Abstract

PURPOSE:To provide a flame-retardant composition with an improved acid resistance. CONSTITUTION:A flame-retardant composition, provided with flame retardancy and improved in acid resistance, is prepared by grinding a natural mineral containing magnesium hydroxide as the main component, subjecting the surface of the powdered mineral to a surface treatment composed primarily of at least one component selected from among a fatty acid, metallic salt of a fatty acid, silane coupling agent and titanate coupling agent, and then adding a plastic or rubber thereto.

The flame-retardant composition using this as flame-retardant, when left in high-humidity air, causes precipitation of magnesium carbonate obtained by reacting carbon dioxide gas in the air and magnesium hydroxide on the material surface, or immersion in an acidic solution. Then, there was a problem that magnesium hydroxide was eluted and the acid resistance was poor.
