Embodiment 1～16

[0080] A preparation method of dust suppressant, comprising the steps of:

[0081] Mix the cellulose material and the dispersion liquid of the dust suppression auxiliary agent according to the formula amount in Table 1, and obtain 100 g of the dust suppression agent after ultrasonic dispersion.

[0082]

[0083]

[0084] A1, A2, A3, A4, A5 and A6 are all micronano lignocellulose, the lignin content in A1 and A2 is 25wt% respectively, the lignin content in A3 and A4 is 13wt%, and the lignin content in A5 and A6 The content is 37wt%. B1 and B2 are nanocellulose with a cellulose content of 99 wt%. C1 and C2 are micro-nano cellulose with a cellulose content of 99 wt%. D1 is micro-nano cellulose, the cellulose content is 99wt%, and the aspect ratio is 40. D2 is micro-nano cellulose with a cellulose content of 99 wt% and an aspect ratio of 70. D3 is micro-nano cellulose with a cellulose content of 99 wt% and an aspect ratio of 70.

Abstract

The invention relates to a dust suppressant. The dust suppressant comprises water and cellulose matters, wherein the cellulose matters are dispersed into the water; the content of cellulose matters is1 to 10wt%; more than 80wt% of components (except water) is the cellulose matters; the diameter of the cellulose matter is 50 to 1000nm, and the ratio of length to diameter is greater than or equal to 50. The dust suppressant has the advantages that the cellulose matter with special size is selected; the cellulose matters within the size are mutually bonded to form a network; the dust suppressantis accelerated to form a film, the fine dust is firmly caught, and is prevented from flying into the air to form secondary dust, and the dust suppressing cycle is long.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a dust suppressant, a preparation method and an application. Background technique [0002] Many human activities generate dust. With the continuous development of our country's economy, the output and usage of coal are also increasing, and the problem of dust in coal yards and ash yards has aroused people's attention. At the same time, with the high-intensity economic activities in the city and its surrounding areas, large-scale urban construction, and high-speed road traffic, there have been many soil stockpiles, which have caused serious pollution to the atmospheric environment and are harmful to human health and Environmental ecology has caused serious harm. [0003] At present, the main dust suppression methods are mainly dust removal by sprinkling water and dust suppression agent. Sprinkling and dust removal is mainly through wetting fine dry d...
