Abstract

The invention discloses a hydrophobic sand preparation method adopting waste polystyrene foam, toluene and fine sand as raw materials. The main process includes adding the waste polystyrene foam to the toluene to form toluene solution of polystyrene, adding the fine sand to mix so as to enable the solution to distribute on the sand surfaces evenly, and obtaining the hydrophobic sand through recovering the toluene. The hydrophobic sand has good performance. The waste polystyrene foam and the fine sand are adopted as the raw materials, and a novel way of waste utilization comprehensively is expanded. The hydrophobic sand can be applied in water saving for city virescence, in moisture retention for drought area soil and in desert prevention, and can play an important role in the fields of waste utilization, water saving, desert prevention and the like.

Description

technical field [0001] The invention relates to a method for preparing hydrophobic sand used in urban gardens, sand control and other water-saving fields, in particular to a method for preparing hydrophobic sand by using waste polystyrene foam and fine sand as main raw materials. Background technique [0002] The invention mainly aims at the problems of current shortage of water resources, serious waste of irrigation water, increasingly serious desertification, serious public nuisance caused by discarded polystyrene foam and the like without rational utilization and the like. Use waste polystyrene foam and low-cost fine sand as raw materials to prepare a fine sand whose surface is covered with polystyrene. Since the surface of the sand is waste plastic, it will not retain water and is not hydrophilic, so it can be used Rainwater or irrigation water infiltrates into the ground smoothly; at the same time, because the surface of fine sand is not hydrophilic, it can effectively ...
