Embodiment 1

[0198] Prepare the resin composition:

[0199] Using a twin-screw extruder (manufactured by Nippon Steel Works Co., Ltd. "TEX30a"), the cylinder temperature is 280°C, the mold temperature is 260°C, the pressure is 0.7bar (vacuum), the screw diameter is 30mm, and the rotation speed is 400rpm. Under the condition of an amount of 15 kg / hour, the mixture compounded according to the compounding amount (parts by weight) shown in Table 1 was melt-kneaded, and then melt-extruded. The resin composition obtained by melt extrusion was cooled by water cooling, cut into pellets using a pelletizer, and then dried at about 120° C. for about 5 hours to obtain a pellet-shaped resin composition.

[0200] Preparation of moldings:

[0201] Using a single-screw extruder (“GT50” manufactured by the Plastics Engineering Research Institute), the pelletized resin composition was melted under conditions of a cylinder temperature of 270°C, a mold temperature of 290°C, and an extrusion rate of 20 kg / hou...

Embodiment 2～15 and comparative example 1～4

[0203] A resin composition and a molded article were obtained in the same manner as in Example 1, except that the proportions (parts by weight) of the respective components were changed as shown in Tables 1 to 4 below.

[0204] (evaluate)

[0205] (1) Moldability

[0206] The obtained resin piece was cut into the size of 300 mm long x 300 mm wide x 3 mm thick, and the test piece was obtained. In a state where the obtained test piece was heated to 190° C., a tensile test was performed in accordance with JIS K7161-2:2014, and the elongation at break of the test piece was evaluated thereby.

Abstract

Provided is a resin composition which has excellent shapability and gives molded objects excellent in terms of flame retardancy and impact resistance. The resin composition according to the present invention comprises an aromatic polycarbonate resin, a sulfone resin having the structure represented by formula (1), an inorganic filler, a phosphorus-containing compound, and either a silicon-containing compound or silicon-containing particles.

Description

technical field [0001] The present invention relates to a resin composition containing an aromatic polycarbonate resin. Meanwhile, the present invention also relates to a molded article containing an aromatic polycarbonate resin. Background technique [0002] Thermoplastic resins such as polycarbonate resins are excellent in terms of durability, light weight, moldability, and the like. Therefore, thermoplastic resins are used in various fields such as the construction field, the home appliance field, and the transportation field. [0003] Specific uses of thermoplastic resins include interior materials for transportation machines such as railway vehicles, airplanes, ships, and automobiles. Examples of the above-mentioned interior materials include ceilings, window frames, handrails, backrests, table tops, and the like. [0004] In the above applications, molded articles using thermoplastic resins are required to have excellent flame retardancy and impact resistance. Howe...
