Description
Technical field
The present invention relates to ecological agriculture plastic applications more particularly to a kind of ecologic planting with nuisanceless light transmission film and its
Manufacturing method.
Background technology
Mulch, that is, covered ground film is typically transparent or black PE films, also has green, silver thin film, covered for ground
Lid to improve the soil moisture, keeps soil moisture, maintains soil texture, prevent pest attacks crop and certain micro-organisms from causing
Disease etc., promote the function of plant growth.
PE films are a kind of films translucent, glossy, quality is relatively soft in the prior art, have excellent chemical stabilization
Property, heat sealability, have that moisture resistance, penetrability are small, and freeze-resistant can boiling.But it can not almost be dropped due to poorly water-soluble and naturally
Solution, typically disposable as inexpensive heavy chemicals, a large amount of pollutions brought and nature are difficult to the white digested
Rubbish, and natural degradation of the prior art membrane process it is all relative complex or cost is huge, also can not be with inexpensive PE films shape
Into competition, market effect is bad.
Therefore, it is badly in need of the good life of extensive a kind of simple production process, raw material sources, easy natural degradation, applicability on the market
State plantation nuisanceless light transmission film and its manufacturing method.
The content of the invention
In view of the above defects of the prior art, the present invention is intended to provide a kind of simple production process, raw material sources
Extensively, the good ecologic planting of easy natural degradation, applicability nuisanceless light transmission film and its manufacturing method.
To achieve these goals, the present invention uses following technical scheme:A kind of nuisanceless light transmission film of ecologic planting
Manufacturing method, comprise the following steps:
1) prepare before production
1. raw material prepare:Prepare enough ethylene, prepare 3 parts -5 parts of niter cake, N-N ' methylene-bis- third by weight
2 parts of acrylamide, 3 parts -5 parts of hypericin;
2. auxiliary process material prepares:Prepare 3 parts -5 parts of magnesium chloride by weight, prepare enough Solute mass fractions 5%
Sodium-chloride water solution;
3. equipment and frock prepare:Prepare pressure vessel, reaction kettle, ultrasonic generator;
2) foamed plastics manufactures
1. by the stage 1) in the step niter cake, N-N ' methylene-bis-acrylamides and the stage 1 that 1. prepare) in step
2. the magnesium chloride prepared is uniformly mixed and is added in reaction kettle;
2. 1. reaction kettle that step is obtained is positioned in pressure vessel, the stage 1 is passed through in pressure vessel) in step 1.
The ethylene gas of preparation, until pressure 1.2MPa-1.5MPa in pressure vessel;
3. being warming up to 75 DEG C -80 DEG C, continue 4h-5h, obtain prefabricated material;
4. 3. prefabricated material that step is obtained is heated to molten condition, then the sodium-chloride water solution that step in 1) is 2. prepared
Being energized to makes its ionization, obtains plasma hydroxyl, applies in the prefabricated material that magnetic field makes hydroxyl injection molten condition, continues
Then 5min-8min steams the remaining moisture content brought from water vapour completely, complete the hydrophilic modification of prefabricated material, obtains hydrophiling
Prefabricated material;
5. the prefabricated material of 4. hydrophiling that step is obtained is heated to 150 DEG C -160 DEG C, then noted in the prefabricated material of hydrophiling
Enter the stage 1) in the hypericin that 1. prepares of step, using mechanical agitation, 15min-20min is kept the temperature after stirring evenly and is melted
Shape modified feedstock;
6. film is made in 5. molten modified feedstock that step obtains, the film be needed for ecologic planting with nuisanceless
Light transmission film.
Using the ecologic planting of above method manufacture with nuisanceless light transmission film, raw material include main material ethylene, gather
Close catalyst magnesium chloride, initiator niter cake, crosslinking agent N-N ' methylene-bis-acrylamides and modifying agent hypericin.
With existing Technical comparing, the present invention has the following advantages as a result of said program:(1) using ethylene as raw material, chlorine
Change magnesium is polymerization catalyst, niter cake is initiator, N-N ' methylene-bis-acrylamides are crosslinking agent and hypericin is to change
Property agent, is polymerized, use is inexpensive raw material that are nuisanceless, having extensive source, more under certain temperature and pressure
Add economic and environment-friendly.(2) inject hydroxyl after physics ionizes, be it is a kind of only can micro modification hydrophilicity-imparting treatment mode, it is conventional
Do not have to substantially in technology, the reason is that this modified effect is very limited, is generally only capable of organic matter becoming slightly soluble from indissoluble, but is used for
The present invention is most suitable, this is because present invention is generally directed to mulch material, since the use age of mulch is generally being sowed
Grow up to this period of adult to seedling, this is one not short period in fact, and hydrophily is excessively high to cause mulch to lose its use
Function;On the other hand, due to that can not possibly clean out when the present invention is withdrawn primarily directed to mulch, have part and be torn relic
It remains in soil, this part of mulch must have degradability, and not so accumulating over a long period will have endless trouble.(3) spun gold
Peach element is the extract of hypericum perforatum in fact, and antivirus action is generally used in routine techniques, but has grinding for many other fields
Study carefully when showing the composition as olefin polymer additive, also have the effect for being obviously improved polymer photosensitive, therefore it in fact
It is that luminous energy (in photochemical reaction, it is insensitive to visible ray to be transferred to some by a kind of not extensive photosensitizer of application in fact
To improve or expand the substance of its photosensitive property on reactant), in the present invention, its effect is dissociated under action of ultraviolet radiation
It into free radical, is melted and got together with PE main chains due to it, its solution defection drives PE backbone breakings, becomes from macromolecular
Into small molecule, it is well known that small organic molecule is more easy to be degraded by microorganisms or be absorbed by plants.
