▎ 摘　　要

NOVELTY - Luminous ink comprises 25-40 pts. wt. ink resin, 12-22 pts. wt. pigment, 20-55 pts. wt. base oil, 6-15 pts. wt. long afterglow luminescent material, 5-13 pts. wt. acrylate monomer, 1-3 pts. wt. photoinitiator and 5-22 pts. wt. auxiliary agent. The auxiliary agent includes 4-8 pts. wt. modified filler, 1-3 pts. wt. dispersant, 0.2-0.5 pts. wt. antioxidant, 8-15 pts. wt. diluent, 2-5 pts. wt. microcrystalline cellulose and 0.6-2 pts. wt. organosilicon antifoaming agent. USE - The ink is useful for stationery. ADVANTAGE - The ink has good luminous effect at night and long light emitting time, and improves the preparation efficiency of the luminous ink, ensures the product quality, realizes the synchronous processing of crushing and grinding, improves the material grinding efficiency, reaches the size requirement, and prolongs the luminous time after drying. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the luminous ink, comprising (i) adding ink resin into mixed grinding homogenizing device, introducing base oil, heating to 230-255℃, keeping the temperature and stirring uniformly to obtain connecting material; (ii) adding pigment into the mixed grinding homogenizing device, long afterglow luminescent material, stirring uniformly, grinding and crushing, filtering to obtain pre-dispersed material with grain diameter of 10-15 m; and (iii) adding the pre-dispersed material and diluent, acrylate monomer, photoinitiator, modified filler, dispersant, antioxidant, microcrystalline cellulose, organosilicon defoaming agent into the mixed grinding homogenizing device, emulsifying and homogenizing to obtain mixed material, allowing to stand the mixed material, and filtering.
