Environment-friendly dust suppressant and preparation method thereof

Abstract

The invention discloses an environment-friendly dust suppressant and a preparation method thereof. The environment-friendly dust suppressant is prepared from the following raw materials in parts by weight: 8 to 12 parts of modified starch, 10 to 15 parts of carboxymethyl cellulose, 5 parts of xanthan gum, 5 parts of guar gum, 15 to 20 parts of potassium sulfate, 15 to 20 parts of sodium sulfate, 8to 12 parts of magnesium sulfate, 2 to 5 parts of hydroxypropyl methyl cellulose and 0.5 to 1 part of a surfactant. The prepared dust suppressant is wide in raw material source and simple in preparation process, can bond and solidify dust on the surface of bare soil, effectively inhibit the phenomenon of dust raising on the surface of bare soil, is naturally degradable, does not pollute the soil,contains various mineral elements which can be absorbed by the soil, and can increase the fertility and promote the growth of plants.

Description

technical field [0001] The invention relates to the technical field of field pile type dust suppressant, and more specifically relates to an environment-friendly dust suppressant and a preparation method thereof. Background technique [0002] With the continuous control of dust pollution, the traditional sprinkler dust suppression and dust suppression can not effectively reduce dust pollution, and the green net used for dust suppression is difficult to degrade naturally, resulting in new environmental pollution. Compared with traditional dust suppression methods, chemical dust suppression has a more significant effect and a longer duration of action, and will not cause secondary pollution to the environment. For example, the patent No. CN101824303A, the dust suppressant mixes acrylic acid and 30% sodium hydroxide to prepare a sodium acrylate solution, then mixes starch, initiator, and crosslinking agent after high-temperature gelatinization under nitrogen, and then dries and...

AI Technical Summary

Problems solved by technology

For example, the patent No. is CN101824303A. The dust suppressant mixes acrylic acid and 30% sodium hydroxide to prepare a sodium acrylate solution, and then mixes starch, initiator and crosslinking agent gelatinized at high temperature under nitrogen, and is dried and pulverized into shape. , the manufacturing process is complicated, the process is complicated and the operability is difficult, it is difficult to produce and apply on a large scale, and a strong alkali solution is used, the waste water is difficult to treat and resources are wasted

In addition, other current solutions include sprinkling water to suppress dust, but it is not only time-consuming and labor-intensive, but also the combination of water and floating dust is weak, and the actual effect is not good.
