Embodiment 1

[0022] Take 10g of starch, 1g of iodine, and 2g of potassium iodide, add 987g of water, stir thoroughly, and mix evenly. The obtained dark blue mixed solution is a liquid snow-melting and deicing agent. The liquid snow-melting and de-icing agent can be prepared and used immediately, using the existing urban road sprinkler, or artificially spraying on the ice and snow road.

Embodiment 2

[0024] Mix starch, iodine, and potassium iodide at a mass ratio of 10:1:2, grind and pulverize, mix thoroughly, and sieve through 80 meshes. The obtained powder is a solid snow-melting and deicing agent. Apply the existing urban pavement chlorine salt deicing agent spraying method to the ice and snow pavement.

Embodiment 3

[0026] Comparison of ice melting rate between liquid and solid snow melting and deicing agents:

[0027] Take the same petri dish and put the same amount of ice cubes; take 10g of starch, 1g of iodine, and 2g of potassium iodide, and add 987g of water; take 20g of starch, 1g of iodine, and 2g of potassium iodide, and add 977g of water; take 30g of starch, 1g of iodine, and 2g of potassium iodide, Add 967g of water; prepare 3 concentrations of liquid snow-melting and ice-melting agents, and spray 10mL on ice cubes 1, 2, and 3 respectively;

[0028] According to the mass ratio of 10:1:2, 20:1:2, 30:1:2, solid-state snow-melting and deicing agents with three concentrations of starch, iodine and potassium iodide were prepared, and 0.13g, 0.23g and 0.33g were evenly spread on the ice Blocks 4, 5, 6; take the same ice blocks 7, 8, 9 as a reference. Put 9 ice cubes under normal sunlight at the same time, and quickly and accurately weigh the mass of liquid water in the petri dish aft...

Abstract

The invention provides an environment-friendly snow-melting and ice-melting agent and a preparation method thereof, which belong to the technical field of snow-melting agents. The raw materials of the snow-melting and ice-melting agent include starch, iodine and potassium iodide with a mass ratio of 10-30:1:2-5. The snow-melting and ice-melting agent of the present invention belongs to the non-chlorine salt type snow-melting and ice-melting agent, which is not corrosive to concrete, steel bars, etc., does not pollute water sources, and is less harmful to road surfaces, bridges, and automobiles. The snow-melting and ice-melting agent of the invention has fast melting speed of ice and snow, no residue, simple preparation method, easy-to-obtain raw materials, low cost, is suitable for factory batch production, is convenient to transport, and is safe to use and store. The invention solves the problems of corrosion and damage of the existing chlorine salt type snow-melting and deicing agent residues to road and bridge reinforcement facilities and pollution of biological environment on both sides of the road.

Description

technical field [0001] The invention relates to a snow-melting agent, in particular to an environment-friendly snow-melting and ice-melting agent and a preparation method thereof. Background technique [0002] Melting snow and ice on roads has great social, economic and national defense significance, and is also one of the worldwide problems. Melting ice and snow by spreading snow-melting and deicing agents is the most common method to reduce the freezing point of snow water and prevent roads from icing. At present, there are many kinds of snow-melting and de-icing agents, such as the traditional chloride-salt-type snow-melting and de-icing agents, and the sugar juice-type snow-melting and de-icing agents used in Canada and other countries. The traditional chlorine-salt snow-melting and de-icing agents are the most commonly used, but they will form a local strong electrolyte solution while melting snow and ice, causing infrastructure corrosion, destroying the integrity of t...
