Moisturizing dust suppressant for road dust and preparation method thereof

Abstract

The invention belongs to the technical field of road dust control, and relates to a moisturizing dust suppressant for road dust and a preparation method thereof. The moisturizing dust suppressant for road dust of the present invention is prepared from the following raw materials in mass percent: 3.6% to 8% of a mixture of acetyl tributyl citrate, aqueous stearic acid emulsion and soluble starch, and 0.1% of a binder. ~10%, humectant 0.1~5%, surfactant 0.1~1%, balance is water. The road dust suppressant provided by the invention is sprayed on the road to form a layer of "soft film" with strong moisture retention, which can effectively condense the small particles on the ground surface into large particles, so as to effectively prevent the secondary raising of dust, thereby To achieve the effect of dust suppression.

Description

technical field

[0001] The invention belongs to the technical field of road dust control, and relates to a moisturizing dust suppressant for road dust and a preparation method thereof. Background technique

[0002] A large amount of dust accumulates on roads such as urban roads and expressways, and the road dust continues to diffuse into the atmosphere during the driving process of vehicles, seriously polluting the surrounding environment and affecting the normal work and life of surrounding residents. Dynamic dust suppression has always been a difficult point in dust control. Most of the existing dust suppressant products and technologies use calcium salts, halides and alcohols as main components.

[0003] Most of the current road dust suppressants have the following problems:

[0004] 1. Dust suppressants generally have weak moisturizing power and poor lasting power;

[0005] 2. The application of road dust suppressant reduces the frictional resistance of the road surfa...
