Abstract
The invention relates to a composite film. The composite film is of a three-layer structure which comprises a polyethylene resin layer, an ethylene and vinyl alcohol copolymerization layer and a nylon layer in turn; the polyethylene resin layer and the ethylene and vinyl alcohol copolymerization layer are bonded through a polyethylene adhesive; the ethylene and vinyl alcohol copolymerization layer and the nylon layer are bonded through an adhesive.
Description
Technical field
The present invention relates to plastic sheeting field, particularly relate to a kind of composite membrane.
Background technology
Corona matt film is used for printing, compound, be mainly used in being attached on the body of packing box surface or can bottle, existing matt film generally comprises polyethylene layer, described polyethylene layer upper surface is provided with extinction layer, and extinction layer is formed by iron tyre compacting, but the matt film of this structure is non-watertight and heat resistance is poor, fragile in wet condition, when running into high temperature, yielding, thus its scope of application is restricted.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of composite membrane, in wet condition, not fragile, also not easily produce distortion when running into high temperature, the scope of application is extensive.
A kind of composite membrane, described composite membrane is three-decker, be followed successively by polyvinyl resin layer, ETHYLENE-VINYL ALCOHOL COPOLYMER layer and nylon layer, bonding by polyethylene adhesive between polyvinyl resin layer and ETHYLENE-VINYL ALCOHOL COPOLYMER layer, bonding by adhesive between ETHYLENE-VINYL ALCOHOL COPOLYMER layer and nylon layer.
Preferably, in described ETHYLENE-VINYL ALCOHOL COPOLYMER layer, the ratio of ethene and vinyl alcohol is 2:3.
Preferably, the Thickness Ratio of described polyvinyl resin layer, ETHYLENE-VINYL ALCOHOL COPOLYMER layer and nylon layer is 1:5:1.
Beneficial effect: this composite membrane has splendid heat sealability, melting behaviour, physical and mechanical property, has superpower block water gas barrier properties and excellent chemical-resistant stability, can be compatible with five kinds of solution, has good compatibility.
This invention scope of application is quite extensive, except being applied to space station, can also apply the storage of the oil of the industries such as oiling work, nuclear power and waste water, transport and collection etc.
The general tank in the space station adopting this composite membrane to make has the advantages such as lightweight, collapsible, Adaptability of medium is strong.
This composite membrane processing performance is good, is easy to the hold-up vessel being made into all kinds of solution.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Wherein, 1--polyvinyl resin layer, 2--polyethylene adhesive, 3--ETHYLENE-VINYL ALCOHOL COPOLYMER layer, 4--adhesive, 5--nylon layer.
Specific embodiments
As shown in the figure, a kind of composite membrane, described composite membrane is three-decker, be followed successively by polyvinyl resin layer 1, ETHYLENE-VINYL ALCOHOL COPOLYMER layer 3 and nylon layer 5, bonding by polyethylene adhesive 2 between polyvinyl resin layer and ETHYLENE-VINYL ALCOHOL COPOLYMER layer 3, ethene-vinyl alcohol is bonding by adhesive 4 between totally 3 poly layer and nylon layer 5.
Preferably, in described ETHYLENE-VINYL ALCOHOL COPOLYMER layer 3, the ratio of ethene and vinyl alcohol is 2:3.
Preferably, the Thickness Ratio of described polyvinyl resin layer 1, ETHYLENE-VINYL ALCOHOL COPOLYMER layer 3 and nylon layer 5 is 1:5:1.
In sum, this composite membrane has splendid heat sealability, melting behaviour, physical and mechanical property, has superpower block water gas barrier properties and excellent chemical-resistant stability, can be compatible with five kinds of solution, has good compatibility.
This invention scope of application is quite extensive, except being applied to space station, can also apply the storage of the oil of the industries such as oiling work, nuclear power and waste water, transport and collection etc.
The general tank in the space station adopting this composite membrane to make has the advantages such as lightweight, collapsible, Adaptability of medium is strong.
This composite membrane processing performance is good, is easy to the hold-up vessel being made into all kinds of solution.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
