与する試みが種々行われている。As the insulator for insulated wires, polyethylene is widely used (as is well known), which has excellent electrical properties, water distribution properties, cold resistance, and is easy to add. In order to improve the insulation properties, various attempts have been made to impart flame retardancy to ethylene.

う。In general insulated wires, Roe plasticized polyvinyl chloride is used for the base material, taking into account the properties required for practical use, processing work, flexibility, etc. of the base material. Polyvinyl vinyl itself is self-dissipating, but the flexible T/I/V price is 20-40%.
When mixed with heavy duty plasticizer, it becomes more combustible. As a measure against flame retardancy f1 of plasticized polyvinyl chloride, it is known to mix 1h dichloroparaffin, phosphorus-based IJ compound with mini antimony oxide, and according to this, good flame retardance f[ It is also known that l,';j can be obtained. However, in the case of insulated wires that use polyethylene as an insulator, even if such materials are mixed, it will not be possible to provide sufficient flame retardancy. To determine the 11+ value of the flame retardancy of an insulated wire, the flame retardancy test method θ described in Tb:G: 383 is adopted. The gist of this method is
A flame from a gas bar was applied directly to the insulated wire for 20 minutes, and the burn distance and afterflame were observed. When an insulated wire coated with plasticized polyvinyl chloride from the above method is tested using this test horn θ, it is found that the base material burns and disappears due to contact with the flame, or cracks or shatters occur. As a result, the polyethylene of the internal insulator ignited and burned.

られる。Ethylene-vinyl acetate copolymer and chlorinated polyethylene have the property of softening and melting when exposed to flame, and the gas generated during combustion acts as a foaming agent to form a foam. Foaming phenomenon occurs even when these are used alone, but it was revealed that the foaming ratio is improved when these are used. When added, lead chloride is produced, which promotes the use of dehydrochlorination and improves carbonization, resulting in a strong foamed carbonized layer.
