Dust falling agent and preparing method thereof

Abstract

The invention relates to the technical field of raising dust controlling, and discloses a dust falling agent. The dust falling agent is prepared from, by mass, 0.1%-0.6% of carboxymethylcellulose, 0.3%-0.7% of polyacrylamide, 0.1%-0.6% of hydroxypropyl methyl cellulose, 0.1%-0.6% of lithium base bentonite, 0.8%-1.5% of glycerol and the balance water. The dust falling agent is good in dust fallingeffect, the raising dust index can be decreased to 0.2 g / m<2> to 10 g / m<2> from 60 g / m<2> to 80 g / m<2>, the obvious sticky feeling does not exist in the human body, and the effect can be kept for 8 hours; the invention also provides a preparing method for the dust falling agent.

Description

technical field [0001] The invention relates to the technical field of dust control, in particular to a dust reducing agent and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, people are paying more and more attention to air pollution, among which the dust on urban roads is a kind of air pollution that most directly affects people's lives. Flying dust is an open pollution source that enters the atmosphere due to the dust on the ground being driven by wind, man-made or other drives, and is an important part of the total suspended particulate matter in the ambient air. Flying dust is extremely harmful to human health. In mild cases, it can cause respiratory diseases and asthma; [0003] For dust reduction on urban roads, the currently adopted methods are: (1) Sprinkling water: This method is simple, does not pollute the environment, and is relatively low in cost. Equipped with a large wa...

Problems solved by technology

[0003] For dust reduction on urban roads, the currently adopted methods are: (1) Sprinkling water: This method is simple, does not pollute the environment, and is relatively low in cost. Equipped with a large water storage device, so the sprinkler equipment is bulky, takes up a lot of space, and has high manufacturing costs; (2) Dust suppressant: the main principle of existing dust suppressant is to use dust suppressant to wet and adhere to the dust, so that the dust absorbs moisture After gaining weight, thus settling

According to the standard test of the environmental sanitation department, the dust reduction effect of the existing dust suppressant can only be reduced from 60-80g per square meter to 20-40g per square meter. The mixture of dust and dust suppressant is relatively sticky, which is harmful to people. The sensory sense is obviously sticky, which will still affect people's driving and walking on urban roads
