The specific embodiment

As shown in Figure 1, the luminescent film that the utility model provides has the bottom 10 of a soft light color, this bottom 10 is provided with the luminescent layer 20 with light transmission, luminescent layer 20 is provided with layer of transparent theca externa 30, the back side of described bottom 10 is provided with non-drying glue layer 40, is pasted with strippable paper 50 on the drying adhesive layer 40.

The thickness of described luminescent layer 20 is 200～500um, and described transparent theca externa 30 is polyester plastics film or PVC plastics, and its thickness is 0.01～0.2mm.

Described luminescent layer 20 is that the former powder of selecting for use of luminous pigment is the powder of 20～40um, and ratio with 10%～30% and resin raw material mixing are coated in the film that constitutes on the bottom 10.Luminescent layer 20 is made of luminous paint, luminous paint is made up of luminous pigment, organic resin, organic solvent and auxiliary agent, for fear of the crystal structure that in preparation process, damages luminescent material, cause its luminescent properties decay, can not use manufacturing process such as barreling, consider the dispersion effect of luminescent powder in resin simultaneously, preferably promptly join promptly and use, for guaranteeing the application performance of luminous paint, should consider following content in addition for the selection and the compound method of luminescent material, resin, auxiliary additive:

1, the selection of the former powder degree of luminous pigment: for solving the contradiction of dispersion effect and illumination effect, the former powder degree of luminous pigment should be selected the powder of 20～40um for use, the basic like this requirement that can satisfy the luminous paint dispersion can guarantee illumination effect preferably again simultaneously.According to different coating types, different purposes and clients diameter of particle is selected in the requirement of brightness voluntarily in addition.

2, resin choice: when selecting resin binder, should note the following aspects: (1) water white transparency and light transmission are good, particularly the ultraviolet ray transmissivity height; (2) contained fixedness resinous principle is many; (3) poisture-penetrability is little and its resistance to water is good; (4) alkali resistance is good.(5) be neutrality or faintly acid resin binder, select acrylic acid series, acroleic acid polyurethane system, acrylic acid silicon-type and fluorine resin etc. usually for use as durability.

With short-cut method preparation luminous paint, be directly to mix with luminous pigment with varnish, for guaranteeing that illumination effect preferably preferably selects the water white as far as possible varnish of light type for use, so both can avoid exciting the absorption of luminous energy, can prevent loss again to emission luminous energy.The preparation luminous paint is mainly selected varnish such as acrylic type, polyurethane-type for use.

3, the content of the former powder of luminous pigment: the main illumination effect and the integrated cost client according to luminous paint that determine of this content considers that voluntarily the content range of general luminescent powder is 10%-30% (wt).

4, the selection of auxiliary agent and consumption: for improving the flexible of luminous paint paint film and, and avoid the be full of cracks and the peeling of coating, will add an amount of plasticizer in the luminous paint to the adhesiveness of coating surface; For luminous pigment is disperseed in coating resin preferably, in case the former powder of photoluminescence pigment flocculation sediment faster preferably adds an amount of wetting dispersing agent or adds anti-settling agent.Do not influence use if precipitation takes place, fully stir before using.The consumption of auxiliary additive is generally less, adds as one feels fit according to the coating classification.

5, in mixed process, preferably use porcelain or the container of glass-lined is arranged, come dispersed color with the method for high-speed stirred.Be that minimizing precipitates, resisting medium or anti-settling agent are used in suggestion, will stir abundant, even before using.In the process for preparation, avoid contacting, avoid adding heavy metal compound with metallics

The light transmission of luminous paint is better, particularly by the advanced luminescent material coatings formulated, and the coating that its 0.1mm is thick, light transmittance reaches about 50%, sees through the color that coating can be seen bottom 10.Therefore, the noctilucence performance of coating such as twilight sunset briliancy are subjected to the influence of bottom 10 colors to a great extent.The color of bottom 10 dark more (as redness and black) is big more to the influence of noctilucence coating twilight sunset briliancy.Luminescent coating is coated with and is contained on the white bottom 10, can improve the twilight sunset efficient of coating.Generally below luminescent coating be that the end is to improve luminosity with the white primer.

Luminous paint is brushed to use, roller coating, spraying, blade coating and the spraying of pouring curtain etc.

Obtain illumination effect preferably, the luminous paint that constitutes luminescent layer 20 will guarantee coating layer thickness in work progress, minimumly will reach 100um～150um, and general coating layer thickness can be selected in 200um～500um (0.2～0.5mm).

On luminescent layer 20, constitute transparent theca externa 30, can improve coating gloss and weatherability with the varnish Lacquer finish.

Adjust paint viscosity according to construction method, stir before the use.

Luminous paint please be kept at cool place, dry place, and the time spent is not noted sealing.

This luminescent film is an adhesive sticker type luminescent film, it comprises luminescent layer 20, non-drying glue layer 40 and strippable paper 50, as increase reflector layer, then illumination effect can be better, for avoiding the ill-effect to luminescent layer such as airborne moisture, acid, alkali, dust, influence its illumination effect and service life, set up layer of transparent theca externa 30.

Luminescent layer 20 is that the coating that adopts transparency higher, printing ink, plastics etc. mix by a certain percentage in the mode of silk-screen, coated, calendering with luminescent powder and make, wherein the adding proportion of luminescent powder is 10%～30%, light emitting layer thickness is: 0.03～1mm, can select addition and light emitting layer thickness voluntarily according to specific requirement.

Transparent theca externa 30 can be selected polyester plastics film or PVC plastic foil, thickness 0.01～0.2mm.

This luminescent film is applicable to drying, clean Surface, can be made into all kinds of shapes and pattern and stick on your needed place, also can or paste some multicolour patterns at its surperficial silk-screen, be widely used in advertisement, decoration and many public places (hotel, corridor, theater, warehouse, cabin, passage etc.), also can be used for aspects such as sports products, stationery, toy, switch, valve, telephone key-press and some electronic equipments, played good indication and decorative effect.

The method for making and the luminescent film of luminous marking film are similar, in concrete manufacturing process, can select luminescent layer is back sheet, mode with silk-screen or chromatography is printed pattern, or to select non-luminous material layer be back sheet 60, print the luminous sign pattern in the mode of silk-screen or chromatography, one deck reflector layer that in fact this back sheet 60 increases, illumination effect can be better.
