Embodiment 1

[0045] [Preparation of flame retardant]

[0046] The flame retardant (referred to as surface-treated magnesium hydroxide in Tables 1 and 2) was prepared as follows. While stirring magnesium hydroxide [manufacturer: NIHON KAISUI CO.LTD., industrial magnesium hydroxide (average particle size 10μm)] in a high-speed mixer at 200°C, use about A polypropylene having a weight average molecular weight of 1000 as a surface treatment agent [manufacturer: CLARIANT (JAPAN) KK, trade name: 6102] was gradually put into the mixer for 5 minutes. Then, the mixture was stirred for another 20 minutes. The content of the surface treatment agent in the flame retardant is 0.1% by mass.

[0047] In this embodiment, all weight average molecular weights are weight average molecular weights measured by GPC in terms of polystyrene. The measurement conditions of GPC are explained below.

Embodiment 2 to 7

[0057] Examples 2 to 7 (Table 1), Comparative Examples 1 to 7 (Table 2)

[0058] Except for setting the kind and content of the surface treatment agent contained in the flame retardant as described below, the flame retardant and the flame retardant resin composition were prepared in the same manner as in Example 1, thereby obtaining an insulated wire. The discharge amount of the produced flame-retardant resin composition was measured. Conduct cold resistance tests on insulated wires. The test results are shown in Tables 1 and 2.

Abstract

Provided are a flame retardant, a flame-retardant resin composition and an insulated wire that have favorable low-temperature characteristics, excellent cold resistance and high productivity. The insulated wire includes a conductor that is insulation-coated with the flame-retardant resin composition that contains the flame retardant that contains magnesium hydroxide and a surface treatment agent with which the magnesium hydroxide is surface-treated, wherein the surface treatment agent has a weight-average molecular weight of 10000 or less, and at least a base resin.

Description

Technical field [0001] The present invention relates to a flame retardant, a flame retardant resin composition, and an insulated wire, and more specifically, to a flame retardant, a flame retardant resin composition, and an insulated wire that can be favorably used in automobiles or electric / electronic equipment. Background technique [0002] Parts and insulating materials used in automobiles or electric / electronic equipment require various properties such as mechanical properties, flame resistance, heat resistance, and cold resistance. Generally, polyvinyl chloride compounds or compounds containing halogen-based flame retardants containing bromine atoms or chlorine atoms in the molecule are mainly used for these materials. [0003] The above-mentioned materials may generate a large amount of corrosive gas during incineration. Therefore, Patent Document 1 proposes a non-halogen flame-retardant material that does not generate corrosive gas. In addition, in Patent Document 2 to Pat...
