Description
Technical field
The present invention relates to arghan packaging film technical field, particularly relate to a kind of new welan gum blending and modifying Pullulan
Polysaccharide graft pina fibre packaging film and preparation method thereof.
Background technology
With cellulose as raw material, the different macromolecule member material of processability is at necks such as medical science, biology and food medicine
Territory plays an important role, and has become as the focus of current research.China often produces substantial amounts of Fructus Ananadis comosi per year, and arghan has
The health-care effecies such as antibacterial, smelly eliminating, utilize arghan to prepare macromolecule member material and have huge development prospect.Pineapple leaves is fine
The fiber macromolecular alignment of dimension crystallization song is neat, regular, and the polyhydroxy structure of fiber molecule and strong hydrogen bonding effect make it clean
Cleanliness and the degree of orientation are higher, and chemical reactivity is low, thus cause its application to be restricted." the agriculture in south such as Wei Xiaoyi, Yang Qin
Journal ", 2016,47(1): 101-106 " arghan element film preparation process optimization " utilizes emulsifying cut mode to make pineapple leaves
Cellulose dissolution improves the chemical reactivity of arghan in ionic liquid, it is achieved the preparation of cellulose membrane, specifically does
Method is: be ground into cotton shape with Universalpulverizer after first being dried by arghan element, and alkali processes and acid treatment realizes it respectively
Purification process, is then being placed in together with ionic liquid in mulser, is carrying out shear treatment, acquisition prepare the cellulose of film from
Sub-liquid homogeneous phase solution, is layered on homogeneous phase solution on the carrier scribbling politef afterwards, through casting solution (glycerol, second
Alcohol) etc. soak drying and forming-film；This process technique improves the chemical reaction activity of arghan element, improves the equal of coating solution
Phase, but operate and employ substantial amounts of acidizer and alkali inorganic agent, adds somewhat to pollute, add Fructus Ananadis comosi
Leaf fibre element film preparation cost, the cellulose membrane function singleness simultaneously prepared.Nano-cellulose have high-crystallinity, high intensity,
The excellent properties such as high-specific surface area, environmental friendliness and low cost, also exist substantial amounts of-OH in its molecular structure, with other skies
So macromole is easily formed intermolecular and intramolecular hydrogen bond when being blended, and when being used for making membrane material, can make the formation of intermingling material
Membrane structure more stable.Micro-nano bubble refers to that diameter is between micron bubble (bubble of a diameter of 10-50um in water body)
And the bubble between nano bubble (a diameter of bubble less than 200nm in water body), have big specific surface area, can be at water
In body, the time of staying is long, and micro-nano bubble is when shrinking, it is possible to produce substantial amounts of hydroxyl radical free radical, these substantial amounts of hydroxyls
Free radical can attract the hydrogen bond in arghan element to a certain extent, plays equivalent acidifying alkalization and destroys the effect that hydrogen bond is identical
Really, the nanorize promoting arghan is improved its chemical reaction activity and there is certain facilitation.Pulullan polysaccharide is
The polymer substance of colorless and odorless odorless, has edibility and biodegradability, has good film property, the thin film tool made
There are good gas barrier property and water preventing ability, but containing substantial amounts of hydrophilic radical on pulullan polysaccharide strand, can be with other
Fibrous material combines the fibrous membrane prepared, but these fibrous membranes chance water is instant, limits its application on some packaging films；
The fibrous membrane that arghan based on modified pulullan polysaccharide and high chemical reactivity combines is to improving pineapple leaves
Comprehensive utilization and abundant packaging film kind are significant.
