Abstract

The invention belongs to the field of special coatings and discloses a high water-boiling-resistant heat transfer printing coating for a ceramic and glass cup. The high water-boiling-resistant heat transfer printing coating is obtained by reacting the following components in part by weight: 10-18 parts of neopentyl glycol, 4-8 parts of trimethylolpropane, 2-5 parts of isophthalic acid-5-sodium sulfonate, 11-16 parts of hexahydrophthalic anhydride, 6-11 parts of adipic acid, 29-35 parts of deionized water, 0.05-0. 3 part of organotin catalyst, 4-10 parts of carboxyl-terminated acrylic acid prepolymer, 0.5-1 part of adhesive agent and an appropriate amount of deionized water. The high water-boiling-resistant heat transfer printing coating disclosed by the invention has the advantages of fastcuring, good water resistance, scratch resistance and high-definition heat transfer printing.

Description

technical field [0001] The invention relates to the field of special coatings, in particular to a heat-transfer coating with high boiling resistance for ceramics and glasses and a preparation method thereof. Background technique [0002] CN201710808339.8 discloses a high-performance water-based polyester resin, which is characterized in that it consists of the following raw materials in parts by mass: 2-10 parts of trimethylolpropane, 3-7 parts of neopentyl glycol, 1-5 parts of Phthalic acid, 10-14 parts of hexahydrophthalic acid, 1-3 parts of maleic anhydride, 2-4 parts of trimellitic anhydride, 2-6 parts of adipic acid, 1-3 parts of p-methoxyphenol, 10-12 parts Ethylene glycol monobutyl ether, 2-6 parts of dimethylethanolamine, 1-3 parts of dry cross-linking reinforcing agent, 1-4 parts of wetting and dispersing agent, 50-60 parts of deionized water. It has excellent hydrolysis resistance, water dispersibility and storage stability; whether this high-performance water-bas...
