Description

Colorful leather, preparation method and application Technical Field The invention relates to the application field of leather and composite materials, in particular to a colorful leather, a preparation method and application. Background Currently, the leather materials on the market are all monochromatic and solid, so when the leather materials are applied to the shells or surface materials of electronic products, furniture products, wall surface decorative materials and the like, the color and pattern are difficult to print on the outer surfaces of the products. For example, existing leather, including artificial leather sofas, are generally single-color and cannot be added with patterns or colors on the surface. The existing mobile phone shells made of PC, PU and other materials are easy to fade or wear in the conventional mode, have insufficient durability and are not durable enough, and meanwhile, the surfaces of the products are likely to be polluted easily and difficult to clean based on the material difference of the outer shells or the surface materials of the products, so that the attractiveness and the service life are affected. In view of the above, the prior art fails to provide a durable and flexible solution for customizing colors or patterns to the product housing or surface materials. Disclosure of Invention In order to overcome the defects in the prior art, a colorful leather, a preparation method and application are provided. The colorful leather comprises a bottom layer, wherein the bottom layer is used for being attached to the surface of a preset product, the bottom layer is made of transparent materials, characters or patterns with preset colors are printed on one side of the bottom layer facing the preset product, or a material layer is arranged on one side of the bottom layer facing the preset product, and the material layer comprises the characters or patterns with the preset colors. A preparation method of colorful leather is used for preparing colorful leather and comprises the following steps: obtaining a transparent bottom substrate, wherein the size of the bottom substrate is matched with the size of the surface to be attached of the preset product; Printing characters or patterns with preset colors on the surface of a bottom layer directly by adopting a screen printing, gravure printing or digital jet printing process, or attaching a layer of prepared material layer on the surface of the bottom layer by adopting a hot pressing, gluing or laminating process, wherein the material layer is formed by cutting a color printing film or a transparent/semitransparent film with ink patterns; Obtaining a transparent plastic sheet which is the same as or compatible with the bottom foundation as a surface layer material; and aligning and overlapping the surface layer material and the bottom substrate, and firmly bonding the two layers of transparent materials into a whole through hot pressing bonding or cold pressing bonding. An article based on a multi-colored skin, the surface of which is adhered with the multi-colored skin as described above. According to the colorful leather, the preparation method and the application, the transparent PET, PC, PU, TPU or TPE and other materials are utilized, characters and patterns with any color are manufactured on the back surface of the colorful leather in a colored drawing, silk screen printing and gold stamping mode, and meanwhile one side of the printed characters or patterns is attached to a preset product, namely, the materials adopted by the bottom layer can be played at will in a reverse printing and forward looking mode, so that the colorful leather is made into the leather with the five colors. More preferably, the composite sheet is a single sheet formed by compositing a surface layer and a bottom layer in a mode such as microfiber, wherein the surface layer is used as a protective layer, and the composite sheet has the characteristics of environmental protection, pollution resistance, scratch resistance and high temperature resistance. In use, the transparent planar material is used for electronic products such as mobile phone back plates, mobile phone shells, charging devices and the like in a mode of in-mold injection molding, pasting and the like, household appliances such as refrigerators, air conditioners and the like, furniture such as sofas, wardrobes and the like, daily necessities such as handbags and the like, and even house decoration materials such as wall decoration and the like, and the printed characters or patterns are not easy to change color, abrade and scratch due to the fact that the printed characters or patterns are printed on one side facing to a preset product. Compared with the prior art, the technical scheme has the advantages of environmental protection, pollution prevention, high temperature resistance and scratch resistance, is comfortable in touch feeling, has rich and durable color, characters and patterns
