Technical Field

[0001] The utility model relates to the technology of leather field, in particular to a graphene ultra-fiber leather. Background Art

[0002] Animal leather is the main material currently used by humans to make fabrics. Due to its good strength, shoes or related leather goods made from it are strong, durable and beautiful in appearance. At the same time, because animal leather itself has natural pores, animal leather has good natural air permeability and moisture absorption, and is comfortable to wear.

[0003] At present, leather fabrics are widely used in the production of various products, especially for the decoration of various vehicle interiors and daily wear in people's lives. As is well known, vehicles, especially cars, are mostly made of leather fabrics for the front and rear seats and the inner surface of the body; in addition, leather is also widely used in daily wear, such as leather coats, leather shoes, leather gloves, etc., which have won people's favor. However, due to the shortage and high cost of animal leather resources, the corresponding leather products are expensive and do not meet the needs of the public. Therefore, relatively low-cost synthetic leather has emerged. However, the existing leather has poor thermal conductivity, durability, toughness and other properties, which cannot meet the user's use needs and affect the service life of the product.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A graphene ultra-fine leather comprises a bass layer and a graphene polyurethane resin layer, wherein the bass layer is attached to the upper surface of the graphene polyurethane resin layer, and the graphene polyurethane resin layer is composed of graphene powder, polyurethane resin, DMF and organic color powder.

[0008] As a preferred solution, the bass layer is ultra-fine fiber bass.

[0011] As a preferred solution, the bass layer is bonded to the upper surface of the graphene polyurethane resin layer through an adhesive layer.

[0012] As a preferred solution, an antibacterial layer is bonded to the upper surface of the bass layer.

[0013] As a preferred embodiment, the antibacterial layer is a textile layer; the textile layer includes bamboo charcoal fiber weft threads and cotton and linen fiber warp threads woven into a sheet, or the textile layer includes bamboo charcoal fiber weft threads and silver antibacterial nylon fiber warp threads woven into a sheet.

[0014] As a preferred solution, a breathable layer is arranged on the upper surface of the antibacterial layer, and a wear-resistant base fabric layer is arranged on the upper surface of the breathable layer.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it is mainly through the provision of a graphene polyurethane resin layer, and the graphene polyurethane resin layer is composed of graphene powder, polyurethane resin, DMF, and organic color powder. In this way, the excellent properties of graphene can be converted into a coating and applied to leather, so that the leather has the corresponding graphene properties, thereby making it have excellent thermal conductivity, durability, toughness and other properties, thereby improving the service life of the product and meeting the user's usage needs.

[0025] Please refer to Figures 1 to 3 As shown, it shows the specific structure of two embodiments of the utility model; wherein, Figure 1 The specific structure of the first embodiment is shown. Figures 2 to 3 The specific structure of the second embodiment is shown.

[0026] like Figure 1 As shown, in Example 1, a graphene ultra-fine leather includes a bass layer 10 and a graphene polyurethane resin layer 20, wherein the bass layer 10 is attached to the upper surface of the graphene polyurethane resin layer 20, and the graphene polyurethane resin layer 20 is composed of graphene powder, polyurethane resin, DMF, and organic color powder. Preferably, the bass layer 10 is an ultra-fine fiber bass, and the ultra-fine fiber bass is composed of a substrate and a hand feeling agent, and the substrate is preferably a base resin.

[0027] The general production process of the graphene ultra-fiber leather is as follows:

[0028] Step 1: rinse the substrate with water, add a hand-feeling agent, dry and set aside to obtain a microfiber bass; here, the hand-feeling agent can make the hand feel closer to the leather feel;

[0029] Step 2, adding graphene powder into DMF to fully decompose to obtain graphene stock solution, wherein the ratio of graphene powder to DMF is 1:1;

[0030] Step 3, adding the organic color powder and the graphene stock solution obtained in step 2 to the polyurethane resin, and stirring thoroughly until the viscosity is about 3000 rpm;

[0031] Step 4, coating the mixture obtained in step 3 on a release paper and drying the mixture at a temperature of 130° C. for 3 minutes to form a graphene polyurethane resin layer 20 on the surface of the release paper;
