Embodiment 1

[0021] Composite chemical dust suppressant of the present invention is made up of the raw material of following percentage by weight:

[0022] Polyethylene glycol 40005%, sodium sulfate 1%, polyvinyl acetate 2%, gelatin 11%, starch 70%, sodium polyacrylate 1%.

[0023] The concrete steps of the preparation method of composite chemical dust suppressant of the present invention are as follows:

[0024] (1) take raw materials by proportioning;

[0025] (2) Freeze-dry polyethylene glycol 4000 at ultra-low temperature from -40°C to -30°C, and crush it with a powerful pulverizer. Start for 10 minutes, rest for 5 minutes, repeat 3 times.

[0026] (3) All the raw materials weighed are added in the pulverizing mixer, the machine is turned on and pulverized for 10 minutes, then intermittently for 5 minutes, and so repeated 3 times to obtain the composite chemical dust suppressant of the present invention.

Abstract

The invention discloses a composite chemical dust suppressant and a preparation method thereof. The composite chemical dust suppressant of the present invention is composed of the following raw materials in percentage by weight: polyethylene glycol 40005%-50%, sodium sulfate 1%-20%, polyvinyl acetate 2%-45%, gelatin 5%- 55%, starch 15%-70%, sodium polyacrylate 1%-10%. The composite chemical dust suppressant of the present invention has the advantages of high economical applicability, high practical applicability, environmental friendliness and good dust suppression effect. The raw materials used in the composite chemical dust suppressant of the present invention are low in cost and environmentally friendly. Prevent dust pollution and protect the environment, and the raw materials used are non-toxic and harmless to the environment.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, in particular to a composite chemical dust suppressant and a preparation method thereof. Background technique [0002] Dust can be divided into two categories according to particle size: the one with large diameter is called falling dust, which is heavy and easy to settle, and the one with small diameter is called floating dust, which floats in the air for a long time in the form of aerosol and cannot be seen by naked eyes. Dust contains a variety of heavy metals, and the floating dust can absorb various toxic substances, some of which are carcinogens. Flying dust adsorbed with toxic substances floats everywhere, seriously polluting the environment on which we live. [0003] The dust suppressant is composed of new multifunctional polymers. The degree of cross-linking between polymer molecules will form a network structure, and there are various ionic groups between the molecules, whic...
