Description

This creation is related to a colorful structure, especially a colorful structure with dispersion phenomenon.

Generally speaking, with the advancement of existing technologies such as electroplating, deposition and other processes, there are also various technologies that can be applied to the surface treatment of processed objects. For example, through the adjustment of various process parameters of coating to change its appearance and color, this is also different from traditional methods such as chemical coating or spray painting. For example, for the appearance of general mobile phones, in order to achieve the special purpose of reducing the weight of the mobile phone, the part of the mobile phone shell is usually made of reinforced plastic material, but in order to maintain the visual effect of the appearance or color such as metallic luster, It is also done by plating a film containing metal components.

However, if the exterior of the casing is to be plated with a coating containing metallic components or even rare earth metals for the aforementioned visual effect of metallic luster, in the process of adjusting the visual effect, a composite metal of multiple or multilayer metals is usually used. Being able to adjust the visual effects will make it difficult to reduce the overall production cost. And it is easy to generate great internal stress during the processing of the composite metal and the substrate, which in turn affects the overall durability.

For this reason, how to design a colorful structure with dispersion phenomenon, especially to solve the technical problems of the overall production cost and internal stress of the existing technology is difficult to reduce, which is an important subject studied by the creators of this project.

The ultraviolet accelerator is used to respond to the ultraviolet spectrum and cause at least part of the ultraviolet coating to undergo a curing reaction. The sputtering layer and the dielectric layer are overlapped to generate an ultraviolet spectrum, and the sputtering layer includes at least one of a stacked metal layer and a reactive coating film. Wherein, the response includes a first response and a second response in sequence, the first response causes at least 70% of the volume or area of the ultraviolet coating to undergo a curing reaction, and the second response causes at least 30% of the volume or area of the ultraviolet coating to undergo a curing reaction. % Curing reaction occurs.

Furthermore, in the colorful structure with dispersion phenomenon, the ultraviolet coating and ultraviolet accelerator are applied by spraying, screen printing or three-dimensional printing, and the curing reaction of the ultraviolet coating is controlled to change the output from the dielectric layer. The spectrum band of visible light.

Furthermore, in the colorful structure with dispersion phenomenon, the metal layer and the reactive coating film are stacked on top of each other by continuous vacuum sputtering.

When using the colorful structure with dispersion phenomenon described in this creation, firstly, the dielectric layer and the substrate are superimposed. Since the dielectric layer includes ultraviolet paint and an ultraviolet accelerator for responding to the ultraviolet spectrum, it can be By controlling the curing reaction of the ultraviolet coating, the spectrum band of the visible light output from the dielectric layer can be changed. Then, the first response and the second response are performed in sequence. The first response causes a curing reaction of up to 70% of the volume or area of the ultraviolet coating, and the second response causes a curing reaction of at least 30% of the volume or area of the ultraviolet coating. Furthermore, the first response and the second response can be respectively controlled by controlling the output power or time of the ultraviolet spectrum, so as to produce different degrees of curing effects and stress changes in the volume or area of the ultraviolet coating, resulting in a change from the medium.

I believe that the features and characteristics of this creation can be obtained from this in-depth and specific understanding. However, the attached drawings are only provided for reference and explanation, and are not used to limit the creation.

The technical content and detailed description of this creation are described below with the diagrams.

Wherein, the dielectric layer 20 is stacked on the substrate 10, and includes a uniformly mixed ultraviolet paint (not shown in the figure) and an ultraviolet accelerator (not shown in the figure). Among them, the relative molecular mass of the ultraviolet coating is between 10,000 and 100,000, and the hardness of the characteristic characteristic of the ultraviolet coating is between 2B and 6B of the pencil hardness. The ultraviolet accelerator is used to respond to the ultraviolet (UV) spectrum and cause at least part of the ultraviolet coating to undergo a curing reaction.

In the first embodiment of the present creation, the response includes a first response and a second response that are performed in sequence. Among them, the first response causes at least 70% of the volume or area of the ultraviolet paint to undergo a curing reaction, and the second response causes at least 30% of the volume or area of the ultraviolet paint to undergo a curing reaction.

The first response may be provided by an independent ultraviolet device (not shown in the figure, such as an ultraviolet lamp) with an ultraviolet spectrum to the ultraviolet accelerator, so as to cause a curing reaction of the ultraviolet coating. The second response may be provided by an independent ultraviolet generator or sputtering layer in a vacuum chamber of continuous vacuum sputtering (in-line sputter) to provide ultraviolet spectrum to the ultraviolet accelerator, so as to cause the ultraviolet coating to undergo a curing reaction. For the UV coating after the curing reaction is completed (that is, the first response and the second response are completed), the structure generated inside the UV coating can disperse the natural light incident from the outside, and show a visual effect similar to metallic luster.

Furthermore, the ultraviolet spectrum used for the response may include UVA, UVB, UVC, and UVV bands, and the substrate 10 may include: at least one of metal, alloy, glass, and plastic or other polymer films.

The sputtering layer 30 overlaps the dielectric layer 20 and generates an ultraviolet spectrum that responds to the ultraviolet accelerator. The sputtering layer 30 includes at least one of a metal layer (not shown in the figure) and a reactive plating film (not shown in the figure) stacked on top of each other. Among them, the metal layer and the reactive coating film can be stacked on top of each other by continuous vacuum sputtering.

Please refer to Figure 2, which is a schematic diagram of the operation flow of continuous vacuum sputtering used in this creation. The continuous vacuum sputtering (in-line sputter) can be achieved by applying high-voltage negative electricity in a stable vacuum environment to dissociate the inert gas to form a plasma, and then through the action of a magnetic field applied to the target material, it can be ionized The positive ions of the inert gas in the plasma state bombard the surface of the target material, and then the surface layer atoms of the target material are impacted and sputtered, and deposited on the plated object to form a uniform continuous film. As shown in FIG. 2, the target material 1, the target material 2 and the substrate 100 are all arranged in a single vacuum chamber 3. First, the substrate 100 first deposits the substance of the target 1 as the first deposition layer 200, and then moves the substrate 100 to the corresponding position of the target 2 to deposit the substance of the target 2 as the second deposition layer 300. Since the substrate 100 does not leave the vacuum chamber 3 during the process of moving from the position corresponding to the target material 1 to the position corresponding to the target material 2, the gap between the first deposition layer 200 and the second deposition layer 300 can be ensured. It has good electrical contact and fewer lattice defects.
