Description
Technical field
The invention belongs to field of packaging material, and in particular to a kind of using dogstail as the preparation side of the wrapping paper of raw material
Method.
Background technology
With the continuous development of packaging material industry and the raising of people's environmental consciousness, gradually increase to degradable
The research of packaging material, but the problem of due to material and technology, the research of degradable package material is also relatively fewer, existing skill
Usually using timber papermaking in art, and dogstail is using less, to find out its cause, being because straw pulp is compared with wood pulp, fiber is averagely long
Spend that short, fibre diameter is small, it appears stiff, fibrocyte wall thickness, cell are small, and heteroproteose cell content is more, therefore using papermaking straw pulp into
During row mashing, beating degree rises fast but is not easily accomplished external fibrillating, and secondly content of lignin is relatively low, and straw pulp fiber is secondary
Wall outer wall is thicker, causes the imbibition of fiber and fibrillating all extremely difficult, the intensity of paper is easily influenced with papermaking straw pulp, can not
Meet requirement, therefore, it is necessary to how to improve the strength study using straw pulp as the wrapping paper of raw material.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of preparation side using dogstail as the wrapping paper of raw material is provided
Method.
The present invention is achieved by the following technical solutions：It is a kind of using dogstail as the preparation method of the wrapping paper of raw material, bag
Include following steps：
（1）Particle is broken into after dogstail material is cleaned, when then drying 2-4 is small under 75-85 DEG C of vacuum condition, is ground into
Powder crosses 80-100 mesh sieves, obtains dogstail powder；
（2）By dogstail powder through boiling, shove, wash, discongest after obtain straw pulp, the beating consistency of the straw pulp is 3.0-
4.0%；
（3）By weight, take 6-10 parts of graphene oxide, be dissolved in be equivalent to after the water of 4-6 times of its weight be ultrasonically treated 4 it is small when,
Then 0.2-0.8 parts of hexamethylene diisocyanates are added in, after magnetic stirring for 10 minutes is ultrasonically treated 20 minutes, obtains again
Graphene oxide solution adds in 4-6 parts of carbon nanotubes and 25-35 parts of polystyrene, is controlled under conditions of temperature is 85-125 DEG C
When system reaction 2-4 is small, reaction material is obtained；
（4）By weight, 40 parts of straw pulp is taken to be mixed with 12-16 parts of reaction materials, is crumpled under the pressure of 0.42-0.48kg/cm2
When 1-2 is small, adds in distilled water and diluted three times, obtain slurries；
（5）The starch, 2-4% sucrose fatty esters, the alginic acid of 1.2-1.6% for being equivalent to its weight 6-10% are added in slurries
Sodium, 0.2-0.8% nano-calcium carbonates, after mixing secondary mashing, beating degree are 32-36 ° of SR；
（6）By secondary mashing liquid using mould molding, wrapping paper is obtained.
As further improvement of these options, the thickness of the wrapping paper is that starch described in 0.06-0.12mm is sun
Dogstail described in ionic starch is wheat, rice, cotton or corn lamp stalk.
As further improvement of these options, the step（2）In reaction temperature be 105-115 DEG C；The magnetic
The mixing speed of power stirring is 1200-1500 revs/min, and working method is to continuously stir.
The present invention has the following advantages compared with prior art：Graphene oxide, carbon nanotubes and polyphenyl are utilized in the present invention
Ethylene prepares reaction material under the high temperature conditions, and gained reaction material mixes rubbing with straw pulp, can come into full contact with raw material, reduces two
The secondary mashing cut-out excessive to fiber, effectively avoids the influence to fracture length, tearability, improves paper strength, and reduction manufactured
Pollution in journey, the paper produced is thin and toughness, by adding in sodium alginate and nano-calcium carbonate, can be used as between fiber
Node, enhance the tensile strength of paper, and then improve paper strength, while the bacteriostasis of paper can also be improved, paper is saturating
Gas is good, itself is non-toxic, applied widely.
