example 1

[0025] In parts by weight, 100 parts of wood pulp with a solid content of 2%, 10 parts of sodium bromide, and 20 parts of oxidizing agent are successively poured into the reactor, and the pH is adjusted to 10.5 with a mass fraction of 8% sodium hydroxide solution. Then, at a temperature of 55°C and a rotation speed of 400r / min, the reaction was stirred at a constant temperature for 2 hours. After the reaction was completed, the materials in the reactor were transferred to a nano homogenizer, and homogenized three times at a pressure of 1800 bar to obtain nano fiber slurry, and the gained nanofiber slurry is filtered, washed and dried to obtain nanofibers; in parts by weight, 10 parts of nanofibers are successively taken, and 100 parts by mass fraction is 60% ethanol solution, and after mixing, the frequency is 40kHz Ultrasonic disperse for 20 minutes under the condition, and then add tetraethyl orthosilicate 1.2 times the mass of nanofibers to the ethanol solution under stirrin...

Abstract

The invention discloses an ecological environment sand fixing material and a preparation method thereof, which belongs to the technical field of sand environmental governance. The preparation method comprises the following steps: oxidizing and homogenizing wood pulp used as a raw material to obtain nano fibers, adsorbing silicon dioxide on the surface of the nano fibers, by adopting the silicon dioxide as a supporting material, slowing heating, carbonizing the nano fibers to obtain nano fibers of a hollow structure, taking the hollow nano fibers as carriers, respectively wrapping polyaspartic acid emulsion and a hexanediamine solution inside the hollow fibers, performing end-sealing treatment by virtue of urea resin, respectively preparing a fiber component A and a fiber component B, and then compounding with chitosan, glutaraldehyde, casein, borax, polyethylene glycol and the like, thus obtaining the ecological environment sand fixing material. The sand fixing material is short in setting time, has a good sand fixing effect, and is capable of creating a good water-soil environment to the growth of plants, capable of effectively improving the ecological environment, and capable of facilitating the growth of desert plants.

Description

technical field [0001] The invention discloses an ecological environment sand-fixing material and a preparation method thereof, belonging to the technical field of desertification environment control. Background technique [0002] The desertification of land has caused a series of serious ecological environment and social problems, posing a huge threat to human existence. The key to desertification control is sand prevention and sand fixation. Among the many desertification control technologies and prevention models, the more mature sand fixation methods are engineering sand fixation and biological sand fixation. However, due to the problems of high cost, low efficiency, high labor intensity, and slow construction progress, these prevention and control technologies have not been widely promoted and effectively implemented. In recent years, chemical sand-fixation technology and chemical sand-fixation materials have attracted increasing attention because of their high efficie...
