Description

Technical Field

[0001] This utility model relates to the field of car covers, and in particular to a high heat insulation and UV protection car cover. Background Technology

[0002] As a vehicle protective product, car covers primarily function to protect the paint from external environmental factors, such as paint aging and fading caused by sun exposure, and the effects of high temperatures on the vehicle's interior environment. Ultraviolet (UV) radiation from sunlight is the main culprit causing photo-oxidative degradation, accelerated aging, and fading of the paint and interior polymer materials. Infrared radiation, carrying a large amount of heat energy, is the main cause of a sharp increase in temperature on the vehicle's surface and inside. Currently, car covers on the market typically achieve UV protection and heat insulation by using a single functional layer or adding functional additives to the substrate. For example, adding UV absorbers to the substrate to absorb some UV rays, or coating with an infrared reflective coating to reflect some infrared rays. However, these traditional solutions have limitations such as poor functional synergy and insufficient protective efficiency. Therefore, there is an urgent need to develop a high-heat-insulating and UV-resistant car cover that can synergistically block UV and infrared rays, possessing high heat insulation and UV protection performance, and extending its service life. Utility Model Content

[0003] In order to overcome the shortcomings of existing car covers, which typically use a single functional layer or add functional additives to the base material, resulting in poor functional synergy and insufficient protective efficiency, this utility model aims to provide a high-heat-insulating and UV-resistant car cover that can synergistically block ultraviolet and infrared rays, has high heat insulation and UV resistance performance, and improves service life.

[0004] This utility model is achieved by the following specific technical means:

[0005] A high-heat-insulating and UV-resistant car cover includes a substrate layer, a functional layer, and a protective layer stacked sequentially. The functional layer is composed of multiple heat-insulating layers and multiple UV-resistant layers stacked alternately. The heat-insulating layer is a metal sputtering layer or a metal oxide nanoparticle layer, used to reflect or absorb infrared rays. The UV-resistant layer is a UV absorber coating, used to absorb ultraviolet rays. The car cover also includes an adhesive layer disposed on the side of the substrate layer away from the functional layer, and the adhesive layer contains a UV absorber to supplement the protection against ultraviolet rays on the back side of the substrate layer.

[0006] Furthermore, the ultraviolet absorber of the anti-ultraviolet layer is an organic benzotriazole compound or inorganic cerium dioxide nanoparticles.

[0007] Furthermore, the substrate layer is a biaxially oriented polyester film.

[0008] Furthermore, the protective layer is a wear-resistant and scratch-resistant coating, and the material of the wear-resistant and scratch-resistant coating is silicon dioxide or polyurethane.

[0009] Furthermore, the ultraviolet absorber dispersed within the adhesive layer is an organic benzotriazole compound or inorganic cerium dioxide nanoparticles.

[0010] Furthermore, the total number of heat insulation layers and the total number of UV-resistant layers in the functional layer are 2-10.

[0011] Furthermore, when the heat insulation layer is a metal oxide nanoparticle layer, the metal oxide nanoparticles are selected from at least one of indium tin oxide, antimony tin oxide, aluminum oxide, and zinc oxide.

[0012] Furthermore, when the heat insulation layer is a metal sputtering layer, the metal is selected from at least one of aluminum (Al), silver (Ag), and copper (Cu).

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves the effect of synergistically blocking ultraviolet and infrared rays, possessing high heat insulation and UV resistance properties, and improving service life. Attached Figure Description

[0015] Figure 1 This is a cross-sectional structural diagram of the present invention.

[0016] The labels in the attached diagram are: 1-substrate layer, 2-functional layer, 3-protective layer, 4-adhesive layer, 21-heat insulation layer, 22-UV resistant layer. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: Example

[0018] A type of car cover with high heat insulation and UV protection, such as Figure 1 As shown, the car cover includes a substrate layer 1, a functional layer 2, and a protective layer 3 stacked sequentially. The functional layer 2 is composed of multiple heat-insulating layers 21 and multiple UV-resistant layers 22 stacked alternately. The heat-insulating layer 21 is a metal sputtering layer or a metal oxide nanoparticle layer, used to reflect or absorb infrared rays. The UV-resistant layer 22 is a UV absorber coating, used to absorb ultraviolet rays. The car cover also includes an adhesive layer 4, located on the side of the substrate layer 1 away from the functional layer 2, and the adhesive layer 4 contains a UV absorber to supplement the UV protection on the back side of the substrate layer 1.

[0019] The UV absorber of the UV-resistant layer 22 is an organic benzotriazole compound or an inorganic cerium dioxide nanoparticle.

[0020] The substrate layer 1 is a biaxially oriented polyester film;

[0021] The protective layer 3 is a wear-resistant and scratch-resistant coating, and the material of the wear-resistant and scratch-resistant coating is silicon dioxide or polyurethane;

[0022] The ultraviolet absorber dispersed in the adhesive layer 4 is an organic benzotriazole compound or inorganic cerium dioxide nanoparticles.

[0023] When the heat insulation layer 21 is a metal oxide nanoparticle layer, the metal oxide nanoparticles are selected from at least one of indium tin oxide, antimony tin oxide, aluminum oxide, and zinc oxide;

[0024] When the heat insulation layer 21 is a metal sputtering layer, the metal is selected from at least one of aluminum (Al), silver (Ag), and copper (Cu).

[0025] Working principle:

[0026] The outermost protective layer 3 of this car cover is made of wear-resistant and scratch-resistant materials such as silicon dioxide or polyurethane, mainly resisting external physical damage. Its inner functional layer 2 is composed of multiple heat-insulating layers 21 and multiple UV-resistant layers 22 precisely stacked alternately. The UV-resistant layer 22 contains a high concentration of UV absorbers, such as organic benzotriazole compounds or inorganic cerium dioxide nanoparticles, which can effectively capture and convert high-energy UV photons into harmless heat energy, preventing their penetration. The heat-insulating layer 21 uses a metal sputtering layer or a metal oxide nanoparticle layer. The metal sputtering layer can reflect incident infrared rays like a mirror, directly reflecting them back to the external environment. The metal oxide nanoparticle layer can absorb and convert specific wavelengths of infrared rays. To reduce heat transfer, the alternating stacked structure greatly extends the propagation path of light within the functional layer 2 and the opportunity for it to contact the functional materials. This allows ultraviolet rays to be absorbed and converted layer by layer, while infrared rays are continuously reflected or absorbed and weakened, significantly improving the overall synergistic blocking efficiency of ultraviolet and infrared rays. The substrate layer 1 on the inner side of the functional layer 2 uses a high-strength, weather-resistant biaxially oriented polyester film to provide support for the entire car cover structure. The innermost adhesive layer 4 also contains ultraviolet absorbers, forming a second line of defense. This ensures that even if a trace amount of ultraviolet rays penetrates the outer structure, they will be captured and converted before reaching the paint surface, thus achieving excellent heat insulation and ultraviolet resistance performance.

[0027] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
