Description
Technical field
Metallized film technical field is the utility model is related to, more particularly to a kind of special zinc-aluminium composition metals of LED gather
Ester film.
Background technology
Metal is melted under high vacuum state, evaporates, be deposited on basement membrane, one layer of very thin gold is formed in membrane surface
The plastic sheeting belonged to after layer is exactly metalized film.Metallized film capacitor is to do medium with organic plastics film, thin to metallize
Film does electrode, and electric capacity made of (except lamination) is made by winding method, thin used in metallic film capacitor
Film has poly- ethyl ester, polypropylene, makrolon etc., in addition to convoluted, also there is lamination-type.Wherein with polyester film medium and poly- third
Alkene film medium is most widely used, but the major defect of metalized film is poor for tolerance high current ability, and this is due to metalized film
Layer is thinner than metal foil a lot, and carrying high current ability is weaker.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of special zinc-aluminium composition metal polyester films of LED.
The utility model adopts the following technical scheme that：
A kind of special zinc-aluminium composition metal polyester films of LED, including polyester base film layer, the polyester base film layer surface are coated with
Zinc-aluminium composite bed, the side on the zinc-aluminium composite bed be provided with thickened area, and the thickened area includes some being interweaved in length and breadth
Barrier layer, the cross section of the barrier layer is circle, and the barrier layer is combined by polyvinyl alcohol and polythene material, described
The Surface coating of barrier layer has insulating barrier, and the insulating barrier is made up of chloroprene rubber material, and the intersection of the barrier layer is provided with
Enhancement layer.
Preferably, elasticity layer is wrapped up on the enhancement layer, plasticizer is added with the elastic layer.
Preferably, the plasticizer is phthalic acid lipid plasticizer.
Preferably, the surface of the insulating barrier is provided with high-temperature-resistant layer.
Preferably, the high-temperature-resistant layer is made up of polyimide material.
Preferably, the polyethylene is LLDPE.
The utility model has the advantages that:This is adopted using the new special zinc-aluminium composition metal polyester films of LED
The barrier layer and enhancement layer being interweaved in length and breadth are added used in thickened area, it is good can make it that whole metalized film has
Tensile strength, durability improve.

In figure mark for:1st, polyester base film layer；2nd, zinc-aluminium composite bed；3rd, thickened area；4th, barrier layer；5th, insulating barrier；6th, add
Strong layer；7th, elastic layer；8th, high-temperature-resistant layer.
Embodiment
As shown in Figure 1 to Figure 2, it is a kind of special zinc-aluminium composition metal polyester films of LED of the present utility model, including polyester
Base membrane layer 1, the surface of polyester base film layer 1 are coated with zinc-aluminium composite bed 2, and the side on zinc-aluminium composite bed 2 is provided with thickened area 3, thickened area 3
Including some barrier layers 4 being interweaved in length and breadth, the cross section of barrier layer 4 is circle, and barrier layer 4 is by polyvinyl alcohol and polyethylene
Material cladding is made, and as preferable, polyethylene is LLDPE, and LLDPE has preferably rule
Whole property and heat sealability.The laminated film has excellent air-tightness, certain moisture resistance, good heat sealability.Barrier layer 4
Surface coating has insulating barrier 5, and insulating barrier 5 is made up of chloroprene rubber material, and the intersection of barrier layer 4 is provided with enhancement layer 6.Enhancement layer
Elasticity layer 7 is wrapped up on 6, plasticizer is added with elastic layer 7.Plasticizer is phthalic acid lipid plasticizer, can be made whole
The pliability increase of individual enhancement layer.The surface of insulating barrier 5 is provided with high-temperature-resistant layer 8.High-temperature-resistant layer 8 is made up of polyimide material.
This uses to add in thickened area and is interweaved in length and breadth using the new special zinc-aluminium composition metal polyester films of LED
Barrier layer 4 and enhancement layer 6, can cause whole metalized film that there is good tensile strength, durability improves, also simultaneously
Have good barrier and heat resistance concurrently.
Specific embodiment of the utility model is these are only, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, to solve essentially identical technical problem, essentially identical technique effect is realized, it is made
Simple change, equivalent substitution or modification etc., are all covered by among the scope of protection of the utility model.
