Abstract
The invention discloses a method for preparing hydrophobic sand from waste grease and waste polystyrene foam by a melting process. The main technical process comprises the following steps: heating waste grease, and adding waste polystyrene foam to form a viscous liquid; and adding preheated fine sand, uniformly stirring, discharging, and naturally cooling to obtain the hydrophobic sand. The hydrophobic sand prepared by the method has favorable properties. By using the waste grease, waste polystyrene foam and fine sand as raw materials, the method develops a new road for comprehensive utilization of waste. The hydrophobic sand prepared by the method can be used in the aspects of water saving in urban landscaping as well as soil water retention and desert control in arid areas, and is hopeful to have great actions in the fields of waste utilization, water saving, desert control and the like.
Description
Technical field
The present invention relates to the preparation method for a kind of hydrophobic sand of other water saving fields application of city trees and shrubs, sand control and confession, refer in particular to the method for preparing hydrophobic sand with waste grease and waste polystyrene foam.
Background technology
The present invention is mainly for current shortage of water resources, irrigation water serious waste; Desertification is day by day serious, waste causes serious public hazards and there is no the problem of the aspects such as reasonable utilization.Utilize the fine sand fine sand that a kind of surface is covered by polystyrene for prepared by raw material that waste grease, waste polystyrene foam and cost are very low, because the surface of this sand is polystyrene, therefore can not retain moisture, and not hydrophilic, can make rainwater or irrigation water permeate the ground smoothly; Because the fine sand surface is not hydrophilic, can effectively reduce moisture and absorb water with capillarity by soil simultaneously, and then evaporation causes the soil dehydration.
Because the present invention is that to utilize waste grease, waste polystyrene foam and sand be main raw material, the hydrophobic sand of preparation is with low cost, yet there are no the relevant report of this aspect, and its unique performance will have broad application prospects it aspect desertification control and urban afforestation and beautification of landscape when preparation (if at husky surface attachment different colours).
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of hydrophobic sand, and it is raw material that this preparation method be take waste grease, waste polystyrene foam and fine sand, through reasonable proportioning, by certain technological process, makes hydrophobic sand.
The technical problem to be solved in the present invention is solved by following scheme: a kind of scorification prepares the method for hydrophobic sand with waste grease and waste polystyrene foam, it is characterized in that: waste grease is heated to 250
0c, add waste polystyrene formation of foam mucus; Add preheated fine sand, preheating temperature is 250
0c, stir, and obtains hydrophobic sand after discharging, naturally cooling, and wherein the mass ratio of waste grease, waste polystyrene foam and fine sand is 1:0.58: 18-28.
Waste polystyrene foam prepared with waste grease and waste polystyrene foam in the method for hydrophobic sand by above-mentioned a kind of scorification refers to: the discarded polystyrene foams such as packing and disposable lunch-box.
Advantage of the present invention is: the husky cost of the hydrophobic 1, prepared by present method is very low.2, the sand surface is covered by polystyrene and waste grease, thereby not hydrophilic.3, be applied to urban afforestation or desertification control and can save irrigation water, reduce evaporation to suppress the process of desertification, to reach the purpose of water saving and improvement desertification.4. can effectively utilize a large amount of waste polystyrene foams and waste grease, make rational use of resources and alleviate the pollution that waste causes.
The accompanying drawing explanation
Fig. 1 is that a kind of scorification prepares the process flow sheet of hydrophobic sand with waste grease and waste polystyrene foam.
