FLAME-RETARDANT FOAM INSULATING MATERIAL BASED ON CHEMICALLY CROSS-LINKED POLYVINYL CHLORIDE AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a flame-retardant foam insulating material based on chemically cross-linked polyvinyl chloride and a method for producing same. The present invention comprises a polyvinyl chloride resin and a chlorinated polyethylene resin, which have excellent flame retardancy, and thus can be used as an insulating material for construction. By comprising the chlorinated polyethylene resin which is excellent for use in combination with the polyvinyl chloride resin, the present invention increases the degree of cross-linking and thus allows high-magnification foaming and thereby has improved insulating properties.
