Abstract
The invention relates to the technical field of packaging materials, and discloses a biodegradable packaging material. The packaging material comprises 10-22wt% of octyl succinyl starch ester, 8-20wt% of chitosan, 8-20wt% of xylan, 8-15wt% of mannan, 10-18wt% of polycaprolactone, 1-5wt% of a compatibilizer, 1-5wt% of a coupling agent, 1-5wt% of an antioxidant and 1-3wt% of a plasticizer. The adoption of octyl succinyl starch ester and polycaprolactone as main raw materials increases the water resistance, the tensile performance and the degradability of the packaging material; and the addition of assistants improves the strength, the toughness and the heat resistance of the packaging material and reduces the production cost, and makes the biodegradable packaging material substitute general packaging materials.
Description
Technical field
The present invention relates to field of packaging material, more particularly, to a kind of biodegradable packaging material.
Background technology
Biodegradated polymer materal is by natural polymer (as starch, cellulose, chitin) or agricultural byproducts through microorganism
The macromolecule that fermentation or synthesis have biological degradability is obtained, such as thermoplastic starch plastic, aliphatic polyester, polylactic acid, shallow lake
Powder/polyvinyl alcohol etc. all belongs to this kind of material.What biodegradation material research both at home and abroad was more is divided into following a few class：Starch,
Polycaprolactone (PCL), poly butylene succinate and its copolymer (PBS), polylactic acid (PLA), poly (hydroxyalkanoate)
Ester (PHA), polyvinyl alcohol (PVA) etc..Although the research to biodegradation material both at home and abroad at present and report are a lot,
It is the promotion and application still having many problems to hinder such material.Reason is：1) poor mechanical property of degradation plastic,
Can not meet the use requirement of user, 2) the dim jaundice of degradation material color and luster, transparency is low, and 3) on the high side, cost
Production cost higher than common high molecular materials.
Content of the invention
The technical problem to be solved is to provide a kind of biodegradable packaging material, to overcome prior art can drop
The poor mechanical property of solution plastics, the high defect of color and luster dim jaundice price.
For solving above-mentioned technical problem, the present invention employs the following technical solutions：
A kind of biodegradable packaging material are it is characterised in that include the raw material of following weight portion：Octyl group succinic acid
Starch ester 10 22%, chitose 8 20%, xylan 8 20%, mannan 8 15%, polycaprolactone 10
18%, bulking agent 1 5%, coupling agent 1 5%, antioxidant 1 5%, plasticizer 1 3%.
Preferably, described biodegradable packaging material include the raw material of following weight portion：Octyl group succinic acid starch ester

Preferably, described bulking agent is polypropylene grafted maleic anhydride, the one of which of Polysorbate.
Preferably, described coupling agent is silane coupler, the one of which of rare-earth coupling agent.
The preparation method of the present invention：According to described percentage by weight, above-mentioned raw materials are sufficiently stirred in blender, mixing
Uniformly, it is then placed in heating 8 10 minutes at 120 150 DEG C in moulding press, after embryo processed, be ground into granule.
The present invention adopts octyl group succinic acid starch ester and polycaprolactone as main material, increased the water proofing property of packaging material
Energy, tensile property and degradability；Xylan is main hemicellulose components in plant cell, accounts for plant cell and does
The 35% of weight, is a kind of abundant biomass resource, be in nature in addition to cellulose content polysaccharide the abundantest,
The present invention adopts xylan as raw material, increased the toughness of material, effectively employs the energy, xylan is natural depositing
In degradable, pollution-free；The present invention adds multiple auxiliary agents, improves intensity, toughness and the heat resistance of product, fall
Low production cost, can replace universaling packing material.
