Embodiment 1
[0035] Such as Figure 1 to Figure 4A method of manufacturing a coated lens provided with a pattern is shown, and the manufacturing method includes the following steps:
[0036] 1) Make the pad printing steel plate: engrave the pattern to be printed on the pad printing steel plate. According to the needs of the coating pattern, the engraved pattern is inscribed, and the depth of the pattern engraved on the steel plate is 20 μm.
[0037] 2) Pad printing: Use a pad printing machine to apply ink on the steel plate, scrape off the ink on the surface of the steel plate with a scraper, press the rubber head onto the pad printing steel plate, and transfer the ink on the pad printing steel plate to the surface of the rubber head. Then use the rubber head to press the ink-coated rubber head to the surface of the lens, so that the pattern is transferred to the surface of the lens, so that the ink on the steel plate can be transferred to the lens as figure 2 shown. In order to print i...
Embodiment 2
[0063] Such as figure 1 A method for manufacturing a coated lens provided with a pattern is shown, and the method includes the following steps: Step 1) Same as Example 1, the depth of the pattern engraved on the steel plate is 25μ.
[0064] Step 2) is the same as in Example 1, but the components of the ink include resin, pigment, solvent, additive and release agent, in percentage by mass: 21% for resin, 12% for pigment, 63% for solvent, and 2% for additive %, release agent 1%, aluminum carbonate 1%. The resin is an alkyd resin, the additive is a plasticizer, and the plasticizer is tricresyl phosphate, and the release agent includes silicone oil, surfactant, LPG propellant and solvent. Using the combination of the above materials, an ideal fixation effect can be achieved. Using the above ink can make the pad printing ink have good fluidity, so that the pad printing pad will not dry before dipping the ink; when the ink is dipped by the pad, the ink can be transferred to the pa...
Embodiment 3
[0077] Such as figure 1 A method for manufacturing a coated lens provided with a pattern is shown, and the method includes the following steps: Step 1) Same as Example 1, the depth of the pattern engraved on the steel plate is 22 μm.
[0078] Step 2) is the same as in Example 1, but the components of the ink include resin, pigment, solvent, additive and release agent, in percentage by mass: resin is 25%, pigment is 15%, solvent is 54%, additive is 2 %, release agent 2%, aluminum carbonate 2%, resin is polyurethane alkyd resin, described additive is plasticizer, and plasticizer is set to triphenyl phosphate, and described release agent includes silicone oil, surfactant Agents, LPG propellants and solvents. Using the ink with the above ratio, the pattern will not be incomplete, and the ink will not be blurred due to the flow, and the pad printing effect is good.
[0079] 3) Drying: Dry the ink pattern printed on the lens; put the lens in an oven at 50 ℃ to dry the ink, and set...
