IPC: C08K3/02
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To improve the flame retardancy and control the generation of smoke by adding an inorganic filler and a halogenated flame retardant or a phosphorus- containing flame retardant each in a specified amount to a polyolefin resin. SOLUTION: This resin molding is obtained by mixing 100 pts.wt. polyolefin resin comprising, e.g. polypropylene with 50-150 pts.wt. inorganic filler, and 5-50 pts.wt. halogenated flame retardant or phosphorus-containing flame retardant and molding the mixture. Examples of the inorganic filler used include metal hydroxides such as magnesium hydroxide, and metal carbonates such as calcium carbonate, among which a hydroxide is advantageously used from the viewpoints of heat absorption due to dehydration reaction and an effect of controlling combustion due to the release of the water of crystallization. Examples of the flame retardant used include halogenated flame retardants comprising brominated flame retardants such as a brominated epoxy compound, and chlorinated flame retardants such as a chlorinated polyethylene.  It is desirable to use a halogenated flame retardant with a metal hydroxide serving as a halogen acceptor. Examples of the phosphorus-containing flame retardant used include a mixture of red phosphorus and titanium oxide for preventing discoloration, and phosphate flame retardants comprising, e.g. triphenyl phosphate.
