Bio-based high-water-resistance liquid soil stabilizer and preparation method thereof

Abstract

The invention relates to the technical field of soil stabilizers, in particular to a bio-based high-water-resistance liquid soil stabilizer and a preparation method thereof. The invention provides a bio-based high-water-resistance liquid soil stabilizer. The bio-based high-water-resistance liquid soil stabilizer comprises the following components in parts by mass: 8-15 parts of water-soluble cellulose; the organic matter comprises a bio-based and a bio-based derivative; the inorganic matter comprises a lithiate, a calcification and a phosphorus aluminide; and 40 parts of a solvent. The invention also provides a preparation method of the bio-based liquid soil stabilizer with high water resistance. The soil stabilizer has the characteristics of greenness and reproducibility, the process steps are simple, the raw material utilization rate is high, the production cost is low, the curing performance of the soil stabilizer is improved by adopting a method of compounding organic matters and inorganic matters, the water resistance of the cured soil is effectively improved, the service life is prolonged, and the soil stabilizer is suitable for curing soil with different acid-base properties.

Description

technical field [0001] The invention relates to the technical field of soil curing agents, in particular to a bio-based highly water-resistant liquid soil curing agent and a preparation method thereof. Background technique [0002] Soil stabilizer is a new type of environmental protection and energy-saving engineering material that can physically and chemically interact with soil components to change soil properties. It originated in the United States and other developed countries in the 1950s. It is mainly used to replace traditional solidified materials such as cement, lime and fly ash. It is characterized by less consumption, high efficiency and adjustable performance, and has been widely used. Used in roads, water conservancy, airport runways and slope soil conservation and other fields. Compared with traditional curing materials, in addition to its excellent engineering properties, it also has the advantage of being harmonious and unified with ecology through formula d...

[0005] The patent with the publication number CN109135761A discloses a novel environmentally friendly soil curing agent, the disclosed components of which are 10-25 parts of an alkyl metal compound, 5-10 parts of triisopropanolamine, 6-20 parts of polyacrylate, water soluble 12-25 parts of permanent cellulose, 5-10 parts of phosphate, 3-8 parts of ferrous sulfate, and the rest are solvents. This application uses divalent metal ions to solidify the soil, which is not friendly to the environment and is likely to cause environmental damage.

[0006] The patent with the publication number CN105038806B discloses a polymeric organic soil stabilizer and its synthesis method. The disclosed components are proportioned in parts by weight: 2-6 parts of magnesium chloride, 4-8 parts of calcium chloride, 0.3- 0.8 parts of calcium oxide, 0.3-0.8 parts of magnesium oxide, 3-8 parts of acrylamide, 0.1-0.4 parts of ammonium persulfate, 0.2-0.6 parts of potassium persulfate, 10-20 parts of soluble cellulose, 5-15 parts of carboxymethyl Sodium cellulose, 0.5-1 part of sodium hydroxide, 50-70 parts of water, acrylamide, ammonium persulfate and potassium persulfate are used in the raw materials of this application, the risk is high in the production process, and the produced soil stabilizer is easy to Destroy the soil environment

[0007] The patent with the publication number CN101525541B discloses a soil stabilizing agent, which consists of two compositions: a soil stabilizing agent and a soil curing agent, and discloses that the soil curing agent consists of 17-25 parts of polyvinyl alcohol, 4-8 parts of polyvinyl 3-6 parts, 3-6 parts of hydroxyethyl cellulose, 5-10 parts of polyethylene glycol, 2-4 parts of hydroxypropyl methylcellulose, 47-69 parts of water, the application utilizes soil stabilizer and soil curing agent to make The soil changes from hydrophilic to hydrophobic, which reduces the plastic limit and liquid limit of clay. The price of raw materials is high, the process steps are cumbersome, and the production cost is high.
