Description

Technical Field

[0001] The utility model belongs to the technical field of protective films, and particularly relates to an automobile paint protective film with a texture effect. Background Art

[0002] The automobile paint protective film is pasted on the automobile body paint to protect the original factory paint. It is mainly composed of a base material, an adhesive layer and a coating. The coating determines the hydrophobicity, corrosion resistance and abrasion resistance of the paint protective film. The hydrophobic coating can automatically gather and slide when encountering water and oily substances, avoiding a large amount of water stains and water marks left on the paint surface after the evaporation of water after rain or car washing. A coating protective film is provided on the surface of the coating. In addition to protecting the coating before film application, the gloss, brightness and clarity of the paint protective film can also be adjusted according to different types of coating protective films.

[0003] The texture film is a coating protective film with a texture on the surface. It can transfer a texture structure on the surface of the coating, increasing the texture on the surface of the paint protective film, improving the product decoration, making the appearance more beautiful, and at the same time reducing the strong light reflection, not being too stimulating to people's eyes, and bringing a relaxed and pleasant sense of comfort. However, forming unevenness on the surface of a relatively thin coating may reduce the hydrophobic and corrosion resistance effects of the coating, and the texture structure is more likely to be worn during use, affecting the aesthetics.

[0004] The prior art adds a texture structure between the base material and the adhesive layer. For example, CN112251161B discloses an elastic body protective film with a pattern and its preparation method. By thermocompression of a film with a pattern and an elastic body base film, a concave pattern surface layer is formed, and then an adhesive is coated on the concave pattern surface layer to obtain an elastic body protective film with a pattern. However, directly bonding the film with a pattern and the elastic body base film by thermocompression has the problems that the heating and pressing effects are too large, the film with a pattern and the elastic body base film can be bonded, but the pattern is easily deformed after thermocompression, and the heating and pressing effects are too small, resulting in poor bonding between the film with a pattern and the elastic body base film and easy delamination. Summary of the Utility Model

[0005] Aiming at the technical deficiencies that the existing paint protective film has texture treatment on the outermost coating, which affects the coating performance, and the texture structure may be unstable or easily delaminated by thermocompression treatment of a film with a texture and a base material, the purpose of the utility model is to provide an automobile paint protective film with a texture effect, which can enhance the visual level and three-dimensional sense, and the texture structure is stable, and the scratch resistance effect can also be improved.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: An automotive paint protection film with a texture effect, comprising a substrate, coatings are respectively provided on both sides of the substrate, and on one side away from the substrate of one coating, a texture structure is formed by texture film transfer printing, and the other coating is laminated with a coating protection film without texture, and a glue layer is laminated on the texture structure.

[0007] Further, the texture structure includes a plurality of longitudinal stripe blocks and a plurality of transverse stripe blocks, the longitudinal stripe blocks include a number of uniformly arranged longitudinal stripes, and the transverse stripe blocks include a number of uniformly arranged transverse stripes.

[0008] Further, the coating is a polyurethane coating with a thickness of 5 - 15 μm.

[0009] Further, the substrate is a thermoplastic polyurethane substrate.

[0010] Further, the glue layer is a pressure - sensitive glue layer with a thickness of 30 - 35 μm.

[0011] Further, the texture film is a PET optical texture film.

[0012] Further, the coating protection film without texture is a PET optical film.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) By laminating an automotive paint protection film with a texture structure on the original factory paint color, the visual hierarchy and three - dimensional sense are enhanced; the texture structure is a combined arrangement of transverse stripe blocks and longitudinal stripe blocks, and different stripe directions present different light and dark effects, bringing a dynamic visual effect;

[0015] (2) On the basis of the traditional paint protection film, a coating with a texture structure is added. The denseness of the coating is beneficial to the stability of the texture structure and can also serve as another line of defense for the paint protection film, improving the anti - scratch effect; by using the texture structure, the bonding surface between the glue layer and the texture structure can be increased. The transverse stripes and longitudinal stripes of the present utility model can make the bonding effect of the glue layer and the texture structure balanced in two directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a structural schematic diagram of the present utility model;

[0017] Wherein, 1 is the substrate, 2 is the coating, 3 is the texture structure, 4 is the coating protection film, and 5 is the glue layer. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to clearly, accurately and completely express the technical means achieved by the present utility model, the present utility model will be further described below in conjunction with embodiments and drawings.

[0019] The present utility model coats coatings on both sides of the substrate respectively. One side of the coating serves as the first line of defense to protect the paint surface. It is located on the outermost side of the paint protection film, directly contacting the outside world, and preventing pollutants in the external environment from penetrating and eroding. The other side of the coating is used to make the texture structure. Since the coating has density, the texture structure is transferred to the coating through the texture film, which is more conducive to the stability of the texture structure. When sharp objects such as branches or keys scratch the outermost coating or even the substrate, this coating can also serve as another line of defense to protect the paint surface and reduce the degree of scratching.

[0020] The color of the original factory paint surface is reflected through the texture structure, and the texture structure reduces the specular reflection component. The directions of the longitudinal stripes and the transverse stripes are different. When observed in the same direction, the visual effects of the longitudinal stripe blocks and the transverse stripe blocks are different. When the observation direction is changed, the visual effects of the longitudinal stripe blocks and the transverse stripe blocks change respectively, having a dynamic visual effect. When an incident light irradiates on the surface of the paint protection film, the peaks of the longitudinal stripes and the transverse stripes are evenly illuminated. If the reflected light leaving the valleys between the longitudinal stripes is blocked by the stripes, the reflectivity of this part will be reduced and the glossiness will be low, presenting the color of the original factory paint surface darker. However, the reflected light leaving the concave parts between the transverse stripes is not blocked by the transverse stripes, and the visual effect of this part is brighter. The present utility model can form a distinct visual effect of light and dark through the combined arrangement of the longitudinal stripe blocks and the transverse stripe blocks, making the color of the original factory paint surface show hierarchical changes and being more ornamental.

[0021] Embodiment 1

[0022] The automotive paint protection film with a texture effect in this embodiment, as Figure 1 shown, is in sequence a non-textured coating protection film 4, a coating 2, a substrate 1, a coating 2 with a texture structure 3, an adhesive layer 5 and a PET release film. Coatings 2 are respectively provided on both sides of the substrate 1. One side of one coating 2 away from the substrate 1 is transferred through a texture film to form a texture structure 3, and the other coating 2 is laminated with a non-textured coating protection film 4 to form a planar structure. The texture structure 3 is laminated with an adhesive layer 5. Among them, the coating protection film 4 is a non-textured PET optical film with a thickness of 23 μm; the coating 2 is a polyurethane coating with a thickness of 15 μm; the substrate 1 is a thermoplastic polyurethane substrate with a thickness of 150 μm; the adhesive layer 5 is a pressure-sensitive adhesive layer with a thickness of 30 μm; and the thickness of the PET release film is 80 μm.

[0023] The texture structure 3 includes a plurality of longitudinal stripe blocks and a plurality of transverse stripe blocks. The longitudinal stripe blocks are composed of a number of uniformly arranged longitudinal stripes, and the transverse stripe blocks are composed of a number of uniformly arranged transverse stripes. The longitudinal stripe blocks have a length of 2 μm and a width of 0.5 μm, and the transverse stripe blocks have a length of 0.5 μm and a width of 0.5 μm. The longitudinal stripe blocks include three longitudinal stripes, and the transverse stripe blocks include three transverse stripes. The uniform arrangement of the longitudinal stripes and the transverse stripes is conducive to clear texture. In this embodiment, the minimum repeating unit of the texture structure is composed of five longitudinal stripe blocks and five transverse stripe blocks. Each transverse stripe block is not on the same horizontal line and is discontinuous in any direction, which can make the light and dark effects presented by the texture structure staggered and regularly uniform.

[0024] Two polyurethane coatings are respectively coated on both sides of the thermoplastic polyurethane substrate layer. One of the polyurethane coatings is laminated with the textured film, and a texture structure is formed on the surface of one of the polyurethane coatings. The other polyurethane coating is laminated with the non-textured coating protective film, and a planar structure is formed on the surface of the other polyurethane coating; after the textured film is removed, the texture structure is laminated with the adhesive layer coated on the PET release film to obtain an automotive paint protection film with a texture structure.

[0025] During use, the coating protective film and the PET release film are removed. The texture structure of this embodiment can reflect different visual effects on the light source, making the color of the paint surface present a staggered level change of light and dark, and improving the ornamental property.
