Detailed description of the invention
The method that employing Exocarpium Juglandis Immaturus provided by the present invention is prepared living beings plastics below is made
Elaborate.
<embodiment one>
In the present embodiment, the method using Exocarpium Juglandis Immaturus to prepare living beings plastics includes following step
Rapid:
Step one, the pretreatment of Exocarpium Juglandis Immaturus.By Exocarpium Juglandis Immaturus natural air drying, then will air-dry after
Exocarpium Juglandis Immaturus cut into, by pulverizer, the blocky-shaped particle that particle diameter is 0.1～0.5cm.Then to
These blocky-shaped particles add the concentration ammoniacal liquor less than 10%, is not damaging the organic of Exocarpium Juglandis Immaturus
Soften Exocarpium Juglandis Immaturus in the case of thing and degrade lignin therein, contributes to subsequent step
Process.
Step 2, organic purification.It is the most unfavorable still to contain in pretreated Exocarpium Juglandis Immaturus
In the impurity of generation living beings plastics, so the carbohydrate in Exocarpium Juglandis Immaturus and protein etc. are had
Machine thing purifies, and removes objectionable impurities therein.In pretreated Exocarpium Juglandis Immaturus particle
Add the Na of 0.5%2CO3Use plant membrane to organic matter and Na after solution, fully reaction2CO3
The reaction solution of solution carries out dialysis process, obtains the organic matter purified.In purification process not
The chemical reagent of strong acid or highly basic can be used, in order to avoid organic components is damaged.
Step 3, organic degenerative treatments.Salt is added in the organic matter that step 2 extracts
Acid, is heated to 90～110 DEG C, is incubated 30min, is stirred solution simultaneously, stirring speed
Rate is 75r/min.This process can make organic chemical attribute change, original
Structure is unfolded into new membrane structure.
Step 4, the preparation of living beings plastics.Organic matter water after sex change that what step 3 obtained is
Solution, dries it at 240 DEG C, makes moisture evaporate, i.e. can get living beings plastics.Dry
Dry temperature can affect the quality of the living beings plastics obtained, too high or too low for temperature, the life prepared
The ductility of material plastics is the most poor.
<embodiment two>
In the present embodiment, the method using Exocarpium Juglandis Immaturus to prepare living beings plastics includes following step
Rapid:
Step one, the pretreatment of Exocarpium Juglandis Immaturus.Exocarpium Juglandis Immaturus is put into gas explosion device, at 210 DEG C
Under carry out Steam explosion treatment, the process time is 10～20min.Thus destroy in Exocarpium Juglandis Immaturus
Plant structure, a large amount of lignin degradings.
Then use the step identical with the step 2 of embodiment one～step 4 to pretreated
Exocarpium Juglandis Immaturus carries out organic purification, degenerative treatments and drying, obtains living beings plastics.
It addition, the living beings plastics that Exocarpium Juglandis Immaturus is prepared as are rich in gal4 amino acid and high polymerization
Sugar, beneficially bacterial reproduction, so living beings plastics are it may happen that corruption of going mouldy, affect it
Use as plastics.Especially for the plastics of packaged food, need to meet higher safety
Hygienic requirements.Therefore, the preparation process of living beings plastics is wanted test organisms matter plastics whether
There is corruption of going mouldy, if there is, it is necessary to take measures to eliminate the impact of corruption of going mouldy in time.
The effect of embodiment and effect
The Exocarpium Juglandis Immaturus that uses according to embodiment one and embodiment two prepares the side of living beings plastics
Method, because carrying out the pretreatment of physics, chemistry or HTHP, by green grass or young crops walnut to Exocarpium Juglandis Immaturus
Lignin degradation in skin, destroys its plant structure, then uses Na2CO3Solution and dialysis
Organic matter in Exocarpium Juglandis Immaturus is extracted by method, after addition hydrochloric acid solution at high temperature sex change
Reason, then the moisture drying of organic aqueous solution can be obtained living beings plastics, therefore this is prepared
Method can carry out regeneration to the organic matter in Exocarpium Juglandis Immaturus, reduces agricultural waste and resource
Waste；And living beings plastics are easily degraded, replace chemical industry synthetic plastic, it is possible to effectively subtract
Few environmental pollution.
Certainly, the method that employing Exocarpium Juglandis Immaturus provided by the present invention prepares living beings plastics, and
It is not only limited to the content described in above example.These are only the base under present inventive concept
This explanation, and according to any equivalent transformation that technical scheme is made, all should be belonged to this
The protection domain of invention.
It addition, in embodiment one, use the concentration ammoniacal liquor less than 10% that Exocarpium Juglandis Immaturus is carried out
Pretreatment, destroys its plant structure, lignin degrading, it is also possible to using concentration is 0.1～1
Exocarpium Juglandis Immaturus is pre-processed by the NaOH solution of mol/L, it is also possible to reach identical effect.
