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.
Description
Technical field
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.
Background technique
Automobile industry is worldwide grown rapidly, and automobile tire is the important component of vehicle, quality and
The quality of performance directly influences vehicle performance.The body piles that meridian tyre body curtain cloth layer is formed by covering glue cord fabric,
It is the stress frame layer of tire.Radial divides according to carcass ply, and carcass is the referred to as All-steel tire of steel wire,
It is generally used for business load-carrying tire；Carcass is that fiber is half steel tire, is generally used for riding tire.
Car tyre operability is poor currently on the market, and resistance to load property is poor, and rolling resistance is big, is badly in need of a kind of with higher resistance to tired
The carcass ply of labor and intensity meets the needs of full-steel radial ply tyres for passenger cars.
Summary of the invention
The present invention provides a kind of cord of full-steel radial ply tyres for passenger cars carcass, solve currently on the market riding
Handling poor, the resistance to load property of tire is strong, and rolling resistance is big, and it is next to be badly in need of a kind of carcass ply with higher fatigue durability and intensity
Meets the technical problem of the needs of full-steel radial ply tyres for passenger cars.
In order to achieve the above object, the present invention provides the following technical scheme that
A kind of cord of full-steel radial ply tyres for passenger cars carcass, it is characterised in that: the carcass ply covers glue by cord
Composition is made with steel cord；
It includes parts by weight that the cord, which covers glue composition: 100 parts of base rubber, 45-60 parts of reinforcing agent, vulcanization are lived
8-10 parts of agent of property, 1-3 parts of anti-aging agent, 1-1.5 parts of promotor, 4-6 parts of insoluble sulfur, 1-2 parts of binder resin, methylene are given
Give 4-6 parts of body, 0.4-1.2 parts of cobalt salt, 0.1-0.4 parts of antiscorching agent；
The steel cord is twisted by 9 outermost cover wires around 3 twisting steel wire of internal layer volumes.
Further, 70-100 parts of natural rubber, 0-30 parts of butadiene-styrene rubber in the base rubber；Described is natural
Rubber is SMR10/20 or STR10/20；The butadiene-styrene rubber is the SBR1502 of low temperature cream polymerizing technology production.
Further, the dosage of the butadiene-styrene rubber is 10-30 parts by weight；
The dosage of the reinforcing agent is 48-54 parts by weight, and the reinforcing agent is Audit For Process technique N326 carbon black, institute
The nitrogen adsorption surface area for the Audit For Process technique N326 carbon black stated is 72-84 ㎡/g, and dibutyl terephthalate absorbs after compression
Value is 62-74ml/g.
Further, the vulcanizing activator is the zinc oxide produced using zinc ingot metal as raw material indirect method, and specific surface area is
4-8㎡/g；
The dosage of the anti-aging agent is 2-3 parts by weight, and the anti-aging agent is p phenylenediamine type antioxidant 6PPD；
The promotor is sulfenamide type accelerators DZ；
The insoluble sulfur is HD OT-20.
Further, the dosage of the binder resin is 1.2-1.8 parts, and the binder resin is resorcinol first
Urea formaldehyde；
The methylene donor is hexamethylolmelamine pregnancy ether, in hexamethylolmelamine pregnancy ether
HMMM content 65%, white carbon black content 35%；
The cobalt salt is the cobalt decanoate that effective content is 20-21%；
The antiscorching agent is N- cyclohexylthiophthalimide.
Further, all steel wire diameters are identical, are 0.693-0.763mm；
It is 10.0mm that the cover wire of the steel cord, which compiles the lay pitch twisted,；The steel wire of internal layer of the steel cord, which is compiled, to be twisted
The lay pitch be 5.00mm.
Further, the cover wire and steel wire of internal layer of the steel cord are twisted using S in the same direction to volume, one-pass molding.
Further, Fracture Force >=755N of the steel cord；The steel cord covers the viscous of glue composition with described
With joint efforts >=700N；
The plating weight of copper of the steel cord is 3.5-6.3g/kg, and the copper content of coating is 61.0%-66.0%；It is described
Steel cord line density be 2.20-2.44g/m.
Further, the steel cord is suitable for NT, HT, ST, UT or MT grade steel wire.
Further, carcass ply calendering covers glue composition with a thickness of 1.2mm-2.5mm, covers glue composition thickness
Spend tolerance+0.05mm；The calendering density of the carcass ply is 50-110 root/dm.
Compared with prior art, the invention has the following advantages:
1, tire safety intensity made of the carcass ply of full-steel radial ply tyres for passenger cars produced by the present invention significantly mentions
It rises, the risk damaged after tire collides under steam can be further reduced.
2, compared to tire made of more other fibrous materials, the carcass of full-steel radial ply tyres for passenger cars produced by the present invention
The low manufacture cost of tire made of cord, tire drag reduce, and fuel consumption per hundred kilometers reduces 2%-4%, are conducive to low-carbon ring
It protects.
