Method for manufacturing multifunctional sand fixing agent

Abstract

The invention relates to a method for manufacturing a multifunctional sand fixing agent, belongs to the field of chemical agricultural-forestry materials, is mainly applied to control of land desertification as well as wind breaking and sand fixation, can perform sand prevention and control as well as slope protection on desert highways and desert railways, and can be applied to agricultural liquid mulching film. The method comprises the following steps: using asphalt or residual oil, bentonite, water glass, water-soluble polymer and the like as raw materials; and blending an emulsifier and functional additives to prepare the sand fixing agent. The liquid film sand fixing agent has obvious effects of water collection and soil moisture conservation, thereby having effects of promoting plant growth and improving vegetation stability; organic combination of chemical sand fixation of the liquid film with mechanical sand fixation and mechanical sand fixation not only greatly improves the sand fixing effect, but also solves a problem of irrigation-free sand fixation and greening of dunes in arid areas (having an annual precipitation of 100 mm-200 mm).

Description

technical field [0001] The invention relates to a method for preparing a multifunctional sand-fixing agent, which belongs to the field of chemical agricultural and forestry materials. 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, changing soil structure, and changing surface temperature is called chemical sand fixation technology. Compared with biological sand fixation and mechanical sand fixation, chemical sand fixation not only has the advantages of fast construction speed, non-perishability and durability, but also has the effect of moisture conservation and water conservation, and is more suitable for use in arid and water-scarce areas.

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.
