Abstract
ABSTRACTIn the process of coal transportation and storage, a large amount of dust is inevitably generated, which seriously threatens the health of coal miners and causes the waste of resources. How to prevent and control the dust generated during coal transportation and storage is a key issue of coal mine occupational safety research. In this study, sodium alginate is reacted with 2‐acrylamide‐2‐methylpropanesulfonic acid, and the resulting intermediate is graft copolymerized with acrylic acid to prepare an environment friendly dust suppressant product suitable for coal transportation and storage. The microscopic reaction and structure of the product are analyzed by infrared spectroscopy, X‐ray photoelectron spectroscopy, thermogravimetric analysis, and scanning electron microscopy. The optimal synthesis conditions have been obtained by taking the strength of the coking coal as the single factor experiment evaluation index. Through the research on the related properties of the dust suppressant, it is found that this dust suppressant has excellent performance and an obvious dust suppression effect. © 2019 Wiley Periodicals, Inc.
