Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction tires, in particular to an anti-sticking sealant and a self-repairing noise reduction tire. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims. They can support the vehicle body, cushion external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and cushioning performance.

[0003] For example, the Chinese patent number CN217022096U is an anti-sticking sealant and a self-repairing noise-reducing tire. In this utility model, the sealant structure is convex or concave to establish a reference position for attaching the sound-absorbing sponge, so that the sound-absorbing sponge is attached to the center line of the sealant without deviating from the center line, and the attachment of the sound-absorbing sponge is more efficient and convenient. However, in this utility model, the sound-absorbing sponge is installed on the tread of the tire liner, resulting in subsequent air tightness and other mechanisms that will seal the sound-absorbing sponge, forming a sealing structure for the tire body, thereby inflating it, making it difficult for the sound-absorbing sponge to play a noise reduction effect in this environment, which is not conducive to the user's use. Therefore, an anti-sticking sealant and a self-repairing noise-reducing tire are proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, an anti-sticking sealant and a self-repairing noise reduction tire include a carcass 1, a tread layer 2 is installed on the top of the carcass 1, sidewall layers 3 are installed on the left and right sides of the carcass 1, a cap layer 4 is installed between the outer surface of the carcass 1 and the inner wall of the tread layer 2, a belt layer 5 is installed inside the carcass 1, two buffer layers 6 are installed inside the carcass 1, an anti-leakage protection layer 7 is connected to the inner wall of the carcass 1, an air cord layer 8 is installed on the outer surface of the anti-leakage protection layer 7, an airtight layer 9 is installed inside the cord layer 8, triangular sealants 10 are arranged on the left and right sides of the cord layer 8, and tire bead wires 11 are connected to the left and right sides of the cord layer 8.

[0023] exist Figure 1 and Figure 2 In the embodiment, the fine tread grooves and wide tread grooves provided on the tread layer 2 come into contact with the ground when the tire is running, thereby generating grip and providing friction, thereby improving the tire's anti-skid performance. At the same time, the fine tread grooves are used to reduce the air accumulation noise between the tire tread blocks, and the wide tread grooves and fine tread grooves are staggered to form an irregular and variable pitch design, thereby dispersing sound waves to different frequency ranges, thereby reducing noise.

[0024] exist Figure 2 In the invention, since the polymer composite material of the leakproof protective layer 7 is in a soft solid gel state, the noise generated by the tire and the ground can be reduced, and the vibration between the tire and the ground when the tire is running at high speed can be alleviated. When a sharp object is inserted, the soft solid gel-like polymer composite material will tightly wrap the sharp object and seal the puncture in time to achieve a leakproof effect. When the sharp object is pulled out, the soft solid gel-like polymer composite material at the puncture will automatically close, and the puncture will be bonded together by virtue of its viscosity, so that the tire can still run normally at high speed to achieve a self-repairing effect.

[0025] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0026] When implementing, follow these steps:

[0027] 1) First, two bead wires 11 are distributed and placed in the semi-open annular grooves wound on both sides of the carcass layer 8;

[0028] 2) Then, apply triangular sealant 10 on the notch of the semi-open annular groove and the outer surface of the cord layer 8;

[0029] 3) Finally, the cord layer 8 is brought into contact with the interior of the carcass 1 so that the triangular sealant 10 is stuck between the anti-leakage protection layer 7 and the cord layer 8 to prevent the tire bead wire 11 from being offset during installation, thereby ensuring the stability of the assembly.

[0030] In summary, the anti-sticking sealant and self-repairing noise-reducing tire utilize the inclined inclination angle of the sidewall layer 3 to reduce the thickness of the wide surface of the tire and reduce the noise generated by friction. The staggered wide and fine pattern grooves on the outer surface of the tread layer 2 can disperse sound waves to different frequency ranges, thereby reducing noise. There is no need for additional noise reduction operations through noise reduction components such as sound-absorbing sponges, thereby reducing the cost of tire production.

[0031] Moreover, the triangular sealant 10 can seal and limit the tire bead wire in the semi-open annular groove of the cord layer 8, thereby achieving an anti-sticking and biased sealing effect. At the same time, the soft solid colloidal polymer composite material of the leak-proof protective layer 7 has a noise reduction function, thereby reducing the noise generated by the tire and the ground, alleviating the vibration between the tire and the ground when driving at high speed, making driving more comfortable, and solving the problem in the comparative document that the sound-absorbing sponge is difficult to fully exert the sound absorption and noise reduction effect, which is not conducive to user use.
