Description
Technical field
The present invention relates to environmental organism degradation shopping bag thin film materials arts, and in particular to a kind of environmental organism degradation shopping
Bag and preparation method thereof.
Background technique
The features such as plastics are with its safety, health, lightweight, durable and high article packaging ratio, becomes the main of shopping bag
Material.Common shopping bag makes of polyethylene, it is very difficult to degrade.And most of second of the purposes of shopping bag is refuse bag.Dress
For the plastic shopping bag of full rubbish in addition to part carries out burning disposal, remaining is transported to landfill yard.It is close because of common plastics shopping bag
Sealing property is good, and the shopping bag equipped with rubbish prevents exchanging for empty gas and water inside and outside bag and microorganism, reduces the degradation of rubbish
Rate.In addition, the gas wrapped up in shopping bag is not easy to discharge, thus plastic membrane product is considerably increased in garbage loading embeading
The volume that place accounts for causes the percentage of plastics package rubbish volume shared by landfill yard to be far longer than its weight percent.It is general
Logical shopping bag can not degrade, and compost type biodegrade shopping bag is degraded quickly under compost state, but in normal circumstances, especially
It is to degrade slowly in dry environment.According to the purposes of shopping bag, other than being able to satisfy shopping and needing, shopping bag degradability of degrading
Energy index is: can degrade in conventional environment and degrade in refuse landfill.
Summary of the invention
For existing shopping bag problem difficult to degrade, the present invention is added to the starch of certain fineness, so that shopping bag is being filled out
After burying a period of time, it is capable of forming the aperture of gas permeability, accelerates the environmental organism degraded in refuse landfill degradation shopping
Bag and preparation method thereof.
The technical solution adopted in the present invention is as follows:
A kind of environmental organism degradation shopping bag, the shopping bag material includes the raw material of following weight percent: 5%~20% forms sediment
Powder, 0.1%~0.5% 3 oleoyl isopropyl titanate, 0.02%~2% degradation of promoter, 2%~4% glyceryl triacetate and 73.5%
~92% biodegradable polymers.
When the shopping bag of production is with a thickness of 25 microns, starch crosses the sieve of 600 mesh, and tailing over is 0~5%, again by screenings
The sieve for crossing 800 mesh, tailing over is 5%~30%；
When the shopping bag of production is with a thickness of 30 microns, starch crosses 500 mesh sieve, and tailing over is 0~5%, by screenings after 600
Mesh sieve, tailing over is 5%~30%.
Further, the degradation of promoter is copper compound, iron compound, titanium compound, cerium compound, cobalt chemical combination
One of object, lanthanum compound and praseodymium compound.
Further, the biodegradable polymers are aliphatic-aromatic copolymer, aliphatic polyester, titanium dioxide
Carbon-one of epoxy compound composition copolymer and oxygen-containing polyalkamer.
Further, a kind of preparation method of environmental organism degradation shopping bag, by load weighted starch, three oleoyl metatitanic acids
Isopropyl ester and degradation of promoter, which are put into heating stirring machine, is stirred 5~7min of mixing, after it is again that load weighted triacetic acid is sweet
Grease and biodegradable polymers mixing are put into heating stirring machine, continue to be stirred together for 5~7min of mixing；
Mixture is granulated using twin-screw extruder pelletizer, prepares pellet, pellet is poured into single screw rod and squeezes out inflation film manufacturing machine
Middle blown film prepares shopping bag film；Shopping bag is made in shopping bag film with Bag Making Machine.
Further, the revolving speed of the heating stirring machine be 1000 ~ 1200rpm, 50 DEG C ~ 60 DEG C of whipping temp.
Further, the screw slenderness ratio L/D of the twin-screw extruder pelletizer is 40 ~ 50, and pelletization stage temperature is 140
℃~175℃。
Further, it is 30 that the single screw rod, which squeezes out the screw slenderness ratio L/D of inflation film manufacturing machine, blown film phase temperature is 145 DEG C ~
175℃。
Percentage composition in the present invention is weight percentage.
Described tail over is to stay in the percentage composition of the substance above sieve, screenings is logical during sieve sieve
The substance that sieve of sifting out down.
Beneficial effects of the present invention:
The present invention passes through the starch of addition different-grain diameter, so that after biodegradable shopping bag meets the primary demand of shopping, quilt
When as refuse bag, the hole of small size can be first generated, is gradually degraded later under the action of the light in soot or heat.
The generation of shopping bag hole, oxygen enters inside shopping bag in environment, accelerates the decomposition of rubbish in bag, to reduce rubbish body
Product, extends the service life in soot.Biological degradability also makes shopping bag and rubbish degrade together, is further reduced its volume.
If abandoned is in the environment of dry water shortage, also light and heat oxidative degradation can occur, finally produce under the action of degradation of promoter
Object is carbon dioxide, water and humus.
