Preparation method of high-molecular chemical sand stabilization material with continuous structure

Abstract

The invention relates to a preparation method of a high-molecular chemical sand stabilization material with a continuous structure. The preparation method comprises the following steps: 1, preparing a calcium phosphate oligomer; 2, preparing a free radical initiation system; and 3, preparing the high-molecular sand stabilization material with a continuous structure. The mechanical property of the high-molecular chemical sand-fixing material is improved by weakening the interface repulsion between organic and inorganic materials, and the high-molecular chemical sand-fixing material is characterized in that (1) the mutual fusion of the organic material and the inorganic material is ensured through the cross-linking polymerization of unsaturated monomers / inorganic oligomers at the molecular level and the acting force between multiple molecules; (2) the internal structure of the sand stabilization material is continuous and uniform, and the sand stabilization material has higher mechanical property and wind erosion resistance; and (3) the calcium phosphate oligomer can provide nutrition supply for plant growth.

Description

technical field [0001] The invention relates to a preparation method of a polymer chemical sand-fixing material with a continuous structure. Background technique [0002] China is one of the countries in the world that is seriously harmed by desertification. The total area of ​​desert and desert land is 1.28 million km 2 , accounting for 13% of the total land area of ​​the country. With the increase of desertified land, desert phenomena such as sandstorms, blowing sand, and floating dust are also increasing rapidly, which has a serious impact on my country's industrial and agricultural production, people's lives and health. Desertification has become China's Environmental issues that need to be addressed urgently. At present, the common sand fixation methods are divided into engineering sand fixation, plant sand fixation and chemical sand fixation. Compared with the other two sand fixation methods, chemical sand fixation has the advantages of lower cost and convenient operat...

Problems solved by technology

The study found that it is difficult to further improve the mechanical properties of the polymer sand-fixing agent through physical doping, which makes it difficult to resist the erosion of high wind speed

The present invention understands that due to the phase interface existing between the organic-inorganic materials, the self-structure is discontinuous, which makes it difficult to further improve the mechanical properties of the synthesized polymer sand-fixing materials
