No.-212459 is a nylon 6 matrix compounded with 82.5% iron powder, and has a ratio of i1'j3. The f33 is 17゛ζ. In addition, in Special Publication No. 11261/1986, zinc powder 7 was used on a nylon 6 substrate.
By blending 4%, a specific gravity of 3.0 was obtained. Furthermore, as a technology for making materials with higher specific gravity, Japanese Patent Application Laid-Open No. 61-200165
No. 6 is a nylon 6 matrix blended with 90% zinc powder and reinforcing fibers to create a composition with a specific gravity of 4°4.
No. 9858 has a nylon 6 matrix and contains 85% iron powder to obtain a composition with a specific gravity of 4.34.

った。All of these are intended for mechanical parts such as flywheels, and there are few examples of the mechanical strength of iiP materials, but according to additional tests by the inventors, the tensile strength is 3. The IZOT (door i!3!!) value was about 3 kg/sa', which was significantly lower than that of IAJ fat alone.

もたれて来た。However, in recent years, high-density plastic materials have been applied to many products other than conventional flywheels inside machines due to their good performance and workability. ! 1: I came leaning on it.
この例として往１度刃型の電気カミソリがある。An example of this is a single-blade electric razor.
高比重祠料を外装のフレームやボディーに使用すること

先ず、成形品の流動長が長く薄肉で且つ複雑形状となる
ため成形加工性の優れていることが要求される。これは
材料の流動性と共に、平滑な表面、ウェルドが目立ちに
くいことなどがあげられる。First, since the molded product has a long flow length, is thin, and has a complex shape, it is required to have excellent moldability. This is due to the fluidity of the material, the smooth surface, and the fact that welds are less noticeable.
更に製品使用時の落下等による破ｆｉに耐える商い面４
ｉ！ｉ撃強度が要求される。Furthermore, it is commercially resistant to damage caused by dropping the product during use.

。又、チタン酸カリウムは繊維径が２〜３μと細いため
成形品の外観は優れるが、ガラス繊維配合に比べ強度向
上の効果は劣り、且つ材料単価が著しく高くなる。When using nylon-based compositions for machine 1M parts such as flywheels, it has been possible to improve impact resistance by adding reinforcing materials such as glass fiber and potassium titanate, but For commercial purposes, blending glass fiber is not a preferable method because of the loss of surface smoothness and the difficulty of painting and plating. Further, since potassium titanate has a fine fiber diameter of 2 to 3 μm, the appearance of the molded product is excellent, but the strength improvement effect is inferior to that of glass fiber combinations, and the unit cost of the material is significantly higher.
以上のように、新しい市場の要求に対し従来技術による
高比重材料は満足でないため、その改良が強（要求され
ているところである。As mentioned above, since the high specific gravity materials of the prior art are not satisfactory to the new market requirements, there is a strong demand for improvements.

たものである。(c) Problems to be Solved by the Invention The present inventor discovered that high-density plastic (1 material) containing gold mud powder at a high concentration is mainly used due to its mechanical strength, appearance, and moldability limitations. We have improved the current situation where it is used as a single dose for interior mechanical components, and it has excellent mechanical strength without the need for reinforcing materials such as glass fiber, especially high impact resistance, and is easy to mold. This invention was developed as a result of research aimed at developing a high-density composite material that has an excellent appearance as a molded product, has a particularly good paint finish, and has the properties to withstand use as housing parts for home appliances, etc. It is completed.
