1288767 at B7 五、發明説明(1 ) 本發明係有關一種高汽油滲漏阻隔性塑膠摻合物容器之製備方 法,其包括以價廉之傳統吹瓶成型機使用摻加改質聚醯胺(MPA)的高 密度聚乙烯(HDPE)之適當配方,即PE/MPA組成物,經由積層吹瓶法 製程吹瓶製備得到在HDPE基質中形成MPA積層結構(laminar structure)之高汽油滲漏阻隔性塑膠摻合物容器。 汽油極易從容器滲透出來,目前貯存汽油所用容器(如一般貯裝 容器、及汽機車、汽船、割草機等所用油箱等)均多以價格低廉且兼 具優異加工性,物理及化學性質之高密度聚乙烯(HDPE)爲主要塑膠材 質。唯美中不足的是HDPE容器在貯存汽油時會嚴重滲漏。進而衍生 之環保、公安及因汽油滲透而造成資源大幅損耗問題。近年來,雖已 有成功運用多種技術來‘大幅改善其抗汽油滲漏之阻隔性者,比如,經 表面氟化(J.P Hobbs·,M. Anand. And B. A· Campion, in Barrier Polymer and Structures, W. J. Koros Ed., Chapter 15, American Chemical Society, Washington (1990))或磺化處理(W. E.Walles,in Barrier Polymer and Strutures, W. J.

INSTRUCTION DESCRIPTION (1) The present invention relates to a method for preparing a high gasoline leakage barrier plastic blend container, which comprises using a modified polyamine (in the form of a cheap conventional blow molding machine) MPA) high-density polyethylene (HDPE), the proper formulation of PE/MPA composition, is prepared by a laminating bottle blowing process to obtain high gasoline leakage barrier properties for forming a MPA laminar structure in HDPE matrix. Plastic blend container. Gasoline is easily infiltrated from the container. At present, the containers used for storing gasoline (such as general storage containers, fuel tanks for steam locomotives, steamboats, lawn mowers, etc.) are mostly inexpensive and have excellent processability, physical and chemical properties. High density polyethylene (HDPE) is the main plastic material. The only drawback is that HDPE containers can leak heavily when storing gasoline. Further, environmental protection, public security, and the loss of resources caused by gasoline penetration have been caused. In recent years, there have been successful attempts to use a variety of techniques to 'substantially improve their resistance to gasoline leakage, such as surface fluorination (JP Hobbs, M. Anand. And B. A. Campion, in Barrier Polymer and Structures, WJ Koros Ed., Chapter 15, American Chemical Society, Washington (1990)) or sulfonation (WEWalles, in Barrier Polymer and Strutures, WJ Koros Ed., Chapter 14,. American Chemical Society Washington (1990)) HDPE and Multi-layer coextrusion laminar blowing method (S· Willian, Chemtech August 481 (1988)), etc., but the surface treatment method has process hazard, high pollution, and high investment cost. And the disadvantages of difficult recycling of waste materials; multi-layer co-extrusion method has the disadvantages of complicated blow molding machine, high investment cost, high investment cost and difficult recycling of waste. Compared with the above two technologies, the laminated blowing method, in addition to the shortcomings of the above-mentioned technology, has a simple processing (a conventional PE bottle forming machine can be used), the waste can be recycled and reused, and the investment cost is lower than the above two methods. And so on, so it is widely favored by the container molding industry, and has developed rapidly in recent years. The technique of the layered method is extremely high, and it is necessary to effectively control the lamellar layer of Lamamine to grow in parallel, and to use DuPont's patented, specially designed and expensive blow molding machine. Its concept layer was first revealed in Taiwan Polymerization Corporation ((Taiwan Polymerization Chemical Co., Ltd.), Central Standards Bureau of the Ministry of Economic Affairs, Patent No. 53,999 (1992)) and Du Pont (RC·Diluccio, US· Patent 4,416,942 (1983); VK Mehra, US Page 1 of 13 This paper scale applies to China National Standard (CNS) A4 specification (210X297 mm) (please read the notes on the back and fill in the form)

Only PA is incompatible with PE, and the interface is not well connected. It is often necessary to add CP to PE/PA during the blow-molding process to increase its interface with HDPE. In view of this, the inventor of the present invention discovered through the intensive research that in selecting the appropriate CP and PA, the modified nylon (MPA) was first made by twin-screw extruder, and the PE was properly formulated with MPA. A blow molding machine can be used to prepare PE/MPA blending bottles. The prepared bismuth/MPA blending bottle can achieve a high gasoline permeation barrier effect, and only uses a conventional inexpensive blow molding machine, which is not only cost-effective but also infringes on existing domestic and foreign related patents. And the resulting gasoline leakage barrier effect can be as low as 5% or less of the total stored gasoline in the container at 40 ° C for one year. This barrier effect is higher than the barrier leakage effect of the above patents. Accordingly, the present invention provides a method for preparing a high gasoline leakage barrier plastic blend container comprising using a high density polyethylene blended with modified polyamine (MPA) in a conventional blow molding machine at a low cost ( HDPE) A properly formulated, ie, PE/MPA composition, is prepared by a laminating bottle blowing process to obtain a high gasoline leakage barrier plastic blend container that forms a MPA laminar structure in a HDPE matrix.

The polyamine used is Nylon 6, also available from Taiwan Chemical Fiber Co., Ltd. under the trade name Sunylon 6N. Polyethylene used in the examples (HDPE Taiso) x 9003) and antioxidants (Irganox B225) were obtained from Formosa Plastics Co. and Ciba_Beigy, respectively. Prior to melt blending, PA and CP were dried at 80 ° C for 16 hours and at 60 ° C for 8 hours. About 1500 ppm of antioxidant and dry PA/CP component were dry blended in a weight ratio of 85:15, and then fed into an Ekegai PCM 45 co-rotating twin-screw extruder to make MPA resin. The extruder was placed in the feed zone. The 220 ° C is operated at a screw speed of 100 rpm toward the extrusion die at 240 ° C. The CP modified polyamine of the twin screw extruder is quenched in cold water at about 15 ° C and Cut into nine forms. The various modified polyamido nine particles were dried at 80 ° C for 16 hours and then dry blended with PE at a weight ratio of 10:90. The mixed PE/MPA and PE/PA blends were then blow molded in a Jonh Huah TPH-550 extrusion blow molding machine at an extrusion temperature of 230 ° C and a screw temperature of 400 rpm. The ruthenium/MPA blend was extruded using a conventional polyethylene screw prior to blow molding. The blow molded bottle weighs about 100 grams and has a wall thickness of about 750 milliliters and a capacity of about 2 millimeters. For comparison purposes, also the basic PE resin used the same screw and blow molding machine, but operated at a backlog temperature of 190 ° C and a screw speed of 400 rpm. The above-made bottles, such as blown into PE, PE/PA and PE/MPA, are annealed at different temperatures for different periods of time. The annealing temperatures used were 60, 70, 80, 90, 100 and 120 °C, respectively. The bottles were annealed for 1, 2, 4, 8, 16, 24 and 36 hours, respectively, at each annealing temperature. Table 1 summarizes the heat treatment conditions used and the sample numbers for PE, PE/PA and PE/MPA bottles.

INSTRUCTIONS (10) The penetrant test evaluates the weight loss of the gasoline contained in the measuring bottle, such as blow molding into bottles and annealed bottles. PE, PE/PA and PE/MPA bottles are loaded with 380 grams of gasoline at the beginning. The weight loss of the gasoline was determined after the bottle was placed at 40 ° C for 14 days. On the other hand, the osmotic barrier properties of PA and MPA resins were also determined based on hot press sheets. The PA and MPA dry pellets were hot pressed into a sheet of about 2 mm thick and cut into discs of 14 cm diameter. Round PA and MPA sheets were capped on top of a test flask containing 250 passengers of gasoline. Then, the flask was placed at 40 ° C for 14 days' to measure the osmotic barrier properties of the wafer. The gasoline permeability of each bottle or hot plate is estimated based on the average permeability of at least three bottles or hot plate samples, respectively. Gasoline fuel composition before and after the permeation test The composition of the unleaded gasoline fuel was determined before and after the bottle penetration test using a China 8900 gas chromatograph (GC) equipped with a hydrogen flame free detector. The Restek Alumina Plot capillary column was used to separate the methanol/gasoline fuel. The capillary has an inner diameter of about 0.53 mm and a length of 30 meters. The gasoline fuel was injected into the GC at 230 ° C before and after the penetration test to determine the composition. Helium at 20 cm 3 /min was used as a carrier gas at 220 °C. In order to improve the separation efficiency, the capillary was raised from 30 ° C to 210 t at a heating rate of 4 ° C / min. The detector temperature is 230 °C. The main components contained in unleaded gasoline are non-polar linear, cyclic and aromatic hydrocarbons (about 5 to 10 carbons) and certain polar liquids such as acetone, ethanol, and other additives. For comparison and convenience, select hydrocarbon components (ie, n-pentane, xylene, and decahydro) and polar components (ie, acetone and ethanol) with 5 to 10 carbon backbones in gasoline fuel and determine by GC. The residual weight % represents the residual gasoline fuel composition after the penetration test. The residual weight % of each solvent was determined by the ratio of the area of each solvent after the penetration test to the area ratio of each solvent peak before the penetration test. Thermal Properties Page 10 of 13 This paper scale applies to China National Standard (CNS) A4 specification (210X297 mm) (Please read the note on the back and fill out this page) Printed by the Intellectual Property Office of the Ministry of Economic Affairs 1288767 at B7 V. INSTRUCTIONS (fl) (Please read the note on the back and fill out this page). For PE, PE, PA and PE/MPA bottles, PE, PA, CP and MPA have thermal properties. The Pont 2010 differential scanning calorimeter (DSC) was measured separately. All scans were carried out at a heating rate of 10 ° C/min under a nitrogen flow rate of 25 ml/min. The instrument was calibrated with pure indium. A sample weighing approximately 15 mg was placed in a standard aluminum sample pan. The baseline from 30 ° C to 160 ° C and the complete heat of fusion of 293 Joules / gram of PE were used to calculate the crystallinity of pE and CP. The crystallinity of PA or MPA contained in PE/CP/PA and PE/MPA was estimated using a baseline of 170 to 250 t and a total melting heat of 190 Joules/g. The baselines used in the experiments were adjusted to have a maximum fluctuation of less than 〇.〇4 mw 03⁄4 within the target temperature range. When using these baselines, the maximum variation in heat of fusion is typically around ±3 J/g, which results in a 1% error in estimating crystallinity. For example, the shape of blown bottles and annealed bottles. To observe the individual deformation configurations of MpA and PA resins contained in blown and annealed ΡΕ/PA and PE/MPA bottles, first cut these bottles with a scalpel. After that, engraved with uranyl formate. The etched samples were then plated with gold and examined using a Joel TSM-5200 scanning electron microscopy (SEM). For comparison purposes, etched samples such as blow molded bottles and annealed bottles were also examined by SEM. Results The Ministry of Economic Affairs, Intellectual Property Bureau, Staff and Consumers Cooperatives printed PE, PA, CP and MPA hot-pressed sea PE, PE/PA and PE/MPA, such as the late plastic bottle, the gasoline leaking parts, Table II, listed PE, PA, Gasoline permeability of CP and MPA hot pressed tablets. Among the three matrix resins, namely PE, CP, and PA, the PA sheet exhibited the best resistance to gasoline penetration, while the CP sheet exhibited the worst resistance to gasoline leakage. Poly-polyamine (MPA) tablets showed a better resistance to gasoline leakage than PA tablets. The gasoline permeability of MPA is about 49 times and 7 times slower than that of PE and PA sheets (see Table II). Similar to the results obtained by hot pressing, PE, PE/PA and PE/MPA bottles, such as blown PE bottles, have the worst gasoline penetration.

As shown in Table II, after incorporation of PA or MPA in PE during blow molding, gasoline penetration resistance can be greatly improved, and the barrier improvement order corresponds to the improved barrier sequence of the barrier resin in PE. . After adding 10% by weight of "People or PA" in PE, the gasoline permeability of blown PE/MPA or PE/PA bottles such as blown PE bottles is about 130 times or 15 times slower respectively. After annealing PE, The gasoline leakage of PE/PA and PE/MPA bottles is quite surprising. After annealing the PE bottles at 60 to 120 °C for different time, the gasoline penetration rate has increased significantly. (See Figure 1.) In fact, their gasoline permeability increases consistently with annealing temperature and time. For example, 'PE bottles that are annealed at 120 °C for 32 hours have gasoline penetration rates such as blown PE bottles. Approximately 30% faster. Similarly, when PE/PA bottles are annealed at 90 ° C or higher, the gasoline permeation rate also increases significantly with annealing temperature and time (see Figure 2). However, PE/PA bottles are in When the temperature is annealed at 60 ° C for various times, the permeation rate is slightly reduced. After the bismuth/MPA bottle is annealed at 120 ° C for 32 hours, the gasoline permeation rate such as blown PE / MPA bottle is reduced by about 32%, which is equivalent to The blown PE bottle and the corresponding annealed PE bottle are about 190 times and 240 times slower respectively. For example, blow molding and bonfire PE, PE/PA and PE/MPA bottles Figure 4 shows a typical photomicrograph of the ruptured surface of PE, PE/PA and PE/MPA bottles. It can be seen that many well-defined MPA layers are in the PE matrix. For example, the wall thickness of the blown PE/MPA bottle is distributed (see Figure 4c). A slightly broken but less clear PA layer can be seen on the ruptured surface of a blown PE/PA bottle (see Figure 4b). It is inferred that the improvement level of PE/MPA and PE/{A bottle is obviously determined by the barrier properties of the matrix barrier resin. Furthermore, the segmentation of the clear and elongated MPA layer can extend the barrier period of the permeation molecule and improve the PE/MPA. The gasoline penetration resistance of the bottle. Conversely, it can be interesting to find that on the annealed pE 'ΡΕ/PA and PE/MPA bottles, no fracture surface morphology was observed relative to those such as blow molded bottles. Obviously page 12 of 13 This paper scale applies to China National Standard (CNS) A4 specification (210Χ297 mm) 1288767 at B7 V. Invention description (13) Change (see Figures 4d to 4f). It is speculated that the annealed PE, PE/PA and PE/MPA bottles have significant changes in gasoline penetration resistance. May not be a change in morphology from annealing. PE, PE/PA and PE/MPA bottles are hot parts. Figures 5a to 5c show in PE, PE/PA and PE/MPA bottles such as blown and annealed. The crystallinity of the contained PE is 値(Wc). At the indicated temperature, the crystallinity of the PE contained in the annealed bottle is higher than that of the blown bottle, and increases significantly with the annealing time. At the fixed annealing time, the Wc値 of the PE contained in the PE/PA and PE/MPA bottles after annealing PE will increase significantly with the increase of annealing temperature. As shown in Figures 5a to 5c, the Wc of the PE contained in the retort was increased by about 6 and 5% after annealing at 120 ° C for 32 hours, respectively. Gasoline fuel composition before and after the sputum test. Figures 6 to 8 show typical compositions of gasoline fuels such as blown bottles and annealed bottles before and after the penetration test. At 40 ° C, 14 days after the gasoline fuel contains hydrocarbon components with 5 to 10 main chain carbon atoms (such as n-pentane, toluene, dimethyl and decahydro), a significant amount will pass through, for example, a blow molded bottle. Polar components such as acetone and ethanol remain almost unchanged and have no penetration (see Figure 6). Conversely, after the barrier resin is incorporated into the PE matrix, the relatively non-polar hydrocarbon components contained in the gasoline fuel are significantly blocked during the penetration test without penetration, such as blown PE/MPA bottles such as blown PE/PA. The penetration of hydrocarbon components is more successfully blocked (see Figures 7 and 8). However, the amount of polar components (such as acetone and ethanol) that pass through, for example, blown PE/PA bottles and PE/MPA bottles is very small and is about to pass through, for example, blown PE bottles. It is quite surprising that the amount of penetration of both the non-polar hydrocarbon component and the polar component obtained by annealing the PE bottle is higher than that of a blown PE bottle; and it increases uniformly with annealing temperature and time (Fig. 6). As shown in Fig. 7, there is a similar tendency for PE/PA bottles which are annealed at 90 ° C or higher for different times. Conversely, after any annealing treatment of the PE/MPA bottle, the amount of penetration of both the relatively non-polar hydrocarbon component and the polar component decreases consistently with the annealing temperature and time (see Figure 8).
