Embodiment 1

[0057] Embodiment 1: Non-polluting road surface dust suppressant of the present invention

[0058] First, 4.0 parts by weight of anhydrous magnesium chloride hygroscopic agent, 0.5 parts by weight of maltose humectant sold by Shandong Bailong Chuangyuan Biotechnology Co., Ltd. under the trade name of isomaltooligosaccharide and 0.5 parts by weight of The water-based polyurethane binder sold under the trade name Yoshida F0401 is put into a mixer, stirred and mixed evenly to obtain the described non-polluting road surface dust suppressant;

[0059] Then, according to the weight ratio of the non-polluting road surface dust suppressant to water of 9:91, the non-polluting road surface dust suppressant was added to the water, stirred evenly, completely dissolved, and then the obtained solution was sprayed on the road surface with a sprayer.

[0060] Carry out in the same way as above, just do not use anhydrous magnesium chloride hygroscopic agent, obtain a kind of road surface dust ...

Embodiment 2

[0065] Embodiment 2: Non-polluting road surface dust suppressant of the present invention

[0066] First, put 3.0 parts by weight of anhydrous calcium chloride hygroscopic agent, 1.0 parts by weight of triethanolamine humectant and 1.0 parts by weight of sodium lignosulfonate binder sold by Zibo Haobo Chemical Co., Ltd. under the trade name sodium lignosulfonate In the mixer, stir and mix evenly to obtain the non-polluting road surface dust suppressant;

[0067] Then, according to the weight ratio of the non-polluting road dust suppressant to water of 5:95, the non-polluting road dust suppressant is added to the water, stirred evenly, completely dissolved, and then the obtained solution is sprayed on the road surface with a sprayer.

[0068] Proceed in the same manner as above, except that the triethanolamine humectant is not used to obtain a road dust suppressant.

[0069] According to the standard method of GB / T15432-1995 "Gravimetric Method for Determination of Total Suspe...

Embodiment 3

[0073] Embodiment 3: the pollution-free road surface dust suppressant of the present invention

[0074] First, 2.0 parts by weight of calcium magnesium acetate hygroscopic agent, 2.2 parts by weight of xylitol humectant sold by Shandong Jurong Bioengineering Co., Ltd. The acrylate binder sold by the name of water-based acrylate is put into the mixer, stirred and mixed evenly, to obtain the described non-polluting road surface dust suppressant;

[0075] Then, according to the weight ratio of the non-polluting road dust suppressant to water of 5:95, the non-polluting road dust suppressant is added to the water, stirred evenly, completely dissolved, and then the obtained solution is sprayed on the road surface with a sprayer.

[0076] Proceed in the same manner as above, except that no acrylate binder is used to obtain a road dust suppressant.

[0077] According to the standard method of GB / T15432-1995 "Gravimetric Method for Determination of Total Suspended Particulate Matter i...

Abstract

The invention relates to a pollution-free road surface dust depressor and an application method thereof. The pollution-free road surface dust depressor is prepared from the following components in parts by weight: 2.0 to 4.0 parts of a moisture absorbent, 0.5 to 2.2 parts of a humectant and 0.3 to 1.0 part of a binding agent. After the road surface dust depressor provided by the invention is sprayed, the average reduction capability of PM10 (Particulate Matter 10) can reach 36.8mu g/m<3> and the average reduction capability of PM2.5 (Particulate Matter 2.5) can reach 20.1mu g/m<3>. When the road surface dust depressor provided by the invention is sprayed, the condition that the concentration of particulate matters is increased, caused by a vehicle, can be effectively inhibited, and the concentration of atmospheric particulate matters in a near road surface range can also be reduced. A sprayed road surface still has a good dust depression effect, and the effective time can last for 2 to3 weeks.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection. More specifically, the present invention relates to a non-polluting road surface dust suppressant, and also relates to a method for using the non-polluting road surface dust suppressant. 【Background technique】 [0002] As we all know, dust pollution is one of the world's public hazards, and road dust is an important part of dust pollution. As far as the current situation of road dust is concerned, open-pit mine roads are generally earth-rock or gravel roads with low grade and poor quality. The main problem of this kind of road is dust suppression on the road surface. When heavy-duty trucks are running, the dust content in the air is as high as 0.5-1g / m 3 Above, hundreds of times more than the national health standards, resulting in serious dust pollution. Urban hardened road dust is the main source of urban secondary dust. At present, people have carried out a lot of resear...
