Abstract

The invention relates to a green environment-friendly snow-melting liquid and a preparation method thereof. The liquid contains the following components: 40-60 wt% of a soluble acetate; 10-20 wt% of a soluble formate; 2-5 wt% of a soluble carbonate; 1-5 wt% of a polyol; 1-5 wt% of a viscosity modifier; and 20-40 wt% of water. The green environment-friendly snow-melting liquid provided in the invention is free of chloride ions, has a fast snow-melting rate, has no corrosion on metal materials such as steel bars, and has no pollution on soil and water bodies, thus being green and environment-friendly. The snow-melting liquid is convenient for storage and transportation, and has wide application. Compared with most of existing solid snow-melting materials, the snow-melting liquid has the characteristics of fully mechanized spreading way, uniform spreading, labor cost reduction, and spreading time reduction, etc.

Description

technical field [0001] The invention relates to snow-melting materials, in particular to a green and environment-friendly snow-melting liquid and a preparation method thereof. Background technique [0002] Snowfall and icing in winter often bring inconvenience to urban transportation and can easily lead to traffic accidents. In particular, expressways are often closed and out of service due to freezing disasters, causing traffic interruptions and causing huge economic losses to the society. The use of deicing agents to remove road snow has been widely used in winter road snow removal practice because of its convenient use, low cost and fast melting rate. However, the destruction of some infrastructures such as roads and bridges by traditional chlorine salt deicing agents and the pollution to the environment will cause huge losses to the society. According to relevant information at home and abroad, the hazards of traditional deicing agents are mainly reflected in the follow...
