いる。The injection molding method is an excellent processing method in terms of increasing the efficiency of the production process because it allows products with complex shapes to be manufactured in a small number of steps. Also, the specific gravity of plastic is small.
, which has the advantage of being lightweight. Therefore, in recent years, there has been a rapid increase in the use of plastic materials, either as single plastics or as composite materials such as FRP, and in particular, the use of plastic for OA type equipment is rapidly progressing.

散接合性にも富む、という特徴がある。On the other hand, there is a phenomenon in which materials elongate abnormally under certain conditions and their deformation resistance is significantly reduced. This phenomenon is called "superplasticity," and Zn-22Al alloy is known as a material exhibiting this phenomenon. In the state where the Zn-22Al alloy exhibits the ultram phenomenon, it has the following characteristics: it has extremely large deformability, extremely excellent electromagnetic wave absorption ability, vibration absorption ability, and sound absorption performance, and excellent diffusion bonding properties. be.

が適している。In order to bring out the superplastic phenomenon, it is essential to refine the metal structure. In order to satisfy this condition, the cooling rate when molten metal solidifies must be increased, but this rate is much faster for powder, which has an extremely small volume, than for bulk material (molten material). . Therefore, in order to develop superplasticity, powder is generally more suitable as a starting material.

@Plastic powder is generally produced by an air atomization method or an argon gas atomization method. The present inventor first discovered that heating this superplastic powder at 38θ°C for 30 minutes and then immersing it in ice water to perform a rapid cooling treatment is extremely effective in promoting superplasticization. It is disclosed in Japanese Patent Publication No. 59-157201. In the present invention, when Zn-22Al superplastic powder subjected to this quenching treatment is used,
It is possible to improve the density and strength of the molded body, which is even more effective.

耐えるだけのバルーンの強度が要求される。Regarding the blending ratio (wt%) of IIf plastic powder, ceramic balloon, magnetic powder, and plastic (powder),
As the number of ceramic balloons increases, the molded body becomes more porous, which improves sound absorption and reduces weight, but on the other hand, the molded body has poor ductility, strength, and moldability. Therefore, the blending ratio of ceramic balloons is 1 to 50% by weight.
, and more preferably 1 to 20% by weight. In the case of the present invention, the chemical composition of the ceramic balloon is not limited to a specific one; for example, a ceramic balloon can also be used. However, since the molding method is a pressure molding method using a mold, the strength of the shirasu balloon may cause it to break or shatter during molding. The balloon must be strong enough to withstand the molding pressure.

As the amount increases, the magnetic properties and electromagnetic wave absorption ability of the molded product improve, but the strength and moldability of the molded product deteriorate.

The remainder of the 22Al f plastic powder will be occupied by the ceramic balloon and the magnetic powder 5ζ ribs/or plastic7.Next, regarding the molding processing conditions, the main elements include loading temperature, IJ! 2. Among these factors, the force n [temperature and molding pressure are particularly important, that is, in the case of cold coloring, In comparison, in the case of hot forming,
It is possible to reduce the applied force. The heating temperature should be set at a temperature that will exhibit thermosetting properties when mixing Zotes-Zuri.
The appropriate temperature ranges from about 100°C to 250°C, which is the temperature at which Zn-22Al exhibits TFL plasticity.

都合である。Since the density cannot be higher than that, there is no need to increase the molding pressure excessively. When hot-opening molding is performed at 100 to 250°C, 1 to 30 kgf/sm2 is appropriate.
In the case of hot pressing, 1 to 20 kgf/mm2 is sufficient. In the case of cold open molding, 3 to 60 kgf/m
m2 is appropriate. As for the duration of the forming pressure, there is no problem even if the duration is instantaneous, such as in forging with a single mechanical press, but if the pressure is applied for a longer time using the hot press method, it is effective in improving the density of the compact. and
Therefore, it is possible to improve the strength of the molded body itself. However, when Zn-22Al superplastic material is
If left for more than about 0 minutes, the crystal grains will become coarser and the superplastic performance will deteriorate. Therefore, the upper limit of the pressure holding time when using the hot press method is 60 minutes. In the case of cold-open molding, if it is fired at 100 to 250°C, which is the thermosetting temperature of plastic after cold-open molding,
The strength of the molded body can be improved to some extent. It is also more convenient to use plastic powder suitable for cold forming.

Thermal open molding was carried out at a molding pressure of 20 kgf/mm2 and a molding temperature of 240°C. The obtained superplastic composite material (density: 4.2
The vibration damping capacity η of the 48g/c layer 3) is o,oos~0.0
It was 1.

下することがわかる。(Example 2) By varying the blending ratio of Zn-22Al superplastic alloy powder manufactured by air atomization method and balloons mainly composed of silica, and cold forming at a molding pressure of 42.5 kgf/mm2. The strength of the obtained superplastic composite material is determined by JI
It was measured using the disc compression test method of SA1113, and the results are shown in Figures 2A and B. Figure A shows the relationship between the strength and the mixing ratio of the ceramic balloon, and Figure B shows the relationship between the strength and the density of the superplastic composite material. From the results in Figure 2,
It can be seen that as the mixing ratio of ceramic balloons increases, the strength decreases considerably.
