Abstract

The invention relates to the technical field of spinning oil agents, in particular to a PAN-based carbon fiber precursor oil agent and a preparation method thereof. The PAN-based carbon fiber precursor oiling agent is prepared from the following components in percentage by mass of 5%-50% of amino and epoxy group modified organic silicon emulsion, 5%-35% of polyether modified organic silicon emulsion, 0.5%-10% of quaternary ammonium salt, 0.1%-5% of a wetting agent and deionized water. During preparation, the amino and epoxy group modified organic silicon emulsion and the polyether modified organic silicon emulsion are added into a variable-speed mixer according to the proportion and stirred uniformly, then the quaternary ammonium salt is added according to the proportion and stirred, finally the wetting agent and the deionized water are slowly added according to the proportion, and the materials are stirred uniformly and sub-packaged. The PAN-based carbon fiber precursor oiling agent is good in quality stability and heat resistance, adhesion and doubling of PAN precursors in the pre-oxidation process can be effectively prevented, pore defects in the high-temperature carbonization process are reduced, and the amount of broken filaments is reduced.

Description

Technical field[0001]The present invention belongs to the technical field of carbon fiber auxiliaries, and in particular, a PAN-based carbon fiber primer and a preparation method thereof thereof in the fiber process are used to exhibit anti-stick and isolation.Background technique[0002]Carbon fibers are a high-strength high modulus fiber composed of carbon elements, firing via a high temperature above 1000 ° C, including 90% carbon content, with light mass, high strength, high temperature, low creep, corrosion resistance Waiting for a series of advantages. The relative density of carbon fibers is only quarter of steel, but the tensile strength is four times that of high-performance steel, since there is a unique structure and mechanical properties, carbon fibers are widely used in aviation, aerospace, sports and leisure entertainment.[0003]The main raw materials of carbon fibers have viscose fibers, polyacrylonitrile (PAN) fibers, asphalt, phenolic, and the like. Since the productio...
