Description

Technical Field

[0001] The present application relates to the field of tires, and in particular to a glass fiber rod, a rubber material containing the glass fiber rod, and a tire. Background Art

[0002] Glass fiber rod is a corrosion-resistant, tensile-resistant, lightweight and low-cost material, which is often used as a reinforcing material for rubber products to improve the structural strength of rubber products. For example, refer to the utility model patent with announcement number CN 2027059648 U and announcement date 2018.03.02. The application document discloses a new type of puncture-proof and leak-proof tire, which increases the strength of the tire by setting a titanium-chromium alloy belt layer and a glass fiber belt layer, making the tire less likely to be punctured by sharp objects, ensuring the long-term stable use of the tire.

[0003] Regarding the above-mentioned related technologies, the shear strength of glass fiber is relatively low. Since the force on the tire is relatively complex, the glass fiber is prone to breakage under the action of lateral force, which in turn affects the durability of the tire. Summary of the invention

[0004] In order to improve the structural strength of glass fiber and thus ensure the durability of the tire, the present application provides a glass fiber rod.

[0005] The glass fiber rod provided in this application adopts the following technical solution:

[0006] A glass fiber rod comprises a fiber rod body, the diameter of which is 1.0-1.5 mm. The fiber rod body comprises a metal wire core and a glass fiber layer, the metal wire core is arranged in the glass fiber layer, and the diameter of which is 0.1-0.2 mm.

[0007] By adopting the above technical solution, the shear strength of the metal wire core is relatively high, and the combination with the glass fiber layer increases the shear strength and tensile strength of the glass fiber rod, thereby improving the structural strength of the glass fiber and reducing the occurrence of shearing or pulling of the glass fiber belt, thereby ensuring the durability of the tire.

[0008] Optionally, the material of the metal wire core is steel.

[0009] By adopting the above technical solution, the steel cost is low and the strength is high, which is convenient for large-scale application.

[0010] Optionally, the metal wire core is coaxially arranged with the glass fiber layer.

[0011] By adopting the above technical solution, the coaxially arranged metal wire core and glass fiber layer can ensure that the internal force of the glass fiber rod is uniform, thereby reducing the occurrence of local damage to the glass fiber rod.

[0012] Optionally, a plurality of the fiber rod bodies are provided, and the plurality of the fiber rod bodies are wound around each other.

[0013] By adopting the above technical solution, a plurality of fiber rods wound around each other jointly resist external forces, which is beneficial to ensuring both tensile strength and shear strength.

[0014] The present application also provides a rubber material, which adopts the following technical solution:

[0015] A rubber material comprises the above-mentioned fiberglass rod.

[0016] By adopting the above technical solution, the glass fiber rod increases the puncture resistance of the rubber material, which is beneficial to ensure the durability of the tire.

[0017] Optionally, a rubber layer is further included, and the fiberglass rod is arranged in the rubber layer.

[0018] By adopting the above technical solution, the rubber layer protects the fiberglass rod. On the one hand, it makes the fiberglass rod less likely to be damaged by friction. On the other hand, it also makes it easier for the rubber layer to evenly transfer force to the fiberglass rod, thereby ensuring the service life of the rubber layer and thus ensuring the durability of the tire.

[0019] The present application also provides a tire, which adopts the following technical solution:

[0020] A tire comprises the above-mentioned fiberglass rod.

[0021] Optionally, it also includes a rubber carcass and a rubber crown, wherein the rubber crown is connected to the rubber carcass, and the glass fiber rods are woven to form a first belt layer, and the first belt layer is arranged in the rubber carcass and close to the rubber crown.

[0022] By adopting the above technical solution, the first belt layer increases the structural strength of the rubber carcass near the rubber crown, making the rubber carcass less likely to be punctured and damaged.

[0023] Optionally, the first belt layer is covered with a second belt layer, and the width of the second belt layer is smaller than that of the first belt layer, and the second belt layer is woven from glass fiber rods.

[0024] By adopting the above technical solution, the second belt layer further increases the structural strength of the rubber carcass near the rubber crown, making the rubber carcass less likely to be punctured and damaged.

[0025] Optionally, it further comprises a rubber carcass, the glass fiber rods are woven to form a third belt layer, and the third belt layer is arranged on the sidewall of the rubber carcass.

[0026] By adopting the above technical solution, the third belt layer increases the structural strength of the rubber carcass sidewall, making the rubber carcass sidewall with a smaller thickness less likely to be punctured and damaged.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The metal wire core has high shear strength, and the combination with the glass fiber layer increases the shear strength and tensile strength of the glass fiber rod, thereby improving the structural strength of the glass fiber and reducing the occurrence of shearing or breaking of the glass fiber belt, thereby ensuring the durability of the tire.
