水溶液に溶は出し、難燃性が著しく低下するという問題
があった。In recent years, there has been a strong demand for flame-retardant electrical cables and connection cases that do not emit toxic and corrosive halogen gases. As non-halogen flame retardant materials for cables and the like, materials in which a polymer such as a polyolefin thread resin is filled with a large amount of water-use inorganic material such as magnesium hydroxide are widely used. This inorganic photonic agent is usually treated with a fatty acid in order to improve its dispersibility in the resin, but this treated inorganic photonic agent is difficult to dissolve in acidic aqueous solutions. There was a problem in that the flammability was significantly reduced.

性が著しく劣ることがわかった。Example 7 A material obtained by kneading 100 parts by weight of the pace polymer of Example 6 with 100 parts by weight of aluminum hydroxide and 2.6 parts by weight of carbon black was evaluated for acid resistance and flame retardancy. As a result, it has good flame retardancy with an oxygen index of 27, the weight loss after immersion in sulfuric acid is as small as CL1, and the oxygen index is 27 compared to the initial value.
It was found that it is a good acid-resistant flame retardant material.
C,0 Comparative Example 4 A material obtained by kneading 100 parts by weight of the ethylene-vinyl acetate copolymer of Example 6 with 100 parts by weight of magnesium hydroxide and 2.6 parts by weight of carbon black was evaluated, and the initial oxygen index was 28, which was good. However, the weight loss after immersion in sulfuric acid was 36
It was found that the weight was large, and the oxygen index decreased to 20, indicating that the acid resistance was extremely poor.
