Abstract
The utility model discloses an optical dynamic watermarking reflective film, which comprises surface layer and glass micro-beads clinging to the surface layer, also comprising focus layer, optical layer and reflective player. The focus layer is spread on the surface of the glass micro-beads, the optical layer clings tightly to the focus layer, and the reflective layer clings tightly to the optical layer, the refractive index change range or the difference change part of the focus layer, optical layer or reflective layer is provided with watermarking graph-text. The utility model is characterized in that the refractive index change range or the difference change part of the focus layer, optical layer or reflective layer is provided with watermarking graph-text, so watermarking graph-text can be seen intermittently within 2m, dynamic watermarking situations can be observed within 10m by handy flashlight or car light at night, so that the reflective film has reflective properties and also anti-counterfeiting functions.
Description
Technical field
The utility model relates to a kind of reflective membrane, relates in particular to a kind of optics dynamic watermark reflective membrane.
Background technology
Reflectorized material (reflective membrane), it has generally included surface layer and glass microballoon, to shine most of luminous energy on the reflective membrane because of it has, be widely used in manufacturing road and traffic sign, Automobile registration, place name sign and other extraordinary boards such as (entering and exiting board) as hiring out car plate, highway card for operating board, army unit of government bodies vehicle to the characteristic of light source direction reflection.But, satisfy the employed weatherability of reflective membrane and manufacture after precision, needing to add Antiforge in manufacturing in the later stage is the work of difficulty.Particularly will add a kind of can almost be impossible with the anti-counterfeiting mark of reflective membrane term of life.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model provides a kind of optics dynamic watermark reflective membrane, has realized the existing reflective characteristic of reflective membrane, and antiforge function is arranged again.
To achieve these goals, the technical solution of the utility model is: a kind of optics dynamic watermark reflective membrane, comprise surface layer and the glass microballoon of being close to surface layer, it is characterized in that, it also comprises focus layer, optical layers, reflector layer, and described focus layer is coated in the glass microballoon surface, and described optical layers is close to focus layer, described reflector layer is close to optical layers, in the change index of refraction scope of focus layer, optical layers or reflector layer or change difference and partly be provided with and be the watermark picture and text.
Described focus layer is bowl-shape even resin bed.
Compared with prior art, the utility model is in the change index of refraction scope of focus layer, optical layers or reflector layer or change difference and partly be provided with and be the watermark picture and text, therefore can see in 2m and neglect the latent watermark picture and text that show of neglecting, also can be observed the dynamic watermark shape by torch and car light night in 10m.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2, Fig. 3 and Fig. 4 are optical schematic diagram of the present utility model.
Embodiment
See also Fig. 1, optics dynamic watermark reflective membrane of the present utility model, comprise surface layer 1 and the glass microballoon 2 of being close to surface layer 1, it also comprises focus layer 3, optical layers 4, reflector layer 5, focus layer 3 is coated in glass microballoon 2 surfaces, optical layers 4 is close to focus layer 3, and reflector layer 5 is close to optical layers 4, in the change index of refraction scope of focus layer 3, optical layers 4 or reflector layer 5 or change difference and partly be provided with and be watermark picture and text (not shown).Surface layer 1 is the weatherability resin, can be exposed at the temperature difference-40 ℃-+50 ℃ in the ultraviolet ray of sunlight and spring, summer, autumn, winter at outdoor comparatively harsh climate and long-term mouth, the etch of acid rain; Glass microballoon 2 be index of refraction at the high index of refraction glass microballoon more than 2.0, circularity, particle diameter are high transparent between 20-100 μ m, play the optical component effect in the reflective membrane material; Focus layer 3 is a high transparent resin, and allotment is coated in the glass microballoon surface at the coating of 1.4-1.5 index of refraction, and forming with the pearl face is bowl-shape even resin bed, plays the glass microballoon of focussing force by different index of refraction, and the thickness of focus layer and index of refraction are all inequality; Optical layers 4 is on bowl-shape focus layer surface, mainly is to reconcile the optics index of refraction of glass microballoon S focus layer to reach the optics balance; In optical layers surface treatment one deck reflection horizon 5, normally aluminize or other metal reflective layer, or optical layers processing multilayered medium (utilizing the reflective wavelength of λ=) is reached reflective purpose.
The production run of reflective membrane is that an optical package closely cooperates, surface layer, microballon, focus layer, optical layers, reflector layer, and the thickness and precision of each layer, transmittance, index of refraction all need to be controlled in the technical standard: thickness and precision 6=± 0.1 μ m; Index of refraction N=± 0.01.Reflective membrane in process of production, surface layer, glass microballoon, focus layer, optical layers, reflector layer, each part all is consistent (technical standard all is the same).When light source irradiation to reflective membrane, reflection luminous energy is evenly the same.The integral inverted light effect is identical, and when changing the index of refraction parameter of above material, point that is changed or face just produce difference with reflecting effect on every side, bore hole observe go on business easy.When the scope by the control break index of refraction or the difference that changes partly are picture and text, considerablely find out that watermark shape picture and text are arranged.The reflective membrane of output is fitted on sheet metal or the resin plate face through pressure sensitive adhesive, after anti-counterfeiting mark is sticked in punching press, lettering.So just finished manufacturing of whole reflective label
See also Fig. 2, light has focus layer 3, optical layers 4 through surface layer 1, glass microballoon 2 focus point end faces, last focus point A is exactly a reflective light source and to receive the eye that reflects be face on reflector layer 5 like this, and is a point in the glass microballoon back after glass microballoon focuses on.From 3 D stereo, when the three-dimensional coordinate that changes incident light source, the three-dimensional coordinate of face focus point also changes thereupon, utilize to change the required index of refraction parameter of optical watermark and be fixed on certain when a bit going up, watch and can only the some angles of corresponding three-dimensional coordinate watch when changing viewing angle, the watermark picture and text disappear thereupon.See also Fig. 3, Fig. 4, this angle of watching is controlled at very low-angle interior (in 8 degree).
Claims (2)
1, a kind of optics dynamic watermark reflective membrane, comprise surface layer and the glass microballoon of being close to surface layer, it is characterized in that, it also comprises focus layer, optical layers, reflector layer, described focus layer is coated in the glass microballoon surface, described optical layers is close to focus layer, and described reflector layer is close to optical layers, in the change index of refraction scope of focus layer, optical layers or reflector layer or change difference and partly be provided with and be the watermark picture and text.
