Ba-Zn-based complex fatty acid salts and thioether-based antioxidants are known as heat stabilizers and antioxidants, respectively, but by using them in combination, excellent heat resistance, particularly resistance to heat aging, can be obtained. . The Ba-Za-based complex fatty acid salt in the present invention is a mixture of a barium-based fatty acid salt and a zinc-based fatty acid salt, and as the barium-based fatty acid salt, barium stearate or barium laurate is preferable, and the zinc-based fatty acid salt is used. Is preferably zinc stearate or zinc laurate,
These barium-based fatty acid salts and zinc-based fatty acid salts may be used in any combination of one or more. The mixing ratio of barium fatty acid salt and zinc fatty acid salt is 1: 1 ~
0.7: 0.3 is preferable. Such a Ba-Zn complex fatty acid is used in an amount of 1 to 15 parts by weight per 100 parts by weight of the chlorinated polyethylene composition. If it is less than 1 part by weight, the heat resistance is not improved, and if it is more than 15 parts by weight, the workability is lowered and the stabilizer blows out on the surface of the product, so-called blooming occurs.

It is preferable to add an organic flame retardant. In addition, known fillers such as calcined clay and stabilizers may be added. Further, a cross-linking agent and a cross-linking aid are appropriately added depending on the cross-linking method. As the crosslinking method, irradiation of ionizing radiation, vapor crosslinking by addition of peroxide, water crosslinking by silane grafting and the like can be arbitrarily selected. In order to use the composition of the present invention as a sheath for a lead wire, a kneading is performed at a resin temperature of about 120 ° C. by a roll mill, a Banbury mixer, etc., and after pelletization, a desired extruding temperature of 90 ° C. to 100 ° C. is extruded by an extruder. Molded as a cable sheath and crosslinked.
