Abstract
The present invention provides a method of producing a molded article, which can be perform the continuous processes and effectively impregnate a modifying material such as metal complexes in the thermoplastic resin for short period of time. The above object is achieved by providing the method of producing the thermoplastic resin molded article which includes impregnating the high-pressure fluid having a modifying material dissolved therein, in thermoplastic resin, and continuously molding the thermoplastic resin in which the modifying material has been impregnated, into the form of a film.
Claims26
A method of producing a molded article, comprising:
- impregnating a high-pressure fluid containing a modifying material, in a thermoplastic resin;
- and
- continuously molding the thermoplastic resin in which the modifying material has been impregnated, into a form of a film.
A method of producing a molded article, comprising:
- melting a thermoplastic resin;
- preparing a high-pressure fluid containing a modifying material;
- bringing the high-pressure fluid into contact with the thermoplastic resin which has been molten to impregnate the modifying material into the thermoplastic resin;
- and
- continuously molding the thermoplastic resin in which the modifying material has been impregnated, into a form of a film.
An extruder, comprising:
- a heating cylinder which melts a thermoplastic resin;
- an extruding die;
- and
- an injection apparatus which impregnates a high-pressure fluid containing a modifying material into the thermoplastic resin which has been molten.
A molded article, comprising:
- a molded article body which is formed of thermoplastic resin and is molded by extrusion molding;
- and
- a metallic conductive film provided on the molded article body,
- wherein metallic fine particles are impregnated in a surface on a side of the metallic conductive film of the molded article body.
A molded article, comprising:
- a molded article body made of thermoplastic resin;
- a metallic conductive film provided on the molded article body;
- and
- a thermoplastic resin film provided between the molded article body and the metallic conductive film,
- wherein metallic fine particles are impregnated in a surface on a side of the metallic conductive film of the thermoplastic resin film.
