The invention relates to a method for preparing a raw material for asphalt resin by using kerosene co-liquefaction product heavy oil. The method comprises the steps of firstly separating a polar component in a the heavy oil with a first extracting agent to obtain a poor polarity component oil; separating a non-aromatic component in the poor polarity component oil with a second extracting agent toobtain an aromatic-rich mixture, and recycling the second extracting agent in the obtained mixture to obtain a remaining material aromatic-rich component oil, namely, the raw material for preparing the asphalt resin. According to the method provided by the invention, the aromatic component with higher purity is obtained by removing the polar component and chain hydrocarbon component in the kerosene co-liquefaction product oil. The separation method provided by the invention is simple to operate and high in separation efficiency; furthermore, the needed extracting agents are wide in source, better in heat stability and low in price and toxicity, so that the method is suitable for large-scale application.
