Abstract
The invention discloses a packaging film material with degradability. The packaging film material is prepared from components in parts by weight as follows: 100 parts of corn starch, 10-30 parts of polyethylene oxide, 10-15 parts of polylactic acid, 5-10 parts of polypropylene, 1-5 parts of polyvinyl alcohol, 2-6 parts of chitosan, 0.1-0.6 parts of an antioxidant, 0.1-0.3 parts of a lubricant, 26-34 parts of a plasticizer and 0.1-2 parts of maleic anhydride. The corn starch, polyethylene oxide, polylactic acid, polyvinyl alcohol and chitosan of the packaging film material can be degraded, maleic anhydride is added, the compatibility among the components is improved, the synergistic effect is produced, and the packaging film material has good mechanical properties, higher strength and good tensile, fracture and impact properties; the prepared film can be fully biodegraded and can be widely applied to various film fields.
Description
Technical field
The invention belongs to thin-film material technical field, specifically a kind of packaging membrane material with degradability.
Background technology
Degradable films had not only had the function of conventional plastic and characteristic but also can be after reaching service life, by soil
With the microbial action in water or the effect by the ultraviolet in sunlight, division degraded in natural environment, finally to reduce
Form reenters in ecological environment, goes back to nature.
Starch is widely present in the middle of the plant of nature, aboundresources and cheap, simultaneously biodegradable.Institute
Starch to be added in above-mentioned Biodegradable polyester, the blend of preparation not only can realize complete biodegradable, but also can
To reduce the preparation cost of blend, increase its market competitiveness.
PLA (PLA) is the Starch Conversion being extracted by renewable plant resources such as corn, potatos is glucose, Portugal
Grape sugar becomes lactic acid by fermentation, the aliphatic polyester being polymerized further.The glass transition temperature Tg of PLA is about 55
DEG C, about 180 DEG C of fusing point Tm, have good biocompatibility and high intensity, and can complete biodegradable, after degraded
End-product is water and carbon dioxide, thus, nontoxic, do not result in environmental pollution.Although the high comprehensive performance of PLA, intensity is relatively
Height, but its poor toughness, the elongation at break general 4% about of pure PLA.
Polyvinyl alcohol (abbreviation PVA) outward appearance is white powder, is a kind of quite widely water soluble polymer polymerization of purposes
Thing, between plastics and rubber, its purposes can be divided into fiber and the big purposes of non-fiber two to performance.Because PVA has uniqueness
Strong adherence, epithelium pliability, flatness, oil resistivity, solvent resistance, protecting colloid, gas barrier performance, wearability with
And the specially treated resistance to water having, therefore in addition to making fibrous raw material, also it is largely used to produce coating, adhesive, paper
The products such as product processing agent, emulsifying agent, dispersant, film, range of application is processed, is made throughout weaving, food, medicine, building, timber
The industries such as paper, printing, agricultural, iron and steel, macromolecule chemical industry.
