Abstract
Description
Technical area
[0001] The utility model relates to the field of card production, in particular to a coated PVC color card base. State of the art
[0002] The background color of PVC color cards is the base color of each card. The color is dark, and the visual effect of directly printing different color patterns and texts is poor. Before printing the pattern and text, a white layer (called the printing layer) must be applied to the color card base as a background to give the card pattern and text a good visual aesthetic. The original manufacturing process of the PVC color card base printing layer is completed by screen printing or coating printing.
[0003] However, screen printing has low work efficiency. Although coating printing has solved the problem of work efficiency, it still has the following shortcomings: 1. The opacity is unstable; 2. The whiteness controllability is poor; 3. The peel strength is low. Therefore, a solution to further improve the performance of color card bases is needed. Content of the utility model
[0004] The object of this utility model is to provide a coated PVC color card base to solve the technical problem of insufficient application performance of the color card base.
[0005] In order to solve the above-mentioned technical problems, the present utility model provides a coated PVC color card base comprising: a sequentially laminated color card base layer and a PVC printing layer; the thickness of the PVC printing layer is 0.02 to 0.04 mm.
[0006] The thickness of the card base layer is 0.4-0.6 mm.
[0007] Furthermore, the peel strength of the PVC printing layer is not less than 11.4N / cm.
[0008] Furthermore, the whiteness of the red card base coating of the coated PVC color card base is not less than 96.89.
[0009] Furthermore, the whiteness of the blue card base coating of the coated PVC color card base is not less than 97.89.
[0010] The advantageous effect of the utility model is that the coated PVC color card base of the utility model eliminates the original cumbersome processes of screen printing and coating printing. By directly coating the PVC printing layer on the color card base layer to form a composite material, it significantly improves the production efficiency of the card factory and reduces costs. The improved structure features stable and controllable whiteness, good coverage, high bond strength of the printing layer, and clear offset printing ink, improving the quality of the card factory's products. Description of the illustrations
[0011] The present utility model will be discussed in more detail below using specific embodiments with reference to the attached illustrations.
[0012] Fig.is a schematic structural diagram of the coated PVC color card base.
[0013] In the figure: Card base layer 1, PVC printing layer 2. Detailed embodiments
[0014] The embodiments of the present utility model are described in detail below with reference to the attached figures. These figures are simplified schematic representations intended to merely schematically illustrate the basic structure of the present utility model. Therefore, only the structures related to the present utility model are shown.
[0015] As in Fig. As shown, this embodiment provides coated PVC color card base including: a sequentially laminated color card base layer, and a PVC printing layer, wherein the thickness of the PVC printing layer is 0.02 to 0.04 mm.
[0016] Specifically, the thickness of the existing screen printing layer is 0.20-0.22 mm, and the thickness of the printing layer of the coating process is 0.005-0.01 mm. Although the thickness of the PVC printing layer in this embodiment is 0.02-0.04 mm thicker than the printing layer of the coating printing process, since the one structural layer of the screen printing process is omitted, the thickness of the card base is greatly reduced.
[0017] In this embodiment, the thickness of the card base layer is from 0.4 to 0.6 mm.
[0018] In this embodiment, in particular, the peel strength of the PVC printing layer is not less than 11.4 N / cm, where the industry standard requirement is ≥ 6 N / cm, and the peel strength of the conventional screen printing layer is 6.6-7.5 N / cm. The test standard: GB / T 2792-2014, 90° peel; In this embodiment, the peel strength is significantly improved by directly laminating the PVC printing layer to the card base layer in one step of the casting process.
[0019] In this embodiment, the whiteness of the red card base coating of the coated PVC color card base is not less than 96.89.
[0020] In this embodiment, the whiteness of the blue card base coating of the coated PVC color card base is not less than 97.89.
[0021] In particular, the covering performance and whiteness of different card bases are compared and the performance is as follows. Embodiments Whiteness Layering of the red card base 96, 89 Layering the blue map base 97, 89 Layering the red card base of the screen print 82, 06 Layering the red card base of the coating print 79, 34, 88, 69 Layering the blue card base of the coating print 93, 92
[0022] It can be seen that the whiteness of the red card base and the blue card base is significantly improved by the structure of this embodiment.
[0023] In summary, this embodiment provides a one-time co-extruded coated PVC color card base by casting. It eliminates the original cumbersome processes of screen printing and coating printing by directly applying the PVC printing layer to the color card base layer to form a composite material, significantly improving the production efficiency of the card factory. At the same time, costs are reduced. The improved structure exhibits stable and controllable whiteness, good hiding power, high bond strength of the printing layer, and clear offset printing ink, improving the quality of the card factory's products.
