Liquid soil stabilizer for improving water resistance and preparation method

Abstract

The invention relates to the technical field of soil stabilizers, in particular to a liquid soil stabilizer capable of improving water resistance and a preparation method, and the liquid soil stabilizer comprises the following components in percentage by mass: 6-16 parts of water-soluble biomass cellulose and organic biomass, the organic biomasses comprise glycerol and fatty acid derivatives; the invention relates to a water-soluble organic fertilizer, which is characterized by further comprising a bio-based and derivatives thereof, specifically comprising sodium dodecyl sulfate and sodium polycarboxylate, and further comprising inorganic matters, specifically comprising lithiates, calcified compounds and phosphorus aluminide; pure water is taken as a solvent, and the double-electrode-layer thickness of soil particles is changed by controlling the temperature as a main parameter, so that the soil particles are convenient to bond, and precipitates are generated to improve the water resistance. The water-soluble cellulose, the sodium dodecyl sulfate and the sodium polycarboxylate are adopted, so that the surfaces of soil particles are covered with oleophylic parts in organic matter macromolecules, overall stability of the particles and release of free water are facilitated, the hydrophobicity of the soil can be improved, and the problems in the background technology are solved.

Description

technical field [0001] The invention relates to the technical field of soil curing agents, in particular to a liquid soil curing agent for improving water resistance and a preparation method. Background technique [0002] Sustainable development is the theme of today's development. As the country pays more and more attention to ecological and environmental construction, resources such as sand and stone in construction industries such as buildings and roads have begun to be controlled, which has caused the cost of materials used in related industries to increase continuously. Therefore, biomass And soils such as natural silt are favored as sustainable alternatives. [0003] 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 tradition...
