Embodiment 1

[0015] Dissolve 3g of carboxymethyl starch in 100ml of water and stir evenly. After it dissolves completely, add 1g of sodium polyacrylate, 1g of urea, and 0.5g of sodium dodecylbenzene sulfonate in sequence, and stir until it dissolves evenly to obtain the road inhibitor. Dust finished product.

[0016] The content of each component in the above-mentioned dust suppressant solution is: carboxymethyl starch 2.8%, sodium polyacrylate 0.95%, urea 0.95%, sodium dodecylbenzenesulfonate 0.47%. Moisture absorption performance, suitable for muddy road sites.

Embodiment 2

[0018] Dissolve 1.5g of carboxymethyl cellulose in 100ml of water, stir evenly, add 0.8g of sodium polyacrylate, 0.6g of urea, and 0.3g of sodium dodecylbenzenesulfonate in turn after it dissolves completely, and stir until it dissolves evenly. The finished road dust suppressant can be obtained.

[0019] The content of each component in the above-mentioned dust suppressant solution is: 1.5% of carboxymethyl cellulose, 0.78% of sodium polyacrylate, 0.58% of urea, and 0.29% of sodium dodecylbenzenesulfonate. The finished dust suppressant has a good Wetting and hygroscopic properties, suitable for streets and cement roads.

Embodiment 3

[0021] Take 1.2g of carboxymethyl starch dissolved in 100ml of water, stir evenly, after it is completely dissolved, add 0.6g of sodium polyacrylate, 0.6g of urea, 0.3g of sodium dodecylbenzenesulfonate, and stir until it dissolves evenly Obtain the finished road dust suppressant.

[0022] The content of each component in the above dust suppressant solution is: 1.2% carboxymethyl starch, 0.58% sodium polyacrylate, 0.58% urea, 0.29% sodium dodecylbenzenesulfonate. Moisture absorption performance, suitable for indoor cement floor and cladding, etc.

[0023] The road surface dust suppressant of the present invention is a liquid dust suppressant with strong anti-compressive function integrating comprehensive properties such as coagulation, penetration, moisture absorption and water retention. The dust suppressant is composed of three main parts: coagulation, moisture absorption and water retention. One is the coagulation factor. It is made of water-soluble polymer materials to ...

Abstract

The present invention discloses a road surface dust suppressant and a preparation method thereof, wherein the road surface dust suppressant comprises 1-3% of a water-soluble macromolecule polymer, 0.5-1.5% of sodium polyacrylate, 0.5-1% of urea, 0.2-0.5% of an anionic surfactant, and the balance of water. According to the present invention, the road surface dust suppressant can be applied in road dust suppression, earth work dust emission treatment in mine exploitation, mine field road transportation and municipal construction, and other fields so as to effectively solve the problem of dust pollution, ensure transportation safety and health safety of motorcyclists and staffs around, reduce the maintenance cost of the transportation equipment, increase the service life of the equipment, and especially solve the problem of rolling dust emission of the heavy duty transportation tool.

Description

technical field [0001] The invention relates to a road surface dust suppressant and a preparation method thereof. Background technique [0002] Dust pollution is one of the world's environmental hazards. For half a century, people have been working on the prevention and control technology of dust pollution. In production and storage sites such as ports, power plants, cement plants, and coal storage yards, as well as during railway and road transportation, a large amount of dust is often generated, which not only directly threatens the safety of production, but also causes great pollution to the surrounding environment. Among them, during the transportation of goods at docks and mines, the dust generated by heavy trucks during road operation has become the main source of dust pollution. At present, in addition to sprinkling dust (including sprinkling, spraying, ultrasonic and electrostatic water), the common dust suppression techniques at home and abroad also include sprayin...
