Abstract
The utility model discloses a colour polarizing diaphragm, which is composed of four layers of polyvinyl alcohol diaphragms with different thickness in superposition, wherein, each layer of polyvinyl alcohol diaphragm is processed by dipping an iodine solution and a boric acid solution and then is adhered by non cohesive gel. The manufacture of the diaphragm has simple process and low cost, but the application is wide; the advantage is very obvious especially in the application in the aspects of anti-counterfeiting and dynamic landscape painting, etc.
Description
It is colored polarizing diaphragm that the utility model belongs to a kind of polyvinyl alcohol film.
The optical polarization film that uses mostly is to adopt the long chain molecule adding inorganic iodine of a slice polyvinyl alcohol (PVA) (PVA) film that stretches to constitute at present.Common name H sheet has dichroism at visible region, and it is mainly used in optical instrument, polarizing microscope, stereotelevision etc.Progress and civilized, expanding economy along with society, on the environmental decoration of indoor and outdoor is optimized, require high more, the picture with aesthetic feeling that some are static becomes and has dynamic aesthetic feeling, landscape painting for example, be not coloured picture itself, singing of the stream and tweedle etc., also need to see flowing of water, trees, flowers and plants wave in gentle breeze etc., and this just needs film of a kind of pleochroism to come decorative picture; In addition in false proof measure, for example the bar code that is adopted, daylight fluorescence ink, magnetic ink, laser hologram etc. have reduced due anti-fake effect all because of separately some character or easily be restricted by imitated the use.
The purpose of this utility model is, a kind of colored polarizing diaphragm that is formed through being bonded together after the chemical treatment by which floor chemical film is provided, and makes it to have pleochroism, and can make anti-false sign etc.
The utility model is to realize with following technical proposal: it is formed by stacking by the polyvinyl alcohol film of four different-thickness, wherein every polyvinyl alcohol film is after iodine solution, BAS soak Tianjin processing, bonding with bonding agent, the diaphragm two sides after it is bonding scribbles the polyurethane layer.
The principal feature of this colour polarizing diaphragm is to have pleochroism, can be changed to shades of colour at visible region, as " red, green, blue, Huang " etc.It will provide a kind of new material to ornament, if can make static scenery with hills and waters become dynamic scenery with hills and waters picture, make wherein flower, wood, bird, beast etc. bright-colored, and it is true to nature to express one's feelings; Also can be applicable in addition false proof on, the anti-false sign that has replaced losing efficacy.
In conjunction with Figure of description its implementation process is described:
Fig. 1 is the main pseudosection of colored polarizing diaphragm.
By shown in Figure 1: four-level membrane is bonding forms by polyvinyl alcohol film 1,2,3,4 for this colour polarizing diaphragm, and the diaphragm above and below scribbles polyurethane layer 5.Its process is: at first prepare iodine solution (get iodine 3%, potassium iodide 6%, all the other are water); BAS (get sodium sulphate 13%, boric acid 20%, all the other are water).Behind existing polyvinyl alcohol film softening (steam), put into iodine solution earlier, put into BAS again, flood respectively and stretch.It is 0.03mm that ground floor dipping 5 minutes, stretching make thickness; The second layer soaks 2 minutes, stretching, and making thickness is 0.022mm; The 3rd layer soak 1 minute, stretching makes the thick 0.02mm that is; The 4th layer is soaked stretching in 5 minutes and makes the thick 0.032mm that is.Bonding with being drawn into thick film airing with resin glue, colored polarizing diaphragm.For protection against the tide, in diaphragm two sides brushing polyurethane layer (brushing at twice).
Claims (2)
1. colored polarizing diaphragm, it is characterized in that it by: the pure film of four layers of polyethylene that forms different-thickness through iodine solution, BAS dipping back is formed by stacking.
2. colored polarizing diaphragm according to claim 1 is characterized in that scribbling the polyurethane protective layer on the diaphragm two sides.
