Abstract

The invention discloses a thioxanthone dicarboamide compound and a preparing method and application thereof. The structural formula of the thioxanthone dicarboamide compound is shown in the specification. The thioxanthone dicarboamide compound is used as a UV-LED photoinitiator for photopolymerization of a vinyl unsaturated resin system, and can be applied to the photocuring field, the photopolymerization field and the photocrosslinking field.

Description

Technical field [0001] The invention relates to the field of photopolymers, and mainly relates to a thioxanthone dimethylformamide compound and a preparation method and application thereof. Background technique [0002] UV-LED (UV Light Emitting Diodes) photopolymerization refers to a photopolymerization method that uses ultraviolet light emitting diodes as the energy output light source. Due to its advantages of low temperature, energy saving, low power consumption, long service life, single emission wavelength, etc., replacing the traditional high-pressure mercury lamp curing method has become the future development direction. It has been involved in traditional printing and coating fields such as coatings, adhesives, inks, printing plates, microelectronics, etc., and has further expanded to bone and tissue engineering biological materials, surface etching gratings, material surface modification, active / reactive Controlled polymerization and other fields, especially suitable f...
