preparation example Construction

[0097] According to a second aspect of the present invention, a kind of preparation method of dust suppressant is provided, comprising the following steps:

[0098] The dust suppression agent is obtained by mixing the crusting agent, auxiliary dispersant, water and optional auxiliary materials.

[0099] The preparation method of the dust suppressant of the present invention is simple and easy, easy to operate and control, has low energy consumption and low cost, and is very suitable for industrialized production.

[0100] Preferably, the preparation method of dust suppressant comprises the following steps:

[0101] (a) adding the formula amount of crusting agent into part of water at 50-70°C in batches to obtain solution A;

[0102] (b) adding the auxiliary dispersing agent of formula quantity into remaining water in batches to obtain solution B;

[0103] (c) solution A and solution B are mixed in batches, and optional auxiliary materials are added and mixed to obtain a dust...

Embodiment 1

[0131] A dust suppressant, by weight percentage, comprising:

[0132] Sodium alginate 1.5%, Brij35 0.3%, pH regulator hydrochloric acid 0.05%, defoamer (DF568) 0.05%, water balance;

[0133] The preparation method of dust suppressant comprises the following steps:

Abstract

The invention discloses a dust suppressant as well as a preparation method, a using method and application thereof, and relates to the technical field of dust suppressants. The dust suppressant is mainly prepared from the following components by weight percent: 0.15-6% of crusting agent, 0.05-5% of co-dispersant, 0-2% of auxiliary materials and the balance of water. The crusting agent is preparedfrom a natural high molecular polymer; the co-dispersant is prepared from a polyoxyethylene type nonionic surfactant. The dust suppressant provided by the invention is environmentally friendly, high in dust suppression efficiency and long in duration time, has higher moisturizing rate and excellent film forming property, has a sustainable dust suppressing effect after the road surface is dry, andalso has the characteristics of being low in transportation cost, convenient and fast to use, and the like. The preparation method and the using method of the dust suppressant are simple and easy to implement; the preparation method is convenient to operate and control, and low in energy consumption and cost, thus being very suitable for industrial production. When in use, the dust suppressant canbe sprayed after being diluted with water, thus being convenient to use and good in effect.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, in particular to a dust suppressant and its preparation method, use method and application. Background technique [0002] In recent years, my country's air quality has faced severe challenges, and relevant national functional departments have also introduced measures to actively respond. PM 2.5 and PM 10 It is the main particle component of haze weather in recent years, and road dust is one of the sources of particle pollution. The country pays more and more attention to environmental protection, and intensifies efforts to prevent and control air pollution and smog. As one of the sources of air pollution, road dust is mainly controlled by street sweeping and dust suppression by sprinklers. By spraying the road surface, increasing the humidity of the road surface to suppress road dust, or adding inorganic salt dust suppressant to the sprinkler, so as to increase the wet time of the r...
