なわれていた。Generally, polyurethane foam is manufactured using a mixing head as shown in FIG. Conventionally, the foam is colored by connecting a pipe for introducing a predetermined colorant to a hydroxyl compound introducing pipe connected to the raw material inlet 1 of the mixing head, and synchronizing the colorant when the hydroxyl compound is fed to the mixing head. Was carried out, and they were mixed, stirred and discharged.
ところが、このようにして得られる従来のポリウレタン
フォームにあっては、白一色、赤一色というように、す
べて単色で形成されていたため、質感が単調で、趣向の
変化に乏しい不満があった。However, in the conventional polyurethane foam obtained in this way, since it was formed of a single color such as a single color of white and a single color of red, the texture was monotonous and there was little dissatisfaction with the change in taste.
「問題点を解決するための手段」 本発明にあっては、複数の色調のフォームが混在して模
様を形成する多色模様のポリウレタンフォームを提供す
ることによって上記問題点の解決を図った。"Means for Solving Problems" In the present invention, the above problems were solved by providing a polyurethane foam having a multicolor pattern in which foams having a plurality of color tones are mixed to form a pattern.
以下、本発明の多色模様ポリウレタンフォームを詳しく
説明する。Hereinafter, the multicolored polyurethane foam of the present invention will be described in detail.
第１図は、本発明のポリウレタンフォームの１例を示す
もので、Ａ色部分２にＢ色部分３…が配されたスラブ品

第２図に示すように、大理石状あるいはしま状の模様が
表れる。FIG. 1 shows an example of the polyurethane foam of the present invention, which is a slab product in which an A-color portion 2 and a B-color portion 3 are arranged. If you cut this slab along the line II-II,
As shown in FIG. 2, a marble-like or striped pattern appears.
つぎに本発明のポリウレタンフォームを製造する方法を
説明する。Next, a method for producing the polyurethane foam of the present invention will be described.
まず第一の製造方法は、ヒドロキシル化合物をミキシン

けられている。The first manufacturing method is a method in which a colorant is intermittently and instantaneously introduced into an introducing pipe for guiding a hydroxyl compound to a mixing head. When carrying out this method, it is desirable to use the mechanism shown in FIG. This mechanism
The colorant tank 4, the pump 5, and the hydroxyl compound introducing pipe 6 are sequentially connected by the pipe 7 and the pipe 8. The pipes 7 and 8 are connected by a bypass pipe 9. An opening / closing valve 10 is provided near the introduction pipe 6 of the pipe 8. An opening / closing valve 11 and a throttle valve 12 are sequentially provided on the bypass pipe 9 from the pipe 8 side.
この機構にあっては、ポンプ５が連続運転され、開閉バ

絞りバルブ12は、安定した着色剤の投入を行うために、
循環時の着色剤の圧力を吐出時の圧力よりも高く（吐出
時圧力＋0.2〜5.0kg/cm2）維持するためのものである。
この機構で着色剤を注入して多色模様のポリウレタンフ
ォームを生産する際には、着色剤の注入時間を0.1〜5.0
秒、中断時間を0.1〜5.0秒程度に設定すると、品質の安
定したポリウレタンフォームを製造することができる。In this mechanism, the pump 5 is continuously operated and the opening / closing valves 10 and 11 are alternately opened and closed. When the valve 10 is opened, the colorant is introduced into the introduction pipe 6 in which the hydroxyl compound is flowing. When valve 10 is closed, valve 11
Is opened and the colorant is circulated through the bypass pipe 9.
The throttle valve 12 has a
This is for maintaining the colorant pressure during circulation higher than the pressure during discharge (discharge pressure + 0.2 to 5.0 kg / cm 2 ).
When a colorant is injected by this mechanism to produce a polyurethane foam with a multicolor pattern, the time for injecting the colorant is 0.1 to 5.0.
By setting the second and the interruption time to about 0.1 to 5.0 seconds, it is possible to manufacture a polyurethane foam with stable quality.
このように着色剤を投入する場合、着色剤の投入は、上
記ヒドロキシル化合物導入用配管６以外の場所で行うこ
ともできる。例えば、触媒を導入する配管、発泡機（混
