Construction material of the application also to the tool pyroelecthc properties of the gained of embodiment 1~5 carries out heat conductivility test.Test knot Fruit is shown in Table 1.
Table 1
From table 1, relative to prior art, the present embodiment 1~5 includes the Building wood of the tool pyroelecthc properties of graphite worm The heat conductivility of material has obtained larger lifting.
It is can be found that with the relevant parameter of embodiment 2 by contrasting above-described embodiment 1:The addition of binding agent, the tool heat The heat conductivility tool of the construction material of electrical characteristics has a certain upgrade.The addition of this explanation binding agent is conducive to graphite worm to be formed Heat conduction network.
It is can be found that with the relevant parameter of embodiment 3 by contrasting above-described embodiment 2:Change the quality percentage of binding agent Than, the factor such as mixing speed, mixing time and drying temperature to the heat conductivility of the construction material of the tool pyroelecthc properties Influence is smaller, and the heat conductivility of the construction material of the tool pyroelecthc properties does not almost occur obvious change.Based on this, we The parameters such as the mass percent of above-mentioned binding agent, mixing speed, mixing time and drying temperature are fixed, by respectively Change density of mass percent, the mass percent of the land plaster and the graphite worm of the graphite worm etc. because Usually study the influence of its construction material heat conductivility to the tool pyroelecthc properties.
Can be learnt by contrasting the embodiment 3 and the embodiment 4:When the density for increasing the graphite worm can To improve the thermal conductivity of the construction material of the tool pyroelecthc properties.
It is can be found that with embodiment 5 by contrasting the embodiment 4:When increase the graphite worm mass percent it Afterwards, the heat conductivility of the construction material of the tool pyroelecthc properties has obtained further raising.
In this manual, in order to detect the capability of electromagnetic shielding of the construction material of the tool pyroelecthc properties, in magnetic field, flat Under the various frequency ranges of face ripple and microwave, tradition is have detected without the construction material of the tool pyroelecthc properties of graphite worm and sheet The shielding attenuation ability of the construction material of the tool pyroelecthc properties of the addition graphite worm that invention is proposed.Wherein, specific data such as table 2 Shown, table 2 is that the correspondence to electromagnetic shielding decay of the construction material of the tool pyroelecthc properties that different materials proportioning is made is closed It is table, wherein the unit of shielding attenuation measured value is dB.
Table 2
From table 2 it can be seen that to the construction material of existing traditional tool pyroelecthc properties without the graphite worm and Speech, after graphite worm is added, can on the whole improve the electromagnetic shielding capability of the construction material of tool pyroelecthc properties, especially There is stronger screening ability for frequency ranges such as plane wave and microwaves.
At the same time, comparative example 1 and embodiment 2 are it is known that the mass percent of binding agent that changes, stirring speed The factor such as degree, mixing time and drying temperature on the capability of electromagnetic shielding influence of the construction material of the tool pyroelecthc properties compared with Small, almost there is no obvious change in the capability of electromagnetic shielding of the construction material of the tool pyroelecthc properties.
Comparative example 2, embodiment 3 and embodiment 4 are as can be seen that when the density of the graphite worm gradually increases When, the construction material of the tool pyroelecthc properties is also gradually increasing the screening ability of magnetic field, plane wave and microwave, illustrates institute The electromagnetic shielding capability for stating the construction material of tool pyroelecthc properties increases with the increase of the graphite worm density.
Comparative example 5, embodiment 6 and embodiment 7 it is known that when the mass fraction of the land plaster is increased, Mass fraction equivalent to the graphite worm in the construction material of the tool pyroelecthc properties declines, the corresponding tool thermoelectricity The construction material of characteristic is also gradually reduced to the screening ability of magnetic field, plane wave and microwave.This described land plaster quality of explanation The increase of fraction be unfavorable for it is described tool pyroelecthc properties construction material electromagnetic shielding, reduce its to magnetic field, plane wave and The electromagnetic shielding capability of microwave.
Compared to prior art, in the construction material of tool pyroelecthc properties of the present invention, using graphite worm, the graphite is compacted The density of worm is smaller, only 0.005g/cm3~0.05g/cm3, specific surface area is big, thus in construction material, it is easier to formed Thermal conductivity network.In the case of with mass ratio identical shared by existing graphite particle, the building of the tool pyroelecthc properties Materials conductive heat-conducting effect is more preferably;In other words, identical heat conduction and shielding can be reached with the graphite worm of smaller scale Effect, while also reducing production cost, tool has an unexpected effect.In addition, the construction material of the tool pyroelecthc properties Remain original mechanical property.The building board being prepared from by the construction material of the tool pyroelecthc properties has excellent leading Hot property.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
