Abstract

The invention discloses an inorganic-organic compound environment-friendly snow-melting agent. The inorganic-organic compound environment friendly snow-melting agent comprises the following components in parts by weight: 10-20 parts of anhydrous magnesium chloride or / and anhydrous calcium chloride, 10-20 parts of anhydrous sodium acetate or / and anhydrous potassium acetate and 0.1-5.0 parts of zinc sulphate. After the snow-melting agent disclosed by the invention is dissolved in water or snow, a freezing point of the snow-melting agent is below 0 DEG C, the freezing point of the anhydrous magnesium chloride after being dissolved in the water is minus 33 DEG C, and magnesium in underground water is increased, so as to be beneficial to human body; the freezing point of the anhydrous calcium chloride after being dissolved in the water is about minus 20 DEG C, and calcium in the underground water is increased, so that influence to human body is less; and the freezing point of acetic acid is about minus 30 DEG C; and a solidifying point of saline water is lower than that of the water, so that an ice cake is hardly formed after salt is dissolved in snow water. According to the inorganic-organic compound environment friendly snow-melting agent, the zinc sulphate forms a protective film on carbon steel, so that chloride ions can not corrode a metal bridge or a concrete pavement.

Description

technical field [0001] The invention relates to a snow removal material, more particularly to a snow melting agent. Background technique [0002] The ice and snow on the road in winter brings great safety hazards to traffic and people's travel. At present, mechanized snow removal has become the main force of urban snow removal. Therefore, in recent years, there have been a wide variety of deicing agents and deicing agents on the market, mainly chlorine salt deicing agents, including sodium chloride, potassium chloride, calcium chloride, magnesium chloride, etc. The heat-absorbing snow removal, on the other hand, utilizes the low freezing point of salt water. After the salt dissolves in the snow water, it is difficult to form ice cubes, which is beneficial to snow removal. This kind of deicing agent is cheap and can be widely used, but it is highly corrosive, easily corrodes metal and concrete, etc., and seriously damages large-scale public infrastructure.
