A kind of organic fluorescent pigment color protection film and its application method
Technical field
The invention belongs to organic fluorescent pigment technical fields, and in particular to organic fluorescent pigment color protection film and its use
Method.
Background technique
Organic fluorescence toner yellow, toner is red, and the orange pigment of toner has stronger absorption at 280 and 450nm, because
And they are commonly used in the blue-light absorbers of anti-blue light technical field.When as pigment applications for the fields such as clothes and footwear material
When, cause them to have an opportunity to absorb the purple in sunlight since wearing process is inevitably exposed to for a long time in sun luminous environment
Outer and blue light and gradually lose original color.In general, when making these clothes and footwear material fluorescence color colour band, in formula
Addition antiager and blue-light absorbers are mixed together in fluorescent pigment to prevent pigment from fading.But since addition cannot excessive (mistake
Then easily there is bloom phenomenon in amount), the part being really coated on around pigment after being dispersed is seldom, thus prevents the effect faded non-
It is often limited.
Summary of the invention
The technical problem to be solved by the present invention is to a kind of protective film for preventing organic fluorescent pigment color from changing colour and its make
Use method.
Organic fluorescent pigment color protection film composition of the present invention is by following components and quality percentage composition: optics

The optical clear resin is thermoplastic polyurethane (TPU), polymethyl methacrylate (PMMA), ethylene-vinegar
Sour ethylene copolymer (EVA) or colorless and transparent organic siliconresin.
The light stabilizer is bis- (2,2,6,6- tetramethyl -4- piperidyl) sebacates, poly-succinic (4- hydroxyl -
2,2,6,6- tetramethyl -1- piperidine ethanols) ester or 4- benzoyloxy -2,2,6,6- tetramethyl piperidines.
The antioxidant is 4,4'- thiobis (6- tert-butyl-m-cresol), four [β-(3,5- di-t-butyl -4- hydroxy benzenes
Base) propionic acid] pentaerythritol ester, dilauryl thiodipropionate or thio-2 acid 2 stearyl ester.
The light absorber is selected from absorbing wavelength range in 250 ~ 500nm, and maximum absorption wavelength range is in 400 ~ 500nm
Absorbent.The light absorber is commercially available outstanding the LQ01, outstanding the BL1227 or steady moral TM46 in Europe that is full of of being full of.
The application method of organic fluorescent pigment color discoloration protective film of the present invention, including the following steps: will be above-mentioned
Organic fluorescent pigment color protection film composition after mixing, is dissolved, composition with solvent benzol, toluene, dimethylbenzene or chloroform
Mass ratio with solvent is 1:3 ~ 5:4, after stirring and dissolving is uniform, is coated on organic fluorescent pigment colour band, vacuum drying solidification,
After solidification, organic fluorescent pigment color protection film can be obtained.
Advantages of the present invention: 1. organic fluorescent pigment color protection film composition of the invention contains light absorber, can have
The absorption of effect generates the ultraviolet and blue light of the specific wavelength of discoloration to organic fluorescent pigment color, protects it in solarization
Under it is non-discolouring.2. organic fluorescent pigment color protection film composition of the invention is easy to use, protection film composition need to only be mixed
It after closing, stir, being uniformly dissolved, is coated on organic fluorescence color belt, vacuum drying solidification, process is simple, at low cost.
