Problems solved by technology

The presence of moisture leads to accelerated corrosion compared to use in a dry atmosphere, resulting in the phenomenon of "corrosion fatigue", a phenomenon that leads to a gradual degradation of the mechanical properties of the cords and can affect these cords under the most severe driving conditions The life of the tire, thereby reducing the service life of the tire

Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] see figure 1 As shown, the present invention has a three-layer steel cord with a structure of 4+10+16, which is twisted from thirty wires, and the cross-section of the wires is circular; it includes a central layer 1, an intermediate layer 2 and an outer layer 3 , the central layer 1 is formed by weaving and twisting four silk threads with a twist direction S twist, a twist distance of 5.08 mm, and a diameter of 0.175 mm. The cross-sections of the four silk threads in the central layer 1 are diamond-shaped structures; In 2, ten silk threads with a diameter of 0.175 mm are spirally wound around the central layer 1 in a twist direction S twist and a lay distance of 10.26 mm; in the outer layer 3, sixteen silk threads with a diameter of 0.175 mm are twisted The steel cord is spirally wound around the middle layer 2 ...

Abstract

The invention discloses a three-layer steel cord with a structure of 4+10+16, including a central layer, a middle layer and an outer layer. The central layer is composed of four wires with a diameter of d1 helically assembled at a lay length p1 In the middle layer, ten wires with a diameter of d2 are helically wound around the central layer with a lay length p2, and in the outer layer sixteen wires with a diameter d3 are helically wound with a lay length p3. around the middle layer. The steel cord has complete structure, stable performance, high strength, strong load-bearing capacity, good corrosion resistance and high safety performance.

Description

technical field [0001] The invention relates to steel cords used in pneumatic tires, in particular to dense steel cords used in large truck tires. Background technique [0002] In addition to carcass strength, the selection of carcass cords for all-steel radial truck tires also takes into account the repeated flexing deformation of the sidewall. Therefore, the carcass cord should have high breaking force, fatigue resistance and wear resistance. At present, steel cords with a structure of 3+9+15×0.175+0.15 are generally used in the carcass of all-steel radial truck tires. capacity, which puts forward higher requirements for the production of steel cords for carcass in pneumatic tires. China Intellectual Property Office has disclosed CN201080029415.1 a three-layer (C1+C2+C3 ), which is rubberized in situ and comprises a first or central layer (C1), a second layer (C2) and a third layer (C3), said first or central layer (C1) Consists of two wires of diameter d1 helically ass...
