Description
Technical field
The present invention relates to plastics technical field of membrane, and in particular to a kind of degredation plastic film.This plastic foil has with leading to
With the performance that plastic foil is similar, and can degrade under certain environment.
Background technology
Plastic foil is using thin made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other thermoplastic resins
Film, for packing, and as coating layer.Commercially shared share is increasing for plastics package and plastic packet product,
Particularly composite plastic flexible package, has been widely used for the fields such as food, medicine, chemical industry, wherein again with packaging for foodstuff institute
Accounting example is maximum, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products are all given
People's life brings great convenience.
Although plastic foil has brought great benefit, but with the use of plastic foil, to people life and
Environment brings many problems, and very big pollution is particularly caused to environment.This is all due to that plastic foil can not be timely
Caused by degraded.Even if plastic foil has suitable negative effect, but can not be given up at present, it is therefore desirable to develops energy
The plastic foil enough degraded, so as to which on the premise of plastic foil is widely used, it is negative to reduce the pollution that plastic foil is brought etc. as much as possible
Face is rung.
The content of the invention
The purpose of the present invention is to solve the above problem, there is provided a kind of degredation plastic film.
The plastic foil of the present invention possesses with other by the similar performance of plastic foil prepared by general-purpose plastics, still, this hair
Bright plastic foil can degrade under certain environment, so that reduce plastic foil widely uses the environmental pollution brought.
In order to reach foregoing invention purpose, the present invention uses following technical scheme:
A kind of degredation plastic film, the plastic foil by weight percentage, including thermoplastic resin 66.7% ~ 71.8%, cerium
0.2% ~ 0.5%, lanthanum 0.3% ~ 0.6%, samarium 0.8% ~ 1.2%, lutetium 0.4% ~ 0.7%, thick scandium powder 7.6% ~ 9.1% and starch 16.5% ~
23.2%。
The degraded of current plastic foil operates:In plastic packing product(Plastic foil)Production process in add it is a certain amount of
Additive(Such as starch, modified starch or other celluloses, photosensitizer, biodegradation agent), make the stabilization of plastic packing article
Property decline, be easier to degrade in natural environment, still, make plastic foil degradation effect bad by adding starch at present, utilize
Biodegradable principle added in resin starch year may be degraded, but degrade cycle it is longer.
The invention using key component of the starch as degraded, and while starch is added, add and aid in
Compounding agent samarium, for improving the structure of material, so as to structurally alter the solution speed of plastics, accelerate plastic degradation;Match somebody with somebody
Mixture lutetium, for catalyst article, catalytic action, accelerated degradation are produced to degraded;Compounding agent scandium, not only can be with decomposition plastics, together
When can be used as half initiator, enable plastics Auto-decomposition, so as to accelerate degradation speed;Starch, is helped as main degraded
Agent, the degraded to plastics produce facilitation.
Preferably, the starch is modified starch.
Preferably, the thermoplastic resin is polyvinyl chloride, polyethylene, polypropylene, polystyrene.
Preferably, the thermoplastic resin is polyethylene.
Preferably, the plastic foil by weight percentage, including polyethylene 68.7% ~ 70.1%, cerium 0.2% ~ 0.5%, lanthanum

The purpose for adding hydrazine hydrate and tetraphenyltin is in order to change the structure of resin, to thin from structure and in crystallization
Film is improved, can be in follow-up degradation process, and degradation reaction and degradation rate are rapider.And pass through addition
The two, can be controlled the useful life of film, make its degradation process more controllable, can more easily control film
Service life.The degradation rate in degradation process can be adjusted by hydrazine hydrate and tetraphenyltin, so as to effectively making
It is balanced with service life and degraded.
Preferably, the content of scandium element is 0.3%-3% in the thick scandium powder.
Compared with prior art, the present invention beneficial effect is:
Absorption of the plastic foil of the present invention to light is preferable, has the photopermeability than general plastic foil higher;
The plastic foil of the present invention starts to degrade after can exceeding service life under field conditions (factors), and within certain period by high score
Sub- weight polymers are reduced to oligomer, until that will not form adverse effect to environment, so as to reduce the harm to environment.
