Description
本發明廢棄偏光板、片或膜之偏光材料去除碘分子處理方法，主要是針對廢電子產品的處理方式，特別是應用於廢棄偏光板、片或膜之偏光材料去除碘分子處理方法的技術上，提供一種快速，低成本，低污染的廢偏光板、片或膜的偏光材料去除方法。 The method for removing iodine molecules from the polarizing material of the discarding polarizing plate, sheet or film of the invention is mainly for the processing method of the waste electronic product, in particular, the technology for removing the iodine molecular treatment method of the polarizing material for discarding the polarizing plate, the sheet or the film. A method for removing a polarizing material of a fast, low-cost, low-pollution waste polarizing plate, sheet or film.
按，偏光板(片)是為LCD(液晶顯示器)關鍵零組件之一，其功用在於偏極化背光模組的光源之後再經由液晶分子的扭轉藉此控制液晶顯示器的明暗亮度。偏光板(片)主要的構造是以偏光膜為中心，兩側為高透明度及低光學異相性的TAC(三醋酸纖維素)，TAC外層再由PET(聚對苯二甲酸乙二酯)基材當作保護膜，而偏光膜(俗稱海苔捲)則以PVA(聚乙烯醇)吸附偏光材料後進行拉伸以製作完成。偏光材料為偏光板製造商競相開發之關鍵技術，已商業化的偏光材料大致可分為染料系偏光膜和碘系偏光膜。 According to the polarizing plate (sheet), it is one of the key components of the LCD (liquid crystal display), and its function is to control the brightness of the liquid crystal display by twisting the liquid crystal molecules after the light source of the polarized backlight module. The main structure of the polarizing plate (sheet) is TAC (triacetate cellulose) with high transparency and low optical heterogeneity on both sides, and the outer layer of TAC is further composed of PET (polyethylene terephthalate). The material is used as a protective film, and the polarizing film (commonly known as seaweed roll) is formed by adsorbing a polarizing material with PVA (polyvinyl alcohol) and then stretching. Polarized materials are the key technologies developed by polarizing plate manufacturers. Commercially available polarizing materials can be roughly classified into dye-based polarizing films and iodine-based polarizing films.
由於偏光板、片或膜為一種複合材料，難以回收使用，再者其中的偏光材料不易去除，所以目前廢棄偏光板、片或膜處理方式主要有兩個途徑一個為粉碎後送往境外作處理，但礙於法規以及成本考量其處理方式目前已漸少見，另一途徑為送往焚化爐焚毀，但因為其偏光材料於高溫焚燒後會產生大量的紫色煙霧，造成附近居民抗議，因此廢 棄偏光板、片或膜目前尚未有妥善的處理方式。 Since the polarizing plate, sheet or film is a composite material, it is difficult to recycle, and the polarizing material therein is not easy to remove. Therefore, there are two main ways to dispose of the polarizing plate, sheet or film at present, one for crushing and then sent to the outside for processing. However, due to regulations and cost considerations, the treatment methods are gradually becoming rare. Another way is to send them to the incinerator for burning. However, because the polarizing materials will burn a lot of purple smoke after high temperature incineration, it will cause protests from nearby residents. Discarding polarizers, sheets or films has not yet been properly handled.
本發明人目前從事相關產品的製造、設計，累積多年的實務經驗與心得，針對傳統習用廢棄偏光板、片或膜處理方式所既存的問題與缺失，積極地投入創新與改良的精神，所完成的廢棄偏光板、片或膜之偏光材料去除碘分子處理方法。 The present inventors are currently engaged in the manufacture and design of related products, accumulating practical experience and experience for many years, and actively investing in the spirit of innovation and improvement in order to solve the problems and defects existing in the conventional disposal of discarded polarizing plates, sheets or membranes. The polarizing material of the discarded polarizing plate, sheet or film removes the iodine molecular treatment method.
發明解決問題所應用的技術手段以及對照先前技術的功效係在於：首先利用化學處理方式將廢棄偏光板、片或膜中的偏光材料轉換為離子狀態，當偏光材料處於離子狀態時便易溶解於水中，偏光材料便可脫離廢棄偏光板、片或膜進而溶於水中，在此同時廢棄偏光板、片或膜複合材料會因為化學處理過程相繼分離，故經此階段處理後廢棄偏光板、片或膜會成為相對單純的混合廢塑膠，此時的混合廢塑膠便可拿去焚化不會產生紫色煙霧，因為此發明是利用水溶液而非有機溶劑，所以廢水處理相對環保，此外也可利用氧化還原方式再將碘離子回收，是一相對低污染(用水性溶液處理)，低成本(重量百分濃度5%的雙氧水溶液)的處理方式，具有功效上的增進，為其主要目的達成者。 The technical means applied to solve the problem and the efficacy according to the prior art are: firstly, the polarizing material in the waste polarizing plate, the sheet or the film is converted into an ion state by a chemical treatment method, and is easily dissolved when the polarizing material is in an ion state. In water, the polarizing material can be separated from the waste polarizing plate, sheet or film and dissolved in water. At the same time, the polarizing plate, sheet or film composite material will be separated due to the chemical treatment process. Therefore, the polarizing plate and the sheet are discarded after the treatment at this stage. Or the membrane will become a relatively simple mixed waste plastic. At this time, the mixed waste plastic can be incinerated without generating purple smoke. Because the invention uses an aqueous solution instead of an organic solvent, the wastewater treatment is relatively environmentally friendly, and oxidation can also be utilized. The reduction method further recovers the iodide ion, which is a relatively low-pollution (treatment with an aqueous solution), and a low-cost (5% by weight aqueous solution of hydrogen peroxide) treatment method, which has an improvement in efficacy and is the main purpose of achieving it.

為使專精熟悉此項技藝之人仕業者易於深入瞭解本發明的構造內容以及所能達成的功能效益，茲列舉一具體實施例，並配合圖 式詳細介紹說明如下：一種廢棄偏光板、片或膜之偏光材料去除碘分子處理方法，敬請參閱第一圖所示：係本發明之處理流程方塊示意圖。主要包括下列六個處理步驟：第一步驟：先將廢棄偏光板(片)或偏光膜(俗稱海苔捲)粉碎或者裁切成1cm2~3cm2的片狀物；第二步驟：將重量百分濃度5%的雙氧水加熱至80-100℃，並加熱控制在80℃以上、100℃以下；第三步驟：將粉碎後的廢棄偏光板(片)或偏光膜(俗稱海苔捲)3-5Kg投入80-100℃雙氧水之中且持續攪拌，此時利用臭氧機即刻將重量百分濃度20-80%的臭氧氣體通入雙氧水和偏光板(片)或偏光膜(俗稱海苔捲)的混合水溶液中；第四步驟：持續攪拌至偏光材料轉變為透明無色為止，此時偏光材料碘分子已經變成無色碘離子並溶解於雙氧水溶液中；第五步驟：將雙氧水溶液排除，只會剩下混合塑膠，如聚乙烯醇(PVA，Polyvinyl alcohol)，三醋酸纖維素(TAC，Cellulose triacetate)，聚對苯二甲酸乙二酯(PET，polyethylene terephthalate)三者之混合物等；第六步驟：排除的雙氧水因含有離子狀態的碘可利用氧化還原反應，加入相對於碘離子濃度的強氧化劑(如氯氣)，再把碘離子轉換回碘分子回收；混合塑膠則可於焚化爐回收熱能，或利用熱裂解方式提煉為燃料油。 In order to make it easier for those skilled in the art to understand the art to understand the construction contents of the present invention and the functional benefits that can be achieved, a specific embodiment will be listed, and the detailed description will be given as follows: a discarding polarizing plate and a sheet Or the method for removing iodine molecules from the polarizing material of the film, please refer to the first figure: a block diagram of the processing flow of the present invention. It mainly includes the following six processing steps: the first step: first crushing or cutting the discarded polarizing plate (sheet) or polarizing film (commonly known as seaweed roll) into a sheet of 1 cm 2 ~ 3 cm 2 ; the second step: the weight is 100 The hydrogen peroxide with a concentration of 5% is heated to 80-100 ° C, and the heating is controlled to be above 80 ° C and below 100 ° C. The third step is to pulverize the discarded polarizing plate (sheet) or polarizing film (commonly known as seaweed roll) 3-5 Kg. Put into 80-100 ° C hydrogen peroxide and continue to stir. At this time, use ozone machine to directly transfer 20-80% by weight of ozone gas into the mixed aqueous solution of hydrogen peroxide and polarizing plate (sheet) or polarizing film (commonly known as seaweed roll). The fourth step: continuous stirring until the polarizing material is converted into transparent and colorless. At this time, the iodine molecule of the polarizing material has become colorless iodide and dissolved in the aqueous solution of hydrogen peroxide; the fifth step: the aqueous solution of hydrogen peroxide is eliminated, only the mixed plastic remains. , such as polyvinyl alcohol (PVA, Polyvinyl alcohol), cellulose triacetate (TAC, Cellulose triacetate), polyethylene terephthalate (PET, polyethylene terephthalate), etc.; sixth step: excluded hydrogen peroxide Iodine containing ionic state can use redox reaction, add strong oxidant (such as chlorine) relative to the concentration of iodide ion, and then convert iodide ion back to iodine molecule recovery; mixed plastic can recover heat energy in incinerator, or use thermal cracking method Refined to fuel oil.
綜合上述所陳，本發明係在提供一種廢棄偏光板、片或膜之偏光材料去除碘分子處理方法，經過本發明人實際製做完成以及反覆 操作測試之後，證實的確可以達到本發明所預期的功能效益，同時又為目前坊間尚無見聞之首先創作，具有產業上的利用價值，誠然已經符合發明專利實用性與進步性之成立要義，爰依專利法之規定，向 鈞局提出發明專利之申請。 In summary, the present invention provides a method for treating iodine molecules by using a polarizing material for discarding a polarizing plate, a sheet or a film, which is completed and repeated by the inventors.
