この発明は、独立気泡性樹脂発泡シートに表面材を積層
する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for laminating a surface material on a closed-cell resin foam sheet.
樹脂シートの片面もしくは両面に表面材を積層する方法
として、両者をロール間に通して接着乃至熱融着するこ
とはよく知られている。As a method for laminating a surface material on one or both sides of a resin sheet, it is well known to pass the two surfaces between rolls and bond or heat-seal them.
ところで、樹脂シートに独立気泡性の樹脂シートを用い
るときには、ロールによる熱圧着による発泡シートの気
泡の変形、破壊が起こりやすく、その後発泡シー１−を
加熱成型しようとするとき、発泡シートが肉やせしてし
まう問題点があった。By the way, when a closed-cell resin sheet is used as the resin sheet, the bubbles in the foam sheet are likely to be deformed and destroyed due to thermocompression bonding with rolls, and when the foam sheet 1- is then heated and molded, the foam sheet becomes thin. There was a problem with it.
独立気泡性樹脂発泡シートは、軽量で断熱性に優れてい

トに表面材を積層して補強乃至外装することによって自
動車等の内装材に使用されることが多い。Closed-cell resin foam sheets are lightweight and have excellent heat insulation properties, so they are used for a variety of purposes. In addition, this sheet is often used as an interior material for automobiles and the like by laminating a surface material for reinforcement or exterior covering.

問題点の解消が望まれていた。In such applications, not only appearance and physical properties but also
Dimensional requirements such as uniform thickness are also strict, and the foam sheet must not lose its thickness during heat molding for commercialization. It has been desired to solve the above-mentioned problems in manufacturing sheets.

積層シートの製造方法である。This invention has been made in view of the above-mentioned points, and when passing the closed-cell resin foam sheets 1 to 1 and the surface material between rolls and laminating them, the closed-cell resin foam sheets are heated. Instead, the surface material is heated and guided between heating rolls, and the closed-cell resin foam sheet is rapidly heated by the heating roll to induce foaming force and laminated under pressure, and this laminated sheet is rolled after 3 m. This is a method for producing a laminated sheet, which is characterized by cooling in a cool room.
この発明方法を図面を参照して更に説明する。The method of this invention will be further explained with reference to the drawings.

強度が要求される用途に好ましい。1 is a closed-cell resin foam sheet 1, for example, a polyethylene foam sheet (hereinafter simply referred to as a foam sheet); As the surface abrasion 2, a synthetic resin sheet such as polypropylene 1~ or other material is used. As the surface material 2, it is preferable to use, for example, a thermoplastic resin impregnated with a mixed fiber of glass fiber and organic fiber for applications requiring heat resistance and mechanical strength.

れて加熱ロール４．４間に送られる。The foam sheet 1 and the surface +A2.2 are sent between the heating rolls 4.4, and are pressed and fused together, but the foam sheet 1 is not particularly heated before being sent between the heating rolls 4.4. However, the facing material 2.2 is heated by a %-tar 3.3 and sent between heating rolls 4.4.

積層されって引き取られる。The foamed sheet 1 is rapidly heated between the heating rolls 4.4, and the foaming power of the foamed sheet 3 is induced. The foamed sheet 1 and the surface material 2.2 are pressed together and fused and laminated between the heating rolls 4.4. In this way, they are stacked and taken off.

泡シートの独立気泡の変形、破壊が生ぜず、寸法精度に
優れた積層シートが得られる。In the method of this invention, the closed-cell resin foam sheet is rapidly heated between hot rolls to induce its foaming force, and then is pressed against the heated surface material, so that the closed-cell resin foam sheets are deformed. , a laminated sheet with excellent dimensional accuracy without breakage can be obtained.
