Description
Technical field
The present invention is relevant a kind of invention that household electrical appliances, building material made etc. have the metallic sheet material of excellent corrosion resistance, coating, anti-finger printing and processibility that can be used for.
Background technology
Generally speaking, steel plate, Aludip, contain metallic sheet materials such as zinc steel plating plate or aluminium sheet and be widely used more in fields such as automobile, building materials and electrical home appliances.But, zinc or aluminium are many in atmosphere corrosion can to take place and generation corrosion product (i.e. " white rust "), except that can cause the metallic substance outward appearance not good, also can produce detrimentally affect to coating, when making goods through various steps again according to various different demands in addition, it is attached to it that often the process of handling because of operator makes greasy dirt such as fingerprint, and can exist cause the significantly reduced doubt of commodity value or, add the needs of removing after the wet goods moulding that needs man-hour to use in carrying out punching press etc. as lubricant.
So when going up the erosion resistance, coating, fingerprint of note metal material surface and processibility for improvement, the metallic sheet material that following method makes is used for punch process, described metallic sheet material generally carries out after chromic acid handles as the treatment solution of main body more than using on the metal material surface with chromic acid, dichromic acid or its esters, is had and contains not the metallic sheet material of coating agent gained of lubricated composition that can form the wax etc. of processibility because of wet goods in the polyolefin-based resins of carboxyl or the coated with resin coated with containing colloided silica and wax etc. thereon again.
But, surging gradually because of environmental consciousness in recent years, and the people is known from experience exert an adverse impact because of handling 6 valency chromium that the employed chromic acid treatment solution of metal material surface contained, so generally avoid using the chromic acid processing more.In addition, the waste water that contains 6 valency chromium need be handled especially according to the water prevention and cure of pollution law regulation, and this also has the doubt that causes whole cost to go up for all.Again, carry out the metallic substance that chromic acid is handled, will form the industrial waste that contains chromium and have the shortcoming of can't recirculation using, and can form society and go up great problem.
Surface preparation beyond chromic acid is handled, known general use contains the Weibull of multi-phenol carboxylic acid as surface treatment agent.When using the tannin aqueous acid that metallic substance is handled,, can form obstruct for the immersion of corrosive deposit, and the erosion resistance of note metallic substance promotes upwards before making because of the formed protection tunicle of the reaction of Weibull and metallic substance.
But, in recent years,, general many to require tunicle itself should have high corrosion resistance along with the demand of high-qualityization of goods.But Weibull is independent or also neither fully with its erosion resistance of tunicle of inorganic components gained, still belongs to the very thing of difficulty so will make it reach practicability at present.
Again, improve the treatment process of the erosion resistance of metallic substance, for example special opening promptly has the method that the aqueous solution that uses water-dispersible silica and Synolac and trialkoxy silane compound to constitute is coated the metallic surface that discloses among the clear 53-121034.
Again, the aqueous solution that uses the hydroxy pyrone compound to constitute, to give the surface treatment method that the metallic substance erosion resistance is a purpose, and the method that the water-soluble or aqueous dispersion polymers that uses the hydroxy styrenes compound is given erosion resistance to metallic substance then is disclosed in special public clear 57-44751 communique, opens in the flat 1-177380 communique with the spy.
But no matter any method all can't obtain the tunicle with excellent corrosion resistance of the chromic salt tunicle gained of alternative metal material surface, so in fact all fail to solve for preceding note problem.Therefore, still failing at present to obtain the Chrome-free that a kind of metallic substance with excellent corrosion resistance uses is surface treatment agent and surface treatment method.
Summary of the invention

Below will do detailed explanation to the present invention.
The coating composition that is used for metallic sheet material of the present invention, contain, have silane coupling agent composition (A) that specific reactivity functional group's silane coupled compound more than a kind forms with, polymerization composition (B) that constitutes by the resol based polymer that contains special amino more than a kind and, wax composition (C).
Contained silane coupled compound in the silane coupling agent composition used in the present invention (A), if in 1 molecule, contain when being selected from the amino that contains active hydrogen, epoxy group(ing), vinyl, sulfydryl and methacryloxy compound as at least one of reactive functional group, then special qualification do not arranged in textural, particularly, for example can use and have down 1.～5. compound of component content of note.
1. has amino person

3. the person that has the vinyl
Vinyltriethoxysilane
4. the person that has the sulfydryl
3-sulfydryl propyl trimethoxy silicane
5. the person that has the methacryloxy
3-methacryloxypropyl trimethoxy silane, 3-methacryloxypropyl methyl dimethoxysilane
Silane coupling agent composition used in the present invention (A) preferably contains
The silane coupling agent (a) that constitutes by the silane coupled compound of the amino that contains 1 above active hydrogen more than a kind with
The silane coupling agent (b) that constitutes by the silane coupled compound that contains 1 above epoxy group(ing) more than a kind.
Again, silane coupling agent composition used in the present invention (A) is if when the silane coupling agent (a) that is made of the silane coupled compound of the amino that contains active hydrogen is constituted with the silane coupling agent (b) that contains epoxy group(ing), the contained amino that contains active hydrogen in the silane coupling agent, its equivalence ratio to epoxy group(ing) was good with 3: 1～1: 3.If surpass at 3: 1 o'clock, the film-forming properties of coating composition will worsen and erosion resistance, coating or the processibility of prepared metallic sheet material are worsened this amino that contains active hydrogen to the equivalence ratio of epoxy group(ing).Again, if be lower than at 1: 3 o'clock, coated metallic sheet material, its erosion resistance, coating, anti-finger printing or processibility will be state of saturation.
Again, component of polymer used in the present invention (B) is the oligopolymer or the polymkeric substance of polymerized unit shown in the note formula (1) before containing, and the mean polymerisation degree of formula (1) polymerized unit (following represent with n) is 2 to 50.
In the formula (1), with phenyl ring bonded X, be hydroxyl, the alkyl of C1 to C5 is methyl, ethyl, propyl group etc. for example, and the hydroxyalkyl of C1 to C5 is methylol, hydroxyethyl, hydroxypropyl etc. for example, and the aryl of C6 to C12 is phenyl, naphthyl etc. for example, benzyl, benzylidene, the unsaturated alkyl that can form naphthalene nucleus with preceding note phenyl ring condensation for example-CH=CH-CH=CH-or=CH-CH=CH-CH=, or be the base shown in the preceding note formula (2).
In the formula (2), R1 and R2 can separately be hydrogen atom, hydroxyl, and the alkyl of C1 to C10 is methyl, ethyl, propyl group etc. for example, and the hydroxyalkyl of C1 to C10 is methylol, hydroxyethyl, hydroxypropyl etc. for example.
In formula (1) and the formula (2), can with phenyl ring bonded Y1 and Y2, be hydrogen atom independently separately mutually, or the Z base shown in time note formula (3), (4).Again, R3, R4, R5, R6 and the R7 in formula (3) and (4) is separate to be alkyl for example methyl, ethyl, the propyl group etc. of C1 to C10, and the hydroxyalkyl of C1 to C5 is methylol, hydroxyethyl, hydroxypropyl etc. for example.
Can with Y2 in X, Y1 and the formula (2) in each phenyl ring bonded formula (1) in the preceding note polymer molecule, reach with other phenyl ring bonded X, Y1, Y2 can be identical or different each other mutually.Again, the mean value of the replacement number of the preceding note Z base of each phenyl ring is 0.2 to 1.0 in the preceding note polymer molecule.
The mean value of the replacement number of Z base, be in the polymer molecule all phenyl ring import the mean value of the number of Z base separately.For example in formula (1), n=10, and X is when containing phenyl ring basic in the formula (2), per 1 molecule phenyl ring number of this polymkeric substance is 20, if when importing 1 Z base separately on 10 phenyl ring in this polymkeric substance 1 molecule, it is ((1 * 10)+(0 * 10))/20=0.5 that the Z base of this polymer molecule replaces mean value.
The mean value that this Z base replaces number is lower than at 0.2 o'clock, can cause resulting polymers to the adaptation deterioration of metallic substance coating to be worsened.If surpass at 1.0 o'clock, then the wetting ability of resulting polymers will increase, and makes the erosion resistance of gained metallic sheet material insufficient again.
Shown in formula (3) and the formula (4) in the Z base, R3～R7 respectively the do for oneself alkyl of C1 to C10, the hydroxyalkyl of C1 to C10.If when this carbon number 11 is above, will the film-forming properties of formed coating composition be reduced, and make erosion resistance, coating, anti-finger printing or processibility not good.
Wax composition used in the present invention (C) does not have special qualification, is that 40～120 ℃ of persons are for good with fusing point.Use the metallic sheet material that surpasses the outer wax composition gained of this melting range, its processibility is insufficient.
Among the present invention, the lining weight on metallic sheet material surface is with 0.01～3.0g/m
2For good.This lining weighs less than 0.01g/m
2The time, will reduce erosion resistance, anti-finger printing and the processibility etc. of gained metallic sheet material.Surpass 3.0g/m again,
2The time, can cause coating, particularly adaptation deterioration.
In the employed coating composition, preceding note silane coupling agent composition (A) was good to the weight ratio (A)/(B) of preceding note water-soluble polymers composition (B) with 1: 10 to 10: 1, was more preferred from 1: 1 to 5: 1 in the manufacture method of the present invention.This weight ratio is lower than at 1: 10 o'clock, and promptly the ratio of silane coupling agent composition (A) is crossed when low, and the clinging power of itself and matrix surface will reduce, and causes the not good situation of erosion resistance, coating.Again, its ratio is if surpass at 10: 1 o'clock, when promptly the ratio of silane coupling agent composition (A) is too high, because of the film-forming properties of coating composition reduces, so the erosion resistance of gained metallic sheet material, coating are insufficient.
In the manufacture method of the present invention in the employed coating composition, before the content of note wax composition (C) special qualification is not arranged, being preferably weight ratio (C)/((A)+(B)) of the total weight of silane coupling agent composition (A) and component of polymer (B) is good with 1/100～2/1 scope.Wax composition (C) is lower than at 1/100 o'clock, and its anti-finger printing, processibility are not good, surpasses at 2/1 o'clock, because of the film-forming properties of coating composition reduces, so the erosion resistance of gained metallic sheet material, coating are insufficient.
Below will describe manufacture method of the present invention.In the manufacture method of the present invention, be that the waterborne compositions that contains coating composition that the pH value is adjusted to 2.0～6.5 scopes is coated on the metallic sheet material surface, making it be dried to dry back lining weight subsequently is 0.01～3.0g/m
2, be preferably 0.05～1.5g/m
2Degree.Type of heating is good with the metallic sheet material heat drying that will be coated with waterborne compositions.
Again, in the manufacture method of the present invention, waterborne compositions is that preceding note coating composition is with the water-based medium, water is diluted, or under undiluted, modulate, in this situation, the pH value for example can use phosphoric acid, sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, fluoro complex (wrong Off ッization thing) the pH value to be adjusted to 2.0～6.5 scope with organic acid.
The employed waterborne compositions pH of manufacture method of the present invention value adjustment mode is good to use phosphoric acid, superphosphate, fluorochemical, fluoro complex.Better pH value is 3.0～5.0 scope.The pH value is lower than at 2.0 o'clock, because of the excessive reactivity of coating composition and matrix surface in the gained waterborne compositions, so the bad situation of lining takes place easily.Again, the pH value surpasses at 6.5 o'clock, because of water-soluble polymers composition (B) itself is very easily separated out by precipitation in the waterborne compositions, and can make the lost of life of waterborne compositions.
Again, use the method on this waterborne compositions coated metal material surface that special qualification is not arranged, for example can use pickling process, spray method, and mode such as rolling method be coated with.Again, the metallic substance through coating carries out drying for good with type of heating.It is good that Heating temperature then arrives 50～180 ℃ scope with the temperature of metallic sheet material.
Again, in the manufacture method of the present invention, when waterborne compositions contacts with metallic substance, will form complex compound with water-soluble polymers composition (B), produce sedimentary situation and take place and have by the metal ion of stripping in the metallic substance.Can add the metal shadowing agent this moment in surface treatment composition.Metal shadowing agent for example EDTA, Cy-DTA, trolamine, glyconic acid, seven glyconic acids, oxalic acid, tartrate, oxysuccinic acid and organic phospho acid etc. is good.
In the employed waterborne compositions of manufacture method of the present invention, when promoting coating, desire can add tensio-active agent again.Anion surfactant, polyethylene glycol type nonionogenic tenside, polyol-based non-ionic surfactant, amine cation tensio-active agents etc. such as for example commercially available carboxylic acid type of tensio-active agent, sulfuric acid type, sulfonate type, phosphate ester salt type.
Employed metallic substance among the present invention for example can be by steel plate, steel plate galvanized, to aluminize be selected persons such as steel plate, aluminium alloy plate, stainless steel plate, copper coin.
Use the metallic sheet material of the employed waterborne compositions lining of manufacture method of the present invention can have excellent corrosion resistance, anti-finger printing, processibility etc., it is fully clear that its mechanism of action is still failed, but present inventors think that its mechanism of action should be down note mechanism.Produce etching because of the sour composition in the waterborne compositions makes the metallic surface, and the pH value at interface is risen, via the reaction of the metal ion and the water-soluble polymers composition of stripping, and in the tunicle of interface formation insoluble.The barriering effect of having been given play to through this insoluble tunicle, and improve its erosion resistance.But, if only as this moment, the adaptation of metallic substance and tunicle will be lower, so and if during with the silane coupling agent composition, can form oxyethane (ォ キ サ Application) key with metal material surface because of hydrolysis makes the functional group's (OR yl) in the silane coupling agent, in addition, another reactive functional group partly then produces reaction with the water-soluble polymers composition in the silane coupling agent, and then promotes the adaptation of metallic substance and water-soluble polymers composition and application.Again, the wax composition that contains simultaneously should be the factor that causes anti-finger printing and processibility to promote.
