Abstract

The invention belongs to the technical field of spinning auxiliary for an asphalt-based carbon fiber precursor fiber, and particularly relates to a spinning finish for an asphalt carbon fiber, and the spinning finish is mainly used for solving the problems that the existing spinning finish for asphalt-based carbon fiber can be molten when used for spinning a large bundle of asphalt-based carbon fibers. According to the technical scheme, the spinning finish for asphalt carbon fiber is prepared by performing ultrasonic mixing on the following raw materials in percentage by weight for 0.5h-3h: 5%-45% of carbon powder, 3%-6% of silicone oil, 0.1%-3% of antistatic agent, 0-0.3% of cohesive agent, 0.02%-2% of wetting agent, 0-0.2% of fiber splitting agent and the balance of deionized water. The spinning finish has the following advantages that the melting phenomenon in a process of spinning a large bundle of asphalt-based carbon fibers cannot exist, the friction and wear of fiber surface and a roller during production can be prevented, and the spinning finish has good antistatic property and toughness effect.

Description

technical field [0001] The invention belongs to the technical field of auxiliary agents for spinning pitch-based carbon fiber precursor fibers, and in particular relates to an oil agent for spinning pitch carbon fibers. Background technique [0002] Oil agent is an important auxiliary agent for the production of high-performance raw silk and carbon fiber. The manufacture of carbon fiber (especially the manufacture of high-performance carbon fiber) has strict requirements on spinning oil agent: such as excellent high temperature resistance to ensure High-temperature pre-oxidation and early carbonization can not only bundle but also prevent the adhesion of the precursor; excellent antistatic performance, to endow the precursor with good bundle and processability, and ensure the smooth progress of the spinning and pre-oxidation process; excellent Excellent lubricity and anti-adhesive isolation, in order to prevent monofilament adhesion in the initial stage of spinning, pre-oxid...
