Embodiment 1-1

[0163] (A)-1 and (B)-1 were dry-blended at a mixing mass ratio of 60:40, and then mixed at 230° C. using a 40 mmφ small co-rotating twin-screw extruder manufactured by Mitsubishi Heavy Industries to prepare pellets. Using Toshiba Machinery's injection molding machine IS50E (screw diameter: 25 mm), the obtained pellets were injection-molded at a cylinder temperature of 230°C and a mold temperature of about 70°C. 135mm×width 13mm×thickness 1.0mm test piece; for Izod impact strength evaluation, injection molded into length 64.0mm×width 12.7mm×thickness 4mm test piece; for load deformation temperature evaluation, injection molded into length 120mm× A test piece with a width of 11 mm x a thickness of 3 mm. Using the obtained test pieces, evaluations of flame retardancy, Izod impact strength, and load deflection temperature were performed. The results are listed in Table 1.

Embodiment 1-2

[0165] Using an injection molding machine IS50E (screw diameter: 25 mm) manufactured by Toshiba Machinery, under the conditions of a barrel temperature of 230° C. and a mold temperature of about 70° C., the pellets obtained in Example 1-1 were injection molded into a length of 135 mm×width of 13 mm×thickness A test piece of 2.0 mm was used for evaluation of flame retardancy, and the flame retardancy of the obtained molded article was judged to be V-0.

Embodiment 1-3

[0167] Using an injection molding machine IS50E (screw diameter: 25 mm) manufactured by Toshiba Machinery, under the conditions of a barrel temperature of 230° C. and a mold temperature of about 70° C., the pellets obtained in Example 1-1 were injection molded into a length of 135 mm × width of 13 mm × thickness A test piece of 3.0 mm was used for evaluation of flame retardancy, and the flame retardancy of the obtained molded article was judged to be V-0.

Abstract

An object of the present invention is to provide a resin composition which is excellent in terms of all of fire retardancy, impact resistance and heat resistance. The present invention relates to a resin composition which includes: a polycarbonate resin (A) that contains structural units (a) derived from a dihydroxy compound having the portion represented by the following formula (1) as part of the structure thereof; and a flame retardant (B) that contains phosphorus and nitrogen, wherein a test specimen produced from the resin composition in accordance with JIS K7110 has an Izod impact strength of 5.0 kJ / m 2 or higher and a molded article obtained by molding the resin composition has a rating of V-0 in a UL94 vertical burning test. (Provided that the case where the portion represented by formula (1) is part of -CH 2 -O-H is excluded.)

Description

technical field [0001] The present invention relates to a resin composition having excellent flame retardancy, impact resistance, and heat resistance, and a film, a plate, and a molded article obtained by molding the resin composition. Background technique [0002] Aromatic polycarbonate resins are widely used in various applications such as automobiles and OA equipment fields as engineering plastics with excellent heat resistance, impact resistance, and transparency. On the other hand, aromatic polycarbonate resins are usually produced using raw materials derived from petroleum resources. Considering concerns about the depletion of petroleum resources in recent years, plastic molding using raw materials obtained from biomass resources such as plants is required. Taste. In addition, due to concerns about the increase in carbon dioxide emissions, climate change caused by global warming due to accumulation, etc., it is required to develop a carbon-neutral carbon dioxide that ...
