AI Technical Summary
Traditional leather materials tend to absorb heat under sun exposure, resulting in an increase in temperature, affecting their comfort and service life in high temperature environments. The prior art has limited effect on improving reflectivity through dyeing or coating, and is usually accompanied by a decrease in breathability and flexibility.
A heat-reflective leather is designed, which consists of a base cloth layer, a foam layer, an antistatic layer, an air permeable layer and a dermis layer. The dermis layer is raised upward at equal intervals to form a supporting bump. The reflective film is arranged on the surface of the dermis layer between the supporting bumps. Breathable holes are opened on the outer wall of the supporting bumps, and the top is coated with an alumina thermal insulation coating.
Through the configuration of the reflective film and thermal insulation coating, the light and high temperature irradiation on the leather surface are effectively reflected, protecting the leather layer, improving the high temperature resistance of the leather, while maintaining the softness and breathability of the leather.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0015] As Figure 1 and Figure 2 shown, a heat-reflective leather from bottom to top is successively a base fabric layer 1, a foaming layer 2, an antistatic layer 3, a breathable layer 4 and a genuine leather layer 5. The base fabric layer 1, the foaming layer 2, the antistatic layer 3, the breathable layer 4 and the genuine leather layer 5 are compounded into one body by a hot pressing process. A plurality of support bumps are formed on the genuine leather layer 5 protruding upward at equal intervals. A reflective film 7 is arranged on the surface of the genuine leather layer 5 between adjacent support bumps. The reflective film 7 is used to reflect the light irradiated on the surface. A plurality of ventilation holes 8 are opened on the outer side wall of the support bump, and the ventilation holes 8 are communicated with the breathable layer 4.
[0016] In this embodiment, the top surface of the support bump is coated with a heat insulation coating 9, and the heat insulation coating 9 is an alumina coating.
[0017] In this embodiment, the reflective film 7 is an aluminum foil film, and the reflective film 7 is bonded to the surface of the genuine leather layer 5 through a water-based adhesive.
[0018] In this embodiment, the antistatic layer 3 is woven from silver fibers, and the silver fibers have excellent antistatic and bactericidal properties.
[0019] In this embodiment, the breathable layer 4 is woven from ramie fibers.
[0020] The working principle of this embodiment is as follows:
[0021] The leather is pressed with support protrusions 6 on the true leather layer 5, so that when the user uses it, they are in contact with the support protrusions 6, and the non-protruding parts do not directly contact the user. The stuffiness can be avoided by reducing the contact area. Moreover, the concave-convex bending structure also increases the softness of the true leather layer 5. At the same time, the ventilation holes 8 opened on the side walls of the support protrusions 6 can play the role of ventilation and moisture discharge, and the air permeability will not be affected by the presence of the heat insulation coating 9;
[0022] By coating an aluminum oxide coating on the surface of the support protrusions 6, the nano-aluminum oxide particles in the aluminum oxide coating have a high solar reflectivity and a low absorption rate, which can effectively reflect the visible light and infrared parts in the sunlight, thereby reducing the direct light hitting the leather surface. The reflective film 7 in the groove between adjacent support protrusions 6 can effectively reflect the light hitting the surface of the reflective film 7, and at the same time effectively avoid the deformation of the groove part of the true leather layer 5 caused by long-term irradiation. And since the user does not directly contact the reflective film 7, the presence of the reflective film 7 will not affect the comfort during use.
[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
