Problems solved by technology

The snow melting agent melts the snow on the road by reducing the melting temperature of ice and snow, which is convenient for road dredging, and the effect of spreading is obvious, but it is harmful. Research has found that the residue of the snow melting agent can corrode the road surface and automobile rubber tires

Abstract

The invention discloses an environmental protection snow melting agent and a preparation method therefor, and relates to the snow melting agent technology field. The snow melting agent is mainly prepared from magnesium phosphate, urea, carbon black, potassium acetate, sodium acetate, silver nitrate, hexadienoic acid, wheat bran, sodium metasilicate, maltose, sodium peroxide, hexamethylenetetramine, silica-gel powder, DL-411 aluminum acid ester coupling agent, water and antiskid auxiliary agents. The snow melting agent employs anhydrous sodium metasilicate and magnesium phosphate to cooperate with each other, anhydrous sodium metasilicate has a strong magnesium ion complexing capability, through cooperation, the chemical properties are stable, the ice-resistant capability is strong, and the snow melting effect is good. The potassium acetate component is added, and low corrosion to pavements and soil, low toxicity and environmental protection are achieved. The components of the antiskid auxiliary agents, silica gel, maltose and the like protect pavements and have antiskid and sterilization functions.

Description

technical field [0001] The invention relates to the technical field of snow-melting agents, more specifically to an environment-friendly snow-melting agent and a preparation method thereof. Background technique [0002] Deicing agent is a kind of chemical. Ordinary deicing agent raw materials are easy to get and the price is low. Its main ingredients are potassium acetate and chloride salt, and they are classified according to these two kinds. The deicing agent melts the snow on the road by reducing the melting temperature of ice and snow, which is convenient for road dredging, and the effect of spreading is obvious, but it is harmful. Studies have found that the residue of the deicing agent can corrode the road surface and automobile rubber tires. At present, in the north, sand and snow plows are still used as the main method in winter, and snow-melting agents are used as a supplementary method to remove ice and snow on the road surface to ensure smooth traffic.
