[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0012] Please see Figure 1-3The present invention provides the following technical solution: an aging-resistant modified TPU artificial leather, comprising a lower artificial leather layer 1, and an anti-tensile layer 3, an upper artificial leather layer 4, an aging-resistant component 5, and a plush decorative surface layer 2 arranged sequentially from the lower artificial leather layer 1 upwards. The aging-resistant component 5 includes an anti-ultraviolet coating 51. An anti-ultraviolet coating 51 is provided at one end of the upper artificial leather layer 4 near the plush decorative surface layer 2. An ultra-thin polyvinylidene fluoride film 52 is provided between the anti-ultraviolet coating 51 and the plush decorative surface layer 2. A composite antibacterial coating 54 is provided at the upper end of the plush decorative surface layer 2. A polyurethane elastic film 53 is provided at the upper end of the composite antibacterial coating 54. The plush decorative surface layer 2 and the ultra-thin polyvinylidene fluoride film 52 are connected by a connecting component 6.

[0013] Specifically, the connecting component 6 includes a hook and loop fastener 61, a hook and loop fastener 61 fixed to the outer side of the lower end of the plush decorative surface layer 2, a hook and loop hook fastener 63 fixed to the upper end of the ultra-thin polyvinylidene fluoride film 52 at a position corresponding to the hook and loop fastener 61, an upper anti-slip pad 62 fixed to the lower end of the plush decorative surface layer 2, and a lower anti-slip pad 64 fixed to the upper end of the ultra-thin polyvinylidene fluoride film 52 at a position corresponding to the upper anti-slip pad 62.

[0014] By adopting the above technical solution, the connecting component 6 is set to facilitate the disassembly, replacement or cleaning of the plush decorative surface layer 2, so as to avoid the need to replace the entire artificial leather when the plush decorative surface layer 2 has local wear, stains or aging. The connecting component 6 facilitates the disassembly, replacement or cleaning of the plush decorative surface layer 2.

[0015] Specifically, the composite antibacterial coating 54 is made of bamboo charcoal fiber, and the UV-resistant coating 51 is made of fluorinated resin.

[0016] By adopting the above technical solutions, bamboo charcoal fiber itself has a rich microporous structure, which can capture microorganisms such as bacteria and mold through physical adsorption. At the same time, the natural bamboo quinone substances it contains can destroy the cell membrane of microorganisms, achieving a dual antibacterial effect of "adsorption + sterilization". The fluorinated resin coating has extremely low surface energy and excellent hydrophobic and oleophobic properties. Water droplets and oil stains can quickly roll off the coating surface, forming a "self-cleaning" effect and reducing the adhesion of dust and stains.

[0017] Specifically, the hook and loop fastener 61 is sewn to the plush decorative surface layer 2, and the hook and loop fastener 63 is bonded to the ultra-thin polyvinylidene fluoride film 52 with high-strength adhesive. Both the upper anti-slip pad 62 and the lower anti-slip pad 64 are made of rubber.

[0018] By adopting the above technical solution, the sewing and high-strength adhesive bonding make the hook and loop fastener 61 and the plush decorative surface layer 2, as well as the hook and loop fastener 63 and the ultra-thin polyvinylidene fluoride film 52, more secure. In addition, the upper anti-slip pad 62 and the lower anti-slip pad 64 are both rubber structures, which provides better anti-slip effect.

[0019] The working principle and usage process of this utility model: When using the aging-resistant modified TPU artificial leather, an anti-ultraviolet coating 51 and an ultra-thin polyvinylidene fluoride film 52 are set on the upper side of the artificial leather layer 4. The anti-ultraviolet coating 51 has excellent anti-ultraviolet penetration and can directly block most ultraviolet rays from contacting the inner structure. The ultra-thin polyvinylidene fluoride film 52 can not only directly reflect ultraviolet rays, but also form a dense protective film to reduce the erosion of the substrate by ultraviolet rays and rainwater. A polyurethane elastic film 53 and a composite antibacterial coating 54 are set on the upper end of the plush decorative surface layer 2. The polyurethane elastic film 53 has high light transmittance and does not affect the visual texture and touch of the plush. At the same time, it can directly withstand external friction, avoid sharp objects from scratching the plush, and has excellent aging resistance. It is not easy to yellow after long-term use. The composite antibacterial coating 54 forms a continuous antibacterial zone on the surface, avoiding the growth of microorganisms caused by daily contact such as hand contact, sweat adhesion, or humid environment.

[0020] When installing the plush decorative surface layer 2, the Velcro surface 61 at the bottom of the plush decorative surface layer 2 is bonded to the Velcro hook surface 63 at the top of the ultra-thin polyvinylidene fluoride film 52 to achieve the effect of fixing the plush decorative surface layer 2. At the same time, the upper anti-slip pad 62 at the bottom of the plush decorative surface layer 2 contacts the lower anti-slip pad 64 at the top of the ultra-thin polyvinylidene fluoride film 52 to prevent wrinkles from forming in the plush decorative surface layer 2. The connecting component 6 is set to facilitate the disassembly, replacement or cleaning of the plush decorative surface layer 2, so as to avoid the need to replace the entire artificial leather when the plush decorative surface layer 2 has local wear, stains or aging. The connecting component 6 is set to facilitate the disassembly, replacement or cleaning of the plush decorative surface layer 2.
