Abstract

The invention discloses a coal dust inhibitor and a preparation method thereof. The coal dust inhibitor comprises an organic binding agent, a penetrating agent, a humectant, a de-foaming agent and water, wherein the organic binding agent comprises polyacrylamide and polyvinyl alcohol; the humectant comprises hydroxypropyl methyl cellulose, sodium carboxymethylcellulose and glycerol. The preparation method of the coal dust inhibitor comprises the following steps: mixing components in following (1) or (2) and uniformly mixing: (1) the organic binding agent, the penetrating agent, the humectant, the de-foaming agent and water; (2) the organic binding agent, the penetrating agent, the humectant, the de-foaming agent, an pH adjusting value, color modulation emulsion, an auxiliary agent and water. The coal dust inhibitor has a high speed of forming a cured protection layer and has proper mechanical strength and water resistance; the preparation method is simple and has the characteristic that needed production equipment is little. The coal dust inhibitor can be used for dust inhibition of coal transportation, storage, construction sites and the like.

Description

Technical field [0001] The invention relates to a coal dust inhibitor and a preparation method thereof. Background technique [0002] The total coal reserves in my country are more than 1 trillion tons, of which the three provinces (regions) of Shanxi, Shaanxi and Mongolia account for more than 60%. The overall pattern is that the north is rich and the south is poor, and the west is more and the east is less. While coal consumption is mainly in the eastern region, the dislocation of coal production and consumption in my country has formed a consumption pattern of coal transportation "from north to south and west to east". The speed of railways has been increased several times, highways have increased, and the speed of transportation has been greatly accelerated. The degree of dust thrown during transportation has increased. The coal loss of existing transportation methods has reached 0.8% to 1%. In the process of coal transportation, the scattered coal powder pollutes the enviro...
