the roots of the vegetation is too high, the branches and leaves will wither and die, destroying ...

AI Technical Summary

Problems solved by technology

However, the chloride ion has a small radius and strong penetrating power, which can destroy the protective layer of the metal surface, causing pitting corrosion and stress corrosion cracking of the metal, which is very harmful to infrastructure and driving vehicles

A large amount of chloride ions contained in chlorine salt deicing agent will block the penetration of water when it penetrates into the soil. Once the chlorine content in the root of the vegetation is too high, the branches and leaves will wither and die, destroying the green vegetation around the road and causing serious damage.

In addition, after the chlorine-salt deicing agent is dissolved in ice and snow, it is discharged into the sides of the road and the surrounding farmland, which makes the surface salinized, pollutes the surface water and groundwater, and affects the ecological balance.

[0004] At present, the non-chloride deicing agents mainly include organic salts such as potassium acetate and calcium magnesium acetate, which cannot be used on a large scale like the chloride deicing agents, mainly in the following aspects: First, the price of acetate The second is that it will emit a pungent sour smell after sowing, the third is that after the acetate is dried, it will leave salt stains on the ground and affect the appearance of the city, and the fourth is that calcium and magnesium acetate will cause water pollution

Therefore, the non-chlorine salt type deicing agent can only be applied to snow removal in airports etc. at present, and cannot be used in a large area

[0005] Although the environmentally friendly deicing agents that have appeared in recent years no longer use sodium chloride as the main component, but use calcium chloride or magnesium chloride, etc., and then introduce corrosion inhibitors, etc., but from a chemical point of view, the chlorine element still exists, and it has not completely improved its effect on the deicing agent. environmental hazards
