The invention belongs to automobile tire technical field more particularly to a kind of carcass plies of steel wire carcass car tire.Handling poor, the resistance to load property of car tyre solved currently on the market is strong, and rolling resistance is big, is badly in need of a kind of carcass ply with higher fatigue durability and intensity to meet the technical problem of the needs of steel wire carcass car tire.It covers glue composition by cord and is made with steel cord；It includes base rubber, reinforcing agent, vulcanizing activator, anti-aging agent, promotor, insoluble sulfur, binder resin, methylene donor, cobalt salt and antiscorching agent that the cord, which covers glue composition,；The steel cord is twisted by 5 outermost cover wires around 1 twisting steel wire of internal layer volume.Tire safety intensity made of the carcass ply of steel wire carcass car tire produced by the present invention is obviously improved, low manufacture cost, and tire drag reduces, fuel consumption per hundred kilometers reduces 2%-4%, conducive to low-carbon environment-friendly, comfort is promoted, and braking distance and noise level are improved. |
