Description
Technical Field
The invention relates to the technical field of nano-imprinting, in particular to a method for preparing a winding drum nano-imprinting roller by ultraviolet curing resin with the depth of 3-10 mu m.
Background
The nano-imprinting technology is a novel micro-nano processing technology. The technology achieves the copying of the micro-nano structure with ultrahigh resolution by means of mechanical transfer.
Currently, flat pressing or roller pressing is generally adopted when ultraviolet curing nano-pressing is carried out to copy a microstructure. Wherein the flat pressing speed is slow and the efficiency is low, and continuous microstructures cannot be prepared; the existing roller impression generally adopts a metal nickel master plate to be pasted on a roller for impression, and although the efficiency is higher, a continuous microstructure can not be prepared.
Disclosure of Invention
In order to solve the problems of continuous pattern seamless nano-imprinting and metal plate seam glue stacking in the traditional imprinting mode, the application provides a method for preparing a winding drum nano-imprinting roller by using ultraviolet curing resin.
The technical scheme adopted by the invention is as follows:
a method for preparing a winding drum nanometer embossing roller by ultraviolet curing resin is characterized by comprising the following steps:
s1, preparing a micro-nano structure PET resin master plate;
s2, carrying out laser roughening treatment on the surface of the metal plate roller;
s3, coating epoxy acrylic resin on the metal printing roller to prepare a micro-nano structure epoxy acrylic resin printing roller;
and S4, irradiating the curing coating by an ultraviolet lamp for curing and carrying out nanoimprint production.
Further, the method for preparing the micro-nano structure PET resin master in step S1 includes copying the nano microstructure on the metal master roller to the PET resin film through the ultraviolet curing coating, and irradiating the PET resin master with an ultraviolet lamp for a long time to make the coating fully cure and crystallize on the surface.
Further, the process of copying the nano-microstructure to the PET resin film comprises copying the nano-microstructure on the metal nickel master to the PET resin film with the thickness of 100-250 μm through ultraviolet curing coating.
Furthermore, when the micro-nano structure epoxy acrylic resin plate roller is prepared, the light shielding part and a target on the PET resin master plate need to be aligned according to the positioning mark, and the light shielding part and the PET resin master plate are tightly attached by using the invisible film adhesive tape.
Further, the shading component adopts a shading cover.
Further, when the surface of the metal plate roller is subjected to laser roughening treatment, the surface of the metal master plate roller is roughened by engraving the micro holes through laser so as to increase the bonding force between the epoxy acrylic resin coating layer and the metal.
Compared with the prior art, the invention has the beneficial effects that: the invention can realize lap joint at the joint of the circulating patterns, can improve the printing durability of the printing roller and can solve the problem of glue accumulation caused by the roll gap difference of the metal master plate.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 2 is a diagram of the operating state of the method of the present invention.
Detailed Description
As shown in fig. 1 and 2, a method for preparing a web nanoimprint lithography roller from an ultraviolet curable resin includes the steps of:
s1, preparing a micro-nano structure PET resin master plate;
specifically, in this step, the nano-microstructure on the metallic nickel master 1 needs to be copied onto the PET resin film 2 with a thickness of 100 μm to 250 μm by using an ultraviolet curing coating to form a PET resin master, and the PET resin master is irradiated by an ultraviolet lamp for a long time to fully cure the coating and crystallize the surface.
S2, carrying out laser roughening treatment on the surface of the metal plate roller;
in the step, the surface of the metal nickel master plate needs to be roughened by engraving micro holes through laser so as to increase the binding force between the epoxy acrylic resin pattern layer and the metal and improve the printing resistance of the printing roller.
S3, coating epoxy acrylic resin on the metal printing roller to prepare a micro-nano structure epoxy acrylic resin printing roller;
when the step is implemented, the light shield 3 and the target on the PET resin mother plate can be aligned according to the positioning mark, and the light shield 3 and the PET resin mother plate are tightly attached by using the invisible film adhesive tape. The purpose of the light shield 3 is to shield the redundant structural layers during the ultraviolet curing process according to the calculated circumference or cycle of the metal plate roller, and only the required continuous microstructure is left on the cured resin coating on the surface of the metal plate roller.
S4, curing the curing coating by ultraviolet lamp irradiation and carrying out nanoimprint production;
in the step, in the curing process, the curing coating is irradiated by the ultraviolet lamp 4 for curing, the epoxy acrylic resin curing coating can be adopted, the used epoxy acrylic resin curing coating also needs to be adjusted according to the metal bonding force and needs to have good metal bonding force and demolding performance, and the imprint production method in the step can be carried out according to a conventional production mode.
The method uses the epoxy acrylic resin plate roller to replace the original nickel metal plate, and because the nano microstructure on the periphery of the plate is formed by curing the coating, the lapping can be realized at the joint of the circulating pattern, the printing resistance of the plate roller can be improved, and the problem of glue piling caused by the gap fall of the metal plate is solved. Particularly in double-sided micro-nano structure imprinting with the microstructure on two sides needing accurate alignment, the epoxy acrylic resin printing roller prepared by the invention has the advantage over an imprinting mode using a metal nickel plate in the aspect of circumferential error control because the thickness of the glue layer is controllable, so that the imprinting positioning of the micro-nano structure on two sides is more accurate.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
