Abstract

A decorated molding article includes: forming an all-in-one coating on a substrate and performing a curing step, thereby forming a composite layer structure with a protective effect, a color effect, and a bonding effect. Compared with the printing layer in the conventional In Mold Label (IML) and InSert molding (INS) that is made by a plurality of anti-impact and bonding processes, the composite layer structure of the embodiment can form a molded film with better physical properties (e. g., higher hardness, better protection effect, etc.) after the blister molding process. Therefore, the molded film of the embodiment can be applied to a laser engraving process to form a variety of light-transmitting decorative molded products. Further, the present disclosure further forms a protective layer locally in the grooves formed after the laser engraving process, so as to protect the texture after the laser engraving process from damage.

Description

Light-transmitting decorative molded products

The novel creation relates to a light-transmitting decorative molded product.

Generally speaking, decorations such as patterns or characters formed on the surface of the object shell are mainly formed through spraying or printing processes, so as to present specific visual effects and increase the variability of the appearance of the object. The traditional forming method is to apply a hardened layer on the surface of the shell by spraying after the shell of the related product is completed. This method is cumbersome, has poor yield and will cause pollution of organic solvent gas, thus causing many pollution problems. On the other hand, due to the time-consuming, complicated process, and low thickness uniformity of the spraying process, the overall production yield and cost need to be improved urgently. In order to solve the aforementioned problems, a variety of specific decoration processes using decorative films have been proposed, such as in-mold decoration (In-Mold Decoration, IMD) or out-mold decoration (Out Mold Decoration, OMD). Another option.

At present, the commonly used polymer substrate materials in in-mold decoration technology include polycarbonate (Polycarbonate, PC), polymethyl methacrylate, also known as polyacrylic. (Poly(methyl methacrylate), PMMA), polyhexene terephthalate (PET, Polyethylene Terephthalate) and acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene, ABS). However, the hardness of the base material composed of PC and ABS is relatively low, which makes the surface of the base material prone to damage. Therefore, the hardness and scratch resistance of the base material surface are usually increased by coating a protective layer. On the other hand, the base material made of PMMA has high hardness, but it is easy to crack during molding, so it is not easy to carry out the hot pressing process.

In order to solve the aforementioned problems, a variety of specific decoration processes using decorative films have been proposed, such as in-mold decoration technology (In-Mold Decoration, IMD) or film out-of-film decoration technology (Out Mold Decoration, OMD). Another option.

Specifically, in-mold decoration technology (IMD) may include: In Mold Labeling (IML), In Mold Film (In Mold Film, IMF or INS) and In Mold Roller (IMR) , as shown in Table 1 below. The in-mold labeling (IML) process is characterized by a hardened transparent film on the surface, a printed pattern layer in the middle, and a plastic layer on the back. Because the ink is sandwiched between the hardened transparent film and the plastic layer, the product can prevent the surface from being scratched, wear-resistant, and can keep the color bright and not easy to fade for a long time. The IML process flow is as follows:

(1). Cutting: Take the roll-shaped film substrate (usually PMMA/PC or PET or PC substrate with hard coating), cut it into the designed size for printing and Blister molding use.

(2).Plane printing: usually screen printing (screen printing), spray printing process, providing icons and text The effect and the final anti-shock bonding material, and generally design the printing pass according to the effect of the product design diagram, especially the anti-shock bonding material needs to be matched with high-temperature and high-pressure injection molding plastic materials (generally, the injection molding temperature is about 200 degrees or more), usually requires Printing multi-pass stacking will lead to increased cost, lower film usage efficiency and lower overall yield.

(3). Ink drying: The printed ink is baked and dried at high temperature to ensure the physical properties of the ink.

(4).Pasting protective film: To prevent the post-punching positioning hole from damaging the surface of the printed film, a protective film must be attached to protect the surface.

(5). Punching positioning holes: Since the film will shrink during the forming and heating process, it is necessary to punch positioning holes to ensure the precision of the positioning of the printed film and matching products.

(6). High-temperature and high-pressure forming: After the printed film is subjected to high temperature and high heat, the forming machine is used for plastic absorption under preheating conditions.

(7). Cutting shape: Use cutting or laser cutting to cut off the waste after blistering.

(8).Injection molding: Finally, place the cut three-dimensional film on the injection molding machine for injection molding to form finished parts and physical inspection of related shipments.

The in-mold transfer (IMR) process is to print the pattern on the film, and then use the film feeder to attach the film to the mold cavity and perform injection molding. After injection, the ink layer with the pattern is separated from the film, and the ink layer is left in the film. A plastic part with a decorative pattern on the surface is obtained on the plastic part. Therefore, the surface of the final product of in-mold transfer does not have a layer of transparent protective film, and the film is only a carrier in the production process. In other words, the biggest difference between in-mold labeling (IML) and in-mold transfer (IMR) is whether there is a transparent protective film on the surface of the product. In addition, in-mold film (IMF) is the same as in-mold labeling (IML).

Out-of-film decoration technology (OMD), also known as high-pressure transfer printing. After printing the pattern on the transparent film, use high/medium/low pressure plus vacuum transfer printing to directly transfer the printing on the plastic casing. The main feature is the product with tactile sensation and it is used in 3C, home appliances and automobiles.

But regardless of IMD or OMD film, if you want to make light-transmitting decorative products, you will make them by printing and stacking. After the client goes through the processes of blistering, cutting and injection molding, it will lead to difficult alignment and excessive material loss, which will lead to increased costs. And other shortcomings, and the difficulty of the laser engraving process in the later stage also makes it impossible to manufacture products such as transparent patterns.

Table 2 below shows the characteristics and disadvantages of various known decoration techniques.

Next, the molded film 100A is brought into contact with the workpiece 200, and a pressing step is performed. Afterwards, a high-pressure vacuum forming step is performed on the formed film 100A, so that the formed film 100A is attached to the workpiece 200 . Finally, the remaining composite layer structure can be optionally removed by die cutting, laser cutting or water jet cutting. In short, in this embodiment, the molded film 100A can be closely adhered to the part of the outer surface 200a of the workpiece 200 by the out-of-mold decoration technology.

Referring back to FIG. 1 , after the decorative molding 10 is formed, step S140 is performed to perform a second curing step to increase the hardness of the composite layer structure 110 . In one embodiment, the second curing step may include a thermal curing step, an ultraviolet (UV) curing step, a combination thereof, or other suitable curing steps. In this embodiment, the first curing step is different from the second curing step. For example, the first curing step can be a thermal curing step and the second curing step can be a UV curing step; vice versa. In an alternative embodiment, when both the first curing step and the second curing step are thermal curing steps, the curing temperature of the second curing step may be higher than that of the first curing step. It is worth noting that the second curing step can make the protective material carry out a cross-linking reaction, so as to increase the hardness of the top surface 108 a of the optical hardening layer 108 , thereby improving the protective effect. That is to say, when the in-mold decoration technique or the out-of-mold decoration technique (ie, step S130 ) is performed, the optical hardening layer 108 is not fully cured yet has ductility, and is then completely attached to the outer surface 200 a of the workpiece 200 . During the second curing step (i.e. After step S140), the optical hardening layer 108 is completely cured and has a complete protective effect. In this embodiment, the hardness of the optical hardening layer 108 may have a gradient change. Specifically, the hardness of the optical hardening layer 108 may increase from the bottom surface 108b toward the top surface 108a. That is, the hardness of the top surface 108 a of the optical hardening layer 108 may be greater than the hardness of the bottom surface 108 b of the optical hardening layer 108 . In addition, the second curing step can also increase the hardness of the first decoration layer 104 and the second decoration layer 106 to facilitate the subsequent laser engraving process (that is, step S150 ).

Then, step S150 is performed to perform a laser engraving process to form the groove 105 in the composite layer structure 110 . As shown in FIG. 2A , the groove 105 may extend downward from the top surface 110 a of the composite layer structure 110 until the top surface 104 t of the first decoration layer 104 is exposed. But the present invention is not limited thereto, and in other embodiments, the grooves 105 may also have different depths. That is to say, the bottom surface 105bt of the groove 105 can be higher than or lower than the top surface 104t of the first decoration layer 104, or the bottom surface 105bt of the groove 105 can be higher than, equal to or lower than the top of the second decoration layer 106. Surface 106t. In addition, although FIG. 2A only depicts a single groove 105, the present invention is not limited thereto. In an alternative embodiment, the decorative molded article 10 may have multiple grooves to form various laser engraving patterns. Thereby increasing the visual experience of consumers.

Afterwards, step S160 is performed to form a protective layer 112A in the groove 105 . Specifically, the protection layer 112A can be formed by using a three-dimensional (3D) printing technique. In one embodiment, the 3D printing technology includes an aerosol jet printing process. The aerosol spray printing process uses an aerosol jet deposition head to form an external An annular propagating nozzle composed of an outer sheath flow and an inner aerosol-laden carrier flow. In the annular aerosol spraying process, an aerosol stream of the material to be deposited is focused and deposited on the surface to be formed. The above steps can be called maskless mesoscale material deposition (M3D), that is, it can be deposited without using a mask. In an alternative embodiment, the protective layer 112A can also be formed by using ink jet printing technology.

In this embodiment, as shown in FIG. 2A , the filling ink is filled into the groove 105 through the nozzle of the 3D printing device. In one embodiment, the filling ink can be similar to the above-mentioned third paint, which at least includes a uniformly mixed protective material, ink material and bonding material, and the content of the protective material in the filling ink can be higher than that of the first paint or The content of the protective material in the second paint. In addition, after the filling ink is filled into the groove 105 , an additional curing step may be performed, so that the protective material in the filling ink undergoes a cross-linking reaction, thereby increasing the hardness of the protective layer 112A. In this case, the protection layer 112A can partially protect the laser-engraved texture, that is, the first decoration layer 104 and the second decoration layer 106 exposed in the groove 105 from being damaged, so as to further enhance the protection effect of the composite layer structure 110 And increase the service life.

It is worth noting that the nozzle used in the 3D printing technology of this embodiment is small enough, so the filling ink can be accurately filled in the groove to form a protective layer locally, thereby protecting the texture after laser engraving. Compared with the general spraying technology that volatilizes a large amount of paint into the air, the use of 3D printing technology in this embodiment can effectively reduce material consumption and reduce manufacturing costs. In addition, the spray head of the general spraying technology is relatively large, which makes the spraying The coating is spotty and discontinuous, resulting in a rough and uneven finish. On the other hand, the 3D printing technology nozzle of this embodiment is small enough, it can completely fill the filling ink in the narrow groove and distribute it continuously on the surface of the object, so that the protective layer is more smooth and beautiful. In addition, the 3D printing technology of this embodiment can also perform partial color adjustment. That is to say, in this embodiment, protective layers of different colors can be filled in different groove positions according to customer requirements, so as to increase the visual experience of viewers.

In addition, although the protective layer 112A shown in FIG. 2A is only located in the groove 105 , that is, the top surface of the protective layer 112A is coplanar with the top surface 108 a of the optical hardening layer 108 , but the present invention is not limited thereto. In other embodiments, as shown in FIG. 2B , the protection layer 112B may also extend from the groove 105 and cover the top surface 108 a of the optical hardening layer 108 . The protection layer 112B can adjust the range or area of the extension part according to design requirements.

Referring back to FIG. 2A , the decorative molded article 10 can be disposed on the light source 300 to emit light of various colors through the protective layer 112A in the groove 105 . For example, the light source 300 may be a blue light, the protective layer 112A may be a white transparent material, and the second decoration layer 106 may be a wood grain layer. When the light source 300 is not turned on, the consumer can see the white transparent laser engraved pattern with the wood grain layer as the bottom from the viewing surface or the top surface 110a. On the other hand, when the light source 300 is turned on, the consumer can see the laser engraved pattern with blue light effect from the viewing surface or the top surface 110 a through the protective layer 112A in the groove 105 . In an embodiment, the light source 300 may include an LED point light source, an LED light bar, a mini LED, and the like. In addition, the protection layer 112A can also have various colors to combine with the light source 300 to produce different color mixing effects. For example, when the light source 300 is blue light and the protective layer 112A is a red light-transmitting material, when the light source 300 is turned on, consumers can The laser engraving pattern with purple light effect can be seen through the protective layer 112A in the groove 105 from the viewing surface or the top surface 110a. In an alternative embodiment, the protection layer 112A can also be made of a semi-transparent material or an opaque material.

In the conventional spraying technology, multiple spraying steps and multiple laser engraving steps are required to form a multi-color film. The disadvantages of this technology are: cumbersome manufacturing process, difficult processing, high cost and high degree of environmental pollution. In addition, in conventional decoration processes (such as IMD or OMD), multi-color thin films are usually formed by stencil printing. However, this technology will lead to disadvantages such as difficult alignment, low yield, excessive material consumption, and high cost after the client goes through processes such as blister forming, cutting, and injection molding. In addition, since the IMD film or the OMD film is relatively thin, it is not conducive to the laser engraving process. That is to say, even after laser engraving, the film after laser engraving will peel off or be damaged due to poor surface properties. Therefore, an additional protective coating needs to be formed to protect the film, which will increase the cost.

In order to solve the above problems, the inventive embodiment of the present invention forms an all-in-one coating on the base material and performs a curing step, thereby forming a composite layer structure with protection effect, color effect and bonding effect. The composite layer structure can form a molded film with better physical properties (such as higher hardness, better protection effect, etc.) after undergoing a blister molding process. In addition, compared with the conventional spraying technology or INS technology, the manufacturing steps of the composite layer structure created by the present invention are more simplified, and the manufacturing cost can also be effectively reduced. Therefore, the molded film of this embodiment is suitable for laser engraving process, and then forms various light-transmitting decorative moldings. In addition, this new creation further partially forms the protective layer 112A or 112B in the groove 105 to protect the laser-engraved texture from damaged, thereby improving the protection effect of the composite layer structure 110 and increasing the service life.

In addition, the traditional in-mold labeling (IML) technology is to perform screen printing on the back of the substrate (such as PC, PMMA, ABS, etc.) to form a 3-5-layer decorative layer, and then form 3-10 layers The adhesive layer can be attached to the workpiece. Compared with the conventional IML technology, the base material 102 of this embodiment will be melted due to high temperature and high pressure during the injection molding process, and then can be directly bonded to the part of the outer surface 200 a of the workpiece 200 . That is to say, compared with the conventional IML technology, the new creation does not need to form an additional bonding layer, which simplifies the manufacturing steps of the decorated molded product and reduces the manufacturing cost.

FIG. 3 is a schematic flowchart of a method for manufacturing a decorated molded article according to a second embodiment of the new creation. Fig. 4 is a schematic cross-sectional view of a decorated molded product according to the second embodiment of the new creation.

Please refer to FIG. 3 and FIG. 4 , the second embodiment of the new creation provides a manufacturing method S20 of a decorated molded product 20 as follows.

Next, step S104 is performed, forming the second paint on the first paint by coating, printing or 3D printing. Then, proceed to step S107, forming a fourth coating on the second coating by using a coating method, a printing method or a 3D printing method. In one embodiment, the fourth paint at least includes: a protective material, an ink material, and a bonding material mixed uniformly together. In addition, the coating method, printing method, protective material, ink material and laminating material have been described in detail in the above paragraphs, and will not be repeated here. It should be noted that the fourth paint is used to form the anti-shock adhesive layer 118 (As shown in Figure 4). In this embodiment, the content of the bonding material in the fourth paint can be higher than that of the bonding material in the first paint or the second paint, so as to increase the adhesion between the composite layer structure 120 and the subsequently formed workpiece 200 . As shown in FIG. 4 , the composite layer structure 120 includes a first decoration layer 104 , a second decoration layer 106 and an impact-proof adhesive layer 118 .

The impact-proof adhesive layer 118 can be disposed on the second decoration layer 106 such that the second decoration layer 106 is disposed between the first surface 102 a of the substrate 102 and the impact-proof adhesive layer 118 . In addition, in addition to the coating method, the anti-impact adhesive layer 118 can also be formed on the second decoration layer 106 by a coating method, an embossing method, a 3D printing method or a jet printing method. Compared with the ink layer or printing layer in the conventional INS, which needs to be matched with the bonding substrate process, and the conventional IML technology needs to form 3~10 layers of adhesive layers before it can be attached to the workpiece, the anti-impact adhesive layer of this embodiment 118 not only provides color effect, but also has high temperature resistance, protective effect and laminating effect, without the need to form an additional adhesive layer. That is to say, the novel creation can effectively simplify the manufacturing steps of the composite layer structure 120 , and provide the composite layer structure 120 with better high temperature resistance, better protection and bonding effects. Furthermore, compared with the conventional spraying technology, INS or IML technology, the manufacturing steps of the composite layer structure created by the present invention are more simplified, and the manufacturing cost can also be effectively reduced.

In one embodiment, the filling ink may be similar to the above-mentioned fourth paint, which at least includes a uniformly mixed protective material, ink material, and bonding material, and the content of the bonding material in the filling ink may be higher than that of the first coating. The content of the bonding material in the paint or the second paint. In addition, after filling the filling ink into the groove 105 , an additional curing step may be performed to increase the adhesion between the composite layer structure 120 and the subsequently formed workpiece 200 . In this case, the protective layer 212 can partially protect the laser-engraved texture, that is, the first decorative layer 104 and the second decorative layer 106 exposed in the groove 105 from being damaged, so as to further enhance the protective effect of the composite layer structure 120 And increase the service life. In an alternative embodiment, the protection layer 212 can also be formed by jet printing technology.

In an alternative embodiment, 3D printing technology can be used to backfill the protective layer into the laser-engraved light-transmitting area (such as the groove 105), and 3D printing technology can also make different effects in the non-laser-engraved light-transmitting area, such as forming a logo (logo) or gradient and other similar opaque film effects. Afterwards, an additional optically hardened layer is selectively formed by lamination, embossing, 3D printing or jet printing as appropriate.

Afterwards, step S170 is performed to perform in-mold decoration technology or out-of-mold decoration technology, so that the forming film 100B is attached to the inner surface 200b of the workpiece 200 to form a A decorative molded product 20 is formed, as shown in FIG. 4 .
