Snow-melting agent

Abstract

The invention discloses a snow-melting agent. The snow-melting agent is prepared from the following raw materials in percentage by weight: 86% of sodium formate, 12% of sodium acetate trihydrate, 2% of urea and 0.001% of diethyl aminoethyl hexanoate. The snow-melting agent has the beneficial effects that the snow-melting agent does not contain pollution components such as halogen and heavy metal, has no influence on the ground environment and drinking water, is safe and environment-friendly, can provide nutrient substances such as nitrogen, phosphorus and potassium for vegetation while melting snow, can effectively promote growth of the vegetation, and is high in snow melting speed and low in cost; and the snow-melting rate of the snow-melting agent reaches up to 150%, snow blocks covering a road surface and vegetation can be quickly melted, the freezing point of the product mixed with water according to a ratio of 1: 5 is lower than -35 DEG C, the freezing point of the product mixed with water according to a ratio of 1: 10 is lower than -20 DEG C, the freezing point of the product mixed with water according to a ratio of 1: 15 is lower than -15 DEG C, the use performance of the snow-melting agent is stable, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of snow-melting agents, in particular to snow-melting agents. Background technique [0002] Deicing agent is a chemical that can reduce the melting temperature of ice and snow. Ordinary deicing agents are easy to get and cheap, and their main ingredients are chloride salts, nitrites and sulfates. Deicing agents melt the snow on the road by reducing the melting temperature of ice and snow, which is convenient for road dredging, and the effect of spreading is obvious. [0003] However, most of the existing snowmelting agents contain halogens and heavy metals and other pollutants, which cause the snowmelting agents to easily pollute the ground environment during use, affect people's drinking water safety, and are not conducive to the normal growth of vegetation. Secondly, the existing snowmelting agents The cost of the agent is high, and the snow melting rate is slow, which cannot meet the needs of rapid snow melting on...

Problems solved by technology

[0003] However, most of the existing snowmelting agents contain halogens and heavy metals and other pollutants, which cause the snowmelting agents to easily pollute the ground environment during use, affect people's drinking water safety, and are not conducive to the normal growth of vegetation. Secondly, the existing snowmelting agents The cost of the agent is high, and the snow melting rate is slow, which cannot meet the needs of rapid snow melting on roads and vegetation. The performance of the product in the snow melting process is not stable enough, and it is not convenient for large-scale promotion and application.
