Abstract
The utility model relates to a polycarbonate (PC) transparent conductive composite board. A surface modification layer is coated on the front surface of a PC board; a transparent conductive layer is sputtered on the surface modification layer; one polyethylene (PE) protective film is coated on the transparent conductive layer; a hardened coating is coated on the back surface of the PC board; another PE protective film is coated on the surface of the hardened coating. An optical-grade PC board is adopted to serve as a substrate to replace glass so as to avoid the phenomenon that a product is damaged by an external force in the using process; the surface modification layer is coated on the PC board, so that the adhesion between the substrate and the transparent conductive layer is improved; a nano indium tin metallic oxide is sputtered on the transparent conductive layer in manner of vacuum sputtering, so that the step of pasting a conductive film onto the substrate through optical glue is not needed, and the cost is saved; and the hardened coating is coated on the back surface of the substrate, so that the scratch resistance of the product is improved, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of conduction composite board, relates in particular to a kind of PC electrically conducting transparent composite board.
Background technology
Along with the variation that life is maked rapid progress, touch-screen obtains application more and more widely in fields such as mobile phone, computer, Vehicular display device, digital camera, MP3, automatic ticketing terminating machines.Traditional touch-screen is to use conductive glass as substrate, above superimposed layer of conductive film, middle uniformly dispersing particulate liner prevents that two electrodes can not press close to cause conducting formation induction because of distance up and down, and two electrode edges stamp silver electrode again voltage is provided.Provide pressure that upper/lower electrode is connected with finger or pen during use, predict the screen voltage variation and calculate contacting points position input via controller.Broken easily when using glass to be under pressure as the touch-screen of substrate, influence product quality, so but the substitute of electro-conductive glass more and more becomes the focus of research.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of PC electrically conducting transparent composite board is provided.
The purpose of this utility model is achieved through the following technical solutions:
PC electrically conducting transparent composite board, base material is the PC plate, and characteristics are: the front of described PC plate scribbles surface reforming layer, and sputter has transparency conducting layer on the described surface reforming layer, is covered with the PE diaphragm on the described transparency conducting layer.
Further, above-mentioned PC electrically conducting transparent composite board, wherein, the back of described PC plate scribbles hardening coat, and the hardening coat surface is covered with the PE diaphragm.
Further, above-mentioned PC electrically conducting transparent composite board, wherein, the back roller coat of described PC plate or be coated with hardening coat.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
Adopt the optical grade PC plate of high transmission rate to replace glass, realize the product lightweight as substrate; Utilize the characteristic of PC plate hight anti-impact, avoid in the use because of being subjected to external force to influence broken phenomenon; Conductive layer is directly to form in the mode of substrate surface by vacuum splashing and plating, has saved and has used optical cement to paste the step of conducting film, provides cost savings; At substrate backside coating hardening coat, improve surperficial scratch resistance and chemical resistance, prolonged the service life of product greatly.Be widely used in aspects such as contact panel, electronic game machine, childhood teaching machine, smart mobile phone, panel computer.
