Description

Technical Field

[0001] The present invention relates to the technical field of optical decoration parts, and in particular to a wood grain film and a texture cover plate. Background Art

[0002] Textured cover is a decorative material used in the design of the interior space of the car. It is widely used in many key parts such as door panels, instrument panel panels, auxiliary instrument panel panels, seat facings, and steering wheel wrapping. It can provide a variety of visual and tactile experiences, such as metal texture, technological texture, wood grain, etc. With rich color matching, pattern design and texture changes, textured cover has become an important element in shaping different in-car brand images, from luxurious and elegant to dynamic and energetic.

[0003] As an emerging environmentally friendly decorative film material, wood grain film has a wide range of applicability and can be tightly attached to a variety of substrates such as metal, plastic, and wood to form a highly realistic textured cover with imitation wood grain effect. However, the wood grain films currently circulating on the market generally have a significant defect, that is, their light transmittance is relatively limited, resulting in a relatively dim decorative effect, not bright and clear enough, which may affect the overall aesthetics of the interior of the car. In particular, when the wood grain film needs to be applied to areas such as instrument panel trim that need to be light-transmitting to display patterns, text or lighting effects, its low light transmittance often leads to poor display effects of patterns, text or lighting, which not only weakens the decorative artistic expression, but may also interfere with the driver's accurate reading of information, thereby posing a potential threat to driving safety.

[0004] In view of the above problems, it is particularly urgent to optimize and improve the current wood grain film technology.

[0005] The above information is presented as background information only to assist with understanding the present disclosure and no determination or admission is made as to whether any of the above may be used as prior art with respect to the present disclosure. Summary of the invention

[0006] The invention provides a wood grain film and a texture cover plate to solve the problems existing in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] In a first aspect, the present invention provides a wood grain film, comprising a base film 4 and an ink layer disposed on the base film 4, wherein the ink layer is composed of a plurality of mother balls 1, and the surface of the mother ball 1 comprises a first surface 2 and a second surface 3 disposed opposite to each other;

[0009] The first surface 2 is a reflective surface, and when light is irradiated onto the first surface 2, reflection occurs;

[0010] The second surface 3 is a refractive surface. When light is irradiated onto the second surface 3 , it is refracted, enters the mother ball 1 , and then exits from the first surface 2 .

[0011] Furthermore, in the wood grain film, the reflective surface is a rough surface.

[0012] Furthermore, in the wood grain film, the rough surface is obtained by a smooth surface reacting with gas.

[0013] Furthermore, in the wood grain film, the gas is nitrogen.

[0014] Furthermore, in the wood grain film, the rough surface is obtained by spraying a substance on the smooth surface.

[0015] Furthermore, in the wood grain film, the substance is composed of the following raw materials in percentage by mass:

[0016] Methacrylic acid 80%;

[0017] Pentamethylene glycol 13%;

[0018] Cyclobutyl methyl ketone 7%.

[0019] Furthermore, in the wood grain film, the refractive surface is a smooth surface, and the refractive index of the mother ball 1 is higher than the refractive index of the air and the base film 4 respectively.

[0020] Furthermore, in the wood grain film, the ink layer is formed on the surface of the base film 4 by spraying.

[0021] Furthermore, in the wood grain film, the material of the mother ball 1 is divinylbenzene resin.

[0022] In a second aspect, the present invention provides a textured cover plate, comprising a substrate 100 and a wood grain film 200 as provided in the first aspect above; wherein:

[0023] The wood grain film 200 is disposed on the surface of the substrate 100 .

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention provides a wood grain film and a texture cover plate. By designing the first surface of the mother ball as a reflective surface and the second surface opposite to the first surface as a refractive surface, when the first surface faces outward and the second surface faces inward, the first surface can reflect light in the environment, and the second surface can refract light emitted by the light source into the mother ball and then emit it from the first surface, so that the light transmittance can be greatly improved, and the brightness and clarity of the decorative effect can be improved, which is beneficial to the overall aesthetics and the driver's accurate reading of information, and is suitable for large-scale promotion and application.

[0043] Embodiment 1

[0044] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0045] Please refer to Figure 1-2 The embodiment of the present invention provides a wood grain film, comprising a base film 4 and an ink layer disposed on the base film 4, wherein the ink layer is composed of a plurality of mother balls 1 (the mother balls 1 are ink molecules after being colored), and the surface of the mother balls 1 comprises a first surface 2 and a second surface 3 disposed opposite to each other;

[0046] The first surface 2 is specially designed as a reflective surface, and its function is that when light in the environment is projected onto this surface, a reflection phenomenon will occur, thereby effectively reflecting the light in a specific direction.

[0047] The second surface 3 is designed as a refractive surface. When the light emitted by the light source (such as the light diode of the screen) touches this surface, a refraction effect occurs, and the light enters the interior of the mother ball 1 and is finally emitted from the first surface 2 after being conducted through the internal path.

[0048] The innovation of the embodiment of the present invention is that the first surface 2 of the mother ball unit 1 is designed as a reflective surface, and the second surface 3 opposite thereto is designed as a refractive surface. This unique design enables the light of the external environment to be effectively reflected through the first surface 2 as much as possible when the first surface 2 faces outward and the second surface 3 faces inward, while the light of the light source passes through the base film 4 as much as possible and then refracts through the second surface 3, enters the interior of the mother ball 1, and finally emits from the first surface 2. These designs not only greatly improve the light transmission efficiency, but also significantly enhance the brightness and clarity of the decorative effect, thereby greatly promoting the improvement of the overall aesthetics and ensuring that the driver can read relevant information accurately.

[0049] In one implementation of this embodiment, the reflective surface is a rough surface.

[0050] It should be noted that the rough reflective surface can produce more complex and diverse reflection effects when exposed to light compared to the smooth surface. This scattered reflection not only enhances the interaction between light and the material surface, but also further enriches the visual layering, allowing the wood grain film to present a delicate wood grain texture while also showing more vivid and three-dimensional light and shadow changes.

[0051] In addition, the rough reflective surface can also help reduce the occurrence of glare, which is crucial to improving visual comfort during driving. When drivers face strong sunlight, the rough reflective surface can effectively disperse the light and avoid discomfort or safety hazards caused by direct light.

[0052] In summary, designing the reflective surface as a rough surface not only improves the decorative effect of the wood grain film, but also enhances its practicality and safety in actual applications.

[0053] In one implementation of this embodiment, a novel method is explored to prepare the rough surface. The core of this method is to use the smooth surface to react with a specific gas, and through this chemical reaction process, the originally smooth surface will be transformed into a rough surface with a specific roughness.

[0054] This chemical reaction-induced surface roughening process not only provides a new way to prepare rough surfaces, but also gives the rough surfaces unique physical and chemical properties. Due to the interaction between the gas and the smooth surface, the rough surface formed after the reaction often has a more uniform roughness distribution and a richer microstructure. These properties enable the rough surface to show more delicate and rich light and shadow effects under light, further enhancing the visual beauty of the wood grain film.

[0055] At the same time, the rough surface prepared by this chemical reaction also has good durability and stability. Since the rough structure is directly embedded in the material surface through chemical reaction, it is less susceptible to wear or damage compared to other physical or mechanical treatment methods, thus ensuring the decorative effect and performance stability of the wood grain film during long-term use.

[0056] In summary, the method of preparing a rough surface by contacting a smooth surface with gas not only provides more possibilities for the design and production of wood grain films, but also further improves its comprehensive performance in practical applications.

[0057] In one implementation of this embodiment, nitrogen is selected as the gas for contact reaction with the smooth surface. This selection is not accidental, but is based on the unique chemical properties and reaction characteristics of nitrogen.

[0058] Nitrogen is an inert gas and is usually not easy to react chemically with other substances. However, under certain conditions, such as high temperature, high pressure or the presence of a catalyst, nitrogen can react chemically with the surface of certain materials to form unique chemical bonds and surface structures. In this embodiment, the reactivity of nitrogen with smooth surfaces under certain conditions is utilized. By precisely controlling the reaction conditions, nitrogen reacts with the smooth surface, thereby forming a layer of microstructure with a specific roughness on the surface.

[0059] This nitrogen reaction-induced surface roughening process not only provides a new method for preparing rough surfaces, but also gives the rough surfaces unique properties. Since the chemical bonds formed between nitrogen and the material surface are usually stable, this rough surface has excellent durability and wear resistance. At the same time, nitrogen reaction may also introduce some special chemical groups or functions, which may further affect the optical properties, weather resistance or compatibility of the wood grain film with other materials.

[0060] In summary, by selecting nitrogen as the gas for contact reaction with the smooth surface, it not only provides a new idea and method for the design and production of wood grain films, but also further expands the application field and performance range of wood grain films.

[0061] In one implementation of this embodiment, in addition to using a gas reaction method to prepare a rough surface, a spraying technique can also be used to prepare a rough surface. Specifically, this method involves uniformly spraying a layer of a specific substance on a smooth surface, and through the deposition and curing process of this layer of substance, a surface layer with a rough structure is formed on the smooth surface.

[0062] The choice of spray material is crucial. It must not only form a good bond with the smooth surface, but also form a surface with the desired roughness after curing. To achieve this goal, granular substances with a specific particle size distribution, resins, polymers or other materials that can form a rough surface may be selected. During the spraying process, these substances are evenly sprayed onto the smooth surface and form a dense, rough-structured coating on the surface through processes such as heating, drying or natural curing.

[0063] The roughened surface produced by this spraying method has many advantages. First, it can adjust the type and particle size distribution of the sprayed material as needed, thereby accurately controlling the morphology and roughness of the roughened surface. Second, the spraying process is simple and efficient, suitable for large-scale production. In addition, since the bonding force between the sprayed material and the smooth surface is usually strong, this roughened surface has good durability and wear resistance.

[0064] In summary, the method of preparing a rough surface by spraying a specific substance on a smooth surface not only provides a simple and efficient preparation method, but also enables the customization of surface structures with different roughness and morphology according to specific needs, thereby further enriching the design and application scope of wood grain films.

[0065] In one embodiment of this example, the precise formula of the substance used for spraying to form a rough surface is described in detail. The substance is carefully prepared from the following raw materials in precise mass percentages:

[0066] Methacrylic acid, C 4 H 6 O 2 , accounting for up to 80%. As an important organic compound, methacrylic acid has excellent chemical stability and reactivity, and is a key raw material for the preparation of high-performance polymers and coating materials. In this formula, the high content of methacrylic acid ensures that the prepared coating has excellent adhesion and durability, and also helps to form a uniform and dense rough structure.

[0067] Pentamethylene glycol, C 5 H 12 O 2 , accounting for 13%. As a diol, pentamethylene glycol has good solubility and reactivity, and can copolymerize with monomers such as methacrylic acid to enhance the flexibility and weather resistance of the coating. In the formula, the addition of pentamethylene glycol helps to adjust the hardness and elasticity of the coating, making it more adaptable to the needs of different application scenarios.

[0068] Cyclobutyl methyl ketone, C 6 H 10 O, accounting for 7%. As an organic solvent, cyclobutyl methyl ketone has low volatility and good solubility, and can effectively dissolve and disperse raw materials such as methacrylic acid and pentamethylene glycol to form a uniform spray solution. At the same time, the addition of cyclobutyl methyl ketone also helps to adjust the drying speed and curing process of the coating, thereby ensuring that the prepared rough surface has ideal morphology and performance.

[0069] In summary, by precisely controlling the mass percentages of raw materials such as methacrylic acid, pentamethylene glycol and cyclobutyl methyl ketone, a spray material with excellent performance can be successfully prepared. After spraying, the material can form a surface layer with a specific roughness, which not only enhances the visual effect and tactile experience of the wood grain film, but also improves its durability and wear resistance.

[0070] In one implementation of this embodiment, the refractive surface is a smooth surface, and the refractive index of the mother ball 1 is higher than the refractive index of air and the base film 4 .

[0071] Specifically, the refractive surface is the interface when light enters another medium from one medium, and its surface morphology has a crucial influence on the propagation path and refraction effect of the light. In this embodiment, the refractive surface is designed to be a smooth surface, which allows the light to undergo a more regular and controllable refraction phenomenon when it contacts the refractive surface.

[0072] At the same time, in order to ensure that light can smoothly enter the interior of the mother ball 1 from the medium such as air or the base film 4, a mother ball material with a refractive index higher than that of air and the base film 4 is specially selected. In fact, in order to allow light to better penetrate into the mother ball 1, it is usually necessary that the refractive index of the material of the mother ball 1 is slightly higher than that of air (the refractive index of air is approximately 1) and the base film 4. In this way, when light is obliquely incident from air and / or the base film 4 to the refractive surface of the mother ball 1, according to Snell's Law, the light will be deflected in the normal direction, that is, the shell is refracted into the interior of the mother ball 1.

[0073] In addition, the smooth and high refractive index refractive surface can also help reduce the scattering and loss of light during the propagation process, thereby improving the utilization and transmission efficiency of light. This feature is crucial to improving the transmittance and clarity of the wood grain film. It can not only enhance the visual effect of the wood grain film, but also ensure that the driver can clearly read the screen information during driving, thereby improving driving safety.

[0074] In summary, by designing the refractive surface to be a smooth surface and selecting a mother ball material with a higher refractive index than air, an efficient and reliable light refraction mechanism is successfully achieved.

[0075] In one implementation of this embodiment, the mother ball 1 is made of divinylbenzene resin.

[0076] It should be noted that divinylbenzene resin, as a high-performance thermosetting resin, has excellent chemical stability and thermal stability. It can maintain a stable structure at high temperatures and is not prone to deformation or decomposition, thereby ensuring that the mother ball 1 can maintain stable optical properties during long-term use. In addition, divinylbenzene resin also has good weather resistance and can resist erosion by environmental factors such as ultraviolet rays and humidity, further extending the service life of the wood grain film.

[0077] In terms of optical properties, the refractive index of divinylbenzene resin is higher than that of air, which enables significant refraction of light when it enters the mother ball 1 from the air. At the same time, its smooth surface morphology also helps to reduce the scattering and loss of light, and improve the utilization and transmission efficiency of light. This feature makes the mother ball 1 perform well in light conduction and refraction, providing excellent visual effects for the wood grain film.

[0078] In addition, the divinylbenzene resin also has good mechanical properties, such as high hardness and toughness, which enables the mother ball 1 to maintain a stable shape and structure when subjected to external forces and is not easily damaged or deformed. This feature ensures that the wood grain film can maintain stable performance during use and improves its reliability and durability.

[0079] In summary, the selection of divinylbenzene resin as the material of the mother ball 1 is not only based on its excellent performance in optical, thermal, and mechanical properties, but also fully considers the needs of the wood grain film in practical applications.

[0080] In one implementation of this embodiment, the ink layer is formed on the surface of the base film 4 by spraying.

[0081] It should be noted that this embodiment uses spraying technology to accurately form the ink layer on the surface of the base film 4. This method not only simplifies the production process and improves production efficiency, but also ensures close bonding and uniform distribution between the ink layer and the base film 4.

[0082] As a mature surface treatment technology, spraying technology has the advantages of simple operation, low cost, and wide application range. In this embodiment, a carefully prepared ink layer is evenly sprayed on the surface of the base film 4 using a spraying device. By accurately controlling spraying parameters such as spraying speed, spraying distance, spraying pressure, etc., the ink layer can be accurately deposited and solidified on the surface of the base film 4.

[0083] The ink layer formed by spraying not only has excellent adhesion and durability, but also can present delicate and realistic wood texture. This feature is due to the carefully designed mother ball structure in the wood grain film material and the precise ratio of the spraying material. During the spraying process, the reflective and refractive surfaces in the mother ball structure can fully demonstrate its optical properties, so that the ink layer can present rich light and shadow effects under light, further enhancing the visual beauty of the wood grain film.

[0084] In addition, spraying technology also allows the ink layer to flexibly adapt to base films of different shapes and sizes4. Whether it is a flat surface, a curved surface or a complex surface, the ink layer can be evenly covered by spraying technology. This feature provides more possibilities for the design and manufacture of wood grain films, making it widely used in automotive interiors, furniture decoration, electronic product housings and other fields.

[0085] In summary, by using the spraying technology to form the ink layer on the surface of the base film 4, an efficient, precise and flexible method for manufacturing wood grain films has been successfully realized. This innovative method not only improves production efficiency and reduces production costs, but also brings more possibilities for the design and application of wood grain films.

[0086] Although the terms such as cue ball and surface are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0087] The present invention provides a wood grain film, in which the first surface of the mother ball is designed as a reflective surface, and the second surface opposite to the first surface is designed as a refractive surface, so that when the first surface faces outward and the second surface faces inward, the first surface can reflect the light in the environment, and the second surface can refract the light emitted by the light source into the mother ball and then emit it from the first surface, so that the light transmittance can be greatly improved, and the brightness and clarity of the decorative effect can be improved, which is beneficial to the overall aesthetics and the driver's accurate reading of information, and is suitable for large-scale promotion and application.

[0088] Embodiment 2

[0089] Please refer to Figure 3 The second embodiment of the present invention provides a texture cover plate, comprising a substrate 100 and a wood grain film 200 as provided in the first embodiment above; wherein,

[0090] The wood grain film 200 is disposed on the surface of the substrate 100 , thereby giving the texture cover board unique aesthetics and functionality.

[0091] Specifically, the substrate 100, as the main structure of the texture cover, bears the important responsibility of supporting and protecting the wood grain film 200. It may be made of various materials, such as metal, plastic, glass or other composite materials, depending on the application scenario and performance requirements of the texture cover. The choice of substrate 100 not only affects the overall strength and durability of the texture cover, but also has an important impact on its processing performance and cost-effectiveness.

[0092] The wood grain film 200, as a key element in this embodiment, brings realistic wood texture and touch to the texture cover. It adopts the special design described in detail in the above embodiment 1, that is, a cue ball structure with a reflective surface and a refractive surface. These innovative designs enable the wood grain film 200 to show delicate and rich light and shadow effects under light, further enhancing the visual beauty of the texture cover.

[0093] The wood grain film 200 is arranged on the surface of the base 100, which not only realizes a close combination between the two, but also ensures the stability and reliability of the texture cover during long-term use. This combination not only retains the excellent performance of the wood grain film 200, such as weather resistance, wear resistance and easy cleaning, but also further improves the overall performance and service life of the texture cover through the support and protection of the base 100.

[0094] In summary, the texture cover provided in the second embodiment of the present invention, by ingeniously combining the substrate 100 and the wood grain film 200 in the first embodiment, achieves the goal of giving the texture cover unique aesthetics and functionality while maintaining excellent performance. This innovative design not only meets the user's dual needs for beauty and practicality, but also provides new ideas and methods for the design and manufacture of texture cover.
