Abstract

The invention provides a resin composition, a production method of the same and a molded product, wherein the resin composition has excellent fluidity, impact strength of the molded product and flameretardancy when being melted. Provided is a resin composition containing a polycarbonate, a glass fiber, and an olefin-acrylate copolymer or an olefin-acrylic acid copolymer, wherein a mass ratio value (GFOA) of a content of the glass fiber (GF) to a content of the olefin-acrylate copolymer or the olefin-acrylic acid copolymer (OA) is in the range of 1.0 to 6.0.

Description

technical field [0001] The present invention relates to a resin composition, a method for producing the same, and a molded article. More specifically, the present invention relates to a resin composition excellent in fluidity during melting, impact strength of molded articles, and flame retardancy. Background technique [0002] Molded products are made thinner for the purpose of reducing the weight of molded products used in home appliances, automobiles, OA equipment, etc., and reducing the environmental load by reducing the amount of materials used. When the molded product becomes thinner, a decrease in rigidity becomes a problem, and it is effective to add a fibrous filler to increase the rigidity. On the other hand, if the above-mentioned fibrous filler is added, the fluidity at the time of melting is lowered, and the impact strength of the molded product is lowered, which becomes a problem. In addition, when a molded article becomes thinner, a decrease in flame retarda...
