Broadband transparent shielding material composite structure and composite glass and OCA back glue structure

Abstract

Broadband transparent shielding material composite structure and composite glass and OCA back glue structure. It mainly solves the problem that the broadband electromagnetic shielding can not achievehigh protection efficiency. Characterized by comprising a first base material layer, a second base material layer and a third base material layer, wherein a metal shielding grid layer is arranged between the first base material layer and the second base material layer, and a transparent conductive layer is arranged between the second base material layer and the third base material layer. A light-transmitting and shield composite structure with wide frequency band and a composite glass and OCA back glue structure are provided, Making full use of the complementary effect of the low resistance characteristic of metal shielding mesh and the high resistance characteristic of ITO material, At that same time, the PET matrix material is composite into a multi-layer integrated structure, On the basis of ensuring light transmittance and eliminating Moire fringe, good electromagnetic shielding effect is achieved in wide frequency band, which promotes and improves the design and production level of high quality transparent shielding materials, and can be widely used in the electromagnetic shielding design and reinforcement of all kinds of optical windows.

Description

technical field [0001] The invention relates to the field of design and preparation of electromagnetic shielding materials, in particular to a composite structure of broadband light-transmitting shielding materials. Background technique [0002] Among the many electromagnetic shielding materials, they should be selected according to different classifications of uses. For conventional shielding requirements, electromagnetic shielding materials with good electrical conductivity and magnetic permeability can be selected. However, for the special shielding requirements of various optical windows, such as personnel lighting windows, displays, optical sensors, etc., it is necessary to choose transparent shielding materials. As a good conductor, metal has always been the first choice for shielding materials, but due to the opacity of metal, it cannot meet the requirements of light transmission. In the early days, the screen structure was generally used as a light-transmitting shi...
