Abstract
The utility model discloses a flame-retardant polyester film. The ultraviolet-curing flame-retardant polyester printing ink comprises a UV ink bonding layer, an antistatic layer, a polyester upper surface layer, a flame-retardant polyester base layer and a polyester lower surface layer which are sequentially overlapped from top to bottom. The flame retardant property of the flame retardant polyester film of the utility model reaches UL94VTM-0 grade, and UV printing ink can be printed on the surface; the fireproof flame-retardant label has fireproof and flame-retardant performances and high cost performance, and is mainly applied to the fields of packaging and labeling of lithium batteries.
Description
Technical Field
The utility model belongs to the technical field of fire-retardant film, concretely relates to fire-retardant polyester film.
Background
Because the electronic and electric appliance industry attaches importance to and improves the flame retardant property requirement of the film, the common polyester film can not meet the safe use requirement, and the polyimide film has excellent flame retardant property, but is expensive and poor in die cutting property. The polyester flame-retardant film has the advantages of common PET films, excellent flame-retardant performance and electrical performance, higher added value, the thickness of the flame-retardant polyester film which is currently circulated in the market is more than 36 mu m, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem in the background art, the utility model provides a fire-retardant polyester film, fire behaviour reaches UL94VTM-0 grade, can be applied to fields such as lithium ion electronic packaging, label.
The utility model adopts the technical scheme as follows:
the utility model discloses a top layer under UV printing ink tie coat, antistatic layer, polyester upper epidermis, fire-retardant polyester basic unit and the polyester of superpose in proper order from top to bottom.
The thickness of the UV ink bonding layer is 3-4 mu m, the UV ink bonding layer is a water-based polyester layer, and the UV ink bonding layer is formed by specifically coating an Dongyuan MD-1245 product on an antistatic layer.
The antistatic layer is 0.1-0.2 mu m in thickness and is a water-based polythiophene layer, and is specifically formed by coating a Nantong Raffing chemical LS-2002N product on the upper surface of polyester.
The thickness of the flame-retardant polyester base layer is 25-30 mu m, and the flame-retardant polyester base layer is a phosphorus-containing copolyester ethylene terephthalate layer. The flame-retardant polyester base layer is prepared by blending and extruding characterized chemical fibers FG600 bright chips and Jinlibao R15 flame retardant.
The thickness of the polyester upper surface layer and the thickness of the polyester lower surface layer are both 2-3 mu m, and the polyester upper surface layer and the polyester lower surface layer are both PET layers containing micron-sized silicon dioxide. The upper polyester surface layer and the lower polyester surface layer contain micron-sized silicon dioxide, so that the flame-retardant polyester film has the property of easy opening. The polyester upper surface layer and the polyester lower surface layer are specifically prepared by extruding characterization chemical fibers FG600 large bright chips and characterization chemical fibers FG610 silicon dioxide master batches in an extruder.
The flame retardant property of the flame retardant polyester film reaches UL94VTM-0 level.
The flame-retardant polyester film is colorless and transparent or colored and transparent.
The utility model has the advantages that:
1) the utility model discloses have fire prevention fire-retardant performance, fire behaviour reaches UL94VTM-0 grade, and fire-retardant polyester film can reach 32 mu m minimum, has the high price/performance ratio.
2) The utility model discloses mainly be applied to packing, the label field of lithium cell.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the UV ink comprises a UV ink bonding layer (1), an antistatic layer (2), a polyester upper surface layer (3), a flame-retardant polyester base layer (4) and a polyester lower surface layer (5).
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, the utility model discloses a UV printing ink tie coat 1, antistatic layer 2, polyester top layer 3, fire-retardant polyester basic unit 4 and polyester bottom layer 5 of superpose from top to bottom in proper order. The UV ink bonding layer 1 is a water-based polyester layer, the antistatic layer 2 is a water-based polythiophene layer, the flame-retardant polyester base layer 4 is a phosphorus-containing copolyester ethylene terephthalate layer, and the polyester upper surface layer 3 and the polyester lower surface layer 5 are both ethylene terephthalate layers containing micron-sized silicon dioxide.
In specific implementation, the thickness of the UV ink bonding layer 1 is 3 μm; the thickness of the antistatic layer 2 is 0.2 μm; the thickness of the flame-retardant polyester base layer 4 is 30 μm; the polyester upper surface layer 3 and the polyester lower surface layer 5 each had a thickness of 3 μm.
The flame-retardant polyester film is yellow and transparent; the organic dye is easy to decolor, the color of the film is not easy to decolor through a preparation method of three-layer co-extrusion of the upper polyester surface layer 3, the flame-retardant polyester base layer 4 and the lower polyester surface layer 5, and the flame-retardant polyester film prepared through the three-layer co-extrusion method has good mechanical property because the mechanical strength of the flame-retardant polyester base layer is low. The antistatic layer 2 coated on the flame-retardant polyester base layer 4 makes the UV ink not easy to be stained with dust when being printed.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent transformations made by the contents of the specification are included in the patent protection scope of the present invention.
