[0049] Please also refer to Figure 7 and Figure 8 , Figure 7 It is a flow chart of the co-extrusion process of the multifunctional optical board in an embodiment of the present invention, Figure 8 It is a schematic diagram of the co-extrusion device made of the multifunctional optical plate of the present invention. The present invention also provides a preparation method of the multifunctional optical plate. The preparation method may include, but is not limited to the following steps:
[0050] In step1, a co-extrusion device is provided. The co-extrusion device has a plurality of extruders and a co-extrusion compound die connected to the plurality of extruders, wherein the co-extrusion compound die is provided with a plurality of runners, and the extruder The quantity of the output machine and the quantity of flow channels can be based on the specific structure of the multifunctional optical plate, for example, according to the above-mentioned Figure 3-Figure 6 The d...
Embodiment 1
[0065] Iodine-doped polyacetylene (mass concentration of iodine in polyacetylene is 1ppm-50ppm) and polymethyl methacrylate resin (number average molecular weight is 70000-80000, purchased from: Taiwan Fude Polymer Co., Ltd.) , according to the proportion of 0.1% and 99.9% of the weight, respectively, into the high-speed mixer, fully stirred to form a composition, the composition is added to the screw extruder, mixed and extruded at a temperature of 210°C-245°C , after extrusion, it is pelletized by a pelletizer and cooled to form an antistatic masterbatch for later use.
[0066] Select a co-extrusion device 100, including a first extruder 101 and a second extruder 102, add the antistatic masterbatch to the first extruder 101, and knead at a temperature of 210°C-245°C to form a melt I , the control screw 103 extrudes the melt I under the rotating speed condition of 16mm / s; Polymethyl methacrylate resin (molecular weight is 70000-80000, purchased from: Taiwan Fude Polymer Co., ...
Embodiment 2 to Embodiment 6
[0068] The preparation method of embodiment 2 to embodiment 6 is identical with embodiment 1, and difference only is that the polyacetylene (the mass concentration of iodine in polyacetylene is 1ppm-50ppm) and polymethyl methacrylate resin (number average) of iodine doping The molecular weight is 70000-80000, purchased from: Taiwan Fude Polymer Co., Ltd.) with different weight percentages, wherein, corresponding to Examples 2 to 6, the weight percentages of iodine-doped polyacetylene are 5%, 10% in turn . ) are 95%, 90%, 85%, 80%, 75% and 70% by weight in sequence.
[0069] Wherein, embodiment 2 to embodiment 6 are to further investigate the content (wt%) of polyacetylene polymer conductive material containing halogen or alkali metal in the multifunctional optical board provided by the present invention, and the influence on the performance of multifunctional optical board . In this embodiment, iodine-doped polyacetylene is used as an example, but it is not limited thereto. ...
