Description
Technical field
The invention belongs to agricultural irrigation equipment technical field, especially relate to a kind of drip irrigation pipe, more particularly relate to one kind
Protection against rodents type drip irrigation below the surface pipe and preparation method thereof.
Background technology
Drip irrigation is one of the most efficient fertilizer irrigation technology of field irrigation so far, can accomplish little water frequent irrigation, make moisture
Slow equably infiltration soil, can play holding effect, and form the suitable soil water, fertilizer, thermal environment to Soil structure.Buried
Formula drip irrigation technique has obvious water-saving result, has many advantages, such as following: 1, douche is embedded in below earth's surface, will not produce ground
Table runoff, reduces the water content of topsoil to greatest extent, decreases Evaporation among plants loss；2nd, hollow billet and douche be successively
Embedment underground can be using for many years, it is to avoid under-film drip irrigation is annual to lay and reclaim the trouble of drip irrigation zone and because caused by reclaiming
Arm, auxiliary pipe and pipe fitting failure loss；3rd, reduce weed growth, underground drip irrigation make earth's surface relatively dry it is suppressed that weeds send out
Bud and growth；4th, do not destroy Soil structure；5th, utilization rate of fertilizer is high, applies underground drip irrigation technique, can be in the crop time of infertility
Interior, timely and appropriate discovery nutrient and pesticide accurately and are directly delivered to crop root zone；6th, underground drip irrigation douche is moistened
Region be spherical, compare with drip surface, the volume of its humid region and surface area all greatly increase, be as root system hypertrophy expand
Dissipate, absorb nutrition and provide bigger space.
But, in storage and Field information, drip irrigation pipe can suffer that muroid is destroyed, muroid relies primarily on vision, audition, taste
Feel to experience surrounding with olfactory sensation.There is the report adding capsaicin in drip irrigation pipe, because capsaicin is had in prior art
Standby pungent has zest, and it enables to the oral mucosa of muroid and taste nerve is subject to intense stimulus to detest and reject and chew
Cut, and so that muroid is abandoned biting and distribute the drip irrigation pipe of same abnormal smells from the patient, thus reach walking quickly and keeping away effect.
But, drip irrigation pipe is permanent use after, muroid has adapted to the abnormal smells from the patient of capsaicin or capsaicin composition due to moving forward to
Extraneous and content reduces, protection against rodents decreased effectiveness will be led to, walk quickly and keep away effect and reduce.
Content of the invention
The problem to be solved in the present invention is for above-mentioned deficiency, provides that a kind of protection against rodents effect is more preferable, action time is more longlasting
Protection against rodents type drip irrigation below the surface pipe and preparation method thereof.
For solving above-mentioned technical problem, first purpose of the present invention is to provide a kind of protection against rodents type drip irrigation below the surface pipe, adopts
Technical scheme is:
A kind of protection against rodents type drip irrigation below the surface pipe, described drip irrigation pipe is to be prepared by each component including following mass fraction
: the high density polyethylene (HDPE) of 40-60%, the Low Density Polyethylene of 10-30%, the linear low density polyethylene of 10-30%, 1-
10% protection against rodents master batch, the multifunctional concentrate of 1-2%, described protection against rodents master batch is by the raw material system including Ratproof agent a and Ratproof agent b
For obtain, wherein, Ratproof agent a is ethyl cellulose microcapsule encapsulation capsaicin granule, and b is cinnamamide.
Further, described ethyl cellulose microcapsule encapsulation capsaicin granule is prepared by the following method and obtains:
(1) ethyl cellulose is added and in organic solvent, form solution c；(2) capsaicin nano-powder is added in solution c, then plus
Enter emulsifying agent, form emulsion d；(3) emulsion d is added in deionized water and agitating heating, evaporation of organic solvent, by gained
Product filter, washing, be dried after obtain ethyl cellulose microcapsule encapsulation capsaicin granule.
As preferred scheme, described organic solvent is dichloromethane.
Further, described protection against rodents master batch is prepared via a method which to obtain: weight fraction is anti-for 10-30%
The Ratproof agent b of Mus agent a, 1-10%, the Low Density Polyethylene of 40-70%, the antioxidant of 1-3%, the ethylene vinyl acetate second of 10-20%
After alkene ester mix homogeneously, heated plasticizing, extrusion, sizing, cooling, pelletizing, air-dry make.
Further, described multifunctional concentrate is fluoropolymer additive ppa.
Further, the wall thickness of described drip irrigation pipe is more than or equal to 0.4mm.
Second object of the present invention is the preparation method providing protection against rodents type drip irrigation below the surface pipe, using following technical side
Case:
Add after high density polyethylene (HDPE), Low Density Polyethylene, linear low density polyethylene and multifunctional concentrate are mixed and squeeze
Go out in machine；Protection against rodents master batch adds in little co-extrusion machine；Preheat at a temperature of 200-260 DEG C, through former in 260-280 DEG C of temperature
Under, major ingredient and protection against rodents master batch co-extrusion obtain drip irrigation pipe.
Further, drip irrigation pipe preparation adopts co-extrusion technology, and protection against rodents composition is passed through co-extrusion machine and is present in droplet with vitta form
Fill in pipe.
The present invention has the advantages and positive effects that:
1st, capsaicin is carried out micro encapsulation, ethyl cellulose is used as wall material, using its good moulding property with dredge
Aqueouss, it is to avoid drip irrigation pipe is chronically in moist environment and causes protection against rodents composition to be affected by biological in soil, chemistry, physical environment
And reduce protection against rodents effect；
2nd, the cinnamamide adding can cause muroid dyspepsia, plays secondary avoidance effect by trained reflex；
3rd, production technology adopts co-extrusion technology, by protection against rodents composition presented in vitta in drip irrigation pipe, it is to avoid giving birth to
During product, cooling water is taken away the protection against rodents composition being scattered in drip irrigation pipe surface and is caused surface protection against rodents constituent reduction, penetrating odor
Reduce.
