Abstract

Disclosed is a flame retardant resin composition comprising: a polyolefin resin; a silicone-based compound blended at a ratio of 3 parts by mass or more and 20 parts by mass or less relative to 100 parts by mass of the polyolefin resin; a fatty acid containing compound blended at a ratio of 5 parts by mass or more and 20 parts by mass or less relative to 100 parts by mass of the polyolefin resin; calcium carbonate blended at a ratio of 10 parts by mass or more and less than 100 parts by mass relative to 100 parts by mass of the polyolefin resin; and aluminum hydroxide blended at a ratio of 5 parts by mass or more and 60 parts by mass or less relative to 100 parts by mass of the polyolefin resin.

First claim

1 . A flame retardant resin composition comprising:
a polyolefin resin; a silicone-based compound blended at a ratio of 3 parts by mass or more and 20 parts by mass or less relative to 100 parts by mass of the polyolefin resin; a fatty acid containing compound blended at a ratio of 5 parts by mass or more and 20 parts by mass or less relative to 100 parts by mass of the polyolefin resin; calcium carbonate blended at a ratio of 10 parts by mass or more and less than 100 parts by mass relative to 100 parts by mass of the polyolefin resin; and aluminum hydroxide blended at a ratio of 5 parts by mass or more and 60 parts by mass or less relative to 100 parts by mass of the polyolefin resin.

2 . The flame retardant resin composition according to claim 1 , wherein aluminum hydroxide is blended at a ratio of 5 parts by mass or more and 25 parts by mass or less relative to 100 parts by mass of the polyolefin resin.

3 . The flame retardant resin composition according to claim 1 , wherein the silicone-based compound is blended at a ratio of 3 parts by mass or more and 10 parts by mass or less relative to 100 parts by mass of the polyolefin resin.

4 . The flame retardant resin composition according to claim 1 , wherein the fatty acid containing compound is magnesium stearate or calcium stearate.

5 . The flame retardant resin composition according to claim 1 , wherein the composition consists of the polyolefin resin, the silicone-based compound, the fatty acid containing compound, the inorganic flame retardant, and at least one additive selected from the group consisting of an oxidation inhibitor, an ultraviolet ray deterioration inhibitor, a processing aid, a coloring agent, and an anti-static agent.

6 . The flame retardant resin composition according to claim 5 , wherein
the oxidation inhibitor is formed of at least one selected from the group consisting of a phenol-based oxidation inhibitor, an amine-based oxidation inhibitor, a sulfur-based oxidation inhibitor, a phosphorus-based oxidation inhibitor, a hydrazine-based oxidation inhibitor, an amide-based oxidation inhibitor, phosphoric acid, and citric acid, the ultraviolet ray deterioration inhibitor is formed of at least one selected from the group consisting of a benzophenone-based ultraviolet ray deterioration inhibitor, a salicylate-based ultraviolet ray deterioration inhibitor, a benzotriazole-based ultraviolet ray deterioration inhibitor, an acrylonitrile-based ultraviolet ray deterioration inhibitor, a metal complex salt-based ultraviolet ray deterioration inhibitor, and a hindered amine-based ultraviolet ray deterioration inhibitor, the processing aid is formed of at least one selected from the group consisting of a hydrocarbon-based processing aid, a fatty acid-based processing aid, a fatty acid amide-based processing aid, an ester-based processing aid, an alcohol-based processing aid, a metal soap, and wax, the coloring agent is formed of at least one selected from the group consisting of an inorganic pigment, an organic pigment, a dye, and carbon black, and the anti-static agent is formed of at least one selected from the group consisting of a cationic active agent, an anionic active agent, a non-ionic active agent, and an amphoteric active agent.

7 . The flame retardant resin composition according to claim 5 or 6 , wherein
the additive is blended at a ratio of less than 1 part by mass relative to 100 parts by mass of the polyolefin resin.

8 . A cable comprising an insulated wire which has a conductor and an insulating layer covering the conductor, wherein the insulating layer is formed of the flame retardant resin composition according to claim 1 .

9 . A cable having a conductor, an insulating layer covering the conductor, and a sheath covering the insulating layer, wherein at least one of the insulating layer and the sheath is formed of the flame retardant resin composition according to claim 1 .

10 . A cable having a sheath and an optical fiber provided on the inner side of the sheath or provided to penetrate the sheath, wherein the sheath is formed of the flame retardant resin composition according to claim 1 .
