Abstract

The invention belongs to the technical field of dust settling agents and preparation methods thereof and in particular relates to a degradable dust settling agent and a preparation method thereof, solving the technical problem that existing dust settling agents have narrow ranges of application and poor dust settling effects, are high in use cost and pollute the environment. The degradable dust settling agent is prepared from 10-40 parts of fatty alcohol-ethylene oxide-propylene oxide block copolymer, 40-100 parts of surfactant, 5-20 parts of macromolecular substance, 10-50 parts of solvent, 3-20 parts of anti-freezing agent and 0-5 parts of metal corrosion inhibitor. The dust settling agent has the advantages of wide range of application, good dust settling effect, low use cost and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of dust suppressant and its preparation method, and in particular relates to a degradable dust suppressant and its preparation method. Background technique [0002] With the continuous development of the economy, people's demand for the control of environmental pollution, especially air pollution, is increasing. In the coal mine industry, with the improvement of the degree of mechanization, the hazard of underground dust has become an increasingly prominent problem. Coal mine dust not only affects mine production safety, but also threatens the health of workers and pollutes the environment. In recent years, various dust suppression methods have emerged as the times require and continue to develop. Among them, the use of dust suppression agent as one of the new means of dust prevention is quite popular and has been applied by more and more coal mines. The existing dust-reducing agent has the technical prob...
