Problems solved by technology

At present, the main method of pavement dust prevention is sprinkling method, which is simple to operate, but the disadvantage is that the dust suppression time is short, resulting in high sprinkling frequency and excessive water consumption; now there are chemical dust suppression agents for road dust prevention, mainly through Adding chemical substances with bonding and curing effects to the components will cause the dust particles to gather, become larger and settle, but this type of dust suppressant is not easy to degrade and will cause secondary pollution to the environment, so it is not suitable for road dust suppression

Embodiment 1

[0011] An environment-friendly road dust suppressant, comprising the following raw materials in parts by mass: 4 parts of sorbitan monolaurate, 5 parts of sorbitan monostearate, 2 parts of sodium lactate, and 3 parts of sodium pyrrolidone carboxylate , 3 parts of glycerin, 150 parts of water.

[0012] The preparation method of the present invention comprises the following steps: at 45°C, mix and stir sorbitan monolaurate, sorbitan monostearate and glycerol evenly, cool down to 35°C, add sodium lactate and pyrrolidone Sodium carboxylate, after stirring evenly, add water and stir evenly to obtain the finished product of the present invention.

Embodiment 2

[0014] An environment-friendly road dust suppressant, comprising the following raw materials in parts by mass: 18 parts of sorbitan monolaurate, 24 parts of sorbitan monostearate, 6 parts of sodium lactate, and 5 parts of sodium pyrrolidone carboxylate , 7 parts of glycerol, 160 parts of water.

[0015] The preparation method of the present invention comprises the following steps: at 50°C, mix and stir sorbitan monolaurate, sorbitan monostearate and glycerol evenly, cool down to 35°C, add sodium lactate and pyrrolidone Sodium carboxylate, after stirring evenly, add water and stir evenly to obtain the finished product of the present invention.

Embodiment 3

[0017] Environmentally friendly road dust suppressant, comprising the following raw materials in parts by mass: 10 parts of sorbitan monolaurate, 13 parts of sorbitan monostearate, 5 parts of sodium lactate, 4 parts of sodium pyrrolidone carboxylate , 6 parts of glycerol, 155 parts of water.

[0018] The preparation method of this embodiment is the same as that of Example 1.

[0019]

[0020] The finished product obtained in the present invention is diluted with clear water at a ratio of 1:500, and sprayed with a sprinkler. The finished product of the invention has been preliminarily applied on the pavement of a certain city and achieved good results. The main road surface of the city has a lot of dust, and the traffic flow is relatively large, resulting in substandard air quality. After the finished product of the invention is applied, the dust pollution is obviously alleviated. The effect is as follows: the effective dust suppression time is 6 days, the dust suppression r...

Abstract

The invention provides an environment-friendly pavement dust suppressant and a protection method thereof. The dust suppressant is prepared from the following raw materials in parts by mass: 4 to 18 parts of sorbitan monolaurate, 5 to 24 parts of sorbitan monostearate, 2 to 6 parts of sodium lactate, 3 to 5 parts of sodium pyrrolidone-carboxylate, 3 to 7 parts of glycerin, and 150 to 160 parts of water. By adopting the environment-friendly pavement dust suppressant, the dust particles which are easy to fly can be quickly conglomerated into large particles to sink, thus the flying of dust on a pavement can be effectively prevented, and the acting efficiency is high; the dust suppressing effect can last for more than 6 days; the dust suppressing rate is up to 95%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an environment-friendly road dust suppressant and a preparation method thereof. Background technique [0002] Dust pollution is an important factor affecting the environment, and the control of road dust is particularly important for the control of dust pollution. At present, the main method of pavement dust prevention is water sprinkling, which is simple to operate, but the disadvantage is that the dust suppression time is short, resulting in high water sprinkling frequency and excessive water consumption; now there are chemical dust suppressants to carry out road dust prevention, mainly through Adding chemical substances with bonding and curing effects to the components will cause the dust particles to aggregate and settle down. However, this type of dust suppressant is not easy to degrade and will cause secondary pollution to the environment, so it...
