CARBON BLACK-CONTAINING MASTER BATCH, THERMOPLASTIC RESIN COMPOSITION CONTAINING THE SAME, AND MOLDED PRODUCT OF THE SAME
Document Type and Number:
Japanese Patent JP2022160824
Kind Code:
A
Abstract:
To provide a carbon black-containing master batch which enables easy manufacture of a molded product which is excellent in black color development property, appearance characteristics with no spitting and weather resistance, a thermoplastic resin composition using the carbon black-containing master batch, and a molded product of the same.SOLUTION: A carbon black-containing master batch (B) contains 100 pts.mass of the total of 5-70 pts.mass of carbon black (b-1) having a number average particle diameter of 10-20 nm of primary particles, 10-93 pts.mass of a hard copolymer (b-2) containing an aromatic vinyl-based monomer unit and a vinyl cyanide-based monomer unit, and 2-20 pts.mass of a dispersant (b-3), wherein its particle size is 150-300 μm. A thermoplastic resin composition contains the carbon black-containing master batch (B) and a thermoplastic resin (A). A molded product is obtained by molding the thermoplastic resin composition.SELECTED DRAWING: None
