Description
Technical field
The present invention relates to field of agricultural irrigation, and in particular to a kind of agricultural irrigation soakaway trench and preparation method thereof.
Background technology
China is large agricultural country, and annual irrigation water needs to expend substantial amounts of water resource, but China is a water again
The country of resource famine, water resources ownership per capita just correspond to a quarter of world occupancy volume per person, therefore, adopt
The irrigation method of water saving is significant for China's agricultural production.In many irrigation methods, infiltrating irrigation is considered as
Water-saving result is best, a kind of irrigation method best to crop growth.Made using rubber pange technique more than infiltrating irrigation pipe, should
In technique, if frothing percentage is low, the water seepage hole of formation is less, it is impossible to meet infiltrating irrigation requirement, if frothing percentage is high, the mechanical strength of body
It is low, not even easy-formation, and easily make mud particles result in blockage into water seepage hole, cause its service life not long, need
Frequently change, increase agriculture production cost.
The content of the invention
The purpose of the present invention is, for above present situation, there is provided a kind of infiltrating irrigation effect is good, be not easily blocked, long service life and
The agricultural irrigation soakaway trench of low cost, and the preparation method of the soakaway trench is provided.
The technical solution used in the present invention：
A kind of agricultural irrigation soakaway trench, which includes soakaway trench main body and the filter cloth being coated on outside the soakaway trench main body；
The soakaway trench main body includes the component of following mass ratio：Random polypropylene：Polychlorostyrene second：Polyethylene alkene=85-90：3-8：3-8,
The filter cloth includes the component of following mass percent：Polyethylene terephthalate 65%-75%, isotactic polypropylene 25%-35%.
Preferably, the soakaway trench main body includes the component of following mass ratio：Random polypropylene：Polrvinyl chloride：Polyethylene=
90：5：5, the filter cloth includes the component of following mass percent：Polyethylene terephthalate 70%, isotactic polypropylene 30%.
Preferably, the polyethylene is linear low density polyethylene (LLDPE).
Preferably, the weight per unit area of the filter cloth is 20g/m2, which is coated on the number of plies outside the soakaway trench main body
For 4 layers.
Present invention also offers the preparation method of above-mentioned agricultural irrigation soakaway trench, its step is as follows：
（1）Random polypropylene, polrvinyl chloride and polyethylene are weighed by the mass percent, stirring is equal in adding blender
It is even；
（2）The material for stirring is put in kneader, the colorant and plasticizer of convention amount is added, is stirred；
（3）By pelletize in kneaded material input comminutor；
（4）The granule made is put in extruder and is extruded into tubing；
（5）Punch on tubing wall, aperture 0.09mm, water permeable area 2250mm2/m；
（6）The polyethylene terephthalate and isotactic polypropylene of the mass percent are taken, according to conventional blended weave
Blending, makes filter cloth；
（7）The filter cloth is coated on outside the tubing, the agricultural irrigation soakaway trench is obtained final product.
In soakaway trench of the present invention, it is used as soakaway trench main body by selecting random polypropylene and polrvinyl chloride, polyethylene composition
Raw material, due in random polypropylene molecule side chain it is out of order be arranged in the both sides of molecular backbone, itself and polrvinyl chloride and poly- second
The interaction force produced between alkene molecule is also just relatively mixed and disorderly, can make soakaway trench main body using simple preparation technology
With excellent mechanical performance, the indeformable rupture of larger pressure can be born.Wherein when the type of polyethylene is low close from line style
During degree polyethylene, can make soakaway trench that there is more excellent crushing resistance.By in soakaway trench main body outer cladding filter cloth, not affecting infiltrating irrigation to imitate
Really, and water seepage hole can be avoided from being blocked by mud particles, and impact of the hydrotaxis of effectively solving crop root system to soakaway trench,
Make the service life of soakaway trench of the present invention up to 40-50, the wherein weight per unit area of filter cloth is 20g/m2, cladding the number of plies
For 4 layers when, preferably, operating cost is minimum for infiltrating irrigation effect, and per mu of infiltrating irrigation water consumption is 25 cubes or so, is that common flood overflows
Fill the 1/4 of water consumption, the 1/3, the 1/2 of drip-irrigation water amount of water consumption of spraying, can saving water resource in a large number, while can also save greatly
Amount electric power energy, brings huge economic and social benefit.The preparation method of soakaway trench of the present invention is simple, relatively some infiltrations at present
The preparation method raw material of pipe is easy to get, simple to operate, and more existing infiltration tube lifetime is longer for obtained product quality, and effect is more
It is excellent.
