Description

The present invention relates to metal and non-metal surface layer structures. In particular, the present invention relates to a surface layer structure obtained by coating a surface of an acrylic layer by plating a metal layer on a workpiece surface by vacuum plating and performing an electrodeposition process.

The surface of commonly seen items and tools such as drawers, door handles or locks is generally treated with a special surface treatment and is plated to improve the durability and appearance of the item. There are many cases. In general plating, first, the workpiece is washed with a strong acid solution, the dust on the surface is removed, the metal is placed in the plating tank, a current is passed, the work is placed in the plating tank, and the current is ionized. A plating layer is formed by adhering a raw material metal to a workpiece, and finally, a baked paint is applied to the surface of the plating layer to form a protective layer.

However, this has the following drawbacks.
(B) Conventional plating requires the use of a large amount of chemical solution. If no waste liquid treatment equipment is used, the highly corrosive chemical solution has an adverse effect on the environment, and even if the waste liquid treatment equipment is used, the environment It was not possible to eliminate the adverse effects on

(B) Since plating attracts the raw metal by an electric current and adheres to the workpiece surface, the plating can be performed only with a conductive workpiece.

(C) In general, the plated workpiece is spray-coated on the surface in order to prevent peeling of the plating layer and improve the corrosion resistance. However, the corrosion resistance effect of the paint is not good and the paint cannot be uniformly applied to the workpiece surface, so that the overall corrosion resistance effect is not good.

(2) Since the plated layer of the workpiece is extremely thin, the workpiece on the workpiece surface has a sharper shape, does not feel soft, and the workpiece treated with the baked paint does not have good wear resistance and gloss.

(E) Conventional plating requires the use of a large amount of corrosive chemical solution and a large amount of waste liquid is generated, so it is necessary to install waste liquid treatment equipment, but the purchase price of the equipment is extremely high. In order to increase the manufacturing cost of the product and improve the rust prevention effect, first, copper is plated on the workpiece surface, then nickel is plated and then silver is plated. However, such a plating process is extremely complicated. As a result, the manufacturing cost increases significantly.

The workpiece to be surface-treated is hung on a conductive fixed support frame, and the bottom film that smoothes the surface of the workpiece is spray-coated on the workpiece surface, and the vacuum plating step is fixed to the workpiece with the bottom film spray-coated. The support frame is installed in a stereotaxic plate of a vacuum plating furnace, and the plating furnace is evacuated to allow current to flow, thereby depositing a plated metal layer on the surface. In the electrodeposition step, the plated metal layer is adhered to the surface. By placing the work and fixed support frame in the electrodeposition bath containing the electrodeposition liquid, the electrodeposition liquid containing ions adheres to the work surface, and a thin film having a corrosion resistance effect is formed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 to FIG. 6 will be referred to. A workpiece surface treatment method according to the metal and non-metal surface layer structure of the present invention, wherein a localization step of the workpiece 20, a coating step of the bottom film 50, a drying step, a vacuum plating step, an electrodeposition step, It has steps such as a baking step and a workpiece lowering step.

The positioning step of the workpiece 20 is provided with a plurality of fixed support frames 10, and fixed portions 11 are provided at both ends of the fixed support frame 10, and a claw-shaped support rod 12 is provided at the middle stage of the fixed support frame 10. As shown in FIG. 2 and FIG. 3, the workpiece 20 is hung on the support rod 12 one by one and fixed.

In the application step of the bottom film 50, the plurality of fixed support frames 10 on which the work 20 is suspended are fixed at specific positions, and the bottom film 50 on which metal particles can easily adhere to the surface of the work 20 is spray-coated.

In the drying step, the bottom film is dried and cured by putting the workpiece 20 coated with the bottom film into a drying facility together with the fixed support frame 10 and baking it.

In the vacuum plating step, as shown in FIG. 4, the work 20 coated with the bottom film 50 and dried is put together with the fixed support frame 10 into a vacuum plating furnace 30, and the vacuum plating furnace 30 is a sealed furnace. A positioning plate 31 for fixing the fixed support frame 10 is provided on one of the insides, and a power supply set 300 is provided on the other side. The power supply set 300 mainly includes two electrode rods 32. A tungsten wire 33 is connected between the electrode rods 32, and a raw metal 34 is wound around the outer circumference of the tungsten wire 33. An electric current is passed through the electrode rod 32 to raise the temperature of the tungsten wire 33, and as a result, the raw metal 34 on the tungsten wire 33 becomes fine particles and adheres to the bottom film 50 on the surface of the workpiece 20. To form a layer 51.

In the electrodeposition step, as shown in FIG. 5, the vacuum-plated work 20 is transported to the electrodeposition location together with the fixed support frame 10, and the fixed support frame is placed in the electrodeposition tank 40 containing the acrylic electrodeposition liquid 41. 10 and the work 20 are installed, and the work 20 and the fixed support frame 10 are conductive, so that the acrylic electrodeposition liquid 41 having ions adheres to the surface of the work 20, and thereby the corrosion resistance effect is extremely good. An acrylic film 52 is formed.

In the baking step, the workpiece 20 that has been subjected to the electrodeposition treatment is placed in an oven together with the fixed support frame 10 and heated to cure the acrylic film 52.

In the workpiece lowering step, each workpiece 20 is lowered from the support rod 12 of the fixed support frame 10. By doing so, the surface treatment is completed.

A metal plating layer 51 is formed on the surface. When manufacturing the metal and non-metal surface layer structures of the present invention, vacuum plating is used and no chemical solution is used, so there is no risk of environmental pollution.

In addition, the metal and non-metal surface layer structure of the present invention can perform the plating operation by applying the bottom film 50 to the surface of the metal or non-metal workpiece 20, so Since it can be applied to the metal workpiece 20 and the electrodeposition work cannot be performed unless it is a conductive material, a plated metal layer 51 is formed on the surface of the non-metal workpiece 20 after vacuum plating. Since the plated metal layer 51 of the work 20 comes into contact with the fixed support frame 10, when the vacuum-plated work 20 is placed in the electrodeposition tank 40 together with the fixed support frame 10, acrylic ions in the electrodeposition liquid 41 are removed. An acrylic layer 52 is formed by adhering to the metal of the plating layer. Since the dried acrylic layer 52 is extremely hard, its wear and corrosion resistance is far superior to a baked surface. Therefore, by forming a bottom film 50, a plated metal layer 51, and an acrylic layer 52 in this order on the surface of the workpiece 20 according to the present invention, as shown in FIG. Improved in properties and gloss.
