Embodiment 1
[0013] A novel photocurable epoxy polyurethane resin coating for ceramics, its raw materials are proportioned as follows in parts by weight: 100 parts of bisphenol A diglycidyl ether; 40 parts of triglycidyl isocyanurate; 80 parts of diglycidyl phthalate; 30 parts of β-lactam; 75 parts of acrylic acid; 25 parts of carbon black; 10 parts of benzoin ether; 35 parts of phosphoric acid; 1 part of methyl melamine; 15 parts of antimony trioxide; 0.1 part of hydroquinone; 20 parts of titanium dioxide; 60 parts of ditricoxypropyl isocyanurate diacrylate.
[0014] After heating the above-mentioned raw materials to 90°C in a reaction kettle, stir for 12 hours and mix evenly, then coat the ceramics, and irradiate the coating film with an ultraviolet lamp.
[0015] The surface drying time of the product is 5s, and the hard drying time is 15s; there is no foaming and shedding after soaking in water for 20 days; no foaming and wrinkling after soaking in saturated calcium hydroxide for 6 day...
