The present invention can adopt the multi-layer co-extruded mode of two extruders to manufacture.Wherein two extruders can be single screw extrusion machine, also can be double screw extrusion machine.Patented claim of the present invention has done a kind of novel design to shunt pipeline and die head especially, and this design can realize the manufacture of hundreds of layer, thousands of layer layer multi-layer film even up to ten thousand, can also carry out thickness adjustment to any layer in multilayer film.
The present invention produces multilayer optical film by the distribution system of extruding of any layer thickness in a set of adjustable multilayer film, and this multilayer optical film is alternately formed by stacking by two kinds of transparent or semitransparent polymkeric substance that refractive index is different.Because reflection or refraction can be produced when light is on the interface inciding two kinds of different mediums.The larger two kinds of polymkeric substance of preferred index difference are as multilayer film starting material of the present invention.Refractive index difference is larger, and when light incides multilayer film from all angles, the homogeneity of its reflection or transmission is better.So, the transparency of two kinds of polymeric materials, refractive index difference, single thin polymer film refractive index each to difference degree, the thickness of each layer, the arrangement mode of different-thickness layer, the quantity of layer and processing technology all can have an impact to the optical property of multilayer optical film.
When light is to former and later two interfaces of film, if the distance between two interfaces is enough thin, incident light can produce interference at two interface part reflection rays and disappears mutually or interfere mutually long phenomenon.Interfere and disappear mutually, transmissivity increases, and interferes long mutually, and reflectivity strengthens.(optical thickness and the physical thickness conversion relation of film are the general optical thickness when single thin film: optical thickness=physical thickness * n, n is medium refraction index.) when being the integral multiple of 1/4th of lambda1-wavelength, reflected light strengthens; When the optical thickness of single thin film is 1/2nd integral multiple of lambda1-wavelength, transmitted light strengthens.Namely the optical thickness of single thin film is the product of this layer film thickness and material medium refractive index.
In order to improve the reflection efficiency of incident light, need multiple optical unit to superpose, the number of superposition can not be too many, will increase scattering or the loss of light too much, very little by the reflection needed for reduction or transmission function.Superposition number according to the transparency of two kinds of polymkeric substance and refringence difference also different, polymkeric substance is more transparent, and refractive index difference is larger, need superpose optical unit quantity fewer.Multiple optical unit can have different thickness, and the optical unit accumulation mode of different-thickness is different, to the reflection of light or the efficiency of transmission also different.If desired reflect visible light, then the optical unit of these multilayer film is preferably piled up according to wavelength mode from small to large, the purple light that wavelength is less before this, is then the ruddiness that wavelength is larger.The multilayer that wherein optical unit of applicable reflection single coloured light can be suitable is piled up.
Compared with prior art, the present invention has features and beneficial effect:
(1) multilayer optical film of the present invention, the quantity because of the thickness of its each layer, thickness stack manner and layer determines the optical function of product, suitably increasing with the number of plies, and the optical property of product is also improved thereupon; The thickness of the single thin film of product of the present invention is generally no more than 1 μm, therefore can obtain the multilayer optical film that the optical unit more than by layer up to a hundred forms; Because each optical unit has one deck × material film and one deck ● material film forms, one deck × material film and one deck ● the thickness of material film can be different according to the wavelength of the light of required reflection or transmission neatly and adjust; As needed reflection wavelength to be the blue light of 570nm, then the single layer optical thickness of multilayer film can be designed to 142.5*n (nm), and n is the refractive index of this layer;
(2) multilayer optical film of the present invention, the material that one or both have birefringent characteristic is have employed in two kinds of different polymeric materials, it can be made to reflect or through polarisation of light effect more obvious, as embodiment 1-14 ~ 1-22, PEN and PET can produce birefringent phenomenon after the stretch, its polarized light volume reflection in total reflectivity amount proportion apparently higher than embodiment 1-4 ~ 1-7; Can realize piling up with less optical unit reaching specific optical effect, as embodiment 1-21, stretching ratio is larger, and the birefringent phenomenon of generation is more obvious, can reach the effect of 700 layers with the thickness of 490 layers simultaneously;
(3) product of the present invention is in manufacture method, adopts a kind of shunt die head of new design, can adjust the thickness of arbitrary individual layer in multilayer film; These multilayer film achieve in large size, the lightweight of reverberator, filter; The reflection to any wavelength light or transmission can be realized; Meanwhile, can manufacturing cost be reduced, realize mass commercial production;
(4) the present invention is by controlling vertical, horizontal stretching ratio, can the thickness of each layer of flexible, material can also be made to realize anisotropy, produce birefringence; The conservative control of processing technology especially draw ratio can make the effect of multilayer optical film better for embodiment 20, and stretching ratio increases, and transmissivity increases; Achieve stretching ratio obtained multilayer optical film under maximum tension multiplying power;
(5) product preparation process of the present invention is simple, and operation is easy, easily operates, practical.
