Abstract

The invention discloses a preparation method of a high temperature and yellowing resistant alkali-soluble epoxy acrylate UV resin. The preparation method comprises the following steps: carrying out free radical polymerization on an alicyclic epoxy acrylate monomer, glycidyl methacrylate, and hydroxyethyl methacrylate or hydroxypropyl methacrylate to prepare an alicyclic epoxy acrylate copolymer; reacting acrylic acid with an epoxy group in the above epoxy acrylate resin, and introducing a double bond to make the resin have photosensitive activity; and reacting acid anhydride with a hydroxy group, and introducing a carboxyl group to make the resin alkali-soluble in order to prepare the high temperature and yellowing resistant alkali-soluble epoxy acrylate UV resin with a carboxyl group. The glass transition temperature of the resin finally obtained in the invention is 65-100DEG C, and the finally obtained resin has the characteristics of good high temperature resistance, yellowing resistance, acid and alkali resistance of a curable film, solvent resistance, excellent mechanical performances and the like, and can be widely applied in yellowing resistant optical imaging solder resistant inks, photoresist, yellowing resistant UV inks and coatings, adhesion promoters, ink crosslinking agents and the like.

Description

technical field

[0001] The invention relates to a UV resin in the chemical field, in particular to an alkali-soluble epoxy acrylic UV resin with high temperature resistance and yellowing resistance and a preparation method thereof. technical background

[0002] Alkali-soluble UV resin is a kind of photosensitive resin that has been developed rapidly recently. Taking advantage of its alkali solubility, a variety of photo-imaging UV curing materials have been developed, and have been applied in the production of electronics and printing industries. Such as liquid photosensitive solder resist, liquid photosensitive resist, negative PS plate and flexographic plate, etc. Alkali-soluble photosensitive resins contain not only photosensitive groups, but also alkali-soluble groups such as carboxyl groups and sulfonic acid groups. Usually, the reaction of photosensitive resins with hydroxyl groups with acid anhydrides can introduce carboxyl groups, so as to obtain alkali-soluble UV ...
