Dust suppressant for non-hardened pavement as well as preparation and application methods of dust suppressant

Abstract

The invention discloses a dust suppressant for a non-hardened pavement. The dust suppressant is prepared from the following raw materials in parts by weight: 160-165 parts of polypropylene glycol, 15-18 parts of hexadecane, 9-11 parts of octadecanol, 9-11 parts of an antifreezing solution and 1-2 parts of a preservative. Materials with water absorption capability are mostly used for preparing thedust suppressant in the current market or patents. As a result of hydrophilcity of soil, the pavement is muddy and is easily scoured by rainwater or evaporated by using the dust suppressant, so that the dust suppressant prepared with the method is not suitable for the non-hardened pavement. The dust suppressant in the patent is prepared from a hydrophobic material. After being constructed onto thesurface of soil, the dust suppressant achieves a purpose of inhibiting flying dust by increasing the proportion of fine soil particles. When vehicles pass, a dust cloud is avoided. As a result of excellent hydrophobicity and immiscibility to water, the dust suppressant is not scoured by rainwater easily. The material is relatively high in boiling point and is hard to evaporate to disappear, so that a dust suppression effect can be achieved effectively for a long time.

Description

technical field [0001] The invention relates to the technical field related to the prevention and control of dust diffusion, in particular to a dust suppressant for non-hardened road surfaces and its preparation and application methods. Background technique [0002] At present, dust suppressants can be divided into moisturizing and encrusting dust suppressants. Most of the moisture-retaining patents are for dust suppressants on hardened road surfaces, but there are very few dust suppressants for non-hardened roads (coal slime, dirt roads, etc.). When vehicles pass by on non-hardened roads, the driving of tires can easily raise fine particles on the road surface to form dust clouds, which seriously pollutes the surrounding environment and residents, and reduces visibility on the road surface, posing a great safety hazard. [0003] At present, most of the materials on the market or patents use water-absorbing materials to make dust suppressants. However, due to the hydrophili...

Problems solved by technology

When vehicles pass by on non-hardened roads, the driving of the tires can easily raise fine particles on the road surface, forming a dust cloud, which seriously pollutes the surrounding environment and residents, and reduces visibility on the road surface, posing a great safety hazard

[0003] At present, most of the materials on the market or patents use water-absorbing materials to make dust suppressants. However, due to the hydrophilic nature of the soil, the use of such dust suppressants will cause muddy road surfaces, and are easily washed away or evaporated by rainwater. The dust suppressant made by this method is not suitable for non-hardened pavement, so we propose a dust suppressant for non-hardened pavement and its preparation and application method to solve the above problems
