The present invention relates to an insulating composition.

件として採用することが一般的となった。The materials conventionally used as insulation and sheathing for electric wires and cables are all flammable, and in the event of a fire, the fire will travel through the wiring system of the highly integrated electric wires and cables. There are many cases where the demand for flame-retardant electric wires and cables is increasing rapidly. As a standard for flame retardancy, the IEEE (Institute of Electrical and Electronics Engineers) Standard 383 VTFi' Cf1t-ReiFff1EII
), it has become common to adopt the condition of flame retardancy as passing a multi-strand flammability test that simulates the actual installation conditions of electric wires and cables.

おそれもある。However, such flame-retardant electrical insulation compositions generate a large amount of nonflammable halogen-based scum in the event of a fire, thereby blocking oxygen around electric wires and cables and preventing combustion. Although it exhibits sufficient flame retardant properties, many of the halogen-based gases that are generated are toxic, such as hydrogen chloride, and the visibility is poor because it generates a large amount of smoke containing such toxic gases. This may hinder evacuation and firefighting activities in the event of a fire, or the toxic residue may adversely affect the human body, causing a primary disaster.Furthermore, halogen-based gases may react with moisture in the air, causing halogen-based There is also a risk that it will turn into hydrochloric acid and corrode the switchboard.

性電気絶縁組成物が提案され、ン主目を集めている。For this reason, a flame-retardant electrical insulation composition has been proposed that emphasizes safety in the event of a fire by mixing inorganic hydroxides such as aluminum hydroxide and magnesium hydroxide in place of the halogen-based compounds and phosphorus-based compounds. It is attracting a lot of attention.

特性が著しく低へするという問題がある。[Problems to be Solved by the Invention] The flame-retardant composition containing the above-mentioned inorganic hydroxide utilizes the endothermic action of the hydroxide when it releases crystal water in the event of a fire as a flame-retardant effect. However, these inorganic hydroxides have extremely low flame retardancy compared to the halogen-based and phosphorus-based compounds mentioned above, so they have to be mixed in larger amounts. As a result, there is a problem in that mechanical properties such as tensile properties and scratch resistance are significantly reduced.
