The invention discloses a method for preparing hydrophobic sand from paraffin, toluene and fine sand. The method mainly comprises the following processes of: dissolving paraffin in toluene to prepare a toluene solution of the paraffin, adding fine sand and stirring so as to enable the toluene solution of the paraffin to be uniformly distributed on the surface of the sand, and recovering toluene, cooling and packaging to obtain hydrophobic sand. The hydrophobic sand prepared by the method is quite excellent in performance. The hydrophobic sand prepared by the method is applicable to the aspects of water conservation of urban landscaping, water maintenance of soil in arid region, and desert prevention and control, and is excepted to develop more important function in the previous fields.
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 using paraffin, toluene and fine sand as main raw materials. Background technique [0002] The invention mainly aims at the current problems of shortage of water resources, serious waste of irrigation water, increasingly serious desertification and the like. Use paraffin wax and low-cost fine sand as raw materials to prepare a fine sand whose surface is covered with paraffin wax. Since the surface of the sand is paraffin wax, it will not retain water and is not hydrophilic, so that rainwater or irrigation water can smoothly infiltrate into the ground ; At the same time, because the surface of the fine sand is not hydrophilic, it can effectively reduce the water absorption through the soil through capillary phenomenon, and then evaporate to cause the soil to lose wate...
