Abstract
The invention discloses a kind of degradable packaging bag, mainly consist of the following composition：9 10 parts of polyurethane, 10 20 parts of starch, 18 parts of crosslinking agents, 5 10 parts of cosolvents and 20 25 parts of celluloses.A kind of degradable packaging bag preparation method, is comprised the steps of：Raw material preparation, calendering technology, printing and veneer tunic, obtain finished product.Packaging bag prepared by the present invention is degradable, and preparation process is simple, environmental protection, available for packaging for foodstuff.
Description
Technical field
The present invention relates to packaging bag, more particularly to a kind of degradable packaging bag.
Background technology
Packaging bag refers to the sack for packing various articles for use, makes goods convenience in transport in the process of circulation is produced, easily
Storage.It is widely used in daily life and industrial production.Real figure shows there is the polybag after 80% use, finally with one
As rubbish be equally transported to the processing of rubbish heap field area, only 7 percent plastics are recovered recycling.
The content of the invention
Goal of the invention：The present invention provides a kind of degradable packaging bag, solves the problems, such as that existing packaging bag can not degrade.
Technical scheme：A kind of biodegradable bag of the present invention, mainly comprising following components：By weight, 9-10
Part polyurethane, 10-20 parts starch, 1-8 parts crosslinking agent, 5-10 parts cosolvent and 20-25 part celluloses.
The crosslinking agent is selected from di-tert-butyl peroxide or di-isopropylbenzene hydroperoxide.
The cosolvent is selected from polysorbate60, span 80 or this disk 60.
Above-mentioned composition includes following components, by weight, 9-10 parts polyurethane, 10-15 parts starch, the crosslinking of 3-5 parts
Agent, 5-8 parts cosolvent and 23-25 part celluloses.
Further, above-mentioned composition includes following components：By weight, 10 parts of polyurethane, 13 parts of starch, 4 parts of friendships
Join agent, 6 parts of cosolvents and 24 parts of celluloses.
Above-mentioned degradable packaging bag preparation method, is comprised the steps of：(1) raw material prepare：Each component is stirred together for
After uniformly, ground repeatedly under normal temperature on three-roll grinder, it is standby into slurry viscosity 60PaS or so；(2) calendering technology：Will
Above-mentioned composition overlays plastic layer on four-roller machine；(3) print：Carried out on intaglio press, the surface layer film printed is under
One procedure is counter to be attached on leather；(4) veneer tunic：By printing dried semi-finished product pad pasting on compounding machine, finished product is obtained.
The plastic layer is in 1-1.2mm.
The four-roller linear velocity 5-10m/min.
It is 90-100 DEG C that the compounding machine combined temp, which is controlled in pre- hot-rolling, and heating roller is 150-180 DEG C.
Beneficial effect：Packaging bag prepared by the present invention is degradable, and preparation process is simple, environmental protection, can large-scale industrialization
Production.

Embodiment 4：10 parts of polyurethane, 15 parts of starch, 5 parts of crosslinking agent di-isopropylbenzene hydroperoxides, 8 parts of cosolvent span 80s
With 25 parts of celluloses.
Embodiment 5：10 parts of polyurethane, 13 parts of starch, 4 parts of crosslinking agent di-tert-butyl peroxides, 6 parts of cosolvent polysorbate60s
With 24 parts of celluloses.
2nd, detection method
1st, degraded solutions：1.5mol/L hydrochloric acid is molten
2nd, biodegrading process refers to CIPAC MT 176《The rate of dissolution of water-soluble bag》
3rd, testing result
Sample prepared by embodiment 1-5, point three groups of parallel tests, measurement result is shown in Table 1, it can be seen from the result of table 1
Packaging bag prepared by the present invention can degrade under strongly acidic conditions, and packaging bag can focus on, and will not cause environmental pollution.
The sample degradation speed of table 1
