Embodiment 1

[0026] The technological process of preparation method of the present invention is as figure 1 As shown, specifically, the preparation method includes the following steps: 1). Preparation of anticoagulant: Take 1.56 grams of glycerol and 3 grams of boric acid, mix and heat to 160° C., maintain 160° C. for 1 hour, and keep stirring during the period. The stirring speed is 20 rpm. Take out the reactant, add 1.98 g of phosphoglyceride, 2 g of potassium formate, and 4 g of sodium acetate, mix and heat to 120° C., and keep it for 2 hours; keep stirring during the period, and the stirring speed is 25 rpm;

[0027] 2). Step 1) After the reaction is over, add 85 grams of sodium chloride, 0.5 grams of sodium hexametaphosphate as a slow-release antiscalant, stir evenly, extrude and granulate, and the extrusion pressure is 10 kg, and the finished product is produced. It is yellow-brown granular with a particle size of 0.3-0.6 cm.

Abstract

The invention discloses a low-chlorine environment-friendly snow melt agent without salt dust and a method for preparing the low-chlorine environment-friendly snow melt agent. The low-chlorine environment-friendly snow melt agent and the method have the advantages that the low-chlorine environment-friendly snow melt agent is in the shape of yellowish-brown particles, the particle size of the low-chlorine environment-friendly snow melt agent is 0.3-0.6 cm, the chlorine content of the low-chlorine environment-friendly snow melt agent is lower than the chlorine content of common snow melt agentsby 15% or above, environmental hazards of the low-chlorine environment-friendly snow melt agent can be reduced by 30%-40%, the low-chlorine environment-friendly snow melt agent contains little chloride, and accordingly destruction and pollution on soil, plants and underground water resources due to the low-chlorine environment-friendly snow melt agent are far lower than destruction and pollution due to the common snow melt agents; earth surfaces are free of white salt spots after snow removal operation is carried out, salt dust formation can be effectively inhibited, and secondary pollution can be prevented.

Description

technical field [0001] The invention belongs to the technical field of snow-melting agent preparation, and in particular relates to a salt-dust-free, low-chlorine, environment-friendly snow-melting agent and a preparation method thereof. Background technique [0002] Snowfall and icing in winter often bring inconvenience to cities and transportation, and easily cause traffic accidents, especially on expressways, which are likely to be forced to close due to snow or icing, resulting in huge economic loss. At present, snow removal methods are mainly divided into mechanical snow removal and chemical snow removal. Among them, mechanical snow removal is flexible, fast, and has a wide range of applications, but there are deficiencies such as poor removal rate and easy damage to the road surface; the snow removal method of chemical deicing agent can make up for the shortage of mechanical snow removal, and is an effective means of melting snow and ice. Its use is irreplaceable. ...
