[0028] 本发明可采用两台挤出机多层共挤的方式制造。 [0028] The embodiment of the present invention may employ two extruders for producing multi-layer coextrusion. 其中两台挤出机可以是单螺杆挤出机,也可以是双螺杆挤出机。 Wherein the two extruders may be a single screw extruder may be a twin-screw extruder. 本发明专利申请特别对分流器管道和模头做了一种新型的设计,该设计可以实现几百层、上千层甚至上万层多层薄膜的制造,还可以对多层薄膜中的任一层进行厚度调整。 The present invention patent application was specifically shunt conduit and a die made of a novel design which can achieve several hundreds of layers, the manufacturing Melaleuca or even thousands of layers of the multilayer film, the multilayer film may be any of the layer to adjust the thickness.

[0029] 本发明通过一套可调节多层薄膜中任一层厚度的挤出分配系统制造出多层光学薄膜,该多层光学薄膜由折射率不同的两种透明或半透明聚合物交替叠加而成。 [0029] The present invention can be set by adjusting the thickness of any layer of the multilayer film extrusion dispensing system manufactured multilayer optical film, the multilayer optical films having different refractive indices are alternately two kinds of transparent or translucent polymer overlay made. 因为光在入射到两种不同介质的界面上时可以产生反射或折射。 Since the light may be generated when the reflected or refracted incident on the two interfaces of different media. 优选折射率差值较大的两种聚合物作为本发明所述的多层薄膜原材料。 Two large difference in refractive index is preferably the multilayer film of the polymer as the raw material of the present invention. 折射率差值越大,光从各个角度入射到多层薄膜时,其反射或透射的均一性越好。 The larger the difference in refractive index, light is incident from various angles to the multilayer film, which is reflected or transmitted, the better the uniformity. 所以,两种聚合材料的透明度,折射率差值,单种聚合物薄膜折射率的各向差异程度,各层的厚度,不同厚度层的排列方式,层的数量以及加工工艺均可对多层光学薄膜的光学性能产生影响。 Therefore, transparency of the two kinds of polymeric material, the refractive index difference, the degree of difference of each, thickness of each layer of different thickness of the layer arrangement, number, and process a single polymer film refractive index layer may be a multilayer the optical properties of the optical films impact.

[0030] 当光线入射到薄膜的前后两个界面时,若两个界面间的距离足够薄,入射光在两个界面处份反射光线可以产生干涉相消或干涉相长现象。 [0030] When light is incident to the front interface of two films, if the distance between the two interfaces is sufficiently thin, the incident light can be reflected interference light in two parts at the interface with destructive interference or long phenomenon. 干涉相消,透射率增加,干涉相长,反射率增强。 Destructive interference, transmittance is increased, the constructive interference reflectivity enhancement. 一般当单层薄膜的光学厚度(薄膜的光学厚度与物理厚度换算关系为:光学厚度=物理厚度*n,n为介质折射率。)是入射光波长的四分之一的整数倍时,反射光增强;当单层薄膜的光学厚度是入射光波长的二分之一整数倍时,透射光增强。 Generally when the optical thickness of a single layer film (optical thickness and the physical thickness of the film in terms of the relationship: the physical thickness of the optical thickness = * n, n is the refractive index of the medium) of the incident light is an integer multiple of a quarter wavelength, the reflection enhanced light; when the optical thickness of the monolayer film is an integral multiple of one-half the incident wavelength, the transmitted light is enhanced. 即单层薄膜的光学厚度是该层薄膜厚度与材料介质折射率的乘积。 I.e., the optical film thickness of the single layer film is the product of the thickness and refractive index material dielectric.

[0031] 为了提高入射光的反射效率,需要多个光学单元进行叠加,叠加的数目不能太多, 太多将增加光的散射或损耗,太少将降低所需的反射或透射功能。 [0031] In order to improve the reflection efficiency of the incident light, a plurality of optical units are superimposed, superimposed number can not be too much will increase the loss of light scattering or too little will reduce the desired reflection or transmission functions. 叠加的数目根据两种聚合物的透明度及折射率差不同也不同,聚合物越透明,折射率差值越大,需要叠加的光学单元数量越少。 The number of superimposed transparency and a refractive index difference between two kinds of different polymers are also different, the more transparent polymer, the larger the refractive index difference, the smaller the number of the optical superposition unit requires. 多个光学单元可以有不同的厚度,不同厚度的光学单元堆积方式不同,对光的反射或透射的效率也不同。 A plurality of optical units may have different thicknesses, different optical units stacked manner different thicknesses, light reflection or transmission efficiencies are different. 若需要反射可见光,则该多层薄膜的光学单元优选按照波长从小到大的方式进行堆积,先是波长较小的紫光,然后是波长较大的红光。 If desired reflect visible light, the multilayer optical film unit is preferably small to large stacked manner by wavelength, the first wavelength violet smaller then the wavelength of red light is larger. 其中适合反射单种色光的光学单元可以适当的多层堆积。 Wherein the reflective optical unit for a single color light may be suitable multilayer buildup.
