Problems solved by technology

[0008] However, the preparation process of these materials is complicated, or the organic fluorescent substances used have weak absorption of ultraviolet rays and thus weak luminescence, and the stability of a single organic fluorescent dye to ultraviolet light and heat is weak, resulting in poor fatigue resistance. Loss of activity after a period of time can no longer act as a sunscreen
[0009] Theoretically, the energy transfer between chromophores in the overlapping region of the acceptor chromophore absorption spectrum and the donor fluorescence emission spectrum can be used to adjust the photoexcitation wavelength and light emission color, but the prior art has not applied this theoretical model to the function In the preparation of permanent composite pigments

Embodiment 1

[0073] Place the reaction vessel in a water bath at 40°C, add 15 L of water, 0.5 mol of sodium dodecylbenzenesulfonate, 0.5 mol of N,N-dimethyldodecyl ammonium chloride, and 0.04 mol of the above-mentioned light Stabilizer, 0.15mol of the above-mentioned green light-emitting coumarin compound G1, 0.85mol of the above-mentioned blue light-emitting coumarin compound H1, stirred and dissolved evenly to form a uniform solution system; then add 20mol of styrene, 10mol of acrylonitrile, 3.5mol of methyl Glycidyl acrylate and 16.5mol sodium vinyl sulfonate are stirred vigorously to form a uniform emulsion; then potassium persulfate solution is added dropwise evenly (the amount of potassium persulfate solution is 50g of potassium persulfate dissolved in 200ml of water) and hydrogen phosphate Disodium solution (disodium hydrogen phosphate solution add-on is that 50g disodium hydrogen phosphate is dissolved in 250ml water), the rate of addition of potassium persulfate solution and disodi...

Embodiment 2

[0075] Except that the compound H1 of Example 1 was replaced by H2, Example 2 was carried out in the same manner as Example 1 to obtain a composite dyeing agent named as FH-2.

Embodiment 3

[0077] Example 3 was carried out in the same manner as in Example 1 except that the compound G1 in Example 1 was replaced by G2 to obtain a composite dye named FH-3.

Abstract

The invention relates to a composite coloring agent which comprises polymer substrates, surface active agents, a coumarin compound emitting blue light, a coumarin compound emitting green light and a light stabilizer. Meanwhile, the invention further relates to a preparation method of the composite coloring agent in a solvent-free condition. The composite coloring agent shows strong fluorescence emission, glossiness and sunlight fastness, and shows quite good light and heat stability.

Description

technical field [0001] The invention relates to a composite dyeing agent, more specifically relates to a composite dyeing agent with sunscreen function, and belongs to the field of functional pigments. Background technique [0002] Fluorescent pigments or dyes are widely used in children's toys, clothing, packaging, textiles, plastic coloring, paints, inks, printing and dyeing, etc., and can be used as silk, thread or sunscreen fabrics for clothing trademarks and luminous warnings. Fluorescent substances currently used in fluorescent pigments include natural organic fluorescent substances: benzothiazole fluorescent compounds, benzoxazole fluorescent compounds, pyridinephenol fluorescent compounds, quinazolinone fluorescent compounds, xanthene compounds, transition metals Complex fluorescent compounds, quantum dots, rare earth fluorescent materials. [0003] Currently, some fluorescent pigments or dyes have been reported, such as: [0004] CN102926185A discloses a polyester...
