Patent ID: 8735486

Claim:
A method for producing an exterior body of an electric appliance, the method comprising steps of: kneading one or more resin components and one or more flame retardancy-imparting components to give a flame-retarded resin composition satisfying V0 according to the UL Specification, and molding the flame-retarded resin composition by an injection molding method or a compression molding method, wherein: polylactic acid or a lactic acid copolymer is contained at a ratio of 55 wt % or more of an entire resin component, at least one of the flame retardancy-imparting components to make the flame-retarded resin composition satisfy the V0 according to the UL Specification is a catalytic cracking catalyst and the catalytic cracking catalyst is a solid acid silica-magnesia catalyst, proportion of magnesium oxide in the silica-magnesia catalyst being from 10 wt % to 24.5 wt %, the catalytic cracking catalyst is activated by being heated, before the step of kneading, the at least one flame retardancy-imparting component is contained in an amount of 0.5 wt % to 40 wt % of the flame-retarded resin composition, and no metal hydroxide and no polyvinyl chloride are contained in the composition.
