JPH05171401A - Method for metallizing surface of craftwork - Google Patents

Abstract

PURPOSE:To increase the adhesive strength of metal and to produce a rigid, lightweight, safe and metallic-looking craftwork at the time of producing the craftwork obtained by depositing a metallic coating film on the surface of a ceramic, etc., by forming an org. resin coating film on the surface before metal is sprayed. CONSTITUTION:A craftwork is shaped with argil, etc., and fired to obtain an unglazed craftwork 2. A primer of a resin contg. epoxy copolymer is then uniformly applied on the outer surface to form a substrate film 3. A metallic grain is sprayed on the dried substrate film with an arc spraying machine to form a metallic film 4. A waterproof paint is sprayed to the inside, if necessary, to form a waterproof film 5 in a case of flower vase, etc. A metallic-looking craftwork 1 is obtained in this way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a strong, lightweight and inexpensive metal-look arts and crafts such as statues and vases.

[0002]

2. Description of the Related Art A metal craft product is made by first forming an original shape, using it to make a mold or core, and injecting molten metal into the casting. After cooling, the product was taken out of the mold and the burrs and other defective parts were corrected and processed into a product.

[0003]

Therefore, it takes a lot of man-hours, a large amount of expensive metal materials are required, and the weight is heavy and the transportation and handling thereof are difficult. Therefore, many of them are expensive and not common. The object of the present invention is to eliminate these drawbacks, and to provide at low cost a metal-look craft that is lightweight, durable, and has the appearance of being entirely made of metal. It is what

[0004]

[Means for Solving the Problem] A hard organic resin coating is formed on the surface of a clay mold, unglazed mold, lightweight concrete, mold made of gypsum, etc. or wood carved mold After that, a metal or a metal alloy is sprayed by an arc spraying method under reduced pressure. In this way, a metal look craft is produced.

[0005]

In the present invention, since the hard organic resin coating is formed on the clay and other molds, the coating protects the rubbed material, and at the same time protects the prototype against arc spraying, the metal The adhesion is increased, the adhesion of the metal coating is improved, and the coating is less likely to peel off. Therefore, increasing the overall strength,
Improves impact resistance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the drawings. FIG. 1 is an external view of a vase which is an example of a craft product created according to the present invention. 2 (a) is the vase of FIG.
FIG. FIG. 2B is an enlarged view of a part thereof. FIG. 3 is a cross-sectional view of the nozzle portion used in the reduced pressure arc spraying method. In the figure, 1 is a vase. 2 is the clay material section. Three
Is a film of organic resin, which firmly adheres the metal to the porcelain clay material portion 2. The organic resin preferably contains an epoxy copolymer. 4 is a metal coating. 5 is a waterproof coating, which can be any paint that creates a waterproof coating. 6 is a nozzle used for arc spraying in reduced pressure. , 7 are wire readers, 2
Positioning the wire 8 of the book, the wire 8 is fed through it. Reference numeral 8 is a wire, which is made of metal to be attached. Copper, copper alloy, aluminum, zinc, titanium, etc. are available. Reference numeral 9 is an arc point, and an arc is generated by the two wires 8. 10 is a nozzle hole. , 11 is the jet air flow,
Generated by the compressed air introduced inside the nozzle, the metal particles in the arc are blown onto the object.

Next, the manufacturing method of the present invention will be described. First, a craft product, for example, a vase is formed from clay and fired to make the unglazed vase 1. Next, an undercoat paint of a resin containing an epoxy copolymer is uniformly applied to the outer surface to form a base film 3.
Dry for a predetermined time. When the drying is completed, metal particles are sprayed using a metal arc spraying machine to form the metal coating 4. The structure of the nozzle 6 of the thermal spraying machine is as shown in FIG. 3. Inside the nozzle 6, there are two wire leaders 7 that support two wires 8 so that they intersect at a predetermined position, an arc point 9. By energizing the wire 8,
The arc flies at the arc point 9 and the wire 8 in the arc
The metal of the material is a particle having a diameter of 5 to 150 μ.
This is jetted from the nozzle hole 10 by the compressed air introduced into the nozzle, and the metal particles are jetted as a jet stream 11. This jet stream 11 is applied to the vase to form the coating film 4 having a uniform thickness on the entire surface. In this way, the high-speed metal particles bite into the hardened resin, so that the adhesive force of the metal coating becomes strong and the metal film does not come off. Since the wire 8 becomes particles sequentially and scatters and decreases, it is fed at a constant speed. In the case of a vase, water is put inside, so paint a waterproof paint inside,
The waterproof coating 5 is applied. Not required for statues and other cases. The outer metal coating 4 can be polished to give a glossy surface as if plated. Also,
Appropriate treatment, such as when copper is used, produces patina, which can be made into a quaint vintage craft. Statues of materials such as lightweight concrete, gypsum or wood, and figurines can be manufactured in the same manner. Although it is considered as a craft here, it goes without saying that daily commodities are also included.

[0008]

Since the present invention is manufactured as described above, since metal particles bite into the hardened resin, the material such as porcelain clay, gypsum or wood adheres to the metal, and there is no fear of peeling, and it is made of all metal. You can make crafts that are much lighter and cheaper than the ones.
