Description
本發明係關於一種聚酯母粒、聚酯瓶胚及聚酯瓶體，尤指一種紅外線吸收聚酯母粒、可吸收紅外線的聚酯瓶胚及具良好色澤的聚酯瓶體。 The invention relates to a polyester masterbatch, a polyester preform and a polyester bottle, in particular to an infrared absorbing polyester masterbatch, an infrared absorbing polyester preform and a polyester bottle having good color.
由於聚酯製成的包裝瓶係具備良好的透明度及強度等特性，使得聚酯深受包裝瓶製造業者的喜愛。現有技術於製作聚酯瓶時，係先將聚酯經由切割製成聚酯粒，再透過射出成型技術將該酯粒製成聚酯瓶胚(parison)，然後以紅外線石英燈對該聚酯瓶胚加熱使該聚酯瓶胚軟化並透過吹塑成型技術將軟化的聚酯瓶胚製成所需形狀的聚酯瓶體。 Because of the good transparency and strength of the bottles made of polyester, polyester is very popular among bottle manufacturers. In the prior art, in the production of a polyester bottle, the polyester is first cut into polyester pellets, and then the ester pellet is made into a polyester preform by an injection molding technique, and then the polyester is irradiated with an infrared quartz lamp. The preform heating softens the polyester preform and produces the softened polyester preform into a desired shape of the PET bottle by blow molding techniques.
紅外線為電磁波的一種。在光譜分佈中，波長在0.76微米(μm)到1000μm間之區間被界定為紅外線。通常又區分成三個區間：長波段(3μm至1000μm)、中波段(1.4μm至3.0μm)和短波段(0.76μm至1.4μm)。目前業界於紅外線加熱技術中，所選用之石英燈之所產生的紅外線的最大輻射能量之波長係介於1.1μm至1.2μm之間，係屬於中波段。而現有技術之聚酯瓶胚所能吸收的紅外線之波長屬於長波段的5.5μm至10μm。因此，聚酯瓶胚無法完全吸收來自石英紅外線燈管放出之輻射能量，造成現有 技術之紅外線石英燈必須長時間持續對該聚酯瓶胚加熱，才能使該聚酯瓶胚吸收足夠紅外線而達到軟化以製得聚酯瓶體，從而使得聚酯瓶體之生產效率不彰且耗能。 Infrared is a kind of electromagnetic wave. In the spectral distribution, a wavelength between 0.76 micrometers (μm) and 1000 μm is defined as infrared rays. It is usually divided into three sections: a long wavelength band (3 μm to 1000 μm), a medium wavelength band (1.4 μm to 3.0 μm), and a short wavelength band (0.76 μm to 1.4 μm). At present, in the infrared heating technology, the maximum radiant energy of infrared rays generated by the selected quartz lamp is between 1.1 μm and 1.2 μm, which belongs to the middle band. The wavelength of the infrared ray that the prior art polyester preform can absorb is 5.5 μm to 10 μm in the long wavelength band. Therefore, the PET preform cannot completely absorb the radiant energy emitted from the quartz infrared lamp, resulting in the existing The infrared quartz lamp of the technology must continue to heat the polyester preform for a long time, so that the polyester preform absorbs enough infrared rays to soften to obtain a polyester bottle body, thereby making the production of the polyester bottle body inefficient. Energy consumption.
為此，現有技術提供數種聚酯組成物，該等聚酯組成物分別包含有不同紅外線吸收粒子，以試圖改善聚酯之紅外線吸收能力不佳的問題。舉例而言，歐盟專利公告第0884365號案係以石墨(graphite)為紅外線吸收粒子；美國專利公告第6503586號案係以銅鉻尖晶石(copper chromite spinel)作為紅外線吸收粒子；美國專利公告第7368523號案及第8445086號案均以氮化鈦(titanium nitrate)作為紅外線吸收粒子；美國專利公告第7745512號案係以碳包覆之金屬鐵(carbon-coated iron)作為紅外線吸收粒子；美國專利公告第8735452號案則是以鎢鈦碳(WTiC)合金作為紅外線吸收粒子。 To this end, the prior art provides several polyester compositions which each contain different infrared absorbing particles in an attempt to improve the problem of poor infrared absorbing ability of the polyester. For example, EU Patent Publication No. 0884365 uses graphite as an infrared absorbing particle; US Patent Publication No. 6503586 uses copper chromite spinel as an infrared absorbing particle; US Patent Publication No. Titanium nitride is used as the infrared absorbing particle in both cases 7368523 and 8445086; the carbon-coated iron is used as the infrared absorbing particle in the US Patent Publication No. 7745512; Announcement No. 8735452 is a tungsten-titanium carbon (WTiC) alloy as an infrared absorbing particle.
藉由紅外線吸收粒子的使用，雖然能改善前述聚酯瓶胚的生產效率不佳及耗能之問題，但現有技術所使用的紅外線吸收粒子(諸如前述的石墨、銅鉻尖晶石、氮化鈦、碳包覆之金屬鐵及鎢鈦碳合金)，除了吸收紅外線也會吸收一部分可見光故皆為黑色或灰色，使得含有前述種類的紅外線吸收粒子的聚酯瓶胚所製得的聚酯瓶體之色澤低且帶有淡灰黑色。 The use of infrared absorbing particles can improve the production efficiency and energy consumption of the aforementioned polyester preforms, but the infrared absorbing particles (such as the aforementioned graphite, copper chrome spinel, nitriding) used in the prior art. Titanium, carbon-coated metal iron and tungsten-titanium carbon alloy), in addition to absorbing infrared light, absorbs a part of visible light, so it is black or gray, so that the polyester bottle made of the polyester preform containing the above-mentioned kind of infrared absorbing particles The body has a low color and a light grayish black color.
具體而言，以石墨為例，雖然其可吸收之電磁波波長為0.25μm至2.5μm，能完全涵蓋石英燈放出之紅外線的最大輻射能量之波段(1.1μm至1.2μm)。但是由於可見光之波段為380nm至780nm，故石墨除了吸收紅外線 見光之波段為380nm至780nm，故石墨除了吸收紅外線外也會吸收全部的可見光，不僅使得石墨呈現黑色，連帶使得含有以石墨為紅外線吸收粒子的聚酯瓶胚除了吸收紅外線外也會吸收一部份的可見光，進而使得該聚酯瓶體製得的聚酯瓶體之色澤低且帶有淡灰黑色。 Specifically, in the case of graphite, although the wavelength of the absorbable electromagnetic wave is 0.25 μm to 2.5 μm, the wavelength band (1.1 μm to 1.2 μm) of the maximum radiant energy of the infrared ray emitted from the quartz lamp can be completely covered. However, since the visible light band is 380 nm to 780 nm, graphite absorbs infrared rays. Seeing the band of light is 380nm to 780nm, graphite absorbs all visible light in addition to infrared rays, which not only makes the graphite appear black, but also makes the polyester preform containing graphite as infrared absorbing particles absorb the infrared light. Part of the visible light, in turn, makes the polyester bottle body of the polyester bottle body with low color and light gray black.
因此，由於現有技術之含有上述種類的紅外線吸收粒子的聚酯組成物所製得的聚酯瓶體在吸收紅外線時也會吸收可見光，使人不易辨識容置於由聚酯瓶胚所製得之聚酯瓶體內的內容物的顏色，還產生視覺感官不佳之缺點，從而降低飲品業者使用的意願。 Therefore, the polyester bottle obtained by the polyester composition containing the infrared absorbing particles of the above kind in the prior art absorbs visible light when absorbing infrared rays, making it difficult for people to recognize and accommodate it by the polyester preform. The color of the contents of the polyester bottle also has the disadvantage of poor visual sense, thereby reducing the willingness of the beverage industry to use.

The results of this test example are shown in Tables 1 and 2.
測試例2 色澤色度儀測試 Test Example 2 Colorimeter Test
以一色澤色度儀量測各實施例及各比較例之聚酯瓶體之色澤值(L值)。該色澤色度儀係為日本柯尼卡美能達(Konica Minolta)株式會社之CM-2600，係採用國際照明委員會(Commission Internationale d'Eclairage)之L*、a*、b*色彩空間(color space)原理。該色澤色度儀測得之L值係為衡量聚酯瓶體之色澤的標準；L值越高，色澤越白； 反之，L值越低，色澤越黑。以比較例1為基準，並計算比較例1之L值與各實施例之L值及其他比較例之L值的差異(△L，△L定義為比較例1之L值減各實施例之L值或其他比較例之L值)，並以△L作為實施例聚酯瓶體色澤之指標，；其中，△L值越小，表示有添加紅外吸收粉體的聚酯瓶體之色澤和未添加紅外線吸收粉體的聚酯瓶體之色澤差異越小。在，反之，△L值越大的表示有添加紅外吸收粉體的聚酯瓶體的色澤和未添加紅外線吸收粉體的聚酯瓶體的色澤差異越大。本測試例之結果示於表1及2中。 The color value (L value) of the polyester bottle bodies of the respective Examples and Comparative Examples was measured by a color shade meter. The color colorimeter is CM-2600 of Konica Minolta Co., Ltd., which adopts the L*, a*, b* color space of the Commission Internationale d'Eclairage. )principle. The L value measured by the color colorimeter is a standard for measuring the color of the polyester bottle body; the higher the L value, the whiter the color; Conversely, the lower the L value, the darker the color. Based on Comparative Example 1, the difference between the L value of Comparative Example 1 and the L value of each Example and the L value of the other comparative examples was calculated (ΔL, ΔL was defined as the L value of Comparative Example 1 minus the respective examples. L value or other comparative example L value), and ΔL is used as an indicator of the color of the polyester bottle body of the embodiment; wherein, the smaller the ΔL value, the color of the polyester bottle body to which the infrared absorbing powder is added The difference in color between the polyester bottles to which the infrared absorbing powder is not added is smaller. On the other hand, the larger the ΔL value, the greater the difference in color between the color of the polyester bottle to which the infrared absorbing powder is added and the color of the polyester bottle to which the infrared absorbing powder is not added. The results of this test example are shown in Tables 1 and 2.
如表1及2所示，比較例2之聚酯瓶胚之△T僅為0.01，而實施例7、10、15及18之聚酯瓶胚之△T均可達到1.1℃以上；可見，當所製得的聚酯瓶胚中的紅外線吸收粉體之含量相同(5ppm)，相較於比較例2以石墨為紅外線吸收粉體的紅外線吸收聚酯母粒所製得的比較例2之聚酯瓶胚，實施例7、10、15及18之以含有摻雜有銫之三氧化鎢、摻雜有銫與氯之三氧化鎢、摻雜有銫與錫之三氧化鎢及摻雜有銫與銻之三氧化鎢作為紅外線吸收粉體的紅外線吸收聚酯母粒所製得的聚酯瓶胚於受紅外線照射後係能快速升溫，從而能提高聚酯瓶體的生產效率。 As shown in Tables 1 and 2, the ΔT of the polyester preform of Comparative Example 2 was only 0.01, and the ΔT of the polyester preforms of Examples 7, 10, 15 and 18 could reach 1.1 ° C or more; When the content of the infrared absorbing powder in the obtained PET preform was the same (5 ppm), Comparative Example 2 prepared by comparing the infrared absorbing polyester masterbatch in which graphite was an infrared absorbing powder of Comparative Example 2 Polyester preforms, Examples 7, 10, 15 and 18 contain tungsten trioxide doped with antimony, tungsten trioxide doped with antimony and chlorine, tungsten trioxide doped with antimony and tin, and doped The polyester preform produced by the infrared absorbing polyester masterbatch having the antimony and antimony trioxide as the infrared absorbing powder can rapidly heat up after being irradiated with infrared rays, thereby improving the production efficiency of the polyester bottle body.
如表1及2所示，比較例2及3之聚酯瓶體之△L分別僅為10.76及31.69，而實施例1至19之聚酯瓶體之△L均小於3.8；由此可見，實施例1至19之聚酯瓶體係具有較比較例2及3之聚酯瓶體為白的色澤，則實施例1至19之聚酯瓶體的色澤較較比較例2及3之聚酯瓶體的色澤為佳。 As shown in Tables 1 and 2, the ΔL of the polyester bottles of Comparative Examples 2 and 3 were only 10.76 and 31.69, respectively, and the ΔL of the polyester bottles of Examples 1 to 19 was less than 3.8; The polyester bottle systems of Examples 1 to 19 have a white color than the polyester bottles of Comparative Examples 2 and 3, and the polyester bottles of Examples 1 to 19 have a higher color than the polyesters of Comparative Examples 2 and 3. The color of the bottle is better.
如表1所示，實施例1至3之聚酯瓶胚之△T與紅外線吸收粉體的中值粒徑呈反向關係。於實施例1之紅外線吸收粉體之中值粒徑為53nm，而實施例1之聚酯瓶胚之△T為12.04℃。於實施例2之紅外線吸收粉體為112nm，而實施例2之聚酯瓶胚之△T為11.13℃。於實施例3之紅外線吸收粉體為1.34μm，而實施例3之聚酯瓶胚之△T已降為9.72℃。由此可說明當紅外線吸收粉體中值粒徑越小時，製得的聚酯瓶胚係具有越佳的溫升性。可見，聚酯瓶胚溫升性與所用的紅外線吸收粉體的中值粒徑呈反向關係。 As shown in Table 1, the ΔT of the polyester preforms of Examples 1 to 3 was inversely related to the median diameter of the infrared absorbing powder. The median diameter of the infrared absorbing powder of Example 1 was 53 nm, and the ΔT of the PET preform of Example 1 was 12.04 °C. The infrared absorbing powder of Example 2 was 112 nm, and the ΔT of the polyester preform of Example 2 was 11.13 °C. The infrared absorbing powder of Example 3 was 1.34 μm, and the ΔT of the PET preform of Example 3 had been lowered to 9.72 °C. This shows that the smaller the median particle diameter of the infrared absorbing powder, the better the temperature rise of the obtained polyester preform system. It can be seen that the temperature rise of the polyester preform is inversely related to the median diameter of the infrared absorbing powder used.
如表1所示，實施例1至3之聚酯瓶體之△L與紅外線吸收粉體的中值粒徑呈正向關係。於實施例1之紅外線吸收粉體之中值粒徑為53nm，而聚酯瓶體之△L為1.89。於實施例2之紅外線吸收粉體為112nm，而實施例2之聚酯瓶體之△L為2.57。於實施例3之紅外線吸收粉體為1.34微米，而實施例3之聚酯瓶體之△L已升為3.01。由此可說明紅外線吸收粉體中值粒徑越小時，製得的聚酯瓶體係具有越白的色澤。 As shown in Table 1, the ΔL of the polyester bottles of Examples 1 to 3 was positively correlated with the median diameter of the infrared absorbing powder. The infrared absorbing powder of Example 1 had a median diameter of 53 nm, and the polyester bottle had a ΔL of 1.89. The infrared absorbing powder of Example 2 was 112 nm, and the ΔL of the polyester bottle of Example 2 was 2.57. The infrared absorbing powder of Example 3 was 1.34 μm, and the ΔL of the PET bottle of Example 3 had risen to 3.01. This shows that the smaller the median particle diameter of the infrared absorbing powder, the whiter the color of the obtained polyester bottle system.
如表1所示，以聚酯母粒之重量為基準，實施例1、7及8之紅外線吸收粉體之含量分別為1wt%、10wt%及20wt%。實施例1、8及9之△T分別為12.04℃、11.80℃及11.77℃，而實施例1、8及9之△L分別為1.89、2.02及2.11。由此可說明當聚酯母粒所含有紅外線吸收粉體之含量越高，會使得母粒與第二聚酯於射出機內熔融混練 時，粉體不易分散均勻，除了使得所製得的聚酯瓶胚的吸收紅外線效果不彰，也會使得所製得的聚酯瓶體的△L值降低，即，使得所製得的聚酯瓶體的色澤偏黑。 As shown in Table 1, the contents of the infrared absorbing powders of Examples 1, 7, and 8 were 1 wt%, 10 wt%, and 20 wt%, respectively, based on the weight of the polyester master batch. The ΔT of Examples 1, 8 and 9 were 12.04 ° C, 11.80 ° C and 11.77 ° C, respectively, while the ΔL of Examples 1, 8 and 9 were 1.89, 2.02 and 2.11, respectively. It can be explained that when the content of the infrared absorbing powder contained in the polyester masterbatch is higher, the masterbatch and the second polyester are melted and kneaded in the injection machine. When the powder is not easily dispersed evenly, in addition to making the infrared absorbing effect of the prepared polyester preform unsatisfactory, the ΔL value of the obtained polyester bottle body is also lowered, that is, the obtained poly polymerization is obtained. The color of the ester body is black.
如表1所示，於實施例2、11、16及19之紅外線吸收粉體分別為摻雜有銫之三氧化鎢、摻雜有銫與氯之三氧化鎢、摻雜有銫與錫之三氧化鎢及摻雜有銫與銻之三氧化鎢。而實施例2、11、16及19之聚酯瓶胚之△T分別為11.13℃、11.44℃、10.61℃及11.14℃，且實施例2、11、16及19之聚酯瓶體之△L分別為2.57、2.68、2.81及2.91。由此可說明以此四種作為紅外線吸收粉體所製得的聚酯瓶胚及聚酯瓶體分別可具有良好的溫升性及色澤。 As shown in Table 1, the infrared absorbing powders of Examples 2, 11, 16 and 19 are respectively doped tungsten trioxide, antimony and chlorine doped tungsten trioxide, doped with antimony and tin. Tungsten trioxide and tungsten trioxide doped with antimony and antimony. The ΔT of the polyester preforms of Examples 2, 11, 16 and 19 were 11.13 ° C, 11.44 ° C, 10.61 ° C and 11.14 ° C, respectively, and the ΔL of the polyester bottles of Examples 2, 11, 16 and 19. They are 2.57, 2.68, 2.81 and 2.91 respectively. Therefore, it can be explained that the polyester preform and the polyester bottle body obtained by using the four kinds of infrared absorbing powders have good temperature rise and color, respectively.
基於上述，藉由以摻雜有銫之三氧化鎢、摻雜有銫與氯之三氧化鎢、摻雜有銫與錫之三氧化鎢及摻雜有銫與銻之三氧化鎢為紅外線吸收粉體，實施例1至19之紅外線吸收聚酯母粒係能令其所製得的聚酯瓶胚除了能具有良好的紅外線吸收性質以快速升溫並提高生產效率之優點外，由實施例1至19之聚酯瓶胚所製得的之聚酯瓶體之L值還能高達90以上，係具有較白的色澤，從而達到使人輕易辨識聚酯瓶體內的內容物及視覺感覺良好之優點。 Based on the above, infrared absorption is performed by doping tungsten trioxide doped with antimony, tungsten trioxide doped with antimony and chlorine, tungsten trioxide doped with antimony and tin, and tungsten trioxide doped with antimony and antimony. The powder, the infrared absorbing polyester masterbatch of Examples 1 to 19 can make the polyester preform prepared thereby have the advantages of good infrared absorption property to rapidly heat up and improve production efficiency, and the embodiment 1 The polyester bottle made of the polyester preform of 19 can still have an L value of more than 90, and has a white color, so that the content of the polyester bottle can be easily recognized and the visual feeling is good. advantage.
此外，在製作瓶體的最佳化上，取用中值粒徑約為50nm的紅外線吸收粉體，令紅外線吸收聚酯母粒所含有的紅外線吸收粉體為1wt%，並令紅外線吸收聚酯母粒所製得之聚酯瓶胚係含有100ppm至500ppm之紅外線吸收粉體，當可令該聚酯瓶胚含有最適之溫升性，且由該聚酯瓶胚所製得之聚酯瓶體當可具有最佳化的色澤。 In addition, in the optimization of the bottle body, the infrared absorbing powder having a median diameter of about 50 nm is used, so that the infrared absorbing powder contained in the infrared absorbing polyester masterbatch is 1 wt%, and the infrared absorbing polymer is absorbed. The polyester preform produced by the ester masterbatch contains 100 ppm to 500 ppm of infrared absorbing powder, and the polyester preform can contain the optimum temperature rise and the polyester obtained from the polyester preform The bottle body can have an optimized color.
