Description

Technical Field

[0001] This utility model relates to the field of car cover fabric technology, specifically a multi-layer composite scratch-resistant car cover fabric. Background Technology

[0002] A car wrap is a protective film applied to the exterior of a car, primarily used to protect the paint from environmental damage while enhancing the car's appearance and resale value. Based on function and aesthetics, car wraps are generally categorized into invisible car wraps (transparent wraps) and colored car wraps (tinted films).

[0003] Currently, most car covers consist of a film layer and an adhesive layer. The film layer adheres to the vehicle surface through the adhesive layer, providing both protection and decoration. However, the outer surface of the film layer is prone to leaving stains or water droplets, requiring frequent cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer composite scratch-resistant car cover fabric to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite scratch-resistant car cover fabric, comprising:

[0019] 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.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1:

[0022] Please see Figure 1-2 This utility model provides a technical solution: a multi-layer composite scratch-resistant car cover fabric, comprising: a base layer 1, a surface coating 2, and an adhesive layer 4;

[0023] The outer surface of the base layer 1 is provided with a surface coating 2, and the adhesive layer 4 is provided on the side of the base layer 1 opposite to the surface coating 2. The surface coating 2 is a nano-polyurethane coating. A release film layer 5 is provided on the side of the adhesive layer 4 opposite to the base layer 1.

[0024] Analysis of the above content: The release film layer 5 is a conventional design. Based on the release film layer 5, the adhesive layer 4 is covered and protected. In use, the release film layer 5 is directly peeled off, and the base layer 1 and the surface coating 2 are then attached to the outer surface of the car through the adhesive layer 4.

[0025] Surface coating 2 is a material in which nano-sized silica particles are added to polyurethane (this is existing technology, and its proportion is existing technology, which will not be elaborated here). The dense structure of the nano-coating material can block ultraviolet rays, acid rain, bird droppings and other corrosive substances. Some products add fluorides to improve hydrophobicity (such as lotus leaf effect).

[0026] Example 2:

[0027] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: an anti-ultraviolet layer 3 is provided between the base layer 1 and the surface coating 2.

[0028] Analysis of the above content: UV protection layer 3 is a PU film with added UV absorbers (such as benzotriazole compounds), which can absorb UV radiation (280~400nm band) and also adopts existing technology, which will not be elaborated here.

[0029] Example 3:

[0030] Please see Figure 1-2 This utility model provides a technical solution based on Embodiment 1: the base layer 1 is a thermoplastic polyurethane layer with a thickness of 30-50 micrometers. The adhesive layer 4 is an acrylic pressure-sensitive adhesive layer.

[0031] Example 4:

[0032] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the surface of the adhesive layer 4 is uniformly provided with grooves 6, and the lower surface of the base layer 1 is provided with protrusions that match the grooves 6.

[0033] Analysis of the above: The dimensions of the groove 6 and the protrusions are set according to the actual thickness of the base layer 1 and the adhesive layer 4. The diameter of the protrusions is set to 5-20 micrometers. The cooperation between the groove 6 and the protrusions increases the contact area and provides a certain degree of anti-slip and anti-detachment effect.
