Problems solved by technology

In the prior art, inorganic phosphate is usually used as an anti-corrosion agent, but the obvious disadvantage of inorganic phosphate is that it will form calcium scale with calcium ions in the water, which needs to be used together with scale inhibitors, and the discharge of the phosphate into the water can promote water algae growth, which can easily cause eutrophication of water quality

Abstract

The invention discloses an environment-friendly snow melting agent and a preparation method thereof. The agent is prepared from, by weight, 85-90 parts of formate, 8-10 parts of polylactic acid, 3-5 parts of a carbon nanotube, 2-3 parts of chitosan, 1-2 parts of metaphosphate and 3-5 parts of sodium gluconate; the metaphosphate is one of sodium hexametaphosphate, potassium metaphosphate or calciummetaphosphate. The snow melting agent has the advantages that the ability to melt snow and ice is strong, there is no corrosive effect, and the agent does not cause damage to soil and a water body after melting, has a certain nourishing effect, does not cause secondary pollution to a city and is an eco-friendly snow melting agent.

Description

technical field [0001] The invention relates to a snow-melting agent and a preparation method thereof, in particular to an environment-friendly snow-melting agent and a preparation method thereof, belonging to the technical field of snow-melting agents. Background technique [0002] Snowfall and icing in winter often bring inconvenience to cities and transportation, and easily cause traffic accidents, especially on expressways, which are likely to be forced to close due to snow or icing, resulting in huge economic loss. At present, snow removal methods are mainly divided into mechanical snow removal and chemical snow removal. Among them, mechanical snow removal is flexible, fast, and has a wide range of applications, but there are deficiencies such as poor removal rate and easy damage to the road surface; the snow removal method of chemical deicing agent can make up for the shortage of mechanical snow removal, and is an effective means of melting snow and ice. Its use is i...
