Problems solved by technology

As a result, a blend system satisfying both battery fluid resistance and flame retardancy was found, but this caused adverse effects, namely the problem of deterioration of low temperature resistance and wear resistance
[0004] In addition, resin compositions that provide flame retardancy have been known (see, for example, Patent Documents 3 to 5), but none of them can simultaneously satisfy flame retardancy, battery fluid resistance, low temperature resistance, abrasion resistance, and peeling performance

[0054] (Production of electric wires (cables) for automobiles)

[0055] The compositions used in Examples were prepared by kneading the respective components in the blending amounts (parts by mass) given in Tables 1 to 5 using a kneader or a screw type kneader, and then by using these compositions, Load them into an extruder (diameter 60mm, L / D=24.5, FF screw) and extrude them onto conductors at an extrusion rate of 500m / min and an extrusion temperature of 230°C to produce automotive electric wire. The respective components in Tables 1 to 5 are as follows:

Abstract

To provide an electric cable that can satisfy flame retardancy and battery fluid resistance in the CHFUS region provided in ISO 6722 and also satisfy low-temperature resistance, wear resistance, and peelability by using a halogen-containing flame retardant. An electric cable in which a coat layer is formed of a non-crosslinked resin composition that includes (A) 40 to 84 parts by mass of a polypropylene homopolymer, (B) 1 to 10 parts by mass of a polypropylene-based modified resin, (C) 10 to 30 parts by mass of a polyolefin-based copolymer, and (D) 5 to 20 parts by mass of an olefin-based elastomer and further includes 1 to 45 parts by mass of a metal hydroxide and 10 to 80 parts by mass of a halogen-containing flame retardant based on 100 parts by mass of the resins (A), (B), (C), and (D) in total.

Description

technical field [0001] The present invention relates to an electrical cable, and in particular, to an electrical cable capable of satisfying flame retardancy and battery fluid resistance in the CHFUS region specified in ISO6722, and also satisfying low temperature resistance and abrasion resistance. Background technique [0002] As an insulating resin composition for covering electric cables, especially electric wires for automobiles, there is known a resin composition for electric wire insulators in which 60 to 90 parts by mass of a metal hydroxide has been mixed with 100 parts by mass The basic resin is blended, the basic resin is composed of 55 parts by mass to 98 parts by mass of polyolefin polymer and the rest of polyamide, and the polyamide is a copolymer of polyamide 6 and polyamide 66 (See Patent Document 1). However, it has been proved that the resin composition has a problem that the amount of magnesium hydroxide added is too large, so that the resin composition c...
