Abstract

The invention discloses a polycarbonate resin-based suspension sizing agent for carbon fibers and a preparation method thereof. The suspension sizing agent of the present invention is composed of polycarbonate resin, dispersant, stabilizer and deionized water. The preparation method of the present invention is simple, and the obtained suspension sizing agent has good stability. The sizing carbon fiber prepared by using the sizing agent of the present invention is suitable for intermediates such as carbon fiber fabrics and prepregs for polycarbonate resin-based composite materials, and has good processing performance. and interface capabilities.

Description

technical field [0001] The invention belongs to the field of carbon fiber sizing agents, in particular to a polycarbonate resin-based suspension type sizing agent for carbon fibers and a preparation method thereof. Background technique [0002] Thermoplastic polycarbonate resin has been widely used in civil and industrial fields such as glass, electronics, and automobiles because of its excellent transparency, impact toughness, and dimensional stability. As the industrial field continues to put forward new requirements for polycarbonate resin applications and fields, the application of polycarbonate resin composite materials has gradually expanded, especially carbon fiber reinforced polycarbonate resin composite materials prepared with carbon fiber as a reinforcing phase, combined with Carbon fiber is lightweight and high-strength and polycarbonate resin is transparent and high-tough. The appearance and performance of the prepared products have typical characteristics, which...
