Description
Technical field
The present invention relates to a kind of preparation methods of high-intensitive ultra-hydrophobic paper based on LBL self-assembly and thermal induction processing, belong to
In paper post-processing technical field.
Background technique
Packaging industry is mainly using petroleum-based plastics such as polyethylene (PE), polypropylene (PP) as packaging material at present, these
The production of petroleum-based plastics not only consumes a large amount of petroleum resources, but also its a large amount of use will cause serious " white dirt
Dye ", endangers environment.Plant fiber is rich reserves, from a wealth of sources, cheap renewable biomass resources, is had good
Biocompatibility and biodegradability, avirulent feature.It is the paper wrapper of matrix in " green package " using it
Occupy highly important status in industry.Paper wrapper is used to that plastic package material to be replaced to contain liquid or solid matter
Deng should also play the effects of waterproof and dampproof, fresh-keeping other than should have conventional packaging function.Such as flour packaging paper bag
It wants intensity with higher not only to bear the gravity of its content and slight impact, but also wants hydrophobicity with higher
To extend flour storage period.
However, the main component of paper wrapper (Paper or cardboard) is cellulose and hemicellulose, there is extremely strong parent
It is aqueous, moisture is easily absorbed from ambient enviroment, especially under high humidity conditions either with high-moisture materials (such as fresh agriculture
Product) contact when.The intensity of Paper or cardboard depends primarily on the Hydrogenbond between cellulosic molecule, and hydrogen bond is to water electrode that its is quick
Sense, after absorbing moisture, hydrogen bond will be reduced rapidly, so that the mechanical strength of Paper or cardboard reduces, so as to cause storing and circulating
Paper wrapper influences product quality compared with cracky in the process.Therefore, the hydrophobic performance of paper wrapper is improved to raising
Packaging quality is of great significance.
Currently, the existing a large amount of reports of preparation method about super-hydrophobic paper, including grafting modification, magnetron sputtering apply
Cloth, supercritical CO2Rapid expansion, plasma etching method etc..However major part preparation method is often complicated for operation or required
Instrument and equipment complex and expensive.Paper (Huang LH, et al. J. Mater.Sci. 2011,46:2600-2605) is delivered
A kind of straightforward procedure preparing ultra-hydrophobic paper: i.e. super to realize by being filled with the nano-titanium dioxide of silylating reagent into paper pulp
The preparation of hydrophobic paper.However this method makes a large amount of modified nano-titanium dioxide be covered on fiber surface, causes into fine when paper
Hydrogenbond is greatly decreased between dimension and fiber, so that paper strength be caused inevitably to damage.When silylating reagent nanometer
When the titanium dioxide amount of being filled with is 13%, the water contact angle of handmade paper is up to 157.7 °, but its tensile strength has lost compared with control sample
About 38%.It can be seen that the ultra-hydrophobic paper intensity difference prepared by this method, limits its application as packaging material in practice.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of based on LBL self-assembly and thermal induction
The preparation method of the high-intensitive ultra-hydrophobic paper of processing.The method of the present invention operation and equipment are simple and easy to get, overcome traditional super thin
Water paper making process is cumbersome, and required the device is complicated expensive defect is suitble to industrialized production.The present invention passes through following technical side
Case is realized.
A kind of preparation method of the high-intensitive ultra-hydrophobic paper based on LBL self-assembly and thermal induction processing, specific steps are such as

20min, wherein nano-titanium dioxide-ethanol solution concentration of hexadecyl trimethoxy silane graft modification is 2 ~ 4g/L；
(3) it is repeated in step (1) and (2) 20 ~ 30 times, finally processed is placed in above-mentioned under the conditions of 140 ~ 160 DEG C
20 ~ 30min is handled, high-intensitive ultra-hydrophobic paper is obtained.
Chitosan solution pH value in the step (1) is 5 ~ 5.7.
The preparation method of the nano-titanium dioxide of hexadecyl trimethoxy silane graft modification in the step (2): first
Be first that 95:5 is uniformly mixed to obtain organic solvent according to volume ratio by dehydrated alcohol and deionized water, then according to organic solvent and
Hexadecyl trimethoxy silane liquid-solid ratio is that hexadecyl trimethoxy silane is added in 100:0.5 ~ 0.8mL/g, in room temperature item
30 ~ 40min is stirred under part, is then 0.5 ~ 0.8 according still further to hexadecyl trimethoxy silane and nano-titanium dioxide mass ratio:
4 ~ 5 are added nano-titanium dioxides, under the conditions of 60 ~ 70 DEG C are stirred to react 60 ~ 120min, after reaction, are centrifuged, isolate
Precipitating is washed with dehydrated alcohol, and the nano-titanium dioxide of hexadecyl trimethoxy silane graft modification is obtained after vacuum drying.
The nano-titanium dioxide of the above-mentioned hexadecyl trimethoxy silane graft modification being prepared be partial size 50 ~
100nm's is powdered.
The beneficial effects of the present invention are:
(1) ultra-hydrophobic paper of the method for the present invention preparation, nanoscale silylating reagent is realized using layer-by-layer
Titanium dioxide and chitosan multilayer film have constructed biggish asperity structure in paper surface in the load of paper surface, are paper
The realization for opening surface super hydrophobic performance constructs well suitable structure basis；Then by subsequent heat treatment, so that modified
Hydrophobic Long carbon chain on titanium dioxide tends to the outside of multilayer film, the surface energy of paper is reduced, to realize paper surface
Superior ultra-hydrophobicity.The method of the present invention operation and equipment are simple and easy to get, overcome traditional super-hydrophobic paper preparation process
Cumbersome, required the device is complicated expensive defect is suitble to industrialized production.
(2) paper prepared by the present invention not only has super-hydrophobic characteristic, but also its strength character has also obtained greatly
Improvement.After tested, paper surface first adsorbs 25 double-deck chitosan/silanization nano-titanium dioxide multilayer films, then through 150 DEG C
