Example Embodiment

[0014] Example 1:

[0015] The environmental protection snow remover is composed of the following components in the following weight ratio:

[0016] Calcium chloride: urea: sodium nitrite: potassium sulfate: sodium metasilicate: carbon black = 110:15:15:10-15:22:90.

[0017] The preparation method of the environmental protection snow remover is:

[0018] Take the above-mentioned raw materials according to the proportion and mix them thoroughly and then add them to 60℃ water to make a saturated solution.

Example Embodiment

[0019] Example 2:

[0020] The environmental protection snow remover is composed of the following components in the following weight ratio:

[0021] Calcium chloride: urea: sodium nitrite: potassium sulfate: sodium metasilicate: carbon black = 90-110: 15-25: 15-25: 10-15: 22-30: 50-90.

[0022] The preparation method of the environmental protection snow remover is:

[0023] The temperature of the water used to make the saturated solution was 80°C, and the rest was the same as in Example 1.

Example Embodiment

[0024] Example 3:

[0025] The environmental protection snow remover is composed of the following components in the following weight ratio:

[0026] Calcium chloride: urea: sodium nitrite: potassium sulfate: sodium metasilicate: carbon black = 100:20:20:12:25:70.

[0027] Method for preparing environmental protection snow remover:

[0028] The temperature of the water used to make the saturated solution was 70°C, and the rest was the same as in Example 1.

Abstract

The invention relates to an environmentally friendly snow melting agent which comprises the following components in percentage by weight: 90-110 percent of calcium chloride, 15-25 percent of urea, 15-25 percent of sodium nitrite, 10-15 percent of potassium sulphate, 22-30 percent of sodium metasilicate and 50-90 percent of carbon black. The environmentally friendly snow melting agent can be used for effectively solving the problems of the traditional snow melting agent used in China on corrosion to metal and cement concrete, damage to plant growth, and the like. The snow melting agent product does not contain sodium chloride, thereby reducing the influences and the damages to roads and environment of ordinary snow melting agents, and has the advantages of high snow melting speed, no corrosion, small feed dose, economy, environmental protection, and the like. Products after melting can be used for promoting the growth of plants, and compared with the traditional products, the snow melting agent has micro corrosion to the metal and the cement concrete and also has safety and reliability; the residual products after snow melting can be used for promoting the growth of the plants so as to realize reutilization; and the snow melting agent is easy to deliquesce, has certain effects of stabilizing soil and controlling dust and good flowability and is easy to scatter and mechanically spread.

Description

technical field [0001] The invention relates to a deicing agent, in particular to a novel environment-friendly deicing agent. Background technique [0002] my country's Northeast, Northwest, and North China regions have a cold winter climate and a lot of snowfall. When it snows or rains, the ground is prone to snow accumulation and freezing. At present, the commonly used and more effective snow removal methods are mainly mechanical snow removal and chemical snow melting. Mechanical snow removal has the characteristics of flexible maneuvering, fast speed, not limited by temperature, and wide application range, but it has disadvantages such as poor removal rate and easily damaged road surface. Chemical snow removal method can make up for the shortage of mechanical snow removal and is an effective anti-icing method. , Means of melting snow and melting ice. The deicing agents commonly used today are chlorine salt deicing agents, including sodium chloride, calcium chloride, magn...
