Embodiment
The Precoating aluminum plate of the present invention, be, for severing, formed machining, the shape expected and as the outer sheet material of household electrical appliance goods and automobile lift-launch part etc. and the sheet material of structural member. Hereinafter, just it is described for realizing the mode of the Precoating aluminum plate of the present invention.
(Precoating aluminum plate)
The 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 the Precoating aluminum plate of the present invention, hard coat film can be formed on two sides, it is also possible to is formed in one side.
Hereinafter, each key element of Precoating aluminum plate forming the present invention is described.
(aluminium sheet)
Aluminium sheet is the base material of Precoating aluminum plate, it is possible to the Al-Mg system alloy that the Al-Mn system alloy, 5000 that the industrial pure, 3000 that application 1000 is is is, selects according to purposes. When particularly implementing draw deep processing and subtract thin, recommend A1050, A1100, A3003, A3004 of JISH4000 defined. In addition, when using in the purposes requiring high strength, recommend A5052, A5182. For modified, plate is thick is not particularly limited, it is possible to select according to purposes and object.
Substrate processing is preferably implemented in surface by aluminium sheet, forms substrate processing layer between hard coat film. Adhesion by substrate processing layer, aluminium sheet and hard coat film improves, and the erosion resistance of aluminium sheet improves in addition. As substrate processing layer, it is possible to be suitable for always known more than one the film containing Cr, Zr, Ti. Such as, it is possible to be suitable for using phosphoric acid chromic salt film, chromic acid chromic salt film, zirconium phosphate film, zirconium white film, titanium phosphate film, application type chromic salt film, application type zirconium film etc. In addition, these films can also be made as required to contain organic composition. From the view point of consider environment in recent years, it is preferred to use not containing the phosphoric acid chromic salt film of sexavalent chrome, zirconium phosphate film, zirconium white film, titanium phosphate film and application type zirconium film etc. The thickness of substrate processing layer, as benchmark, it is preferable that with Cr, Zr, Ti, the adhesion amount (Cr, Zr, Ti conversion value) of aluminium sheet is counted 10��50mg/m2Left and right. Adhesion amount is lower than 10mg/m2Time, can not evenly by whole of covering aluminum plate, cannot abundant Results. On the other hand, if adhesion amount is more than 50mg/m2, then easily there is crackle in substrate processing layer self. Cr, Zr, Ti conversion value, such as, by simplicity that fluorescent X-ray method compares and can measure quantitatively. Accordingly, it may be possible to do not hinder productivity and carry out the qualitative control of aluminium sheet.
(hard coat film)
In Precoating aluminum plate, hard coat film is to utilize its hardness to give surface with scratch resistance, and arranges to give plasticity by flexible and oilness. Hard coat film be formed as thickness more than 0.2 ��m, less than 10 ��m, by containing carbon (C), nitrogen (N) with specified amount respectively, the resin of silicon (Si) and oxygen (O) is formed.
In the Precoating aluminum plate of the present invention, in order to obtain sufficient scratch resistance, hard coat film, the pencil hardness following the regulation of JIS5600-5-4 and measure, is preferably the hardness of more than 4H with damaging judge. Such hardness of hard coat film, it is possible to the composition of the resin being formed this hard coat film as aftermentioned by control is obtained.
(thickness: more than 0.2 ��m less than 10 ��m)
The thickness of hard coat film is more than 0.2 ��m, less than 10 ��m. When thickness is lower than 0.2 ��m, Precoating aluminum plate cannot fully obtain the effect of scratch resistance. On the other hand, even if thickness is more than 10 ��m, also it is difficult to the further raising of Results, and causes easy cracking due to the hardness of hard coat film. In addition, by making thickness be in described scope, it is possible on the aluminium sheet of volume shape, it may also be useful to roller coating machine forms hard coat film continuously, therefore productivity is excellent, cost face it is also preferred that. If thickness is more than 10 ��m, then roller coating machine to pick up roller insufficient to the enhancing of coating, the deviation of thickness significantly becomes big. On the contrary, when thickness is lower than 0.2 ��m, it is necessary to pressure between material roller and coating roller in raising, roller easily wears away.
Hard coat film is by containing C in the scope of 30 more than atom %, 50 below atom %, respectively 10 more than atom %, lower than the scope of 30 atom % in containing N, Si, O, and formed with resin containing Si of the containing ratio (atom %) of more than the 0.8 of O times less than 1.2 times. In addition hard coat film is preferably at wave number 2100��2300cm-1Scope in there is the absorption peak of infrared absorption spectrum. Such hard coat film, by silicone resin, modified silicone resin or silicate system resin formation, as aftermentioned, it is possible to obtain by mixing, the cold coating of having modulated resin material are coated on aluminium sheet in addition baking processing.
(C:30 more than atom %, 50 below atom %)
C (carbon) is the main component of the resin forming hard coat film, if containing in a large number, then resin softens, and on the other hand, unit elongation improves. In addition C is the composition that resin is given oilness. When C containing ratio is lower than 30 atom %, hard coat film is excessively hardening, can not follow the distortion of aluminium sheet during shaping, it is easy to occur to peel off or produce the bad of crackle etc. On the other hand, if C containing ratio is more than 50 atom %, then the hardness of hard coat film is not enough, and Precoating aluminum plate can not get scratch resistance.
(N:10 more than atom %, lower than 30 atom %)
N (nitrogen) gives composition that is flexible and oilness for the resin forming hard coat film. When N containing ratio is lower than 10 atom %, there is film crackle and stripping in hard coat film flexible not enough, in addition, oilness is not enough during shaping, during shaping and the sliding of metal die poor, can not get plasticity. On the other hand, when N containing ratio is 30 more than atom %, the flexibility of hard coat film is superfluous and hardness is not enough, can not get scratch resistance.
(Si, O: be respectively 10 more than atom %, lower than 30 atom %)
Silicon (Si) and oxygen (O) are the compositions resin forming hard coat film being given to hardness. When the containing ratio of Si, O is lower than 10 atom %, the hardness of hard coat film is not enough, can not get scratch resistance. On the other hand, the containing ratio of Si, O is when 30 more than atom %, and the hardness of hard coat film becomes superfluous, and plasticity reduces.
(Si/O compares: 0.8��1.2)
Forming the resin of hard coat film, Si containing ratio (atom %) is more than 0.8 times, less than 1.2 times relative to O containing ratio (atom %). If Si is many more than 1.2 times for O, then hard coat film becomes really up to the mark, and plasticity reduces. On the other hand, Si relative to O lower than 0.8 times time, even if meeting described containing ratio (10 more than atom %), the hardness of hard coat film also significantly reduces, and not only can not get scratch resistance, and also can occur when being shaped that hard coat film breaks etc. bad.
Form the resin of the hard coat film of the Precoating aluminum plate of the present invention, except C, N, Si, O, it is also possible to containing H (hydrogen). The containing ratio of H is not particularly limited, but preferably lower than 10 atom %, namely, it is preferable that the total of the containing ratio of C, N, Si, O is more than 90 atom %.
Be formed at Precoating aluminum plate surface hard coat film in the containing ratio of C, N, Si, O, such as can with glow discharge optical emission spectrometry analysis (GD-OES) method, carry out measuring and obtaining with X-ray photoelectron spectroscopic analysis (XPS, or ESCA) method. If measuring from the surface of the hard coat film being formed with Precoating aluminum plate to the degree of depth of the thickness of hard coat film, then can detect out the composition of the hard coat film of C etc., and also have the Al of the composition as aluminium sheet, or also have the addition element of aluminium alloy. The element being detected as the composition of hard coat film is C, N, Si, O, therefore measures and manages its atomic ratio (atom %).
(the absorption peak of infrared absorption spectrum: wave number 2100��2300cm-1)
There is C, C triple bond and C, the resin of N triple bond, such as paracril, because toughness height, so the hard coat film containing such resin, had both had sufficient hardness, give again Precoating aluminum plate with plasticity high especially, it is suitable for implementing the component of the big shaping of the such degree of finish of drawing and forming. These keys in infrared absorption spectrum, in wave number 2100��2300cm-1Scope there is absorption peak, the therefore Precoating aluminum plate of the present invention, it is preferable that hard coat film has absorption peak in this scope. Such hard coat film can obtain as follows: as illustrated by manufacture method described later, for the coating modulated in the way of becoming the resin of the composition of described regulation, than higher temperatures or long-time under carry out baking processing and obtain. That is, the hardening that presumption is brought by heating fully carries out, and thus produces C in resin, C triple bond and C, N triple bond. Particularly contain alkynes base, itrile group by applicable end, silicone resin and the coating containing alkali silicate resin etc., through heating the crosslinking reaction brought, it is possible to obtain forming the resin that unit there is triple bond, the hard coat film of toughness high heat stability, it is preferred to.
For the formation of the cold coating of hard coat film, from the view point of the productivity of Precoating aluminum plate and cost, it is preferable that continuous application can be carried out with roller coating machine, carry out the baking of the short period of time about 20��60 seconds with roaster and the material that hardens. As the material of such cold coating, methyl silicon resin, phenyl polysiloxane can be enumerated, aminoalkyl silicone resin, epoxide modified silicone resin, urethane-modified silicone resin, containing acrylate silicone resin, containing alkali silicate resin etc.
Hard coat film is the resin containing described C, N, Si, O, but in addition, it is also possible to other composition is contained according to necessity. Such as, in order to improve press formability further, it is also possible to make it the lubricant containing plam oil, the western palm wax of horse, polyethylene wax, Microcrystalline Wax etc. more than one. In addition, in order to guarantee the general performance of the coating as coating and prefinished metal plate, hard coat film can also contain general used material, material dispersion agent, fluidity regulator, flow agent, antifoam agent, sanitas, stabilization agent etc.
(manufacture method of Precoating aluminum plate)
Then, manufacture method for Precoating aluminum plate is described. The manufacture method of the Precoating aluminum plate of the present invention, carries out: on the one or both sides of aluminium sheet, coating contains the painting process of the coating of C, N, Si, O; More than 210 DEG C, less than the 280 DEG C coating for coating carry out baking processing and form the baking operation of hard coat film.
(painting process)
The coating of coating, with any one methods such as brushing machine, roller coating machine, curtain stream coating machine, curtain curtain roller coating machine, electrostatic atomizer, knife coater, die coater carry out can, but the roller coating machine that particularly preferably glue spread is even and easy and simple to handle. In addition, it is contemplated that to the sense of rotation of the conveyance speed of aluminium sheet, roller coating machine and rotating speed etc., be suitable for adjusting glue spread, so that the hard coat film of thickness of expectation of scope of surface formation 0.2��10 ��m at aluminium sheet.
Before carrying out painting process, it is also possible to carry out the degreasing process of the surperficial degreasing to aluminium sheet. Such as, to aluminium sheet surface injection alkali aqueous solution after wash.
In addition, before carrying out painting process, it is also possible to carry out the substrate processing operation of the surface formation substrate processing layer at aluminium sheet. Such as, the aluminium sheet after described degreasing process is implemented phosphoric acid chromic acid Ficus caricaL and form phosphoric acid chromic salt film.
(baking operation)
Baking processing is carried out for the aluminium sheet being coated with coating, makes the hardening of described coating and become hard coat film. Storing temperature is preferably more than 210 DEG C, less than 280 DEG C, if in such temperature range, then just can obtain hard coat film with the baking processing of the short period of time of 20��60 seconds. Further, storing temperature is that being up to of aluminium sheet reaches temperature. When the baking processing time was lower than 20 seconds, toasting likely insufficient, on the other hand, under this storing temperature, even if baking processing was more than 60 seconds, also can not harden further, the productivity of unit time reduces. In addition, when storing temperature is lower than 210 DEG C, under the baking processing in 20 seconds, the hardening of coating is insufficient, and the hardness of hard coat film is insufficient. More preferably storing temperature is more than 230 DEG C, and the baking processing time is 20��50 seconds. Baking processing according to the high temperature compared like this, it is easy to formed and there is C, C triple bond and C, the resin of N triple bond. If but storing temperature is more than 280 DEG C, then coating starts to decompose, and therefore the hardness of hard coat film reduces on the contrary. Or storing temperature lower than 210 DEG C time, carry out long-time baking processing and also can obtain hard coat film. Specifically, if the baking processing time is 1 hour, then storing temperature can be made to be 130 DEG C, make storing temperature be 150 DEG C in addition, then can be formed and there is C, C triple bond and C, the resin of N triple bond. Baking processing can use hotblast stove, induction heater, near infrared ray stove, far infrared stove, energy line tempering stove etc. to carry out.
