Abstract

A method for preparing mechanics sensitive material used on resistance pressure transducer includes using polymer material with elastic modulus of 50 ¿C 500 Mpa as base, placing conductive charge mixture in vacuum dryer for drying 8 ¿C 12 hr. then rising up temperature to 110 ¿C 130deg.c, putting titanate coupling agent as 0.5-3 mass % of conductive charge mixture in said dryer for coupling treatment, placing mixed material on open rubber refining mixer for mixing and pressing it to be flat plate under 135 ¿C 195 deg.c, mould ¿C pressing prepared material to be rectangular samples under 135 ¿C 195 deg.c then cooling it to room temperature for setting on press forming machine.

Description

technical field [0001] The invention belongs to the technical field of manufacturing organic functional materials, and in particular provides a method for preparing a mechanically sensitive material for a resistive pressure sensor. Background technique [0002] The resistive mechanical effect of a material under the action of stress or strain, that is, the pressure-resistance characteristic, reflects the change in resistivity that accompanies the deformation of the material under the action of an external force. Silicon stress sensors, copper-manganese alloy stress sensors and graphite stress sensors developed based on the pressure-resistance characteristics of traditional materials have been used in robotics, aerospace, automotive, biomedical and environmental monitoring and other fields. However, in the process of measuring the extrusion stress of some complex structures with regular and irregular surfaces, the sensor is required not only to have good pressure-resistance c...
