Abstract

The invention discloses a polymer sand-fixation agent, and belongs to the technical field of sand fixation. 2-amino-4-hydroxy-6-methylpyrimidine, hexamethylene diisocyanate and other matter are adopted as raw materials, functional multiple-hydrogen bond structural functional monomers are prepared, and acrylate monomers are introduced so as to form a polymer emulsion system containing multiple-hydrogen bond-constructed groups; azobenzene, cyclodextrin and disulfide bonds are introduced into the molecular chain of polyurethane, and 4,4'-dinitrodiphenyldiaminourea is adopted as a modifier for modification of graphene oxide so as to prepare a film-forming agent. The sand-fixation effect is improved through combination of the composite polymer emulsion, the composite modified polyurethane and the film-forming agent, and the problems of the poor film-forming property, no easy agglomeration of loose sand during application and a poor water retention effect of commonly used sand-fixation agents are solved, and the improvement effect is remarkable.

Description

technical field [0001] The invention discloses a polymer sand-fixing agent, which belongs to the technical field of sand-fixing. Background technique [0002] Desertification is a major global ecological environmental problem facing human beings. Desertified areas are often accompanied by ecological problems such as surface drought and soil erosion. . A series of agricultural and forestry problems caused by this have seriously hindered the growth and development of green plants and crops, resulting in shortage of seedlings, reduced production and death, wasting a lot of land resources and precious water resources. There are three main ways to control desertification: biological control technology, physical or mechanical control technology and chemical control technology. Chemical control technology refers to the application of organic or inorganic sand stabilization materials on the surface of desertified land to improve the stability and water retention of sandy soil, or ...
