Description

Technical Field

[0001] The utility model relates to the technical field of butyl inner tubes, in particular to an anti-cracking thermoplastic butyl inner tube. Background Art

[0002] Butyl rubber is one of the four major synthetic rubbers in the world. It is a rubber product made by low-temperature cationic polymerization of isobutylene and a small amount of isoprene under the action of a catalyst.

[0003] With the development of the automotive industry, more stringent requirements have been placed on tires, such as safety, environmental protection, low rolling resistance, ride comfort, and good maneuverability. Currently, most existing vehicle inner tubes generally use butyl inner tubes. According to the utility model patent No. CN 221541118 U, a puncture-resistant butyl inner tube is disclosed. This utility model relates to the technical field of butyl inner tubes and includes an inner tube body, a protective pad disposed on the outer side of the inner tube body, a puncture-proof netting disposed within the inner tube body, and the puncture-proof netting provides protection against sharp objects puncturing the inner tube. Thin sharp objects have lower strength, allowing them to be guided through the puncture-proof netting, bending the ends of the sharp objects to avoid puncturing the inner tube body, thereby achieving puncture-proofing. However, sharp objects can cause minor damage to the surface of the butyl inner tube, thereby altering the outer structure of the inner tube. Over extended use, the air within the inner tube expands due to heat, causing cracks in the inner tube, leading to rupture. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a crack-resistant thermoplastic butyl inner tube, which solves the problem that the traditional butyl inner tube expands due to heat during use after being damaged, causing cracks in the inner tube.

[0006] Preferably, the reinforcing rib is an I-shaped structure, and the reinforcing rib is fixedly connected to the tensile mesh layer when passing through the tensile mesh layer, and can limit the tensile mesh layer.

[0007] Preferably, the reinforcing ribs are made of metal wires, and the tensile mesh layer is a fiber mesh woven from high-strength glass fibers.

[0008] Preferably, a high-strength elastic layer is provided between the first inner base layer and the tensile mesh layer, and both side surfaces of the high-strength elastic layer are fixedly connected to the tensile mesh layer and the first inner base layer.

[0009] Preferably, the thickness of the high-strength elastic layer is greater than that of the tensile mesh layer, a second inner base layer is provided on the inner side of the first inner base layer, and the outer side of the second inner base layer is connected to the anti-slip component.

[0010] Preferably, the anti-slip component includes an anti-slip layer, and the anti-slip layer is fixedly connected to the outer surface of the second inner base layer, one side surface of the anti-slip layer is fixedly connected with an anti-slip rubber pad, and one side surface of the base is fixedly connected with an anti-slip rubber pad, and the outer surface of the anti-slip rubber pad is provided with a frosted surface.

[0011] The utility model provides a crack-resistant thermoplastic butyl inner tube. Compared with the prior art, it has the following advantages:

[0012] The tensile mesh layer arranged on the outside of the first inner base layer can prevent the outer protective layer in the inner tube body from being lost, and can limit the inner tube body to prevent the gas inside the inner tube body from expanding due to heat and cracking during the driving of the vehicle. The reinforcing ribs arranged between the outer protective layer and the first inner base layer can reinforce the tensile mesh layer to prevent the tensile mesh layer from being pulled and damaged during the crack resistance process, and improve the firmness of the tensile mesh layer, while improving the crack resistance of the inner tube body.
