Abstract

The invention discloses a novel high-molecular environmentally-friendly dust-suppressing agent. The novel high-molecular environmentally-friendly dust-suppressing agent comprises the following raw materials, in parts by weight: 10-20 parts of an initiator, 5-10 parts of a crosslinking agent, 4-8 parts of a pH buffering agent, 10-15 parts of gellan gum, 10-20 parts of sodium carboxymethylcellulose,12-16 parts of sodium tetraborate, 1-5 parts of a surfactant, 60-80 parts of starch and 150-200 parts of deionized water. The preparation method comprises the following steps: adding the deionized water and the starch into a reaction kettle according to a ratio of 2:1, performing gelatinization, performing cooling, adding 50-200 mL of a monomer solution, adding the initiator, the crosslinking agent, the pH buffering agent, the gellan gum, the sodium carboxymethylcellulose, the sodium tetraborate and the surfactant, performing heating under stirring under anaerobic conditions, and performing aconstant-temperature reaction for 2-3 h at 60-90 DEG C to obtain the novel high-molecular environmentally-friendly dust-suppressing agent. The novel high-molecular environmentally-friendly dust-suppressing agent provided by the invention has a simple manufacturing process, is easy to operate, effectively reduces dust flying, greatly reduces an atmospheric dust concentration in a dust suppressionsite, and has significant social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel polymer environmental protection dust inhibitor. Background technique [0002] With the development of industry and the improvement of people's living standards, environmental protection and effective use of resources have become the focus of common attention of all countries in the world. People pay more and more attention to preventing dust pollution caused by construction, mining, workshop operation, etc. Although the traditional sprinkling and dust prevention is simple, this method not only causes a great waste of water resources, but also hardly achieves the effect of dust prevention because the water evaporates too fast. Therefore, there is an urgent need for those skilled in the art to develop a novel polymer environmental protection dust inhibitor. Contents of the invention [0003] The object of the present invention is to provide a novel pol...
