本発明は、発泡ポリスチレンシートの上下面に夫々色の

The present invention relates to a method of manufacturing the invention which is particularly advantageous.

あり、設備的に不利な欠点がある。(Prior Art and Problems) Conventionally, the following methods have often been used for laminating foam sheets. (a) Foam sheets are bonded to the surfaces of the extruded foam sheets to be laminated using heat or adhesive. (2) Form an extruded foam sheet and bond the foam sheet to the same line with adhesive, or
Laminate while in a thermally softened state. However, (a)
is disadvantageous because it requires many steps. Although method (b) is more advantageous than method (a), it requires separate sheet dies, which is disadvantageous in terms of equipment.

方法を内容とする。(Means and effects for solving the problem) The present invention extrudes a foamed polystyrene sheet into a cylindrical shape from a circular die, forms a balloon, and presses this with pinch rolls to form a plate. In this method, foaming resins of different colors are extruded inside the upper half and lower half of the circumference of the foam sheet inside a circular die, thereby forming foams of different colors on both sides of the foam sheet. The content includes a forming method in which sheets are laminated at the same time.

時に成形することができる。中心の発泡層とと下の被覆
発泡層の密着性も優ｎている。In the method of the present invention, by using different extruders for the upper and lower semicircles, the color of the upper and lower semicircles can also be changed. As a result, the foam layer serving as the core material and the foam layer on the lower side can each change in color, allowing beautiful multi-colored boards to be molded at the same time. The adhesion between the central foam layer and the underlying foam layer is also excellent.
上記サーキュラダイスでなくＴダイ法では、発泡押出し
シートを中心としたものでは、発泡倍率の高い（１０倍
位）製品も、低倍率（５倍位）の製品にも、同一金型で
はできない。When using the T-die method instead of the circular die described above, it is not possible to produce products with a high foaming ratio (about 10 times) or products with a low foaming ratio (about 5 times) using the same mold, especially for foamed extruded sheets.
本発明では、中心発泡層及びそのと下の発泡層毎に互に
異なる色に着色Ｔることができ、またと下の発泡層が比
較的肉厚のときは発泡層であるから立体感を出すことが
可能であり、また保温・保冷効果も向とするなど優ｎｒ
こ効果も奏する。In the present invention, the central foam layer and the foam layers below it can be colored in different colors, and when the foam layer below is relatively thick, it is a foam layer, so it creates a three-dimensional effect. It has excellent properties such as being able to release heat and retaining heat and cold.
This effect is also produced.
上記説明した通りであり、本発明はサーキュラダイで発

出すことができる。As explained above, when foaming and extruding with a circular die, the present invention uses the same die to make the foamable resin into an upper half circle, and the upper half circle becomes a core material inside the die by using extruders on each side. Since it is extruded while being coated on the foamed resin, the colors of the upper and lower parts can be changed arbitrarily and the foamed resin can be extruded simultaneously with the central foamed layer.
従って、多色の美麗なシートを設備的にも有利に工業的
に生産することができるものである。Therefore, beautiful multicolored sheets can be industrially produced with advantage in terms of equipment.
