摘要： Anti-wear properties and tooth life in a toothed belt are improved by taking advantage of heat hardening of a treating agent used to treat the tooth cloth. The tooth cloth is treated with a resorcinol formaldehyde latex solution containing a mixture, at a weight ratio from 1:5 to 1:15, of a resorcinol formaldehyde solution containing resorcinol and formaldehyde at a molecular ratio from 1:1 to 1:3 and a latex solution containing carboxyl modified nitrile butadiene rubber and carboxyl modified hydrogenated nitrile rubber at a weight ratio from 4:6 to 1:9, and further containing carbon at a weight ratio of 1 to 10%. The solid content adhering onto the tooth cloth is from 5 to 30 weight %.

摘要： A toothed belt comprises an organic peroxide crosslinked hydrogenated nitrile rubber composition, having a co-crosslinking agent comprising N, N'-phenylene dimaleimide in combination with at least one substance from the group consisting of a higher ester of an organic acid, a metal salt of acrylic acid and a metal salt of methacrylic acid. The belt is characterized by excellent heat resistance and resistance to tooth slippage at higher temperatures under higher loads, and is useful as the toothed belt in a camshaft drive for high performance automobile engine.
