Description
The present invention relates to a kind of imine colour fluorine film of multiple field, particularly scribble the colored multilayer formula film of pigment on film, the electric wire and cable that is used for motor is made winding material.
Kapton uses with other film or coating usually, plays the comprehensive function of each component.In the general multilayer architecture, internal layer is a polyimide layer, and the two sides all scribbles different fluoro-containing macromolecule materials, can play the high temperature resistant and anti-insulating materials that freezes.In order to distinguish different phase lines, to fluoro-containing macromolecule material, add pigment, and make colored plural layers, to satisfy the winding insulating barrier of electric wire and cable.In the United States Patent (USP) 4628003 disclosed high temperature hot melt bonding films, internal layer is a polyimide layer, its two sides is a kind of fluoro-containing macromolecule material layer, wherein contain 1～20%(weight ratio) disperse good inorganic pigment, for strengthening the cohesive force between polyimides internal layer and the fluorine carbon high polymer skin, between two-layer, there is α-chloromethyl phenyl trialkoxy silane (Alpha-chloromethylphenytrialkoxy silane) to do the bonding promotion.Therefore the skin of plural layers is fluoro-containing macromolecule materials of dyeing, and the look that presents sees unintelligible, not bright-coloured and transparency is relatively poor, also needs extraordinary silane compound to bond.
The objective of the invention is to provide a kind of imine colour fluorine film, and its internal layer is the polyimide film that contains pigment, and skin is a fluorine-containing polymer, look see from internal layer manifest and clear, bright-coloured, transparency is good, when making film, do not need to bond, just can satisfy the bonding requirement with extraordinary silane compound.
The present invention is a kind of imine colour fluorine film, the colored structural material of multiple field that is used for wound wire and cable, the electric insulation layer of continuous hot melt can be provided, comprise that internal layer is the painted polyimide film and the skin of fluorine-containing polymer, interior layer thickness is at 0.015～0.05 millimeter, contain 0.5～6%(weight ratio) high-temperature resisting pigment, outer layer thickness is at 0.01～0.03 millimeter, is that 300～340 ℃ hot melt fluorine-containing polymer is formed by fusing point.
Internal layer Kapton in the sandwich construction of the present invention is the heterocycle heat-resistant polymer that is synthesized in polar solvent by 44 ' diaminodiphenyl ether and pyromellitic acid anhydride.This Kapton has high temperature oxidation stability, electric insulating quality, still flexible and elasticity under cryogenic conditions also have non-flammability and radiation resistance, can closely be wrapped on the bare copper wire, in the application scenario of majority, Kapton should have 0.015～0.065 millimeters thick.
In the internal layer Kapton, select resistant to elevated temperatures pigment for use, require to have certain chemical stability, intermiscibility and dispersiveness with the heterocyclic imines group more than 300 ℃ the time as the pigment of colouring agent.Inorganic or the organic pigment of these high temperature that are suitable for is the green and northern tetracid acid anhydride of carbon black, titanium cyanines, and is black, green and purplish red to distinguish on the Kapton of internal layer.In internal layer Kapton structure on behind these pigment, all increased opacity, increase visibility for making the inner layer material of having gone up look, the consumption of pigment is 0.5～6%(weight ratio), be benchmark with the endothecium structure gross weight.Painted purpose is for electric wire and cable difference phase line.Required amount of pigment is generally the pigment coloring degree of depth and changes with the different of granularity, generally speaking, obtain visible look see need the 0.5%(weight ratio at least) consumption, yet consumption can have certain upper limit, as tangible increase consumption, can be influential to certain performance of polyimides in certain endothecium structure, so as long as reach the effect that certain identification color is seen, the performance that does not influence endothecium structure again is just passable.The granularity of pigment also has certain requirement, what present in polyamic acid resin because of pigment is slightly soluble, half molten state, thus also to run foul of each other by the thin pellet shot from a slingshot in the homogenizer, levigate pigment, reach 200 required order fineness, with the uniformity that guarantees that look is seen.
The shunting of internal layer Kapton of the present invention is painted very important, adopt rubbing method to satisfy required thickness every the dip-coating of the painted multiple tracks type of road formula, the general Kapton that adopts 4～5 road dip-coatings to make internal layer, painful Gardner viscosity 2～4 seconds, solid content is that 10～13% Kapton adds 0.5～6%(weight ratio in addition) pigment, the polyamic acid resin of dip-coating true qualities on the Kapton of internal layer at first, polyamic acid 2～3 roads of dip-coating band pigment again, outermost is the polyamic acid resin of one primary colors of dip-coating again, become painted Kapton with regard to dip-coating like this, pass through imidization again, peel off, pickling, the painted Kapton of finished product is finished in rewinding.
It is the hexafluoropropene about 0.2 micron and the copolymer of tetrafluoroethene that outer field fluorine-containing polymer recommends to select for use particle diameter, this is about 10～50%(weight ratio) hexafluoropropene, 50～90% tetrafluoroethene, to reach copolymer, make solid content in use and be 20～40% fluorine-containing polymer emulsion with complementary performance.Performance is more stable during the copolymer in the row scope in the use, can satisfy basic demand of the present invention.As a kind of function, when the sandwich construction of fluorine-containing polymer is wrapped on electric wire or the cable, the hot melting cohesion of reply polyimides internal layer is firm, the most effective when being 0.01～0.03 millimeter as the outer layer thickness of PUR, the thickness of recommending is 0.01～0.025 millimeter, the too thin meeting of adhesive film causes adhesion strength not enough, too thick hot molten time that then need be very long when the intensification hot melt, even can influence adhesion strength and electric property.
Imine colour fluorine film of the present invention, its internal layer is the Kapton that contains pigment, skin is the fluorine-containing polymer of primary colors, therefore look is seen and is manifested from internal layer, so clear, bright-coloured, very transparency might as well, when making film with this law, do not need to bond, just can satisfy the hot melt requirement with extraordinary silane compound.
