Description
Technical field
The present invention relates to degradable packing material technical field, in particular it relates to a kind of biomass full degradable packaging material
Preparation method.
Background technology
Packaging group product is mainly Plastic, corrugated paper, honeycomb stationery, paper mould class material at present.Due to Plastic
The discarded object of packaging is not recyclable, non-degradable, and it is a large amount of using serious white pollution is caused, and brings huge environment
Pressure.Corrugated paper, honeycomb stationery, paper mould class material are although degradable, but largely consume China using timber as raw material mostly
The limited forest reserves, and cause water pollution in the fabrication process, manufacturing cost is higher, is not plastics based packaging material
Preferable substitute products.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of preparation method of biomass full degradable packaging material.
The preparation method of a kind of biomass full degradable packaging material disclosed by the invention, it is characterised in that including following step
Suddenly：
The string of 60 mesh is put into aqueous slkali and is beaten brooming；
By starch and water in mass ratio 1：Mixed in 4 addition constant temperature water baths, adjusting the temperature of constant temperature water bath makes its paste
Change, plasticiser is added while stirring；
Starch after being beaten the treated string of brooming, plastifying is put into mixer, after stirring 20min, is put into
Foaming agent and surfactant stirring, form wet feed；
Wet feed is cut and is put into after claiming quality in mould, sets mould temperature as 200 DEG C, lower mould temperature is 205 DEG C, pressure
For 5MPa, pressurize 45s after matched moulds, heat preservation and dryness 30s, takes out packing articles in a mold；
The content of plasticizing agent of packing articles is 12%, the mass ratio of string and starch is 2：5th, foaming agents content is
0.1%th, active agent content 0.3%.
According to the embodiment of the application, surfactant is stearic acid.
According to the embodiment of the application, foaming agent is ammonium hydrogen carbonate.
According to the embodiment of the application, plasticiser be glycerine with ethylene glycol in mass ratio 1：2 composite plastics prepared
Agent.
Compared with prior art, the present invention can be obtained including following technique effect：
The preparation method of the biomass full degradable packaging material of the application is added necessarily using string, starch as major ingredient
Auxiliary material and foaming agent are prepared by special process, with raw material sources are extensive, preparation technology is simple, cost is cheap, Quan Sheng
The advantages that life cycle is environmentally safe, belongs to environmental type packaging material, and agricultural crop straw can be made full use of to provide
Source.
Embodiment
Multiple embodiments of the application will be disclosed below, as clearly stated, details in many practices will with
Illustrate in the lump in lower narration.It should be appreciated, however, that the details in these practices is not applied to limit the application.That is,
In some embodiments of the application, the details in these practices is non-essential.
Prepare raw materials for production, it includes string (rice-straw fibre)：60 mesh；Cornstarch：Average grain diameter about 70nm；Modeling
Agent, surfactant and foaming agent etc., wherein content of plasticizing agent are 12%, the mass ratio of string and starch is 2：5th, send out
Infusion content is 0.1%, active agent content 0.3%.
The string of 60 mesh is put into the aqueous slkali of dilution and carries out being beaten brooming processing.Fiber brooming is in order that planting
The active hydroxy group of fibres more reveals, beneficial to string hydroxy combining；By starch and water in mass ratio 1：4
Mixing, the temperature for then adjusting constant temperature water bath are gelatinized to it, added while stirring the glycerine prepared in proportion and
Ethylene glycol as composite plasticizer, can efficient plasticized starch, improve the encompassing property of starch and fiber, improve the rheological characteristic of slurry
Energy；Starch after being beaten the treated string of brooming, plastifying is put into mixer, after stirring 20min, is put into foaming
Agent, surfactant etc. stir；The wet feed being stirred is cut and is put into after claiming quality in mould, mould temperature in setting
200 DEG C, lower 205 DEG C of mould temperature, and pressure 5MPa, pressurize 45s after matched moulds, heat preservation and dryness 30s, takes out product, i.e., in a mold
Packaging material is made.
More specifically, plasticiser is glycerine and ethylene glycol in mass ratio 1：2 composite plasticizers prepared, activating agent is hard
Resin acid, foaming agent are ammonium hydrogen carbonate, above auxiliary component can be achieved it is degradable, to environment without any harm.
In summary, the preparation method of the biomass full degradable packaging material of the application is using string, starch as major ingredient
Add certain auxiliary material and foaming agent is prepared by special process, with raw material sources are extensive, preparation technology is simple, cost
Cheap, the advantages that Life cycle is environmentally safe, belong to environmental type packaging material, and farming can be made full use of
Thing stalk resource.
The upper only embodiments of the present invention, are not intended to limit the invention.For those skilled in the art
For, the present invention can have various modifications and variations.All any modifications made in spirit and principles of the present invention, it is equal
Replace, improve etc., it all should be included within scope of the presently claimed invention.
