Abstract

The invention provides an insulating adhesive film for a flexible flat cable and a preparation method of the insulating adhesive film. The insulating adhesive film for the flexible flat cable comprises a base material layer and an adhesive layer, and the adhesive layer comprises the following components in parts by weight: 100 parts of epoxy resin, 20-80 parts of rubber, 50-150 parts of a flame retardant and 5-40 parts of a curing agent, wherein the epoxy resin is epoxy resin with two or more epoxy groups, and the mass of the epoxy resin with the two or more epoxy groups accounts for 20% or more of the total mass of the epoxy resin. The insulating adhesive film for the flexible flat cable is a thermosetting insulating adhesive film, and has the properties of high bonding strength, humidity and heat resistance and adhesive overflow resistance.

Description

technical field [0001] The invention belongs to the technical field, and relates to an insulating adhesive film and a preparation method thereof, in particular to an insulating adhesive film for flexible flat cables and a preparation method thereof. Background technique [0002] Flexible Flat Cable (FFC for short) has a structure in which several conductors arranged in parallel are laminated through an insulating substrate film and a resin adhesive layer. The size of the electronic product is reduced, the production cost is reduced, and the production efficiency is improved. [0003] Currently, flexible flat cables are used in electronic devices such as computers, scanners, mobile phones, printers, and copiers. In recent years, flexible flat cables have also been used in automotive electronics, engine compartments, and medical equipment in high-temperature and high-humidity environments. Therefore, higher requirements are put forward for the performance of the flexible fla...
