[0002] The tpu leather is a kind of synthetic leather material with excellent performance, mainly by thermoplastic polyurethane (tpu) as base raw material, sometimes also add pigment, resin, filler and other materials to improve its performance or appearance;Its manufacturing process is to mix tpu with other additive materials to form liquid or paste mixture, then pour or spread it on the surface of plastic, metal, etc., after curing or hardening treatment, form the flexible, durable and waterproof sheet similar to the appearance and texture of natural leather.

[0003] The existing technical problem of tpu leather is that, due to tpu in the manufacturing process, a large number of pores for gas to pass through are not formed naturally, without these pores as the channel of gas, air cannot smoothly enter and exit the material, thereby affecting its ventilation performance, and because its surface morphology is relatively smooth and dense, the contact area of gas molecules with the surface of the material is relatively small, and it is difficult to form effective adsorption and penetration on the surface, which is not conducive to the exchange and circulation of gas, and also reduces its ventilation to some extent, therefore, we propose a tpu leather with ventilative waterproof structure to solve the above problems.

Detailed Implementation

[0024] 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.

[0025] Example: Figures 1-3 As shown, a TPU leather with a breathable and waterproof structure includes a leather layer 10, on the outer surface of which a plurality of breathable holes 11 are formed and evenly arranged; a middle layer 20 is also provided on the lower surface of the leather layer 10, and an inner layer 40 is provided on the lower surface of the middle layer 20. The middle layer 20 and the inner layer 40 are provided with breathable structures corresponding to the breathable holes 11, which facilitates gas exchange and improves the breathability of the TPU leather.

[0026] Among them, such as Figure 2 As shown, the leather layer 10 includes TPU resin 101 and a heat dissipation material layer. A wear-resistant structure is also fixedly provided on the outer surface of the leather layer 10. The heat dissipation material layer is graphene 102. Since the leather layer 10 is the outermost layer, and decorative patterns such as patterns are generally printed on the leather layer 10, a wear-resistant structure is provided on the leather layer 10 to protect the leather layer 10 and improve the durability of the TPU leather. The wear-resistant structure will be further described below.

[0027] Among them, such as Figure 1 As shown, the wear-resistant structure is a first reinforcing rib 60, which is evenly arranged longitudinally along the leather layer 10. Furthermore, the first reinforcing rib 60 has a wavy shape. The function of the first reinforcing rib 60 on the leather layer 10 is, firstly, to improve the wear resistance of the leather, and secondly, as... Figure 1As shown, the second reinforcing rib 30 is arranged uniformly along the transverse direction, and the first reinforcing rib 60 and the second reinforcing rib 30 are arranged alternately in the longitudinal direction and the transverse direction, so that the tensile resistance of the tpu leather is increased, and the first reinforcing rib 60 can also increase the heat dissipation surface area of the leather layer 10. Since the tpu resin 101 and the graphene 102 have good waterproof properties, the waterproof effect of the tpu leather is improved. In addition, the graphene 102 has good heat dissipation performance, and the heat conducted through the inner layer 40 of the leather can be dissipated through the outermost leather layer 10. The process of the graphene 102 and the tpu resin 101 generally adopts a mechanical processing method, that is, the two are crushed and mixed according to a proportion, and then formed. The raw materials and the process method are prior art, and thus will not be described in detail in the specification. The leather layer 10 can increase the heat dissipation, and is good for ventilation and waterproof.

[0028] As shown in the drawings, Figures 1-2 As shown, the second reinforcing rib 30 is in a strip shape, and the reinforcing ribs 30 and 60 are located between adjacent air holes 11 or adjacent air holes of the intermediate layer 20 and the inner layer 40, so that the tpu leather is ventilated conveniently.

[0029] As shown in the drawings, Figure 1 As shown, the air holes of the intermediate layer 20 are mesh holes 21, and a plurality of groups of mesh holes 21 are uniformly arranged on the outer surface of the intermediate layer 20. The inner layer 40 can also adopt other air holes, such as air holes.

[0030] As shown in the drawings, Figure 2 In order to facilitate the heat conducted by the inner layer 40 to be dissipated in time, a heat dissipation layer 50 is also arranged on the lower surface of the inner layer 40. The heat dissipation layer 50 also needs to be provided with air holes to ensure the exchange of air. The heat dissipation layer 50 can be installed on the inner layer 40 by means of glue or other fixing and waterproof means.

[0031] The above only describes preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
