この発明はアイロンのペースや調理プレートのペースな
どとして使用される放熱ペースの製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing heat dissipating paste used as ironing paste, cooking plate pasting, etc.
一般にこの種の放熱ペースはその本体をアルミニウム合

プレートの調理面として使用するようにしている。Generally, the main body of this type of heat dissipation paste is made of aluminum alloy casting. The base surface of aluminum alloy castings is easily corroded, so the base surface is coated with a heat-resistant resin such as fluororesin to form a film layer, and the surface of this film layer is used as a surface for ironing or for cooking. I try to use it as a cooking surface for plates.

てしまうようなことがある。However, in order to apply such a film layer to the base surface of the pace body, the base surface must first be roughened by side blasting, degreased, and coated with a primer, and then coated with resin to coat it. Many processes such as heating and firing are often required. Even if a coating layer is formed through this process, the coating layer will wear out over long-term use, exposing the base surface of the aluminum alloy casting, and pinholes may occur during coating. Moisture may seep into the base surface through the holes, causing the base surface to corrode.

て平滑性が損なわれてしまうという不都合が生じる。Therefore, the present inventor considered attaching a stainless steel plate, which has no fear of wear or pinholes and has excellent corrosion resistance, to the base surface of the pace main body instead of the resin film layer. As a means of bonding, a stainless steel plate was previously assembled in a mold for pace forming, and an aluminum alloy was cast into the mold in this state, thereby bonding the stainless steel plate to the aluminum alloy casting. However, the melting point of the stainless steel plate is about 1700°C and the melting point of the aluminum alloy is about 600°C, and there is a large difference in the melting points between the two, so an alloy layer cannot be formed at the bonding interface between the two.
A problem arose in that it easily peeled off. For this reason, we attempted to create irregularities on the surface of the stainless steel plate by thermal spraying or sandblasting with metal or inorganic materials, and to mechanically increase the bonding strength of the stainless steel plate by using the irregularities. However, since stainless steel plates have poor thermal conductivity, it is necessary to use as much heat as possible to conduct the heat of the pace body to its surface. When force unevenness is applied, unevenness also occurs on the opposite side, resulting in a disadvantage that the smoothness is impaired.

にある。This invention was made by focusing on the points mentioned above.
The purpose of this is to first press-fit an auxiliary metal plate having a melting point close to that of the metal for paste molding onto a stainless steel plate, then incorporate this stainless steel plate into a mold for paste molding, and place the metal plate for paste molding in the mold. An object of the present invention is to provide a method for manufacturing a heat dissipation paste that enables a thin stainless steel plate to be reliably and firmly bonded to the paste via the auxiliary metal plate by casting metal and bonding it to the auxiliary metal plate. .

。The auxiliary metal plate 3 is made of a metal having a melting point close to that of the metal constituting the pace main body 1, that is, the melting point of an aluminum alloy (approximately 600° C.), such as an At-81-Mg alloy. However, as shown in FIG. 3, the stainless steel plate 2 of the lever is
It is assembled into a mold 4 for pace molding. This mold 4 consists of an upper mold 4a and a lower mold 4b which are joined so as to be able to come into contact with each other.
A pouring port 5 is formed at a. Next, aluminum alloy is cast into the mold 4 through the pouring port 5 to form the paste body 1. Incidentally, at this time, a heat generating body (not shown) such as a sheathed heater is placed in advance in the mold 4, and then it is buried in the pace body 1. The pace body 1 is joined to the auxiliary metal plate 3, and since the auxiliary metal plate 3 has a melting point close to the melting point of the pace body 1, a fourth layer is formed at the joint interface between the pace body 1 and the auxiliary metal plate 3. As shown in FIG. 6, an alloy layer 6 of both metals is formed. After the stainless steel plate 2 is integrally joined to the pace body 1 in this manner, the pace body 1 is taken out from the mold 4.

強固なものとなる。In this way, the stainless steel plate 2 is firmly connected to the pace main body 1 via the alloy layer 6, and therefore it is necessary to perform unevenness treatment on the stainless steel plate 2. Therefore, the stainless steel plate 2 is made extremely thin. This allows the heat of the pace body 1 to be well conducted to the surface of the stainless steel plate 20. Furthermore, if the auxiliary metal plate 3 is made relatively thick and its surface is textured, the bonding force between the pace main body 1 and the auxiliary metal plate 3 is further strengthened, and the bonding between the stainless steel plate 2 becomes even stronger. becomes.

良好に伝導させることができるという効果を奏する。Since the stainless steel plate can be made thinner, the bond can be firmly strengthened, and the stainless steel plate can be made thinner so that the heat of the paste main body can be conducted well to the surface of the stainless steel plate.
