Description
Technical field
The present invention relates to a kind of arghan element membrane preparation method.
Background technology
Fructus Ananadis comosi is high in China's annual production, wherein 2013 up to 138.6 ten thousand tons.There is arghan antibacterial, smelly eliminating etc. to protect
Strong performance, which is developed with huge development prospect.The fiber macromolecular alignment of arghan crystal region is neat, have rule
Rule, and the polyhydroxy structure and strong hydrogen bonding effect of cellulosic molecule makes that its degree of crystallinity and the degree of orientation are higher, chemical reactivity is low,
So as to cause its application to be restricted.Therefore, the surcharge of arghan is improved by deep processing so as to obtain multi-field
Extensively to apply, to promoting pineapple industry development with important economic worth and realistic meaning.With cellulose as raw material, system
The macromolecule member material of standby different properties has become the focus of current research, and these cellulose membranes in medical science, biological and food
The fields such as product medicine play an important role.
By cellulose dissolution in NMMO (N. methyl morpholine .N monoxide) solvent, fiber is made by being blow molded extrusion molding
Plain thin film, the film compared with the Lyocell fiber that traditional industry is produced, with dry and wet intensity height, good mechanical property, dimensionally stable
Property it is high, the features such as surface effect is excellent.Zhao Mingxu and Wang Jianqing (2010) prepares cellulose natural complex fresh-keeping film use using NMMO methods
Fresh-keeping in fresh meat, discovery 2.5% inorganic antiseptic of addition is optimal to the inhibition that escherichia coli breed.Ma Bomou etc. (2010)
It is higher than bamboo cellulose film obtained in viscose process using bamboo cellulose film-strength obtained in ionic liquid, can be applicable to different materials
Material field.Cellulose membrane is applied to prepare medical science dialyzer, is as a result shown by configuring blood simulated solution by Li Shuai (2011),
After adding cellulose, the dialyse permeance property of composite membrane, mechanical property, hydrophilicity, antifouling property etc. have clear improvement.
At present, relevant phase inversion prepares the research of natural arghan element film and there is no document report.

Property, drying；
（2）Then the arghan of Jing alkali process is placed in into l, in 5% sulfuric acid solution, fixed solid-liquid ratio 1：35 or 1:55,
In constant temperature oil bath magnetic stirring apparatuss, 100 DEG C of heating 3h, take out sample, are washed to neutrality after process, dry；
（3）A certain amount of ionic liquid is weighed, is mixed with pretreated arghan element and is placed in mulser, control cellulose
Concentration 2%, shearing number of times 2 times, shear rate 16000r/min, that is, obtain cellulose/ion liquid；
（4）25g arghans element/ionic liquid homogeneous phase solution is taken, ultrasonic 5-15min is layered on and scribbles politef not
On rust steel plate, during enough solvents are immersed in after smooth, certain hour is soaked, after cellulose membrane coagulation forming and after precipitation, used
Deionized water is replaced, and after certain hour is dried film；After obtain final product.
The step（1）Oil bath temperature is 95 DEG C, and heat time heating time is 6h.
The step（2）The fixed solid-liquid ratio 1：35.
The ultrasonic time is 10min.
The arghan element film of preparation of the present invention, obtained cellulose membrane have good mechanical property and microcosmic
Structure, permeability ability is good, hydrophilicity is superior, antifouling property is excellent.
