し、これを取り出して形成するものである。 Conventionally, this type of ball has been disclosed in Japanese Utility Model Publication No. 16613/1983. This involves preparing several types of vinyl paste resin with different ball colors, injecting them simultaneously into two halves of a hollow spherical mold, sealing the hollow mold, and placing the mold at a temperature of 170-180°C. By rotating vertically and horizontally, the vinyl paste resin content is uniformly adhered to the inner wall of the mold by centrifugal force, forming a sphere of the same thickness, which is then cooled and removed from the mold.

の粘度を有するものを使用する。 Therefore, in order to eliminate such problems, the present invention was achieved as a result of various experiments and diligent efforts. That is, in the present invention, after a colored vinyl chloride paste for forming a ball body is placed in a rotary molding mold, a part of the colored vinyl chloride paste for forming a ball body is bonded to the upper part of the inner surface of the mold. A ball having a marble-like pattern is produced by adding a pattern-forming colored vinyl chloride paste and rotating it vertically and horizontally, and each of the colored vinyl chloride pastes has approximately the same viscosity. use.
以下、本発明の一実施例を図面に基づいて説明
する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.

塑剤60−120、顔料２−３、安定剤２−３である。 The drawing shows colored vinyl chloride paste for forming a ball body (hereinafter abbreviated as body paste) 1 and colored vinyl chloride paste for pattern formation (hereinafter abbreviated as pattern paste) 2, 2 in a rotary molding mold a.
If main paste 1 is white and pattern pastes 2 and 2 are black, add 30 parts of pattern paste 2 and 2 to 100 parts of main paste 1.
A ball rotomolded using this proportion will have a marble pattern with white prominently appearing on a black background. The main paste 1 and the pattern pastes 2 and 2 are pastes having the same viscosity,
The composition is 100 parts by weight of vinyl chloride, 60 to 120 parts of plasticizer, 2 to 3 parts of pigment, and 2 to 3 parts of stabilizer.

に係るボールが製造される。 Both pastes 1, 2, and 2 put into the rotary molding mold a by the method described above are heated (250°C, 5 minutes) while being subjected to horizontal and vertical rotational motion in the same way as in the conventional method. The main paste 1 and the pattern pastes 2 and 2 are mixed and gelled to a uniform thickness.
When this is cooled and taken out from the mold a, the ball according to the present invention is manufactured.
前記回転成形する際の加熱温度を230℃にしそ

のの如くの製品にならない。 In addition, according to the experiment, the main body paste 1 was inside the mold.
, and put pattern paste 2 so that it is laminated on the surface of main paste 1 and rotation molding.
The pattern paste 2 and the main paste 1 are not mixed and are clearly separated, so that no marble pattern is formed. Furthermore, when the main paste 1, the pattern paste 2, and the main paste 1 are laminated in this order, there is no distinction between the main paste 1 and the pattern paste 2, and the whole becomes a color similar to that of the pattern paste 2, and no marble pattern is formed. Furthermore, if the viscosity of the main paste 1 and the pattern paste 2 are changed and they are laminated into a mold, the color of the paste as a whole will be similar to that of the paste with a similar viscosity, and the product will not be the same as that produced by the method of the present invention.
