no. 2 Embodiment approach

[0232] Next, refer to image 3 A second embodiment of the cable of the present invention will be described. image 3 It is a cross-sectional view showing an optical fiber cable which is a second embodiment of the cable of the present invention.

[0233] Such as image 3 As shown, the cable 20 includes two tensile members 22 and 23 , an optical fiber 24 as a transmission medium, and an insulator 25 covering them. Here, the optical fiber 24 is provided to penetrate the insulator 25 . Here, the insulator 25 is composed of an insulating portion covering the optical fiber 24 , and the insulating portion is composed of the flame-retardant resin composition constituting the first insulating layer 3 and the second insulating layer 4 in the first embodiment of the cable.

[0234] Here, the above-mentioned flame-retardant resin composition has excellent flame retardancy and can suppress separation of the flame retardant. Therefore, the insulator 25 composed of the above-mentioned fl...

Abstract

A flame-retardant resin composition includes a base resin (A) including a polyolefin resin, and a flame retardant. The flame retardant includes an organic phosphorus compound (B) and a hindered amine compound (C), the organic phosphorus compound (B) being represented by general formula (1), and the hindered amine compound (C) having a group represented by general formula (2). (In general formula (1), a hydrocarbon group which may have a substituent is represented, and the substituents may be the same or different.) (In general formula (2), R1-R4 each independently represent a C1-8 alkyl group, and R5 represents a C1-50 alkyl group, a C5-12 cycloalkyl group, a C7-25 aralkyl group, or a C6-12 aryl group.).

Description

technical field [0001] The present invention relates to a flame retardant resin composition, a flame retardant resin composition for cables, a cable using the same, a molded body, a flame retardant masterbatch, and a flame retardant. Background technique [0002] Polyolefin resins have excellent mechanical properties and are widely used in building materials, packaging materials, OA equipment, automotive parts, cables, etc. Since polyolefin resin is a flammable substance, it is used in a state where various flame retardants such as halogen-based flame retardants, phosphorus-based flame retardants, and metal hydrate-based flame retardants are added. However, although halogen-based flame retardants can impart excellent flame retardancy, they tend to generate toxic gas and smoke when burned, and are subject to regulation depending on the country. Therefore, in recent years, flame-retardant resin compositions using non-halogen-based flame retardants have been demanded. As such...
