Description

Technical Field

[0001] This utility model relates to the field of reflective technology, specifically a tire reflective cloth. Background Technology

[0002] Reflective strips and labels on tires are made of reflective fabric suitable for tires, serving as a warning to pedestrians and drivers, significantly improving vehicle visibility, reducing the visibility of parked vehicles in poor lighting conditions in rural areas at night, and minimizing the risk of collisions. Reflective strips and labels also enhance the tire's appearance during the day. However, there is currently no suitable reflective strip or label on the market for electric vehicle and motor vehicle tires. Existing reflective strips and labels lack elasticity, are attached to semi-finished tires, and detach under pressure during vulcanization, failing to bond properly with the tire rubber. Existing elastic fabric reflective strips tend to have black spots on the outer layer due to tire rubber being squeezed out from the elastic fabric during vulcanization. Furthermore, the elastic fabric does not bond firmly to the tire rubber and is prone to detachment.

[0003] The utility model patent CN221678436U describes a tire reflective structure that lacks elasticity. If a 50mm wide reflective structure is applied to the sidewall of a semi-finished tire, the outer ring of the reflective structure on the finished tire needs to be 50mm x 2 x 3.14 = 314mm longer than the inner ring. This patented reflective structure cannot stretch and will roll up or detach during vulcanization. Furthermore, during vulcanization, the tire sidewall rubber is subjected to intense internal pressure, causing it to penetrate the reflective structure and gradually cover the reflective layer, severely impacting appearance and reflectivity. Utility Model Content

[0004] The purpose of this invention is to provide a tire reflective fabric to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tire reflective fabric; comprising a reflective layer, an elastic fabric layer, an adhesive layer, and a rubber layer.

[0007] The elastic fabric layer, adhesive layer, and rubber layer are sequentially bonded from top to bottom. The reflective layer is located on the top surface of the elastic fabric layer and is fixedly bonded. The bottom surface of the elastic fabric layer has a knitted fabric layer. The elastic fabric layer and the knitted fabric layer are integrally woven together. The adhesive layer is excessively filled with adhesive material, which penetrates into the gaps of the knitted fabric layer. The rubber layer has a smooth surface and is tightly bonded to the adhesive layer.

[0008] As a preferred embodiment of this utility model: the overall thickness of the elastic fabric layer and the knitted fabric layer is 0.2mm to 0.5mm; the thickness of the rubber layer is 0.1mm to 0.5mm, and the rubber layer is a semi-vulcanized rubber sheet; the overall thickness of the elastic fabric layer and the rubber layer after the adhesive is bonded together is 0.3mm to 1.0mm.

[0009] As a further preferred embodiment of this utility model: the reflective layer is composed of adhesive, reflective powder, luminescent powder, and rare earth phosphorescent powder.

[0010] As a further preferred embodiment of this utility model: the top surface of the rubber layer and the bottom surface of the elastic fabric layer are provided with multiple arc grooves, and the arc grooves are the same length as the corresponding rubber layer and elastic fabric layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The reflective fabric in this patent solution is designed to be woven into an integral shape by the elastic fabric layer and the knitted fabric layer, which can effectively reduce the thickness of the rubber layer, greatly improve the extensibility and bending performance of the product, and can automatically adapt to the vulcanization bonding and fixing installation of tires of different sizes. This avoids the rolling or falling off phenomenon that occurs in conventional products of this type during the vulcanization process. Furthermore, the design of the knitted fabric layer allows the rubber material to penetrate, which also effectively ensures the stability of the product itself. The elastic fabric layer also facilitates the color processing of the reflective layer. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Example 1:

[0018] Please see Figure 1 In this embodiment of the utility model, a tire reflective cloth includes a reflective layer 2, an elastic cloth layer 1, an adhesive layer 3, and a rubber layer 5.

[0019] The elastic fabric layer 1, adhesive layer 3, and rubber layer 5 are sequentially bonded from top to bottom. The reflective layer 2 is located on the top surface of the elastic fabric layer 1 and is fixedly bonded. The bottom surface of the elastic fabric layer 1 has a knitted fabric layer 4. The elastic fabric layer 1 and the knitted fabric layer 4 are integrally formed by weaving. The adhesive layer 3 is excessively filled with adhesive material, which penetrates into the gaps of the knitted fabric layer 4. The surface of the rubber layer 5 is smooth and is tightly bonded to the adhesive layer 3.

[0020] By injecting excessive amounts of rubber, the rubber paste layer 3 formed after the rubber solidifies forms a tight bond with the elastic fabric layer 1. Due to the smooth surface of the rubber layer 5, the contact area with the rubber is large enough to maintain a stable bond.

[0021] Furthermore, the overall thickness of the elastic fabric layer 1 and the knitted fabric layer 4 is 0.2mm to 0.5mm; the thickness of the rubber layer 5 is 0.1mm to 0.5mm, and the rubber layer 5 is a semi-vulcanized rubber sheet; after the adhesive is bonded to the elastic fabric layer 1 and the rubber layer 5, the overall thickness is 0.3mm to 1.0mm.

[0022] Specifically, the adhesive is made by soaking and stirring a viscous adhesive in a solvent such as No. 120 gasoline with 1 part adhesive and 3 parts viscous adhesive. The adhesive is then soaked into the gaps of the elastic knitted fabric, and the adhesive of the adhesive is tightly bonded to the fibers of the elastic knitted fabric. After drying, the elastic knitted fabric and the adhesive of the adhesive are tightly bonded together. Then, the elastic fabric with adhesive is laminated with the rubber layer 5 to form a complete reflective fabric.

[0023] Before use, the reflective fabric is vulcanized by heating equipment until the film reaches a semi-vulcanized state. The semi-vulcanized film has a certain toughness and elasticity. When the tire is vulcanized, the tire rubber and the semi-vulcanized film continue to vulcanize together and are firmly bonded together. The semi-vulcanized film also prevents the high-pressure tire rubber during vulcanization from penetrating the film into the elastic knitted fabric.

[0024] The reflective layer 2 is composed of adhesive, reflective powder, luminescent powder, and rare earth phosphorescent powder, mixed in different proportions and of different types, presenting colors such as white, silver-gray, green, red, blue, and yellow.

[0025] In use, reflective tire fabric is cut into strips of various widths to become reflective strips, which are then attached to various tires. Printing on reflective tire fabric of various colors creates colored reflective tire labels.

[0026] Example 2:

[0027] Based on Example 1, the top surface of the rubber layer 5 and the bottom surface of the elastic fabric layer 1 are provided with multiple arc grooves 6, and the arc grooves 6 have the same length as the corresponding rubber layer 5 and elastic fabric layer 1.

[0028] After the elastic fabric layer 1 and the knitted fabric layer 4 are woven and formed, and the rubber layer 5 is cut to the required width, the rubber layer 5 and the elastic fabric layer 1 are wound up and unwound along their length. Multiple sets of parallel rollers are set between the winding and unwinding mechanisms. During the winding and unwinding process, the rollers roll and squeeze to form an arc groove 6. Through the formation of the arc groove 6, the amount of adhesive injected into the adhesive layer 3 is increased during the adhesive injection process, and the bonding area of ​​the adhesive to the contact surfaces of the upper and lower layers is effectively increased, which more effectively ensures the stability of the reflective fabric forming. Furthermore, during the adhesive injection process, the arc groove 6 distinguishes it from a single plane. When air enters the bonding surface and there are voids, it can effectively form a guiding channel, which helps the air to be discharged and greatly reduces the product defect rate.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
