Sand fixing agent as well as preparation method, use method and application thereof

Abstract

The invention provides a sand fixing agent as well as a preparation method, a use method and application thereof, and relates to the technical field of environmental engineering. The sand fixing agentcomprises the following components: heteropolysaccharide and cellulose derivatives; and the mass ratio of the heteropolysaccharide to the cellulose derivatives is (5-15):(0.5-5). The sand fixing agent relieves the technical problem in the prior art of lack of a solid fixing agent which has good water-retaining effect, can maintain land fertility, guarantees that sandy soil in the land is not stuck into blocks after application, can be degreed in the natural world and avoids environmental pollution. The invention also provides a preparation method of the sand fixing agent. In addition, the invention also provides a use method of the sand fixing agent. According to the sand fixing agent, the sand fixing agent prepared by the preparation method of the sand fixing agent as well as the use method of the sand fixing agent, the sand fixing agent can be applied in the fields of sanded land agricultural planting, forestry wind prevention and sand fixation as well as sand desertification governance.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a sand-fixing agent and its preparation method, use method and application. Background technique [0002] Desertification is a major global ecological environmental problem facing mankind at present. Desertification areas are often accompanied by ecological problems such as surface drought and soil erosion, which in turn lead to agricultural and forestry problems, seriously hindering the growth and development of green plants and crops, resulting in seedling shortages, reduced production and Phenomena such as death have caused great harm to the national economy and social development. [0003] The sand-fixing materials used in the prior art include emulsified asphalt, phenolic resin, urea-formaldehyde resin, polyacrylamide, styrene-butadiene latex, etc. After application, although they can play the purpose of windproof and sand-fixing, because they are difficult...

AI Technical Summary

Problems solved by technology

However, the amount of application is relatively large, and the spraying thickness of the sand-fixing agent needs to reach 0.5-5cm, which is costly and requires watering for 20-30 days after spraying, which greatly wastes water resources, has poor water retention effect, and has no effect of increasing soil fertility; Therefore, it is of great practical value to develop a sand-fixing product and method that has a small application amount, good water retention effect, can maintain land fertility, and can be degraded in nature without causing environmental pollution.
