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 composition for producing a non-halogen flame retardant insulating material having a cut-through property and a method for producing a non-halogen flame-retardant insulating material having a cut-through property using the same. The composition for producing a non-halogen flame-retardant insulating material having a cut-through property according to the present invention, 100 parts by weight of a polyolefin resin that is a base resin; 110 to 300 parts by weight of a metal hydroxide of an inorganic flame retardant; 5 to 100 parts by weight of zinc borate which is a flame retardant aid; 0.5 to 20 parts by weight of fatty acid processing aid; 0.5 to 20 parts by weight of tartaric acid processing aid; And 0.5 to 5 parts by weight of antioxidant; characterized in that consisting of. According to the present invention, since the halogen element is not included in the composition composition used, it can be said to be more environmentally friendly than conventional halogen-based products during combustion, and it is possible to secure the flame retardancy required by the high flame retardant grade VW-1. In addition, it is possible to meet the cut-through characteristics to improve the productability, and in the case of using as an insulating material, in particular, an insulating coating layer for electric wire, it is preferable because the physical properties such as the required tensile strength and elongation can be secured well.;Cut-through, flame retardant, zinc borate, metal hydroxide, crosslinking
