高いハロゲン系難燃剤を混和することが種々検討されて
きている。As a recent trend, there is a strong demand for flame retardancy in electric wires and cables for nuclear power plants, and electric wires for wiring inside panels and machines, and various studies have been conducted to incorporate halogen-based flame retardants with high flame retardant effects.
［発明が解決しようとする問題点］
しかし、ハロゲン系難燃剤は、樹脂またはゴムとの混練
加工時に凝集しやす（、分散性に問題がある。[Problems to be Solved by the Invention] However, halogen flame retardants tend to aggregate during kneading with resin or rubber (and have problems in dispersibility).
本発明は、分散性を向上できる難燃性電気絶縁組成物の
提供を目的とするものである。An object of the present invention is to provide a flame-retardant electrical insulating composition that can improve dispersibility.

なることを特徴とするものである。[Means for solving the problems] The flame-retardant electrical insulation composition of the present invention comprises resin or rubber,
A product obtained by immobilizing a halogen-based flame retardant with an average particle size of 1/10 or less of the powdered resin or powder rubber on a powdered resin or powdered rubber with an average particle size of 1000 μm or less, or a halogen with an average particle size of 1000 μm or less It is characterized in that it is made by admixing a powdered resin or powdered rubber with an average particle diameter of one-tenth or less of the halogenated flame retardant into a fixed flame retardant.

うな固定化処理により金属水酸化物同士の凝集を抑える
ことができ、分散性を著しく改善できる。In the present invention, immobilization treatment refers to stirring the powdered resin or powdered rubber and the halogenated flame retardant in a mill, thereby mechanochemically adhering the halogenated flame retardant to the surface of the powdered resin or powdered rubber, and then finely pulverizing the halogenated flame retardant. This refers to the process of driving and fixing halogen-based flame retardants into powdered resin or powdered rubber using the impact force and frictional force of a machine, etc. Such immobilization treatment can suppress aggregation of metal hydroxides and significantly improve dispersibility.
なお、本発明においては上記とは逆にハロゲン系難燃剤
の表面に粉末樹脂または粉末ゴムを付着させ、固定化処
理することによっても分散性を改善できる。In the present invention, contrary to the above, dispersibility can also be improved by attaching powdered resin or powdered rubber to the surface of the halogenated flame retardant and performing a fixation treatment.

実施例および比較例について難燃性および分散性を評価
し、その結果を第１表の下欄に示した。なお、評価は次
に基づいて行った。The flame retardance and dispersibility of Examples and Comparative Examples were evaluated, and the results are shown in the lower column of Table 1. Note that the evaluation was performed based on the following.
分散性：製造した絶縁電線１０ｃｍの外観を倍率２０倍
の顕微鏡で観察し、１ｍｍを越える大きさの凝集物がｌ
Ｏ個／１０ｃｍ以上存在場合を不良とし、それ以下の場
合を良好とした。Dispersibility: The appearance of 10 cm of the manufactured insulated wire was observed under a microscope with a magnification of 20 times, and aggregates larger than 1 mm were found.
A case where O pieces/10 cm or more were present was judged as poor, and a case where it was less than that was judged as good.
難燃性： ＪＩＳＣ３００４に基づき、水平に保った絶
縁電線をバーナで燃焼後、１分以内に消えれば合格であ
り、１分以上燃えるものは不合格である。Flame retardancy: Based on JISC3004, if the insulated wire held horizontally is burned in a burner, it passes if it disappears within 1 minute, and if it burns for more than 1 minute, it is rejected.
