Abstract
The invention belongs to automobile tire technical field more particularly to a kind of cords of full steel structure meridian passenger vehicle tyre 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 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 8 outermost cover wires around 3 twisting steel wire of internal layer volumes.Tire safety intensity made of the cord of full steel structure meridian passenger vehicle tyre carcass 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.
Description
Technical field
The invention belongs to automobile tire technical field more particularly to a kind of full steel structure meridian passenger vehicle tyre carcasses
Cord.
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.
Handling poor, the resistance to load property of car tyre currently on the market is strong, and rolling resistance is big, is badly in need of a kind of with higher resistance to
Fatigability and all steel carcass ply of intensity meet full steel structure meridian passenger vehicle tyre demand.
Summary of the invention
The present invention provides a kind of cords of full steel structure meridian passenger vehicle tyre carcass, solve currently on the market
Handling poor, the resistance to load property of car tyre it is strong, rolling resistance is big, is badly in need of a kind of carcass with higher fatigue durability and intensity
Cord meets the technical problem of the needs of steel wire carcass car tire.
In order to achieve the above object, the present invention provides the following technical scheme that
A kind of cord of full steel structure meridian passenger vehicle tyre carcass covers glue composition by cord and steel cord makes
It forms；
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 and 0.1-0.4 parts of antiscorching agent；
The steel cord is twisted by 8 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 0.695-0.765mm；
It is 12.5mm 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 6.3mm.
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 >=880N 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 3.0-7.0g/kg, and the copper content of coating is 61.0%-66.0%；It is described
Steel cord line density be 1.95-2.26g/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-2.6mm, covers glue composition thickness
Spend tolerance+0.05mm；The calendering density of the carcass ply is 48-108 root/dm.
Compared with prior art, the invention has the following advantages:
