preparation example Construction

[0040] The preparation method of the photocurable composition of the present invention comprises the following steps: under the conditions of constant temperature and humidity, sanitation and cleanliness, and avoiding ultraviolet radiation, it is completed through three links of pre-dispersion of ingredients, rolling and grinding, and modulation. Mix the polymerizable compound, initiator, colorant and additives at high speed to complete the pre-dispersion of ingredients; use a grinder—three-roller machine to disperse and grind the pre-dispersed materials online to the specified particle size; then add low viscosity according to the specified viscosity polymeric compound.

[0041] In another typical embodiment of the present application, a photocurable ink is provided, comprising a photocurable composition selected from any one of the above-mentioned photocurable compositions.

Abstract

The invention provides a photocuring composition and a photocuring ink. The photocuring composition comprises an olefinic unsaturated polymerization monomer with an olefinic double bond, an olefinic unsaturated polymerization oligomer and a photoinitiator, and the photoinitiator comprises a compound with a structure as shown in a structural formula I. The compound with the structural formula I has high sensitivity, high molecular weight (MW > 800), low odor, low migration, easy preparation and low in cost, has high absorption in the long-wavelength UV range of 365-405 nm, and can be well matched with a UV-LED light source. When being applied to the photocuring composition, the photocuring ink has the advantages of low mobility and long wavelength initiation, so that the obtained photocuring ink product can be safely applied to packaging materials of foods, medicines and the like.

Description

technical field [0001] The invention relates to the technical field of photocurable materials, in particular to a photocurable composition and photocurable ink. Background technique [0002] UV curing technology has become the focus of attention in today's society due to its outstanding advantages such as short curing time, fast speed, energy saving, and low pollution. The light source used in traditional UV curing is mainly high-pressure mercury lamp, but it has defects such as low energy efficiency, high heat generation, short service life, ozone pollution, and heavy metal mercury. Therefore, it is the general trend to develop and use new energy-saving and environmentally friendly curing light sources. UV-LED light source has the characteristics of high luminous efficiency, long use time, energy saving and environmental protection, and less heat release. It overcomes the shortcomings of traditional light sources and has received more and more people's favor, making it a ne...
