Embodiment 1

[0057] A highly efficient and environmentally friendly dust suppressant:

[0058] Feed according to the following formula: by weight,

[0059] Anionic water-based polyurethane (50% solid content) 0.3%,

[0060] Sodium carboxymethylcellulose 0.2%,

[0061] Sodium Alginate 0.1%,

[0062] Polyvinyl alcohol 1750 0.12%,

[0063] Sodium silicate 0.1%,

[0064] Glycerol 20%,

[0065] Sodium dodecylbenzenesulfonate 0.02%,

[0066] water balance.

[0067] making 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 2-3

[0072] The difference with Example 1 is only that the glycerol consumption is different, which are respectively 40%, 50%.

Embodiment 4

[0074] The difference from Example 1 is only that water-based polyurethane is replaced by styrene-butadiene latex.

Abstract

The invention provides an efficient environment-friendly dust suppressant as well as a preparation method and application thereof. The efficient environment-friendly dust suppressant can solve the problems of single function, possibility of causing secondary pollution, and the like, of the present product, is widely applied and is especially suitable for roads with small dust particles, such as, capturing and absorbing for total suspended particulates, PM10, PM2.5 and nitric oxide. The efficient environment-friendly dust suppressant provided by the invention is prepared by mixing the following components by weight percent: 0.1-7% of latex, 0.1-6% of modified starch/modified cellulose, 0.1-5% of sodium alga acid, 0.1-8% of polyvinyl alcohol, 0.1-8% of sodium silicate, 10-60% of glycerol, 0.01-5% of surfactant 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...
