Description
Technical field
The present invention relates to rubber composite and preparation method thereof, particularly pressure-sensitive intensity is big, material property is stable, simple, the widely used a kind of pressure-sensitive conductive rubber matrix material of preparation technology and preparation method thereof, belongs to the functional nano composite technology.
Background technology
Along with mechanism develops to structure complicated, often need study, thereby need the slim racking stress transmitter of ideal to carry out contact measurement the interlayer racking stress equal contact stress of complex appts.This novel sensor removes the requirement that should have general strain gauge, outside the performance of suitable precision and sensitivity, better dynamic characteristic, good stable and long work-ing life, also require force sensing element and contact surface material to have the Young's modulus that is complementary, so that reflect real contact situation faithfully, and require the sensing position thin as far as possible, the more important thing is the racking stress measurement requirement that can satisfy non-parallel interface microcell.Because piezoceramic material matter is crisp and the Young's modulus variable range is narrow, obviously can not satisfy this requirement.In recent years, along with the fast development of organic sensitive material, the research of various organic force sensing elements and application make substantial progress, thereby make development non-parallel interface microcell stress measurement become possibility with thin film sensor.
The interlayer contact stress is measured the research with pressure sensitive composite material, at home and abroad all is newer problem.It is reported: the U.S. has developed and has been used for stress measurement pressure sensitive between Automobile air cylinder cap flange layer, but its stable testing remains further to be improved; The domestic ministry of electronics industry 49 is unit such as Fudan University in one's power, also succeeds as yet in the research that the interlayer racking stress is measured aspect pressure sensitive composite material.Pressure transmitter with linear pressure sensitive conductive matrix material, except that having above-mentioned pressure-resistance linear change requires, is also required to have two characteristics: the first, its resistivity will reach 10 at least with the variation of impressed pressure
3Above ability tool practicality; The second, good compression stress relaxation and lower performances such as tension set be arranged.The silicon rubber that the high electricity that is mixed with the 25-35% volume is led metal particle can satisfy the change in resistance requirement, but its processing characteristics and poor mechanical property, the Young's modulus variable range is narrow; Mix the conductive rubber of carbon black or graphite, though its processing characteristics and mechanical property make moderate progress its change in resistance amplitude only 10
2Magnitude is so can't be used as pressure transmitter pressure-sensitive material.The Hussain of the Ding Tianhuai of Tsing-Hua University and Japan is devoted to the research of carbon black/silicon rubber conducing composite material stability and pressure-resistance linear change always, obtained certain achievement, but material is difficult to reach effective Linear Control and stability always.Patent [200710054951.7] adopts silica gel and nickel powder to prepare the pressure sensitive conductive matrix material, but the pressure drag performance repeatability of material is not investigated.
