Frozen soil stabilizer
The invention relates to the field of frozen soil improvement, and discloses a frozen soil stabilizer which comprises an agent A and an agent B in any proportion, each agent A comprises the following components in parts by mass: strong acid cation exchange resin and water, and each agent B comprises the following components in parts by mass: composite organic glue, epoxy modified silicone oil, polyether modified silicone oil, a composite emulsifier and water. The invention has the following advantages and effects: in the application, the strong-acid cation exchange resin can exchange strong-hydrophilic metal ions on the surfaces of soil particles into weak-hydrophilic metal ions, so that the adsorption capacity of fine-grained soil particles on a water layer on the surface is reduced, and the discharge of water in frozen soil is promoted. On the other hand, the agent B is emulsion with a bonding effect. When the agent B enters capillary tubes among soil particles, the water-phase composite organic glue mainly adheres fine-grained soil to form coarse-grained soil, so that the surface area is reduced.
本发明涉及冻土改良领域，公开了一种冻土稳定剂，包括任意比例的A剂和B剂，其中：每份A剂包括以质量份数计的以下组分：强酸性阳离子交换树脂，水，每份B剂包括以质量份数计的以下组分：复合有机胶，环氧改性硅油，聚醚改性硅油，复合乳化剂，水。本发明具有以下优点和效果：本申请中，强酸性阳离子交换树脂可以将土壤颗粒表面的强亲水性金属离子交换成弱亲水性金属离子，使得细粒土颗粒对表面的水层吸附力下降，促进冻土水分的排出。另一方面，B剂是一种具有粘结效果的乳浊液。在B剂进入土壤颗粒之间的毛细管内时，水相的复合有机胶主要将细粒土之间互相粘附起来，形成粗粒土，以降低表面积。
