Abstract

The invention provides a compound salt for melting ice and snow, which comprises three, four, five or six kinds of organic or inorganic minerals selected from calcium nitrate, sodium nitrate, calcium chloride, magnesium chloride, sodium chloride, postassium acetate, sodium metasillcate, sodium molybdate, tertiary sodium phosphate, sodium benzoate, 5-chloro benzotriazole and benzimidazole allyl sulphide.

Description

[0001] The invention has remarkable ice and snow melting, ice melting and snow removal effects, wide application range, simple and convenient preparation method, and meets environmental protection requirements. 1. Technical field [0002] The invention belongs to the category of chemistry and belongs to the technical field of organic and inorganic compound salts. 2. Background technology [0003] 1. Understanding of the invention of "melting ice and snow" [0004] The melting of ice and snow of the present invention and the currently used deicing agent, whether solid or liquid, are all for the purpose of lowering the freezing point of water. Its ice-melting and snow-removing mechanism belongs to the chemical category and belongs to the technical field of organic and inorganic compound salts. It utilizes the water absorption of melting ice and snow and the large amount of heat released during melting to displace the structural lattice in the ice and snow, resulting in meltin...
