Abstract

The invention discloses a hydrophobic sand preparation method adopting wax and fine sand as raw materials. The main process includes heating the wax to form wax liquid, adding the fine sand to mix so as to enable the wax to distribute on sand surfaces evenly, and obtaining the hydrophobic sand. The hydrophobic sand can be applied in water saving for city virescence, in moisture retention for drought area soil, in desert prevention and the like, and can play an important role.

Description

Technical field

[0001] The invention relates to a method for preparing hydrophobic sand that can be used in urban gardens, sand control and other water-saving fields, in particular to a method for preparing hydrophobic sand using paraffin wax and fine sand as raw materials. Background technique

[0002] The present invention is mainly aimed at the current shortage of water resources, serious waste of irrigation water, and increasingly serious problems of desertification. Use paraffin and low-cost fine sand as raw materials to prepare a fine sand covered with paraffin. Because the surface of the sand is paraffin, it does not retain water and is not hydrophilic, which can allow rainwater or irrigation water to penetrate the ground smoothly ; At the same time, because the surface of fine sand is not hydrophilic, it can effectively reduce water absorption through the soil through capillary phenomenon, and then evaporate to cause soil loss.

[0003] Since the present invention uses par...
