Description
本發明是有關於一種合成紙之製造方法，特別是指一種將一組合物板片使用一紅外線燈照射的合成紙製造成型裝置。 The present invention relates to a method for producing synthetic paper, and more particularly to a synthetic paper manufacturing and molding apparatus for irradiating a composition sheet with an infrared lamp.
二十世紀末期出現以聚烯烴為主要材料的合成紙，因其具備了紙張和塑料的兩種性能，具有比重輕、剛性佳等優點，可在許多特殊領域取代天然紙張，例如在印刷出版方面，合成紙可以印刷耐水報刊、書籍、地圖、日曆、卡片；在商業包裝方面，可用於製造禮品袋、西裝袋、購物袋、包裝容器盒，也可用於食品、藥品、化妝品的外包裝；而在建築方面，可用於做彩色貼面紙等。 At the end of the twentieth century, synthetic paper with polyolefin as the main material appeared. Because of its two properties of paper and plastic, it has the advantages of light weight and good rigidity, and can replace natural paper in many special fields, for example, in printing and publishing. Synthetic paper can print water-resistant newspapers, books, maps, calendars, cards; in commercial packaging, it can be used to make gift bags, suit bags, shopping bags, packaging containers, and also for the packaging of food, medicine, cosmetics; In terms of construction, it can be used as a color overlay paper.
合成紙發展至今主要生產方法有壓延法、流延法、吹膜法、雙向拉伸法。其中，壓延法是生產以PP為基材的合成紙，也就是通過配料、混料、在線密煉、擠出造料、開煉至壓延，最後再分切為合成紙產品。再以雙向拉伸法來說，其基材也是PP，且其原料混配與壓延法大致相同，差異在於使用雙向拉伸機的設備，而在雙向拉伸過程中，塑料的分子鏈縱橫分布比較一致，因此，合成紙縱橫向的物理機械性能也基本相同。 The main production methods of synthetic paper have been calendering, casting, blown film and biaxial stretching. Among them, the calendering method is to produce synthetic paper with PP as a base material, that is, by batching, mixing, in-line mixing, extrusion, materializing, rolling to calendering, and finally slitting into a synthetic paper product. In the biaxial stretching method, the substrate is also PP, and the raw material mixing and rolling method are substantially the same, the difference is the equipment using the biaxial stretching machine, and the molecular chain distribution of the plastic in the biaxial stretching process More consistent, therefore, the physical and mechanical properties of the synthetic paper in the vertical and horizontal directions are basically the same.
另外，基材塑料與填充料CaCO3之間會形成一些小間隙，從而降低了合成紙的比重及成本，而形成的小間隙與光產生折射作用，使得合成紙具有珠光效果，所以在包裝、印刷、廣告等領域得到了廣泛的應用。雖然雙向拉伸法合成紙的設備昂貴，且工藝與配方技術也較為 複雜，但其製品應用範圍是最廣泛的，從而成為目前的發展主流，因此，業者無不極研發，以滿足市場的的多元需求。 In addition, some small gaps are formed between the substrate plastic and the filler CaCO3, thereby reducing the specific gravity and cost of the synthetic paper, and the formed small gap and the light refraction, so that the synthetic paper has a pearlescent effect, so in packaging, printing , advertising and other fields have been widely used. Although the biaxial stretching method is expensive, the process and formulation techniques are relatively high. It is complex, but its range of products is the most extensive, and thus it has become the mainstream of current development. Therefore, the industry has no research and development to meet the diverse needs of the market.
參閱圖1，為中華民國發明第197686號專利「雙軸延伸聚丙烯珠光合成紙提升產量產速製造方法」，該專利案揭露一種提升珠光合成紙產量、產速的製造方法，是將均勻攪拌後之樹脂層或紙面層、發泡中間層、和樹脂層或紙面層組成之組合物配方，分別擠入押出機裝置11之T型模頭內，進行共擠壓成型而形成三層樹脂組合物，並由T型模頭之出口流道流出，再經由冷卻成型裝置12、縱向延伸裝置13、橫向延伸裝置14和電暈處理裝置15和捲取裝置16，而製成產量可提升一倍以上之具有三層結構之疊層珠光合成紙。 Referring to Fig. 1, a method for manufacturing a biaxially stretched polypropylene pearlescent synthetic paper to increase the yield and production speed is disclosed in the Patent No. 197686 of the Republic of China. The patent discloses a method for improving the yield and production rate of pearlescent synthetic paper, which is to uniformly agitate. The composition of the resin layer or the paper surface layer, the foaming intermediate layer, and the resin layer or the paper surface layer are respectively extruded into the T-die of the extruder device 11 to perform co-extrusion molding to form a three-layer resin combination. And output from the outlet flow path of the T-die, and then through the cooling forming device 12, the longitudinal stretching device 13, the lateral stretching device 14 and the corona treatment device 15 and the winding device 16, the production can be doubled The above laminated pearlescent synthetic paper having a three-layer structure.
經由以上之敘述，可知習知的雙軸延伸聚丙烯珠光合成紙提升產量產速製造方法於實際使用時仍然有以下的缺點產生： From the above description, it is known that the conventional biaxially stretched polypropylene pearlescent synthetic paper manufacturing method for increasing the yield and production speed still has the following disadvantages in practical use:
一、混料不均勻 First, the mixing is uneven
習知的組合物配方僅利用押出機裝置11進行攪拌與混鍊後，即透過冷卻成型裝置12將組合物配方冷卻成型為三層疊層板片，然而，三層疊層板片僅利用單一螺桿之冷卻成型裝置12擠壓成型，恐將導致所製作之疊層珠光合成紙有混料不均勻而衍生不易上色之困擾。 The conventional composition formulation is cooled and formed into a three-layer laminate by the cooling molding device 12 only after stirring and mixing by the extruder device 11, however, the three-layer laminate uses only a single screw. Extrusion molding of the cooling forming device 12 may result in unevenness of the mixed laminated pearlescent synthetic paper and derivation of coloring.
二、效率不佳 Second, the efficiency is not good
習知利用電暈處理裝置15作高週波電暈處理，以提高珠光合成紙的表面張力，惟經過電暈處理裝置15之珠光合成紙僅用以改變被印體表面的附著能量，以符合印刷油墨的附著或塗佈，但是當製造較厚之珠光合成紙，或是使用不同組合物配方時，恐因完全乾燥的時間不同，而延長 作業人員及預留等候乾燥作業時間之降低製程效率的問題。 It is conventional to use the corona treatment device 15 for high-frequency corona treatment to increase the surface tension of the pearlescent synthetic paper, but the pearlescent synthetic paper passing through the corona treatment device 15 is only used to change the adhesion energy of the surface of the substrate to conform to the printing. Adhesion or coating of ink, but when making thicker pearlescent synthetic paper, or using different composition formulas, it may be delayed due to different drying time. The operator and the problem of waiting for the drying time to reduce the process efficiency.
三、產量不佳 Third, the output is not good
習知雖可藉由在珠光合成紙製程中，先將無機粉末預製成M1B(複合粒)，以改進習知的珠光合成紙製程中因為無機物本身受潮的因素，或表面處理劑受熱揮發產生氣體的因素，而影響產品品質與產量無法提高的問題，但是，無機粉末在押出機裝置11產速提高以及與聚丙烯混合時分散性仍有造成押出機裝置11過濾網壽命縮短，而影響生產效率與無法提高產量之目標。 Although it is known in the pearly synthetic paper process that the inorganic powder is first formed into M1B (composite particles) to improve the moisture content of the inorganic material itself in the conventional pearlescent synthetic paper process, or the surface treatment agent is heated and volatilized. The gas factor affects the problem that the product quality and the yield cannot be improved. However, the increase in the production rate of the inorganic powder in the extruder device 11 and the dispersibility when mixed with the polypropylene still cause the life of the filter device of the extruder device 11 to be shortened, which affects the production. Efficiency and the goal of not increasing production.
上述缺點都顯現習知的雙軸延伸聚丙烯珠光合成紙提升產量產速製造方法在使用上所衍生的種種問題，如能設計出可有效改善現有之合成紙製程缺點，研發出一種縮短製程時間與提升生產效率之設計，必定能達到提高效能之目標，為業者創造更大的商機，進而提升市場上的競爭力。 The above disadvantages all show various problems arising from the use of the conventional biaxially stretched polypropylene pearlescent synthetic paper to increase the yield and production speed. For example, it can be designed to effectively improve the shortcomings of the existing synthetic paper process, and develop a shortening process time. With the design of improving production efficiency, it is sure to achieve the goal of improving efficiency, creating greater business opportunities for the industry, and thus enhancing competitiveness in the market.

該塑膠原料組合物21是由該入料口512進入該混合空間510中，經該混料機511高速混合、攪拌、冷卻，使其膠化並均勻分散，以得到該膠化組合物22，再由該出料口513流出該混料機511。 The plastic raw material composition 21 enters the mixing space 510 from the inlet port 512, is mixed, stirred, cooled, and gelled and uniformly dispersed by the mixer 511 to obtain the gelled composition 22, The mixer 511 is again discharged from the discharge port 513.
該前段加熱單元52包括一用以對該膠化組合物22進行加熱處理之第三加熱件521。由於該膠化組合物22之耐溫性不佳，透過該第三加熱件521之設置，可減少該膠化組合物22硬化而無法使用之困擾。 The front stage heating unit 52 includes a third heating member 521 for heat-treating the gelled composition 22. Since the temperature resistance of the gelled composition 22 is not good, the setting of the third heating member 521 can reduce the problem that the gelled composition 22 is hardened and cannot be used.
