Abstract
The invention relates to an environment-friendly oxygen-proof degradable plastic film which comprises the following components in parts by weight: 40-60 parts of corn starch, 100 parts of low-density polyethylene (LDPE), 20-40 parts of Pulullan polysaccharides, 10-20 parts of polycarbonate, 2-4 parts of an antioxidant, 0.5-1 part of an ultraviolet absorbent, 4.5-6.5 parts of cedar wood oil and 5-10 parts of polyethylene wax. The oxygen-proof degradable plastic film provided by the invention can be automatically decomposed under the effect of rich oxygen and microorganisms, and the discarded film can be completely degraded and digested by the microorganisms in the nature to finally generate carbon dioxide and water; compared with an LDPE film with the same thickness, the oxygen-proof performance can be improved by 40%. A preparation method of the oxygen-proof degradable plastic film is simple in process, high in production efficiency and easy to industrially implement; the oxygen-proof degradable plastic film can be produced through a general plastic film blowing machine.
Description
Technical field
The invention belongs to plastic film material field, especially a kind of environmental protection oxygen barrier degradable plastic film.
Background technology
Flourish along with food, medicine trade, more more urgent than in the past to the demand of Novel oxygen insulation wrapping material, exploitation and the novel oxygen barrier material for food, drug packaging of research are important and urgent strategic tasks.Current, wrapping material problem of environmental pollution has caused the great attention of countries in the world, and the environment friendly of realizing wrapping material has become one of the most attractive and challenging direction of Materials science research.
Biodegradable plastic is one of effective way of administering plastic refuse environmental pollution and buffering petroleum resources contradiction, from the packing bag of food to agricultural film, arrive again the shell of electric equipment products, from non-returnable container, edible products to product durable in use, biodegradable plastic just progressively replaces conventional plastic material, and market outlook are very wide.It is reported, the biodegradable plastic kind of global development is existing tens kinds at present, principal item has: the microorganism synthetic polyhydroxyalkanoate (PHA, PHB, PHBV etc.) that ferments, the poly(lactic acid) of chemosynthesis (PLA), polycaprolactone, dibasic alcohol dicarboxylic acid aliphatic polyester (PBS), aliphatic/aromatic copolyester, CO2/ epoxy compound composition copolymer (APC), polycaprolactone (PCL), polyvinyl alcohol (PVA) etc., natural polymer starch plastics and biodegradable plastic blend, polyblend etc.The kind that has entered at present pilot scale or batch production has starch plastics, PHA (PHB, PHBV, PHBH-HX etc.), PLA, PBS, APC, modified PVA, starch/PVA, the polyblends such as PLA, PCL and blend etc.
Starch is a kind of abundant, cheap natural macromolecular material of originating, also be a kind of inexhaustible renewable resources, it can be biodegradable under multiple envrionment conditions, final degraded product CO2 and H2O can carry out recirculation by the photosynthesis of plant, can not cause any pollution to environment.Therefore, starch is widely used in research and the product development of degradable plastics, and has obtained great progress.
At present, the domestic biodegradable packaging film that adopts starch to prepare of having developed, pertinent literature report is more.For example, POL biodegradable plastic and the preparation technology [CN1624034] thereof of Anlishan Green Environment Science & Technology Co., Ltd., Shenyang's invention; A kind of biodegradable polypropylene carbonate composite material of CNOOC's invention and preparation method thereof [CN101962470]; The poly lactic acid nano composite material of a kind of complete biodegradable of Changchun Applied Chemistry Research Inst., Chinese Academy of Sciences's invention and preparation method thereof [CN101735583]; Sichuan Food Fermentative Industry Design Academy is about the development of fruits and vegetables nano preservative film and [the remaining Wenhua of the applied research in green pepper is fresh-keeping thereof, Li Jiezhi etc. the development of fruits and vegetables nano preservative film and the applied research in green pepper is fresh-keeping thereof. Sichuan food and fermentation, 2008 (5): 28-31]; Fujian Province industries under Ministry of the Second Light Industry institute about starch/cerium stearate coordinate the degraded LDPE packaging film of system research [Zhang Huaji. starch/cerium stearate coordinates the research of the degraded LDPE packaging film of system. Chinese Plastics, 1999 (2): 60-65]; Institute of Hua Zhong Agriculture University is about the mechanical property of polyethylene/mineral powder composite degradation film and the research [Wang Jinling of light degradation property, Yin Yeping, Deng. mechanical property and the light degradation property of polyethylene/mineral powder composite degradation film. during chemical industry, print 2006 (3): 6-10].
Current starch plastic has experienced three generation products: the blend preparation of 6%～20% starch and polyolefine (as PE, PP) for first-generation product, belong to starch-filled plastic, after starch degradation, stay the porous polymer that the next one can not degrade again and can not recycle.Its fragment causes more severe contamination to soil, so these kind of starch base plastics are called as " false degradative plastics " or " disintegratable plastics ".S-generation product is greater than 50% starch and hydrophilic polymer with content and carries out blend preparation, between starch and hydrophilic polymer, there is stronger physics and chemistry effect, and exist with external phase, this material has shown good biological degradability, workability, economy, practicality, technology comparative maturity.Third generation product is that thermoplastic starch, native starch, amylose starch or high amylose starch are not being added to polymkeric substance, all biological degradation type plastic material that extrusion molding or injection moulding obtain under high temperature, high pressure and super-humid conditions, but at present still in conceptual phase.
But, the Plastic Packaging Materials that adopts at present starch to prepare, the size of biodegradability depends on the height of starch content in system.The plastic film material that starch content is high, although biodegradability is better, thin film material mechanics performance shortcoming, and film oxygen barrier is bad, while being used in the packaging fields such as food, medicine, has a strong impact on the quality of packing because having ventilation property in various degree.Therefore the attention that, good, the mechanical property of development of new biodegradability can meet packing service requirements, the packing plastics film with good oxygen barrier is subject to countries in the world height.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of a kind of environmental protection oxygen barrier degradable plastic film with more superior tensile property and elongation at break is provided.
The technical scheme that the present invention realizes object is:
An environmental protection oxygen barrier degradable plastic film, its component and parts by weight are:
And described oxidation inhibitor is antioxidant 1010 or irgasfos 168.
And described UV light absorber is salol or ultraviolet absorbent UV-531.
And described polyethylene is that Low Density Polyethylene, medium-density polyethylene, high density polyethylene(HDPE) are according to mass ratio 2:2:1 batch mixing.
Advantage of the present invention and beneficial effect are:
Oxygen barrier provided by the invention and degradable plastic film be meeting automatic classifying under the effect of oxygen enrichment and microorganism, film after discarded can be by the degradable digestion of occurring in nature microorganism, final carbonic acid gas and the water of generating, can improve 40% compared with the ldpe film oxygen barrier performance of same thickness.Preparation method's technique of the present invention is simple, production efficiency is high, industrializing implementation is easy, available common plastics inflation film manufacturing machine is produced.
