Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDED PRODUCT MANUFACTURED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2021/085867
Kind Code:
A1
Abstract:
A thermoplastic resin composition according to the present invention comprises: about 100 parts by weight of a polycarbonate resin; about 1 to about 20 parts by weight of a polyester resin; about 30 to about 80 parts by weight of glass fibers; about 5 to about 33 parts by weight of mica; and about 5 to about 25 parts by weight of a phosphagen-based flame retardant. The glass fibers comprise at least one of: a circular cross-section glass fiber having a sectional diameter of about 5 to about 20 ㎛ and a pre-processing length of about 1 to about 15 mm; and a rectangular cross-section glass fiber having a cross-sectional aspect ratio of about 1.5 to about 1.0, a cross sectional minor diameter of about 2 to about 10 ㎛, and a pre-processing length of about 1 to about 15 mm. The mica has a cross-sectional aspect ratio of about 90 to about 300 and a mean particle size (D50) of about 200 to about 550 ㎛. The weight ratio of the glass fibers and the mica is about 1.5 : 1 to about 7 : 1. The thermoplastic resin composition is excellent in terms of dimensional stability, flame retardancy, impact resistance, and the like.
