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 sunscr

Example Embodiment

[0072] Example 1:

[0073] Place the reaction vessel in a water bath at 40°C, and add 15L of water, 0.5mol of sodium dodecylbenzene sulfonate, 0.5mol of N,N-dimethyldodecylammonium chloride, and 0.04mol of the light Stabilizer, 0.15mol of the above-mentioned green-emitting coumarin compound G1, 0.85mol of the above-mentioned blue-emitting coumarin compound H1, stir and dissolve uniformly to form a uniform solution system; then add 20mol of styrene, 10mol of acrylonitrile, and 3.5mol of methyl Glycidyl acrylate and 16.5mol sodium vinyl sulfonate, stir vigorously to form a homogeneous emulsion; then uniformly add potassium persulfate solution (the amount of potassium persulfate solution added is 50g potassium persulfate dissolved in 200ml water) and hydrogen phosphate Disodium hydrogen phosphate solution (50g disodium hydrogen phosphate dissolved in 250 ml of water), the dropping rate of potassium persulfate solution and disodium hydrogen phosphate solution are both 100 g / hour, and...

Example Embodiment

[0074] Example 2:

[0075] Except that the compound H1 of Example 1 was replaced with H2, Example 2 was performed in the same manner as Example 1, to obtain a composite stain, named FH-2.

Example Embodiment

[0076] Example 3:

[0077] Except that the compound G1 of Example 1 was replaced with G2, Example 3 was performed in the same manner as Example 1, to obtain a composite stain, 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...
