Problems solved by technology

[0005] However, according to conventional techniques, the content of polypropylene is relatively high, and the composition of the hydrogenated block copolymer is also not specified
Therefore, in the case where the insulating layer of the insulated wire is made thinner in order to facilitate or improve wiring and weight reduction, it cannot give satisfactory scrap abrasion resistance and cannot satisfy the requirements of the insulated wire. Other appropriate properties such as gasoline resistance, flame retardancy and low temperature resistance listed in standard ISO (International Organization for Standardization) 6722

Embodiment Construction

[0023] As described above, the flame retardant resin composition according to the present invention contains: (A) 100 parts by weight of the base resin and (B) 10 to 30 parts by weight of the condensed phosphoric acid ester. The base resin (100 parts by weight) contains: (A1) 40 to 70 parts by weight of polyphenylene ether, (A2) 10 to 40 parts by weight of polyolefin, and (A3) 10 to 30 parts by weight of styrene ethylene butene styrene Block copolymer (styrene ethylene butylene styrene block copolymer).

[0024] The polyphenylene ether (PPE) that can be used in the present invention is available from companies such as Mitsubishi Engineering Plastics. The polyphenylene ether may be present in an amount of 40 parts by weight to 70 parts by weight in 100 parts by weight of the base resin. In the case where the polyphenylene ether is present in an amount of less than 40 parts by weight in 100 parts by weight of the base resin, it will be difficult to achieve desired abrasion resi...

Abstract

The objective of the invention is to provide flame retardant composition which is capable of providing thinner insulating covering or insulating layer for a vehicular insulated electrical wire, and meets abrasion resistance, gasoline resistance, flame retardant properties, and low temperature resistance requirements. To attain the objective, there is provided a flame retardant composition, which contains 100 parts by weight of (A) base resin, containing (A1) from 40 to 70 parts by weight of polyphenylene ether, (A2) from 10 to 40 parts by weight of polyolefin, and (A3) from 10 to 30 of styrene ethylene butylene styrene block copolymer; and (B) from 10 to 30 parts by weight of condensed phosphoric acid ester.

Description

technical field [0001] The present invention relates to an insulated wire exhibiting significantly enhanced abrasion resistance, which may be particularly suitable for use in vehicle applications, and a flame retardant composition for the manufacture of an insulating covering for the insulated wire. Background technique [0002] Insulated wires placed on vehicles (eg, vehicle insulated wires) are often required to meet a high degree of abrasion resistance. This is because vehicle insulated wires are often placed inside automobiles where a lot of vibration occurs and where there is only a small space. [0003] In addition, in particular, vehicle insulated wires placed in an engine or the like need to meet the requirements of flame retardancy, gasoline resistance, and low temperature resistance. Furthermore, in order to facilitate or enhance wiring and weight reduction, the insulating covering of the insulated wire needs to be made thinner. [0004] In JP H11-147980(A), ther...
