Abstract

The invention relates to a large-tow carbon fiber oiling agent. The large-tow carbon fiber oiling agent is prepared from the following components in parts by mass: 60 to 70 parts of a compound A, 5 to 15 parts of quaternary ammonium salt block silicone oil, 1 to 5 parts of a liquid antioxidant and 10 to 20 parts of a surfactant. By adopting the large-tow carbon fiber oiling agent provided by the invention, the problems in a current large-tow carbon fiber preparation process that an oiling agent is stuck in a roller and has poor heat resistance, the anti-static electricity property is not lasting, and the like are solved; unification of properties including high attachment, high anti-static electricity property, low roller sticking property, high heat resistance and the like is realized by the single oiling agent; the requirements of preparation of large-tow carbon fibers are met, and the quality of the carbon fibers is improved.

Description

technical field [0001] The invention relates to an oil agent, in particular to a large tow carbon fiber oil agent, and belongs to the technical field of oil agents. Background technique [0002] In recent years, with the development of the domestic carbon fiber industry, the application of carbon fiber is not limited to traditional aerospace, national defense and military industry, wind power generation, sporting goods and other fields, but is also widely used in carbon fiber composite core cables, rail transit, automobiles, etc. Lightweight, construction and other industries, the demand is also growing rapidly. A large number of civilian uses of carbon fiber have put forward new requirements for its production cost. Low cost has become an inevitable trend in the development of carbon fiber, and large-tow carbon fiber has attracted more and more attention from manufacturers because of its excellent performance in reducing production cost. [0003] Carbon fiber oil is an ind...
