Abstract

The invention discloses water-soluble triazinyl sulfuryl polyurethane. The triazinyl sulfuryl polyurethane is characterized in that a preparation method comprises adding vacuum-dehydrated bis(4-isothiocyanatophenyl) sulfone and polyethylene glycol 4000 into a three-neck flask with a stirring device; adding a high boiling point solvent; stirring and reacting for 2 to 3 hours in a nitrogen or inertgas atmosphere at 65 to 75 DEG C; then adding a catalyst; raising the temperature to 80 to 85 DEG C; performing stirring reaction for 8 to 10h; then adding 2-vinyl-4,6-diamino-1,3,5-triazine and a polymerization inhibitor, continuously stirring to react for 6-8 hours, cooling to room temperature after the reaction is finished, then precipitating in acetone, carrying out suction filtration, washinga product with dichloromethane for 3-5 times, and then carrying out rotary evaporation to remove dichloromethane to obtain the water-soluble triazinyl sulfonyl polyurethane. The invention further discloses preparation and application of the water-soluble triazinyl sulfuryl polyurethane in decorative coatings of wine bottles, perfume bottles, decorative lighting, home decoration glass products, glass instruments and the like.

Description

[0001] This invention is a divisional application of the Chinese patent "An Environmentally Friendly Glass Bottle Baking Paint and Its Preparation Method".
