example 1

[0017] Weigh 3kg of bagasse, dry it naturally, put it into a pulverizer and crush it, pass through a 100-mesh sieve, put the sieved bagasse powder into a steam explosion tank, and feed 20L of sulfur dioxide, then heat it to 190°C, and then pour it into the steam explosion tank Water steam was introduced into the tank until the pressure in the tank was 1.6 MPa. After maintaining the pressure for 5 minutes, the valve of the steam explosion tank was opened to release the pressure. After the pressure was released to normal pressure, it was filtered, and the filter residue was washed with 70°C deionized water for 3 times to obtain steam explosion treatment. Bagasse powder: Weigh 100g of the above-mentioned bagasse powder after steam explosion treatment, soak in 500mL hydrogen peroxide solution with a mass fraction of 10%, and react in a constant temperature water bath at 70°C for 1h to obtain a mixed solution, and then use a mass fraction of 5% hydrogen peroxide Sodium oxide solutio...

[0020]Weigh 4kg of bagasse, dry it naturally, add it to a pulverizer, and pass it through a 100-mesh sieve. Put the sieved bagasse powder into a steam explosion tank, and put 25L of sulfur dioxide into it, then heat it to 200°C, and then pour it into the steam explosion tank. Water steam was introduced into the tank until the pressure in the tank was 1.8 MPa. After maintaining the pressure for 7 minutes, the valve of the steam explosion tank was opened to release the pressure. After the pressure was released to normal pressure, it was filtered, and the filter residue was washed 4 times with 75°C deionized water to obtain steam explosion treatment. Bagasse powder: Weigh 160g of the above-mentioned bagasse powder after steam explosion treatment, soak in 560mL hydrogen peroxide solution with a mass fraction of 10%, and react in a constant temperature water bath at 75°C for 1.5h to obtain a mixed solution, and then use a mass fraction of 5% Sodium hydroxide solution adjusted the pH...

example 3

[0023] Weigh 5kg of bagasse, dry it naturally, add it to a pulverizer, and pass it through a 100-mesh sieve. Put the sieved bagasse powder into a steam explosion tank, and add 30L of sulfur dioxide, then heat it to 210°C, and then pour it into the steam explosion tank. Water steam was introduced into the tank until the pressure in the tank was 1.9 MPa. After maintaining the pressure for 8 minutes, the valve of the steam explosion tank was opened to release the pressure. After the pressure was released to normal pressure, it was filtered, and the filter residue was washed with 80°C deionized water for 5 times to obtain the steam explosion treatment. Bagasse powder: Weigh 200g of the above-mentioned bagasse powder after steam explosion treatment, soak it in 600mL hydrogen peroxide solution with a mass fraction of 10%, react in a constant temperature water bath at 80°C for 2h to obtain a mixed solution, and then use a mass fraction of 5% hydrogen peroxide Sodium oxide solution adj...

Abstract

The invention relates to a preparation method of an environment-friendly dust suppressant and belongs to the technical filed of dust suppressants. The dust suppressant comprises the following steps: taking bagasse as a raw material, adding sulfur dioxide as a catalyst and hydrolyzing hemicelluloses, lignin and the like through steam blasting treatment; then dissolving, removing impurities, preparing bagasse celluloses, grafting and modifying with acryl amide to improve the wettability and the film-forming property; finally mixing with soya bean meal, sodium dodecyl benzene sulfonate, polyvinyl alcohol and the like to prepare the environment-friendly dust suppressant. The environment-friendly dust suppressant prepared by the preparation method provided by the invention has the benefits that after the environment-friendly dust suppressant is sprayed, a layer of thin film is easy to form on the soil surface, so that the effect of protecting surface soil is realized; when in use at a normal temperature, the environment-friendly dust suppressant has better bonding property, good moisture preservation property and better water stability, and can effectively resist rainwater washing, the moisture preservation time can reach 80 hours or above, and the dust suppression efficiency is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly dust suppressant, belonging to the technical field of dust suppressants. Background technique [0002] Dust refers to solid particles suspended in the air. According to the International Organization for Standardization, suspended solids with a particle size of less than 75 μm are defined as dust. There are many sources of dust, such as urban expansion, mining and quarrying, coal transportation, metal smelting and a series of fields closely related to human activities and industrial development, all of which inevitably produce a large amount of dust to a certain extent; at the same time, artificial damage to vegetation causes Land desertification, and then the formation of wind and sand weather is also a very important reason. Soil and rocks are split into many fine particles after weathering, and pollen, spores and other organic particles float in the air to form dust; the exhau...
