Abstract
The present invention relates to food package film fields, more particularly, to a kind of modified high temperature resistant PE film and preparation method thereof of hybrid inorganic-organic materials.High temperature resistant PE film of the invention is by following quality proportioning at being grouped as: modified 10-15 parts of plant cellulose, 4-6 parts of porous hybrid inorganic-organic materials, 1-3 parts of natural, 1-3 parts of natural antibacterial agent, 70-80 parts of polyethylene matrix, 3-5 parts of acrylic acid.A kind of high temperature resistant PE film and preparation method thereof that hybrid inorganic-organic materials are modified is also disclosed in the present invention, and the food package film of preparation is not only highly-safe, good anti-bacterial effect, can also be resistant to thermophilic digestion.
Description
Technical field
The present invention relates to food package film fields, more particularly, to a kind of modified high temperature resistant of hybrid inorganic-organic materials
PE film and preparation method thereof.
Background technique
Polyethylene (PE) is the powder or particle that nontoxic odorless appearance is creamy white, and is that yield is most in five big synthetic resin
Greatly, the maximum a kind of thermoplastic resin of import volume.Its chemical stability is good, and water imbibition is very low, and resistance to low temperature is good, electrical isolation
Function admirable is widely used in the industries such as agricultural, industry, daily necessities processing industry, is mainly used to produce film, tubing, electricity
Line cable, container, monofilament, high-frequency insulation material etc..Maximum PE purposes is film, and having compared with the film of other classifications makes
With temperature range is wide, mechanical property is good, heat sealing performance is excellent, processability is good, the good characteristics such as easy to process, therefore PE film
Requirement quickly incremental trend is presented year by year.But traditional polyethylene film high temperature resistance is poor, in high-temperature sterilization
It is more easily damaged, significantly limits application of the PE film in food packaging.Therefore, it develops PE film resistant to high temperature and is moulded to PE is expanded
Application of the material in food packaging has great importance.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, provide a kind of hybrid inorganic-organic materials modified resistance to
High temperature PE film and preparation method thereof, the food package film of preparation is not only highly-safe, good anti-bacterial effect, can also be resistant to high temperature steaming
It boils.
In order to achieve the above-mentioned object of the invention, the invention provides the following technical scheme:
A kind of hybrid inorganic-organic materials modified high temperature resistant PE film, it is characterised in that by following quality proportioning at being grouped as:
10-15 parts of modified plant cellulose
4-6 parts of porous hybrid inorganic-organic materials
1-3 parts of natural
1-3 parts of natural antibacterial agent
70-80 parts of polyethylene matrix
3-5 parts of acrylic acid.
Further, the plant cellulose of the modification is hydrophobic nano bamboo fibre.
Further, the porous hybrid inorganic-organic materials are porous polypropylene-nano silica composite wood
Material.
Further, the natural is tea polyphenols, vitamin E presses the compound of 1:0.5-2 mass ratio formation
Antioxidant.
Further, the natural antibacterial agent is that coptis ethanol extract and ginseng ethanol extract press 1:0.5-2 matter
Amount ratio mixes, and wherein content of berberine is not less than 15%, and the content of ginsenoside is not less than 15%.
Further, the high temperature resistant PE membrane preparation method modified the present invention also provides a kind of hybrid inorganic-organic materials,
The following steps are included:
(1) it disperses bamboo fibre powder in 0.1-0.2 mol/L NaOH aqueous solution, it is 3- that density is obtained after ultrasonic 30-40 min
Bamboo fibre dispersion liquid 6%(m/v), by dispersion liquid under the conditions of 80-90 DEG C after boiling 3-5h, in 12000-15000rpm condition
Lower high speed shear 10-20min.After bamboo fibre nanosizing, the silylating reagent of 0.1-0.15 times of cellulose quality is added, in
40-60 DEG C, react 2-4h under the conditions of 500-800rpm, filter, wash, it is dry, obtain hydrophobic nano bamboo fibre；
(2) by C8Ultrasound 30-40 min after the nano silica of modification is mixed with urea liquid, obtaining concentration is 4-5% in (m/
V) silica dispersions, the acrylic acid n-hexane that the 0.1-0.2mol/L of 0.2-0.3 times of volume is added into dispersion liquid are molten
Liquid, after the emulsified 20-40min of 10000-12000rpm high speed shear condition forms stable lotion, at 55-65 DEG C, anaerobic
Under the conditions of react 2-4h after, it is cooling, be filtered, washed, dry to obtain porous polypropylene nano earth silicon material；
(3) natural, natural antibacterial agent is soluble in water, porous polypropylene nano earth silicon material mixing is added
After uniformly, filtering, the porous polypropylene nano earth silicon material of dry carrying active ingredient；
(4) after melting polyethylene matrix, modified plant cellulose, carrying active ingredient are added after being cooled to 110-130 DEG C
Porous polypropylene nano earth silicon material, acrylic acid, be de-gassed 0.5-2 hours, be sufficiently mixed in vacuum degasing machine
Uniformly, film liquid is obtained into, is stood after being cast on a glass at film liquid, film liquid is made to be cooled to room temperature film forming to get organic-nothing
The modified high temperature resistant PE film of machine hybrid material.
Further, silylating reagent as described in step (1) is hexadecyl trimethoxy silane, octadecyl front three
One of oxysilane, hexadecyl.
The prior art is compared, a kind of high temperature resistant PE film and its system that hybrid inorganic-organic materials are modified of the present invention
Preparation Method have the advantages that the present invention nano bamboo fiber is modified using silylating reagent after as the function of PE film
Energy additive, the hydrophobicity of nanofiber enable fiber and PE material well compatible, can not only effectively increase the resistance to of PE film
