Abstract

The invention relates to a composite for forestation, wind protection and sand fixation along the line of railway or highway. The composite is prepared by the following raw materials in proportion by weight: 50-95 parts of polystyrene, 15-50 parts of plasticizer, 60-150 parts of organic solvent, 5-25 parts of sodiumhydroxymethyl cellulose, 15-35 parts of dodecyl ammonium chloride, 100-300 parts of distilled water, 30-75 parts of gelantinizer, 3-20 parts of humectant and 0.002-0.03 part of photosensitive curing agent. The composite in the invention is diluted by adding water until the solid-containing amount in the composite is 1-10%, the diluted composite can be sprayed on soil and desert and then solidified to a ground film; and the composite takes the effect of preventing earth, fixing sand and preventing a large amount of water from evaporating, and has important sense for improving soil, managing sand, vegetating and foresting and improving ecological environment.

Description

Railway or the motorway composition and method of making the same of checking winds and fixing drifting sand of afforesting along the line

Technical field

The present invention relates to the technology method of forestation of arid biogeographic zone, especially a kind of railway or the motorway composition and method of making the same of checking winds and fixing drifting sand of afforesting along the line

Background technology

Railway in the desert or motorway are along the line in order to protect the unimpeded of railway or motorway; prevent the invasion and attack of dust storm; regulation will be planted trees; the method of conventional afforestation is to irrigate after plantation, and irrigation not only relates to the water source and also relates to problem of facility investment, labour and afforestation management or the like.About forestation without irrigation report is arranged also at present, but all do not mention the surrival rate of afforestation.In the qualification of quantity of precipitation, soil moisture, floristic selection, aspects such as planting technology and stability lack sufficient technical support.The restrictive factor that influences desert vegetation mainly is a moisture, and plantation of plant and growth be unable to do without moisture, particularly high temperature are being arranged, and the desert in arid summer is all the more so.Plant or bavin standing grain sand-protecting barrier is set if directly plant grass on the desert, effect is little, and a difficult problem that is run into is the lack of water and the fixing grains of sand.

Human have much in the sand control and the method for improving the soil, and contains a large amount of salts and acids in the some of them component, even also used chloroazotic acid, and not even a blade of grass grows can to make the desert as residual this type of material in the soil, and environment is caused secondary pollution.

Summary of the invention

Address the above problem, the purpose of this invention is to provide a kind of at railway or the motorway composition and method of making the same of checking winds and fixing drifting sand of afforesting along the line, said composition can spray the formation surface film, the surface film that forms has high temperature resistant and low temperature, water vapour transmission rate is low, and the soil on the face of land is not moved by wind, helps plant-growth, and degraded easily, can not produce secondary pollution.

Technical scheme of the present invention is: railway or the motorway composition of checking winds and fixing drifting sand of afforesting along the line, and said composition is formed by the feedstock production of following weight ratio:

Polystyrene 50-95 part, softening agent 15-50 part, organic solvent 60-150 part, sodium cellulose glycolate 5-25 part, dodecyl chlorination ammonium 15-35 part, distilled water 100-300 part, jelling agent 30-75 part, wetting Agent for Printing Inks 3-20 part, photo-curing agent 0.002-0.03 part.

Preferably, railway or the motorway composition of checking winds and fixing drifting sand of afforesting along the line, said composition is formed by the feedstock production of following weight ratio:

75 parts of polystyrene, 35 parts in softening agent, 100 parts of organic solvents, 15 parts of sodium cellulose glycolates, 25 parts of dodecyl chlorination ammoniums, 200 parts of distilled water, 50 parts of jelling agents, 10 parts of wetting Agent for Printing Inkss, 0.01 part of photo-curing agent.

Described softening agent is dibutyl phthalate, tributyl phosphate or triphenylphosphate.

Described organic solvent is dimethylbenzene, toluene or benzene.

Described wetting Agent for Printing Inks is glycol ether or sorbyl alcohol.

Described jelling agent is a V-Pyrol RC.

Described photo-curing agent is a α-Qing Jibingxisuanzhi.

Another object of the present invention provides a kind of railway or the motorway preparation of compositions method of checking winds and fixing drifting sand of afforesting along the line, it is characterized in that: may further comprise the steps:

Step 1. places No. 1 reactor to mix by weigh polystyrene 50-95 part and organic solvent 60-150 part of the weight part of above component, under 60-100 ℃ temperature, stirred 30 minutes, add softening agent 15-50 part again, stirred 30 minutes, obtain mixing solutions, standby;

Step 2. places reactor No. 2 with distilled water 100-300 part, adds sodium cellulose glycolate 5-25 part again, stirs and be warmed up to 60-90 ℃, be incubated after 30-40 minute, be cooled to 35-45 ℃, add dodecyl chlorination ammonium 15-35 part, continue to stir after 10-20 minute, obtain material A;

The material A that step 3. obtains jelling agent 30-75 part, wetting Agent for Printing Inks 3-20 part and step 2 joins in the mixing solutions of No. 1 reactor, and emulsification 1-2 hour, the photo-curing agent that adds 0.002-0.03 part made the afforestation of the present invention composition of checking winds and fixing drifting sand.

The invention has the beneficial effects as follows: owing to adopt technique scheme, the present invention has the following advantages:

1. the mulch film that composition of the present invention is consolidated into, (relative humidity is more than 95%) has the suction water-permeable when descending rain and dew, rain and dew are permeated the ground, mulch film itself is then water insoluble, and when drying (relative humidity is 0-95%), underground steam is had gas barrier, and (the steam transmitance has only 1.4gH ₂ O/ ㎡/24h), like this, when the mixed solution of inventing sprays in the desert form mulching, the spontaneous evaporation amount that just can suppress desert moisture greatly, simultaneously, many chemical group grains of sand in the mulch film have the absorption keying action of various ways and the grains of sand are lost flowability, and plant seed at this point film can be avoided being blown away or burying by wind under covering.

But composition of the present invention manpower, motor-driven or plant seeds by airplane behind thin up spray, and be simple and easy to do, imposes on the desert and then can play sand-fixing effect rapidly, and plant seeds by airplane can be administered 20,000 mu/day in desert by ten sorties that fly every day, and efficient is considerable.Especially on dust storm mouth or sand dune, the superiority of this composition more can be brought into play in the place that general solid film is difficult to use.

Composition thin up of the present invention to solid content is can spray behind the 1-10% to be suitable for soil, desert, form mulching, play and protect soil, fix the sand and prevent the effects of a large amount of evaporations of moisture, to improve the soil, administer desert, vegetation afforestation, improve the ecological environment significant.
