Abstract
The present invention relates to a process for making visually contrasting structures on a metallic substrate , characterized in that the substrate which is coated with a single coloured layer is partially subjected to the energy of a laser beam in such a way that a transparent remainder of the layer is maintained on the treated area; a metallic substrate which is provided with visually contrasting structures, characterized in that a single coloured layer is present on part of the substrate, while on the remaining part of the substrate in place of this layer a single transparent layer which is substantially thinner as compared to the single coloured layer is present.
Description
The present invention relates to the metal base that the surface has different visible color zone, this metal base is suitable for making or the container of processing beverage bucket and so on.
Now, mode below the general using is being made sign with two kinds of colors, label etc. on the metal base: apply upper and lower two-layer epoxy resin enamelled coating with different colours on this metal base respectively, utilize laser ablation then, the enamelled coating that will be positioned at the superiors is partly removed, thereby the enamelled coating in some the superiors has been removed the zone that evaporates in other words, and the enamelled coating with another color that is positioned at the bottom is come out.
The cost of this method is very high because on metal base the process of coated with resins (paint), need in dividing other workflow, carry out twice.For for example being tabular or the base material of sheet, this flow process is very long and loaded down with trivial details, this is because because before the paint of coating equipment a kind of different colours under applying, must be by thoroughly cleaning is clean, therefore before second layer coating subsequently, equipment has to supspend work, and this greatly reduces the production efficiency of whole production line.But, up to now till, also nobody proposes a kind of better method that on a large scale lacquer of two kinds of different colours is coated on the metal base.
The objective of the invention is to propose a kind of, than existing, faster, cost is the lowland large scale production method more.
Purpose of the present invention passes through only to apply unique one deck nonferrous layer on metal base, and selecting the zone, utilizes laser ablation, and the thickness of this nonferrous layer of attenuate (evaporation) is finished.Have found that, utilize low power laser treatment one nonferrous layer of comparing with existing method, can this nonferrous layer of attenuate, make it the clear-coated film of the very thin shape of film in other words of only remaining one deck, because this layer coat film is translucent, therefore the color of metal base itself can display, thereby presents multiple different color on whole base material.
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 shows method of the present invention and final products.Figure 1A shows that wherein base material 1 is coated with a nonferrous layer 2 fully before laser ablation; Figure 1B shows, an appointed area 4, after by laser ablation these nonferrous layer 2 parts being evaporated, produces the hyaline layer that stays 3 that thickness is significantly smaller than nonferrous layer 2.
Figure 2 shows that the existing method mentioned in this paper front.Opposite with the present invention, shown in Fig. 2 A, under first nonferrous layer 2 ', comprise also that on this metal base 1 ' another one has second nonferrous layer 5 ' of different colours, this nonferrous layer 5 ' directly is coated on the base material.Shown in Fig. 2 B, the irradiation of laser beam causes being evaporated fully at the processed regional 4 ' nonferrous layer of locating 2 ', and most of thickness of second nonferrous layer 5 ' then is retained, thereby locates in zone 4 ', and the color of the second layer 5 ' is displayed.
In general, the thickness of nonferrous layer is optional, and depends on known consideration (intensity of anti-indentation, price or the like).In the prior art, the thickness of bottom nonferrous layer is generally about 3-4um, and superposed nonferrous layer thinner (for example at 0.5-2um), and unique one deck nonferrous layer of the present invention, can be for example identical or thinner slightly (for example approximately 2-4um, be preferably) less than 3um with the thickness of nonferrous layer in the existing method.By laser ablation, remaining is extremely thin one deck (remaining thickness is between the original 1/6-1/3).The nonferrous layer that is 3um for a thickness for example, through behind the laser ablation, remaining layer thickness that can be transparent is 0.6um.
In the method according to this invention, can adopt traditional laser ablation mode.For example obtain with the dot matrix mode of printing, letter, individual character, icon, pattern etc. are covered or the cuticula that only they come out or template are covered after on the metal base, carry out laser ablation.Needed laser power depends on the thickness of coat, and those of ordinary skill in the art fully can calculate.Certainly, powerful laser ablation can be removed the coat of big thickness.Than removing superposed coat in the prior art, the needed laser energy of coat that the present invention is unique even under situation about being of uniform thickness, also can significantly reduce.Therefore.For the present invention, use nitric oxide (NO) laser instrument can reach goal of the invention fully.The needed laser power of method of the present invention is, in zone selected, that expose, most of thickness of nonferrous layer is removed, thereby make one deck that stay, very thin become more transparent, therefore the color of metal base is able to come out as another color, thereby, like metallic substrate surface well and had two kinds of colors.
Utilize method of the present invention can produce the layer that stays of an actual transparency really, this fact can draw by the experience of utilizing copper sulphate to handle base material fully.
Unique one deck nonferrous layer can constitute by applying general for example epoxy resin shape paint.As for color, without any restriction, black is relatively good because this color can and the translucent background color of metal base (for example aluminium, steel) constitute contrast.
Because laser ablation of the present invention does not all evaporate the nonferrous layer composition of exposed region; so one deck colorless film that stay, very thin; can be used as protective layer protects metal base not to be subjected to the erosion of air; and as the barrier layer; resist of the erosion of other material to metal base; and, prevent that metal from getting rusty as overcoat.
The method according to this invention can be passed through a simple mode, produces novel metallic sheet, and this metallic sheet is anticorrosion and have a beautiful external form.Method of the present invention is except can being used to produce the planar metal base material, can also be used to produce canister, this canister can be to utilize method of the present invention to apply after moulding, also can be to utilize method of the present invention to apply back reshaping afterwards.As a kind of selection, also can be to utilize method of the present invention to handle in the specific region of container or bucket, for example the bottom of container or the draw ring of Beverage pail (perhaps being referred to as " pulling-on piece ") are handled, thereby on the back side of for example draw ring, can form a very little mark, with as distinguishing mark of the producer or internal staff etc.
