Abstract

The invention belongs to the technical field of glue and in particular relates to ultraviolet curing glue and a preparation method thereof. The ultraviolet curing glue comprises 50-75 percent of oligomer, 0-13 percent of single functional group active diluent, 20-35 percent of multi-functional group active diluent and 1-5 percent of photoinitiator. The oligomer is aliphatic urethane acrylate resin with the functionality of 2-4; the single functional group active diluent is selected from IBOA, IBOMA, beta-CEA and THFA); the multi-functional group active diluent is selected from HDDA, TPGDA andTMPTA; and the photoinitiator is selected from 1-hydroxyl-cyclohexylbenzophenone and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide. The invention also discloses a preparation method of the ultraviolet curing glue. The ultraviolet curing glue has the advantages of lower brittleness, favorable ultraviolet resistance, no ordor, small shrinkage stress, corrosion resistance and lower manufacture cost, is transparent and is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to an ultraviolet light curing glue and a preparation method thereof. Background technique [0002] Currently, the UV Pattern (ultraviolet mode) process provides a new key molding process. [0003] This process utilizes UV-curable glue coated on a substrate (generally PC or PET) to undergo chemical cross-linking under the trigger of UV light to cure and shape. The process is almost carried out under normal temperature and pressure, avoiding the high temperature and high pressure of injection molding; the ultra-thin and texture of the buttons are mainly controlled by the mold, and the mold used is relatively simple in design and high in precision compared with the injection mold. Therefore, UV Pattern technology has unique advantages in realizing the ultra-thin, integrated, seamless combination of keys and fine texture transfer of Keypad (miniature keyboard). [0004] High-quality Key...
