摘要： PROBLEM TO BE SOLVED: To provide, regarding a method of making a film by heating and melting a brittle resin and extruding it from a T die into a non-oriented film, a manufacturing method of a brittle resin film which hardly causes cracks in the handling during and after the manufacture, and to provide a brittle resin film hard to develop cracks.
SOLUTION: A brittle resin A and a tough resin B are each heated and molten with a separate extruder and supplied to a molten resin supplying pipe connected to each extruder. To a feed block, which is formed by making openings in both sides of the lower part of the pipe which supplies the brittle resin A and connecting the end of the tough resin B supplying pipe to the openings provided for these both sides, there are supplied the heated and molten brittle resin A and tough resin B. Subsequently the resins are widened by a manifold installed in succession to the feed block and extruded from the die lip of an extruding T die onto a casting roll in such a state that both sides of the brittle resin A are flanked by the tough resin B. Thus produced is the non-oriented brittle resin film whose center consists of the brittle resin and whose both sides have the tough resin portions.

摘要翻译：要解决的问题：为了提供一种通过加热熔融脆性树脂并将其从T模头挤出成非取向膜来制造薄膜的方法，所述脆性树脂薄膜的制造方法难以引起在制造期间和之后的处理中的裂纹，并且提供难以发展裂纹的脆性树脂膜。解决方案：将脆性树脂A和韧性树脂B各自加热并用单独的挤出机熔融并供给到连接到每个挤出机的熔融树脂供给管。通过在管的下部的两侧形成开口并供给脆性树脂A并将韧性树脂B供给管的端部连接到为这两侧设置的开口而形成的供给块，加热和熔化的脆性树脂A和韧性树脂B.随后，通过安装在进料块上的歧管将树脂加宽并从挤出T模头的模唇挤出到铸辊上，脆性树脂A侧面是韧性树脂B.因此，制造的是中心由脆性树脂构成的两面具有坚韧的树脂部分的非取向的脆性树脂膜。版权所有（C）2007，JPO＆INPIT
