BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite product having a hard metal surface formed by thermal spraying, the back surface of which is reinforced with a fiber reinforced resin or the like, a method for producing such a composite product, and The present invention relates to a release agent used in this production method. The composite product is used for arts and crafts such as reliefs and images having a metal surface appearance, decorations, flooring materials requiring abrasion resistance, and resin molding dies.

2. Description of the Related Art Fiber reinforced resin (hereinafter referred to as FRP)
Is lightweight, has high strength, and is excellent in heat resistance and weather resistance, so that it has come to be used in a wide range even in the field where metal materials have been conventionally used. However,
The surface hardness of FRP is lower than that of metal or the like. Therefore, when it is used for applications requiring high surface durability, such as flooring materials and resin molding dies, the surface tends to become cracked or worn, making it unusable. It was rare.

In the field of arts and crafts, FR
On the surface of an article made of P or a resin containing no fiber,
It has been practiced to form a metal coating by metal spraying to give a metal-like appearance. However, in this case, since the metal surface sprayed on the surface of the article is a rough surface, a surface polishing step was required to obtain a beautiful glossy surface. Further, in order to form a fine uneven pattern on the metal surface, it is necessary to perform cutting by hand engraving or the like after polishing, which requires a lot of labor and technology. Here, in this specification,
The “(fine) uneven pattern” means a pattern generated by (fine) unevenness.

Therefore, the following method has been proposed. That is, a mold release agent made of PVA resin or the like is applied to the surface of a master made of wood or gypsum. Then Zn and Zn-A
Spraying a relatively soft metal having a low melting point, such as an alloy. The back surface of this sprayed metal layer is reinforced with a reinforcing layer such as fiber reinforced resin. The obtained composite body including the sprayed metal layer and the reinforcing layer is released from the original mold. In this way, it is possible to manufacture a composite product in which the surface shape of the prototype is transferred to the surface of the sprayed metal layer. If this method, the surface shape of the prototype, the surface of the sprayed metal layer,
It is possible to accurately transfer even fine uneven patterns. Further, the surface hardness, which is a weak point of FRP, can be improved. Such a technique is disclosed in, for example, JP-A-60-121022.

However, although Zn or the like which has been generally used as a sprayed metal in the past is suitable for transferring a prototype shape by spraying, it has low hardness and poor wear resistance. Therefore, it has not been sufficiently satisfactory for the use requiring the mechanical strength and other properties of the molding die described above.
Therefore, it is required to use a metal having excellent various characteristics such as nickel and stainless steel as the sprayed metal.

However, nickel and stainless steel have a high melting point, and there is a problem that they do not adhere sufficiently even if they are sprayed onto the surface of the master. Further, there is a drawback that the fine unevenness pattern formed on the surface of the master cannot be accurately transferred, and the reproducibility of the unevenness pattern is poor.

Conventionally, a method for producing a good composite product composed of a sprayed metal layer and FRP by the above-mentioned transfer method using a high melting point metal such as nickel or stainless steel has been proposed.
Various proposals have been made.

For example, it is known that if fine irregularities are formed on the surface of the master by blasting or the like, the adhesion of the high melting point sprayed metal layer is improved.

Japanese Patent Publication No. 61-61891 discloses the following technique. First, make a model with wood or plaster. An inversion type of the above model is made of a heat resistant resin such as silicon rubber. Using this inversion type, antimony or the like having a high melting point and less likely to expand is precision cast to produce a second model having the same shape as the above model. After implanting a pin made of refractory metal on the surface of the second model, the refractory metal is sprayed. The back of the refractory metal is reinforced with silica sand. Second
If the model is melted and removed and the pins are also removed, a surface shape inverted from the initial model is formed on the surface of the high melting point sprayed metal layer. According to this method, the pins implanted in the second model made of refractory metal enhance the adhesion of the refractory metal.

In Japanese Examined Patent Publication No. 63-6327, a prototype made of a material such as wood and plastic that is easy to process,
After applying a water-soluble adhesive such as water glass and a surface treatment agent mainly composed of red iron oxide, nickel or chrome is sprayed by room temperature metal spraying. Here, in this specification, "normal temperature metal spraying" means a thermal spraying method in which the temperature of the master does not rise even if the hot metal melted at high temperature is sprayed onto the master. The surface shape of the prototype is transferred to the metal coating layer formed by this room temperature metal spraying. It is said that the mold release property is enhanced by using the surface treatment agent, and that the mold which is weak to heat can be used by performing thermal spraying at room temperature.

Japanese Patent Publication No. 2-23331 discloses a technique of using a silicone elastomer containing a refractory filler such as quartz as a surface material of a prototype. The refractory filler is said to prevent the adverse effects of heat during thermal spraying.

In Japanese Patent Publication No. 2-54422, when a metal is sprayed directly on the surface of a product substrate, a composition containing a fine particle material in a resin is applied to the surface of the product substrate. As a result, there is disclosed a technique for directly improving the adhesion of the sprayed metal layer formed by thermal spraying.

[0013]

However, in the above-mentioned prior art, the adhesion of the high melting point sprayed metal is not yet sufficient, and the reproducibility of the surface shape of the prototype is inferior.

For example, in the method of uniformly forming fine irregularities on the entire surface of the master by blasting or the like, when the master has fine irregularities, the fine irregularities are erased. , It is not possible to transfer a fine uneven pattern to the surface of the high melting point sprayed metal layer. Therefore, in this case, an uneven pattern is post-processed on the surface of the obtained high melting point sprayed metal layer by hand engraving or etching. Therefore, it takes time and cost for processing. Further, it is impossible to form the same fine concavo-convex pattern as in the prototype model by post-processing, and the quality of the finished product varies greatly. further,
When the blasting is performed, the surface of the high melting point sprayed metal layer cannot be finished to be a mirror surface, and when the product surface needs a mirror surface, it is necessary to perform a mirror surface processing such as polishing as a post-processing.

The technique disclosed in Japanese Examined Patent Publication No. 61-61891 requires the work of cutting the pin and the work of erasing the mark of the pin by polishing or the like. Therefore, it is not possible to form a fine uneven pattern in the place where the pin is installed. Polishing work to erase the traces of the pins erases the fine uneven patterns.
At a position away from the place where the pin is installed, the pin does not have the effect of improving the adhesiveness. Therefore, the blasting process described above is required at such a place, and there is the same problem as described above. Further, in this method, the thermal spraying of refractory metal is
This is the second model formed by precision casting from antimony or the like, but this precision casting method requires extremely high technology and takes a long processing time. Moreover, in order to manufacture the second model by precision casting, it is necessary to manufacture a heat-resistant reversal mold such as silicon rubber from a model such as gypsum, and the manufacturing process of the reversal mold also takes time and time. .

According to the technique disclosed in Japanese Patent Publication No. 63-6327,
In order to use a wooden mold or gypsum that is easy to process but weak against heat as the prototype, the room temperature metal spraying method is adopted.In this room temperature metal spraying method, the surface of the formed high melting point sprayed metal layer is However, it becomes a surface having rough unevenness like ground glass. Therefore, even if a fine relief pattern is formed on the master, the fine relief pattern is not transferred to the surface of the high melting point sprayed metal layer. It is noted in the publication that the prototype can be formed of a metal having a low melting point and easily processed. However, as in the case of the above-mentioned Japanese Patent Publication No. 61-61891, it takes a lot of labor and cost to manufacture a master mold made of such a metal.

According to the technique disclosed in Japanese Patent Publication No. 2-23331,
Since the mechanical strength of a silicone elastomer spraying a high melting point metal and the characteristics as a mold are considerably inferior to those of a mold, a good high melting point sprayed metal layer cannot be formed. Therefore, in the technique of the publication, the surface of the silicone elastomer is roughened to enhance the adhesion of the high melting point sprayed metal layer, or the surface of the silicone elastomer is thinly sprayed with a high melting point metal such as Zn / Al alloy. It is said that it is preferable to put it. However, if the surface of the silicone elastomer is roughened, the fine uneven pattern disappears. Further, if the refractory metal is sprayed on the surface of the silicon-elastomer, the surface of the refractory metal becomes an irregular uneven surface, and the fine uneven pattern of the prototype is filled and disappears. Moreover, when the refractory metal is sprayed directly on the refractory metal, when the refractory metal layer is released from the surface of the silicone elastomer, the refractory metal spray layer is formed on the surface of the refractory metal layer. It remains adhered and a product having a high melting point sprayed metal layer on the surface cannot be obtained.

According to the technique disclosed in Japanese Patent Publication No. 2-54422,
Although the adhesion of the sprayed metal layer to the base material becomes good, it is difficult to peel the sprayed metal layer from the surface of the base material. Therefore, it cannot be applied to a method of forming the sprayed metal layer on the surface of the master, releasing the sprayed metal layer from the master, and transferring the surface shape of the master to the sprayed metal layer.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a composite product having a high melting point sprayed metal layer and a reinforcing resin layer, which has excellent surface shape and characteristics. To provide. In addition, as a method for producing the composite product as described above, it is to provide a method excellent in the adhesiveness of the high melting point sprayed metal layer and the reproducibility of the surface shape including the fine concavo-convex pattern and the mirror surface of the prototype. . A further object of the present invention is to provide a release agent used in the above-mentioned production method, which can further enhance the above-mentioned effects.

[0020]

A composite product having a sprayed metal layer according to the present invention, which solves the above problems, is a metal layer formed by spraying and a resin for reinforcing the sprayed metal layer from the back surface. In the composite with the layer, the sprayed metal layer is made of a high melting point metal having a melting point of 1000 ° C. or higher, and the same fine unevenness pattern as that of the surface of the production master is transferred to the surface of the high melting point sprayed metal layer. .

The method for producing a composite product having a sprayed metal layer according to the present invention is a method for producing a composite product of a metal layer formed by spraying and a resin layer for reinforcing the sprayed metal layer from the back surface. That is, first, a prototype having the same surface shape as the composite product to be manufactured is produced,
Next, after the mold release treatment is applied to the surface of this prototype, the melting point 1
A composite of a high melting point sprayed metal layer and a reinforcing resin layer is formed by spraying a high melting point metal of 000 ° C. or higher, reinforcing the back surface of the formed high melting point sprayed metal layer with a resin layer, and curing the reinforcing resin layer. The body is demolded from its original shape.

The prototype is an accurate representation of the surface shape of the composite product to be manufactured, including fine irregular patterns. Wood, gypsum, resin, metal or the like, which can easily be processed into fine uneven patterns, is used for the production of this prototype. The surface of a natural material such as a crushed surface of natural stone or a wood grain pattern can be directly used as a prototype. A leather grain pattern, a stitch pattern, a suede pattern can be formed on the surface of the metal material by etching, or the wood grain pattern or the like can be embossed. In the present invention, the above-described fine uneven pattern of the prototype is reproduced as it is on the surface of the composite product. The height, depth, or width of the fine uneven pattern varies depending on the purpose or design of the composite product, but in the present invention, the height or depth of the unevenness is 50 μm or less and the width is 50 μm or less. Even if
It can be accurately reproduced on the surface of the composite product.

After subjecting the surface of the prototype to a mold release treatment,
It is preferred to spray the metal. The mold release treatment is to make the sprayed metal layer easily separate from the surface of the master when releasing the sprayed metal layer from the master, and at the same time, ensure that the sprayed metal adheres to the surface of the master during spraying. Then, it is a process for allowing a good sprayed metal layer to be formed. In the release treatment, the inorganic particles have an average particle size of 0.1 to 20.
The first inorganic particles having μ and an average particle diameter of 0.05 to 5 μ
Which is a mixture with the second inorganic particles, wherein
The release agent treatment in which the average particle size of the inorganic particles is twice or more the average particle size of the second inorganic particles may be adopted, and a coating means such as spray coating can be used.

The smaller the particle size of the sprayed metal particles, the more accurately the fine uneven pattern can be transferred. Specifically, it is preferable to adjust the blowing air pressure and the like at the time of thermal spraying so that the particle size of the thermal spraying metal particles is about several μ to 100 μ.

A reinforcing layer such as fiber reinforced resin is formed on the back surface of the high melting point sprayed metal layer formed along the surface of the master.
The reinforcing layer is a resin-only layer containing no reinforcing fibers, other,
Any reinforcing material used in conventional FRP can be used. In this invention, it is preferable to use the fiber-reinforced resin described below.

The fiber reinforced resin comprises a thermosetting resin and a reinforced fiber. As the thermosetting resin, a usual resin material for fiber reinforced resin can be used, and for example, epoxy resin, unsaturated polyester resin, etc. are used. As the reinforcing fiber, a usual fiber material for fiber-reinforced resin can be used, and for example, glass fiber, carbon fiber, polyamide fiber or the like is used. When the workability is important, a combination of glass fiber and unsaturated polyester resin is preferable.

The thermosetting resin and the reinforcing fiber are laminated and cured on the back surface of the high melting point sprayed metal layer by a conventional method. At this time, if necessary, a reinforcing material such as an iron frame may be provided to prevent the warpage or deformation of the whole. After the resin is cured, the composite body composed of the fiber reinforced resin layer and the high melting point sprayed metal layer is released from the original mold.

If necessary, the surface of the produced composite body is washed to remove the release agent, and then the composite body is subjected to the next step of producing a final composite product.

As a releasing agent, an average particle size of 0.05 to 20 μm
Those obtained by dispersing the above inorganic particles in a volatile solvent, an inorganic binder such as water glass, or another dispersion medium are used. A release agent consisting of only inorganic particles that does not use a dispersion medium may be directly applied to the surface of the prototype. Examples of the inorganic particles include ferric oxide, nickel, molybdenum disulfide, graphite and the like. It is preferable that the inorganic particles have a melting point of 1000 ° C. or higher because they do not melt due to high heat during thermal spraying. Inorganic particles with irregular shapes on the outer shape are more
Good adhesion of the sprayed metal layer. In this respect, crushed red iron oxide raw material is more preferable than spherical red iron oxide (ferric oxide) used for paint.

A releasing agent can be obtained by dispersing the above-mentioned inorganic particles in a binder. Examples of the binder include water glass, a thermoplastic resin solution, a silicone resin, and a thermosetting resin such as an unsaturated polyester resin, an epoxy resin, and a urethane acrylate resin. The ratio of the binder to the inorganic particles is preferably about 20 to 200 parts by weight with respect to 100 parts by weight of the binder. If the amount of the inorganic particles is less than 20 parts by weight, the concavo-convex structure necessary for the adhesion of the high melting point sprayed metal layer is not sufficiently formed on the surface of the release agent applied to the master. Therefore, even if the high-melting-point metal is sprayed, it does not adhere well, and there is a concern that the high-melting-point sprayed metal layer may peel off. Further, when the amount of the inorganic particles exceeds 200 parts by weight, it becomes difficult to uniformly apply the release agent. Moreover,
Since the inorganic particles are not sufficiently fixed by the binder, the coating film of the release agent is peeled off by the impact at the time of thermal spraying.
As a result, the sprayed metal does not adhere well.

The release agent is applied to the surface of the master by a usual application means such as brush coating or spraying. In order to improve the workability of coating, it is preferable to dilute the release agent with water, a solvent or the like before use.

The inorganic particles have an average particle size of 0.1 to 20.
μ first inorganic particles and an average particle size of 0.05 to 5.0 μ
If a mixture with the second inorganic particles is used, the adhesion of the high melting point sprayed metal layer is improved. Further, it becomes possible to accurately reproduce the fine concavo-convex pattern on the surface of the prototype on the surface of the high melting point sprayed metal layer. In order to sufficiently exhibit the above effect, it is preferable that the average particle diameter of the first inorganic particles is twice or more the average particle diameter of the second inorganic particles. Furthermore, the first
It is preferable that the average particle diameter of the inorganic particles is 2.0 to 20 μm, and the average particle diameter of the second inorganic particles is 0.05 to 2.0 μm. As the first inorganic particles, ferric oxide, nickel or molybdenum disulfide is preferable, and two or more kinds may be mixed and used. As the second inorganic particles, scaly particles can exert more preferable performance than spherical particles. Boron nitride and graphite are preferable as the flaky inorganic particles, and both can be used together.

The following method can also be adopted as the mold release treatment.
That is, a liquid material in which relatively large inorganic particles having an average particle diameter of 0.1 to 20 μm are dispersed in a binder is applied to the surface of the prototype in the same manner as described above. After that, average particle size 0.0
Relatively small inorganic particles of 5 to 2.0 μ are attached from above the previously applied inorganic particle layer. Examples of the method for attaching the relatively small inorganic particles include, for example, a method of spraying the inorganic particles as a powder by spraying with air, or a method in which the inorganic particles are dispersed in a low-boiling point solvent that easily evaporates. Can be adopted.

The thickness of the coating formed when the release agent is applied to the surface of the master is preferably about 1 to 100 μm, and particularly 3 to 2 when transferring a fine uneven pattern.
It is desirable to set it to about 0 μ.

A refractory metal is sprayed onto the master mold which has been subjected to the mold release treatment by a usual metal spraying method. Flame spraying, arc spraying, plasma spraying or the like is adopted as the spraying method or spraying apparatus used at this time. However, the room temperature spraying method is not applicable because the adhesion of the high melting point metal sprayed layer is poor and it is difficult to transfer a fine uneven pattern. The arc spraying method is a preferable method because it can sufficiently exhibit the intended function of the present invention and has a small thermal effect on the master on which the high melting point sprayed metal layer is formed.

As the high melting point metal, any material can be used as long as it has a melting point of 1000 ° C. or more and can form a sprayed metal layer.
Specific examples include simple metals such as nickel, copper, iron, chromium and titanium, or alloys containing the above metals as main components such as stainless steel, nickel chromium, monel, nickel silver, brass and aluminum bronze. be able to. As the high melting point metal, a material having hardness, abrasion resistance, corrosion resistance, heat resistance and other characteristics is used according to the function and application required for the composite product.

The thickness of the high melting point sprayed metal layer depends on the intended use of the composite product. If only a metallic luster appearance is required, about 25 to 200 μ is sufficient. When high durability and abrasion resistance of the surface are required as in a molding die, it is desirable to set the film thickness to about 500 μ to 50 mm. Further, another low melting point metal can be superposed on the back surface of the high melting point sprayed metal layer and sprayed. Since the low melting point metal has little heat effect on the prototype during thermal spraying,
Can be sprayed quickly and in large quantities. Therefore, if the high melting point sprayed metal layer is formed to a thickness necessary for the surface characteristics and then the low melting point sprayed metal layer is lined, the workability can be improved without lowering the function or performance.

In the obtained composite product, the surface shape of the high melting point sprayed metal layer was exactly the same as that formed on the original mold, and the surface shape was exactly inverted. The pattern is also accurately reproduced. Therefore, the composite product can be used as it is as a final product, but if necessary, a part of the surface can be further polished or plated.

As a composite product, a resin product having a sprayed metal layer has been conventionally used for various purposes, for example, molding dies, arts and crafts, ornaments, other machine parts and building members. Can be freely applied to. The molding die may be, for example, one used for molding an HLU or the like, or one having a pair of male and female molds and used for casting, RTM, injection molding or the like.

The production of a prototype having an inverted surface shape of the composite product to be produced can be easily carried out by using ordinary techniques for producing a prototype for various moldings. The prototype is
It is possible to use a material such as resin, gypsum, or wood, which can easily be processed into a surface shape such as a fine uneven pattern.
Also, natural materials can be used as they are.

The composite product composed of the high melting point sprayed metal layer and the reinforcing resin layer produced as described above has a shape in which the surface shape of the high melting point sprayed metal layer is exactly the same as that of the prototype, that is, the production master. In particular, even a fine uneven pattern is accurately reproduced. This fine uneven pattern
Even a complicated irregular pattern of natural material, which is difficult to produce by mechanical cutting, can be easily formed.

When only small inorganic particles having an average particle size of 0.05 to 2.0 μ are used, the irregularities formed on the release agent coating become too small, and therefore, two types of particles having different particle sizes are used. The adhesion of the high melting point sprayed metal layer is inferior to the case of using the inorganic particles together.

On the other hand, when the above two kinds of inorganic particles are used in combination, a relatively large first inorganic particle and a relatively small second inorganic particle are divided into two stages and separately supplied to the surface of the master. If adopted, both inorganic particles are surely and uniformly supplied to the entire surface of the prototype. In addition, the gap between the relatively large first inorganic particles and the relatively small second
The inorganic particles can surely fill. as a result,
The adhesion of the high melting point sprayed metal layer described above is further improved.
