Problems solved by technology

[0009] Theoretically, the energy transfer between the chromophores in the overlapping region of the guest chromophore absorption spectrum and the host fluorescence emission spectrum can be used to adjust the optical excitation wavelength and light emission color, but the prior art has not applied this theoretical model for functional compounding mixing of paint

preparation example 1

[0050] Preparation Example 1: Synthesis of Light Stabilizer

[0051] Take 10.12 g EV80 (α-[3-[3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl]-1-one propyl]-ω-hydroxy poly(keto-1,2-ethanediyl)) into a 50 ml separable reaction flask, stirred and heated to 50°C, added 1,3,5-tris(6-iso Cyanatohexyl)-1,3,5-triazine-2,4,6-trione 4.04 g, N,N-dimethylacetamide 3.55 g, heated to 90°C, reacted for 2-3 hr (titration After the number of moles of NCO functional groups reached the end point of the reaction), the temperature was lowered to 70°C and 1.22 g of N,N-dimethylacetamide and 0.53 g of 2,2-bis(hydroxymethyl)butanoic acid were added, and the temperature was raised to 90°C to react 2- After 3 hr (titration of the molar number of NCO functional groups reaches the end of the reaction), cool down to 50°C to obtain the light stabilizer shown in the following formula (according to the general molecular weight measurement method, record its weight average molecular weight ...

preparation example 2

[0054] Preparation Example 2: Synthesis of Tb-DTPA Complex

[0055] Diethyltriaminepentaacetic acid (DTPA) was dissolved in anhydrous methanol to form 1 × 10 -3 mol / L solution, add triethylamine in an equimolar amount to the carboxyl group in the organic ligand, and then add an equimolar amount of terbium nitrate under stirring. After stirring for 2 h, remove the solvent on a rotary evaporator to precipitate out, filter , after washing with methanol, the solid was dried to obtain a Tb-DTPA complex with diethyltriaminepentaacetic acid (DTPA) as a ligand, which was reserved for future use.

preparation example 3

[0056] Preparation Example 3: Synthesis of Eu-DTPA Complex

[0057] Preparation Example 3 was implemented in the same manner as Preparation Example 2, except that Europium Nitrate was used instead of Terbium Nitrate, thereby preparing Eu-DTPA complex.

Abstract

The invention relates to composite pigment powder. The composite pigment powder comprises coloring agents, photosensitive dyes, rare-earth complexes, a light stabilizer and a dispersing agent in a certain molar ratio. Through specific combination or selection of the components in proportion, the composite pigment shows strong fluorescence emission and very good light stability and exterior durability and gains unexpected synergistic technical effects. The composite pigment powder can be applied to various fields such as fluorescence labels, textile coloring agents, paints, varnish, printing ink and the like, and has wide industrialization prospects and market values.

Description

Technical field [0001] The present invention involves a pigment powder, and it is more specifically involved in a composite pigment powder with fluorescent warning signs, which belongs to the field of functional pigments. Background technique [0002] Fluorescent pigments are widely used in children's toys, clothing, packaging, textiles, plastic coloring, coatings, inks, printing and dyeing and other fields, which can be used as silk, lines, or inks used for clothing trademarks, luminous alarms.The fluorescent substances currently used in fluorescent pigments include natural organic fluorescent substances: phenylpidazole fluorescent compounds, phenylizole -like fluorescent compounds, pyridine phenol fluorescent compounds, chimodolinone fluorescent compounds, 呫 ton -type compounds, transition metal metalsCombined with fluorescent compounds, quantum dots, and rare earth fluorescent materials. [0003] Among them, rare earth fluorescence materials are a type of light -emitting mater...
