Abstract
The invention discloses a preparation method of a high-transparency nylon composite film, belonging to the field of high polymer materials. According to the preparation method, polypropylene or a polypropylene elastomer is added into nylon resin as a high-transparency material so as to obtain a high-transparency nylon-coextruded composite film. The preparation method comprises the steps of: adding 1-5w% of the polypropylene or 0.5-1.5w% of polypropylene elastomer and silicon oil into the nylon resin; pouring into a high-speed agitator; mixing evenly and then adding into a nylon layer plastic extruder of multilayer coextrusion film blowing equipment; carrying out extrusion film blowing by the nylon layer plastic extruder and other layers of plastic extruders of the multilayer coextrusion film blowing equipment; and cooling and rolling to obtain the required high-transparency nylon composite film. According to the preparation method, the transparency of the prepared nylon composite film is improved while the barrier property is not influenced, so that the visibility of packaged commodities is increased.
Description
Technical field: the invention belongs to field of high polymer material processing, relate to the preparation method of a kind of high transparent nylon laminated film (sheet), the preparation method who particularly produces multilayer copolymerized compound membrane (sheet) with polypropylene or olefin type elastomer and nylon blending.
Background technology: in recent years, the functional film packaging material of developing high added value have energetically become the development trend of countries in the world plastic package material.Functional film has higher technology content usually, also has the favorable economic benefit and the stronger market competitiveness simultaneously, therefore enjoys people to pay close attention to.At present industrialization and in packaging field significant functional package film barrier packaging film, shrink film, surface protection film are arranged, are prone to Kaifeng film, antistatic film, antirust film, antibacterial film, degradable film etc.; The functional package film is the important kind of packaging material; The indispensable material of a little particular envelope has crucial status in plastic package material often.Wherein nylon/polyethylene (polypropylene) multi layer coex composite membranes (sheet) has become a kind of new packaging material with fastest developing speed in the plastic package material of countries in the world; This laminated film (sheet) is because its resistance oxygen that has; The function of steam blocks water; At meat product, grain and food, packaging fields such as electronic product have obtained extensive use.And because the feature of environmental protection of this production technology, the production of this type laminated film (sheet) has in recent years also obtained development faster in China.
Along with the progress of society, the packing of commodity has also been proposed increasingly high requirement, except the function that requires to pack, also require visual good after the commodity packaging, people can be accurate, clearly sees the actual state of commodity clearly, especially high-grade goods.This just requires coex composite membranes (sheet) having resistance oxygen, outside the function of the steam that blocks water, also will have the good transparency.
Multi-layer co-extruded film; Can be together with various homogenous material combination of advantages; Overcome the homogenous material shortcoming, obtain the film of excellent performance, like 5 layers of coextruded film; LDPE/ adhesive layer/PA6/ adhesive layer/LDPE, it has the obstruct steam property of barrier properties for gases, the ldpe film of nylon film, comprehensive good laminated film such as heat sealability is good, mechanical property is high, paracentesis resistance, resistance to low temperature are good concurrently.
Multi-layer co-extruded technology directly adopts plastic pellet more than three kinds or three kinds as raw material; After making every kind of plastics fusion plastification respectively through several extruders; Infeed simultaneously in the secondary mouthful mould and (perhaps pass through distributor; Infeed a mouthful mould after the plastics that each extruder is supplied with converge), close the film extrusion base at annular head internal exchange, through blowing, cooling and shaping and make multi-layer co-extruded laminated film.
Summary of the invention: the preparation method who the objective of the invention is to propose a kind of high transparent nylon laminated film (sheet).
The present invention adds in the nylon resin as a kind of material of enhancing the transparency with polypropylene or olefin type elastomer, thereby the nylon co-extrusion that makes the high grade of transparency goes out laminated film (sheet).
The present invention realizes like this: polypropylene or olefin type elastomer are added in the nylon resin by the percentage 1-5% of nylon resin weight and the silicone oil of nylon resin percentage by weight 0.5-1.5%; Pour homogenizer into; Fully behind the mixing; Be added in the nylon layer plastic extruder of multi-layer co-extruded blown film equipment, plastify simultaneously with the bonding resin layer plastic extruder of multi-layer co-extruded blown film equipment and polyethylene layer plastic extruder and extrude blown film, cooling; Rolling makes required high grade of transparency nylon laminated film.
Usually, polypropylene according to the invention is the polypropylene of random copolymerization; Said olefin type elastomer is density 0.89g/cm
3-0.91g/cm
3Olefines spring part in the scope.
The multi-layer co-extruded blown film equipment that the present invention adopts, the multi-layer co-extruded equipment more than three layers or three layers of being generally is as the making apparatus of film.
Among the preparation method of the present invention, silicone oil is as coupling agent.
The present invention adopt usually lower blowing water cold process production technology that this field knows or on blow in the cold process production technology.
The nylon laminated film of the inventive method preparation has improved the transparency of film under the situation that does not influence barrier, thereby improves the visuality of package goods.
The specific embodiment: the present invention is described in detail below in conjunction with embodiment
