Description

Technical Field

[0001] This utility model relates to the field of membrane technology, and in particular to an organosilicon leather for grips. Background Technology

[0002] In the field of tennis equipment, the material of the tennis racket grip plays a crucial role in a player's hitting experience and performance. Currently, common tennis racket grip materials on the market mainly include natural leather, synthetic rubber, carbon fiber, and hybrid materials.

[0003] Natural leather grips offer a good feel and moisture absorption, providing a comfortable grip for players. However, their durability is poor; they are prone to wear and aging after prolonged use, requiring frequent maintenance and replacement, which undoubtedly increases the cost and effort for players. Synthetic rubber, while possessing excellent elasticity and anti-slip properties and good durability, lacks breathability. In hot environments, players' hands tend to sweat, causing the grip to become damp and affecting stability. Carbon fiber grips offer high strength and stiffness, are lightweight, and have good shock absorption; however, their stiffness can be difficult for players accustomed to softer grips to adapt to. Hybrid grips, while combining the advantages of multiple materials, suffer from performance instability in some products due to the immaturity of the material fusion technology in actual production.

[0004] In summary, existing tennis racket grip materials cannot simultaneously meet players' needs in terms of breathability, aesthetics, slip resistance, stain resistance, and elasticity. To address these issues, we have developed a new racket grip material that combines breathability, aesthetics, slip resistance, stain resistance, and elasticity. Utility Model Content

[0005] The present invention aims to solve the above-mentioned problems by providing an organic silicone leather for grips.

[0006] To achieve the above objectives, this utility model provides a silicone leather for a grip, comprising, from top to bottom, a silicone layer, a base fabric layer, and an elastic layer. The silicone layer has a predetermined texture and / or multiple breathable pores, and the elastic layer is fitted to the grip. Here, "and / or" includes "and" or "or".

[0007] In this invention, the surface layer of the silicone leather for the grip is made of silicone, which can improve the stain resistance, water repellency, and scratch resistance of the silicone leather for the grip. In addition, by setting a predetermined texture and / or multiple pores in the silicone layer, the breathability, aesthetics, and anti-slip properties of the silicone layer surface can be enhanced. The elastic layer can enhance the elasticity of the grip. Thus, a silicone leather for the grip that is breathable, aesthetically pleasing, anti-slip, stain-resistant, and elastic can be provided.

[0008] In the silicone leather for grips involved in this utility model, the base fabric layer can optionally be made of four-way stretch fabric. Four-way stretch fabric has good elasticity, wrinkle resistance, breathability, moisture absorption, and shaping effect, thereby improving the elasticity, wrinkle resistance, breathability, and moisture absorption of the silicone leather for grips.

[0009] In the silicone leather for grips disclosed in this invention, the elastic layer may optionally be made of sponge or foam. Sponge or foam has good elasticity, breathability, and moisture absorption, thereby improving the elasticity, breathability, and moisture absorption of the silicone leather for grips.

[0010] In the silicone leather for grips involved in this utility model, optionally, the silicone layer includes at least one of silicone rubber, silicone resin, and fluorosilicone polymer.

[0011] In the silicone leather for grips involved in this utility model, optionally, the silicone resin includes at least one of VMQ silicone resin and MQ silicone resin. In this case, MQ silicone resin has excellent heat resistance and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent isolation properties. Making MQ resin as the outermost layer can improve the heat resistance, low temperature resistance, weather resistance, water repellency, and isolation properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) has excellent heat resistance, low temperature resistance, film-forming properties (able to form a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. Making VMQ silicone resin as the outermost layer can improve the heat resistance, low temperature resistance, film-forming properties (able to form a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties of the TPU composite film. The mixture of the two can combine the above-mentioned performance advantages.

[0012] In the silicone leather for grips involved in this utility model, the base fabric layer may optionally be one of microfiber, nonwoven fabric, knitted fabric, or woven fabric.

[0013] In the silicone leather for grips involved in this utility model, optionally, the silicone layer includes a first silicone layer, a second silicone layer and a third silicone layer arranged sequentially from top to bottom, wherein the second silicone layer is made by adding a luminescent material to liquid silicone.

[0014] In the silicone leather for grips involved in this utility model, optionally, a luminescent material is also added to the first silicone layer.

[0015] In the silicone leather for grips involved in this utility model, optionally, the third silicone layer is prepared by adding a colorant to liquid silicone.

Compared to existing natural leather, synthetic rubber, and carbon fiber, this silicone leather grip offers superior properties such as breathability, aesthetics, slip resistance, stain resistance, and elasticity. The silicone leather grip can be used for tennis rackets, badminton rackets, and any other grip-friendly implements.

[0025] Reference Figure 1To achieve the above objectives, this utility model provides a silicone leather 1 for a grip. In some embodiments, the silicone leather 1 for a grip includes a silicone layer 10, a base fabric layer 20, and an elastic layer 30 arranged sequentially from top to bottom.

[0026] In this invention, the surface layer of the silicone leather 1 for the grip is made of silicone, which can improve the anti-fouling, hydrophobic, and scratch-resistant properties of the silicone leather 1 for the grip. In addition, by setting a predetermined texture and / or multiple ventilation holes in the silicone layer 10, the breathability, aesthetics, and anti-slip properties of the surface of the silicone layer 10 can be enhanced. The elastic layer 30 can enhance the elasticity of the grip. Thus, a silicone leather 1 for the grip that is breathable, aesthetically pleasing, anti-slip, anti-fouling, and elastic can be provided.

[0027] In some embodiments, the base fabric layer 20 may be made of four-way stretch fabric. Four-way stretch fabric has good elasticity, wrinkle resistance, breathability and moisture absorption, as well as shaping effect, thereby improving the elasticity, wrinkle resistance, breathability and moisture absorption of the silicone leather 1 for the grip.

[0028] In some embodiments, the elastic layer 30 may be made of sponge or foam. Sponge or foam has good elasticity, breathability and moisture absorption, thereby improving the elasticity, breathability and moisture absorption of the silicone leather 1 for the grip.

[0029] In some embodiments, the silicone layer 10 may include at least one of silicone rubber, silicone resin, and fluorosilicone polymer. Silicone resin has high and low temperature resistance, adhesion, water repellency, aging resistance, and high transparency; fluorosilicone polymer has antifouling, hydrophobic, scratch-resistant, and weather-resistant properties; and silicone rubber has good thermal stability, weather resistance, and biocompatibility. By adding the above components to the silicone layer, the silicone layer can possess the above-mentioned excellent properties.

[0030] In some embodiments, the silicone resin includes at least one of VMQ silicone resin and MQ silicone resin. In this case, MQ silicone resin has excellent heat and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent isolation properties. Using MQ resin as the outermost layer can improve the heat resistance, low temperature resistance, weather resistance, water repellency, and isolation properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) has excellent heat resistance, low temperature resistance, film-forming properties (able to form a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. Using VMQ silicone resin as the outermost layer can improve the heat resistance, low temperature resistance, film-forming properties (able to form a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties of the TPU composite film. A mixture of the two can combine the above-mentioned performance advantages.

[0031] In some embodiments, the base fabric layer 20 is one of microfiber, nonwoven fabric, knitted fabric, or woven fabric.

[0032] Reference Figure 2 In some embodiments, the silicone layer 10 may include a first silicone layer 11 and a second silicone layer 12 disposed sequentially from top to bottom. In other words, the second silicone layer 12 may be disposed between the first silicone layer 11 and the base fabric layer 20. The second silicone layer 12 may be made by adding a luminescent material to liquid silicone.

[0033] Of course, in some embodiments, the silicone layer 10 may also consist of only one silicone layer.

[0034] In some embodiments, the silicone layer 10 may further include a third silicone layer 13. The third silicone layer 13 may be disposed between the second silicone layer 12 and the base fabric layer 20. The third silicone layer 13 can enhance the abrasion resistance of the silicone layer 10.

[0035] In some embodiments, a luminescent material may also be added to the first silicone layer. This enhances the luminescent properties of the silicone leather 1 for the grip.

[0036] In some embodiments, the third silicone layer 13 is prepared by adding a colorant to liquid silicone. In other words, the third silicone layer 13 can serve as a colored silicone layer or a backing layer. In some embodiments, the color of the silicone leather colorant for the grip is adapted to the color of the luminescent material of the silicone leather for the grip. For example, when the luminescent material is phosphorescent powder, the luminescent color of the phosphorescent powder can be adapted to the color of the third silicone layer 13. For example, when the luminescent color of the phosphorescent powder is blue, the color of the third silicone layer 13 can be made blue, thereby enabling the phosphorescent powder to emit a stronger blue light; of course, the color of the third silicone layer 13 can be made in other colors, thereby enabling the phosphorescent powder to emit a more brilliant mixed light.

[0037] In some embodiments, the luminescent material of the silicone leather for the grip is one of the following: fluorescent powder, phosphorescent powder, reflective powder, thermochromic powder, pearlescent powder, photochromic powder, and phosphorescent powder.

[0038] In some embodiments, the silicone leather 1 for the grip may further include a tactile layer, which may be disposed on the side of the silicone layer 10 away from the base fabric layer 20. The tactile layer may be formed by coating the surface of the silicone layer 10 with a tactile oil. The tactile layer can enhance the user's tactile experience.

[0039] In some embodiments, when the tactile layer is the outermost layer, a predetermined texture and / or multiple vents can be provided on the tactile layer.

[0040] In some embodiments, at least one of an antifungal agent and an antibacterial agent may be added to the silicone layer 10.

[0043] In some embodiments, the silicone layer 10 may include at least one of a silicone rubber layer, a silicone resin layer, or a mixed layer made of silicone rubber and silicone resin.

[0044] In some embodiments, the silicone resin may include at least one of VMQ silicone resin, MQ silicone resin, and fluorosilicone resin. In this case, MQ silicone resin possesses excellent heat and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent barrier properties. Using MQ resin as the outermost layer can enhance the heat resistance, low temperature resistance, weather resistance, water repellency, and barrier properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) possesses excellent heat resistance, low temperature resistance, film-forming properties (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and barrier properties.

It also exhibits superior high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency. Using fluorosilicone resin as the outermost layer can enhance the high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency of the TPU composite film. A mixture of two or three of these properties can combine the advantages of both.

[0045] In some embodiments, the silicone rubber may include at least one of dimethyl silicone rubber, methyl vinyl silicone rubber, phenyl silicone rubber, or fluorosilicone rubber.

[0046] In some embodiments, the liquid silicone can be liquid silicone rubber, liquid silicone resin, or a mixture of liquid silicone rubber and liquid silicone resin.

[0047] In some embodiments, the proportion of luminescent material in the silicone layer 10 can be 5%-50%. Preferably, the proportion of luminescent material in the silicone layer 10 can be 10%-20%. This allows for reduced manufacturing costs while ensuring luminescence effects.

[0048] In some embodiments, in addition to colorants, dispersants and additives may also be added to the liquid silica gel. Therefore, the addition of dispersants and additives ensures that the colorants are evenly distributed in the liquid silica gel.
