preparation example Construction

[0042] The preparation method of the environment-friendly non-chlorine salt snow melting deicer includes the following steps:

[0043] Step 1) Weigh the main melting agent, wetting aid and corrosion inhibitor of the formula (if moisture-absorbing agglomeration is firstly crushed and powdered), then put the above-mentioned raw materials into a mixer to fully stir and mix to make them uniformly dispersed;

[0044] Step 2) Add the mixture of step 1) to a pair-roll granulator to perform extrusion granulation to form oblate spherical particles with a diameter of 5-20 mm;

[0045] Step 3) Put the oblate spherical particles of step 2) into the warehouse through automatic packaging machine or manual metering and packaging.

Embodiment 1

[0047] An environmentally friendly non-chlorine salt snow melting deicing agent, which is composed of 90% by weight of a main melting agent, 8% of a wetting aid and 2% of corrosion inhibitor; the main melting agent is composed of a weight percentage of 90% formate and 10% sodium metasilicate are uniformly mixed; wetting aid is uniformly mixed with 40% borax and 60% urea by weight; corrosion inhibitor is made from 60% glucose by weight Sodium and 40% zinc sulfate are uniformly mixed; the formate is made from the following raw materials in weight percentage: 70% potassium formate and 30% calcium formate are uniformly mixed.

[0048] The preparation method of the environment-friendly non-chlorine salt snow melting deicer includes the following steps:

[0049] Step 1) Weigh the main melting agent, wetting aid and corrosion inhibitor in the above formula, and then put the above raw materials into a mixer to fully stir and mix to make them uniformly dispersed;

[0050] Step 2) Add the mix...

Embodiment 2

[0054] An environmentally friendly non-chlorine salt snow melting deicing agent, which is composed of 60% by weight of main melting agent, 20% of wetting aid and 20% of corrosion inhibitor; said main melting agent is composed of 60% by weight 60% formate and 40% sodium metasilicate are uniformly mixed; the wetting aid is uniformly mixed with 40% calcium nitrate and 60% ammonium carbonate by weight; the corrosion inhibitor is 60% by weight Sodium gluconate and 40% zinc sulfate are uniformly mixed; the formate is made from the following raw materials in weight percentage: 30% potassium formate and 70% calcium formate are uniformly mixed.

[0055] The preparation method is the same as in Example 1.

[0056] This product is a universal environmental snow melting deicer.

Abstract

The invention provides an environment-friendly non-chlorine salt snow melting and deicing agent and a preparation method thereof, belonging to the field of snow melting and deicing. The environment-friendly non-chlorine salt snow-melting and deicing agent is characterized in that it is composed of the following raw materials by weight percentage: 60-90% of the main melting agent, 2-20% of the wetting and melting aid and 2-20% of the corrosion inhibitor agent; the main melting agent is composed of 60%-90% formate and 10-40% sodium metasilicate by weight percentage; the wetting aid is 40% borax or calcium nitrate and weight percentage The percentage is composed of 60% urea or ammonium carbonate; the corrosion inhibitor is composed of 60% by weight of sodium gluconate and 40% of zinc sulfate. The invention effectively improves the common problems of common inorganic chlorine salt deicing agents such as high corrosivity and serious impact on soil structure, and can be naturally decomposed in the natural environment after use, and the cost is lower than that of other organic salts (such as potassium acetate, calcium magnesium acetate, etc. Acetates) snow melting and deicing agents are suitable for snow melting and deicing on roads, airport runways, streets and other places at home and abroad, and have good prospects for popularization and application.

Description

Technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly non-chlorine salt snow melting deicing agent 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 icy and snowy 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 deicing is fast and efficient, but it has disadvantages such as poor de-cleaning rate and easy damage to the road surface. There are also restrictions on many places such as sidewalks that cannot be removed; chemical deicing agents can make up for the lack of mechanical deicing. , Is an effective means of melting snow and ice. [0003] The type and application am...
