Composition and method for production flame retardant insulating material of halogen free type with high voltage cut-through test

摘要

The present invention relates to a flame-retardant non-halogen-based flame-retardant insulating material manufacturing method having non-halogen-based composition for preparing an insulating material having a through-characteristic and the naekeot naekeot-through properties using the same. Halogen-based flame-retardant insulating material composition for preparing a non-naekeot having a through-characteristic according to the invention, based resin 100 parts by weight of the polyolefin base resin; with respect to the inorganic flame retardant is a metal hydroxide from 110 to 300 parts by weight; 5 to 100 parts by weight of zinc borate retardant aid; Fatty acid 0.5 to 20 parts by weight of processing aid; Tin-based processing aid is 0.5 to 20 parts by weight; And an antioxidant of 0.5 to 5 parts by weight, including characterized in that the made. According to the present invention, not used in the component composition it does not contain a halogen element may be referred to as eco-friendly compared to the conventional halogen-based products during combustion, it is possible to ensure the flame resistance required by the suffering soft grade VW-1. Further, naekeot can meet through characteristic and improved product property, the insulating material is preferable in particular also be satisfactorily secure physical properties such as mechanical strength such as the tensile strength and the elongation required for the case of using as the insulating coating for electric wire. ; Naekeot through, flame retardant, zinc borate, a metal hydroxide, cross-linked
