    • PURPOSE:To manufacture a door panel excellent in weatherproofness by a method wherein two molded bodies each of which is prepared by making monolithic a vinyl chloride film and a polyurethane foam body having the same pattern with a wood-carved door are superposed through the intermediary of a supporting base body. CONSTITUTION:A duplicate die 1 is prepared by using a wood-carved door as a master form. On the inner surface of this duplicate die 1, a vinyl chloride film 2 whereon the same pattern with the surface of the wood-carved door is printed is subjected to vacuum molding with the printed surface directed to the die 1 so that the undulation of the die 1 are matched with the pattern of the film 2. Next, a foamable polyurethane resin stock solution 3 is cast on the film 2 and, a supporting base body 4 being put thereon, it is foamed and set. Then, removal is made from the die, and a molded body A is obtained. Next, another film 2 is subjected to vacuum molding on the die 1 in the same way, another foamable polyurethane resin stock solution 3 is cast thereon, the molded substance A is mounted later thereon, the stock solution 3 is foamed and set, a monolithic body thus prepared is removed from the die, and thus a door panel 6 is obtained.
    • 目的:通过以下方法来制造耐候性优良的门板:通过将通过制造整体式氯乙烯膜和具有与木雕门相同图案的聚氨酯泡沫体制成的两个成型体通过中间体 支撑基体。 构成:通过使用木雕门作为主形式准备复制的模具1。 在该复制模具1的内表面上,印刷与木雕门的表面相同的图案的氯乙烯膜2,其中印刷表面被引导到模具1,使得其的起伏 模具1与膜2的图案相匹配。接下来,将泡沫聚氨酯树脂储备溶液3浇铸在膜2上,并且将支撑基体4放置在其上,将其发泡和固化。 然后,从模具中取出,得到成型体A. 接下来,以相同的方式在模具1上进行真空成型,在其上浇注另一种发泡性聚氨酯树脂储备液3,其后安装成型物质A,将原料溶液3发泡成型, 将如此制备的本体从模具中取出,得到门板6。
