Preparation method of multifunctional liquid membrane sand-fixing agent

Abstract

The invention discloses a preparation method of a multifunctional liquid membrane sand-fixing agent, which belongs to the field of chemical agriculture and forestry materials, is mainly applied to the treatment of land desertification, wind prevention and sand fixation, can prevent and control desertification and protect slopes on sand roads and sand railways, and can be applied to agricultural liquid mulching films. In the method, the multifunctional liquid membrane sand-fixing agent is prepared by taking asphalt or residual oil, bentonite, water glass and water soluble polymer as raw materials and by blending the raw materials with an emulsifier and a functional additive. The liquid membrane sand-fixing agent has obvious water collection and soil moisture preservation effects and therefore has the effect of promoting growth of plants and improving the stability of vegetation covers; and the organic combination of liquid membrane sand fixation with mechanical sand fixation and plant sand fixation greatly improves sand fixation effect and solves the problem of no irrigating sand fixation virescence in arid regions (the annual rainfall is 100 to 200mm).

Description

technical field [0001] The invention relates to a preparation method of a novel multifunctional liquid film sand-fixing agent, which belongs to the field of chemical agricultural and forestry materials, and is mainly used in land desertification control, windbreak and sand fixation, and can be used for sand control and slope protection on desert roads and desert railways; it can be applied Used in agricultural liquid mulch. The method uses asphalt or residual oil, bentonite, water glass, water-soluble polymer, etc. as raw materials, and is prepared by blending emulsifiers and functional additives. Background technique [0002] The current sand fixation technologies generally include biological sand fixation, mechanical sand fixation and chemical sand fixation. The technology of using natural or synthetic organic or inorganic cementitious materials to consolidate the sand surface to achieve the purpose of preventing sand movement, retaining moisture and collecting water, cha...

AI Technical Summary

Problems solved by technology

First, the cost is high and expensive, and it is difficult to reduce the cost per hectare to less than 1,000 yuan; second, the emulsification and atomization process is complicated, and the machinery and equipment are heavy and require strong power; third, it is difficult to degrade and eliminate residual poison

In the prior art, there are reports involving the use of residual oil or asphalt, but the materials used are single, the emulsion stability time is short, the emulsion is easily broken during use, and the construction operation is inconvenient, etc.
