PROBLEM TO BE SOLVED: To provide a polypropylene resin molding material that can achieve both flame retardancy and weather discoloration resistance.SOLUTION: A polypropylene resin molding material contains a polypropylene resin, a bromine-based flame retardant, antimony trioxide, a phosphite antioxidant, a hindered phenol antioxidant, and octadecyl phosphate. The bromine-based flame retardant is 5-15 pts.mass, the antimony trioxide is 1-5 pts.mass, the phosphite antioxidant is 0.05-0.5 pt.mass, and the hindered phenol antioxidant is 0.05-0.5 pt.mass with respect to 100 pts.mass of the polypropylene resin.SELECTED DRAWING: None |
