TW455543B - Method for producing transparent piece with porous water-discharging properties and transparent piece therefrom - Google Patents

Abstract

The present invention relates to a method for producing a transparent piece with porous water-discharging properties and a transparent piece therefrom. The method comprises sequentially applying a fiber layer (or a fiber imitating layer), an adhesive layer, and a release paper on a substrate, in which the sequence of the fiber layer and the adhesive layer can be interchanged, or the two faces of the fiber layer can both have an adhesive layer; performing a punching operation on the composite material to form a semi-product of a lens; printing an ink on the substrate to complete the production of a color lens with water-discharging properties. The printing process comprises a direct printing, a thermal transfer printing, a thermal press printing, a computer spray-painting, etc. If a direct printing is carried out, the punched release paper needs to be removed, followed by laminating a complete release paper, prior to printing. If a computer spray-painting is used, the bottom of the semi-product of the lens needs to be installed with an absorption layer. If a thermal transfer printing or a thermal press printing is used, a transfer printing film needs to be used in order to transfer the ink of a transfer printing film to the substrate so that the used transfer printing film can be used with the un-punched semi-product of the lens (i.e. formed by a substrate layer, an adhesive layer, a release paper, without a fiber layer). After a second thermal transfer printing or a thermal press printing, the remaining ink on the transfer printing film is transferred to the substrate to complete a color lens without water-discharging properties.

Description

455543 V. Description of the invention (1) [Industrial use range] The present invention relates to a perspective sheet manufacturing method and a perspective sheet structure that have holes on the base layer to create a new vision. This perspective sheet can produce beautiful text or patterns on the outside. The interior can clearly see the outside scene, so it can be used in car glass, car advertisements, building glass curtains, and transparent PC board, transparent PC glass board, PC sun visor, etc. [Background of the Invention] The habit of using multi-layer screen printing on transparent substrates (such as transparent film, glass, acrylic and other transparent materials) often fails to achieve excellent quality due to inaccurate overprinting. In view of this, an advanced person has invented a new manufacturing method, such as Annex I Announcement No. 2 6 2 4 3 5 "Method for Manufacturing a New Visual Sensitive Perspective Film", which is a method of screen printing using transparent ink 2 [可(See the first picture.) It is coated on the transparent base layer 1 through the mesh 81 of the screen 8. The transparent ink 2 is similar to the ink for scratch lottery. When the screen 8 is removed, the transparent ink 2 will produce a plurality of depressions. Into the small hole 2 1 [as shown in the second figure]. After drying, the first layer of dark ink 3 1 can be coated on the transparent ink layer 2 [as shown in the third figure], and then the second layer of light ink 3 2 can be applied after being air-dried, and then dried After that, the third layer of color pattern ink 3 3 is applied; wherein, the color ink 33 is printed on a pre-designed pattern screen. After drying, at least two layers of different color ink layers (ie, ink dots 3) will be deposited in the small hole 21, and the transparent ink layer 2 can be finally peeled off with adhesive tape and rinsed with a washing machine, but in a transparent base layer 1 will easily leave ink dots 3 and some residual ink 2 2

455543 V. Description of the invention (2) [as shown in the fourth figure]. A transparent adhesive layer 4 and a tearable release paper 5 can be added to the bottom surface of the transparent base layer 1 to form a finished color see-through sheet 6. Attachment 2 is the hooking bulletin No. 3 5 3 ϋ 50 "Method for manufacturing transparent patches". The manufacturing process and method in this case are the same as those in Annex 1. The only difference is that the printing order of the three inks is the first. Layer of color ink (pattern coating), the second layer of light ink (background overlay), and the third layer of dark ink (bottom overlay). Since the technical means and principles of the two cases are the same, we will not repeat them here. [Problem of the practice] The biggest disadvantage of the practice is that the transparent ink 2 is printed on the transparent base layer 1 by screen printing through the screen plate 8. After the multi-color ink screen printing is completed, the transparent ink 2 layer must be peeled off, but Part of the transparent ink 2 is rigidly fixed on the transparent base layer 1, and the ink and the ink have considerable adhesiveness, so it is not easy to tear off, and there is a residual ink 2 2 on the transparent base layer 1 (as shown in the fourth figure) (Shown), in order to meet the quality requirements, it is necessary to remove the residual ink 2 2 with a tape stripper and a washing machine, so it will increase the trouble of the manufacturer and delay the working hours. If it is not completely removed, it will leave unsightly ink stains on the transparent base layer 1, which will greatly reduce the visual effect. In addition, when tearing off or rinsing the transparent ink 2 on the glass material, it is easy to peel off the ink dot 3-so it cannot be made on the glass material. [Previous case creation of the inventor]

45C V. Description of the Invention (3) Several types of perspective film production systems were developed before the application was filed: 1, Perspective Film Production Method No. 87109210 Γ2, No. 87112920 "Method of Printing Perspective Film 3", No. 8 8 1 0 No. 0 9 2 7 "Although the inventor had a problem to be solved before, the video film was stuck on the glass surface and water droplets accumulated on the rear surface, so that the bright dots could see the external scene beads completely evaporate. The glass curtain building or large-scale building needs to be developed by oneself. The inventor has further improved the practice, and has made a method. He has applied for a patent to the hook office, and the multi-color overprinting makes the point to point 100% accurate (application date: June 87 10th). 100% accurate set between non-dot and non-dot "(application date: August 05, 1987). Dot or non-screen by transfer or embossing "(application date: January 21, 88). The three inventions will be superior to the formula in the manufacturing method, but the problem is also the one that the formula has never been solved, that is, it will be transparent when the rain or water is washed. The penetration of the film causes severely affected sight. If water is to disappear after a long period of time, the user can wipe it with a rag to remove the water droplets, but it is helpless for glass doors and windows. [Technical means of the present invention] The manufacturing method of the drainage see-through sheet of the present invention is, from top to bottom, a fiber layer (or fiber-like layer), an adhesive layer, and a release paper on a base layer, wherein the fiber layer and the adhesive layer The order of the glue layers is interchangeable or the upper and lower sides of the fiber layer are both adhesive layers. The aforementioned structural layer is processed into a semi-finished product through punching, and then the color (or multi-layer) ink on the transfer film is transferred by thermal transfer technology.

Page 7 V. Description of the invention (4) Printed on the semi-finished perspective film, which completes the production of colored "drainage" perspective films. Secondly, the bottom surface of the semi-finished perspective film can also be attached with an absorbing layer. The color ink is sprayed on the semi-finished product of the see-through sheet. After the spraying is completed, the absorption layer is torn off to complete the production of the colored "drainage" see-through sheet. In addition, it can also tear off the release paper after punching the semi-finished product of the see-through film, and paste another layer of un-punched release paper, and then print the color ink on the semi-finished product of the see-through film by direct printing technology. "The production of see-through films. In addition, the semi-finished product of the see-through sheet can be combined with the transfer film, placed on the lower printing table, and then hot-pressed by the upper printing table, so that the multi-layer ink of the transfer film is printed on the base layer to complete the color "drainage" perspective. Film making. In addition, the aforementioned thermal transfer or thermal embossed transfer film can be combined with a semi-finished "perforated" see-through sheet (consisting of a base layer, an adhesive layer, and a release paper, but without a fiber layer), and applied separately. The second thermal transfer or thermal embossing is used to print the multilayer ink on the transfer film to the base layer, so that the production of the color "non-drainage" see-through sheet is completed. The aforementioned medium-colored "drainage" see-through sheet structure is composed of a transparent base layer, a fiber layer (or fiber-like layer), an adhesive layer, and a release paper. The see-through sheet is densely covered with a plurality of hollow small holes, and the other fiber layer is Netted dense water-absorbent fiber threads are interwoven, and the broken surfaces of multiple fiber threads are exposed on the inner wall of each hollow pinhole.

455543 V. Description of the invention (5) [Function] The inside of the drainage see-through sheet contains a layer of water-absorbing fiber. The fiber layer can absorb the water droplets left on the see-through sheet through the small holes of the see-through sheet. The conductive effect quickly drains water. Using thermal transfer, hot embossing or color printing, direct printing technology, ink can be printed on the transparent base layer of the semi-finished film. In the thermal transfer and thermal imprint technology, after the first transfer of the transfer film and the "water-repellent" see-through sheet semi-finished product, some of the ink can be transferred to the transparent substrate and transferred to the small holes. As the ink is not in contact with the transparent base layer, it remains on the transfer film. The previously used transfer film and semi-finished "non-drainage" see-through sheet were subjected to a second thermal transfer, and all the ink (in the form of dots) on the transfer film was transferred to the transparent base layer. [Embodiment] The detailed description is as follows according to the embodiment shown in the figure: Please refer to the fifth figure, which is a flowchart of the production of the color perspective film of the present invention. The figure discloses that the base layer 10 is sequentially connected with the fiber layer 20 and the adhesive layer. 30. Release paper 40 is stacked into a composite body 50; wherein the order of the fiber layer 20 and the viscose layer 30 is interchangeable, or the fiber layer 20 is the viscose layer 30 before and after, and the fiber Layer 20 will fuse with adhesive layer 30. Please refer to the seventh figure. Figure 10 reveals that the base layer 10 is sequentially composed of the fiber layer 20 (or the fiber-like layer), the adhesive layer 30, and the release paper 40 (the peeling layer) into a multi-layered perspective sheet semi-finished product 50 ( As shown in Figure 28), the semi-finished product 50 becomes a "draining" see-through sheet semi-finished product 5 2 after being punched 5 1. At this time,

Page 9 455543 V. Description of the invention (6) There are many hollow small holes 5 2 1 (such as the ninth figure) on the entire surface. The shape of the small holes can be various, for example: round, square, triangle, oval, six Angle and so on. In addition, the base layer 10 may be made of a material such as PVC film, glass, acrylic film, and road cymbal film. The fiber layer 20 (or imitation fiber layer) [see Figure 9A] is formed by interweaving a number of crosswise and densely packed absorbent fiber threads 2 1 (such as cotton yarn); A plurality of hollow small holes 5 2 1, and a hole surface of each small hole 5 2 1 exposes a plurality of fiber thread 21 fracture surfaces, and the fracture surfaces are in contact with the outside world to facilitate water absorption. Please refer to the sixth figure. The printing process of the "drainage" color see-through film can be divided into three ways. The first method is to complete the semi-finished see-through film 5 2 by direct printing. Form paper 40 (refer to the tenth picture), and then apply a complete release paper 41 (see the eleventh picture), and then use direct printing 7 1 to print the color ink (YMCK) on the base layer. During the printing process, the semi-finished product 52 is placed on the suction table. Since the release paper 41 is a complete paper, it will be attached by vacuum suction on the suction table, and then printed by gravure or screen printing. Color ink can be printed on the base layer 10 to complete the color drainage see-through sheet 100 (see Figure 12). In the color drainage see-through sheet, the base layer 10 is light (ie, the background color, such as white), the adhesive layer 30 is dark (ie, the background color, such as black), and the color ink 200 is a single color or system. Multiple colors (ie pattern colors). The second printing process is a computer spraying process, which involves adding an absorbent layer 60 (see Figure 13) to the bottom surface of the semi-finished product 52 of the perforated perspective sheet, and then printing the ink through computer color spraying. To the see-through half

Page 10 455543 V. Description of the invention (7) The finished product 5 2 and the ink sprayed into the small holes 5 2 1 are absorbed by the absorption layer 60, and when the absorption layer 60 is torn off (fourteenth figure) That is, a color drainage see-through film 100 is completed, wherein the base layer 10 is light (ie, background color, such as white), the adhesive layer 30 is dark (ie, background color, such as black), and color ink 2 0 0 is single or multi-color (ie pattern color). The third printing process can refer to the fifteenth figure of the thermal transfer printing process, which involves passing the semi-finished perspective film 5 2 and the transfer film 9 1 (plastic materials such as PVC or OPP) through two printing rollers 9 2 1, 9 2 2 After thermal transfer printing, part of the color ink 2 0 0 on the transfer film 9 1 was transferred to the base layer 10 of the semi-finished semi-finished film. Because the hollow small hole 52 1 was not the same as the color ink of the transfer ink 9 1 Contact, so the non-contact color ink remains on the transfer film 91, and after the printing is completed, it becomes a color drainage see-through sheet 100 and a transfer film residue 300. In the drainage see-through sheet, the base layer 10 is light-colored (for a background color, such as white), the adhesive layer 30 is dark-colored (for a background color, such as black), and the color ink 200 is single-colored or multi-colored. (For pattern color). Before using the above-mentioned drainage see-through sheet 100, the release paper 40 (or 41) must be peeled off, and then affixed to the glass surface (or transparent PC board, transparent PC glass board, PC by the adhesive layer 30). Sun visor, etc.). The front and back surfaces of the drainage see-through film 100 are different patterns, as shown in Figures 16 and 17. In its application, the sixteenth figure is the front side of the drainage see-through sheet 100, which reveals that the drainage see-through sheet 100 has a plurality of hollow holes 5 2 1 and the light-colored base layer 10 (such as gray, white, etc.) is visible on the surface. ) Color ink 2 0 0 is attached, so if the drainage see-through sheet 1 0 0 0 is affixed to the surface of the glass, a picture or text can be presented on the front when viewed from outside, so it can reach advertising

45 55 43 V. Description of invention ¢ 8) and artistic appreciation effect. The seventeenth figure is a rear view of the drainage see-through sheet 100, which reveals that the drainage see-through sheet 100 has a plurality of hollow holes 5 2 1 and a dark adhesive layer 3 0 (such as black is visible on the surface). , Coffee color), so when the drainage see-through film 100 is attached to the glass surface, the back can be viewed from the inside, and the outside scene can be clearly seen through the hollow small hole 5 2 1. Secondly, because the base layer 10 and the adhesive layer 30 are opaque, and the opacity of the color ink 200 is added, the drainage see-through sheet 100 can become a shading and heat-insulating see-through sheet. The base layer 10 and the adhesive layer 30 are transparent layers. The aforementioned printing process must be completely changed, and it can only be applied to hot stamping and thermal transfer. Among them, the hot stamping process is shown in Figure 18, The semi-finished product 52 for the see-through film is placed on the lower printing plate 6 0 in cooperation with the transfer film 80. The transfer film 80 has multiple layers of ink 2 0 4 (color, dark, light), and passes through the upper printing plate 6 After the hot pressing of 01, a part of the multilayer ink of the transfer film 80 was transferred onto the base layer 10 to complete the production of a color "drainage" see-through sheet 7 0 0 (as shown in Fig. 19). The process of thermal transfer is shown in Figure 20, and compared with Figure 15, the only difference is that the ink on the transfer film 80 is a multi-layer ink, not a single-layer color ink. In the final colored drainage see-through sheet 7 0 0 (see figure 19), the base layer 10 is transparent, followed by dark ink 2 0 1 (ground color) and light ink 2 0 2 (background color). ), Color ink 2 0 3 (pattern color). Due to the printing method of the transparent base layer 10 and the creator's previous case No. 8 8 1 0 9 2 7 "Dotted or imprinted by transfer or imprint method

Page 12 45 55 4 3 V. Description of the invention (9) The method of making the see-through film of the dots is the same, so the printing process will not be repeated here. The front and back views of the drainage see-through sheet 700 are shown in Figures 16 and 17. However, the above-mentioned transfer film remaining material after thermal embossing or thermal transfer 3 0 0 can be used for the second thermal embossing or thermal transfer with the semi-finished "non-drainage" see-through sheet. Here we only use thermal transfer It is further shown that this can be referred to the first image, which reveals that the non-drainage see-through sheet 8 0 0 is composed of a transparent base layer 8 0 1, an adhesive layer 8 0 2, and a release paper 8 0 3 and has not been punched. And there is no fiber layer (fiber layer) combination inside; when the second thermal transfer is performed with the transfer film residue 300, the remaining multilayer ink on the transfer film residue 300 (2 0 1 ~ 2 0 3) All transferred to the transparent base layer 10 of the non-drainage see-through sheet 8 0 0, and finally become the "non-drained" see-through sheet finished product and transfer film 3 0 1 (waste), The finished product of the perspective film is a point-to-point perspective film (the same as the finished perspective film made by the creator's previous case No. 8 1 0 9 2 10 patent case). In the above, the transfer film is thermally transferred twice, the first time is transferred to the drainage see-through sheet 700, and the second time is transferred to the non-drainage see-through sheet 800, and then the transfer is performed. The multilayer inks on the film surface are all used, so no material is wasted. The positive and negative sides of the undrained see-through sheet 800 are opposite to the aforementioned sixteenth and seventeenth pictures. This can be seen in the second and third pictures. The dots disclosed in the second picture are not hollow. Small holes, but with halftone dots of light-colored ink 202, and some halftone dots of light-colored ink 202 have color inks 2 03, and the dots are surrounded by a transparent base layer 801; the back of the see-through sheet is shown in Figure 23 The dots are dark ink 2 0 1 dots, and the dots are surrounded by a transparent base layer

Page 13 455543 V. Description of the invention (ίο) 8 Ο 1 Because it has no hollow pinholes, it is a transparent film with no drainage function. The twenty-fourth figure is a schematic diagram of the use of the "water-free water-based" see-through sheet. The figure reveals that the non-drainage see-through sheet 8 0 0 is torn off the release paper 8 0 3 and then fixed to the glass 5 0 by an adhesive layer 8 0 2. On the 0 surface, after rain or car washing, the water droplets 4 0 0 will remain on the non-drainage see-through sheet 8 0 0 without moving. This is because the plastic material of the transparent base layer 10 easily causes water to generate cohesion. The water droplets are formed on the surface of the see-through sheet 800, so when the user looks from the room to the outside, the transparent part 804 is covered by the water droplets 400, which seriously affects the sight. Evaporation needs to wait for several hours to air dry before returning to normal. Since the non-drainage fluoroscopy lens 800 and the conventional fluoroscopy film are not drainage, it is easy to produce blurred vision after rain. The twenty-fifth figure is a schematic diagram of automatic drainage of the "drainage" see-through sheet of the present invention. The figure reveals that after the rainy or water-washing sheet 100 has water droplets 4 0 0 temporarily stayed in the small holes 5 In 21, the fiber thread 2 1 in the fiber layer 20 can immediately absorb the water droplets in the small holes, and drain the excess water to the lower side to drain, so that the drainage see-through sheet 1 0 0 and glass The water on the 500 surface can be completely removed in a short period of time. As a result, the user's vision will not be affected when viewing from indoor to outdoor. [Effects] 1. After the rainwater is wet, the drainage colored see-through film can automatically drain and remove the water droplets accumulated on the surface without affecting the sight of the user. 2, the drainage color see-through film from the front (outside) shows a picture
