Problems solved by technology

However, some raw materials have high cost, some cannot create a good water and soil environment for plant growth, and some even pollute the environment.
For example, petroleum product dust suppressants are difficult to degrade after application, and stay in the surface sand for a long time, causing secondary pollution to the environment

Embodiment 1

[0023] A preparation method of the eco-friendly sand-fixing and dust-suppressing agent, the steps are as follows:

[0024] 1) Crushing and grinding the Suaeda salsa seed cake, passing through a 120-mesh sieve to obtain biomass powder;

[0025] 2) Cook 8.0g of the above biomass powder in 500mL of boiling water for 30 minutes to make it puff, then stop the heat supply, cool down to 65-75°C to obtain a biomass puff solution;

[0026] 3) At a stirring speed of 150r / min, sprinkle 4.0g of sodium dodecylbenzenesulfonate evenly into the above-mentioned biomass puffing solution to reduce the surface tension of the solution. After 10 minutes, adjust the stirring speed to 2000r / min min, quickly sprinkle 6.0g sodium carboxymethylcellulose into the above solution evenly to prevent agglomeration, stir for 40min, then slowly add the pre-prepared 4.0g / 100mL polyvinyl alcohol aqueous solution into the above solution , stop after stirring for 10 minutes to obtain a reaction solution, the tempe...

Abstract

An eco-friendly sand stabilization dust depressor is dark-brown milky liquid prepared by biomass materials, surfactants, water-soluble polymers, moisturizers, preservatives and water through mixing. The viscosity of the dust depressor is 50-80 centipoise at the normal temperature. The biomass materials are solid cake-like residues of plant seeds after a squeezing and oil pressing process or solvent digestion; the water-soluble polymers are carboxymethylcellulose and polyvinyl alcohol; and the moisturizers are magnesium chloride, calcium chloride, sodium sulfate, sodium silicate and the like. The obtained sand stabilization dust depressor is eco-friendly; and the preparation process is simple, short in process and easy to operate. The eco-friendly sand stabilization dust depressor has the advantages of being environment-friendly, non-toxic and free of pollution; and capable of effectively controlling soil wind erosion and land desertification, reducing dust weather, playing roles in sand stabilization, dust proofing and depression, and being widely used in severe wind erosive areas such as suburban farmlands, wastelands, degraded grasslands and deserts.

Description

technical field [0001] The invention relates to the preparation of a sand-fixing and dust-suppressing agent, in particular to an eco-friendly sand-fixing and dust-suppressing agent and a preparation method thereof. [0002] Made of biomass materials, it is highly efficient, energy-saving, and environmentally friendly. It is mainly used to prevent and control wind erosion of soil, control land desertification, and suppress dust. It belongs to the technical field of environmental pollution control. Background technique [0003] my country is the country with the largest area of ​​desertification and sandification in the world. Although land desertification has been curbed to a certain extent in recent years, it is still the most serious ecological problem at present. Land desertification can directly lead to wind erosion of loose grassland soil and urban suburban soil, which will cause sand and dust weather under the action of wind and cause wind and sand pollution in urban ar...
