Method for preparing multi-channel 3D nano texture mold

Abstract

A method for preparing a multi-channel 3D nano texture mold comprises the steps of: coating photoresist on a PET photoetching material, and then entering a stainless steel dust-free furnace for dryingfor standby; arranging a mask pattern plate on the raw rubber surface of the PET photoetching material, vacuuming for photoetching, taking out the mask pattern plate after the photoetching is completed, putting the prepared developer into a cleaning box, putting the photoetching-finished PET photoetching material into the cleaning box for cleaning, displaying the pattern on the PET photoetching material, dehydrating and spinning to obtain a first texture layer; then, performing second texture layer photoetching process which is similar to the first layer, realizing second texture processing superposition to obtain the multi-channel 3D nano-texture mold. The method has the advantages of simple manufacturing process, low cost, reusability, multi-texture superposition, better texture rendering effect and improved working efficiency.

Description

technical field [0001] The invention relates to the technical field of mold preparation, in particular to a method for preparing a multi-channel 3D nano-texture mold. Background technique [0002] With the development of science and technology and the improvement of people's appreciation level, the electronics industry continues to grow and develop. The appearance of electronic products, especially portable devices such as mobile phones and notebooks, is becoming more and more refined and complex. Fine grain decorations such as orange peel grain, wood grain, imitation carbon fiber grain, and CD grain are becoming more and more popular, and all of them have been practically applied. With the continuous expansion of appearance decoration, the molds for banknote appearance decoration are increasingly demanding precision. At present, machining technology is mostly used for mold processing, including CNC (computer numerical control, computer numerical control machine tool), wire...

Problems solved by technology

This solution is mainly aimed at paper drawings that can be easily removed from the master. One drawing can only obtain one sample and cannot be reused; and in order to copy the drawing clearly, the coating thickness must be uniform, so the requirements for equipment and precision are also very important. At the same time, the pattern on the existing silica gel sheet is generally a single texture, and multiple patterns cannot be set on the same silica gel sheet. Therefore, it is necessary to find a more ideal method that can overcome the disadvantages of the prior art. For the above deficiencies, a technology to obtain better texture effects and multi-layer texture overlay effects
