High molecular spraying dust suppressant prepared based on graft copolymerization method and preparation method

Abstract

The invention discloses a high molecular spraying dust suppressant prepared based on a graft copolymerization method and a preparation method. The high molecular spraying dust suppressant comprises the following components in percent by weight: sodium alginate, caprolactam, acrylic acid, an initiator, a crosslinking agent, an antifreezing agent and the balance of water. With the sodium alginate as a matrix, a graft copolymerization reaction is performed on the sodium alginate and the caprolactam to obtain a liquid substance which can form gel after water loss and can form a film after air drying, then a proper amount of acrylic acid is grafted to increase the toughness and the stickiness of the gel and the film, and a small amount of antifreezing agent is added to improve the antifreezing performance of the dust suppressant; after the environment-friendly dust suppressant is sprayed onto a coal mine production site, dust can be enwrapped in spraying droplets, so that dust diffusion can be effectively reduced; the dust-enwrapped droplets fall onto the ground surface to form the gel after water loss so as to cover dust on the ground and form a shell film after being dried so as to seal dust particles falling onto the ground surface, so that the dust falling efficiency is improved, and the dust diffusion is reduced.

Description

technical field [0001] The invention relates to a dust-removing agent for mine dust prevention, in particular to a spray dust-suppressing agent and a method for preparing polymer products based on a graft copolymerization method. Background technique [0002] With the continuous development of the coal industry and the continuous improvement of the mechanization level of coal mine production, the dust concentration generated in the coal mine production process has also increased. As we all know, when the dust concentration reaches a certain level, it may cause a dust explosion when encountering trigger conditions such as high temperature and fire source, causing great harm. Not only that, the dust produced in the coal mine production process also contains a large amount of respirable dust, which can enter the human body through breathing and deposit in the alveoli, causing serious and incurable harm to the human body, even life-threatening. According to the actual measureme...

Problems solved by technology

[0004] The existing chemical dust suppression technology is relatively simple, for example, compound surfactants are added to the spray dust suppression system to improve the ability to capture dust; sticky materials are used to cover the roadway wall to bond dust

The former focuses on the effect of dust removal, while the latter focuses on the suppression of dust. Although both are methods of dust control, their functions are relatively single, and the materials and reagents used may be expensive, and may even cause secondary pollution to the environment.
