Description

A kind of agricultural insecticidal environmental protection oxygen barrier degradable plastic film
Technical field
The invention belongs to plastic film material field, especially a kind of agricultural insecticidal environmental protection oxygen barrier degradable plastic film.
Background technology
Along with food, medicine trade flourish, more urgent than ever to the demand of Novel oxygen insulation packaging material, exploitation is an important and urgent strategic task with the novel oxygen barrier material for food, Key works Drug packing of research.Current, packaging material problem of environmental pollution has caused the great attention of countries in the world, and the environment friendly realizing packaging material has become one of material science research most attraction and challenging direction.
Biodegradable plastic is one of effective way of administering plastic refuse environmental pollution and buffering petroleum resources contradiction, from the packaging bag of food to agricultural film, arrive the shell of electric equipment products again, from non-returnable container, edible products to product durable in use, biodegradable plastic just progressively replaces conventional plastic materials, and market prospects are very wide.It is reported, existing tens kinds of the biodegradable plastic kind of current global development, principal item has: the polyhydroxyalkanoate (PHA, PHB, PHBV etc.) of fermentable synthesis, the PLA (PLA), polycaprolactone, dihydroxylic alcohols dicarboxylic acids aliphatic polyester (PBS), aliphatic/aromatic copolyester, CO2/ epoxy compound composition copolymer (APC), polycaprolactone (PCL), polyvinyl alcohol (PVA) etc. of chemical synthesis, natural polymer starch plastics and biodegradable plastic blend, plastic alloy etc.The kind having entered pilot scale or batch production at present has starch plastics, PHA (PHB, PHBV, PHBH-HX etc.), PLA, PBS, APC, modified PVA, the starch/plastic alloy such as PVA, PLA, PCL and blend etc.
Starch is a kind of abundance, cheap natural macromolecular material, also be a kind of inexhaustible renewable resource, it can be biodegradable in a variety of environmental conditions, final catabolite CO2 and H2O can be recycled by the photosynthesis of plant, can not cause any pollution to environment.Therefore, starch is widely used in research and the product development of degradation plastic, and has achieved great progress.
At present, the domestic biodegradable packing film that have developed employing starch and prepared, pertinent literature report is more.Such as, Anlishan Green Environment Science & Technology Co., Ltd., Shenyang invention POL biodegradable plastic and preparation technology [CN1624034]; The biodegradable polypropylene carbonate composite material of one 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 application study in green pepper is fresh-keeping thereof, Li Jiezhi etc. the development of fruits and vegetables nano preservative film and the application study in green pepper is fresh-keeping thereof. Sichuan food and fermentation, 2008 (5): 28-31]; Fujian Province No.2 Light Industry Research Institute about the degraded LDPE packing film of starch/cerium stearate balanced constant research [Zhang Huaji. the research of the degraded LDPE packing film of starch/cerium stearate balanced constant. Chinese Plastics, 1999 (2): 60-65]; Institute of Hua Zhong Agriculture University is about the polyethylene/mechanical performance of mineral powder composite degradation film and the research [Wang Jinling of light degradation property, Yin Yeping, Deng. the mechanical performance of polyethylene/mineral powder composite degradation film and light degradation property. print during chemical industry, 2006 (3): 6-10].
Current starch plastic experienced by three generation products: the first generation product starch of 6% ~ 20% and the blend preparation of polyolefin (as PE, PP), belong to starch-filled plastic, the porous polymer staying the next one not degrade again after starch degradation and can not recycling.Its fragment causes more severe contamination to soil, so this kind of starch plastics is called as " false degradative plastics " or " disintegratable plastics ".Second generation product content be greater than 50% starch and hydrophilic polymer carry out blended preparation, stronger physics and chemistry effect is there is between starch and hydrophilic polymer, and exist with continuous phase, this material shows good biological degradability, machinability, economy, practicality, and Technical comparing is ripe.Third generation product is that thermoplastic starch, native starch, amylose or high amylose starches are not being added polymer, all biological degradation type plastic material that extrusion molding or injection moulding obtain under high temperature, high pressure and super-humid conditions, but is still in conceptual phase at present.
But adopt plastic package material prepared by starch at present, the size of biodegradability depends on the height of content of starch in system.The plastic film material that content of starch is high, although biodegradability is better, thin film material mechanics performance is short of, and film is barrier bad, when being used in the packaging field such as food, medicine, has a strong impact on the quality of packaging because of the gas permeability had in various degree.Therefore, development of new biodegradability is good, mechanical property can meet packaging instructions for use, have the attention that the packing plastics film of 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 agricultural insecticidal 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:
A kind of agricultural insecticidal environmental protection oxygen barrier degradable plastic film, it adopts to obtain at the double-coated insecticide of plastic sheeting; Its component and parts by weight are:
