Abstract

The invention relates to a method for preparing organic small molecule hybrid damping material. the current methods for preparing organic small molecule hybrid damping material have high production cost, and obtain the damping material with poor damping performance and mechanical properties. The raw material in the invention comprises: inorganic filling material, filling material surface treatment agent, organic small molecule auxiliary agent and polymer with polarity side group. The invention is characterized in comprising the following processes: high speed mixing by mixing machine; low speed mixing by mixing machine; extruding by conical double screws extruder; and forming by clothes hanger type dies with width of 1.2 meters; and quenching by three-rollers calendar. The invention has a low production cost and simple preparation process, and can be used in large-scale high efficient continuous production; and the prepared damping material has high vibration absorption efficiency and excellent mechanical properties.
