<p><P>PROBLEM TO BE SOLVED: To provide a flameproof protective sheet for obtaining high flameproofing and cost reduction, which protects a cable, a cable tube for storing the cable or the like from flames and a mechanical external force. <P>SOLUTION: A porous foaming body layer 2 is formed as a heat-resistant and heat-insulating layer directly on a metal sheet 1 without intervening an adhesive layer. The porous foaming body layer 2 is formed of a phosphoric acid and the like, a hardener for the phosphoric acid and the like, and an inorganic and organic composite foaming body including an urethane polymer having a NCO group, thus providing the heat-resistant and heat-insulating layer having high heat resistance, heat insulation and flexibility. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
