Abstract

The invention discloses a hot-pressed insulating film and a flexible flat cable comprising the same. The invention provides the hot-pressed insulating film. The hot-pressed insulating film comprises a base material layer and an adhesive layer formed on the surface of the base material layer, the adhesive layer comprises the following raw materials in percentage by mass: 30-50% of saturated polyester resin A, 5-20% of saturated polyester resin B, 25-45% of a flame retardant, 5-10% of a curing agent, 0.01-0.1% of a curing accelerator, 0.1-1% of a dispersing aid, and 0.1-1% of a hydrolysis-resistant auxiliary agent. The glass transition temperature Tg of the saturated polyester resin A is 0-30 DEG C, and the acid value of the resin A is less than 3 KOHmg/g; the glass transition temperature Tg of the saturated polyester resin B is 40-120 DEG C; and the number-average molecular weight Mn of the saturated polyester resin A and the saturated polyester resin B is 5000-40000. The hot-pressed insulating film provided by the invention can meet long-term outdoor use requirements.

Description

technical field [0001] The invention specifically relates to a heat-pressed insulating film and a flexible flat cable comprising the insulating film. Background technique [0002] FFC (Flexible Cable Tape, the Chinese name is flexible flat cable) is an insulating hot-melt tape with PET as the base material and an extremely thin and thin tinned flat copper wire. It is made by hot pressing with an automatic rolling compound machine. It has the advantages of softness, random bending and folding, thin thickness, small size, simple connection, convenient disassembly, and easy solution to electromagnetic shielding (EMI). At present, it is widely used in the connection between the print head of various printers and the main board, the signal transmission and board connection of plotters, scanners, copiers, audio, LCD appliances, fax machines, various DVD players and other products. In modern electrical equipment, it is almost everywhere. [0003] In addition to the stable use of ...
