Title: Electric wire insulated with foaming plastic and manufacture of the same
Inventor: OTSUKI HIDEO
IPC: H01B13/14
Filed: 1991-06-25
Abstract: PURPOSE:To increase the mechanical strength of a foaming body at the time of high rate foaming by mixing a decompose type foaming agent with a foaming aid agent which lowers the decomposition temperature of foaming agent in a hopper of an extruding machine, and keeping the processes from decomposition to extrusion at a comparatively low temp. CONSTITUTION:A foaming agent is mixed with a thermoplastic resin as ethylene-alpha olefin copolymer and polyethylene having a melting point below 135 deg.C, wherein the foaming agent has a main decompose temp. at least 50 deg.C higher than the melting point of the thermoplastic resin - this is called Material A. A foaming aid agent, which reacts with the foaming agent and lowers its main decompose temp. under the melting point of Material A. is mixed with thermoplastic resin - this is called Material B. Material A, B are mixed in a hopper. cast into an extruding machine, and extruded onto a conductor with the mixing/kneading temp. held below 150 deg.C to form a covering on the conductor. Therein any polyethylene having a melting point below 135 deg.C may be used whether its density is low, middle, or high. This enables high rate foaming, eliminates risk of destroying the bubbled wall, and enhances the mechanical strength remarkably.
