Another aspect of the present invention is a kind of method of making resin coating metal plate, and it may further comprise the steps: the preparation emulsion compositions; This emulsion compositions of coating on metallic plate; Heating and the drying coated metallic plate of emulsion compositions.
The specific embodiment
Resin coating metal plate of the present invention comprises the resin molding that forms in the supreme side of metallic plate from specific emulsion compositions.Metallic plate is not particularly limited.For example, can should be mentioned that steel plate, aluminium sheet, aluminum series alloy plate or titanium plate zinc-plated or zinc system.And, metallic plate is handled or other surface treatment through known antirust surface treatment such as phosphatization, and to form resin molding thereon also be acceptable.From the viewpoint of environmental problem, preferably this sheet material is handled without chromaking.
The emulsion compositions that is used for forming in the present invention resin molding contains the ethene/copolymers of unsaturated carboxylic acids (comprising neutral condition) as key component, boiling point is 100 ℃ or lower amine, its amount is contained carboxyl in 0.2-0.8 mole (20-80 mole %)/molar ethylene/copolymers of unsaturated carboxylic acids, one divalent metal compound, its amount is contained carboxyl in 0.02-0.4 mole (2-40 mole %)/molar ethylene/copolymers of unsaturated carboxylic acids, also has crosslinking agent, its amount is 0.5-20 quality %/100 quality % emulsion compositions solid contents, this crosslinking agent have 2 or a plurality of can with the functional group of carboxyl reaction, and said composition does not contain amine and ammonia that boiling point is higher than 100 ℃ substantially.
Described ethene/copolymers of unsaturated carboxylic acids is the copolymer of ethene and ethylenic unsaturated carboxylic acid.As unsaturated carboxylic acid, can should be mentioned that (methyl) acrylic acid, crotonic acid, iso-crotonic acid, maleic acid, fumaric acid, itaconic acid etc.By known method polymerizations such as high temperature high-pressure polymerization process one or more and ethene wherein, can obtain described copolymer.This copolymer most preferably is a random copolymer.Yet it also can be block copolymer or the copolymer of partly locating grafting at unsaturated carboxylic acid.By the way, unsaturated carboxylic acid (methyl) acrylic acid preferably.And, also can adopt olefinic type monomers such as propylene or 1-butylene to replace a part of ethene.And then, the also monomer of other known vinyl type of copolymerization (amount for about 10 quality % or lower) partly, only otherwise damaging purpose of the present invention gets final product.
For the copolymerization ratio of unsaturated carboxylic acid and ethene, when the monomer total amount was considered as 100 quality %, the amount of unsaturated carboxylic acid was preferably 10-40 quality %.When the amount of unsaturated carboxylic acid is lower than 10 quality %, too little as the amount of the carboxyl of the crosslinking points of the basic point of intermolecular association or crosslinking agent via ion cluster.Therefore, disadvantageously, do not bring into play the film-strength effect, like this, the decay resistance behind fissility of anti-adhesive tape the and the defatting step can be insufficient.In addition, the emulsion stability of emulsion compositions is poor.The more preferably lower limit of unsaturated carboxylic acid amount is 15 quality %.On the other hand, when the amount of unsaturated carboxylic acid surpassed 40 quality %, the decay resistance and the water resistance of resin molding were poor.Therefore, disadvantageously, the decay resistance behind the defatting step can reduce equally.The preferred upper limit is 25 quality %.
Described ethene/copolymers of unsaturated carboxylic acids has carboxyl.Therefore, can it be neutralized, make emulsion (making aqueous dispersion) thus with organic base or metal ion.In the present invention, be that 100 ℃ or lower amine are as organic base with boiling point.Boiling point is higher than 100 ℃ amine and is retained in easily on the steel plate when resin-coated film is dry, causes resin-coated film water absorbing properties to improve.This causes the decline of decay resistance.For this reason, boiling point not being higher than 100 ℃ amine is included in the emulsion compositions that is used to form film of the present invention.And, do not comprise ammonia, because do not observe the additive effect of ammonia as yet yet.As boiling point, employing be boiling point under the atmospheric pressure.
Boiling point is that the instantiation of 100 ℃ or lower amine comprises: tertiary amine such as triethylamine, N, N-dimethyl butylamine, N, N-DMAA, N-methyl pyrrolidone, tetramethyl diaminourea methane and trimethylamine; Secondary amine such as N-Methylethyl amine, diisopropylamine and diethylamine; With primary amine such as propylamine, tert-butylamine, sec-butylamine, isobutyl amine, 1,2-dibutyl propyl group amine and 3-amylamine.These can use separately or with two or the form of more kinds of mixture use.Wherein, preferred tertiary amine, most preferably triethylamine.
With boiling point is that the amount of 100 ℃ or lower amine is set at the carboxyl in 0.2-0.8 mole (20-80 mole %)/molar ethylene/copolymers of unsaturated carboxylic acids.This is because the amount in this scope can cause excellent corrosion resisting performance and the fissility of anti-the adhesive tape.When boiling point is the amount of 100 ℃ or lower amine during less than 0.2mol, the particle diameter of resin particle is bigger in the emulsion., can contemplate for this reason, can not bring into play aforesaid effect.Yet when boiling point is the consumption of 100 ℃ or lower amine during greater than 0.8mol, viscosity can take place and raise and gel in emulsion compositions unfriendly.The amount of amine more preferably on be limited to 0.6mol, 0.5mol more preferably.The amount of amine more preferably be limited to 0.3mol down.
In the present invention, also monovalent metallic ion is used for neutralization.This is effective for improving solvent resistance and film hardness.Therefore, in emulsion compositions, add a divalent metal compound.A described divalent metal compound preferably contains one or two or more kinds of metal that is selected from sodium, potassium and lithium.Hydroxide, oxycarbide or the oxide of more preferred metals.Wherein, preferred NaOH, KOOH, LiOH etc., NaOH most preferably is because it has optimum performance.And, for two or more the high price metallic compound, do not observe the effect that interpolation produces.Therefore, the emulsion compositions that is used for film forming does not in the present invention contain two or high-valency metal compound more as the reactive component of ethene/copolymers of unsaturated carboxylic acids.
The amount of one divalent metal compound is set in carboxyl in 0.02-0.4 mole (2-40 mole %)/molar ethylene/copolymers of unsaturated carboxylic acids.When the amount of described metallic compound was lower than 0.02mol, it is insufficient that emulsion stability becomes.Yet when this amount surpassed 0.4mol, the moisture pick-up properties of the resin molding that obtains (particularly to alkaline solution) improved, and caused the decay resistance variation behind the defatting step unfriendly.The more preferably lower limit of described metallic compound amount is 0.03mol.Further preferred lower limit is 0.1mol.The more preferably upper limit of metallic compound amount is 0.5mol, and further preferred upper limit is 0.2mol.
Using boiling point with preferred amount in above-mentioned scope separately is 100 ℃ or a lower amine and a divalent metal compound.The two all is used for the carboxyl and the emulsified copolymer of neutralization of ethylene/copolymers of unsaturated carboxylic acids.Therefore, when its total amount (dosis neutralisata) was too big, disadvantageously, the viscosity of emulsion compositions improved rapidly and solidifies, and in addition, excessive alkaline constituents causes the corrosion resistance variation.And, need lot of energy to make excessive alkaline constituents volatilization.Yet, when dosis neutralisata too hour, disadvantageously, but also variation unfriendly of emulsibility.Therefore, boiling point is that the total amount of 100 ℃ or a lower amine and a divalent metal compound preferably sets the carboxyl in 0.3-1.0 moles/mole ethene/copolymers of unsaturated carboxylic acids.
Being used in combination boiling point and being 100 ℃ or lower amine and a divalent metal compound carries out emulsification and has formed and be used for emulsion compositions of the present invention.As a result, the resin particle in the composition stably is present in the water-bearing media with superfine little particle (oil droplet) form that is of a size of 5～50nm.Infer this filming performance that can realize the resin molding that obtains, densified to the adhesion of metallic plate and film, obtained improvement decay resistance and the fissility of anti-the adhesive tape.Described water-bearing media can contain hydrophilic solvent such as alcohol or ether beyond water.By the way, the resin particle particle diameter in the emulsion can be measured by the laser diffractometry that for example adopts light scattering photometer (OTSUKA ELECTRONICSCo., Ltd. makes).
Be in the single neutralization procedure (emulsifying step) that belongs to ethene/copolymers of unsaturated carboxylic acids that compound carries out of 100 ℃ or lower amine and monovalence with boiling point, wish that almost side by side adding boiling point in copolymer is 100 ℃ or a lower amine and a divalent metal compound, perhaps adding boiling point earlier is 100 ℃ or lower amine.This is because it is that 100 ℃ or lower amine can cause the insufficient of the decay resistance/fissility of anti-adhesive tape improvement effect that the back adds boiling point, although its reason and not clear.
Carboxyl is that the ethene/copolymers of unsaturated carboxylic acids of 100 ℃ or lower amine and divalent metal compound neutralization forms intermolecular association (being converted into ionomer) via ion cluster by boiling point, to form the resin molding of the decay resistance/fissility of anti-adhesive tape excellence.Yet,, wish that polymer chain utilizes the reaction between functional group to be cross-linked to each other via chemical bond for forming more strong film.Under these circumstances, emulsion compositions of the present invention contains crosslinking agent as solvent, and it has two or the functional group of the enough and carboxyl reaction of multipotency more.Its amount is set in the emulsion compositions solid content of 1-20 quality %/100 quality %.When this amount is lower than 1 quality %, become insufficient by the crosslinked effect of chemical bond.Therefore, so easy performance is to the improvement effect of decay resistance/fissility of anti-the adhesive tape.On the other hand, when when sneaking into crosslinking agent greater than the amount of 20 quality %, the crosslink density of resin molding excessively increases, and causes the raising of hardness.Therefore, resin molding become can not be along the time with compression moulding distortion, this causes the formation of crackle.As a result, but decay resistance and coating have been reduced unfriendly.Preferred dosage of crosslinking agent is the solids content of 5-10 quality %/100 quality % emulsion compositions.By the way, for the ratio of the amount of the amount of crosslinking agent and ethene/copolymers of unsaturated carboxylic acids, the amount of wishing crosslinking agent suitably changes according to the amount of carboxyl in the copolymer.Usually, the amount of crosslinking agent is preferably 0.5-50 mass parts (more preferably 5-20 mass parts)/100 mass parts copolymers.
Each molecule have 2 or more the crosslinking agent of the functional group of the enough and carboxyl reaction of multipotency be not particularly limited.Yet, its preferred embodiment can comprise: the crosslinking agent that contains glycidyl, comprise the many glycidyl ethers of many glycidyl ethers such as D-sorbite, the many glycidyl ethers of (gathering) glycerine, the many glycidyl ethers of pentaerythrite, the many glycidyl ethers of trimethylolpropane, neopentyl glycol diglycidyl ether and (gathering) ethylene glycol bisthioglycolate glycidyl ether and many glycidyl group amines; Two sense aziridine cpds are as 4,4 ' a pair of (aziridine carbonylamino) diphenyl methane, N, N '-hexa-methylene-1,6-two (1-aziridine Carboxylamide), N, N '-diphenyl methane-4,4 '-two (1-aziridine Carboxylamides) and the two aziridine Carboxylamides of toluene; With the crosslinking agent that contains '-aziridino, comprise three or more polyfunctional aziridine cpd, as three-1-'-aziridino phosphine oxide, three [1-(2-methyl) '-aziridino] phosphine oxide, trimethylolpropane tris (β-'-aziridino propionic ester), three-2,4,6-(1-'-aziridino)-1,3,5-triazine and tetramethyl propane four '-aziridino propionic esters, or derivatives thereof.They can use separately, or make up two or more uses.Wherein, the crosslinking agent that preferably contains '-aziridino.By the way, can be used in combination polyfunctional aziridines class and simple function aziridines (as aziridine).
The emulsion compositions that is used for the present invention can contain silica dioxide granule with the amount of 5-40 quality %, based on solid content meter.But this is for improving decay resistance coating, anti-crack performance etc. effectively, and is also effective to decay resistance and the fissility of anti-adhesive tape the after the improvement degreasing.When this amount is lower than 5 quality %, be not easy to generate these effects so.Yet when this amount surpassed 40 quality %, the ratio of silica dioxide granule excessively increased, and causes the reduction to filming performance.Therefore, in the resin molding crackle can take place, cause the reduction of decay resistance unfriendly in drying steps.And silica dioxide granule is as buffing compound, and the lubricity that this has improved film causes the decline of coefficient of friction.This causes in the forming process the wearing and tearing of mould, has shortened the life-span of mould.The silica dioxide granule amount more preferably be limited to 20 quality % down, be limited to 30 quality % on it.
In order to make the above-mentioned maximum effect of silica dioxide granule, the average grain diameter of silica dioxide granule is preferably 1-200nm.Along with the decline of silica dioxide granule particle diameter, the decay resistance of film is improved.Can infer and be due to the fact that.Resin molding is by densified, and adhesion improves, and this has further improved decay resistance.Based on this viewpoint, wish that silica dioxide granule has littler particle diameter.Yet, when they are superfine little particle, the aforementioned effect state that reaches capacity.For this reason, the lower limit of particle diameter is preferably 1nm.On the other hand, when the silica dioxide granule particle diameter surpassed 200nm, surface resin film was roughened.Therefore, can not form fine and close resin molding.And also as buffing compound, this has caused the deterioration of formability to silica dioxide granule unfriendly.Especially, when the decay resistance after the attention degreasing, the particle mean size of silica dioxide granule is preferably set to 4-20nm.
The so-called cataloid of silica dioxide granule like this.In the present invention, can for example preferably adopt (Nissan Chemical Industries, the cataloids that Ltd. produces) such as " XS ", " SS ", " 40 ", " N ", " UP " of " Snow Tex series ".
In emulsion compositions of the present invention, can contain the wax of 0.5-20 quality %, based on solid content meter.Described wax has the lubricity of the resin molding that obtains and the improvement effect of anti-crack performance.And, it is preferred for improving in the required drawability of compression moulding and stamping-out and stampability, resistant to mold wear energy and the moulding anti-sliding surface melanism performance and excellent formability is provided.
When the amount based on solid content meter wax was lower than 0.5 quality %, the lubricity of the resin molding of formation became insufficient.Therefore, can not improve anti-crackle and the gratifying formability of acquisition.On the other hand, when this amount surpassed 20 quality %, the resin molding of formation had sufficient lubricity, and still, when making it through the back coating of electro-deposition, powder coated or serigraphy, the adhesiveness of its film (but coating) is relatively poor.And decay resistance after the degreasing and the stripping performance of anti-the adhesive tape be variation also.May be due to the fact that.Wax can perhaps change in time by heating to come softening/liquefaction or frosting in the application step of back, and concentrate between resin molding and back coated film at the interface or metallic plate and resin molding at the interface.Therefore, with the adhesion of back coated film or with the adhesion variation of metallic plate.Preferred higher limit is 10 quality %, even preferred higher limit is 5.0 quality %.
Described wax is not particularly limited, and available wax is native paraffin and synthetic wax and composition thereof etc.The example of available native paraffin comprises Brazil wax, rice wax, candelila wax and brown coal type wax, and derivative, mineral oil origin wax, microwax, paraffin etc., and by adding the derivative that carboxyl obtains.
As synthetic wax, can should be mentioned that the oxidized petroleum waves of the copolymer waxes of polyethylene, PEO, polypropylene, ethylene/propene copolymer type wax and ethene and other monomer.As this individual system,, can adopt the polytype that also comprises the terpolymer type according to the variation of copolyreaction component.And, can mention maleic acid adduct wax, fatty acid ester type etc.And fluorine resin type wax also is available as polytetrafluoroethylene (PTFE), polyvinyl fluoride, polyvinylidene fluoride and tetrafluoroethene.
As wax, preferably from above example, select softening point and be those of 80-140 ℃.When softening point was lower than 80 ℃, when compression moulding or stamping-out, Wax particles softened along with the rising of mold temperature/liquefaction.Therefore, the sliding surface place between resin-coated steel plate and mould, the liquid that liquefied wax can take place exhausts phenomenon, causes the decline of plastic performance.This causes scratch unfriendly and stings mould.And, can adhesion melanism material on slipper, badly damaged product appearance.And still decay resistance and the stripping performance of anti-adhesive tape viewpoint behind the defatting step shows that low excessively softening point is not preferred.On the other hand, when softening point surpassed 140 ℃, the lubricity that wax produces became insufficient.Therefore, stampability, anti-mould friction property, drawability etc. can not be improved.Decay resistance after the degreasing also shows slight downward trend.
Described wax most preferably is spherical Tissuemat E.In this case, in order to make the maximum effect of spherical polyethylene wax, the particle diameter of Wax particles is preferably 0.1-3 μ m.When the particle diameter of Wax particles during, be difficult to significantly improve lubricity, stampability, anti-mould friction property and drawability energy less than 0.1 μ m.On the other hand, when the particle diameter of Wax particles surpasses 3 μ m, be difficult to Wax particles is distributed in the emulsion compositions equably with the form of fine particle.This may reduce the adhesion of resin molding to metallic plate.The particle diameter of preferred spherical polyethylene wax is 0.3-1.0 μ m.
As aforesaid spherical polyethylene wax, can adopt and for example be purchased product as " DAIJETE-17 " (GOO Chemical Co., Ltd. production), " KUE-1 ", " KUE-5 " and " KUE-8 " (Sanyo Chemical Industries, Ltd. produce), (Mitsui Chemicals production) and " Elepon E-20 " (NICCA Chemical Co., Ltd. produces) such as " W-100 ", " W-200 " of " Chemipearl " series, " W-300 ", " W-400 ", " W-500 ", " W-640 ", " W-700 ".
