Description
Technical field
The present invention provides a kind of environmentally friendly smart phone self-repair material and usages, belong to repair materials field.
Background technique
Smart phone has become instantly the most universal " household electrical appliance ", almost manpower one.Authoritative department, it is expected that
China's smart phone yield will break through 5.5 hundred million within 2015.Now, smart phone can substitute most computers or
The work of laptop, such as surf the web, friend-making chat, receiving and dispatching mail, simply write material.Smart phone is generally all
Glazing touch screen while bringing convenient to us, while also bringing very frangible drawback.I.e. present intelligent hand
Machine is far from functional mobile phone " sturdy " once.Smart phone touch screen can be mainly divided into condenser type, resistance-type according to principle
Etc. two major classes.Although these two types of principles are different, its identical place is all to convert electricity for the movement of finger pressing screen
Signal, and then the end CPU is sent to by controller, the coordinate value on screen is transformed by driver, and the movement clicked is completed, and
It presents on the screen.The method of traditional protection touch screen is patch layer protecting film, 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
It is broken；Having pasted film can make the reaction of touch screen slow up later.So being difficult to repair after once smart phone touch screen is damaged
It is multiple, 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
An object of the present invention is to provide a kind of environmentally friendly smart phone self-repair material, is by graphene, receives
Rice calcium carbonate and after certain specific ionic liquid is combined, available one kind is transparent, with piezoelectric property and
The composite material of certain mechanical properties, reparation of the material for damaged electronic touch screen, can quickly repair smart phone
Glass touch screen is formed by damaged and crack due to colliding, hitting etc., and the material environment is friendly, persistent, to intelligence
Mobile phone user of service's nonhazardous effect.
It is a further object to provide the preparation method of the material and usages.
The technical solution that the present invention specifically uses are as follows:
A kind of environmentally friendly smart phone self-repair material, characterized in that the self-repair material is by following parts by weight
Raw material mix:
Wherein, the chemical formula of the ionic liquid is
Wherein, n=1-10, preferred n=1-5.
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.
The usage of environmentally friendly smart phone self-repair material, which comprises the steps of:
1) first graphene, nanometer calcium carbonate are added in diluent, stir, is uniformly dispersed；
2) ionic liquid stirring is added, self-repair material is made；
3) in the case where temperature is -25~50 DEG C, self-repair material is coated or is injected at smart phone screen breakage i.e.
It can.
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.
