Description
The Copper Foil of used adhesive bonding agent when the present invention relates to make printing distributing board with the copper plating film plywood particularly relates to and has anti-vestige electric leakage (ト ラ
ッキ Application グ) the adhesive attachment Copper Foil that property and corrosion liquid resistance are good with binder layer.
Paper base material copper plating film plywood as the use of civil electric appliance printing distributing board, normally in the paper substrate plate dipping with resol and/or melamino-formaldehyde resin resinous principle as principal constituent, or thermosetting resin such as Resins, epoxy and the preforming material made in accordance with regulations the copper foil layer of the number of plies and application of adhesive gather into folds, heating and pressurizing is shaped and makes then.These copper plating film plywoods form conductor circuit by the etching Copper Foil, and the electrolytic coating of joint area is with punching or drilling method perforate, and sharp processing etc. is processed printing distributing board.
In recent years, along with the electrical equipment miniaturization, the distribution density of printed wiring uprises, the conductor graph thinning.And, when needing reflow soldering modes such as (リ Off ロ-ソ Le ダ-), adopt the operation that increases temperature when the installation of carrying out component and surface mounting.Corresponding to this densification, surface mountingization, then want conductor that high cohesive force is arranged to the copper plating film plywood, high solder thermotolerance etc. is arranged during installation.In order to satisfy these requirements, the tackiness agent that polyvinyl butyral resin, resol resin and Resins, epoxy are formed has carried out modification.
On the other hand, need apply in the high-tension purposes,, wish to use the strong copper plating film plywood of anti-vestige electric leakage property as the fire failure countermeasure at televisor etc.Yet the resol of above-mentioned tackiness agent is easy to cause the charing conducting, has the shortcoming of anti-vestige electric leakage property difference.Therefore, anti-vestige electric leakage property copper plating film plywood tackiness agent has been proposed, for example the spy opens flat 2-20584, Te Kaiping 1-282281, the spy opens clear 63-170482, the spy opens clear 63-154777 etc., and when having strong anti-vestige electric leakage property, cementability, solder thermotolerance also can roughly satisfy in practicality.
Yet former copper plating film plywood contain melamine formaldehyde resin in binder layer, so the acid resistance of binder layer is inferior for anti-vestige electric leakage property is provided.As everyone knows, melamino-formaldehyde resin is by acid attack, and debatable especially be when the etching that utilizes Copper Foil forms conductor circuit, be the resistivity of etching solution to cupric chloride-hydrochloric acid.At this moment, because binder layer is subjected to the corrosion of hydrochloric acid and soaking into of etching solution.The resistibility on surface reduces, and can cause the significant problems such as inhibition curing that cupric ion caused in the various resists that are coated on the binder layer.To this problem, proposed to utilize benzoguanamine modifications such as (ベ Application ゾ Network ア Na ミ Application) to solve, but reduced, so use it to have any problem owing to modification makes the performance of the binder materials of using as Copper Foil.
The object of the present invention is to provide a kind of usefulness to have and propose the equal above anti-vestige electric leakage property of tackiness agent with existing, and aspect solidity to corrosion the good coated adhesive attachment Copper Foil of tackiness agent.
Copper Foil with binder layer of the present invention, it is characterized in that in binder layer, containing and have the represented chlorinated isocyanurates of following general formula (1) (the resin of ring of ィ ソ シ ア ァ レ-ト), do not contain melamine formaldehyde (MF), more particularly, above-mentioned binder layer can be stipulated: have the resin 5-50 weight part of chlorinated isocyanurates ring, polyvinyl acetal resin 10-50 weight part, Resins, epoxy 5-40 weight part and blocked isocyanate resin 1-50 weight part.

Among above the present invention, have the resin of above-mentioned specific chlorinated isocyanurates ring, have high resistivity against fire, the binder layer that contains this resin also is difficult to worsen even fine discharge takes place when applying high-voltage, demonstrates high anti-vestige electric leakage property.Meanwhile, among the present invention owing to do not contain easily by the melamino-formaldehyde resin of acid attack, therefore in acid resistance, the excellent property aspect corrosion liquid resistance particularly.
As the resin that uses among the present invention with chlorinated isocyanurates ring, isocyanuric acid three-glycidyl ester (ト リ グ リ シ ジ Le ィ ソ シ ア ァ レ-ト), three-glycidyl three (2-hydroxyethyl) chlorinated isocyanurates, the carbamate compounds that the isocyanate trimerization reaction generates are arranged.These resins can also can more than 2 kinds and be used in a kind of independent use.As polyvinyl acetal resin, polyvinyl formal, polyvinylacetal are arranged, polyvinyl butyral acetal and their mixture.To the polymerization degree of polyvinyl acetal resin, there is no particular limitation for acetalizing degree etc.As Resins, epoxy, bisphenol A type epoxy resin is arranged, phenolic resin varnish type epoxy resin, O-cresols phenolic resin varnish type epoxy resin, halogenated epoxy resin etc., there is no particular limitation.These Resins, epoxy can also can more than 2 kinds and be used in a kind of independent use.As the blocked isocyanate resin, can adopt with blocks such as phenol, oxime, ethanol in polymeric polyisocyanate and the material that forms.
The cooperation ratio of each resin in the tackiness agent of the present invention is: resin 5-50 weight part, polyvinyl acetal resin 10-50 weight part, Resins, epoxy 5-40 weight part, blocked isocyanate resin 1-50 weight part with chlorinated isocyanurates ring, the resin 10-40 weight part that preferably has the chlorinated isocyanurates ring, polyvinyl acetal resin 20-50 weight part, Resins, epoxy 5-30 weight part, blocked isocyanate resin 5-40 weight part.When having resin less than 5 weight parts of chlorinated isocyanurates ring, can not improve anti-vestige electric leakage property, in case surpass 50 weight parts then cause the thermotolerance of copper plating film plywood to reduce.When polyvinyl acetal resin less than 10 weight parts, stripping strength significantly reduces, and goes if surpass 50 weight parts then be difficult to be dissolved in the tackiness agent paint vehicle.When Resins, epoxy less than 5 weight parts, the thermotolerance of copper plating film plywood, stripping strength reduce, if surpass 40 weight parts, stripping strength also can reduce.During blocked isocyanate resin less than 1 weight part, the thermotolerance of copper plating film plywood reduces, if surpass 50 weight parts, then the solvability in the tackiness agent paint vehicle is a problem.
These resin combinations are dissolved in the organic solvent modulating adhesive paint vehicle.About organic solvent,, but preferably use cheap organic solvent such as methyl alcohol, acetone, butanone, toluene so long as it is all right to dissolve the organic solvent of above-mentioned resin.
Copper Foil with binder layer of the present invention is by after above-mentioned tackiness agent paint vehicle is coated in Copper Foil alligatoring face, in the method for drying oven internal heating and make.
In the scope of the main aim of the present invention, also can in tackiness agent, add various polyol resins, resol and curing agent for epoxy resin.They all are effective to the water tolerance of improving tackiness agent, the cost that reduces tackiness agent.
Therefore, according to above-mentioned the present invention,, thereby be suitable for applying high-tension printing distributing board because anti-vestige electric leakage property is good, and because acid-proof, thereby can obtain to have the Copper Foil of the tackiness agent of variety of issue when avoiding Copper Foil etching formation conductor circuit.
