Abstract
The invention discloses a kind of with waste polystyrene foam, toluene and fine sand for the method for hydrophobic sand prepared by raw material.Main processes joins in toluene by waste polystyrene foam, forms the toluene solution of polystyrene, adds fine sand and stir the surface making dissolution homogeneity be distributed in sand, namely obtains hydrophobic sand through reclaiming toluene.Hydrophobic sand performance prepared by this method is fine.This method is with waste polystyrene foam and fine sand for raw material, and this expands out a new road to waste ' s reclamation.Hydrophobic sand prepared by this method can be used for the water saving of urban afforestation, and water tariff collection and the desert of arid area soil prevent and treat aspect, are expected to play very large effect in fields such as waste utilization, water saving and desertification controls.
Description
Technical field
The present invention relates to for city trees and shrubs, sand control and a kind of preparation method of hydrophobic sand for the application of other water saving fields, refer in particular to waste polystyrene foam and fine sand as primary raw material is to prepare the method for hydrophobic sand.
Background technology
The present invention is mainly for current shortage of water resources, irrigation water serious waste; Desertification is day by day serious, waste polystyrene foam etc. is caused serious public hazards and is not had the problem of the aspects such as Appropriate application.The very low fine sand of waste polystyrene foam and cost is utilized to prepare the fine sand that a kind of surface covers by polystyrene for raw material, surface due to this sand is waste plastics, therefore moisture can not be retained, and not hydrophilic, rainwater or irrigation water can be made to permeate the ground smoothly; Simultaneously because fine sand surface is not hydrophilic, can effectively reduce moisture and be absorbed water with capillarity by soil, and then evaporation causes soil dehydration.
Because the present invention utilizes polystyrene and sand to be primary raw material, the hydrophobic sand of preparation is with low cost, yet there are no the relevant report of this aspect, and the performance of its uniqueness makes it will have broad application prospects in desertification control and urban afforestation and beautification of landscape (if at the surface attachment different colours of sand during preparation).
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 this preparation method for primary raw material, through rational proportion, obtains hydrophobic sand by certain technical process with fine sand, toluene and polystyrene.
The technical problem to be solved in the present invention is solved by following scheme: a kind of is the method that hydrophobic sand prepared by raw material with waste polystyrene foam, it is characterized in that: waste polystyrene foam joined in toluene, forms the toluene solution of polystyrene; Add fine sand, stir, decompression and heating recovery toluene, namely obtain hydrophobic sand after discharging, naturally cooling, wherein the mass ratio of waste polystyrene foam, toluene and fine sand is 1:15-17:50-100.
Above-mentioned a kind of be that the waste polystyrene foam that raw material is prepared in the method for hydrophobic sand refers to: wrapping waste polystyrene foam and disposable lunch-box waste polystyrene foam etc. with waste polystyrene foam.
Advantage of the present invention is: the hydrophobic sand cost 1, prepared by this method is very low.2, sand surface is covered by polystyrene, thus not hydrophilic.3, be applied to urban afforestation or desertification control can save irrigation water, reduce evaporation with the process suppressing desertification, to reach the object of water saving and improvement desertification.4. a large amount of waste polystyrene foam that can effectively utilize city to produce, make rational use of resources and alleviate the pollution that discarded object causes.
Accompanying drawing explanation
Fig. 1 take waste polystyrene foam as the process chart that hydrophobic sand prepared by raw material.
