く要望されるようになってきた。[Prior Art] Polyolefins, which have excellent electrical insulation properties, have been widely used as insulating materials and sheath materials for electric wires and cables. As a recent trend, there has been a strong demand for flame retardancy to be imparted to electric wires and cables for vehicles and ships, and electric wires for wiring inside panels and aircraft.

る。As a method of making polyolefin flame retardant, a method of mixing a halogen-containing compound, a phosphorus-containing compound, etc. has generally been adopted. However, these produce a large amount of smoke when burned, causing problems such as corrosivity to equipment and toxicity to the human body. In particular, recently there has been a demand for not generating such halogen-based gas from a safety standpoint.
この様な情勢を踏まえ、発煙性、有毒性の非常に少ない
無機系難燃剤が注目されるようになってきた。なかでも
、水酸化アルミニウムは最も代表的な無機系難燃剤であ
る。In light of this situation, inorganic flame retardants with extremely low smoke generation and toxicity are attracting attention. Among them, aluminum hydroxide is the most typical inorganic flame retardant.

。Aluminum hydroxide is H8(CH2)n5i(OR)
By using a surface treated with mercaptosilane represented by 3 [n: natural number, R: alkyl group], water absorption and moisture absorption can be suppressed and electrical characteristics can be improved. The content of aluminum hydroxide surface-treated with mercaptosilane is 50 parts by weight per 100 parts by weight of polyolefin.
The content should be in the range of ~500 parts by weight; if it is less than 50 parts by weight, the desired flame retardance cannot be imparted, and if it exceeds 500 parts by weight, the processability will be significantly reduced and extrusion molding will become difficult.
