この発明は、優れた難燃性と機械的特性を併せ有する難

ているため、多用されているが、燃焼し易いと言う欠点
のために、従来からその難燃化についての研究が行われ
ている。Conventionally, polyolefin resins such as polyethylene, polypropylene, ethylene-propylene copolymer, and ethylene-ethyl acrylate copolymer have been used as coating materials and connection materials for electric wires and cables because of their excellent flexibility and processability. Although it is widely used, it has the drawback of being easily combustible, so research has been carried out to make it flame retardant.

。One such flame retardant technique is to mix halogen-based flame retardants, but resin compositions containing halogen-based flame retardants generate a large amount of soot when burned, and are toxic and corrosive. The problem is that hydrogen halide gas is generated.

じる。As a solution to these difficulties, a method of blending a metal hydrate such as magnesium hydroxide or aluminum hydroxide with a polyolefin resin has been considered. However, in this flame retardant method, the flame retardant effect of metal hydrate is weak, so a relatively large amount must be added, which leads to a decrease in the tensile strength and cold resistance of the resin composition. This will cause inconvenience.

It is a polysiloxane having a structure shown by the formula (1) or (II) in the figure, and it is sufficient that the molecule contains either or both of a hydroxyl group and a carboxyl group. Specific examples of this include carboquine-modified/licon oil and alcohol-modified silicone oil. The carboxy-modified silicone turnip oil is preferably one having a viscosity (at 25° C.) of about 2,500 to 3,500 centistics and a carboxyl group content of about 3,500 to 4,000. In addition, as alcohol-denatured/refoon oil, its viscosity (at 25°C) is approximately 100 to 150 centistokes, and the hydroxyl group (○H) content is 1 to 2%.
(weight ratio) is preferable.

If it is less than 0.2 parts by weight, no improvement in flame retardancy can be obtained, and if it exceeds 20 parts by weight, the extrusion processability of the resin composition will be significantly reduced, and the flame retardant effect will reach a ceiling, making it uneconomical. .
