The invention belongs to the technical field of preparation of warm mixing agents from waste rubber and plastic cracking products, and provides a method and equipment for preparing a warm mixing agent from waste rubber and plastic cracking products. The warm mixing agent is prepared by the following steps: firstly, heating the solvent to 90-120 DEG C; adding the waste plastic cracking wax and the asphalt resin into the solvent, and uniformly stirring and mixing; adding a catalyst into the mixture, heating to 160-180 DEG C, and stirring to obtain a dispersed suspended matter; and finally, cooling the temperature of the mixture to 70-90 DEG C, adding a cross-linking agent, adding the obtained mixture into grinding equipment, performing three-stage grinding on the mixture, keeping the temperature after grinding, continuously stirring, and then cooling to room temperature to obtain the warm mixing agent. The warm mixing agent provided by the invention can reduce the construction temperature and the surface tensio
