Description
Technical Field
The invention belongs to the technical field of chemical sand fixation, and particularly relates to a hyperbranched epoxy oligosiloxane sand fixation material and a preparation method and application thereof.
Background
Chemical sand fixation is one of desertification control technologies, generally, a chemical sand fixation material is sprayed on a sand layer, the material permeates into the sand to wet and coat the sand, and along with the progress of chemical reaction, the material is changed from a liquid state to a solid state, so that loose sand is coagulated into a solidification body with certain strength, and the original shape can be maintained under the action of certain external force. Chemical sand fixation can be divided into two broad categories: inorganic and organic. Common inorganic materials include cement and water glass, and organic sand-fixing materials include petroleum asphalt materials, high-molecular polymer materials and the like. In the aspect of inorganic sand-fixing materials, cement sand-fixing materials are not easy to construct, and can obtain certain strength only by high-quality aggregates, and are generally rarely used as sand-fixing materials independently. The water glass has low mechanical strength after being solidified and is easy to be corroded by wind and rain. In the aspect of organic sand-fixing materials, the petroleum asphalt material is simple in construction process and low in raw material cost, but a formed solidification body is easy to disintegrate after being irradiated by sunlight and poor in weather resistance. The high molecular polymer material has high mechanical strength and convenient construction, but the viscosity of the system is high, in order to reduce the viscosity of the material system and improve the infiltration performance of the material, a large amount of small molecular substance diluents are usually added into the conventional high molecular base chemical sand fixing material system to have certain infiltration capacity, and the small molecular substances are volatile during solidification and damage constructors and the environment. Therefore, the existing sand fixing material is difficult to realize quick, convenient, high-performance, high-weather-resistant and environment-friendly sand fixing.
