The present invention relates to the technical field of ultrasonic coupling pads, in particular to an ultrasonic coupling pad material and a preparation method thereof. The present invention adopts the following technical scheme: rubber or thermoplastic elastomer or soft plastic and mineral oil are used as main materials; specifically, the rubber or thermoplastic elastomer or soft plastic is first soaked in mineral oil for full absorption, and then extruded by a twin-screw extruder equipped with a liquid metering pump to obtain the coupling pad material. The beneficial effects of the present invention are as follows: it groundbreakingly breaks through the conventional coupling pad material using hydrogel as the base material, and adopts the combination of rubber or thermoplastic elastomer or soft plastic with mineral oil, so that the prepared coupling pad not only has good acoustic performance, but also has a wider range of application scenarios and reduced use cost.
