Abstract

The invention discloses a photoinitiator based on cyclohexanedione-fused cyclodiene and a synthesis method of the photoinitiator. The synthesis method comprises the following steps: adding cyclohexanedione and a dialdehyde (or ketone) compound into methanol according to a molar ratio of 1:1:1, dropwise adding an alkaline solution, keeping a dark condition, introducing nitrogen for protection, and conducting reacting at 20-100 DEG C for 3-12 hours to obtain a faint yellow solid; and recrystallizing the prepared faint yellow solid by using ethanol to obtain the photoinitiator based on cyclohexanedione-fused cyclodiene. The photoinitiator with the structure as shown in a general formula (I) is generated through the reaction of the photoinitiator, and the photoinitiator has the advantages of being simple in synthesis, high in visible light utilization rate, non-toxic, odorless, free of yellowing and the like, has good initiation efficiency under an LED light source, can be used under the LED light source and is wide in application range.

Description

Technical field [0001] The present invention belongs to the field of organic chemistry, and is specifically a photoinitiator based on cyclohexadric albicide and its synthesis method thereof. Background technique [0002] Light curing refers to the process of forming a solid product in an irradiation of the photoinitiator in an irradiation of ultraviolet light or visible light to form a solid product. The photocurable reaction has the characteristics of fast curing speed, energy saving, low curing temperature and low availability, and controllability; in addition, high-crosslinking density, mechanical properties, thermal stability, good thermal resistance, solvent-resistant Strong. Photopolymerization technology is widely used in the fields of coatings, adhesives, printing, biological materials, microelectronics. [0003] The photopolymerization system generally includes the following major three components: oligomers, monomers (also known as active diluents), and photoinitiators....
