Low-corrosivity environmentally-friendly compound antiskid snow-melting agent and preparation method thereof

Abstract

The invention discloses a low-corrosivity environmentally-friendly compound antiskid snow-melting agent and a preparation method thereof. The snow-melting agent is prepared from the following raw materials in parts by weight: 45 to 55 parts of inorganic salt, 35 to 42 parts of organic salt, 1 to 2 parts of a corrosion inhibitor and 8 to 10 parts of an adsorbent. The adsorbent is bentonite, and the corrosion inhibitor is sodium phosphate. The inorganic salt is prepared from the following raw materials in parts by weight: 20-25 parts of calcium chloride and 25-30 parts of ammonium chloride. The organic salt is urea. Preferably, the snow-melting agent is prepared from the following raw materials in parts by weight: 45 parts of inorganic salt, 40 parts of organic salt, 1 part of the corrosion inhibitor and 8 parts of the adsorbent. The preparation method of the low-corrosivity environmentally-friendly snow-melting agent provided by the invention is simple, and is conducted at normal temperatures and pressures; the method is mild in condition, the raw materials are easy to get, sources are wide, and industrial production is easy to realize; and moreover, the snow-melting agent has the advantages of low price, high snow melting speed and the like, and is applicable to large-scale popularization.

Description

technical field [0001] The invention belongs to the field of snow-melting agents, and in particular relates to a low-corrosion and environment-friendly composite anti-skid snow-melting agent and a preparation method thereof. Background technique [0002] In the case of light snow in winter, it is suitable to use snow melting agent to melt snow. The basic components of snow melting agent include salt, which can be divided into organic salt and inorganic salt. Among them, the amount of inorganic salt is more, and most of them are chloride salt. This kind of salt is harmful to soil and metal. All have corrosive effects, especially irreversible damage to the soil. In order to avoid the salinization damage caused by the deicing agent to the soil and cause plant growth problems, organic salts are generally used instead of inorganic salts, but the cost of organic salts is higher than that of inorganic salts. It is much higher, and the proportion of organic salts in practical applic...
