Abstract

The invention discloses a method for preparing hydrophobic sand by taking paraffin and waste polyethylene plastic as raw materials. The main craft process is that paraffin is melt to prepare paraffin meltwater, fine sand is added and stirred to enable the paraffin and the polyethylene plastic to be uniformly distributed on the surface of the sand, and then cooling and packing are conducted to obtain the hydrophobic sand. The hydrophobic sand prepared through the method has good properties, can be applied to water saving in urban landscaping, retention of water in soil in an arid area, desert prevention and the like, and is expected to play a great role in the above 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 with paraffin wax, waste polyethylene plastic 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 waste polyethylene plastic and fine sand as raw materials to prepare a fine sand whose surface is covered with paraffin wax and polyethylene plastic. Since the surface of the sand is paraffin wax and plastic, it will not retain water and is not hydrophilic. Water can make rainwater or irrigation water infiltrate into the ground smoothly; at the same time, because the surface of fine sand is not hydrophilic, it can effectively reduce water absorption through the ...
