Description
本發明係與一種瞬間加熱混合反應方法及其裝置有關,特別是指一種用於生產TPU之瞬間加熱混合反應方法及其裝置。 The invention relates to an instant heating mixing reaction method and a device thereof, in particular to an instant heating mixing reaction method and a device thereof for producing TPU.
由於熱塑性聚胺基甲酸酯(Thermoplastic Polyurethane,TPU)具有耐磨、抗撕裂性佳以及抗張強度大等物性,因此被廣泛的應用於手術手套、工業用保護膜、空氣墊、雨衣等塑膠產品上,而在現今社會中佔有胺足輕重的地位。 Thermoplastic Polyurethane (TPU) is widely used in surgical gloves, industrial protective films, air cushions, raincoats, etc. because of its good wear resistance, tear resistance and tensile strength. In plastic products, it has an important position in today's society.
一般而言,該TPU多是由一含OH之羥化合物與一含NCO之異氰酸鹽聚合物相混合所構成,但因為該含OH之羥化合物必須保持在150至250℃的溫度才可與該含NCO之異氰酸鹽聚合物順利反應成TPU,所以現有的TPU生產技術多是將該含OH之羥化合物與該含NCO之異氰酸鹽聚合物分別置放於二料桶內,並對存放有該含OH之羥化合物之料桶進行加熱,之後再將加熱後的該含OH之羥化合物與該含NCO之異氰酸鹽聚合物進行混合。 In general, the TPU is mostly composed of an OH-containing hydroxy compound mixed with an NCO-containing isocyanate polymer, but the OH-containing hydroxy compound must be maintained at a temperature of 150 to 250 ° C. The NCO-containing isocyanate polymer is smoothly reacted into TPU, so the existing TPU production technology mostly places the OH-containing hydroxy compound and the NCO-containing isocyanate polymer in the second tank. And heating the barrel containing the OH-containing hydroxy compound, and then mixing the heated OH-containing hydroxy compound with the NCO-containing isocyanate polymer.
然而上述方式必須在該料桶內設置溫度感應器,以便監測該含OH之羥化合物之溫度,但該溫度感應器在150至250℃的高溫中容易發生故障,進而影響TPU之生產良率與品質,同時讓該含OH之羥化合物保持在150至250℃更會導致該含OH之羥化合物發生變質、變色等結果,有鑑於此,坊間有業者乃提出另一種TPU生產技術,其係於該含OH之羥化合物與該含NCO之異氰酸鹽聚合物混合的過程中,進一步添加有促進劑,可供促進反應時間,使該含OH之羥化合物與該含NCO之異氰酸鹽聚合物可於較低溫的環境中順利反應形成TPU。 However, in the above manner, a temperature sensor must be disposed in the tank to monitor the temperature of the OH-containing hydroxy compound, but the temperature sensor is prone to failure at a high temperature of 150 to 250 ° C, thereby affecting the production yield of the TPU. The quality, while keeping the OH-containing hydroxy compound at 150 to 250 °C, may lead to deterioration and discoloration of the OH-containing hydroxy compound. In view of this, the manufacturer has proposed another TPU production technology, which is based on In the process of mixing the OH-containing hydroxy compound with the NCO-containing isocyanate polymer, a promoter is further added to promote the reaction time to make the OH-containing hydroxy compound and the NCO-containing isocyanate. The polymer reacts smoothly in a relatively low temperature environment to form a TPU.
但添加促進劑不僅會大幅降低TPU的物性,且會使TPU有 老化的風險,是以,本案發明人在觀察到上述缺點後,認為上述之TPU生產技術實有進一步改良之必要,而隨有本發明之產生。 However, the addition of a promoter not only greatly reduces the physical properties of the TPU, but also causes the TPU to have The risk of aging is that, after observing the above disadvantages, the inventors of the present invention considered that the above-mentioned TPU production technology is necessary for further improvement, and the present invention is produced.

為供進一步瞭解本發明構造特徵、運用技術手段及所預期達成之功效,茲將本發明使用方式加以敘述,相信當可由此而對本發明有更深入且具體之瞭解,如下所述:請繼續參閱第1圖至第5圖所示,本發明所揭示之一種瞬間加熱混合反應方法及其裝置,使用者只要先將該含OH之羥化合物存放於該第一料桶11並預加熱至該第一溫度,以及將該含NCO之異氰酸鹽聚合物存放於該第二料桶12,之後再將該第一料桶11內之含OH之羥化合物由該進口241送入該加熱通道23,並透過該第一計量器112控制流速,使該含 OH之羥化合物在20至30秒間通過該加熱通道23,並由該出口242流出該加熱通道23,藉以讓該含OH之羥化合物在通過該加熱通道23時,受該加熱器22瞬間加熱至該第二溫度,然後再將由該出口242流出之含OH之羥化合物與該第二料桶12內之含NCO之異氰酸鹽聚合物同時送入該混合單元30之混合槽31內,並透過該混合馬達33驅動該混合螺桿32轉動,使該含OH之羥化合物與該含NCO之異氰酸鹽聚合物充分混合形成一混合物,最後由該混合出口313輸出該混合物,並讓該混合物由該第一反應入口411進入該反應管41內,即可讓該混合物在流往該反應出口412時,自行反應形成該TPU彈性體。 For a further understanding of the structural features of the present invention, the application of the technical means, and the intended effect, the manner of use of the present invention will be described. It is believed that the present invention may be further understood and understood as follows: 1 to 5, the instant heating and mixing reaction method and device thereof disclosed by the present invention, the user only needs to store the OH-containing hydroxy compound in the first barrel 11 and preheat it to the first a temperature, and storing the NCO-containing isocyanate polymer in the second tank 12, and then feeding the OH-containing hydroxy compound in the first tank 11 from the inlet 241 to the heating passage 23 And controlling the flow rate through the first meter 112 to make the The OH compound passes through the heating channel 23 in 20 to 30 seconds and exits the heating channel 23 from the outlet 242, whereby the OH-containing hydroxy compound is heated by the heater 22 instantaneously as it passes through the heating channel 23. The second temperature, and then the OH-containing hydroxy compound flowing out from the outlet 242 and the NCO-containing isocyanate polymer in the second tank 12 are simultaneously fed into the mixing tank 31 of the mixing unit 30, and The mixing screw 32 is driven to rotate by the mixing motor 33 to sufficiently mix the OH-containing hydroxy compound with the NCO-containing isocyanate polymer to form a mixture, and finally the mixture is outputted from the mixing outlet 313, and the mixture is allowed to pass. The first reaction inlet 411 enters the reaction tube 41, so that the mixture reacts by itself to form the TPU elastomer when flowing to the reaction outlet 412.
藉此,可於該含OH之羥化合物與該含NCO之異氰酸鹽聚合物混合前,先透過該加熱單元20將該含OH之羥化合物瞬間加熱至該第二溫度,如此不僅可確保該含OH之羥化合物與該含NCO之異氰酸鹽聚合物能夠順利反應形成該TPU彈性體,且因為係採用輸送通過該加熱單元20之方式來瞬間提升該含OH之羥化合物之溫度,所以該含OH之羥化合物不需要長時間保持在高溫,而可克服習知TPU生產技術容易導致溫度感應器損壞以及物料變質之缺點,同時更因為本發明不需添加促進劑,所以可維持該TPU彈性體之物性與品質。 Thereby, the OH-containing hydroxy compound can be instantaneously heated to the second temperature through the heating unit 20 before the OH-containing hydroxy compound is mixed with the NCO-containing isocyanate polymer, thus not only ensuring The OH-containing hydroxy compound and the NCO-containing isocyanate polymer can react smoothly to form the TPU elastomer, and because the temperature of the OH-containing hydroxy compound is instantaneously increased by transporting through the heating unit 20, Therefore, the OH-containing hydroxy compound does not need to be kept at a high temperature for a long time, and overcomes the disadvantage that the conventional TPU production technology is liable to cause damage to the temperature sensor and deterioration of the material, and further, since the present invention does not require the addition of a promoter, the Physical properties and quality of TPU elastomers.
值得一提的是,因為該加熱通道23係由間隔設置於該加熱器22周圍之貫孔212與該連接槽213互相串接所構成,且該連接槽213之中心軸係垂直該貫孔212之中心軸,並係採直線連接於二對應貫孔212之間,所以不僅可對流經該加熱通道23之含OH之羥化合物均勻加熱,且可確保該含OH之羥化合物能夠順暢的由其中一貫孔212穿過該連接槽213進入另一貫孔212以維持流速穩定,從而使該含OH之羥化合物能夠均勻受熱且溫度維持一致。 It is to be noted that the heating channel 23 is formed by a through hole 212 spaced apart from the heater 22 and the connecting groove 213. The central axis of the connecting groove 213 is perpendicular to the through hole 212. The central axis is linearly connected between the two corresponding through holes 212, so that not only the OH-containing hydroxy compound flowing through the heating channel 23 can be uniformly heated, but also the OH-containing hydroxy compound can be smoothly smoothed therefrom.
