Description

Technical Field

[0001] This utility model relates to the field of synthetic leather technology, and more specifically to a scratch-resistant synthetic leather. Background Technology

[0002] Synthetic leather is a man-made material that mimics the look and feel of natural leather. This material is usually made of plastics such as polyurethane or PVC and can be designed to have a variety of colors, textures, and softness.

[0003] Synthetic leather is usually textured with anti-slip patterns or embossed textures to improve the feel and appearance. Existing leather with anti-slip textures is shown in "Application No.: CN202322015792.7, An Environmentally Friendly Breathable and Wear-Resistant Sofa Leather", which has anti-slip textures on its surface.

[0004] Meanwhile, in order to improve the wear and scratch resistance of synthetic leather surfaces, a wear-resistant coating is also required. However, due to the textured surface, the wear-resistant coating tends to flow and accumulate during application, resulting in poor uniformity. Utility Model Content

[0005] The purpose of this utility model is to provide a scratch-resistant synthetic leather surface in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a scratch-resistant synthetic leather, including a leather body, a textured layer disposed on the outside of the leather body, and a scratch-resistant layer disposed on the outside of the textured layer.

[0008] The leather body includes a base layer, a cover layer and an activation layer that are sequentially bonded and fixed together, with the outer side of the activation layer bonded and fixed to the anti-scratch layer;

[0009] The scratch-resistant layer is formed by sequentially spraying multiple layers of wear-resistant coatings on the outside of the activation layer.

[0010] In a preferred embodiment of this invention, the activation layer is a silane coupling agent layer.

[0011] As a preferred embodiment of this invention, the wear-resistant coating is an acrylic resin coating.

[0012] As a preferred embodiment of this utility model, the thickness of the anti-scratch layer is 20~30μm, and when the wear-resistant coating has two layers, the thickness of the wear-resistant coating is 10~15μm.

[0013] In a preferred embodiment of this invention, the substrate layer is a polyester fiber layer.

[0014] In a preferred embodiment of this invention, the covering layer is a polyurethane resin layer.

[0015] The beneficial effects of this utility model are as follows:

[0016] By applying a scratch-resistant layer to the outer side of the leather body with a textured surface, and by using a multi-layered abrasion-resistant coating, the coating can be thinned during the application process to reduce flow and greatly inhibit the flow of the abrasion-resistant coating sprayed on the textured surface. This design ensures improved uniformity of the scratch-resistant layer. Furthermore, the activation layer enhances the adhesion of subsequent scratch-resistant layers and results in high structural strength. Attached Figure Description

[0018] Reference numerals: Leather body - 1, Textured layer - 2, Scratch-resistant layer - 3, Base material layer - 11, Top layer - 12, Activation layer - 13. Detailed Implementation

[0019] like Figure 1 As shown, this utility model proposes: a scratch-resistant synthetic leather, including a leather body 1, a textured layer 2 disposed on the outside of the leather body 1, and a scratch-resistant layer 3 disposed on the outside of the textured layer 2; by pre-setting a textured layer 2 with anti-slip texture or pattern on the top of the leather body 1, and then setting the scratch-resistant layer 3 on the top of the textured layer 2.

[0020] The leather body 1 includes a base layer 11, a cover layer 12 and an activation layer 13 that are sequentially bonded and fixed together, with the outer side of the activation layer 13 bonded and fixed to the anti-scratch layer 3;

[0021] The substrate layer 11 is a polyester fiber layer, and the cover layer 12 is a polyurethane resin layer; the polyester fiber layer is coated with a polyurethane resin layer and then cured to form a whole.

[0022] The activation layer 13 is a silane coupling agent layer; by using a silane coupling agent layer to form a thin chemical film on the top surface of the coating layer 12, the surface hydrophilicity is increased, thereby improving the adhesion of the coating and thus improving the connection strength when the anti-scratch layer 3 is set.

[0023] The anti-scratch layer 3 is formed by sequentially spraying multiple layers of wear-resistant coating on the outside of the activation layer 13; by using multiple spraying to form the anti-scratch layer 3, a thinner wear-resistant coating is provided to greatly reduce flowability, and this setting can improve the overall uniformity (especially when applied to the surface that originally had the textured layer 2).

[0024] The wear-resistant coating is an acrylic resin coating, which has good transparency, weather resistance and wear resistance, and can provide good gloss.

[0025] The specific application of the anti-scratch layer 3 is as follows: the thickness of the anti-scratch layer 3 is 20~30μm, and when the wear-resistant coating has two layers, the thickness of the wear-resistant coating is 10~15μm (e.g., when the thickness of the anti-scratch layer 3 is 20μm, the thickness of the wear-resistant coating is 10μm); and under these data, it is preferred that the thickness of the substrate layer 11 is 100~150μm, the thickness of the topcoat layer 12 is 20~30μm, and the thickness of the activation layer 13 is 1~2μm, so as to ensure sufficient strength and durability, without being too thick and heavy to affect the overall flexibility and feel;

[0026] As shown in the figure, two layers of wear-resistant coating are sprayed in sequence. The first layer is cured before the second layer is sprayed. This is used to form the total thickness of the anti-scratch layer 3. Compared with spraying this thickness in one go, the fluidity produced after spraying is small.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
