Description
Technical field
What the present invention relates to is a kind of composite piezoelectric material.The present invention also relates to a kind of preparation method of composite piezoelectric material.
Background technology
The highway system of China is just gradually to informationization, technicalization, greenization future development.While the development of attention highway high speed, more to pay attention to the quality of highway and the maintenance service in future, along with road pavement functional requirement and the raising to its long durability evaluation requirements, need to carry out health monitoring to it, but the compatibility on existing sensor and road surface is bad, not only easily makes road surface and sensor cause damage, the healthy state of its inside can not be reflected accurately, such as: fiber-optic grating sensor, capacitance type pressure sensor etc.The power supply of existing online health monitoring systems simultaneously supplies primarily of battery, and is difficult to during runing for the Monitoring systems in road surface or cannot changes power supply.Now in order to provide more lasting continuation of the journey to Monitoring systems, the jumbo battery of general employing or super capacitor, although it can extend the power-on time of Monitoring systems, battery volume can increase a lot, it easily damages under the loading action of vehicle, and makes pavement structure produce destruction.Therefore, in the urgent need to developing a kind of micro power that can be Monitoring systems and power.
Due to the poor compatibility of piezoelectric ceramics and bituminous pavement, easily cause the piezoelectric patches that is embedded in road surface broken on the one hand, easily cause cracking and the destruction on road surface on the other hand.In recent years, piezo-electricity composite material is due to its shaping designability with cost of manufacture is cheap makes it be widely used in the fields such as audio-frequency transducer, electromechanical transducer and underwater transducer.The pressure composite piezoelectric material of asphaltic base is embedded in road surface, when vehicle crosses, is available electric energy by piezo-electric ceramic composite material by changes mechanical energy, can be health monitoring systems and electricity consumption is provided, also can be used as sensor and use.Utilize piezo-electricity composite material, can realize pavement construction machinery can collection, and be converted into micro battery that health monitoring systems powers and utilize its piezoelectric property to realize the preparation of road surface sensor.This novel composite technology has a extensive future.But there is high and that after polarizing, its piezoelectric property is not brought into play the completely problem of polarizing voltage in it.
Because rock asphalt is long-term and physical environment coexists, character is stable especially, has very excellent pavement performance.Rock asphalt uses as a small amount of admixture of properties-correcting agent of artificial refining pitch, forms modifying asphalt, makes it the performance that excellent technical feature reaches maximum.Rock asphalt, as rock asphalt, is a kind of hard pitch of the remote past, generally adds modification use in petroleum pitch or asphalt to as material modified, has good intermiscibility with petroleum pitch.Existing asphalt modifier can be adopted as modified oil pitch such as SBS simultaneously, prepare the pitch of some specified property according to actual needs.
Because polarization is one of critical process preparing piezo-electricity composite material, the piezo-electricity composite material without polarization does not almost have piezoelectricity, after artificial polarization, just have piezoelectricity, and whether polarization fully has influence on material piezoelectric response size.Specific inductivity due to piezoelectric ceramics phase is far longer than the specific inductivity of pitch matrix, even if therefore additional polarizing voltage is very high, piezoelectric ceramic particle still cannot produce higher voltage.Polarizing voltage is too low, and polarization effect is poor, cannot give full play to the piezoelectric property of piezoelectric, and polarizing voltage is too high, likely puncture material cause dielectric loss increase and polarization insufficient.Graphitized carbon black is the excellent material of a kind of electrical property, it not only can improve specific inductivity and the specific conductivity of high molecular polymer and pitch, also solves the problems such as interface compatibility, reduces additional polarizing voltage, reduce operation easier, improve the piezoelectric response of composite piezoelectric material; But need the strict consumption controlling carbon black, too much graphitized carbon black will make the specific conductivity of matrix material increase sharply, and part electric energy is consumed with the form of leakage current and reduces the degree of polarization of pottery.
In " fabrication & properties of carbon black modified PZN-PZT/PVDF piezo-electricity composite material " of the interim publication of " New Chemical Materials " the 35th volume the 12nd, disclose a kind of method being prepared composite piezoelectric material by PZN-PZT piezoelectric ceramic powder, polyvinylidene difluoride (PVDF) (PVDF) and graphitized carbon black.In mass ratio PVDF, graphitized carbon black and PZN-PZT piezoelectric ceramic powder are dispersed in the ethanolic soln of 70 DEG C successively, then continuously stirring in magnetic stirring apparatus, until ethanolic soln all volatilizees complete.Mixed powder is ground and is pressed into the thin slice of diameter 20mm, thickness 1 ~ 2mm, on vulcanizing press at 180 DEG C thermal treatment 10min, obtain piezo-electricity composite material after polishing.Carry out plated electrode process again, put into the silicone oil heated after drying and polarize.Be 5 ~ 10kVmm-1 in polarizing voltage, temperature is the 20min that polarizes at 110 DEG C.
