Description
Technical field
The invention belongs to green functional material and its preparing technical field, it is related to a kind of biomass resource and prepares flexible and transparent
The method of material.
Background technology
In recent years due to portability outstanding, shape variability and human body applicability, flexible electronic technology has become the whole world
The new focus of electronic industry circle and academia's concern.Currently used electronic device is mainly built in silicon chip, glass and plastics
On film, these base materials are difficult to degrade under natural environmental condition, and huge load is brought to environment for the survival of mankind.Together
When, it is used to prepare raw material-oil of these base materials, cost is higher and higher, and reserves are also reduced increasingly.Therefore, to prevent ring
The wasting of resources is polluted and is reduced in border, is developed and used inexpensive, recyclable, degradable green bio matter resource and is prepared flexible and transparent
Electronic substrate, will certainly be to realizing that the technological change of the strategy of sustainable development and new material exerts far reaching influence.
Cellulose is environmentally protective with its, renewable, can drop as a large amount of existing natural polymer child resource in nature
The advantages that solving, derive from a wealth of sources, is easily modified is manufactured paper with pulp by it into paper base material as research hotspot in recent years, inexpensive, light,
It is flexible, bent and there is certain heat resistance, but because of cellulose (refractive index is about 1.5) and pore interior air (refractive index
About 1.0) larger refractive index difference causes the opacity of material higher.The cellophane paper of Traditional Industrialization production is mainly adopted
It is manufactured paper with pulp with the fiber of high beating degree, the scale that is big, of high cost, cannot achieve high quantitative transparency paper of this method energy consumption
Production.
In order to solve these problems, domestic and foreign scholars have carried out a large amount of research work.Patent US 2646369 is disclosed
A kind of " preparation process of cellophane paper " technology, the technology are sealed using gasoline distillate, paraffin and carbon tetrachloride etc. at (dipping)
Body paper is managed, obtains the paper with certain transparency, but because being impregnated by organic volatile, material still has larger thorn in a couple of days
Swash property smell.Patent CN 106012667A disclose " a kind of holocellulos cellophane paper and preparation method thereof ", and the technology is with tradition
The paper or plant fiber that paper technology obtains be network skeleton, using the homogeneous cellulose solution of certain solubility be filler with
Dissolving medium, even spread to paper or plant fibre surface；Flatness is improved by later stage finishing process, is formed integrated
Cellulose composite construction is prepared for a kind of inexpensive holocellulos cellophane paper.Patent CN 106917311A disclose " a kind of saturating
Wood materials are processed into sawdust or wood powder by the preparation method of bright paper ", the technology first, then sodium hypochlorite are used to remove wherein
Lignin, then wash with water remaining sodium hypochlorite, finally pass through press processing and remove remaining moisture, obtain cellophane paper.
Patent CN 105568747A disclose " a method of preparing nano-cellulose paper using stalk ", and the technology is first with secondary
Sodium chlorate removes the lignin in stalk, then prepares nano-cellulose with 1,3-Dihydroxyacetone oxidation system, then through filter membrane
It filters, squeeze and is dried, obtain nano-cellulose cellophane paper.Patent CN 107119496A disclose " a kind of maceration extract and
It quickly prepares the application of the transparency paper of the method for transparency paper and preparation ", the technology first by body paper be placed in clarifier, thoroughly
It is impregnated in the maceration extract of the compoundings such as bright auxiliary agent, surfactant, water repellent agent, lubricant and crosslinking agent, then by the paper after dipping
Zhang Jinhang drying, press polish processing, obtain transparency paper.
However, above-mentioned various methodologies or the more auxiliary agent of use (such as clarifier, water repellent agent, lubricant and crosslinking agent) carry out
Dipping or preparation process are complex and mostly use sodium hypochlorite bleaching and be also easy to produce the noxious materials such as bioxin, or need elder generation
Solution is made in cellulose, cost of manufacture is higher, solvent is difficult to recycle, and the cellophane paper prepared exists again that transparency is low, toughness
The defects of difference, intensity can not ensure.
Invention content
For being used in current cellophane paper preparation process, auxiliary agent is excessive, preparation process is complicated, of high cost；The cellophane paper of acquisition
The problem that transparency is low, poor toughness, intensity are low, the present invention provide that a kind of intensity is high, toughness is big, transparency is high, can natural degradation
The preparation method of cellophane paper and products thereof.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of preparation method of flexible biological matter base transparent material, includes the following steps：
(1) finished pulp discongested, be beaten, obtain paper pulp；
(2) paper pulp in step (1) is copied and is taken as paper web；
(3) paper web for obtaining step (2) is coated with coating solution；
(4) wet web that step (3) obtains is transferred on hot press and carries out press polish, is dried, obtained biomass-based flexible saturating
Bright material.
In step (1), the finished pulp is selected from bleached softwood wooden chemistry slurry, bleaching hardwood chemical pulp, bleached softwood wood
