Description
Technical field
The method for making that the invention provides a kind of environmentally friendly handheld device electronic curtain repair materials, belongs to repair materialsField.
Background technology
In prior art, handheld device is very universal, comprises smart mobile phone, personal digital assistant, portable game machine, handHold formula computer etc., this kind of equipment has an electronic display screen conventionally, touch-control input. Electronical display (touch) screen of handheld deviceMainly can be divided into condenser type, the large class of resistance-type equivalent according to principle. Although this two classes principle is different, the place that it is identicalBe all that the action of finger presses screen is converted into the signal of telecommunication, and then deliver to CPU end by controller, be transformed into screen by driverCoordinate figure on curtain, and complete the action clicking, and be presented on screen. The method of traditional protection touch-screen is to paste one deck to protectCuticula is generally safety glass film or macromolecule composite protection film. Although pad pasting can play certain protective effect, itsDrawback is: still can not avoid the fragmentation of touch-screen; After having pasted film, can make the reaction of touch-screen slow up. Once soThe breakage of smart mobile phone touch-screen is just difficult to repair later, and often intelligence is changed. This causes a large amount of losses with regard to every annual meeting.
Graphene is a kind of transparent material with carbon element completely, has the characteristic of good conduction. To peel off from graphite materialThe two dimensional crystal that only has one deck atomic thickness out, being formed by carbon atom.
Ionic liquid, as its name suggests, is made up of the salt chemical combination being at room temperature in a liquid state completely zwitterionThing. Different from traditional solid salt, the fuse salt molecule existing with liquid condition has designability, different zwitterion energyEnough be combined into miscellaneous ionic liquid. By selecting different zwitterions, or directly introduce specific functional group and enterRow is modified, and to the character of ionic liquid, adjusts as fusing point, viscosity, hydrophobicity, meets different needs. Ionic liquidBecause the saturated vapor pressure obviously not recording, thereby use ionic liquid more to meet environment than the traditional chemical solvent of useFriendly Green Development theory. Ionic liquid has designability, by adjusting different zwitterions pair, can design kindClass difference, the special ionic liquid that meets different needs comes.
In addition, known to tool applicant and news report, the screen repair materials of prior art is generally special glue, itsMode by gummed is repaired screen crack or breakage, and its weak point is: 1) such adhesive is generally organic adhesive, itsPreparation, use have certain pollution; 2) screen after reparation, performance is limited; 3) repair materials preparation is complicated.
Summary of the invention
The method for making that the object of this invention is to provide a kind of environmentally friendly handheld device electronic curtain repair materials is by stoneAfter China ink alkene, nano-calcium carbonate and certain specific ionic liquid combine, can obtain a kind of transparently, there is piezoelectricity spyProperty and the composite of certain mechanical property, this material, for the reparation of damaged electronic touch screen, can be repaired intelligence fastBreakage and crack that energy mobile phone touch-type glass screen forms due to collision, shock etc., and this material environment close friend, effect is lasting,To user of service's nonhazardous effect.
The concrete technical scheme adopting of the present invention is:
A method for making for environmentally friendly handheld device electronic curtain repair materials, is characterized in that, described repair materialsMethod for making, in turn includes the following steps:
1) first 1-2 weight portion Graphene, 0.5-2 weight portion nano-calcium carbonate are added in 100 parts by weight diluent, stirMix, be uniformly dispersed;
2) add again 0.5-5 weight portion ionic liquid mixture to stir, make repair materials.
Wherein, described ionic liquid mixture is that following two kinds of ionic liquids are according to the mixture of weight ratio 2～6:1;
Wherein, n=1 ?10; This ionic liquid is through well-designed, has transparently, and electrochemical window is wide, and electrical conductivity is largeFeature, is greater than 500m/s, has introduced undersaturated pair of key group especially at its cationic side chain. This pair of key is owing to being to be inIn the right chemical environment of ionic liquid zwitterion, two keys especially easily occur and open self-polymeric reaction, thereby molecular weight increases, and becomesFilm;
This ionic liquid has the feature of above-mentioned ionic liquid equally, special, because its anion contains isocyanate groups,Contact the high molecular reaction of meeting production development carbamate with the compound that contains reactive hydrogen, be used in conjunction with, can increase film forming,Improve reparation speed.
Described Graphene is preferably non-oxidizable Graphene, and described non-oxidizable Graphene is to adopt microwave separation skillArt is permeated gradually intercalator by microwave energy and is made between graphite flake layer, and graphene sheet layer is peeled off gradually without process stoneChina ink alkene oxidation stage. It is prior art products, can on market, obtain or prepare according to prior art.
In the present invention, the average grain diameter of described nano-calcium carbonate is 10-100 nanometer, described diluent be ethanol withAny mixture of water.
In the present invention, the usage of described repair materials is: at temperature is-25～50 DEG C, repair materials of the present invention is coated withCover or be injected at electronic curtain breakage.
Compared with prior art, advantage of the present invention is:
1) the present invention forms a whole to realize intelligence by Graphene, ionic liquid, nano-calcium carbonate and diluentReparation that can mobile phone, compared with common repairing reagent, the present invention has environmental friendliness, transparent, easy to use and be subject toPress and pressure touches and can initiatively produce the characteristic of voltage.
The mechanism that the present invention can initiatively produce voltage is: first Graphene is transparent, exists at nano-calcium carbonateIn situation, there is piezoelectric property, exert pressure and can produce voltage, and described ionic liquid has very wide electrochemical windowAnd electrical conductivity (being greater than 100S/m), the electric current after Graphene pressurized can be conducted out, diluent is adjusted to above-mentioned materialCertain concentration and viscosity, can inject easily cracked Mobile phone screen and be evenly distributed.
