Embodiment 1

[0226] 89.5 parts by mass of PPS, 5 parts by mass of PPE, 5 parts by mass of modified elastomer 1, and 0.5 parts by mass of a silane coupling agent were uniformly mixed with a drum mixer to obtain a mixture.

[0227] Next, this mixture was injected|thrown-in to the twin-screw extruder (The Nippon Steel Works make, "TEX-30α") ​​equipped with a belt. Then, it was melt-extruded under conditions of a discharge rate of 20 kg / hr, a screw speed of 300 rpm, and a set temperature of 300° C., discharged in a strand form, cooled with water at a temperature of 30° C., and then cut to produce a resin composition.

[0228] Next, this resin composition was injected|thrown-in to the single-screw extruder of full flight screw, and it melt|melted on the condition of 280-300 degreeC. After the molten resin composition was extruded from the T-die, it was cooled in close contact with a cooling roll set at 40° C. to produce an unstretched sheet.

[0229] Next, the prepared unstretched sheet was bi...

Embodiment 2

[0234] The compounding quantity of PPS was made into 86.5 mass parts, and except having added 3 mass parts of styrene-type resin 1 further, it carried out similarly to Example 1, and manufactured the flat cable.

[0235] In addition, when the constituent components of the insulating film were analyzed by the same method as in Example 1, it was found that the particles of PPE were dispersed in the matrix of PPS. It should be noted that the modified elastomer 1 exists alone as dispersed particles, or exists at the interface between the matrix and the PPE particles.

Embodiment 3～5

[0237] A flat cable was produced in the same manner as in Example 2, except that the compounding amounts of PPS, PPE, modified elastomer 1, styrene-based resin 1, and the silane coupling agent were changed as shown in Table 2.

[0238] In addition, when the constituent components of the insulating film were analyzed by the same method as in Example 1, it was found that the particles of PPE were dispersed in the matrix of PPS. It should be noted that the modified elastomer 1 exists alone as dispersed particles, or exists at the interface between the matrix and the PPE particles.

Abstract

Provided are an adhesive film, a flat cable, and an insulating film excelling in toughness and adhesive strength, and capable of achieving a lower dielectric constant and a lower dielectric loss tangent. More specifically, an insulating film 4 is used in a flat cable 1. The insulating film 4 is formed from a resin composition containing: a polyarylene sulfide-based resin (A); a polyphenylene ether-based resin (B); and a modified elastomer (C) having a reactive group capable of reacting with the polyarylene sulfide-based resin (A) and / or the polyphenylene ether-based resin (B). In the resin composition, the content of the polyarylene sulfide-based resin (A) is 50-93 mass%, and the content of the polyphenylene ether-based resin (B) is 3-40 mass%.

Description

technical field [0001] The present invention relates to an insulating film, an adhesive film and a flat cable. Background technique [0002] In recent years, in the field of flexible printed wiring board (FPC) and flexible flat cable (FFC), with the development of cloud technology, IoT (Internet of Things), etc., technological improvement of automatic driving of automobiles, electric The development of automobiles and hybrid vehicles requires a large amount of data processing and high-speed transmission. [0003] In addition, in order to realize the weight reduction and compactness of vehicles, the technology of integrating the main body, peripheral components, cables, etc. (i.e., modularization) is advancing in electronic equipment for vehicles, and FFCs that are thin and have high wiring density are desired. . [0004] FFC is manufactured by laminating flat-angle conductors arranged in parallel with two upper and lower insulating films with adhesive layers. For the insu...
