Problems solved by technology

[0002] Existing snow-melting agents use chlorine salts, such as one or more of sodium chloride, calcium chloride, magnesium chloride, and potassium chloride. The main advantages of chlorine salts as snow-melting agents are lower cost and better snow-melting effect Good, but the chlorine ions in the chlorine-salt deicing agent are too high, and a large amount of chloride ions remaining on the road surface after snow melting will corrode the road surface...

Embodiment Construction

[0012] The present invention will be further described below in conjunction with embodiment.

[0013] The inventor scientifically and rationally selects raw materials: wherein: the performance of potassium acetate is: white crystalline powder, mostly in the form of fine particles or powder, with a relative density of 1.570 and a melting point of 292° C., which is very soluble in water; the performance of urea is: colorless or White needle-like or rod-like crystals, industrial or agricultural products are white slightly reddish solid particles, odorless and tasteless, density 1.335g / cm3, melting point 132.7°C, soluble in water, slightly alkaline; properties of sodium hypophosphite: White crystals with pearly luster, easily soluble in water, relatively stable in dry state; properties of sodium gluconate: white crystalline particles or powder, easily soluble in water, mainly used as an acid-base balance agent.

[0014] See the table below for the weight proportions of the raw mat...

Abstract

The invention relates to an environment-friendly snow melting agent and a preparation method thereof; the environment-friendly snow melting agent is prepared from the following raw materials according to the weight ratio: 16 to 24 parts of potassium acetate, 10 to 14 parts of urea, 3 to 5 parts of sodium hypophosphite and 3 to 5 parts of sodium gluconate. The raw materials contain no corrosive materials, are no harm to road surfaces, soil, water and the health of people and are beneficial to the environmental protection; the snow melting agent has the advantages of better snow melting effect, relatively low cost, wide popularization and application value; and the preparation method is simple and is beneficial to mass production.

Description

technical field [0001] The invention relates to a deicing agent, which is an environment-friendly deicing agent and a preparation method thereof. Background technique [0002] Existing snow-melting agents use chlorine salts, such as one or more of sodium chloride, calcium chloride, magnesium chloride, and potassium chloride. The main advantages of chlorine salts as snow-melting agents are lower cost and better snow-melting effect Good, but the chlorine ions in the chlorine-salt deicing agent are too high, and a large amount of chloride ions remaining on the road surface after snow melting will corrode the road surface, seriously damaging the service quality and life of the road; The concentration of a single salt ion in the snow water is too high, the solubility is large, and the dissolution rate is too fast, which will cause excessive accumulation in the surrounding soil and easily cause soil and groundwater pollution, affecting plant growth and people's health.
