Description
COATING STRUCTURE FORMED ON AN ALUMINUM WHEEL AND
A FORMING METHOD THEREFOR
The present invention relates to a coating structure formed on a wheel made from aluminum or aluminum alloy (hereinafter, an aluminum wheel) and a method for forming the coating structure.
A coating structure is formed on an aluminum wheel at its fashion or visible surface which includes a machined, front surface of the wheel and a non-machined, inside surface defining a ventilation hole of the wheel.
For the aluminum wheel coating, a smooth feeling is required at the non-machined surface of the fashion surface to provide a high-class design feeling. Further, formation of a stable coating film with a relatively great thickness is required at an edge portion of the wheel between the front surface and the inside surface of a ventilation hole to effectively prevent the generation of corrosion.
There are two conventional methods to provide a smooth feeling at the non-machined surface of the wheel.
One is a method wherein two kinds of shot blasts using coarse cut wire pieces and using fine cut wires pieces are conducted to obtain a smooth surface, and the other is a method wherein a plurality of acryl-based colour paints containing organic solvent are coated one on top of another to fill concavities of the molded rugged surface.
As a method to form a stable coating layer on the edge portion between the machined surface and the nonmachined surface, the edge portion is chamfered after machining the front surface of the wheel, and then a plurality of acryl-based colour paints are coated on the chamfered surface.
However, the above-described conventional methods have the following problems.
The method where shot blasts are conducted twice requires a double-sized equipment and a double consumption of a cut wire, which is accompanied by a cost increase.
The method where a plurality of paints are coated one on top of another takes a long time, which lowers efficiency of production. Further, it is difficult to obtain a sufficient thickness of coating layer at a vertical surface because paint runs along the vertical surface.
The method where the edge portion is chamfered and then a plurality of paints are coated requires a chamfering step, which lowers efficiency of production.
An object of the present invention is to provide a coating structure and a forming method there for which can provide a smooth feeling at a non-machined surface and a stable coating layer with a relatively large thickness at an edge portion without being accompanied by a decrease in production efficiency or an increase in cost.
According to the invention there is provided a coating structure formed on an aluminum wheel having a visible surface including a machined surface and a nonmachined surface connected to the machined surface via an edge portion. The coating structure includes (a) a polyester-polyurethane hybrid coating primer layer formed on at least the non-machined surface, (b) an acryl-based colour coating layer formed on the primer layer, and (c) a clear coating layer formed over the entirety of the visible surface. The clear coating layer is coated on the colour coating layer at the portion of the aluminum wheel where the colour coating layer is formed.
A method for forming a coating structure on an aluminum wheel is also provided.
Hybrid primers containing polyester and polyurethane polymers are known. Polyester-methane hybrid primers may also be used. As the colour coating layer there is used an acryl-based coating material, i.e.
a polymer based on acrylic acid or a derivative of acrylic acid, for example an acrylamide polymer or an acrylate polymer such as a polymethacrylate. The clear coating layer can be any suitable material, but is preferably an acryl-glycidyl based resin layer, e.g. a glycidyl methacrylate type.
The above and other optional features, and advantages of the present invention will become more apparent and will be more readily appreciated from the following detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings, in which:
Fig. 1 is a cross-sectional view of an aluminum wheel on which a coating structure according to any embodiment of the present invention is formed;
Fig. 2 is a partial cross-sectional view of a coating structure, encircled by Circle E in Fig. 1, according to a first embodiment of the present invention; and
Fig. 3 is a partial cross-sectional view of a coating structure encircled by Circle E in Fig. 1, according to a second embodiment of the present invention.
Fig. 1 illustrates a cross-section of a molded aluminum wheel 1 having a fashion surface which includes a front surface 2 (a surface that can be seen from outside when a wheel is mounted to an automobile) and surfaces defining a plurality of ventilation holes 3. In
Figs. 2 and 3, reference numeral 10 shows a material of the aluminum wheel. The front surface 2 is machined to form a machined surface 11, and an inside surface of each ventilation hole 3 forms a non-machined surface 12, namely, a molded surface. The machined surface 11 and the non-machined surface 12 are connected to each other via an edge portion 4. A coating is formed on the fashion surface of the wheel 1. The coating provides a smooth feeling at the non-machined surface 12. A stable coating film having a relatively great thickness is required at the edge portion 4.
Fig. 2 illustrates a coating structure according to a first embodiment of the present invention, and Fig. 3 illustrates a coating structure according to a second embodiment of the present invention. In the first embodiment of the present invention, the entire fashion surface of the aluminum wheel 1 is coated with a coating having a three-layer structure. In the second embodiment of the present invention, the non-machined inside surface 12 of the ventilation hole 3 is coated with a coating having a three-layer structure and the machined front surface 11 is coated with a coating having a single-layer structure. Structural portions common to the first embodiment and the second embodiment are denoted with the same reference numerals throughout the description of the first embodiment and the second embodiment.
First, the structural portions common to the first embodiment and the second embodiment of the present invention will be explained with reference to, for example, Fig. 2.
A coating structure formed on the fashion surface of the aluminum wheel 1 according to this embodiment of the present invention includes a polyester-polyurethanehybrid primer layer 13 formed on at least the nonmachined surface 12, and acryl-based colour coating layer 14 formed on the primer layer 13, and an acryl-glycidylbased clear coating layer 15 formed over the entire fashion surface. The acryl-glycidyl-based coating layer 15 is coated on the colour layer 14 at a portion of the aluminum wheel 1 where the colour coating layer 14 is formed.
The reason why the polyester-polyurethane paint is used as the primer layer 13 is that the polyesterpolyurethane coating layer 13 is superior to an epoxy polyester-based hybrid coating from the viewpoint of weather-resistance and that the polyester-polyurethane coating layer 13 does not cause a problem of health during coating unlike a polyester-glycidyl compound coating layer.
The polyester-polyurethane coating primer layer 13 has a thickness of approximately 50 - 100 ym. After coating, the primer coating is baked at about 180 - 200 C for about 15 - 20 minutes. The baked primer layer 13 has a hardness of about H - 3H in pencil hardness. In this connection, the layer thickness of about 50 Um or more is a thickness preferred, in order to fill concavities of the rugged, non-machined molded surface, and the layer thickness of about 100 Hm or smaller is a thickness determined from the viewpoint that more paint will be consumed without showing great surface-smoothing effect above 100 ym. As the polyester-polyurethane paint, for example, VP-1484 produced by Ferro (Michigan, USA) can be used.
The acryl-based colour coating layer 14 has a thickness of about 15 - 30 ym. After coating, the solvent colour coating is baked at about 120 - 140*C for 15 - 25 minutes. The baked colour coating layer 14 has a hardness of H - 3H in pencil hardness. The thickness of 15 jtm or more is a thickness preferred to hide the colour of the under surface, and the thickness of 30 ym is a thickness determined from the viewpoint that more paint will be consumed without showing a great hiding effect above 30 tjm. The colour may be selected as any colour so as to satisfy a client demand, for example, grey, gold and silver. As a acryl-based colour paint containing organic solvent, for example, JTAW 49515 produced by PPG can be used.
The acryl-glycidyl-based clear coating layer 15 has a thickness of about 40 - 120 ijm. After coating, this layer is baked at 170 - 185it for 15 - 25 minutes. The baked acryl-glycidyl-based coating layer 15 has a thickness of H - 3H in pencil hardness. The thickness of about 40 ym or more is a thickness preferred to ensure a stable thickness (20 ym or more) at the edge portion 4 by the top clear layer 15 only, and the thickness of about 120 iim is a thickness determined from the viewpoint that more paint will be consumed without showing a great barrier effect at the entire fashion surface including the edge portion 4. As the acryl-glycidyl-based clear coating paint, for example, 158C121 produced by Ferro (a glycidyl methacrylate resin based coating cured with a diacid cross linker) can be used.
A coating structure unique to each embodiment of the present invention and a forming method therefor will now be explained.
The coating structure formed on the aluminum wheel according to the first embodiment of the present invention is a colour coating structure. As illustrated in Fig. 2, in the colour coating structure, the primer layer 13 is formed on both the non-machined, molded surface 12 and the machined surface 11.
Therefore, the coating structure is a three-layer structure including the polyester-polyurethane hybrid primer layer 13, the acryl-based colour layer 14 formed on the layer 13, and the acryl-glycidyl-based clear layer 15 formed on the layer 14, which is formed on both the machined surface 11 and the non-machined surface 12. In this coating structure, a coating film having the thickness of 40 ym or more is formed at the edge portion 4. Formation of the coating structure is conducted after machining the front surface 2 of the aluminum wheel 1.
