Abstract

The invention relates to an aromatic ester photoinitiator for ultraviolet light-like curing and a manufacturing method thereof. The preparation method of the photoinitiator comprises two ways: a first method is to react aromatic carboxylic acid with alcohol in the presence of a catalyst to prepare the aromatic ester photoinitiator; and a second method is to react in two steps, ensure that the aromatic carboxylic acid and the alkali are acted under a backflow condition to obtain corresponding carboxylate and react the carboxylate with the diethyl sulfate to prepare the aromatic ester photoinitiator at the temperature of 0-50 DEG C. Two manufacturing methods provided by the invention have the advantages of easy operation, rapid reaction, high yield and the like.

Description

technical field

[0001] The invention relates to a photoinitiator used in an ultraviolet light curing agent and a manufacturing method thereof. Background technique

[0002] Photocuring technology is an efficient, environmentally friendly, energy-saving, high-quality material surface treatment technology, known as a new technology for the green industry in the 21st century. The most common is ultraviolet light curing, which uses ultraviolet light to quickly polymerize and crosslink chemically active liquid materials, and instantly solidify into solid materials. It has been widely used in printing, packaging, advertising, building materials, decoration, electronics, communications, computers, etc. , home appliances, automobiles, aviation, aerospace, instrumentation, sports, health and other industries. UV curing products mainly appear in the form of UV coatings, UV inks, UV adhesives, etc. UV curing products can be seen everywhere in people's daily life, and the use of UV cur...
