Ultraviolet-curable extinction resin and preparation method thereof

ActiveCN103113554AGood matting effectGood anti-fouling performancePolyurea/polyurethane coatingsThioetherIsocyanate
The invention provides an ultraviolet-curable extinction resin which is obtained by reacting poly-1,4-butanediol esterdiol, trimethylolpropane, hydroxyl silicone oil, phenol thioether, diisocyanate and hydroxyl-terminated acrylate under the action of a catalyst and an inhibitor. The ultraviolet-curable extinction resin has a good extinction effect without adding extinction powders as phenyl sulfide and siloxane structures are introduced to the main chain structure of the ultraviolet-curable extinction resin provided by the invention and the group refraction coefficients of the phenyl sulfide and siloxane structures make a great difference. At the same time, the ultraviolet-curable extinction resin has good pollution resistant property as the siloxane structure is introduced into the main chain structure. The experimental results show that the vancometer adopted by the ultraviolet-curable coating prepared by the ultraviolet-curable extinction resin provided by the invention enters at 60 degrees with the glossiness of 8GU, and no imprinting is left by wiping 10 minutes later after a 3M marking pen writs on the ultraviolet-curable coating.
