を要旨とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for manufacturing a metallic-like plastisol hollow molded article, which involves placing a certain amount of colored or colorless transparent plastisol into a shell-like split mold of a desired design. After sealing, the split mold is rotated around its axis using a rotary molding machine to semi-gel the plastisol inside, and in this semi-gelled state, the split mold is split open to form a colorless mold with aluminum powder mixed in advance. Alternatively, after putting a certain amount of colored plastisol into the mold and sealing it, the split mold is rotated again in a rotary molding machine to completely gel the above two types of plastisol, and then after cooling, the completely gelled product is taken out from the mold. The main points are as follows.
従来、この種のメタリツク調のプラスチゾル成
形品は塩化ビニルコンパウンドにアルミニウム粉

を現出していたが、これには下記の如き諸欠陥が
あつた。 Conventionally, this type of metallic plastisol molded product has been produced by blending aluminum powder and a large amount of pigment into a vinyl chloride compound to create a metallic color tone, but this has had the following drawbacks.
１ 多量のアルミニウム粉末を配合する為、物性
が極端に悪化する。1. Since a large amount of aluminum powder is blended, the physical properties are extremely deteriorated.
２ 多量のアルミニウム粉末を入れる為、自由な
調色ができない。2. Because a large amount of aluminum powder is added, it is not possible to freely adjust the color.
３ 多量のアルミニウム粉末を入れる為、色調が
不鮮明で彩度が極端に落ちる。3. Because a large amount of aluminum powder is added, the color tone is unclear and the saturation is extremely low.
４ 多量の顔料を入れる為、コストアツプが大き
い。4. Cost increase is large because a large amount of pigment is added.
５ 多量のアルミニウム粉末と多量の顔料が相互
に影響力を与えてアルミニウム本来の輝度が極
端に悪くなる。5. A large amount of aluminum powder and a large amount of pigment influence each other, and the original brightness of aluminum becomes extremely poor.
６ アルミニウム粉末が表面から落下して手に付
着したり衣服に付着したりして他の物を汚す。6 Aluminum powder falls from surfaces and gets on hands or clothes, staining other objects.
７ 成形品の表面に彩色塗装をするにしてもアル
ミニウム粉末が邪魔をして接着力が十分に得ら
れない。7. Even if the surface of the molded product is painted in color, the aluminum powder will interfere and will not provide sufficient adhesion.
また上記の如き諸欠陥を改善する為に、一部の
メーカーでは成形品の表面に塩ビ系クリア塗料を
塗つているが、十分には効果が上がらない。逆に
外観上、汚なく商品価値が下がり満足するもので
はない。 In order to improve the above-mentioned defects, some manufacturers apply a PVC-based clear paint to the surface of the molded product, but this is not sufficiently effective. On the other hand, the appearance is unsatisfactory as the product value decreases due to lack of dirt.
本発明により得た完成品は上記の如き諸欠陥を
充分に補つたものであり、特に鮮明度、物性の改
善の効果は多大である。 The finished product obtained by the present invention sufficiently compensates for the above-mentioned defects, and in particular, the effects of improvement in sharpness and physical properties are significant.
次いで、本発明の一実施例を説明するに、 〔使用ゾル〕 (A) 色透明ゾル PVCペースト 100 D.O.P 50 ノルマルパラフイン ６ 赤色顔料 0.3 安定剤 1.0 (B) シルバージル PVCペースト 100 D.O.P 40 ノルマルパラフイン ６ アルミニウム粉末（粒径20μ〜40μ） ５ 安定剤 ３ 〔成形法〕 １ 割型１に（Ａ）ゾル２を一定量入れる。 Next, to explain one embodiment of the present invention, [Sol used] (A) Color transparent sol PVC paste 100 D.O.P 50 Normal paraffin 6 red pigment 0.3 Stabilizer 1.0 (B) Silver Jill PVC paste 100 D.O.P 40 Normal paraffin 6 Aluminum powder (particle size 20μ~40μ) 5 Stabilizer 3 [Forming method] 1. Pour a certain amount of (A) Sol 2 into mold 1.
２ ローテーシヨン成形機（図示せず）内で自公
転させて(A)ゾル２を半ゲル化する。2. The (A) sol 2 is turned into a semi-gel by rotating it in a rotation molding machine (not shown).
成形温度 250℃ 成形時間 30秒 ３ 割型１を割る。 Molding temperature 250℃ Molding time 30 seconds 3 Break mold 1.
４ (B)ゾル３を一定量入れる。4 (B) Add a certain amount of Sol 3.
５ 割型１を閉め、ローテーシヨン成形機内で自
公転させて(A)ゾル２および(B)ゾル３を一体化の
完全ゲル化させる。5. Close the split mold 1 and rotate it in a rotation molding machine to completely gel (A) sol 2 and (B) sol 3.
６ 水冷 25±10℃×５分 ７ 割型から抜き取り製品を得る。6 Water cooling 25±10℃×5 minutes 7. Cut out the product from the split mold.
尚、上記の実施例は(B)ゾルに遠心力を作用させ
るのでアルミニウム粉末の各粒子が所謂乱れの方
向で並んだ状態となり乱反射でメタリツク調の輝
度が高くなる。また(A)ゾルと(B)ゾルの両方を異な

ることができないような複合色の製品を得ること
ができる。 In the above embodiment, since a centrifugal force is applied to the sol (B), each particle of the aluminum powder is arranged in a so-called disordered direction, resulting in diffused reflection, which increases the metallic brightness. Furthermore, when both the (A) sol and the (B) sol are colored and transparent with different colors, it is possible to obtain a product with a complex color that cannot be obtained with commercially available pigments.
