Embodiment 1-3

[0061] The ingredients shown in Table 1 were mixed, and the mixture was extruded into pellets using a conventional twin-screw extruder at 200-280°C. The resin pellets were dried at 80°C for 3 hours, and molded into test samples using a 6-ounce injection molding machine at molding temperatures of 180 to 280°C and 40 to 80°C for measuring flame retardancy. Flame retardancy was measured according to UL94VB at 1 / 10" thickness. Notched Izod impact strength was measured according to ASTM 256A at 1 / 8" thickness. Heat resistance was measured according to ASTM D 1525 at 5 kgf. Spiral length, the length of resin flow, was measured with a 10 oz injection molding machine at 250°C and at a molding temperature of 50°C with an injection flowmeter at a molding speed of 60%. Gloss was measured with a gloss meter at a measuring angle of 60°.

Abstract

Disclosed herein is a styrenic resin composition comprising (A) 15 to 80 parts by weight of a styrene resin, (B) 15 to 80 parts by weight of a polyphenylene ether resin, and (C) 0.1 to 25 parts by weight of a phosphoric compound comprising (c ) 1 to 30 % by weight of an alkyl phophinic metal salt and (c ) 70 to 99 % by weight of an aromatic phosphoric acid ester, per 100 parts by weight of a base resin comprising (A) and (B).

Description

technical field [0001] The invention relates to a flame retardant styrene composition. More particularly, the present invention relates to a flame retardant styrene composition having good flame retardancy and mechanical strength by using a phosphorus compound containing a metal phosphinic acid compound and an aromatic phosphate compound. Background technique [0002] A well-known method for flame retardancy of resins is to add halogen-containing compounds and antimony-containing compounds to rubber-modified styrene-containing resins to impart good flame retardancy. Examples of halogen-containing compounds used in the above method are, for example, polybrominated diphenyl ether, tetrabromobisphenol A, bromine-substituted epoxy compounds, polyvinyl chloride, and the like. Antimony trioxide or antimony pentoxide is usually used as the antimony-containing compound. [0003] The method of improving flame retardancy by using halogen-containing and antimony-containing compounds ...
