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; 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.
