Description
Technical field
The present invention provides a kind of preparation methods of environmentally friendly handheld device electronic curtain repair materials, belong to repair materials
Field.
Background technique
In the prior art, handheld device is very universal, including smart phone, personal digital assistant, portable game machine, hand
Formula computer etc. is held, such equipment usually has an electronic display screen, touch-control input.The electronical display (touch) of handheld device shields
It can be mainly divided into condenser type, resistance-type equivalent major class according to principle.Although these two types of principles are different, its identical place
All it is to convert electric signal for the movement of finger pressing screen, and then the end CPU is sent to by controller, screen is transformed by driver
Coordinate value on curtain, and the movement clicked is completed, and present on the screen.The method of traditional protection touch screen is one layer of guarantor of patch
Cuticula, usually tempered glass film or macromolecule composite protection film.Although pad pasting can play a certain protective role, its
Drawback is: not still being avoided that the broken of touch screen；Having pasted film can make the reaction of touch screen slow up later.So once
It is difficult to repair after smart phone touch screen is damaged, often intelligence replacement.This just will cause a large amount of loss every year.
Graphene is a kind of fully transparent carbon material, the characteristic with good conduction.It is to be removed from graphite material
Out, the two dimensional crystal for the only one layer of atomic thickness being made of carbon atom.
Ionic liquid is exactly as its name suggests the salt chemical combination that is in a liquid state at room temperature completely as composed by zwitterion
Object.It is different from traditional solid salt, there is designability, different zwitterion energy with melting molecules of salt existing for liquid condition
Enough it is combined into miscellaneous ionic liquid.By selecting different zwitterion, or be introduced directly into specific functional group into
Row modification, is adjusted the property of ionic liquid, such as fusing point, viscosity, hydrophobicity, to meet different needs.Ionic liquid
Because the saturated vapor pressure obviously not measured, thus using ionic liquid than using traditional chemical solvent to be more in line with environment
Friendly Green Development theory.There is ionic liquid designability can design kind by adjusting different zwitterions pair
Class is different, and the special ionic liquid for meeting different needs comes.
In addition, tool applicant is known and news report, the screen repair materials of the prior art are generally special glue,
Screen crack or breakage are repaired by way of glued, the disadvantages are as follows: 1) such adhesive is generally Organic adhesive,
Preparation, using there is certain pollution；2) screen after repairing, limited performance；3) repair materials preparation is complicated.
Summary of the invention
The object of the present invention is to provide a kind of preparation methods of environmentally friendly handheld device electronic curtain repair materials, are by stone
After black alkene, nanometer calcium carbonate and certain specific ionic liquid are combined, available one kind is transparent, has piezoelectricity special
Property and certain mechanical properties composite material, reparation of the material for damaged electronic touch screen can quickly repair intelligence
Can mobile phone glass touch screen due to colliding, hitting etc. be formed by damaged and crack, and the material environment is friendly, persistent,
User of service's nonhazardous is acted on.
The technical solution that the present invention specifically uses are as follows:
A kind of preparation method of environmentally friendly handheld device electronic curtain repair materials, characterized in that the repair materials
Preparation method in turn includes the following steps:
1) first 1-2 parts by weight of graphite alkene, 0.5-2 parts by weight nanometer calcium carbonate are added in 100 parts by weight diluent, are stirred
It mixes, be uniformly dispersed；
2) stirring of 0.5-5 parts by weight ionic liquid mixture is added, repair materials are made.
Wherein, the ionic liquid mixture is mixture of the following two kinds ionic liquid according to 2~6:1 of weight ratio；
Wherein, n=1-10；The ionic liquid has transparent, an electrochemical window mouth width by well-designed, and conductivity is big
Feature is greater than 500m/s, particularly introduces unsaturated double bond group in the side chain of its cation.The double bond is due to being to be in
In the chemical environment of ionic liquid zwitterion pair, it is particularly easy to that double bond opening self-polymeric reaction occurs, so that molecular weight increases, at
Film；
The ionic liquid is same
Sample has the characteristics that above-mentioned ionic liquid, particularly, since its anion contains isocyanate groups, with the chemical combination containing reactive hydrogen
The object contact meeting high molecular reaction of production development carbamate, is used cooperatively, can increase film forming, improve and repair speed.
The graphene is preferably non-oxidizable graphene, and the non-oxidizable graphene is using microwave separation skill
Art is gradually permeated intercalator by microwave energy between graphite flake layer and is made, removes graphene sheet layer gradually and need not move through stone
Black alkene oxidation stage.It is prior art products, can be obtained on the market or according to prior art preparation.
In the present invention, the average grain diameter of the nanometer calcium carbonate is 10-100 nanometer, the diluent be ethyl alcohol and
Any mixture of water.
In the present invention, the usage of the repair materials is: in the case where temperature is -25~50 DEG C, repair materials of the present invention being applied
Cover or be injected at electronic curtain breakage.
Compared with prior art, the invention has the advantages that
1) present invention is graphene, ionic liquid, nanometer calcium carbonate and diluent to form a whole to realize intelligence
Can mobile phone reparation, compared with the common repairing reagent, the present invention have it is environmental-friendly, transparent, convenient to use and by
Pressing and pressure touch can actively generate the characteristic of voltage.
The mechanism that the present invention can actively generate voltage is: graphene is transparent first, existing for nanometer calcium carbonate
In the case of there is piezoelectric property, i.e. application pressure can generate voltage, and the ionic liquid has very wide electrochemical window
With conductivity (being greater than 100S/m), the electric current after graphene can be pressurized, which transfers out, to be come, and diluent arrives above-mentioned material adjusting
Certain concentration and viscosity can easily inject the Mobile phone screen of fragmentation and be evenly distributed.
2) composite material environment of the invention is friendly, and persistent is easy to use, non-toxic to humans.
