Problems solved by technology

However, the cellulose raw material used in this process is cellulose cotton pulp, cellulose wood pulp or pulp factory, shipyard, which is taken out by the degreasing liquid during the pulping process and precipitates waste cellulose. For the supply of raw materials location is limited
In addition, the patented production process needs to be carried out under the protection of nitrogen, so it may cause complicated production equipment

Embodiment 1

[0026] The stalks of Solidago canadensis are pulverized with a micro-plant pulverizer to obtain plant powder. The plant powder was treated with 12% sodium hydroxide at 95°C for 30 minutes, washed until neutral, and dried in a vacuum oven at 60°C. Then add 95% ethanol solution to soak for 5 hours, dry and set aside.

[0027] The preparation of the solution is as follows: Dissolve 0.8g of dispersant gelatin in 70ml of distilled water, heat it at 80°C to dissolve it in water quickly; dissolve 0.15g of benzoyl peroxide in 5ml of toluene; dissolve 0.01g of hexadecane Trimethylammonium bromide was dissolved in 5ml of toluene.

[0028] Pour the prepared dispersant solution into a 500ml round bottom flask, add the pretreated cellulose, 15ml of methyl methacrylate and n-butyl methacrylate (MMA / BMA) mixed monomer, the prepared over Oxidize benzoyl and cetyltrimethylammonium bromide, use an ultrasonic cleaner to remove oxygen in the solution to mix evenly, and then under the action of ...

[0030] The stalks of Solidago canadensis are pulverized with a micro-plant pulverizer to obtain plant powder. The plant powder was treated with 12% sodium hydroxide at 95°C for 30 minutes, washed until neutral, and dried in a vacuum oven at 60°C. Then add 95% ethanol solution to soak for 5 hours, dry and set aside.

[0031] The preparation of the solution is as follows: Dissolve 1.5g dispersant gelatin in 70ml distilled water, heat it at 80°C to dissolve it in water quickly; dissolve 0.75g benzoyl peroxide in 5ml toluene; dissolve 0.065g hexadecane Trimethylammonium bromide was dissolved in 5ml of toluene.

[0032] Pour the configured dispersant solution into a 500ml round-bottomed flask, add the pretreated cellulose, 30ml methyl methacrylate and n-butyl methacrylate (MMA / BMA) mixed monomer, the configured over Oxidize benzoyl and cetyltrimethylammonium bromide, use an ultrasonic cleaner to remove oxygen in the solution to mix evenly, and then under the action of a magnetic ...

Embodiment 3

[0034] The stalks of Solidago canadensis are pulverized with a micro-plant pulverizer to obtain plant powder. The plant powder was treated with 12% sodium hydroxide at 95°C for 30 minutes, washed until neutral, and dried in a vacuum oven at 60°C. Then add 95% ethanol solution to soak for 5 hours, dry and set aside.

[0035] The preparation of the solution is as follows: Dissolve 1.2g of dispersant gelatin in 70ml of distilled water, heat it at 80°C to dissolve it in water quickly; dissolve 0.5g of benzoyl peroxide in 5ml of toluene; dissolve 0.01g of hexadecane Trimethylammonium bromide was dissolved in 5ml of toluene.

[0036]Pour the prepared dispersant solution into a 500ml round bottom flask, add the pretreated cellulose, 17.5ml of methyl methacrylate and n-butyl methacrylate (MMA / BMA) mixed monomers, and the prepared Benzoyl peroxide and cetyltrimethylammonium bromide, use an ultrasonic cleaner to remove oxygen in the solution to mix evenly, and then under the action of...

Abstract

The invention relates to a preparation method of a high oil-absorption material based on an invasive plant. The method comprises the following steps: crushing stalk of an invasive plant-solidago Canadensis, pre-treating by an aqueous alkali and ethanol solution, adding in gelatin solution, orderly adding a hybrid reaction monomer, an initiator and a crosslinking agent, mixing under an ultrasonic cleaner to eliminate the bubble, flowing through a condensing reflow device, warming and reacting under the magnetic force stirring effect, washing by hot water after the reaction, and drying to obtain the invasive plant based oil-absorption material. The method provided by the invention is simple to operate, the ultrasonic cleaner can be used for promoting the reaction, the raw material is wide in resource, the utilized invasive plant is distributed in more than ten provinces and cities in China at present, the production cost of the product is reduced, the reclamation and environmental protection are realized, the oil-absorption multiplying power of the obtained product to the long-chain oil reaches a maximum of 25g / g.

Description

technical field [0001] The invention belongs to the field of high oil-absorbing materials, in particular to a method for preparing high-oil-absorbing materials based on invasive plants. Background technique [0002] In the 1980s, research conducted by the Expert Group on Marine Pollution Science (GESAMP) showed that oil pollution is the most serious factor in marine pollution. Among them, 45% of oil pollution comes from marine transportation, including oil spill accidents; 36% comes from urban and industrial wastewater discharge, and a small part comes from natural sources and weather changes. It can be seen that a large amount of oil pollution mainly comes from man-made sources. The large amount of oil pollutants dumped into the sea every year is about 400,000 tons. In order to reduce the harm of oil to the environment, people are more and more urgent to develop oil recovery technology. At present, the fence method, dispersion method, adsorption method, coagulation method ...
