Abstract

The utility model relates to a luminous leather, which is composed of a white light reflection layer and a luminescent layer. The utility model can be combined with one layer of transparent film for shapely figure and duration. The white light reflection layer is formed by the cloth, nonwoven fabric, dermis, artificial leather coated with one layer white resin or coating materials. White light reflection layer also uses the white cloth, the nonwoven fabric, the dermis, or the artificial leather. The luminescent layer is formed by the long persistence luminescent materials and resin; the resin can be PU, PVC, or acrylic resin. The transparent film uses polyester, PU, PVC, acrylic acid or nitro resin. After the leather is illuminated by light, the leather can continuously sent out the afterglow with various colors in the dark. The utility model can be made into shoes, caps, garments, tents, tarps, and various decorating tools, marks, etc. with luminescence performance at night.

Description

Luminous leather

It is leather products that the utility model relates to, and particularly has the Luminous leather of steady persistence performance.

Since embedded photoluminescent material occurred, people constantly developed its purposes.In recent years, have some industry of low-light (level), civilian luminous mark, sign, and obtained application on the daily necessities, as noctilucence telephone set (CN2177300), Safety umbrella (CN2206566), noctilucence lock (CN2031028), luminous fabric (CN2191878) etc., all be that coateds (or hot pressing) such as the coating that utilizes luminescent material (overwhelming majority utilizes zinc sulfide phosphor) to make, plastics are made, certain luminous effect is all arranged.Yet these product illumination effects are good inadequately, and kind is few.

The purpose of this utility model provides a kind of high efficiency energy storage Luminous leather, and the goods made from this leather are not through having luminous for a long time under the optical condition at night after the illumination.

Luminous leather described in the utility model can be to make with corium, also can make the artificial luminescent leather.Luminous leather is a kind of lamination layer structure, by being white reflection layer, luminescent layer in proper order from the inside to the outside, for increasing the wear-resisting and attractive in appearance layer of transparent resin protection film layer that also can increase.The white reflection layer is to scribble one deck white resin or coating on base-material, and base-material can be various clothes, non-woven fabrics, corium leather or leatheroid; Also can use white cloth, white non-woven fabrics, white corium leather or white person fabricate-leather as reflector layer.White resin coating general thickness 0.001-0.5mm is advisable with 0.01-0.1mm.Luminescent layer is to be made of long-afterglow material and resin, and wherein long-afterglow material accounts for 5-95% (W/W).Employed long-afterglow material is that the alkaline earth sulfide of active ions under existing, alkaline earth aluminate, alkaline-earth silicate etc. are arranged, and the twilight sunset of these materials presents colors such as red, orange, yellow, blue, green, the luminosity height, and its time of persistence is longer.Light emitting layer thickness is generally 0.001-1mm, is advisable with 0.03-0.3mm.The coating of reflector layer is to adopt white resin or coating, is advisable with white PU (Polyurethane) or white PVC (polyvinyl chloride); The employed resin of luminescent layer is PU, PVC or acrylic resin; The resin that transparent film layer uses is polyester, PU, PVC, PC (polycarbonate), acrylate or nitro-resin.

Reflector layer in the Luminous leather of the present utility model can absorb unabsorbed luminous reflectance to luminescent layer when rayed is arranged, i.e. the absorption of favourable light again; Issue the luminous reflectance that the light time will be transmitted into the back side in no optical condition and go out, help improving the emissive porwer of light again.Different reflector layers has different influences to illumination effect, sees the following form 1.Table 1

Annotate: experiment condition: the white reflection layer uses the PU resin, and thickness is 0.03mm, and base-material, calico, black cloth are chemical fabric; Luminous bed thickness 0.20mm uses the PU resin.All use the D65 light source, behind the 1000Lx irradiation 10min, with luminous twilight sunset tester test twilight sunset.

This Luminous leather of the present utility model has good extinction, holds luminous energy power, when visible light (sunlight, light) or other short wavelength light irradiation 20-30min is above, can be luminous at the dark place continuously, according to the sustainable 3-12h of the color of luminescent material and required after-glow light, the luminous leather that has (as yellowish green, blue green, the green isochrome) minimum visibility (0.32mcd/m of intelligent ²) can reach more than the 12h time of persistence, and can unlimitedly use repeatedly, reach identical effect.The every intensity index and the weather resistance of luminous anti-leather are fine, see Table 2.Table 2

Through the check of national authority department, this Luminous leather toxicological harmless, "dead".Because luminescent material has the twilight sunset color spectrum of broad, so that luminous leather can be launched is red, orange, yellow, blue, green, yellow, and its middle shade-orange red, orange, orchid is green, yellowish green etc.According to the needs that use, can make various footwear, cap, clothes, case and bag, and the camp, tarpaulin, harness, mark component etc. that have this leather, in the dark after illumination, send twilight sunset of all kinds serially.

Compared with prior art, the utility model is a kind of novel Luminous leather, and the luminosity height can be luminous for a long time after illumination, and purposes is more widely arranged, and can be sturdy and durable.

Accompanying drawing 1,2,3,4 is the different lamination layer structure sectional schematic diagram of the utility model Luminous leather, and wherein a layer is a binder layer; The b layer is white resin or dope layer; The c layer is a luminescent layer; The d layer is a transparent film layer; The e layer for by white cloth, white non-woven fabrics, from look corium or white person fabricate-leather constitute from the look reflector layer.

Example 1

Elastic luminous leatheroid.Base-material is a nylon loop, and scribbling thickness is 0.01-0.02mm, white flexible polyurethane resin, and it is the flexible polyurethane resin that 0.1mm contains 40% strontium aluminate (europium-dysprosium ion activating is arranged) that a layer thickness is arranged on it, outermost layer is the transparent polyester resin of thickness 0.05mm.This luminous artificial leather is compared the performance indifference with common elastic artificial leather, but emit strong yellow-green colour twilight sunset in the dark after fluorescent lamp was according to 20 minutes, twilight sunset is clearly arranged still after 8 hours.This kind leatheroid is made open-air donkey jacket, and pitch-dark dress at night was gone out very clearly to find out and was had yellow-green colour activity figure after solar radiation daytime.

Example 2

It is the orange red luminescent layer of 0.05-0.07mm that bed thickness is arranged on the white person fabricate-leather that thin type is made by non-woven fabrics, and the clear acrylic overcoating resin layer is arranged outward.Orange red luminescent layer is made for containing europium isoionic strontium sulfide calcium luminescent material and polyvinyl chloride resin.This leatheroid and common leather are made sneakers, and walking in the dark can be known and find out its orange red walking trace after illumination.

Example 3

With sheep white, that thickness is 0.4-0.5mm is reflector layer, and it is the elasticity PU resin that contains 85% strontium silicate calcium (active ions such as europium, manganese are arranged) of 0.1mm that a layer thickness is arranged thereon, and outermost layer is one deck PU transparent resin.This Luminous leather after fluorescent lamp irradiation, the luminous strong green after-glow light at the dark place, still high-visible its green glow twilight sunset behind the 8h.
