Abstract
Official abstract text for this publication.
Provided are a rubber composition for a flame-retardant hose, the rubber composition including from 20 to 45 parts by mass of aluminum hydroxide and greater than 65 parts by mass of a carbon black per 100 parts by mass of a rubber component containing at least chloroprene rubber, and the flame-retardant hose including a rubber layer formed using the rubber composition for a flame-retardant hose.
First claim
Opening claim text (preview).
1 . A rubber composition for a flame-retardant hose, the composition comprising from 20 to 45 parts by mass of aluminum hydroxide and greater than 65 parts by mass of a carbon black, per 100 parts by mass of a rubber component containing at least chloroprene rubber. 2 . The rubber composition for a flame-retardant hose according to claim 1 , wherein the rubber component further comprises a diene rubber other than the chloroprene rubber. 3 . The rubber composition for a flame-retardant hose according to claim 2 , wherein the diene rubber is styrene-butadiene rubber. 4 . The rubber composition for a flame-retardant hose according to claim 1 , wherein a content of the chloroprene rubber is not less than 70 parts by mass per 100 parts by mass of the rubber component. 5 . The rubber composition for a flame-retardant hose according to claim 1 , wherein a content of the carbon black is from 66 to 90 parts by mass per 100 parts by mass of the rubber component. 6 . The rubber composition for a flame-retardant hose according to claim 1 , further comprising a silica, wherein a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component. 7 . A flame-retardant hose comprising a rubber layer formed using the rubber composition for a flame-retardant hose described in claim 1 . 8 . The rubber composition for a flame-retardant hose according to claim 2 , wherein a content of the chloroprene rubber is not less than 70 parts by mass per 100 parts by mass of the rubber component. 9 . The rubber composition for a flame-retardant hose according to claim 3 , wherein a content of the chloroprene rubber is not less than 70 parts by mass per 100 parts by mass of the rubber component. 10 . The rubber composition for a flame-retardant hose according to claim 2 , wherein a content of the carbon black is from 66 to 90 parts by mass per 100 parts by mass of the rubber component. 11 . The rubber composition for a flame-retardant hose according to claim 3 , wherein a content of the carbon black is from 66 to 90 parts by mass per 100 parts by mass of the rubber component. 12 . The rubber composition for a flame-retardant hose according to claim 4 , wherein a content of the carbon black is from 66 to 90 parts by mass per 100 parts by mass of the rubber component. 13 . The rubber composition for a flame-retardant hose according to claim 2 , further comprising a silica, wherein a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component. 14 . The rubber composition for a flame-retardant hose according to claim 3 , further comprising a silica, wherein a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component. 15 . The rubber composition for a flame-retardant hose according to claim 4 , further comprising a silica, wherein a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component. 16 . The rubber composition for a flame-retardant hose according to claim 5 , further comprising a silica, wherein a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component.
