preparation example Construction

[0042] The third aspect of the present invention provides a method for preparing the transfer curing glue of the present invention, the method comprising:

[0043] (1) Stir and mix the components of the UV-curable adhesive composition of the present invention, and discharge air bubbles to prepare UV-curable adhesive;

[0044] (2) Curing the UV-curable glue solution by exposing it to UV light.

[0045] In the present invention, the UV-curable glue can be prepared by placing in a vacuum at 10-40° C. (for example, 25° C.) for 2-4 hours to discharge air bubbles. In addition, the vacuum may be in a state of an absolute pressure of 0.01-0.05 MPa.

[0046] In addition, in step (2), the exposure time may be 5-10s, for example.

[0047] The present invention also provides an application of the ultraviolet light-curable adhesive composition of the present invention in the fine pattern transfer process. It can be that the ultraviolet curable glue solution obtained by mixing the ultrav...

Abstract

The invention relates to the field of fine pattern transfer glue, and discloses an ultraviolet curing glue composition, a transfer curing glue and a preparation method. The UV curable adhesive composition contains: 40-80% by weight polyurethane acrylic acid, 5-15% by weight silicone resin, 3-15% by weight hyperbranched polyester acrylic acid, and 10-30% by weight reactive diluent , 3‑8% by weight photoinitiator and 0‑1% by weight optional additives. The ultraviolet curable adhesive composition of the present invention can be used for fine pattern transfer. The formed transfer cured adhesive has suitable surface energy, is easy to peel off from the mold, and leaves no residual glue on the mold.

Description

technical field [0001] The invention relates to the field of fine pattern transfer printing adhesives, in particular to an ultraviolet light curing adhesive composition, a transfer printing curing adhesive and a preparation method. Background technique [0002] In recent years, a variety of precise textures, laser textures, metal textures, frosted effects, and embossed effects have been produced through ultraviolet lithography to produce micro-nano structure molds and then transferred to PET films, and then PET films or plastic shells are pasted on the back of the mobile phone glass The industry pays more and more attention to the dazzling optical effect obtained by injection molding after hot pressing of PET film. This effect gives people a novel aesthetic feeling, which is incomparable to ordinary screen printing. [0003] The fineness of the transfer pattern is required to be high, most of which are at the micro-nano level, so the transfer is difficult. At present, micro...
