Problems solved by technology

The traditional watering method, in the hot summer, especially in the north, the water evaporates quickly, and the effect will be lost after the water evaporates, requiring frequent watering, which will cause a huge waste of water resources and expense
Some existing dust suppressants cannot meet the actual needs, such as glycerol, which can suppress slight floating dust to a certain extent, and the dust-fixing effect is relatively small for soil piles with a large amount of dust
Some use styrene substances, which have a significant dust suppression effect, but are more environmentally toxic

Embodiment 1

[0020] A dust suppressant for suppressing dust suspension, the components and weight of the dust suppressant are: water 85Kg; polyvinyl alcohol 8.5Kg; polysaccharide 3.5Kg; surfactant 2.5Kg; sodium benzoate 0.5Kg. Wherein the water is tap water, the polysaccharide is carboxymethyl cellulose, and the surfactant is sodium dodecylsulfonate.

[0021] A preparation method of a dust suppressant for suppressing dust suspension. The method is to first add water to a reaction kettle according to the ratio of parts by weight, heat to 70°C, and then slowly add polyvinyl alcohol, polysaccharide, and surfactant respectively. 1. Sodium benzoate, stirred and heated until completely dissolved, mixed evenly, and after 20 minutes of heat preservation, the finished product of the dust suppressant for suppressing the suspension of dust was obtained. The finished product is diluted 10 times and sprayed on the surface of the mound of a construction site, the spraying amount is 2.0kg / m2, after 8 hou...

Embodiment 2

[0023] A dust suppressant for suppressing dust suspension, the components and weight of the dust suppressant are: water 50Kg; polyvinyl alcohol 2Kg; polysaccharide 1Kg; surfactant 0.5Kg; sodium benzoate 0.1Kg. Wherein the water is tap water, the polysaccharide is sodium carboxyethyl cellulose, and the surfactant is sodium tetradecylbenzenesulfonate.

[0024] A preparation method of a dust suppressant for suppressing dust suspension. The method is to first add water to a reaction kettle according to the ratio of parts by weight, heat it to 60°C, and then slowly add polyvinyl alcohol, polysaccharide, and surfactant respectively. 1. Sodium benzoate, stirred and heated until completely dissolved, mixed uniformly, and after 15 minutes of heat preservation, the finished product of the dust suppressant for suppressing the suspension of dust was obtained. The finished product is diluted 10 times and sprayed on the road surface of a construction site. The spraying amount is 1.2kg / m2. C...

Embodiment 3

Abstract

The present invention relates to a dust inhibition agent for inhibiting dust suspension. The dust inhibition agent comprises, by weight, 50-90 parts of water, 2-30 parts of polyvinyl alcohol, 1-20 parts of polysaccharide, 0.5-5 parts of a surfactant, and 0.1-3 parts of sodium benzoate, wherein the dust inhibition agent has characteristics of no toxicity, no harm, biodegradability and no secondary pollution. During a use process, the diluted dust inhibition agent is sprayed on sand soil heap, ash heap, road surface and the like, provides effects of wetting, adhesion, condensation, moisture absorption, dust resistance, etching resistance and erosion resistance through capturing, absorbing and aggregating dust micro-particles, and forms a layer of an adhesive film with a network structure on the surface so as to effectively fix dust and form a protection film on the surface of the material, such that the dust is fixed, dust re-suspension is inhibited, material loss can be effectively reduced, dust pollution is reduced, the environment is protected, and health of workers and the surrounding population are protected.

Description

technical field [0001] The invention belongs to the field of dust suppressants, in particular to a dust suppressant for suppressing dust suspension and a preparation method thereof. Background technique [0002] my country's society and economy are in a period of comprehensive development, and the dust pollution caused by construction, stockyard accumulation, material transportation, road dust, power plant ash yard, mineral stacking, and coal transportation in economic construction activities is becoming more and more serious. At present, suspended particulate matter with aerodynamic diameter less than 10 μm has become the main pollutant in my country's urban inhalable particulate matter, and these are closely related to dust. [0003] At present, dust-suppressing cloth is widely used for the accumulation of earthwork and sand in the construction process, which is neither environmentally friendly nor economical, with serious waste and mediocre effect. There are many simple ...
