Description
本发明涉及一种聚乙烯/聚对苯二甲酸乙二醇酯合金型单层阻隔包装材料，这种包装材料具有阻隔氧气，水蒸汽及二氧化碳功能的高分子共混材料。The invention relates to a polyethylene/polyethylene terephthalate alloy single-layer barrier packaging material, which is a polymer blend material with the function of blocking oxygen, water vapor and carbon dioxide.
目前，国内外用于食品、饮料、医药和日化用品等商品销售包装阻隔材料中，有阻隔性好的纯高分材料，如聚对苯二甲酸乙二醇酯，聚偏二氯乙烯，聚酰胺和聚乙二醇等，还大量使用聚对苯二甲酸乙二醇酯或聚酰胺与聚乙烯多层复合材料，如膜、袋等。纯高分子阻隔材料，因成本高，加工困难，仅用于付加值高的商品包装，多层复合材料是聚乙烯薄膜与聚对苯二甲酸乙二醇酯或聚酰胺薄膜复合而成，或通过共挤出方法生产制得，但因生产成本高，废旧品不能回收而限制了生产发展。Prasad Sambaru and S.A.Jabarin，Polymer Engineering and Science，33(13).P827报导了用马来酸酐接枝聚乙烯作为增容剂，研究了聚对苯二甲酸乙二醇酯/高密度聚乙烯共混物的力学性能、光学和热性能，结果表明该增容剂增容的聚对苯二甲酸乙二醇酯/高密度聚乙烯共混物有促进取向硬化作用，随着取向作用的增强，共混物的物理性能有所改善，但这种共混物是以对苯二甲酸乙二醇酯为主，加入少量聚乙烯共混，而且只是作理论性探讨，未用作阻隔材料的研究。席世平等高分子材料科学与工程No5 1994.P81，报导了用双螺杆挤出机反应性挤出的方法合成了低密度聚乙烯接枝马来酸镧离聚物，并将离聚物与对苯二甲酸乙二醇酯/低密度聚乙烯在双螺杆挤出机内熔融共混挤出，测定了聚对苯二甲酸乙二醇酯/低密度聚乙烯在注射标准试样的力学性能，发现离聚物有显著的增韧效果。但这种共混材料只增韧而不增强，也未用作阻隔材料的研究。At present, among the barrier materials used in the packaging of food, beverage, medicine and daily chemical products at home and abroad, there are pure high-grade materials with good barrier properties, such as polyethylene terephthalate, polyvinylidene chloride, poly Amide and polyethylene glycol, etc., also use a large number of polyethylene terephthalate or polyamide and polyethylene multilayer composite materials, such as films, bags, etc. Pure polymer barrier materials are only used for high value-added commodity packaging due to high cost and difficult processing. Multilayer composite materials are made of polyethylene film and polyethylene terephthalate or polyamide film, or It is produced by co-extrusion method, but the development of production is limited due to the high production cost and the inability to recycle waste products. Prasad Sambaru and S.A.Jabarin, Polymer Engineering and Science, 33(13).P827 reported the use of maleic anhydride grafted polyethylene as a compatibilizer, and studied the blending of polyethylene terephthalate/high-density polyethylene The mechanical properties, optical and thermal properties of the material show that the compatibilizer-compatibilized polyethylene terephthalate/high-density polyethylene blend can promote orientation hardening. With the enhancement of orientation, a total of The physical properties of the blend have been improved, but this blend is mainly based on ethylene terephthalate, blended with a small amount of polyethylene, and it is only for theoretical discussion and has not been used as a barrier material. Xi Shiping, Polymer Material Science and Engineering No5 1994.P81, reported the synthesis of low-density polyethylene grafted lanthanum maleate ionomer by reactive extrusion of twin-screw extruder, and combined ionomer with Polyethylene terephthalate/low-density polyethylene was melt-blended and extruded in a twin-screw extruder, and the mechanical properties of polyethylene terephthalate/low-density polyethylene in injection standard samples were measured , found that the ionomer has a significant toughening effect. But this kind of blended material is only toughened but not reinforced, and it has not been used as a research on barrier materials.
本发明的目的是针对现有技术的不足而提供一种聚乙烯/聚对苯二甲酸乙二醇酯合金型单层包装材料，其特点是将接枝聚乙烯增容剂与聚乙烯和聚对苯二甲酸乙醇酯共混制造合金粒料，这种合金粒料再与聚乙烯混合直接用于注射，挤出，中空和压延成型，生产出塑料薄膜、片、管、瓶和桶等阻隔材料制品，可以代替纯高分子材料和多层复合材料膜，不仅大幅度降低了成本，而且物理机械性能优于聚乙烯材料，有利于废旧制品的回收和三废治理。The purpose of the present invention is to provide a polyethylene/polyethylene terephthalate alloy single-layer packaging material for the deficiencies of the prior art, which is characterized in that the grafted polyethylene compatibilizer is combined with polyethylene and polyethylene Ethyl terephthalate is blended to produce alloy pellets, which are then mixed with polyethylene and directly used for injection, extrusion, hollowing and calendering to produce barriers such as plastic films, sheets, tubes, bottles and barrels.
