Description

Technical Field

[0001] This utility model relates to the field of membrane technology, and in particular to a light-emitting car cover. Background Technology

[0002] A car cover, also known as an automotive protective film, is a product used to protect the paint of a car from damage caused by the external environment. With the booming development of the automotive industry and the rise of personalized consumption trends, people's demand for the protection and personalization of their car's exterior is increasing. A car cover not only protects the paint from scratches, UV rays, bird droppings, and other natural and man-made damage, but also provides a personalized decorative effect.

[0003] In existing technologies, the production of car covers typically involves adding dyes and functional powders to the inside or one side of a TPU film to achieve different visual effects. Some high-end car covers add an extra layer of aluminum film to enhance reflectivity and impart a metallic sheen. However, this approach has limitations, as the conductivity of the aluminum film may block car radar signals, affecting the user experience. Furthermore, Chinese patent application CN108410386A discloses a metallic-gloss weather-resistant car cover invisible protective film, which achieves a metallic sheen through a varnish coating and a substrate layer, but the metallic sheen effect is not strong.

[0004] Besides the limitations in visual appeal, the aforementioned car cover products used for automotive interiors have poor toughness and abrasion resistance, and are not conducive to maintenance. In addition, the anti-fouling, hydrophobic, scratch-resistant, UV-resistant, and weather-resistant properties of car cover products still need to be improved. Utility Model Content

[0009] In the luminescent car cover of this utility model, optionally, a supporting layer is provided between the luminescent layer and the TPU layer. This allows the supporting layer to enhance the color of the luminescent layer; for example, if the luminescent layer is to emit yellow light, the supporting layer can be set to be yellow.

[0010] In the luminescent car cover of this utility model, optionally, the backing layer is made by adding a colorant to liquid organosilicon.

[0017] In the luminous car cover of this utility model, optionally, the functional layer is transparent.

[0018] In the luminescent car cover of this utility model, optionally, an adhesive is applied between the TPU layer and the functional layer.

[0019] In the luminous car cover of this utility model, the adhesive can optionally be glue, instant glue, UV glue, OCA glue or TPU treatment agent CL-25T.

[0020] In the luminescent car cover of this utility model, optionally, the organosilicon includes at least one of silicone resin and fluorosilicone polymer.

[0021] In the luminous car cover of this utility model, optionally, the silicone resin is VMQ silicone resin, MQ silicone resin, or a mixture of VMQ silicone resin and MQ silicone resin.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this 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 this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] This invention provides a luminous car cover. Compared with existing luminous car covers, this luminous car cover has advantages such as good toughness and wear resistance, as well as being stain-resistant, hydrophobic, scratch-resistant, UV-resistant, and weather-resistant. The luminous car cover can be attached to the target object for use.

[0030] This luminescent car cover can be applied to car interiors, furniture and sofa upholstery, wall stickers, etc. Preferably, this luminescent car cover can be used as a car cover. The luminescent car cover emits light, thereby enhancing the vehicle's appearance and serving as a prominent vehicle identifier in dark environments.

[0031] Reference Figure 1 To achieve the above objectives, this utility model provides a light-emitting car cover 1. The light-emitting car cover 1 may include a functional layer 40, a light-emitting layer 30, a TPU layer (Thermoplastic Polyurethane) 20, and an adhesive layer 10 stacked sequentially.

[0032] In some embodiments, the functional layer 40 may be made of silicone.

[0033] In some embodiments, organosilicon may include at least one of silicone resin and fluorosilicone polymer.

[0034] In some embodiments, the functional layer 40 may be at least one of a silicone rubber layer, a silicone resin layer, or a hybrid layer made of silicone rubber and silicone resin.

[0035] In some embodiments, the light-emitting layer 30 may be made by adding a light-emitting material to liquid organosilicon.

[0036] In some embodiments, the liquid silicone may be liquid silicone rubber, liquid silicone resin, or a mixture of liquid silicone rubber and liquid silicone resin.

[0037] In this invention, the functional layer 40, as the outermost layer, enhances the anti-fouling, hydrophobic, scratch-resistant, UV-resistant, and weather-resistant properties of the luminous car cover 1. The light emitted by the luminous layer 30 can pass through the functional layer 40 and be emitted into the environment, thereby enhancing the vehicle's appearance and serving as a display of the car's logo. The TPU layer 20, as the inner layer, improves the tensile strength, elasticity, toughness, and aging resistance of the luminous car cover 1, and is less prone to oxidation and yellowing. Furthermore, the luminous car cover 1 of this invention uses only environmentally friendly materials, exhibiting excellent environmental performance.

[0038] In some embodiments, the silicone rubber may include at least one of dimethyl silicone rubber, methyl vinyl silicone rubber, phenyl silicone rubber, or fluorosilicone rubber.

[0039] In some embodiments, the silicone resin may include at least one of VMQ silicone resin, MQ silicone resin, and fluorosilicone resin. In this case, MQ silicone resin possesses excellent heat and low temperature resistance, good weather resistance, good water repellency, good adhesion, and excellent barrier properties. Using MQ resin as the outermost layer can enhance the heat resistance, low temperature resistance, weather resistance, water repellency, and barrier properties of the TPU composite film. VMQ silicone resin (vinyl MQ silicone resin) possesses excellent heat resistance, low temperature resistance, film-forming properties (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and barrier properties. Using VMQ silicone resin as the outermost layer can enhance the heat resistance, low temperature resistance, weather resistance, water repellency, and barrier properties of the TPU composite film. Fluorosilicone resin possesses excellent properties such as temperature resistance, film-forming ability (capable of forming a uniform film layer), water repellency, aging resistance and UV radiation resistance, high transparency and low volatility, and isolation properties. It also exhibits superior high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency. Using fluorosilicone resin as the outermost layer can enhance the high-temperature resistance, corrosion resistance, insulation properties, water repellency and non-adhesion properties, weather resistance, stain resistance, insulation, high hardness, radiation protection, and high transparency of the TPU composite film. A mixture of two or three of these properties can combine the advantages of both.

[0040] In some embodiments, a luminescent material may be added to the functional layer 40. In this case, by also adding a luminescent material to the functional layer 40, the luminescent effect of the luminescent car wrap can be further enhanced.

[0041] In some embodiments, a backing layer may be provided between the light-emitting layer 30 and the TPU layer 20. This allows the backing layer to enhance the color of the light-emitting layer; for example, if the light-emitting layer 30 is intended to emit yellow light, the backing layer can be set to a yellow color.

[0042] In some embodiments, the support layer is prepared by adding a colorant to liquid silicone. Therefore, the appropriate colorant can be added to the liquid silicone according to the desired color of light emitted by the light-emitting layer 30. In some embodiments, the liquid silicone can be liquid silicone rubber, liquid silicone resin, or a mixture of liquid silicone rubber and liquid silicone resin.

[0043] In some embodiments, the thickness of the TPU layer 20 can be from 10 micrometers to 300 micrometers. Preferably, the thickness of the TPU layer 20 can be 50 micrometers or 100 micrometers.

[0044] In some embodiments, the thickness of the light-emitting layer 30 can be from 10 micrometers to 400 micrometers.

[0045] In some embodiments, the thickness of the functional layer 40 can be from 50 micrometers to 1000 micrometers.

[0046] In some embodiments, the thickness of the release layer 50 can be from 10 micrometers to 100 micrometers. Preferably, the thickness of the release layer 50 can be 50 micrometers.

[0047] In some embodiments, the luminescent material can be one of the following: phosphor, luminescent powder, reflective powder, thermochromic powder, pearlescent powder, photochromic powder, or phosphorescent powder. Thus, by adding these luminescent materials to the luminescent layer 30, the luminescent car cover 1 can emit light in its natural state, after receiving light, or when the temperature changes. For example, phosphor and luminescent powder can fluoresce in the dark after receiving light; reflective powder can reflect light and improve nighttime visibility; pearlescent powder contains mica or natural pearl components and can reflect light to produce a pearly luster; thermochromic powder can produce different colors depending on the temperature.

[0048] In some embodiments, the functional layer 40 may be one or more layers. For example, the functional layer 40 may be one to ten layers. In this case, the film thickness can be controlled by increasing or decreasing the number of functional layers according to the user's requirements for film thickness.

[0049] In some embodiments, when the functional layer 40 is multi-layered, the thickness of each functional layer can be from 50 micrometers to 300 micrometers.

[0050] In some embodiments, the silicone rubber layer or hybrid layer is formed by coating an adhesive layer with liquid silicone rubber, liquid silicone resin, or a mixture of liquid silicone rubber and liquid silicone resin. The liquid silicone rubber, liquid silicone resin, or mixture of liquid silicone rubber and liquid silicone resin may be dried in a drying apparatus to form the functional layer 40.

[0051] In some embodiments, the multilayer functional layer is preferably three layers, for example, the multilayer functional layer may include a first functional layer, a second functional layer, and a third functional layer stacked sequentially. A first liquid silicone can be coated on the adhesive layer 10 to form a first functional layer on the adhesive layer 10; a second liquid silicone can be coated on the side of the first functional layer away from the adhesive layer 10 to form a second functional layer on the first functional layer; and a third liquid silicone can be coated on the side of the second functional layer away from the first functional layer to form a third functional layer on the second functional layer. The compositions of the first liquid silicone, the second liquid silicone, and the third liquid silicone can be the same or different.

[0052] In some embodiments, the TPU layer 20 may include one or more TPU films. Thus, by setting different numbers of TPU layers, the luminous car cover can have a certain thickness and texture.

[0053] In some embodiments, the luminous car cover 1 may further include a tactile layer, which may be disposed on the side of the functional layer away from the TPU layer. Thus, by using the tactile layer as the outermost layer, the tactile feel of the luminous car cover can be improved.

[0054] In some embodiments, an adhesive may be applied between the TPU layer 20 and the functional layer 40. This enhances the adhesion between the functional layer 40 and the TPU layer 20, thereby improving the bonding strength between them.

[0055] In some embodiments, the adhesive treatment agent may be glue, instant glue, UV glue, OCA glue, TPU treatment agent CL-25T, etc.

[0056] In some embodiments, the functional layer 40 and the TPU layer 20 can be transparent. This enhances the reflectivity of the luminescent car cover 1, increasing the brightness inside the car when applied to the interior; and allows the luminescent layer 30 to absorb more light through the functional layer 40 and the TPU layer 20, enabling it to emit sufficient fluorescence in dark environments.

[0057] In some embodiments, the functional layer 40 can be transparent, and the TPU layer 20 can be opaque. This allows the color of the TPU layer 20 to be fully displayed through the functional layer 40.

[0058] In some embodiments, the luminous car cover 1 may further include a self-healing coating, which may be disposed on the side of the functional layer 40 away from the luminous layer 30. In which case, by providing a self-healing coating on the surface of the functional layer 40, a self-healing function for indentations, etc., can be achieved, and the smoothness of the surface of the luminous car cover 1 can be maintained.

[0059] In some embodiments, the self-healing coating may be a hydrogel film. The hydrogel film may be adhered to the surface of the functional layer 40 by adsorption.

[0060] In some embodiments, a hydrophobic agent, a scratch-resistant agent, a UV-resistant agent, and a weather-resistant agent may be added to the liquid silicone. In this case, the hydrophobic agent can improve the hydrophobic properties of the luminous car cover 1, the scratch-resistant agent can improve the scratch-resistant properties of the luminous car cover 1, the UV-resistant agent can improve the UV resistance of the luminous car cover 1, and the weather-resistant agent can improve the weather resistance of the luminous car cover 1.

[0061] In some embodiments, the hydrophobic agent may be an organosilicon resin, such as polydimethylsiloxane (PPMS); the hydrophobic agent may also be a fluorinated silane, such as trifluoropropyltrichlorosilane.

[0062] In some embodiments, the anti-scratch agent may be silica nanoparticles or a polyurethane (PU) modifier.

[0063] In some embodiments, the UV stabilizer can be a UV absorber (UVA), such as a benzotriazole compound; the UV stabilizer can also be a light stabilizer (HALS), such as a hindered amine light stabilizer.

[0064] In some embodiments, the weathering agent may be an antioxidant, such as a hindered phenolic antioxidant; the weathering agent may be a light stabilizer, such as HALS or other benzotriazoles.

[0065] In some embodiments, at least one silicone rubber layer may be disposed between the functional layer 40 and the TPU layer 20. This at least one silicone rubber layer serves to provide bonding and abrasion resistance. In some embodiments, the color of the at least one silicone rubber layer may be transparent, colored, or otherwise. In some embodiments, the multilayer silicone rubber layer may include both colored and transparent silicone rubber layers.

[0066] In some embodiments, the luminous car cover 1 may further include a VMQ silicone resin layer. The VMQ silicone resin layer may be disposed on the side of the functional layer 40 away from the TPU layer 20. The VMQ silicone resin layer may also serve as a replacement layer for the functional layer 40. In this case, using the VMQ silicone resin layer as the outermost layer of the luminous car cover 1 can improve the hydrophobicity, transparency, and tactile feel of the luminous car cover.

[0067] In other embodiments, the functional layer 40 may be made of a mixture of liquid silicone rubber and liquid silicone resin. This allows for the full integration of the properties of both liquid silicone rubber and liquid silicone resin.

[0068] In some embodiments, the liquid silicone forming the functional layer 40 may further include dyes, dispersants, and additives. In this case, by adding dyes to the liquid silicone, the resulting functional layer 40 can have different colors, which can enhance the visual appeal of the luminescent car cover 1. Adding dispersants and additives can ensure that the dyes are evenly distributed in the liquid silicone.

[0069] In some embodiments, the TPU layer 20 can be a HERZI TPU color-changing film (thermoplastic polyurethane color-changing film). In this case, because the HERZI TPU color-changing film can offer a wider range of colors compared to ordinary illuminated car wraps—for example, HERZI TPU color-changing film can easily achieve cool metallic colors, deep matte colors, and fashionable gradient colors—it can greatly enhance the user's visual appeal and experience, especially when illuminated car wraps are used in automotive interiors. When the TPU layer 20 is a HERZI TPU color-changing film, the functional layer 40 is preferably a film with high transparency. This highlights the color characteristics of the HERZI TPU color-changing film.

[0070] In some embodiments, when the TPU layer 20 can be a HERZI TPU color-changing film, an additional backing layer is not required. The colored HERZI TPU color-changing film can replace the backing layer to achieve the color-developing effect.

[0071] In some embodiments, the color of the functional layer 40 can be adapted to the color of the TPU layer 20. This enhances the overall aesthetic appeal of the luminous car cover 1.

[0072] The functional layer 40 and the light-emitting layer 30 of this invention are made of organosilicon. In this case, organosilicon has advantages over ordinary silicon, such as anti-fouling, high and low temperature resistance, weather resistance, hydrophobicity, and antibacterial properties. When the functional layer is made of organosilicon, the light-emitting car cover can have good anti-fouling, high and low temperature resistance, weather resistance, hydrophobicity, and antibacterial properties.

[0073] Reference Figure 2 In some embodiments, the luminous car cover 1 may further include a release layer 50. The release layer 50 can serve as a substrate and can be removed when the luminous car cover 1 is used. Taking its use as a car cover as an example, the side with the adhesive layer 10 can be adhered to the car after the release layer 50 is removed.

[0074] The method for preparing the luminescent car cover of this utility model is as follows: an adhesive is applied to the release layer 50 to form an adhesive layer 10 on the release layer; a TPU layer 20 is attached to the side of the adhesive layer 10 away from the release layer 50; a liquid organosilicon mixed with phosphor is applied to the side of the TPU layer 20 away from the adhesive layer 10 to form a light-emitting layer 30 on the TPU layer 20; and a functional layer 40 is provided on the side of the light-emitting layer 30 away from the TPU layer 20.

[0075] In some embodiments, the adhesive may be dried by a drying device to form an adhesive layer 10.

[0076] In some embodiments, the luminous car cover 1 may further include a protective layer. The protective layer may be disposed on the side of the functional layer 40 away from the TPU layer 20. In this case, the luminous car cover 1 can be peeled off during use, and the protective layer, as the outermost layer, serves to protect against and reduce wear.

[0077] According to this utility model, a luminescent car cover 1 can be provided, which has strong tensile, tensile, toughness and aging resistance, is not easy to oxidize and turn yellow, is environmentally friendly and is also stain-proof, hydrophobic, scratch-proof, UV-resistant and weather-resistant.

[0078] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
