| titleOfInvention | Method for preparing ultraviolet (UV)-curable polyisocyanate modified superbranched epoxy acrylate |
| abstract | The invention relates to a method for preparing an ultraviolet(UV)-curable polyisocyanate modified superbranched epoxy acrylate, which comprises the following steps of: heating maleopimaric acid tri glycidyl ester, maleopimaric acid and a catalyst for esterification reaction to obtain rosin-based superbranched resin; cooling, and adding epoxy chloropropane, water and a catalyst for reaction to obtain superbranched epoxy resin; adding crylic acid, a catalyst and a polymerization inhibitor for reaction to obtain superbranched epoxy acrylic resin; and reacting the superbranched epoxy acrylic resin with ethylene glycol methacrylate terminated para toluene diisocyanate, a catalyst and a polymerization inhibitor to obtain the final product. Compared with the prior art, the method has the advantages that: rosinyl is introduced into superbranched polyester, and the hardness, strength and other special properties of the resin are improved and the curing speed is improved by utilizing the special rigid condensed ring structure of the rosin. The cured product has higher ultraviolet resistance; and by adjusting the using amount of raw materials, superbranched polyester for ultraviolet-curable coatings meeting different coating requirements can be prepared. |
