preparation example Construction

[0093] According to a second aspect of the present invention, a kind of preparation method of dust suppressant is provided, comprising the following steps:

[0094] The dust suppressant is obtained by mixing the crusting agent, the moisturizing agent, the surfactant water and optional auxiliary materials.

[0095] 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.

[0096] Preferably, the preparation method of dust suppressant comprises the following steps:

[0097] (a) adding a humectant and a surfactant to water, and mixing to a homogeneous phase to obtain a mixed solution;

[0098] (b) Add crusting agent and optional auxiliary materials in batches to the mixed solution, and mix well to obtain dust suppressant;

[0099] Preferably, step (a) mixing and stirring speed is 30~50rad / min;

[0100] After step (a) is ad...

Embodiment 1

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: 30-70% of crusting agent, 0.5-5% of moisturizing agent, 0.5-10% of surfactant, 0-2% of auxiliary materials and the balance of water. The crusting agent is prepared from natural latex; the surfactant is prepared from a polyoxyethylene type nonionic surfactant. The dust suppressant provided by the invention is environmentally friendly andcan adhere soil particles; after being dried, the soil surface sprayed with the dust suppressant has an obvious crusting phenomenon; the dust suppressant is high in dust suppression efficiency, has higher moisturizing rate and excellent film forming property, and also has the characteristics of being low in transportation cost, convenient and fast to use, and the like. The preparation method andthe 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 suitablefor industrial production. When in use, the dust suppressant can be 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] Infrastructure construction has been the focus of development for many years, improving people's livelihood and improving the transportation system. The increasingly perfect infrastructure has effectively improved the living standards of the people, but the dust from a large number of construction sites and bare land, as one of the sources of suspended particulate matter, has also become a problem for air pollution prevention and control. The current treatment measures are mainly to cover the bare land with dust-proof nets, spray with fog cannons, and use inorganic salt dust suppressants. [0003] Since the holes of the dust-proof net are much larger than the dust particles, the dust suppression effect is not obvious after being covered with thatch. Moreover, the q...
