Title:
NANO TIN CONDUCTIVE RUBBER COMPOSITE MATERIAL, SENSOR, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/083414
Kind Code:
A1
Abstract:
The present invention relates to the technical field of pressure measurement, and provides a nano TiN conductive rubber composite material, a sensor, and a preparation method therefor. The composite material provided in the present invention comprises the following components: a rubber matrix material, a nano TiN, and a vulcanizing agent. According to the present invention, the nano TiN is used as a conductive filler to be applied to the conductive rubber composite material for the first time, and the composite material is used for preparing the conductive rubber sensor, so that application of the nano TiN is broadened, and the obtained conductive rubber sensor has a wider pressure test range, higher linearity, sensitivity and stability, and stronger current signals; a rubber packaging layer is used for packaging a sensing element, so that the sensor is balanced in stress, the phenomenon that the structure is damaged due to stress concentration is avoided, and therefore, the sensor has higher stability and longer fatigue safety life under high load.
