Embodiment 1

[0059] A highly efficient and environmentally friendly dust suppressant:

[0060] Feed according to the following formula: by weight,

[0061]Polyvinyl alcohol 1750 5%,

[0062] Sodium silicate 0.1%,

[0063] Glycerol 20%,

[0064] Sodium dodecylbenzenesulfonate 0.02%,

[0065] Sodium dehydroacetate 0.01%,

[0066] water balance.

[0067] Preparation Process:

[0068] (1) Preparation of solution A: Add polyvinyl alcohol and deionized water into the reactor, heat at constant temperature (90-95°C) until completely dissolved;

[0069] (2) Preparation of solution B: add the remaining raw materials and remaining deionized water into the container, and stir evenly;

[0070] (3) Slowly add solution B to solution A, and stir evenly to obtain a milky white liquid, which is the road dust suppressant solution.

Embodiment 2

Abstract

The invention provides a high-efficiency environmental-friendly dust suppressant as well as a preparation method and application thereof. The high-efficiency environmental-friendly dust suppressant disclosed by the invention solves the problems that the conventional product is single in function, secondary pollution is introduced and the like, has wide application and is particularly applicable to roads with less dust particles, for example, the dust suppressant is used for capturing and adsorbing TSP (Total Suspended Particulates), PM10, PM2.5 and nitric oxides. The high-efficiency environmental-friendly dust suppressant disclosed by the invention is mainly prepared by mixing the following components by weight: 0.1-10% of polyvinyl alcohol, 0.1-5% of sodium silicate, 10-50% of glycerin, 0.01-5% of a surfactant, 0-5% of a preservative, and the balance of water.

Description

technical field [0001] The invention relates to the field of sanitation, in particular to a high-efficiency and environment-friendly dust suppressant and its preparation method and application. Background technique [0002] Particulate matter pollution has a wide range of influences on urban air quality in my country, and it is the primary factor of air pollution in most cities. The general prevention and control measures for open dust sources at home and abroad mainly include sprinkling water for dust suppression, covering with thatch for dust suppression, setting up windshield walls for dust suppression, building closed structures, and chemical dust suppression. Sprinkling water to suppress dust not only causes a lot of waste of water resources, but also due to the high temperature in summer and fast evaporation in northern China (generally, one spraying can only be kept for about 10 minutes), while the temperature in winter is low and easy to freeze, so its practical appl...
