Description

Surface sand-prevention, sand-fixation and dust-repellent agent, preparation method and application method thereof

Technical field

The invention relates to a sand-fixing and dust-proofing composition for soil surface in arid regions, a production method and a use method thereof, and is a surface sand-fixing and dust-proofing agent and a preparation method and a use method thereof.

Background technique

In arid areas, due to severe water shortage, not only plants cannot grow, but also the soil is prone to sandification and blows with the wind. In severe drought areas-desert areas, sand advances and people retreat, and wind and sand destroy farmland, houses, roads, etc., which damages the local ecological environment. Further deterioration, it is easy to cause sandstorms in the wind season.

The preparation method of the above-mentioned surface sand-preventing, sand-fixing and dust-proofing agent is carried out according to the following steps: put the required amount of water into the reactor, and slowly add the required amount of polyvinyl alcohol under stirring at 90 to 100°C And after the polyvinyl alcohol is completely dissolved, lower the temperature to 50°C to normal temperature, add the required amount of boric acid under stirring, and after stirring for 10 to 60 minutes, add the required amount of dodecyl chloride at 35°C to normal temperature ammonium chloride, and stirred for 10 to 30 minutes to obtain the surface sand-preventing and sand-fixing and dust-proofing agent.

The use method of above-mentioned surface sand-proof sand-fixing and dust-proofing agent is: on the ground that needs to carry out sand-proofing or/and sand-fixing or/and dust-proofing, spray 1500 to 1800 milliliters of surface sand-proofing sand-fixing and dustproofing agents per square meter to form a surface film.

The second technical solution of the present invention is achieved in that a surface sand-preventing, sand-fixing and dust-proofing agent contains 4 to 6% polyvinyl alcohol, 0.001 to 0.005% lauryl ammonium chloride and the remainder by weight. water.

The preparation method of the above-mentioned surface sand-preventing, sand-fixing and dust-proofing agent is carried out according to the following steps: put the required amount of water into the reaction kettle, slowly add the required amount of polyvinyl alcohol under stirring at 90 to 100° C. After the polyvinyl alcohol is completely dissolved, a required amount of dodecyl ammonium chloride is added at 50° C. to normal temperature, and stirred for 10 to 60 minutes to obtain a surface sand-preventing, sand-fixing and dust-proofing agent.

The use method of the above-mentioned surface sand-proofing sand-fixing and dustproofing agent is carried out according to the following steps: the first step, put the required amount of water into the reaction kettle, add 0.05 to 0.8% boric acid under stirring until all dissolve to obtain the first step Liquid; in the second step, the surface sand-prevention and sand-fixing and dust-proof agent is fully mixed with the first step liquid in a weight portion of 1:3 to 1:6 to obtain the second step liquid; the third step is to carry out sand control or/and For sand-fixing or/and dust-proof ground, spray 1500 to 1800 milliliters of the third-step liquid per square meter to form a surface film.

The surface sand-preventing, sand-fixing and dust-proofing agent of the present invention is easy to prepare and use. On the ground where sand-preventing or/and sand-fixing or/and dust-proofing is required, the present invention is used to form a surface film, and the surface film is not afraid of exposure in summer and freezing in winter , so that the soil on the surface is not moved by the wind, so that it has the effect of preventing sand, fixing sand and dust, and can reduce the evaporation of soil water, which is beneficial to plant growth, so it has a good effect on the ecological environment, and is beneficial to the development of resources and agricultural development in desert areas. play a positive role.
