Description
Technical field
The present invention relates to a kind of energy-accumulating luminous label, be specifically related to a kind of high brightness, long-persistence luminous label, the invention still further relates to the preparation method of this luminescence scutcheon.
Background technology
Label relates to the important media in personal safety as well as the property safety field as safety, traffic, caution, prompting, fire-fighting etc., in productive life, is playing the part of indispensable role.From the angle of caution, prompting, label requires to have eye-catching understandable, long-lived characteristics usually.Present most sign manufacturing adopts common reflective membrane technology, and display effect is general, and display effect is poorer under dark environment such as night and misty rain weather, needs just can distinguish under the strong illumination.Because manufacture craft is coarse, use material poor, a lot of labels come into operation promptly begin soon to fade, get rusty, image comes off.Aging rapidly under solar radiation, wind and weather condition; Until corrosion damage; Thoroughly lose caution, suggesting effect, both brought great dangerous hidden danger, increase maintenance cost again to lives and properties; Therefore press for and employ new technology, guarantee that label can play the effect of caution, prompting really under various environment.
Energy-accumulating luminous label can improve the visual not enough shortcoming of common label; Make people rain, mist, dark, night visual isopter resolving ability difference environment descend without light-illuminating and just can clearly recognize label; Especially mountain area, township road lack lighting installation night; Common Scutcheon coating does not have the light-illuminating can not be reflective, makes pedestrian and bicycle end user can't see the sign label, causes dangerous the generation; Bring hidden danger to traffic safety, so be necessary to develop the label of suitable luminescent materials.The energy-storing self-luminescent label can active illuminating on the basis of satisfying the reflective requirement of label, has initiatively identifiability.Its visuality is superior to common label greatly under no light source, dark environment, lets the people can clear identification.Energy-storing self-luminescent label dispense with outer connecting power, but infinite loop is luminous, is energy-conserving and environment-protective product of new generation, is the developing direction that the national policy emphasis is supported.
Chinese patent CN1108413 discloses a kind of luminescence scutcheon and preparation method thereof, adopts electrostatic painting process to process protective layer on the card in one's hand surface, is becoming hide chromatograph and luminescent layer with silk screen process dry powder through high-temperature firing at character code pattern position again.The present invention adopts white resin dry powder to be fired into the screening chromatograph.Adopt luminescent material to become luminescent layer, utilize light shield layer to hide the dark brown protective layer with the transparent resin mixed sintering, bringing into play incandescnet particle effect in the luminescent layer to greatest extent, and keep incandescnet particle not with outside air contact with moisture, enhancing luminescence scutcheon luminous intensity.But still there is the problem that luminous intensity is low, fluorescent lifetime is short.
Summary of the invention
Technical matters to be solved by this invention provides a kind of energy-storing self-luminescent, long-lived high-brightness long persistence luminescence scutcheon.
For solving the problems of the technologies described above; The technical scheme that high-brightness long persistence luminescence scutcheon of the present invention is adopted is: it comprises substrate; The front of said substrate is provided with reflective membrane; Reflective membrane is provided with figure silk-screen layer, establishes talan biphenyl sodium disulfonate fluorescence coating on the silk-screen layer again, and figure does not reach and scribbled radiation proof UV gloss oil protective layer on the reflective membrane of figure covering and the fluorescence coating; Said silk-screen layer is a kind of luminous paint, and this luminous paint comprises following material by weight percentage:
Printing opacity is resin dedicated: 15～20;
PE resin: 0.8～1.2;
Dioctyl phthalate: 0.8～1.2;
