Problems solved by technology

[0004] The technical problem to be solved by the present invention is to add more additives such as ethylene glycol and propylene glycol to the traditional chemical inhibitors, and it is easy to freeze and freeze the sprinkler under low temperature conditions, resulting in the inability to spray, and the road surface after spraying. The shell of the shell also freezes, cracks or even fails due to low temperature, resulting in the defect that the dust suppression effect is not obvious. It provides a method of natural environmental protection dust suppression agent,

example 1

[0026] Weigh 3kg of fresh sugarcane, get bagasse and sugarcane juice respectively after squeezing the juice, and sugarcane juice for later use, dry the bagasse and put it into a pulverizer to pulverize it, pass through a 100-mesh sieve to get bagasse powder, and mix the sugarcane juice with a mass ratio of 1:5 Add bagasse powder to deionized water, add bagasse powder mass 3% sodium cetyl benzene sulfonate after mixing, mechanically stir and mix for 15 minutes to obtain a mixture, put the mixture in a microwave oven, and microwave at 500W for 4 minutes, microwave After the treatment, the bagasse mixed solution is obtained, and the pH value of the bagasse mixed solution is adjusted to 9 with a mass fraction of 10% sodium hydroxide solution. After the adjustment, 10% of the quality of the bagasse mixed solution is added in succession to carob gum and 6% of the quality of the bagasse mixed solution. Carboxymethyl starch sodium and bagasse mixed solution with 5% mass fraction of 2% ...

example 2

[0028]Weigh 5kg of fresh sugarcane, and obtain bagasse and sugarcane juice respectively after squeezing the juice, and the sugarcane juice is for subsequent use, put the bagasse into a pulverizer after drying, and pass through a 120-mesh sieve to obtain bagasse powder. Add bagasse powder to deionized water, add bagasse powder mass 5% sodium hexadecylbenzene sulfonate after mixing, mechanically stir and mix for 20 minutes to obtain a mixture, put the mixture in a microwave oven, and microwave it at 600W for 6 minutes, microwave After the treatment, the bagasse mixed solution is obtained, and the pH value of the bagasse mixed solution is adjusted to 10 with a mass fraction of 10% sodium hydroxide solution. After adjustment, carob gum with a quality of 12% of the bagasse mixed solution and 8% of the quality of the bagasse mixed solution are added successively. Carboxymethyl starch sodium and bagasse mixed solution with 10% mass fraction of 2% ammonium persulfate solution, heated t...

Abstract

The invention belongs to the technical field of flying dust management of roads and in particular relates to a preparation method of a natural and environment-friendly dust suppressant. The preparation method comprises the following steps: firstly, mixing bagasse powder with de-ionized water and sodium hexadecyl benzene sulfonate; carrying out microwave treatment to obtain a bagasse mixed solution; then regulating the pH (Potential of Hydrogen), adding carob gum and sodium carboxymethyl starch in sequence and reacting to obtain a reactant; mixing bagasse juice and sodium alginate and heating; adding N,N-dimethylacrylamide, hydroxyethyl methacrylate and a cross-linking agent; after cooling, adding the reactant; stirring and then regulating the pH; mixing with an ammonium persulfate solution and stirring and reacting to obtain the low-temperature-resisting natural and environment-friendly dust suppressant; the low-temperature-resisting natural and environment-friendly dust suppressant provided by the invention has a low-temperature-resisting property, can be freely sprayed under a low-temperature condition and is not frozen; after the low-temperature-resisting natural and environment-friendly dust suppressant is sprayed, a shell layer with certain thickness and strength is formed on the surface of a material; the shell layer is not broken by frosting and cracked under a low-temperature environment, does not cause ash, corrosion and secondary pollution and can be biologically degraded.

Description

technical field [0001] The invention belongs to the technical field of road dust control, and in particular relates to a preparation method of a natural environment-friendly dust suppressant. Background technique [0002] With the acceleration of urbanization, construction stockyards and road sand blowing are also increasing. Particulate matter pollution has a wide range of effects on urban air quality and is the primary cause of air pollution in most cities. Road dust in cities or open-pit mines is unorganized emission, and a large amount of dust will cause great pollution to the surrounding environment. The most important control method to suppress dust is sprinkling water. The main function of sprinkling dust suppression is to moisten fine dry dust particles to increase their relative density and bond them into larger particles so that they cannot fly under the action of external force. However, due to the weak binding force between dust and water, the water evaporates ...
