として使用されている。この積層体は、第２図に示すよ
うにウレタンフオームシートＩＫ熱硬化性樹脂からなる
接着剤２を介してポリエステル系樹脂からなる表皮材３
を接着、積層した後、高周波加工して成形している。The laminate of this building can be used as a vehicle interior material such as a door) or as a cushion covering material A as shown in Figure 1.
is used as. As shown in FIG. 2, this laminate is bonded to a skin material 3 made of a polyester resin via an adhesive 2 made of a urethane foam sheet IK thermosetting resin.
After being bonded and laminated, they are molded using high-frequency processing.
しかしウレタンフオーム７−ト１を構成するポリウレタ
ン樹脂１表皮材３を構成するポリエステル系樹脂及び接
着剤２を構成する熱硬化性樹脂は、いづれもウェルダー
性能が弱い。すなわち、高周波加工は、樹脂に高周波を
かけて、加熱溶融せしめ、これによシ各樹脂を接合する
ものであるが、上述した樹脂は、高周波をかけても溶融
し難い。このためウレタンフオームシート１と表皮材３
とが剥れやすい問題がある。However, the polyurethane resin 1 constituting the urethane foam 7-1, the polyester resin constituting the skin material 3, and the thermosetting resin constituting the adhesive 2 all have poor welding performance. That is, in high frequency processing, resins are heated and melted by applying high frequency waves, and thereby the various resins are bonded together. However, the above-mentioned resins are difficult to melt even when high frequencies are applied to them. For this reason, the urethane foam sheet 1 and the skin material 3
There is a problem that the edges tend to peel off easily.
本発明は、この問題を解消すべくなされたもので接着剤
にウェルダー性能の有する助剤を含ませることによシ、
高周波加工を良好におこなうことができる積層体の製造
方法を得んとするものである。The present invention has been made to solve this problem by incorporating an auxiliary agent with welding performance into the adhesive.
The object of the present invention is to provide a method for manufacturing a laminate that can be satisfactorily subjected to high-frequency processing.

周波加工して成形することを特徴とする。That is, in the present invention, between the urethane foam sheet and the skin material, 20 to 30% of an auxiliary agent having welding performance, such as powder or emulsion of nylon or vinyl chloride resin, is added.
It is characterized in that it is bonded with an adhesive containing 0% by weight, and is formed by high-frequency processing.
以下本発明を第３図を参照して説明する。The present invention will be explained below with reference to FIG.
まず、ウレタンフオームシートｌと表皮材３との間に接
着剤４を塗布等によシ介在せしめて重ね合せる。ウレタ
ンフオームシート１は、ポリウレタン樹脂を発泡成形し
たもので、その厚さは用途によって異なるが通常２〜１
５−程度である。−万人皮材３は、ｓ”）エステル系樹
脂織布、不織布等、ウェルダー性能を持たない樹脂から
なシ、その厚さは通常０．５〜３燗程度である。接着剤
４は、熱硬化性樹脂からなり、ここにウェルダー性能を
有する助剤を含有している。この助剤は、例えばナイロ
ン又は塩化ビニル樹脂の粉末又はエマルジョンなどから
なる。First, an adhesive 4 is applied between the urethane foam sheet 1 and the skin material 3 by coating or the like, and the sheets are overlapped. The urethane foam sheet 1 is made by foam-molding polyurethane resin, and its thickness varies depending on the application, but is usually 2 to 1.
It is about 5-. - The universal skin material 3 is made of a resin that does not have welding properties, such as s'') ester resin woven fabric or non-woven fabric, and its thickness is usually about 0.5 to 3 mm.The adhesive 4 is It is made of a thermosetting resin and contains an auxiliary agent having welding properties.This auxiliary agent is made of, for example, nylon or vinyl chloride resin powder or emulsion.
この助剤の含有量は、高周波加工時のウェルダー性を考
慮して３０〜１５０重量％が好適であこのようにウレタ
ンフオームシート１と表皮材３とを接着剤２で接着した
後、ロール状電極Ｂを用いて第４図に示すように高周数
加工を行なう。この高周波加工は、常法に従ったもので
、約４０〜７０ ＭＨｚの高周波を発生させて誘電加熱
によシ助剤を軟化溶融させ、もってウレタンフオームシ
ート１と表皮材３とをライン状・格子状等に溶接する。The content of this auxiliary agent is preferably 30 to 150% by weight in consideration of weldability during high-frequency processing. After bonding the urethane foam sheet 1 and the skin material 3 with the adhesive 2 in this way, the urethane foam sheet 1 is formed into a roll. Using electrode B, high frequency machining is performed as shown in FIG. This high frequency processing follows a conventional method, in which high frequency waves of approximately 40 to 70 MHz are generated to soften and melt the auxiliary agent through dielectric heating, thereby forming the urethane foam sheet 1 and the skin material 3 into a line shape. Weld in a grid pattern, etc.
