Detailed description of the invention
Precoating aluminum plate of the present invention, be for severing, being shaped is processed as the shape of expectation and carries with the outer sheet material of part etc. and the sheet material of structural elements as household electrical appliance goods and automobile.Below, just describe for the mode that realizes Precoating aluminum plate of the present invention.
(Precoating aluminum plate)
Precoating aluminum plate of the present invention is coated with the hard coat film being made up of resin on the surface of the aluminium sheet being made up of aluminum or aluminum alloy.In Precoating aluminum plate of the present invention, hard coat film can form on two sides, also can in one side, form.
Below, describe for the each key element that forms Precoating aluminum plate of the present invention.
(aluminium sheet)
Aluminium sheet is the base material of Precoating aluminum plate, can apply 1000 industrial pure that are, 3000 Al-Mn that are and be associated the Al-Mg that gold, 5000 is and be associated gold, selects according to purposes.While particularly implementing drawing processing and attenuate, recommend A1050, A1100, A3003, the A3004 of JISH4000 defined.In addition, in the time requiring to use in high-intensity purposes, recommend A5052, A5182.Be not particularly limited for modified, thickness of slab, can select according to purposes and object.
The preferred effects on surface of aluminium sheet is implemented substrate processing, and hard coat film between form substrate processing layer.By substrate processing layer, the adhesion of aluminium sheet and hard coat film improves, and the corrosion resistance of aluminium sheet improves in addition.As substrate processing layer, can be suitable for more than one the film of the always known Cr of containing, Zr, Ti.For example, can suitable use chromium phosphate hydrochlorate film, chromic acid chromium hydrochlorate film, basic zirconium phosphate film, zirconia film, titanium phosphate film, application type chromate film, application type zirconium film etc.In addition, also can make as required these films contain organic principle.From considering in recent years the viewpoint of environment, preferably use not chromyl chromium phosphate hydrochlorate film, basic zirconium phosphate film, zirconia film, titanium phosphate film and application type zirconium film etc.The thickness of substrate processing layer, as benchmark, preferably with Cr, Zr, Ti, the adhesion amount to aluminium sheet (Cr, Zr, Ti scaled value) is counted 10～50mg/m
2left and right.Adhesion amount is lower than 10mg/m
2time, can not be equably by whole of covering aluminum plate, Results fully.On the other hand, if adhesion amount exceedes 50mg/m
2, easily there is crackle in substrate processing layer self.Cr, Zr, Ti scaled value, for example, can measure by the easy of fluorescent X-ray method comparison and quantitatively.Therefore, can not hinder productivity ratio and carry out the qualitative control of aluminium sheet.
(hard coat film)
In Precoating aluminum plate, hard coat film is in order to utilize its hardness to give surface with scratch resistance, and arranges to give formability by flexible and lubricity.More than hard coat film is formed as thickness 0.2 μ m, below 10 μ m, by containing carbon (C), nitrogen (N) with ormal weight respectively, the resin of silicon (Si) and oxygen (O) forms.
In Precoating aluminum plate of the present invention, in order to obtain sufficient scratch resistance, hard coat film, follows the regulation of JIS5600-5-4 and the pencil hardness measured, is preferably hardness more than 4H with damaging judge.Such hardness of hard coat film, can form the composition acquisition of the resin of this hard coat film as described later like this by control.
(thickness: the above 10 μ m of 0.2 μ m are following)
The thickness of hard coat film is more than 0.2 μ m, below 10 μ m.Thickness during lower than 0.2 μ m, cannot fully be obtained the effect of scratch resistance in Precoating aluminum plate.On the other hand, even if thickness exceedes 10 μ m, be also difficult to the further raising of Results, and because the hardness of hard coat film causes easy cracking.In addition, by making thickness in described scope, can be on the aluminium sheet of web-like, use roll coater to form continuously hard coat film, therefore productivity ratio excellence, cost face is also preferred.If thickness exceedes 10 μ m, the pick-up roller of roll coater is insufficient to the enhancing of coating, and it is large that the deviation of thickness significantly becomes.On the contrary, thickness during lower than 0.2 μ m, needs to improve the pressure between upper material roller and applicator roll, and roller easily wears away.
Hard coat film contains C by the scope more than 30 atom %, below 50 atom %, respectively more than 10 atom %, contain N, Si, O lower than the scope of 30 atom %, and the resin that contains Si with 0.8 times of above 1.2 times of following containing ratio (atom %) of O forms.In addition hard coat film is preferably at wave number 2100～2300cm
-1scope in there is the absorption peak of infrared absorption spectroscopy.Such hard coat film, is formed by silicones, modified silicone resin or silicate resin, as described later, can toast processing by the cold coating mixing, modulated resin material being coated on aluminium sheet and obtain.
(more than C:30 atom %, below 50 atom %)
C(carbon) be the main component that forms the resin of hard coat film, if contain in a large number, resin is softening, on the other hand, percentage elongation improves.In addition C is the composition of resin being given to lubricity.C containing ratio is during lower than 30 atom %, and the excessive hardening of hard coat film can not be followed the distortion of aluminium sheet when shaping, and that easily peels off or crack etc. is bad.On the other hand, if C containing ratio exceedes 50 atom %, the hardness deficiency of hard coat film, Precoating aluminum plate can not get scratch resistance.
(more than N:10 atom %, lower than 30 atom %)
N(nitrogen) be to give flexible and composition lubricity for the resin that forms hard coat film.N containing ratio is during lower than 10 atom %, and the flexible deficiency of hard coat film, film crackle occurs when shaping and peel off, in addition, lubricity deficiency, when shaping and the sliding of metal die poor, can not get formability.On the other hand, N containing ratio is 30 atom % when above, the flexible surplus of hard coat film and hardness deficiency can not get scratch resistance.
(Si, O: more than being respectively 10 atom %, lower than 30 atom %)
Silicon (Si) and oxygen (O) are to give the composition of hardness for the resin that forms hard coat film.The containing ratio of Si, O is during lower than 10 atom %, and the hardness deficiency of hard coat film, can not get scratch resistance.On the other hand, the containing ratio of Si, O is at 30 atom % when above, and it is superfluous that the hardness of hard coat film becomes, and formability reduces.
(Si/O ratio: 0.8～1.2)
Form the resin of hard coat film, more than Si containing ratio (atom %) is 0.8 times with respect to O containing ratio (atom %), below 1.2 times.If Si must exceed 1.2 times for O is many, hard coat film becomes really up to the mark, and formability reduces.On the other hand, Si is with respect to O during lower than 0.8 times, even if meet described containing ratio (more than 10 atom %), the hardness of hard coat film also significantly reduces, and not only can not get scratch resistance, and in the time being shaped, also can occur that hard coat film breaks etc. bad.
Form the resin of the hard coat film of Precoating aluminum plate of the present invention, except C, N, Si, O, also can contain H(hydrogen).The containing ratio of H is not particularly limited, but preferably lower than 10 atom %, that is, preferably the total of the containing ratio of C, N, Si, O exceedes 90 atom %.
Be formed at C, the N in the surperficial hard coat film of Precoating aluminum plate, the containing ratio of Si, O, for example can be with Glow Discharge Spectrometry (GD-OES) method, and X-ray photoelectron spectroscopic analysis (XPS, or ESCA) method is measured and is obtained.If the surface of measuring the hard coat film from being formed with Precoating aluminum plate to the degree of depth of the thickness of hard coat film, can detect the composition of the hard coat film of C etc., and also have the Al as the composition of aluminium sheet, or also have the interpolation element of aluminium alloy.The element being detected as the composition of hard coat film is C, N, Si, O, therefore measures and manage its atomic ratio (atom %).
(the absorption peak of infrared absorption spectroscopy: wave number 2100～2300cm
-1)
There is C, C triple bond and C, the resin of N triple bond, for example acrylonitrile-butadiene rubber is because toughness is high, so the hard coat film that contains such resin had both had sufficient hardness, give again Precoating aluminum plate with extra high formability, be suitable for implementing the member of the shaping that the such degree of finish of drawing and forming is large.These keys are in infrared absorption spectroscopy, in wave number 2100～2300cm
-1scope there is absorption peak, therefore Precoating aluminum plate of the present invention, preferably hard coat film has absorption peak in this scope.Such hard coat film can obtain as follows: manufacture method is illustrated as described later, the coating that has carried out modulation for the mode of the resin of the composition to become described regulation, than higher temperatures or long-time under toast processing and obtains.That is, infer the sclerosis being brought by heating and carry out fully, in resin, produce C thus, C triple bond and C, N triple bond.Particularly contain alkynyl, itrile group by being suitable for end, silicones and the coating containing alkali silicate resin etc., the cross-linking reaction of bringing through heating, can obtain the unit's of formation structure and have the resin of triple bond, and the hard coat film of toughness high heat stability is therefore preferred.
Be used to form the cold coating of hard coat film, from the productivity ratio of Precoating aluminum plate and the viewpoint of cost, preferably can carry out continuous application with roll coater, carry out the baking of the short time about 20～60 seconds and the material that hardens with oven.As the material of such cold coating, can enumerate methyl silicon resin, phenyl polysiloxane, aminoalkyl silicones, epoxide modified silicones, urethane-modified silicones, containing acrylate silicones, containing alkali silicate resin etc.
Hard coat film is to contain described C, N, the resin of Si, O, but in addition, the composition that also can contain other according to necessity.For example, in order further to improve press formability, the lubricant that also can make it to contain palm oil, the western palm wax of horse, Tissuemat E, microwax etc. more than one.In addition,, in order to ensure the general performance of the coating as coating and precoated metal sheet, hard coat film also can contain the face material, face material dispersant, fluidity regulator, the levelling agent that generally use, antifoam agent, anticorrisive agent, stabilization agent etc.
(manufacture method of Precoating aluminum plate)
Then, describe for the manufacture method of Precoating aluminum plate.The manufacture method of Precoating aluminum plate of the present invention, carries out: the painting process of the coating that coating contains C, N, Si, O on the one or both sides of aluminium sheet; More than 210 DEG C, below 280 DEG C, toast and process and the roasting procedure of formation hard coat film for the coating of coating.
(painting process)
The coating of coating, with any one methods such as brushing machine, roll coater, curtain stream coating machine, curtain roll coater, electrostatic atomizer, knife type coater, die coater carry out can, but coating weight roll coater even and easy and simple to handle particularly preferably.In addition, consider the conveyance speed of aluminium sheet, direction of rotation and the rotating speed etc. of roll coater, suitable adjustment coating weight, so that form the hard coat film of the thickness of the expectation of the scope of 0.2～10 μ m on the surface of aluminium sheet.
Before carrying out painting process, also can carry out the degreasing process of the surperficial degreasing to aluminium sheet.For example, wash after the jet surface aqueous alkali of aluminium sheet.
In addition,, before carrying out painting process, also can carry out forming on the surface of aluminium sheet the substrate processing operation of substrate processing layer.For example, the aluminium sheet after described degreasing process being implemented to chromium phosphate hydrochlorate processes and formation chromium phosphate hydrochlorate film.
(roasting procedure)
Toast processing for the aluminium sheet that has been coated with coating, described coating is hardened and become hard coat film.Baking temperature be preferably 210 DEG C above, below 280 DEG C, if in such temperature range, process and just can obtain hard coat film with the baking of short time of 20～60 seconds.What further, baking temperature was aluminium sheet is up to Da Wendu.The baking processing time is during lower than 20 seconds, toast likely insufficiently, on the other hand, under this baking temperature, exceedes 60 seconds even if baking is processed, also can further not harden, and the productivity ratio reduction of unit interval.In addition, baking temperature is during lower than 210 DEG C, and under the baking in 20 seconds is processed, the sclerosis of coating is insufficient, and the hardness of hard coat film is insufficient.More preferably baking temperature is more than 230 DEG C, and the baking processing time is 20～50 seconds.According to the baking processing of the high temperature of such comparison, easily form and there is C, C triple bond and C, the resin of N triple bond.If but baking temperature exceedes 280 DEG C, coating starts to decompose, and therefore the hardness of hard coat film reduces on the contrary.Or baking temperature is during lower than 210 DEG C, carries out baking for a long time and process and also can obtain hard coat film.Specifically, if the baking processing time is 1 hour, can make baking temperature is 130 DEG C, and making in addition baking temperature is 150 DEG C, can form and have C, C triple bond and C, the resin of N triple bond.Baking is processed and can be used hot-blast stove, induction heater, near-infrared line oven, far infrared stove, energy line hardening furnace etc. to carry out.
