Abstract
The utility model discloses touch leather applicable to capacity touch panels. The touch leather comprises a leather layer, and a polyurethane conducting nano-finishing layer is arranged on the leather layer. Leather treating agents of the touch leather comprise conducting nano-composite polyurethane systems, and the touch leather has comprehensive performance of a common leather coating and a conducting layer. Besides, the leather can have certain conducting performance after tanned leather is treated by finishing agents or the leather treating agents comprising the conducting nano-composite polyurethane systems, and accordingly the touch leather can be applied to touch operation for the capacity touch panels.
Description
Technical field
The utility model relates to a kind of leather.
Background technology
Capacitance technology touch-screen CTP(Capacity Touch Panel) be to utilize the electric current induction of human body to carry out work.Capacitance plate is four layers of compound glass screen; the internal surface of glass screen and interlayer respectively are coated with one deck ITO(nano indium tin metal oxide); outermost layer is the silicon soil glassivation that only has 0.0015mm thick; interlayer ITO coating is made working face; four electrodes are drawn at four angles, and internal layer ITO is for shielding layer to guarantee Working environment.
When the user touches capacitance plate, because people's bulk electric field, user's finger and working face form a coupling capacity, because be connected to high-frequency signal on the working face, so finger is walked a very little electric current, this electric current flows out the electrode from four angles of screen respectively, and the electric current of four electrodes of flowing through in theory and finger are proportional to four jiaos distance, controller calculates by the precision to four current ratios, gets out position.Can reach 99% tolerance range, possess the response speed less than 3ms.
Capacitance plate mainly contains self-capacitance screen and two kinds of mutual capacity screens, take now more common mutual capacity screen as example, inside is comprised of drive electrode and receiving electrode, drive electrode sends the low voltage high-frequency signal and projects receiving electrode and form stable electric current, when human body touches capacitance plate, because human body grounding, finger just forms an equivalent capacity with capacitance plate, and high-frequency signal can flow into ground wire by this equivalent capacity, like this, the quantity of electric charge that receiving end receives reduces, and when pointing the closer to transmitting terminal, electric charge reduces more obvious, and the strength of current that receives according to receiving end is at last determined the point touched.
Therefore capacitance plate is generally by discharging to realize operation, so must come off-line operation with the thing of conduction.As using some with the steel fiber of exotic materials in the fabric gloves, such as silver, copper fiber, can change the absolute inertia of fabric electric current on the ordinary meaning.Thereby the inweaving of special electro-conductive fiber, can make fabric have certain conductivity, thereby satisfy the principle of operation requirement of capacitive touch screen.Equally, when processing leatherware, can utilize some surface treatment agents with conductivity to process leather, so that leather surface has certain conductivity, also can change the insulation attribute of leather, thereby can normally use capacitive touch screen.
Generally speaking, surface treatment agent is the polymer composites that has the mixed with polymers system of conductivity or comprise conductive filler material.And that conducting polymer materials has is lightweight, easily be processed into various complicated shapes, good stability of the dimension and the resistivity characteristics such as adjustable in a big way, therefore has widely purposes in fields such as anti-electrostatic, microwave absorbing, electromagnetic shielding and electrochemistry.Conducting polymer composite material generally is filled conductive filler in polymkeric substance, and the kind of conductive filler material is a lot, and be divided into carbon system and metal commonly used are two large classes.Carbon system comprises carbon black, graphite and charcoal fiber etc.; Metal system mainly contains nano-dispersed particulate or the staple fibre of the metal such as aluminium, copper, nickel, iron or metal oxide.
The utility model content
When the purpose of this utility model is to provide a kind of conduct to touch medium touch capacitive touch screen, can possess the leather that capacitive touch screen touches that is applied to of normal running function.
Technical solution of the present utility model is:
A kind of leather that can be applicable to the capacitive touch screen touch is characterized in that: comprise leather layer, be provided with conductive polyurethane nanometer coatings at leather layer.
The utility model is rational in infrastructure, and leather treatment is that electrical-conductive nanometer composite polyurethane system consists of, and has the over-all properties of conventional leather coating and conductive layer.Tanned leather can make leather have certain conductivity, thereby can be applied to the touch of capacitive touch screen behind the leather treatment or finishing agent processing of electrical-conductive nanometer composite polyurethane system.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
A kind of leather that can be applicable to the capacitive touch screen touch: comprise leather layer 1, be provided with conductive polyurethane nanometer coatings 2 at leather layer.
Making method comprises the following steps:
(1) electrical-conductive nanometer disperses the preparation of body fluid: PVP, the 50ml deionized water of 0.112g are added flask, add the 5mmolL of 25ml under the stirring at room condition
-1The 0.25molL of tannic acid solution and 10ml
-1Ammoniacal liquor, 0.25 molL of dropping 10ml
-1The red-black grain that suspends appears in silver nitrate solution, after continuing to stir, with Precipitation, again through vacuum-drying, obtains the electrical-conductive nanometer silver particle that PVP coats with acetone, gets dissolved in distilled water electrical-conductive nanometer silver particle, prepares the electrical-conductive nanometer dispersion liquid;
(2) the nano combined treatment agent preparation of conductive polyurethane: polyurethane system adopts the aqueous polyurethane leather to process finishing agent PU-745, the electrical-conductive nanometer dispersion liquid that adds preparation, after stirrer stirs, make the nano combined treatment agent of conductive polyurethane with ultrasonic further dispersion;
(3) with the nano combined treatment agent of the above-mentioned conductive polyurethane that makes of leather finish, it is level and smooth to be baked to leather surface under 50 ℃ of conditions, namely obtains can be applicable to the leather that capacitive touch screen touches.
Claims (1)
1. one kind can be applicable to the leather that capacitive touch screen touches, and it is characterized in that: comprise leather layer, be provided with conductive polyurethane nanometer coatings at leather layer.
