Abstract
The invention discloses a kind of preparation method of degradable packaging bag, comprise 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 product packaging.
Description
Technical field
The present invention relates to packaging bag, more particularly to a kind of preparation method 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 preparation method of degradable packaging bag, and solving existing packaging bag can not
The problem of degraded.
Technical scheme：A kind of preparation method of biodegradable bag of the present invention, is comprised the steps of：(1) raw material
Prepare：After each component is stirred together for uniformly, ground repeatedly under normal temperature on three-roll grinder, into slurry viscosity 60PaS or so
It is standby；(2) calendering technology：Above-mentioned composition is overlayed into plastic layer on four-roller machine；(3) print：Carried out on intaglio press,
The surface layer film printed is attached on leather next process is counter；(4) veneer tunic：By printing dried semi-finished product compound
Pad pasting on machine, obtains finished product.
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.
The packaging bag mainly includes following components：By weight, 9-10 parts 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.
Beneficial effect：Packaging bag prepared by the present invention is degradable, and preparation process is simple, environmental protection, can large-scale industrialization
Production.
Embodiment
First, sample preparation
Embodiment 1：By weight, 9 parts of polyurethane, 10 parts of starch, 1 part of crosslinking agent di-tert-butyl peroxide, 5 parts help
