Abstract

The invention discloses an oligomer suitable for light-cured ink-jet ink and a preparation method of the oligomer, and belongs to the technical field of light-cured resin materials. The oligomer suitable for the photocuring ink-jet ink is mainly prepared from the following raw materials: triphenol methane triglycidyl ether, acrylic acid, 1,8-naphthalic anhydride, dicyclopentadiene and a synthetic auxiliary material; wherein the synthetic auxiliary material specifically comprises the following raw materials: hydroquinone, triphenyl phosphine, trifluoromethanesulfonic acid, p-hydroxyanisole and an ACMO monomer. The invention can effectively solve the problems that ink printing is unstable due to insufficient cohesion of low-molecular-weight UV resin in formula application of the UV ink and plug and unsmooth printing are caused due to poor compatibility and fluidity of high-molecular-weight UV resin.

Description

technical field [0001] The invention relates to the technical field of photocurable resin materials, in particular to an oligomer suitable for photocurable inkjet ink and a preparation method thereof. Background technique [0002] UV inkjet printing is a new technology developed at the end of the 20th century. It combines the advantages of inkjet printing technology and ultraviolet curing technology. Advantages in efficiency and physical properties. As one of the fastest-growing technologies in the field of UV technology, UV inkjet printing has made remarkable achievements in recent years, and its output value has increased from $3.9 billion in 2008 to $6.7 billion in 2012, and is expected to grow in 2018 to $15.9 billion. [0003] At present, the most widely used field is large-format printing, especially outdoor advertisements and road signs are very suitable for using UV platform inkjet printing technology. In addition, UV inkjet technology has also been rapidly promot...
