Embodiment 1

[0022] Weigh 70 grams of magnesium nitrate, 10 grams of sodium sulfate, 5 grams of sodium acetate, and 15 grams of calcium carbonate particles. After fully mixing magnesium nitrate, sodium acetate, and sodium sulfate, pass through a 40-mesh sieve after being pulverized by a pulverizer, and then mix with anti-slip agent After entering the mixer and fully mixing, put it into a 25 kg plastic film bag and seal it immediately, and add a woven bag to seal it, which is the environmental protection deicing agent of the present invention.

Embodiment 2

[0024] Take by weighing 70 grams of magnesium nitrate, 15 grams of urea, 5 grams of sodium acetate, 5 grams of sodium formate, and 5 grams of calcium carbonate particles. After fully mixing magnesium nitrate, urea, sodium acetate, and sodium formate, pass through a 40-mesh sieve after pulverizing by a pulverizer. Then enter the mixer with the anti-skid agent and fully mix it, then pack it into a 25 kg plastic film bag and seal it immediately, and add a woven bag to seal it, which is the environmental protection deicing agent of the present invention.

Embodiment 3

[0026] Weigh 70 grams of magnesium nitrate, 10 grams of sodium acetate, 10 grams of urea, 5 grams of potassium acetate, and 5 grams of calcium carbonate particles. After fully mixing magnesium nitrate, urea, sodium acetate, and potassium acetate, pass through a 40 mesh after pulverizing Sieve, then enter the mixer with the anti-skid agent and fully mix it, then pack it into a 25 kg plastic film bag and seal it immediately, and add a woven bag to seal it, which is the environmental protection deicing agent of the present invention.

Abstract

The invention relates to an environment protection snow-dissolved agent, which is composed of magnesium nitrate and sodium acetate. Each reactant is fully mixed and smashed according to ratio; then, the reactant is fully mixed with slip proofing agent to be filled into a plastic film for sealing; and a woven bag is arranged outside for sealing, so that the environment protection snow-dissolved agent of the invention is obtained. The snow-dissolved agent overcomes the damages in the traditional snow-dissolved agent, such as corrosion to roads and bridges and influence on farmland crops and green plants on two sides of roads and the like. The invention has fast snow dissolving speed, favourable effect, low cost and wide using temperature range, and the applicable temperature range is minus 5 DEG C-minus 35 DEG C, so the invention has favourable promotion and application prospect.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly deicing agent and a preparation method thereof. Background technique [0002] Snowfall in winter has caused great inconvenience to the transportation systems of our country and other countries in the world, resulting in road blockages, increased traffic accidents, and even being forced to close highways when the snowfall is heavy, seriously restricting the normal operation of the transportation system. Snow removal after snow has become the key to ensure the normal operation of the transportation system. The current snow removal methods mainly include artificial snow removal, mechanical snow removal and deicing agent snow removal. However, manual and mechanical snow removal are less efficient and consume more manpower and material resources. In order to remove snow conveniently, quickly and efficiently, humans began to use deicing agents to remove snow. At present, the...
