Abstract

The invention relates to the technical field of dust suppression, and particularly relates a multi-functional biological high-efficiency dust suppressant, and a preparation process and an application method thereof. The multi-functional biological high-efficiency dust suppressant comprises the following components in percentage by weight: 5-10 percent of water-soluble polyvinyl alcohol, 5-10 percent of fatty alcohol-polyoxyethylene ether, 10-15 percent of dipropylene glycol mono butyl ether, 0.1-0.2 percent of dowcorning organic silicon 120A, 0.1-0.2 percent of dodecyl dimethyl benzyl ammonium chloride and 1-5 percent of diethylene glycol butyl ether. The dust suppressant is formed by composition of multi-functional high-molecular polymer, crosslinking degree molecules in the polymer form a mesh structure, various ion groups exist among molecules, a relatively strong affinity is generated among ions due to large electric density, particle dust can be quickly captured and firmly adsorbed, and the multi-functional biological high-efficiency dust suppressant has strong dust suppressing and dust proofing effects.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, in particular to a multifunctional ecological high-efficiency dust suppressant and its preparation process and application method. Background technique [0002] With the rapid development of my country's economy, environmental pollution has become more and more serious, among which dust pollution is one of the main factors leading to environmental pollution. During transportation, a large amount of dust is often produced, which not only directly threatens production safety, but also causes great pollution to the environment. [0003] Since January 2013, Beijing Xizhimen North, South Third Ring Road, Olympic Sports Center and other monitoring points have monitored the real-time concentration of PM2.5 to exceed 900 μg / m3, and the Xizhimen North traffic pollution monitoring point has reached a maximum of 993 μg / m3. Wang Yuesi, a researcher and doctoral supervisor at the Institute of Atmosp...
