Invention field

The present invention relates to a kind of method of producing moulded products from the transparent unmixability blend polymer that contains at least two kinds of polymeric constituents.More particularly, the present invention relates to the method that a kind of never miscible blends is produced transparent moulded products, described unmixability blend comprises: at least a thermoplastic polymer, the scrap stock polymkeric substance of the homogeneous blend of copolyamide or at least two kinds of polymeric amide and recovery is abrasive again.

Background of invention

Many products (particularly food) are responsive to the existence of oxygen and the loss or the absorption of water.Wrapped product with this susceptibility is the deterioration because be exposed to oxygen or moisture absorption easily.For example, being used for the wrapping material that limit food product contacts with oxygen can help to keep the quality of food article and reduce rotten.Therefore, the use of this barrier package keeps the longer usage period of goods, thereby reduces cost and the waste that stores again.For making, the effort that addresses this problem in wrapping material, is extensive use of oxygen obstruction agent and/or moisture barrier (protection against the tide) agent.Known many polymeric materials barrier agent of doing oxygen or moisture.For example, typical moisture barrier agent comprises polyethylene and polypropylene.Representational oxygen obstruction agent comprises polyethylene/vinyl base alcohol (" EVOH "), polyvinyl alcohol (" PVOH "), polymeric amide (nylon), and the blend of these materials.Polyvinylidene dichloride, vinyl chloride copolymer and vinylidene chloride/methyl acrylate copolymer are also as moisture and oxygen obstruction agent.

But these conventional barrier materials are expensive, and have unsettled constitutional features or other defective, only cause being difficult to by gas barrier material produce wrapping material or form unwanted wrapping material.For example, though EVOH has excellent oxygen barrier property, can not be used as the moisture barrier agent.It is disadvantageously expensive when other barrier material is used alone as wrapping material.For fear of these problems, use multilayered structure in the common practice in, wherein the amount of expensive barrier material can reduce to thin layer, and uses with the cheap polymkeric substance as structural sheet on the one or both sides of barrier layer.The use of multilayered structure also helps the protection barrier layer to avoid deterioration by structural sheet.But the production of multilayer product is expensive.In addition, multi-layer product is difficult aspect recycling, because different polymeric constituents is difficult to separate.In addition, polymkeric substance scrap stock or " grinding again " material that reclaims caused unsatisfied mist degree or opacity usually with the stock polymer blend, this is because the raw material and the uncompatibility of abrasive again.

The shortcoming of conventional barrier polymer also can overcome by the blend that uses barrier polymer and another kind of polymkeric substance.As mentioned above, disadvantageously, many blends of barrier polymer and other thermoplastic polymer are unmixability, and are opaque or muddy.These blends need to be applied to the purposes of the transparency, for example beverage container unsatisfactorily.

In packaging application, use polyester polymers, for example polyethylene terephthalate (" PET ") usually.PET has many performances that can be used for wrapping material, comprises for acceptable carbon dioxide barrier properties for the soft drink of packaging in having multiduty bottle.But, for in than bottle and the soft drink of in its oxygen obstruction agent, packing need improve the carbon dioxide barrier properties of PET, this barrier agent can not perform well in packing oxysensible product, for example beer, orange product, based on the product of tomato and the meat product of sterile packed.PEN (" PEN ") as barrier agent doubly than the effective 3-10 of PET, but more expensive.

Multilayered structure can be used to improve the gas-barrier characteristic of PET.The polymkeric substance that for example has excellent oxygen-barrier property (being also referred to as " passive obstruct ") or removing performance (being also referred to as " initiatively intercepting ") can make up with PET, makes the laminate structures of being made up of each single kind polymkeric substance.But the production of these multilayered structures is expensive.The blend of barrier polymer and PET also has been used to improve the oxygen barrier property of packing, but as mentioned above, has the poor transparency usually, and be not suitable for many packaging application.The transparency difference of blend also makes the production scrap stock that are difficult to autohemagglutination compound blend in future be recycled in the stock polymer.

(" EBM ") bottle of copolyester film and extrusion-blown modling need have toughness usually, and replaces PET to be used for extrusion-blown modling and film purposes usually.These purposes usually need with orientation PET comparable barrier property.But unfortunately, the barrier property of copolyesters is poorer than orientation PET.Multilayered structure can be by being coextruded to the center of thicker body construction to improve overall barrier with thin barrier films.But for the purpose of economy, EBM and membrane process require the abrasive again (being scrap stock) of high-content (the highest by 80%) to reprocess usually.Unfortunately, typical barrier material can not be miscible with copolyesters, and the blend of these barrier polymer and polyester shows the transparency of high-caliber mist degree and difference usually.So when being recycled initiation layer, the mist degree of whole membrane structure is increased to unacceptable level when scrap stock polymkeric substance (promptly abrasive) again.

Can provide good passive and/or initiatively barrier property, economical and effectively the round-robin blend polymer be that this area is needed.These blends should be transparent, contain thermoplasticity and barrier polymer (this polymkeric substance can provide the high barrier to oxygen, water and carbonic acid gas), and can use economically in the product forming process of abrasive introducing high-content again.In addition, need barrier and thermoplastic polymer composition, it can be used to produce the multi-layer product with high transparent economically, and can tolerate high-load abrasive again.
