Preparation and use of luminous ink

luminous ink is a mixture of luminous pigment and ordinary ink in a certain proportion. After absorbing sunlight or natural light for a certain time, it can continue to emit light in the dark for more than several hours. With high heat resistance and wear resistance, it is suitable for the surface of various paper, textile, wood, plastic, metal, pottery and other materials

preparation method of luminous ink:

① luminous pigment is suitable for neutral transparent resin

② choose different types of transparent inks to prepare according to different substrates

③ noctilucent pigments with small particle sizes such as C-type, D-type and E-type shall be selected

④ the dosage of luminous pigment is generally% of the total amount, or the dosage of luminous pigment is determined according to the requirements of luminous brightness. The higher the content of luminous pigment in the ink, the higher the luminous brightness of the pattern printed by the ink and the longer the luminous time

⑤ luminous pigments cannot be ground, and can be dispersed and stirred at high speed in plastic containers such as PE or containers with glass and enamel lining

⑥ heavy metal compounds cannot be used as additives

instructions for using luminous ink:

① the viscosity of the ink is about 3000~5000 poise

② when printing, use diluent to adjust the ink viscosity according to the printing speed

③ using white backing under the luminous coating or printing directly on the white substrate can improve the brightness and luminous time of the printed pattern. If the bottom color is dark, the luminous brightness should be reduced by 50%

④ in order to obtain the luminous pattern with ideal brightness, the minimum film thickness of the luminous ink layer should not be less than 100um

⑤ because the ink layer printed with low mesh silk is thick, and the pattern with ideal luminous effect can be obtained, it is ideal to use 80- · 120 mesh silk that will show the multilayer hard protective shell adopting the new ultracom combination technology

⑥ 1kg luminous powder can be used to prepare 2L luminous ink
