Description

Technical Field

[0001] This utility model belongs to the field of protective film technology, specifically relating to a paint surface protective film with pearlescent layer variations. Background Technology

[0002] Besides protecting the original paint and preserving its gloss and brightness, paint protection films enhance the user experience by adding a colorant coating between the substrate and the adhesive layer. Specifically, the colorant is dispersed in resin to create a color layer, which is then laminated to both sides of the substrate and adhesive layer. This allows for low-cost, small-batch production of various colored paint protection films, resulting in vibrant colors and a wide range of color adjustments. The colorant can be one or more of various pigments, including ordinary pigments, pearlescent pigments, fluorescent pigments, and metallic pigments. Pearlescent pigments, in particular, are pigments that produce a pearly luster by coating mica flakes with metal oxides.

[0003] To enrich the pearlescent effect, existing methods involve placing a base layer between the pearlescent color layer and the original paint surface to cover the original paint, thus ensuring that the pearlescent effect is not affected by the color of the original paint. For example, CN116606599A discloses a polyurethane color-changing car wrap and its preparation method. The base layer is a gray, white, or black coating of PU or modified PU base material, which gives the color-changing layer above the base layer a bright and full color effect. However, both the pearlescent color layer and the base layer are planar structures, and the pearlescent effect lacks a three-dimensional sense of layering. Utility Model Content

[0004] In view of the shortcomings of existing paint protection films, such as the lack of three-dimensional layering and monotonous visual effect of pearlescent effect, the purpose of this utility model is to provide a car paint protection film with varying pearlescent layers. This car paint protection film has a fluffy powder layer with matte properties and a pearlescent layer with rich pearlescent layers. When the two are superimposed, they show a soft luster and a visual effect of varying pearlescent layers through a highly transparent substrate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paint protection film with varying pearlescent layers, comprising, from bottom to top, a release protective film layer, an adhesive layer, a color layer, a substrate layer, a functional coating layer, and a coating protection layer; the color layer includes a fluff powder layer and a pearlescent layer disposed above the fluff powder layer; the fluff powder layer includes a first resin layer and fluff powder dispersed in the first resin layer; the pearlescent layer includes a second resin layer and pearlescent color powder dispersed in the second resin layer.

[0006] Furthermore, the particle size of the fluff powder is greater than the thickness of the first resin layer; the sum of the thicknesses of the first resin layer and the second resin layer is greater than the particle size of the fluff powder.

[0007] Furthermore, the thickness of the second resin layer is 15–35 μm.

[0008] Furthermore, the average particle size of the fluff powder is 20–40 μm, and the thickness of the first resin layer is 15–35 μm.

[0009] Furthermore, the substrate is a polyurethane elastomer.

[0010] Furthermore, the pearlescent pigment in the pearlescent layer has a mass percentage of 2% to 5%.

[0011] Furthermore, the mass percentage of the fluff powder in the fluff powder layer is 10% to 30%.

[0012] Furthermore, the first resin layer is one or a mixture of two of polyurethane resin and acrylic resin.

[0013] Furthermore, the second resin layer is one or a mixture of two of polyurethane resin and acrylic resin.

[0014] Furthermore, the functional coating is one or more of a hydrophobic coating, an antifouling coating, and a self-healing coating, or a mixture thereof.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) By adding fluff powder to the first resin layer to form a fluff powder layer and the second resin layer to wrap the fluff powder in the form of microspheres, the thickness of the second resin layer is uneven. The second resin layer contains flake-shaped pearlescent pigment. The uniform and regular variation in the thickness of the second resin layer results in different pearlescent pigment content in different thickness areas of the second resin layer, and different pearlescent effects are presented. The part with more pearlescent pigment content has obvious glitter effect and has the effect of clustered glitter points. The part with less and more dispersed pearlescent pigment content has a more subtle glitter effect and has a starlight glitter effect. The pearlescent pigment with uniformly varying content in the pearlescent layer can be seen through the highly transparent substrate. The pearlescent effect of the pearlescent layer is rich in layers.

[0017] (2) The matte powder layer and the pearlescent layer with rich pearlescent layers achieve both matte and pearlescent effects. When the two are superimposed, they reveal a soft luster and a visual effect of varying pearlescent layers through a highly transparent substrate. The pearlescent layer is used to wrap the powder in the powder layer to prevent the powder from affecting the smoothness of the entire paint protective film. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the structure of this utility model;

[0019] Among them, 1 is the release protective film layer, 2 is the adhesive layer, 3 is the color layer, 4 is the substrate layer, 5 is the functional coating, 6 is the coating protection layer, 31 is the fluff powder layer, 32 is the pearlescent layer, 311 is the first resin layer, 312 is the fluff powder, 321 is the second resin layer, and 322 is the pearlescent color powder. Detailed Implementation

[0020] To clearly, accurately, and completely express the technical means of realizing this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings.

[0021] This invention adds a color layer between the substrate and the adhesive layer. The color layer includes a fluff powder layer and a pearlescent layer disposed above the fluff powder layer. The fluff powder layer includes a first resin layer and fluff powder dispersed in the first resin layer. The pearlescent layer includes a second resin layer and pearlescent color powder dispersed in the second resin layer.

[0022] The fluff powder is a powder composed of elastic polymer microspheres. It has a low specific gravity and can be uniformly dispersed and arranged in a regular pattern within the first resin layer. The particle size of the fluff powder is larger than the thickness of the first resin layer, and some of the fluff powder protrudes from the upper surface of the first resin layer. A pearlescent layer is formed by coating a second resin layer containing pearlescent pigments on top of the fluff powder layer. The sum of the thicknesses of the second and first resin layers is greater than the particle size of the fluff powder. The second resin layer, encapsulating the microsphere-like fluff powder, results in an uneven thickness. The second resin layer contains flake-like pearlescent pigments. In areas with greater thickness within the second resin layer, the pearlescent pigment content is higher, resulting in concentrated pearlescent effect, while in areas with less thickness, the pearlescent pigment content is lower, resulting in dispersed pearlescent effect, creating a rich and layered pearlescent effect.

[0023] The velvet powder has matte properties, giving the velvet powder layer a soft, matte sheen and achieving a matte effect. The pearlescent layer has rich pearlescent layers, achieving a pearlescent effect. When the soft, matte velvet powder layer and the pearlescent layer with rich pearlescent layers are superimposed, they reveal a soft sheen and a visual effect of varying pearlescent layers through a highly transparent substrate. Furthermore, the pearlescent layer encapsulates the velvet powder in the velvet powder layer, preventing the velvet powder from affecting the smoothness of the entire paint protective film.
