Abstract

The invention relates to a preparation method of an environment-friendly organic composite salt snowmelt agent. According to the method, humic acid is compounded with sodium ions to form a humic acid associated complex, i.e. the organic composite salt snowmelt agent causing low corrosion to carbon steel and rubber is formed. The snowmelt agent has the advantages of low corrosion, low freezing point and good snow melting effect, and effectively solves the problems of salt damage to vegetation, water pollution and soil hardening. In addition, the snowmelt agent has an anti-skidding effect for the road. The selected materials for preparing the snowmelt agent are commercially available products which are low in price and easy to obtain, so that the snowmelt agent provided by the invention is suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of deicing agent research, and in particular relates to a preparation method of an environment-friendly organic compound salt deicing agent. Background technique [0002] Snow-melting agent is a kind of salt substance. Commonly used snow-melting salts are chloride salts, such as calcium chloride, magnesium chloride and sodium chloride, etc. However, a large amount of chlorine salt will cause certain damage to metals, road surfaces and plants on both sides of the road. [0003] The preparation method of deicing agent provided by US Patent No. 6149833 is a mixture of sodium formate, sodium chloride and a small amount of corrosion inhibitor. This invention measures the corrosion rate and achieves good results. The deicing agent can be made into nano-scale solid particles or formulated into a certain proportion of solution for use. However, the addition of corrosion inhibitor greatly increases the difficulty of...
