Corrosion-resistant environment-friendly snow melting salt and preparation method thereof

Abstract

The invention discloses a corrosion-resistant environment-friendly snow melting salt which is prepared by mixing the following raw materials in parts by weight: 2-3 parts of acetic acid, 3-5 parts of potassium succinate, 4-6 parts of ammonium succinate, 10-17 parts of sodium gluconate, 30-41 parts of potassium dihydrogen phosphate, 1-2 parts of citric acid, 3-5 parts of quicklime, 1-2 parts of benzotriazole, 20-30 parts of scolecite, 60-80 parts of sodium chloride, 0.1-0.2 part of sodium 5-nitroguaiacolate, 0.1-0.13 part of calcium hexafluoroacetylacetonate, 5-7 parts of anhydrous sodium acetate, 4-6 parts of phosphoric acid and 0.01-0.02 part of coco fatty acid diethanol amide. The snow melting salt has the snow melting property, has the functions of removing NOx and SO2 generated by coal combustion and HCl generated by PVC (polyvinyl chloride) combustion, controlling the atmospheric pollution and the like, and greatly lowers the corrosion to the reinforced concrete pavements (bridges) and sewer lines. The sodium 5-nitroguaiacolate is added to improve the inhibitory effect on absorption of other nutrient elements by vegetable cells due to the increase of sodium ion concentration.

Description

technical field [0001] The invention relates to a salt, in particular to an anti-corrosion and environment-friendly deicing salt and a preparation method thereof. Background technique [0002] Extensive use of chlorine-containing salt deicing agents has caused great damage to plants, because plants have taken in excess Na + 、K + , Cl - Plasma increases the concentration of certain ions in plant cells, and the excessive absorption of these ions by plants inhibits the absorption of other plant nutrients, so that the types and concentrations of ions in plant cells also change, destroying the original Balance, this unbalanced absorption not only causes nutrient imbalance and inhibits growth, but also produces mono-salt poisoning. The salt water formed after the chlorine salt deicing agent melts with ice and snow will cause serious damage to reinforced concrete roads (bridges) and sewer pipes. damage. [0003] my country's research on deicing agents began in the mid-to-late 1...

Problems solved by technology

Although the non-chlorine salt deicing agent is developing rapidly, some developed countries can only apply it in a small amount due to the constraints of economic factors such as cost.
