Embodiment approach

[0040] As an embodiment of the present invention, the component A is a cationic surfactant.

[0041] As an embodiment of the present invention, the cationic surfactant is a cationic surfactant containing imidazole.

[0042] As an embodiment of the present invention, the hydrophobic chain of the imidazole-containing cationic surfactant is a long chain hydrocarbon chain.

[0043] As an embodiment of the present invention, the preparation method of the cationic surfactant is as follows:

[0044] (1) After adding 24mL toluene and 24mL dimethyl sulfoxide in the reactor, add 15g of imidazole, stir evenly and add 16g of 50wt% sodium hydroxide solution, and reflux until anhydrous is generated;

[0045] (2) Add 21.5g of 1,4-dibromobutane under stirring, heat up to 110°C and stir for 4 hours, then filter while hot to get the filtrate, distill off the solvent under a rotary evaporator, put the filtrate in a beaker, Add 60 mL of distilled water and place at room temperature for 12 hours...

Embodiment 1

[0084] Embodiment 1: This embodiment provides a kind of soil curing agent, and described soil curing agent is divided into A component and B component,

[0085] The A component includes water, ethanol, tourmaline, component A cationic surfactant and small molecule polyhydric alcohol;

[0086] The B component includes polysaccharide, component B surfactant, biological enzyme, calcium carbonate, complex compound, inorganic-organic compound, water and ethanol.

[0087] Tourmaline: The tourmaline is purchased from Lingshou County Zhenying Mineral Products Processing Factory, the type is fiber tourmaline, and the specification is 200 mesh.

[0088] Component A cationic surfactant: the component A cationic surfactant is a cationic surfactant containing imidazole, and its preparation method is as follows:

[0089] (1) After adding 24mL toluene and 24mL dimethyl sulfoxide in the reactor, add 15g of imidazole, stir evenly and add 16g of 50wt% sodium hydroxide solution, and reflux unti...

Embodiment 2

[0104] Example 2: The difference between this implementation and Example 1 is that the weight ratio of the A component and the B component is 1:2.

The soil curing agent is prepared from a component A and a component B; the component A is prepared from water, ethanol, tourmaline, a component A cationicsurfactant and low molecular polyol; the component B is prepared from polysaccharide, a component B surfactant, a biological enzyme, calcium carbonate, a complex compound, an inorganic-organic compound, water and ethanol.

Description

technical field [0001] The invention relates to the technical field of curing agents, in particular to a bio-enzyme composite soil curing agent and its application process. Background technique [0002] The traditional process used for road foundations is the use of cement to stabilize sand and gravel. To get rich, build roads first. With the development of economy, the road construction of countries all over the world has entered a stage of rapid development. The road construction materials that meet the needs of road engineering have not increased accordingly, and the total amount of sand and gravel materials traditionally used in roads or buildings has also decreased year by year due to continuous mining, and some areas have even been exhausted, while the mining conditions for sand and gravel resources in some areas are demanding. In contrast to this, a large number of building materials in demolition projects have been discarded. [0003] In the past 20 years, soil st...
