preparation example Construction

[0042] The preparation method of described environment-friendly type non-chlorine salt deicing snow-melting agent comprises the steps:

[0043] Step 1) Weigh the main solvent, wetting co-solvent and corrosion inhibitor in the formula amount (if there is moisture absorption and agglomeration, it should be crushed and pulverized first), and then put the above raw materials into the mixer and mix them thoroughly to make them evenly dispersed;

[0044] Step 2) Add the mixture in step 1) into a double-roll granulator, and extrude and granulate to form flat spherical particles with a diameter of 5-20mm;

[0045] Step 3) The oblate spheroid particles in step 2) are packed into the warehouse by automatic packaging machine or manual measurement.

Embodiment 1

[0047] An environment-friendly non-chlorine salt deicing agent for melting snow and deicing is composed of 90% by weight of main solvent, 8% of wetting co-solvent and 2% of corrosion inhibitor; Salt and 10% sodium metasilicate uniformly mixed; wetting cosolvent is uniformly mixed with 40% by weight of borax and 60% urea; corrosion inhibitor is composed of 60% by weight of sodium gluconate and 40% % zinc sulfate uniformly mixed; the formate is made of the following raw materials by weight percentage: 70% potassium formate and 30% calcium formate are uniformly mixed.

[0048] The preparation method of described environment-friendly type non-chlorine salt deicing snow-melting agent comprises the steps:

[0049] Step 1) Weigh the main solvent, wetting co-solvent and corrosion inhibitor of the above formula, and then put the above raw materials into the mixer and mix them thoroughly to make them evenly dispersed;

Abstract

The invention provides an environment-friendly non-chlorine-salt snow melting and deicing agent and a preparation method thereof, and belongs to the field of snow melting and deicing. The environment-friendly non-chlorine-salt snow melting and deicing agent is characterized by comprising the following raw materials in percentage by weight: 60-90 percent of main solvent, 2-20 percent of wetting cosolvent and 2-20 percent of corrosion inhibitor, wherein the main solvent is prepared from 60-90 percent by weight of formate and 10-40 percent by weight of sodium metasilicate; the wetting cosolvent is prepared from 40 percent by weight of sodium borate or calcium nitrate and 60 percent by weight of urea or ammonium carbonate; the corrosion inhibitor is prepared from 60 percent by weight of sodium gluconate and 40 percent by weight of zinc sulfate. According to the environment-friendly non-chlorine-salt snow melting and deicing agent, the common problems of high corrosivity, serious impact on soil structures and the like of common inorganic chlorine salt snow melting agents can be effectively solved; after being used, the environment-friendly non-chlorine-salt snow melting and deicing agent can be naturally decomposed under the natural environment, and the cost of the non-chlorine-salt snow melting and deicing agent is lower than that of other organic salt (like acetates including potassium acetate, calcium magnesium acetate and the like) snow melting and deicing agents; therefore, the environment-friendly non-chlorine-salt snow melting and deicing agent is suitable for being used in places like domestic and overseas roads, airport pavements and streets, and has wide popularization and application prospects.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly non-chlorine salt deicing agent for melting snow and a preparation method thereof. It belongs to the field of snow melting and deicing. Background technique [0002] The accumulation of ice and snow in winter not only affects traffic, but also brings serious hidden dangers to traffic safety. Traffic accidents caused by ice and snow roads cause huge economic losses and casualties every year. At present, snow melting and deicing methods are mainly divided into mechanical snow removal and chemical snow removal. Mechanical snow and ice removal is fast and effective, but there are deficiencies such as poor removal rate and easily damaged road surfaces, and there are also limitations such as the inability to remove many places such as sidewalks; the snow melting and deicing method of chemical deicing agents can make up for the deficiencies of mechanical snow melting and deici...
