Description
Technical field
The present invention relates to a kind of soil improvement material, particularly relate to hydrophobic modified grass planting spraying film materials of a kind of soil property and preparation method thereof.
Background technology
Ecological degeneration is the natural crisis that the current universe faces jointly, and wherein, grassland desertification and desertification have all dwindled human effective land use area greatly, and human existence has been caused threat.Grassland desertification and desertification chief reason are exactly that the face of land is hot dry because these geographic water resourcess lack, and evaporation capacity of moisture content is very big, and plant is not easy to survival.
The second in the world large fluidity desert with China---the Takla Makan Desert is an example, because its inland, depths has formed hot the arid desert climatope, the temperature difference is big, wind-force is powerful, and the sunshine duration is long, and arid is short of rain, atmospheric moisture is very low, and sand material is loose deep, and ground water table is darker.
In order to delay, in addition reverse grassland desertification and desertification constantly spread phenomenon, people are trying to explore various possible approach.But, in the face of these regional harsh climate conditions, people want to realize in these areas ecological recoveries effort always produce little effect.
In grassland desertification and desertification area, the key factor of realizing ecological recovery is a moisture condition, and at western China water resources famine exactly, quantity of precipitation only tens millimeters to the hundreds of millimeter, and the surface evaporation amount greatly (＞3000mm), poor water retention property makes ecological recovery become a difficult problem.How above-mentioned moisture loss being suppressed below the face of land, formed ventilative on the face of land but fluid-tight water conservation layer, thereby ecology is recovered, is a problem that is worth exploration.But how to obtain this ventilative but fluid-tight water conservation layer is a problem that waits to solve.
Summary of the invention
In order how to solve the problem that realizes ecological recovery in grassland desertification and desertification area, the invention provides the hydrophobic modified grass planting spraying film materials of a kind of soil property.
Technical scheme of the present invention is as follows:
The invention provides the hydrophobic modified grass planting spraying film materials of a kind of soil property, the parts by weight of the moiety that it comprises are as follows:
Soil property particle 850-1000;
Tensio-active agent 0.8-5;
Hydrophobic component 60-120.
As prioritization scheme, the hydrophobic modified grass planting spraying film materials of soil property provided by the present invention, the parts by weight of the moiety that comprises are as follows:
Soil property particle 900-920;
Tensio-active agent 2-3;
Hydrophobic component 80-100.
As prioritization scheme, the hydrophobic modified grass planting spraying film materials of soil property provided by the present invention also includes fertilizer 1-10 weight part.
Described tensio-active agent is meant the arbitrary combination of sodium laurylsulfonate, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate.
Described hydrophobic component is meant the arbitrary combination of soybean oil of rapeseed oil, the recovery of used oil, recovery.
The present invention also provides the preparation method of the hydrophobic modified grass planting spraying film materials of above-mentioned soil property, and step is as follows:
The tensio-active agent and the hydrophobic component of the described amount of above-mentioned prescription are mixed in the water, add described amount soil property particle behind the stirring and evenly mixing.Mixing is made mud.
The technique effect that the hydrophobic modified grass planting spraying film materials of soil property provided by the present invention is realized is as follows:
The hydrophobic modified grass planting spraying film materials of soil property is to be that matrix is made the soil property mortar with the soil property particle, cooperates the hydrophobic modified component with the tool hydrophobic nature, makes compound grass planting spraying film materials.In selection, why main component in the soil property mortar selects the soil property particle for use, mainly be because: (1) soil property particle is tiny, also there is certain space between layer and the layer, therefore specific surface area is big, and glassware for drinking water is had stronger adsorptivity, therefore can be used as a kind of water-keeping material, in addition, it can also adsorb extraneous water (as rainwater etc.); (2) the soil property particle also has widely distributed (take up an area of ball sedimentogeneous rock litre geosphere and weathering crust total amount near half), abundant, the lower-price characteristic in source; (3) can gather materials on the spot, directly simplify the preparation process of material, remove the trouble of bringing because of transportation of materials from.
Except the water retention property that utilizes the soil property particulate material, also need in mortar, to add hydrophobic modified component with strong hydrophobic nature, it contains has hydrophobic nature and oil loving group in a large number.The ground surface soil transpiring moisture mainly discharges the soil property internal moisture by the macrovoid between soil particle.Hydrophobic modified component will be coated on soil property particulate top layer, make the intergranular hydrophilic pores of soil property change the hydrophobic hole into and hinder water molecules, and it is difficult for from passing therebetween, thereby suppress the evaporation of desertificated area moisture.Because the soil property particle is a hydrophilic material, and hydrophobic modified component has strong hydrophobic nature, therefore in selection, also added tensio-active agent with parents' structure, utilize the special construction of this tensio-active agent that the hydrophobic end of soil property particulate water-wet side and hydrophobic material is combined togather firmly, make the hydrophobic component obtain good dispersiveness simultaneously.
The characteristics of this material are: (1) is hydrophobic modified by soil property, form the water conservation layer that one deck is ventilative, suppress moisture evaporation on surface, the desertification face of land, this water conservation layer can with in the soil property in a large number moisture evaporated suppress in the face of land, form one deck at place, the face of land and have certain thickness wet soil layer, this provides rational soil moisture for the herbaceous plant that is suitable for face of land growth; (2) have 75% to be the soil property particle in material is formed approximately, its wide material sources can be gathered materials on the spot.Therefore the material of main part for preparing the soil property mortar can be taken the on-the-spot veneer of soil of desertificated area, and this is just for realizing the field fabrication condition of providing convenience, thereby has saved the trouble of transportation, has saved manpower and materials simultaneously; (3) this material is implemented efficient height, easy handling by the technological method that sprays.The preparation of material only need mixing, slurrying and three steps of sprinkling, and technology is simple, and is easy and simple to handle.Do not need bulky equipment, only can finish the preparation of material by small and exquisite, the portable miniature instrument of some volumes.(4) hydrophilic component during material is formed is the soil property particle, and the hydrophobic component is a kind of trade waste, and is cheap, is easy to big area and promotes.(5) hydrophobic component---trade waste has passed through the removal of impurities of active carbon adsorption in advance and has handled, and objectionable constituent are removed, so this material non-toxic, and are harmless.(6) the hydrophobic component during material is formed is biodegradable, so it is a kind of environment friendly material.
