Description
Specification digest
It is an object of the invention to provide it is a kind of can blown film Biodegradable resin and preparation method thereof.According to the life of this method
The degraded plastic packaging film of production, can fundamentally solve packaging material after having used, and be discarded in the Nature or heap is embedded in
In rubbish, carbon dioxide and water etc. can be completely broken down within the 3 months time to half a year, is that one kind is beneficial to plant growth
Material fully biodegradable packaging material.Another object of the present invention is to can solve the problem that substitution petroleum resource consumption
The problem of.The biodegradable material is full biomaterial, without 4P（That is PE, PP, PVC, PS）It is a kind of brand-new
Biodegradation material, can effectively substitute petroleum resources.The whole world every year be used for packaging material on polyolefine material number with
Hundreds of millions tons of meters, are all that oil product cracking is obtained.The packaging material that we successfully manufacture starch base, in oil price not
Break when riseing, will save bulk petroleum resource for country every year.
Technical field
The present invention relates to packaging material, and in particular to it is a kind of can blown film Biodegradable resin and preparation method thereof.
Background technology
It is well known that petroleum resources are increasingly in short supply now, oil price constantly rises, and gives people daily life, work and brings
Many harmful effects, have had a strong impact on the development speed of social economy, are also the factor leading to social instability of contention for resource between area.
For a long time, plastic sheeting based article used in us is all to use oil synthetic resin, such as polyvinyl chloride, poly- second
The disposable film class manufactured goods that the materials such as alkene are made, go out of use after being finished as rubbish, 200 years or so ability quilts of this rubbish need
Decompose, therefore being abandoned everywhere of having, cause harm very big " white pollution ", have by heap buried or burn, great wave
The petroleum resources that could be formed for more than one hundred million years are taken, it is direct to produce harmful substance during plastic sheeting based article is thrown aside in processing
Air or water source are polluted, due to the non-degradable characteristic of petrochemical industry plastics, its plastic damage remained soil texture makes many good
The field underproduction, soil sandification, river is blocked, and causes flood.
In recent years, the harm that solution " white pollution " is produced to the mankind is just mentioned in schedule discussion by many national governments,
Cry more and more higher, various countries have put into substantial amounts of financial resource and material resource in succession, and have taken out corresponding control measures, but effect is failed to understand
It is aobvious." white pollution " is constantly breaking ring our natural environments for depending on for existence, and the trying every possible means of the whole world effort is administered
Or eliminate the harm that " white pollution " is brought.The applicant for these reasons, a variety of drop was proposed by research and development
The production method of biological resin material is solved, the present invention is exactly that the present inventor is based on the basis of conventional scheme, is carried by improving
Go out it is a kind of can blown film Biodegradable resin and preparation method thereof.
The content of the invention
It is a kind of can blown film Biodegradable resin and preparation method thereof, it is characterised in that：The preparation method of the material includes
Following steps：
First, raw material is prepared according to following percentage by weight：
PLA 30-50%
Starch 5-25%
Biodegradable polyester 40-60%
Plasticizer 0.1-0.5%
Filler 1-5%
Compatilizer 0.5-2.5%
2nd, PLA, starch, Biodegradable polyester, plasticizer, filler, compatilizer are added in high-speed mixer, stirring is equal
It is even；
3rd, above-mentioned well mixed raw material is put into comminutor kneaded, melted, being extruded, cool down after pelletizing, prepare biological
Degradative resin；
The starch is cornstarch, tapioca, one kind of farina or its mixture；
Described Biodegradable polyester is：It is poly butylene succinate, poly-succinic-adipic acid-butanediol copolymer, poly- to benzene
One kind in dioctyl phthalate-adipic acid-butanediol copolymer, polycaprolactone, poly butyric-hydroxypentanoic acid copolyesters or other are mixed
Compound；
Described plasticizer is glycerine, sorbierite, one kind of ATBC or its mixture.
Described filler is calcium carbonate, talcum powder, one kind of montmorillonite or its mixture.
Described compatilizer is ethylene-methacrylic acid copolymer, ethylene-acrylic acid copolymer, ethylene-vinyl acetate
One kind of copolymer or its mixture.
The advantage of the production method of the present invention is that technique is simple, and various raw materials are mixed using one-step method, pass through twin-screw
Extruder is granulated, and made resin is processed into film by film blowing device.
Degradation property of the present invention is excellent, can it is degradable, environmentally safe, non-toxic, will not soil texture produce it is broken
It is bad.
In addition, its simple production process, cost are low, combination property is preferable.
The following is the specific embodiment of the present invention：
Embodiment one：
PLA 35%, cornstarch 10%, poly butylene succinate 50%, glycerine 0.5%, calcium carbonate 2.5%, ethene-
Acrylic copolymer 2%
Embodiment two：
PLA 40%, tapioca 15%, poly terephthalic acid-adipic acid-butanediol copolymer 40%, sorbierite 1%, illiteracy
De- soil 3%, ethylene-methacrylic acid copolymer 1%
Double screw extruder is employed in the comminutor of the present invention, will be cooling extruded using water-cooling pattern in described comminutor
Billot is melted, wherein, processing temperature is 180 DEG C, and screw speed is 150rpm.Ultimogenitary biodegradable resin particle rule
Lattice are：Granularity is φ 2-3mm, and length is 3-4mm, cylindrical particle.
