Embodiment 1

[0040] This embodiment provides a preparation method of UV luminescent ink resistant to plateau climate, which includes the following steps.

[0041] (1) Preparation of luminescent materials;

[0042] ①Weigh 0.02molSrCO 3 , 0.02mol Al 2 o 3 , 0.00004mol Eu 2 o 3 , 0.00001molDy 2 o 3 , 0.000005molTb 4 o 7 , 0.00002molSiO 2 and 0.004molH 3 BO 3 As a raw material, grind the raw material in a mortar for 30 minutes, put the uniformly mixed material in a crucible and sinter for 2 hours under a weak reducing atmosphere at 1200 ° C to obtain Tb 3+ , Si 4+ Co-doped modified SrAl with a particle size of 76 μm 2 o 4 :Eu 2+ , Dy 3+ Powder. A weakly reducing atmosphere includes, for example, 5% H 2 +95%N 2 Atmosphere, 5%, 95% refer to the volume ratio. This embodiment uses Tb 3+ , Si 4+ Co-doped modified SrAl 2 o 4 :Eu 2+ , Dy 3+ , the particle size of the obtained long-lasting luminescent material is micron level, and does not need to be broken during use.

Abstract

The invention belongs to the field of printing ink preparation and discloses a method for preparing plateau-climate-resisting UV luminous ink. A doping modified micron-scale SrAl2O4: EU<2+>, Dy<3+> long-lasting phosphor material is prepared through sintering; a nano-scale SrAl2O4:EU<2+>, Dy<3+> long-lasting phosphor material is prepared through burning and is applied to the luminous ink through grading, and nano ZnO modified polyacrylic resin, nano SiO2 modified polyacrylic resin and nano TiO2 modified polyacrylic resin are mixed and evenly stirred to obtain ZnO, SiO2 and TiO2 co-doped modified polyacrylic resin which serves as the prepolymer of the ink. The process is simple and easy to realize, and the prepared UV luminous ink is high in aging resistance and wear resistance and suitable for being used on outdoor printed products in plateau areas with strong ultraviolet light and dust storm.

Description

technical field [0001] The invention belongs to the field of ink preparation, in particular to a preparation method of plateau climate-resistant UV luminous ink. Background technique [0002] As the basic raw material of the modern printing industry, the development of ink is closely related to the development of the national economy and even closer to the development of the printing industry. Benefiting from the rapid development of the domestic printing industry, my country's ink consumption, consumption of consumables, and printing consumables such as paper and cardboard have maintained double-digit rapid growth. In 2013, my country's ink output was 615,000 tons, and it is expected to exceed 800,000 in 2015. The industry generally believes that my country's ink industry is in a golden period of development. However, my country is still a developing country, and the per capita consumption of printed matter is still very low, only 5% of the per capita consumption of develop...
