Abstract
The invention discloses a method for preparing hydrophobic sand from fine sand, waste grease and waste plastic. The main technical process comprises the following steps: heating waste grease, adding waste plastic, heating to form a plastic ointment, adding fine sand and stirring while keeping the temperature so that the plastic ointment is uniformly distributed on the surface of the fine sand, and cooling to obtain the hydrophobic sand. The hydrophobic sand prepared by the method has favorable properties. By using the waste grease, waste plastic 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 preparation method who the present invention relates to can be used for city trees and shrubs, sand control and supply a kind of hydrophobic sand of other water saving fields application, referring in particular to waste grease, waste plastic and fine sand is the method that raw material prepares hydrophobic sand, hydrophobic sand refers to that the surface is covered by hydrophobic substance, and makes the not hydrophilic sand in surface.
Background technology
The present invention is primarily aimed at present shortage of water resources, irrigation water serious waste; Desertification is serious day by day, and waste grease and waste plastic etc. cause serious public hazards and do not have the problem of aspects such as utilization rationally.The fine sand that utilizes the very low fine sand of waste grease, waste plastic and cost to be covered by plastic waste for a kind of surface of feedstock production, because the surface of this sand is plastic waste, therefore can not keep moisture, and not hydrophilic, rainwater or irrigation water are permeated the ground smoothly; Because the fine sand surface is not hydrophilic, can effectively reduces moisture and absorb water with capillarity by soil simultaneously, and then evaporation causes the soil dehydration.
Because the present invention utilizes waste to be raw material, the hydrophobic sand of preparation is with low cost, yet there are no the relevant report of this aspect, and its particular performances will have broad application prospects it aspect desertification control and urban afforestation and beautification of landscape (if during preparation at the surface attachment different colours of sand).
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation method of hydrophobic sand, and this preparation method is raw material with fine sand, waste grease and plastic waste, through reasonable proportioning, makes hydrophobic sand by certain technological process.
The technical problem to be solved in the present invention is solved by following scheme: a kind of is the method for feedstock production hydrophobic sand with waste grease and waste plastic, it is characterized in that: waste grease is heated to 190 ℃-200 ℃, add waste plastic, stirring makes its fusing and mixes; Add fine sand down for 190 ℃-200 ℃ at heat tracing, in 190 ℃ of-200 ℃ of following heat tracings and stirring, the ointment that plastic waste and waste grease are formed evenly is attached to the fine sand surface, namely get hydrophobic sand behind the naturally cooling, wherein the mass ratio of waste grease, waste plastic and fine sand is 1:0.20-0.25:9-12.
Above-mentioned a kind of be that waste grease in the method for feedstock production hydrophobic sand refers to: discarded animal grease, discarded plant grease and sewer oil with waste grease and waste plastic.
Above-mentioned a kind of be that waste plastic in the method for feedstock production hydrophobic sand refers to: discarded polyethylene products, waste polyvinyl chloride goods and discarded polypropylene articles with waste grease and waste plastic.
Advantage of the present invention is: 1, very low with the husky cost of the hydrophobic of present method preparation.2, the sand surface is covered by very thin plastics-waste grease, thereby not hydrophilic.3, being applied to urban afforestation or desertification control can save irrigation water, reduce evaporation to suppress the process of desertification, to reach the purpose of water saving and improvement desertification.4. the waste plastic that can effectively utilize a large amount of waste greases that the city produces and town and country to produce is made rational use of resources and is alleviated the pollution that waste causes.
