Abstract

The invention relates to a carbon fiber oiling agent with a non-silicon oiling agent and a silicon-containing oiling agent compounded for use and a preparation method of the carbon fiber oiling agent. The carbon fiber oiling agent is obtained by compounding the non-silicon oiling agent and the silicon-containing oiling agent. The non-silicon oiling agent is prepared from, by mass, 100 parts of high heat-resisting compound A, 1-5 parts of antioxygen and 20-30 parts of surface active agent. The silicon-containing oiling agent is prepared from, by mass, 100 parts of side chain aminopropyl modified silicon oil, 3-10 parts of matter B and 20-30 parts of surface active agent. The carbon fiber oiling agent solves the problem of insufficient heat resistance of an existing oiling agent in the high-performance carbon fiber preparation process, and the non-silicon oiling agent and the silicon-containing oiling agent are matched for use, the preparation need of high-performance carbon fibers under different technological conditions can be met, so that the quality of the carbon fibers is improved.

Description

technical field [0001] The invention relates to an oil agent and a preparation method thereof, in particular to a carbon fiber oil agent compounded with a non-silicon oil agent / silicon-containing oil agent and a preparation method thereof, and belongs to the technical field of oil agents. Background technique [0002] Polyacrylonitrile-based carbon fiber (hereinafter referred to as carbon fiber) is an inorganic polymer fiber with a carbon content higher than 90%. It is the main reinforcing fiber for advanced composite materials. It has the characteristics of high strength, low density, no creep, and corrosion resistance. Widely used in aerospace, national defense, automobile, wind power, construction and other industries. The main preparation process of carbon fiber includes steps such as spinning, coagulation, drawing, oiling, steam drawing, setting, winding, pre-oxidation, low-temperature carbonization, high-temperature carbonization, etc. The oil agent is used in the oili...
