CPVC FLAME RETARDANT COMPOSITION COMPRISING CHLORINATED POLYVINYL CHLORIDE

摘要

The present invention relates to a flame-retardant composition including chlorinated polyvinyl chlorides (CPVC), and more specifically, to a flame-retardant composition including CPVC to be used on an interior material such as a room door. The flame-retardant composition includes polyvinyl chlorides (PVC), CPVC, polyethylene wax, acrylic resins, chlorinated polyethylene (CPE), polyethylene oxides, stearic acids, and dibasic lead phosphites (DLP), and dioctyl phthalates (DOP). For 100 parts by weight of the polyvinyl chlorides, the flame-retardant composition includes: 10 to 20 parts by weight of the CPVC; 0.8 to 1.7 parts by weight of the polyethylene wax; 1.5 to 3.5 parts by weight of an acrylic resin; 1.0 to 2.3 parts by weight of the CPE; 0.2 to 1.2 parts by weight of polyethylene oxides; 0.2 to 1.2 parts by weight of the stearic acids; 0.2 to 1.2 parts by weight of the DLP; and 0.5 to 1.5 parts by weight of the DOP.
