Conductive fabric and manufacturing method thereof

Abstract

The invention provides a conductive fabric which comprises a conductive fiber fabric coated with a metal coating layer and a conductive adhesive layer. The conductive fabric further comprises a hard adhesive layer arranged between the conductive fiber fabric and the conductive adhesive layer, wherein the hard adhesive layer is prepared from viscous resin, a conductive agent and a curing agent. Compared with a conductive fabric only comprising a conductive fiber fabric and a conductive adhesive, the hardness of the conductive fabric is increased by adding the hard adhesive layer, and the edge of the conductive fabric is prevented from warping and rolling when being heated. In addition, the viscous resin can be filled into gaps of the fiber fabric before being cured, the conductive adhesive layer is prevented from recessing concavely, a fabric sizing rate is reduced, and the viscosity of an adhesive face is improved; meanwhile, the conductive agent in the hard adhesive layer has an effect of electrically connecting the conductive adhesive layer and the metal coating layer; as the conductive fiber fabric is covered by the hard adhesive layer, adhesion force of the conductive fiber fabric is strong, and a resistance value is relatively stable. Therefore, the viscosity of the conductive fabric disclosed by the invention is improved, and the conductive property is not affected.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a conductive cloth and a manufacturing method thereof. Background technique [0002] Since the liquid crystal module is prone to static electricity during production and production, it is necessary to ground the panel or S-board (SourceBoard, source driver board) and the backplane. Usually, the S-board is bonded and fixed on the backplane through a conductive cloth. The S board is electrically connected to the backplane through the conductive cloth to achieve grounding. Conventional conductive cloth, such as figure 1 As shown, it includes release paper 11, acrylic conductive adhesive 12, and conductive fiber cloth 13. [0003] Due to the heating of the display module during use, the edge of the conductive cloth is warped and curled, which easily leads to the loosening of the S board. From the failure rate data of the whole machine on-line, the problem of conductive cloth wa...

AI Technical Summary

Problems solved by technology

The optimization of traditional process parameters has a limited effect on the adhesive strength of the glue

However, simply relying on increasing the viscosity of the conductive cloth itself to solve the warping problem will weaken the conductive performance of the conductive cloth, because the viscosity and conductive performance of the conductive cloth itself are mutually restricted.
