Green and high-efficiency mine pavement dust suppressant and preparation method thereof

Abstract

The invention provides a green and high-efficiency mine pavement dust suppressant, which comprises the following components in mass percent: 15% to 30% of calcium magnesium lactate, 0.1% to 0.3% of calcium lignosulfonate grafted polyacrylic acid / acrylamide compound %, cardanyl betaine 0.01% to 0.15%, glycerin 0.2% to 1%, and the balance is deionized water; the preparation method is: (1) graft polyacrylic acid / propylene with deionized water and calcium lignosulfonate Add the amide complex into the mixing tank, stir until it is evenly mixed, and obtain mixture A; (2) add the above-mentioned calcium magnesium lactate, cardanyl betaine and glycerin to the mixture A, stir until completely dissolved, and let it stand for 60 minutes, That is, a green and high-efficiency mine pavement dust suppressant can be obtained. The raw materials used in the dust suppressant provided by the invention are all biomass derivatives, are biodegradable, are a color-friendly dust suppressant, and have a dust suppression efficiency of up to 98% and an effective dust suppression time of more than 10 days.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a green and high-efficiency mine pavement dust suppressant and a preparation method thereof. Background technique [0002] Open-pit mine stope roads are mostly composed of gravel and sand. During the open-pit mining process, due to the use of large-scale stripping, mining, loading and unloading and transportation equipment, a large amount of fine-grained dust accumulates on the road surface, and the interaction between these dust particles is small. , A large amount of dust will be raised when the natural wind or the car is running, especially when the large transport vehicle is driving on the road surface of the stope. The dust on the road surface not only causes dust pollution in the whole mine, deteriorates the air quality of the stope, and induces pneumoconiosis, but also high concentration of dust will affect the transportation capacity of...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned deficiencies existing in the prior art, one of the purposes of the present invention is to provide a green and efficient mine road surface dust suppressant, in order to solve the problem of poor wettability and short dust suppression time of the existing open-pit mine transportation road dust suppressant , the serious problem of soil pollution; the second object of the present invention is to provide a preparation method of a green and efficient mine pavement dust suppressant
