Problems solved by technology

[0005] However, the resin compositions described in Patent Documents 1 to 4 may be peeled off due to the vicinity of the high-shear gate shape and molding conditions.
In addition, especially when inorganic fillers, coloring materials, etc. are blended in the resin composition, the molded product may have uneven gloss, and further improvement is being sought.

Abstract

A polycarbonate resin composition which contains: 100 parts by mass of a resin component that is composed of (A) 60-95% by mass of an aromatic polycarbonate resin, (B) 2-30% by mass of a polyolefin resin and / or a polyolefin elastomer, each of which contains an epoxy group or a glycidyl group and (C) 1-38% by mass of a polyolefin resin other than the component (B); and (D) a phosphorus-containing compound. In this polycarbonate resin composition, the component (D) is composed of component (D1) and / or component (D2) described below. (D1) 0.01-0.5 part by mass of at least one compound that is selected from the group consisting of phosphite compounds and phosphate compounds, wherein at least one alkoxy group is bonded to a phosphorus atom (provided that in cases where the compound has an aryloxy group bonded to a phosphorus atom, hydrogen atoms are at all the ortho positions of the aryloxy group) (D2) 0.001-0.1 part by mass of at least one acid that is selected from the group consisting of phosphoric acid, phosphorous acid, phosphonic acid and phosphonous acid

Description

technical field [0001] The present invention relates to a polycarbonate resin composition and its molded body. More specifically, it relates to a molded article having excellent impact resistance, no delamination and less uneven gloss, and a polycarbonate resin composition providing the molded article. Background technique [0002] Polycarbonate resin is used as an important raw material for electronic, information, electric parts, mechanical parts, etc. due to its excellent mechanical strength such as heat resistance and impact resistance, and transparency. However, since it also has disadvantages such as low fluidity and poor chemical resistance, alloying of polycarbonate with polyolefin is being studied in order to improve these characteristics. [0003] For example, polycarbonate is alloyed with polyolefin-based resin and / or polyolefin-based elastomer having polycarbonate, an epoxy group, etc. (Patent Documents 1 to 4). Thereby, a polycarbonate resin having excellent f...
