Problems solved by technology

While making these progresses, we should also see some shortcomings, such as: halide dust suppressants are corrosive to metals; inorganic dust suppressants will increase ash content and easily lead to salinization of soil ; The polymer water-absorbent resin is easy to cause soil compaction, which is not conducive to the growth of plants; some polymer dust suppressants are not degradable, which will cause secondary pollution to the environment

Embodiment 1

[0023] Get 0.2% of natural latex, 0.2% of wood fiber, 0.5% of glycerol, and 0.1% of sodium dodecylbenzenesulfonate by weight percentage; make up to 100% with water. At normal temperature and pressure, add natural latex, wood fiber, glycerol, and sodium dodecylbenzenesulfonate into the mixer according to the above ratio and mix them thoroughly, and slowly add the mixed materials into the water Stir fully to make the dust suppressant of the present invention.

Embodiment 2

[0025] Take 0.3% of natural latex, 0.1% of wood fiber, 0.5% of glycerol, and 0.1% of sodium dodecylbenzenesulfonate by mass percentage, and make up to 100% with water. At normal temperature and pressure, add natural latex, wood fiber, glycerol, and sodium dodecylbenzenesulfonate into the mixer according to the above ratio and mix them thoroughly, and slowly add the mixed materials into the water Stir fully to make the dust suppressant of the present invention.

Embodiment 3

[0027] Take 0.3% of natural latex, 0.05% of wood fiber, 0.3% of glycerol, and 0.15% of sodium dodecylbenzenesulfonate by weight percentage, and make up to 100% with water. At normal temperature and pressure, add natural latex, wood fiber, glycerol, and sodium dodecylbenzenesulfonate into the mixer according to the above ratio and mix them thoroughly, and slowly add the mixed materials into the water Stir fully to make the dust suppressant of the present invention.

Abstract

The invention discloses an environmentally friendly biodegradable dust suppressant and a preparation method thereof. The preparation method comprises adding natural latex, natural plant fibers, glycerol and a surfactant into a mixer, stirring fully to mix them well, adding slowly the mixture into water, and stirring fully to obtain the environmentally friendly degradable dust suppressant. The environmentally friendly biodegradable dust suppressant has the functions of film forming, wetting and coagulation, and characteristics of no ash, no toxicity, no corrosivity, no secondary pollution, favorable biodegradability, simple preparation process, and low cost. After being sprayed on the surface of a material, the environmentally friendly biodegradable dust suppressant can form a continuous, intact, strong and ductile shell film to confine dust in a shell, and thus air pollution is avoided and material loss is reduced. The environmentally friendly biodegradable dust suppressant can resist the effects of wind power, rainwater and a general external force, is suitable for dust control of road surfaces, coal piles, ore piles, building sites, heat-engine plants, steel mills and coal transportation by trains, and has broad social and economic benefits.

Description

technical field [0001] The invention relates to a dust suppressant, in particular to an environment-friendly degradable dust suppressant and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, dust pollution has become an important factor affecting the environment in our country, which has brought huge negative effects on both economic development and environmental governance. For example, the dust pollution caused by the transportation of coal and mineral bulk materials not only affects the surrounding environment of the railway, but also brings huge economic losses. It is estimated that 1-2% of coal is lost in vain due to dust during transportation. For a special coal line with an annual transportation volume of 100 million tons, about 1-2 million tons of coal will be lost every year. In our country's special ports for coal transportation, the annual loss of coal and mineral powder due to dust is also about 1%. ...
