Abstract

The invention discloses a high-viscosity hot-melt adhesive film and a preparation method thereof, comprising an insulating film, a pre-coat layer and an adhesive layer, the pre-coat layer is arranged between the insulating film and the adhesive layer; according to the quality The number of parts, the raw materials of the adhesive layer include 22.5 to 43.5 parts of saturated polyester resin A, 9 to 25.5 parts of saturated polyester resin B, 40 to 45 parts of flame retardant, 2 to 10 parts of high-viscosity metal strength resin, 0.2 ~1 part curing agent and 9~14 parts filler. Increase the high-viscosity metal-strength resin, which has a high glass transition temperature and a high softening point temperature. It can be used in conjunction with saturated polyester resin A and saturated polyester resin B to maintain the metal-bonding force of the hot-melt adhesive film at a high level for a long time. And other performance will not be reduced.

Description

technical field [0001] The invention relates to the field of film manufacturing, in particular to a high-viscosity hot-melt adhesive film and a preparation method thereof. Background technique [0002] FFC cable, also known as Fexibe Flat Cable (FFC), is a flexible flat cable. It is a new type of data cable made of tinned flat copper wires sandwiched between upper and lower layers of insulating materials. It is soft and flexible. Bending and folding, thin thickness, small body, simple connection, easy disassembly, and easy to solve electromagnetic shielding (EMI), etc., are currently widely used in signal transmission and boards of various electronic products such as plotters, scanners, audio, LCD appliances, etc. Interconnections are almost ubiquitous in modern electronic devices. [0003] The existing FFC cable realizes the hot-melt bonding between the insulating material and the tinned flat copper wire through the hot-melt adhesive film. Implement hot-melt bonding betwe...
