Abstract

The invention discloses modified light-cured polyester acrylic resin. The modified light-cured polyester acrylic resin comprises the following components in parts by mass: 100 to 120 parts of trimethylolpropane, 60 to 70 parts of benzoic acid, 50 to 60 parts of phthalic anhydride, 15 to 20 parts of xylene, 150 to 200 parts of trimethylolpropane triacrylate, 15 to 25 parts of epoxidized soybean oil, 50 to 60 parts of rosin, 30 to 40 parts of acrylic acid, 1.5 to 3.0 parts of p-toluenesulfonic acid, 1.5 to 3 parts of triphenylphosphine, 0.3 to 0.5 part of hydroquinone and 0.2 to 0.3 part of BHT.The invention also provides a synthetic method of the modified light-cured polyester acrylic resin. According to the modified light-cured polyester acrylic resin disclosed by the invention, rosin with a honeycomb structure is introduced, and epoxidized soybean oil is added, so the wetting dispersibility of the resin on organic pigment is improved, and the gloss and the transfer performance of inkare significantly improved; due to the introduction of a high-molecular-weight substance, the molecular weight of the resin is increased, the structure of the resin is more compact, the water resistance and the ink splashing resistance of the ink are improved, and the photocuring rate of the ink is increased.

Description

technical field [0001] The invention relates to the technical field of functional polymer materials, in particular to a modified photocurable polyester acrylic resin and a synthesis method thereof. Background technique [0002] Polyester acrylic resin is formed by mixing and copolymerizing acrylic acid, methacrylic acid and their esters. It is often used in the fields of coatings, printing inks and printing varnishes to wet and disperse pigments in coatings, printing inks and printing varnishes. , to promote the photocuring effect of the ink, and then improve the coating and curing effect of the material layer. [0003] However, traditional polyester acrylic resins are mostly made from low-molecular-weight polyester diols through acrylic esterification. This type of polyester acrylic resin has a low softening point, poor abrasion resistance and solvent resistance, and is harmful to organic pigments in inks. Poor wettability, poor dispersibility, poor water resistance and an...
