The foam layer filling the middle of the dense layer improves the rebound and enhances the comfort when wearing the shoe.

Description

Technical Field

[0001] This utility model relates to the field of rubber technology for footwear, and more specifically to a wear-resistant and tear-resistant rubber for footwear materials. Background Technology

[0002] Rubber soles are a high-performance and widely used shoe sole material. Their elasticity, abrasion resistance, slip resistance, and corrosion resistance make them widely used in various types of shoes. However, existing rubber soles are typically manufactured using a one-piece molding design, which leads to the following problems: Firstly, their abrasion resistance is limited. Most soles wear down quickly due to constant contact with the ground, limiting the shoe's lifespan. Therefore, a sole structure with good abrasion resistance is needed. Secondly, existing rubber soles generally have poor rebound ability. Their material composition is relatively simple, usually consisting of one or two types of rubber. This limited tensile strength makes them unsuitable for frequent movement and jumping. Finally, existing rubber soles have poor tear resistance, making them prone to breakage after prolonged wear, which also significantly affects the sole's lifespan. Therefore, rubber soles have certain limitations and require structural improvements. To address these issues, the inventors propose a wear-resistant and tear-resistant rubber for shoe materials. This material features a double-layer, dual-density rubber structure, comprising a dense layer and a foamed layer. The high-density dense layer enhances the wear resistance of the rubber sole, while the low-density foamed layer improves its resilience, making it more suitable for shoe sole manufacturing and effectively extending its service life.

[0003] To improve the flexural and tear resistance of rubber shoe soles, while also enhancing their abrasion resistance and increasing wearing comfort, Chinese Patent (Authorization Announcement No.: CN221576967U) discloses a flexurally resistant, non-slip shoe sole. This invention includes a sole mechanism comprising a sole body with anti-slip treads on its top. The sole body includes an abrasion-resistant layer, a reinforcing layer, and a comfort layer. The abrasion-resistant layer is located on top of the reinforcing layer, and the reinforcing layer is located on top of the comfort layer. The reinforcing layer includes an anti-flexural layer, a puncture-resistant layer, and a strength layer. This invention ensures the abrasion resistance and flexural resistance of the sole mechanism by incorporating an abrasion-resistant layer, a puncture-resistant layer, and a strength layer to form the reinforcing layer, thereby increasing its flexural and tear resistance.

[0004] The solution still has some shortcomings in its application. Since rubber soles are widely used, including as work shoes, outdoor shoes, and mountaineering shoes, in addition to being wear-resistant, they also need to have good rebound properties so that the shoes can be elastic when worn. Otherwise, they are easy to be uncomfortable to wear and not conducive to long-term walking and running. Therefore, it is necessary to improve the structure of rubber for shoes so that it has good wear resistance, tear resistance and rebound effect, making it safe, comfortable to wear and long-lasting. Utility Model Content

[0005] This utility model discloses a wear-resistant and tear-resistant rubber for footwear materials, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A wear-resistant and tear-resistant rubber for footwear includes a rubber body. The rubber body comprises, from top to bottom, a PU inner layer 1, a tear-resistant layer 2, and a wear-resistant layer 3. The PU inner layer 1, the tear-resistant layer 2, and the wear-resistant layer 3 are bonded together by a high-temperature composite method. The tear-resistant layer 2 includes an outer dense layer 4 and an inner foam layer 5. The dense layer 4 has a filling groove 6 in the middle. A puncture-resistant steel sheet 7 is embedded at the bottom of the filling groove 6. The foam layer 5 is embedded in the filling groove 6 to form a midsole of the shoe sole. The midsole of the shoe sole is bonded to the PU inner layer 1.

[0008] Furthermore, the depth of the filling groove 6 is 3cm, and the edge thickness is 3-8mm.

[0009] Furthermore, the dense layer 4 has a Shore hardness of 70-80 degrees, a density of 1.15-1.35 g / cm³, and a density of 0.65-0.85 g / cm³.

[0010] Furthermore, the dense layer 4 and the foamed layer 5 are manufactured by compression molding.

[0011] Furthermore, the bottom of the wear-resistant layer 3 is provided with anti-slip texture 8, and wear-resistant sheets 9 are bonded to the toe and heel of the shoe.

[0012] Furthermore, the puncture-resistant steel sheet 7 has a thickness of 0.5 cm and is bonded to the wear-resistant layer 3.

[0014] 1. This utility model uses a layered rubber body, including a PU inner bottom layer, a tear-resistant layer, and an abrasion-resistant layer. The abrasion-resistant layer is located at the bottom and has an anti-slip pattern. Abrasion-resistant sheets are bonded to the toe and heel of the shoe. Through this design, the rubber used in the shoe material has good abrasion resistance, can be worn for a long time, minimizes wear and tear, and effectively extends the service life of the sole.

[0015] 2. This utility model features a dense layer on the outside of the tear-resistant layer. The dense layer has a Shore hardness of 70-80 degrees and a density of 1.15-1.35 g / cm³. At the same time, a puncture-resistant steel plate is provided at the bottom of the dense layer. This design ensures that the four sides and bottom of the rubber shoe material have sufficient hardness, forming a protective layer to prevent wear, puncture, and tearing. It also has good hydrolysis resistance and acid and alkali resistance, allowing it to be worn for a long time without deformation, thus extending its service life. It is very practical.

[0016] 3. This utility model features a filling groove in the middle of a dense layer, filled with a foam layer. The foam layer has a density of 0.65-0.85 g / cm³, a relatively soft texture, and aligns perfectly with the sole of the foot, improving the rubber's resilience. As a shoe material, this results in better comfort, reduces foot pain, and prevents fatigue. Combined with a PU inner layer at the top, it effectively enhances the shoe material's softness and elasticity, making it even more suitable for wear. This utility model boasts a novel structure and ingenious design, exhibiting excellent tear resistance and abrasion resistance, as well as good resilience, making it suitable for use as a shoe material and sole.
