Rubber composition for flame-retardant hose, and flame-retardant hose
View Patent ↗The present technology provides a rubber composition for a flame-retardant hose, the composition containing a rubber component, a carbon black, and a silica, wherein the rubber component is only chloroprene rubber or only chloroprene rubber and styrene-butadiene rubber; and a flame-retardant hose including a rubber layer formed using the rubber composition for a flame-retardant hose.
1. A rubber composition for a flame-retardant hose, the composition comprising:
a rubber component, a carbon black, and a silica;
the rubber component being only chloroprene rubber and styrene-butadiene rubber; wherein
a content of the chloroprene rubber is not less than 70 parts by mass per 100 parts by mass of the rubber component; and
a content of the carbon black is greater than 65 parts by mass and not greater than 90 parts by mass per 100 parts by mass of the rubber component.
2. The rubber composition for a flame-retardant hose according to claim 1 , wherein
a content of the silica is from 5 to 25 parts by mass per 100 parts by mass of the rubber component.
3. A flame-retardant hose comprising a rubber layer formed using the rubber composition for a flame-retardant hose described in claim 1 .
