Abstract

The invention aims to solve the problem of poor wettability of a bonding type dust suppressant, provides a bonding type dust suppressant for road dust and a preparation method of the bonding type dustsuppressant, and belongs to the technical field of dust suppressants. The bonding type dust suppressant is prepared from the following raw material components in percentage by mass: 0.1-1% of a humectant, 2-5% of polyvinyl alcohol, 0.5-9% of adhesive, 0.5-4.5% of a surfactant and the balance of water. The dust suppressant is environment-friendly in component, good in wettability and small in loss, and the dust suppression effect reaches 90% or above.

Description

technical field [0001] The invention belongs to the field of road dust control, and in particular relates to a bonded dust suppressant for open-pit mine roads and a preparation method thereof. Background technique [0002] According to the survey, in the automobile transportation operation of open pit mines in my country, the dust intensity of automobiles is the first among all open pit mining operations, and it is the largest source of dust pollution in open pit mines. Due to the rolling of heavy trucks during the transportation of mine ore, the road surface is more likely to generate dust. [0003] The traditional method of dust-proof pavement in open-pit mines is to sprinkle water with sprinklers, but production practice shows that the method of sprinkling water is more suitable for permanent concrete pavement under the condition of temperature above zero, but such pavements are rare in open-pit mine stopes. Most of the mines are crushed gravel roads, and some are tempor...
