The invention belongs to automobile tire technical field more particularly to a kind of cords of full-steel radial ply tyres for passenger cars carcass.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 full-steel radial ply tyres for passenger cars.Glue composition is covered by cord to be made with steel cord；It includes base rubber, reinforcing agent, vulcanizing activator, anti-aging agent, promotor, insoluble sulfur, binder resin, methylene donor, cobalt salt, antiscorching agent that cord, which covers glue composition,；The steel cord is twisted by 9 outermost cover wires around 3 twisting steel wire of internal layer volumes.Tire safety intensity made of the carcass ply of full-steel radial ply tyres for passenger cars produced by the present invention is obviously improved, the low manufacture cost of manufactured tire, and tire drag reduces, fuel consumption per hundred kilometers reduces 2%-4%, conducive to low-carbon environment-friendly, comfort is promoted, and braking distance is improved. |
