Problems solved by technology

[0003] Soil stabilizer is a new type of energy-saving and environmentally friendly engineering material synthesized from various inorganic and organic materials to stabilize various soils. For the soil that needs to be reinforced, according to the physical and chemical properties of the soil, only a certain amount of curing agent is required. After mixing and compacting, the required performance index can be achieved. Compared with the use of traditional pavement base material road construction, it can save road construction costs and shorten the construction period. Without changing the construction conditions, no side effects The limiting compressive strength can be improved, the soil curing agent composite consolidated soil specimens will not dissolve when soaked in water at room temperature, good water stability, good durability, etc., the polymer soil curing agent is used in practical applications because of its high concentration and dosage It is less, easy to transport, and convenient to construct. It has been applied in many fields, but its impermeability, freeze-thaw resistance, and compression resistance need to be further improved to meet the requirements of more fields.

Description

technical field [0001] The invention relates to the field of curing agent preparation. More specifically, the present invention relates to a polymer soil stabilizer and a preparation method thereof. Background technique [0002] The essence of the soil is a kind of sol. Such a colloid has certain stability, and there is a certain distance between the colloidal particles, so the strength of the soil is relatively poor. For leakage prevention and other projects, soil with high density and high strength is required, and chemical substances need to be added to the soil to change the properties of the soil and facilitate the construction of the project; [0003] Soil stabilizer is a new type of energy-saving and environmentally friendly engineering material synthesized from various inorganic and organic materials to stabilize various soils. For the soil that needs to be reinforced, according to the physical and chemical properties of the soil, only a certain amount of curing age...
