Abstract
The present invention relates to steel cord technical field, particularly a kind of open type steel cord with 1+5+10 structures, including central core, intermediate layer and outer layer, the central core is a diameter of d1 silk thread, in the intermediate layer a diameter of d2 five silk threads with lay pitch p1 around central core, in the outer layer a diameter of d3 ten silk threads with lay pitch p2 around intermediate layer；Gap between the adjacent silk thread of the same layer is not less than 25 μm.After said structure, this invention ensures that the appropriate clearance between silk thread, eliminates closed gap, it is the cord of structure opening, it is ensured that the infiltration of rubber, is the steel cord of excellent performance so as to improve the fatigue life of cord and improve bonding force.
Description
Technical field
The present invention relates to steel cord technical field, particularly a kind of open type steel cord with 1+5+10 structures.
Background technology
Steel cord is to develop product the most wide in rubber framework material, be also in metallic article production difficulty it is maximum
Product.Definition of the international synthetic fibers standardization office in a standard to steel cord be：" it is made up of two or more than two steel wires
, or combination by stock and stock or the structure that is formed by the combination of stock and silk." traditional bias tire be with fiber (such as
Polyester cord, nylon cord) as framework material, and new radial then selects steel cord as framework material,
All-steel radial tyre and semi-steel radial tire can be divided into by its structure, the former belt and carcass all uses steel cord
As framework material, the belt steel cord of the latter, carcass fiber are used as framework material.Car, light truck are typically adopted
With semi-steel radial tire, heavy type truck, engineering machine vehicle use all-steel radial tyre.
Chinese invention patent CN 103485216A disclose a kind of compound steel cord with 4+10+16 structures, including in
Central layer, intermediate layer and outer layer, described central core with a diameter of d1 of lay pitch p1 helical assemblies four silk threads by being constituted, in
A diameter of d2 ten silk threads are wound in a spiral in around the central core with lay pitch p2 in interbed, a diameter of d3 in the outer layer
Ten six roots of sensation silk threads be wound in a spiral in lay pitch p3 around the intermediate layer.There are many closed seams inside the cord of this patent
Gap, rubber can not be penetrated into these gaps completely, and these gaps are full of air and aqueous vapor in tire, and cord can be produced
Corrosiveness, reduces cord fatigue life.
The content of the invention
The technical problem to be solved in the invention is to provide the steel cord that a kind of rubber permeates completely.
In order to solve the above technical problems, a kind of open type steel cord with 1+5+10 structures of the present invention, including center
Layer, intermediate layer and outer layer, the central core are a diameter of d1 silk thread, a diameter of d2 five silks in the intermediate layer
Line with lay pitch p1 around central core, in the outer layer a diameter of d3 ten silk threads with lay pitch p2 wound on intermediate layer
Around；Gap between the adjacent silk thread of the same layer is not less than 25 μm.
Further, the central core wire diameter d1 is intermediate layer filaments diameter d2 75%-100%, the outer layer
Wire diameter d3 is intermediate layer filaments diameter d2 100%-120%.
Further, the central core and intermediate layer form core strand, and the core strand is twist-on-twist with outer layer.
Further, the core strand lay pitch p1 is outer layer lay pitch p2 30%-70%.
After said structure, this invention ensures that the appropriate clearance between silk thread, eliminates closed gap, it is that structure is opened
The cord put, it is ensured that the infiltration of rubber, is excellent performance so as to improve the fatigue life of cord and improve bonding force
Steel cord.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation of the open type steel cord with 1+5+10 structures of the present invention.
In figure：Layer centered on 1,2 be intermediate layer, and 3 be outer layer
Embodiment
As shown in figure 1, a kind of open type steel cord with 1+5+10 structures of the present invention, including central core 1, intermediate layer
2 and outer layer 3, the central core 1 is a diameter of d1 silk thread, in the intermediate layer 2 a diameter of d2 five silk threads with
Lay pitch p1 is around central core, and a diameter of d3 ten silk threads are all wound on intermediate layer with lay pitch p2 in the outer layer 3
Enclose；Gap between the adjacent silk thread of the same layer is not less than 25 μm.
Further, the central core wire diameter d1 is intermediate layer filaments diameter d2 75%-100%, the outer layer
Wire diameter d3 is intermediate layer filaments diameter d2 100%-120%.
Further, the central core and intermediate layer form core strand, and the core strand is twist-on-twist (SS or ZZ) with outer layer.
Further, the core strand lay pitch p1 is outer layer lay pitch p2 30%-70%.
Embodiment one：
1st, the semi-finished product brass wire diameter 1.40mm of production 0.20；
2nd, the semi-finished product brass wire diameter 1.60mm of production 0.22；
3rd, the semi-finished product brass wire diameter 1.80mm of production 0.24；
4th, production core strand 0.20+5x0.22；
5th, production cord 0.20+5x0.22+10x0.24 7.5/16SS.
Gap L 1 in present embodiment in intermediate layer 2 between adjacent silk thread is in 26.9 μm, outer layer 3 between adjacent silk thread
Gap L 2 be 31.9 μm.
Certainly, silk thread of the invention can also use steel wire or other applicable materials, and such conversion all falls within this hair
Within bright protection domain.
The present invention by the optimum organization of core wire and two outside layers steel wire diameter and using 1+5 core strands and outer layer+
10 layer of two step twist-on-twist shaping, it is ensured that the suitable gap between every layer and every steel wire, it is ensured that the complete infiltration of rubber, due to
100% strike-through performance, fatigue life, bonding force life-span of the specification in tire is better than the tight type commonly used at present and other
The layer structure cord of the classical 3+9+15+1 outer wrapping wire of band.The present invention is applied to each strength grade curtain of NT, HT, ST, UT, MT
Line.
Although the foregoing describing the embodiment of the present invention, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle and essence of the present invention,
Protection scope of the present invention is only limited by the claims that follow.
