Problems solved by technology

[0003] In terms of road dust suppression, the main measure to reduce road dust and inhalable particulate matter is water sprinkling. The advantage of this method is that it is simple and easy to implement. The disadvantage is that the maintenance time of dust suppression is short and the water consumption is large. Therefore, it is necessary to invent an efficient dust suppression method. dust suppressant

Abstract

The invention discloses a moisturizing dust suppressant which comprises the following components: paraffin oil, castor oil, tricosanol, pentacosanol, octadecyl trichlorosilane, lauryl alcohol, polyvinyl alcohol, an inorganic salt additive, a filler and water. The invention also discloses a preparation method of the moisturizing dust suppressant. According to the preparation method, mullite and volcanic rock as raw materials are subjected to acid and alkali treatment, corn straw and sugarcane straw are subjected to high-pressure water steam closed blasting treatment, and then are mixed with themullite and the volcanic rock for calcining to form a porous structure, and substances such as the paraffin oil, the castor oil, the tricosanol, the pentacosanol and the octadecyl trichlorosilane canbe adsorbed; and during use, the adsorbed substances such as the paraffin oil, the castor oil and the tricosanol are gradually released, so that dust is wetted, and dust suppression period can be increased and dust suppression time can be prolonged by adding the filler.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, more specifically, the invention relates to a moisturizing dust suppressant and a preparation method thereof. Background technique [0002] At present, inhalable particulate matter is also a serious pollutant that endangers people's health. The largest sources of inhalable particulate matter are coal combustion and automobile exhaust emissions. Among them, automobiles, as a common means of transportation, produce pollutants not only from exhaust emissions, but also from dust brought in during driving and friction between tires and road surfaces. of carbon dust. [0003] In terms of road dust suppression, the main measure to reduce road dust and inhalable particulate matter is water sprinkling. The advantage of this method is that it is simple and easy to implement. The disadvantage is that the dust retention time is short and the water consumption is large. Therefore, it is necessary t...
