RUBBER COMPOSITION AND CONVEYOR BELT

摘要

Provided are: a rubber composition that has excellent adhesiveness to galvanized steel cords and that has improved flame retardancy and cold resistance; and a conveyor belt. This rubber composition is a rubber composition that includes: a rubber component including butadiene rubber, chloroprene rubber, and natural rubber; an organic cobalt salt; rosin or a rosin derivative; and an organochlorine compound. The content of said butadiene rubber is from 5 parts by mass to 20 parts by mass inclusive per 100 parts by mass of said rubber component. The content of said chloroprene rubber is from 20 parts by mass to 65 parts by mass inclusive per 100 parts by mass of said rubber component. The content of said organic cobalt salt is from 0.2 parts by mass to 1.0 part by mass inclusive per 100 parts by mass of said rubber component when the mass of said organic cobalt salt is converted to that of cobalt. The content of said rosin or rosin derivative is from 2 parts by mass to 9 parts by mass inclusive per 100 parts by mass of said rubber component. The content of said organochlorine compound is from 5 parts by mass to 35 parts by mass inclusive per 100 parts by mass of said rubber component.
