Inventor: PARK GUI HEUM
IPC: C09K3/22
Filed: 2021-01-20
Abstract: The present invention relates to a scattering dust inhibitor composition comprising a sulfosuccinate-based surfactant as an active ingredient. The scattering dust inhibitor composition according to the present invention prepared by diluting a sulfonate-based surfactant with 1000 to 3000 times (volume ratio) of water not only can effectively suppress the scattering of fine dust by condensing soil or fine dust in various environments such as a coal yard, civil engineering cutting site, open field soil, unpaved road, construction site, bare land, factory, barn, etc., but also can effectively remove static electricity such as coal dust and ash. In addition, the scattering dust inhibitor composition according to the present invention does not freeze or evaporate in high humidity or summer or winter weather, so that the scattering suppression time of fine dust can be maintained for 10 months or more with one spraying. In addition, since the scattering dust inhibitor composition does not contain harmful heavy metal substances and environmental hormones, the scattering dust inhibitor composition does not affect the health of workers and does not cause secondary environmental pollution as a water-dispersible product.
