Abstract

The utility model provides a high-brightness super-long afterglow luminous plastic film, which belongs to a luminous device. The high-brightness super-long afterglow luminous plastic film comprises a luminous plastic layer which is formed by mixing super-long afterglow luminous powder, high-brightness long afterglow luminous powder, and plastics, and the high-brightness super-long afterglow luminous plastic film also comprises a reflective layer, a protective layer, a patterned layer, a plastic encapsulated layer, and a sticker layer which are combined. The high-brightness super-long afterglow luminous plastic film can be manufactured to be the type of the instant plaster of the sticker or the pressure sensitive adhesive tape. After the illumination, as the high-brightness super-long afterglow luminous plastic film can continuously emit light for a plurality of ofdays to a week in the dark, the utility model can be used in any place which needs marks in the dark, the emergency evacuation marks of the passages of the places, such as a basement, a tunnel, a subway, an underground market, a ship, a cinema, etc., and all kinds of power switches, plugs, sockets, household appliances, door plates, etc.

Description

High-brightness superlong aftergrow luminous plastic film

The utility model relates to a kind of long-persistence luminous plastic foil that overlength afterglow luminescent powder and high-brightness long persistence luminescent powder is mixed with plastics and make, to be applied in the dark the show label as the low light level, label etc.It belongs to luminescent device, fields such as plastic products and sign label.Specially refer to a kind of coldly,, can store certain luminous energy after blue light or the white light, progressively emit light then in the dark at ultraviolet light, with satisfy without any light source show for a long time down the requirement of sign of palpus.Because it is it can be made into the form of adhesive sticker plastic foil, therefore easy to use.

Long after glow luminous material in the past such as ZnS:Cu, ZnS:Cu Co, ZnS:Cu Mn Co etc., though original intensity is higher, but after time is shorter, generally half an hour by 2-3 hour, when it mixes with plastics and the long-persistence luminous plastic foil made is being subjected to illumination just to be difficult to later in 2-3 hour in the dark later on see, so usable range has been subjected to very big restriction.The new overlength afterglow luminescent material with SrAlOs:Eu type (as patent CN 1053807A) and other type that occurs recently surpasses 24 hours its after time, so that can also see in the dark after the week, but its original intensity is low.The utility model is that above-mentioned two kinds of luminescent materials or multiple luminescent material are mixed in certain proportion.Be mixed and made into luminescent plastic film (said plastics can be PEFs, polystyrene, polyvinyl chloride, organic glass, epoxy resin etc.) in certain proportion here with this mixed powder and plastics.Perhaps two kinds of luminescent materials or multiple luminescent material and plastics are mixed and made into the long-persistence luminous plastic foil of multilayer, to reach the requirement of high brightness and overlength afterglow.

It is a kind of very easy that the purpose of this utility model is to provide, and do not need power supply, cold again luminous sign.It is by day general daylight lamp or have the irradiation of light source of certain blue streak composition after have a power failure in the dark or suddenly the back in considerable time promptly 24 hours so that still can see the luminescent device of original sign after the week.It can be widely used in various basements, the tunnel, and the tunnel, the market place builet below the ground, boats and ships, movie theatre, road sign emergency evacuation labels such as emergency access, daily power switch, edge connector, low-voltage electrical apparatus, doorplate waits all to wish to see the place of its sign when no light source.

Specify structure of the present utility model below.

Basic structure of the present utility model is below the luminescent plastic layer that is mixed and made into by long-afterglow luminescent powder and high-brightness long persistence luminescent powder and plastics the reflection horizon to be arranged successively, plastic packets seal, and non-drying glue layer.And on the luminescent plastic layer matcoveredn, patterned layer, the plastic packets seal is formed.Whole luminescent plastic film can stick on transparent plastic plate or other substrate.Wherein Guan Jian one deck be luminescent layer it have two kinds of structures, first kind is by with ZnS:CuCo, the long after glow luminous material of ZnS:CuEu and other high brightness and plastics are first luminescent layer made of scope according to a certain percentage, and its thickness is to prepare one deck overlength afterglow luminescent layer on ground floor again at the 0.05-1mm second layer.It is by making second luminescent layer of thickness at 0.05-0.5mm according to a certain percentage with this class of SrAlOs:Eu or other overlength afterglow luminescent material and plastics.To make the luminescent plastic layer of sandwich construction.Second kind of structure be the mixed type single layer structure it be by the luminescent material of high-brightness long persistence luminescent material (as ZnS:CuCo etc.) and overlength afterglow luminescent material (as SrAlOs:Eu) and other type with arbitrary proportion mix the back and then with the luminescent plastic layer of making thickness meaning 0.2-1mm after plastics mix in certain proportion.

On the luminescent layer of above-mentioned multilayer or single layer structure, one side if be used for single face show then luminescent layer prepare one deck reflection horizon, this layer reflection horizon should be made in the one side of high-brightness long persistence luminescent layer to first kind of double-deck luminescent layer.In use clean and prevent after being convenient to for the surface state that will obtain and wear out, can coat layer protective layer on the surface of luminescent layer.It is to be smeared on the outer surface by pure plastics, and these plastics can be that the plastics that above-mentioned luminescent layer is used also can be the water proof type protective seams of Si rubber and so on.Its thickness is at 0.1-0.2mm.Then do not add reflector layer for the luminescent layer of double-sided display and all do the last layer protective seam on both sides; on light-emitting area, do the last layer patterned layer then; it is to print with tiffany; spraying; method such as clip and paste is done required figure and literal; the film luminous to single face can be coated with the last layer adhesive sticker at the back side in reflection horizon, but makes the instant paster of overlength afterglow light-emitting film adhesive sticker of cutting stickup or the form of band, uses with convenient.As sealing formation plastic packets seal, to protect this film without adhesive sticker or then available two overlays of light-emitting film that are used for double-sided display.
