Abstract
The invention provides it is a kind of for agricultural planting can uniform dispenser biodegradable multilayer film, including mealy medicine, upper table facial mask and following table facial mask, the upper table facial mask and following table facial mask are made of the material modified blowings of PLA of different degradation rates, degradation rate of the degradation rate of following table facial mask higher than upper table facial mask, the dose according to needed for spraying area, mealy medicine even application is in the upper surface of following table facial mask, the hot pressing of upper table facial mask is on mealy medicine and following table facial mask, the present invention is designed faster using lower surface membrane degradation, middle mealy medicine can be promoted to be played a role in right times, avoid the inhomogeneities of artificial dispenser and reduce the cost of labor for repeating dispenser.
Description
Technical field
The present invention relates to biodegradable film class product, it is specifically related to one kind and is reached uniformly using PLA is material modified
The biodegradable multilayer film of dispenser.
Background technology
Biodegradable membrane-based article is widely used in various countries' agriculture field in forms such as mulch films, and PLA material is because needed for it
The recyclability of raw material, using the degradability of process, the nontoxic characteristic after degraded is widely used in medicine, bag
The fields such as dress, machine-building, agricultural, it is at present, required using traditional dispenser pattern for the crops dispenser of establishing in large scale
Artificial and machine cost is larger.China Patent No. is the 90107614.7 weeding tablets and capsule for disclosing paddy field application by throwing them, though
So solve the problems, such as that repetition dispenser and artificial mechanism cost are larger, but still it cannot be guaranteed that uniform dispenser, and dispenser environment is received
Limit.
The content of the invention
For Shortcomings in the prior art, the invention provides it is a kind of for agricultural planting can the biology of uniform dispenser can
Degraded multilayer film, realizes that middle mealy medicine uniformly plays a role using the difference of the degradation rate of upper and lower two membranes.
The present invention is to realize above-mentioned technical purpose by following technological means.
It is a kind of for agricultural planting can uniform dispenser biodegradable multilayer film, including mealy medicine, upper table facial mask and
Following table facial mask, the upper table facial mask and following table facial mask material modified are blown using the PLA (full name " PLA ") of different degradation rates
Modeling is made, the degradation rate of the degradation rate higher than upper table facial mask of following table facial mask, and the mealy medicine even application is in lower surface
The upper surface of film, the hot pressing of upper table facial mask is on mealy medicine and following table facial mask.
Preferably, it is by addition PBAT, modifying agent, antioxidant, plasticizer in PLA material that the PLA is material modified
Carry out material modification.
Preferably, the mealy medicine is weeding deinsectization medicine.
Beneficial effects of the present invention：
1) upper and lower surface film of the invention can according to demand using different degradation rates PLA it is material modified be made,
While meeting as mulch film or cultivate the use intensities such as bed, designed faster using lower surface membrane degradation, centre can be promoted
Mealy medicine plays a role in right times, it is to avoid the inhomogeneities of artificial dispenser and reduction repeat the cost of labor of dispenser；
2) for different crops, mealy medicine can select the suitable effective component of correspondence, reach deinsectization weeding ratio
Maximize.
Brief description of the drawings
Fig. 1 be it is of the present invention for agricultural planting can the uniform biodegradable multilayer film of dispenser structural representation.
Fig. 2 is the fractionation schematic diagram of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated, but protection scope of the present invention is simultaneously
Not limited to this.
With reference to Fig. 1 and Fig. 2, it is of the present invention it is a kind of for agricultural planting can uniform dispenser biodegradable multilayer
Film, including mealy medicine 1, upper table facial mask 2 and following table facial mask 3, the upper table facial mask 2 and following table facial mask 3 are using different degraded speed
The material modified blowing of the PLA of rate is made, the PLA it is material modified by added in PLA material PBAT, modifying agent, antioxidant,
Plasticizer carries out material modification, realizes the degradation rate of institute's masking product, and physical strength, water solubility rate is controllable.The powdery medicine
Agent 1 is to be dissolved in organic solvent such as toluene, second diones or alcohols by weeding deinsectization medicine, and adds anti-dispersant, antioxidant, breast
Change, oily matter of decentralized medium etc., are obtained after powdery is ground to form after then drying.The dose according to needed for spraying area, by powder
The even application of shape medicament 1 is covered on following table facial mask 3 in the upper surface of following table facial mask 3, upper table facial mask 2, and by the He of upper table facial mask 2
Following table facial mask 3 is hot pressed into an integral multi-layered film.
Instantly before skin covering of the surface 3 starts degraded breakage, the microdialysis of mealy medicine 1, drug effect is not obvious；Instantly skin covering of the surface 3 is opened
Begin after degraded breakage, middle mealy medicine coating 1 starts to penetrate into soil, and drug effect lifting reaches the uniform purpose from dispenser.
Due to the material of preparing present invention employs the material modified upper and lower surfaces as multilayer film of PLA, therefore the present invention
With stronger adaptability, to different geographical weather, soil, variety classes crop cycle has the suitable degraded of correspondence
Ability,
Preferred embodiment but the present invention is not limited to above-mentioned implementation method to the embodiment for of the invention, not
In the case of substance of the invention, any conspicuously improved, replacement that those skilled in the art can make
Or modification belongs to protection scope of the present invention.
