The surface of the molded product has a metallic luster, and also has the property of reflecting light rays in a wide range of wavelengths, and the shopping bag and the light rays (ultraviolet ray) that have excellent heat shielding effects that utilize these properties are used. , And infrared rays), films and sheets are actively produced as agricultural films that utilize the property of reflecting infrared rays. At this time, in order to exhibit an excellent metallic luster, it is necessary to use aluminum powder having a particle size of about 1 to 100 μm and disperse it uniformly in the resin. However, aluminum powder is inferior in workability such as danger of dust explosion and difficulty in dispersion in thermoplastic resin when used alone when blended with thermoplastic resin. It is used in the state of so-called aluminum powder paste dispersed in a solvent (generally using a high boiling point solvent: for example, mineral terpene).

る。Therefore, in the manufacturing process of the metal powder-containing resin composition, it is necessary to remove the solvent contained in the paste during the kneading process, and the kneading with the carrier resin is performed by heating and kneading with a Banbury mixer or roll. At the same time, the solvent is removed at the same time. The aluminum powder-containing resin composition thus obtained is
Bubbles are easily generated when heat-molded by adding diluted resin,
Therefore, it is difficult to obtain a molded product having a beautiful surface.
This drawback is strongly manifested in the film or sheet molding, and as the amount of aluminum powder used increases, the tendency becomes stronger and the commercial value is significantly impaired, and it is difficult to solve it.

低下して好ましくない。The quicklime (CaO) used in the present invention is obtained by baking limestone, or by baking calcium hydroxide or calcium carbonate, and its shape makes the surface of the obtained molded article beautiful. Fine powder is preferred for finishing. High-concentration aluminum powder-containing resin composition of the present invention, aluminum powder 20 ~ 8 per 100 parts by weight of olefin resin.
If 0 part by weight is blended, and if less than 20 parts by weight, when used as a masterbatch at the time of dilution, the amount used becomes large and the commercial value is poor, which is not preferable. On the other hand, if it is more than 80 parts by weight, it is difficult to knead the aluminum powder in the carrier resin during the production of the masterbatch, and the mechanical properties of the resulting molded article are deteriorated, which is not preferable. The amount of olefin wax used is 5 to 5
Add 0 parts by weight. If the amount is less than 5 parts by weight, the aluminum powder is not sufficiently dispersed in the carrier resin and the product value as a masterbatch is poor, which is not preferable. If the amount is more than 50 parts by weight, it is not preferable when manufacturing molded articles (eg film, sheet). It is not preferable because the physical properties are deteriorated.

に使用されているオレフイン系樹脂であれば良い。The amount of quicklime used is 2 to 10 parts by weight. If it is less than 2 parts by weight, the effect of suppressing the foaming phenomenon is poor during the production of molded articles such as films and sheets.
If the amount is more than the amount by weight, the physical properties of the molded product such as a film or sheet are deteriorated during production, which is not preferable. The amount of quicklime used mainly depends on the amount of aluminum powder used. The high-concentration aluminum powder-containing resin composition of the present invention may be produced by a conventional method that has been conventionally used, and as an apparatus, for example, an extruder, roll, Banbury mixer or the like is used. The composition of the present invention may contain stabilizers, ultraviolet absorbers, antistatic agents, lubricants, etc. to the extent that the characteristics are not impaired. Further, when a film is produced using the product of the present invention, it is carried out by a calendering method, a T-die method, an inflation method or the like which is usually performed. At that time, the thermoplastic resin for diluting the composition of the present invention may be an olefin resin which is usually used for molding.
