The working state of electronic components can be greatly influenced if the redundant heat in the electronic equipment is not conducted out in time, and even the electronic chip can be out of work if the working state is serious, so that the service life is shortened. In order to solve the problem, thermal interface materials are produced, however, the traditional thermal interface materials have low thermal conductivity, which is mainly concentrated on 1-6W/(mK), and it is difficult to meet the high heat conduction requirement of electronic devices.

The present application is only illustrated by the colloid containing the thermally conductive fibers of the embodiment, and the specific composition of the colloid containing the thermally conductive fibers is not limited.
TABLE 1 relevant parameters for steps S1-S6 of examples 5-10.
TABLE 2 relevant parameters for comparative examples 1-8, Steps S1-S6.
TABLE 3 relevant parameters for comparative examples 9-14, Steps S1-S6.
The thermally conductive fiber oriented gel obtained in step S6 of examples 5 to 10 and comparative examples 1 to 14 was tested for thermal conductivity and dielectric constant, the criterion for thermal conductivity was astm d5470, the criterion for dielectric constant was ASTD150, the criterion for temperature resistance range was EN344, the criterion for hardness was ASTD2240, the criterion for tensile strength was ASTD412, the criterion for volume resistance was ASTD257, and the criterion for flame retardancy was UL-94, and the test results were shown in table 4.
Table 4 performance testing of the thermally conductive fiber oriented gel obtained in examples 5-10 and comparative examples 1-14.
As can be seen from tables 1-4, the glue obtained by the automatic orienting and sequencing equipment and method for the heat-conducting fibers in the glue in the examples 5-8 has better performance in all aspects and better heat-conducting stability than the glue obtained by the automatic orienting and sequencing equipment and method for the heat-conducting fibers in the glue in the examples 9-23, namely the pressure of an oil pump device is preferably 5-10MPa, the moving speed V1 of a Y-axis running module is preferably 50-350mm/s, the moving speed V2 of an X-axis running module is preferably 50-350mm/s, and the moving speed V3 of a Z-axis running module is preferably 80-120 mm/s.
This is because the drive division pressure increase can lead to the volume of gluing of binder removal bush to be bigger than normal, though increased out gluey efficiency, the volume of gluing increases and means that the play glue pipe goes out the glue and takes place a small amount of deformations after the fixed container easily for the carbon fiber takes place weak skew in the sequencing of axial (being fibre direction), thereby reduces some heat conduction stability, and the less volume of gluing of drive division pressure can reduce, influences the orientation of carbon fiber in the flow direction, influences the sequencing of carbon fiber in the axial equally. The smaller the moving speed of the X-axis operation module, the Y-axis operation module and the Z-axis operation module is, the larger the glue output is, and the glue body is easy to deform slightly after the glue output from the obtained rubber tube is arranged in a fixed container; the larger the moving speed of the X-axis operation module, the Y-axis operation module and the Z-axis operation module is, the smaller the glue output amount is, although the glue output from the glue output pipe to the fixed container is not easy to deform, the orientation of the carbon fiber in the flow direction is also influenced.
The diameters of the glue inlet and the glue outlet of the comparative examples 1 to 4 are larger than those of the examples 5 to 23, and the comparative examples 1 to 4 compare the diameters of the glue inlet and the glue outlet by increasing the diameters of the glue inlet and the glue outlet, so that the heat conductivity and the dielectric constant of the glue inlet and the glue outlet with increased diameters are poor, because the tapered extrusion flow channel is increased by the glue inlet and the glue outlet with increased diameters, the orientation of carbon fibers in the flow velocity direction is poor, the ordering of the carbon fibers close to the central part of the tapered extrusion flow channel is disordered, and the heat conductivity stability of the obtained colloid product containing the heat-conducting fibers is poor.
The glue dripping speed of the comparative examples 5 to 6 is higher than that of the examples 5 to 10, and although the production efficiency can be improved by increasing the glue dripping speed, the orientation of the carbon fibers in the flow velocity direction is deteriorated due to the excessively high glue dripping speed, the performance of the finally obtained glue containing the heat-conducting fibers in the aspects of heat conductivity and dielectric constant is poor, the performances of other dimensions are not ideal, and the heat-conducting stability of the obtained glue product containing the heat-conducting fibers is poor.
The vertical distances d of comparative examples 7 to 8 are all larger than those of examples 5 to 23, and although the orientation of the carbon fibers in the flow direction becomes good, the colloid is easily deformed after the colloid containing the heat-conducting fibers is discharged to the fixed container through the glue dripping pipe due to the high vertical distance, the influence of self gravity and the inertia influence of the flow rate of the tapered extrusion flow channel, so that the oriented ordering of the heat-conducting fibers in the fiber direction is still maintained after the glue is discharged to the fixed container, and the performances of the obtained colloid containing the heat-conducting fibers are not ideal in all aspects.
The pressure of the driving part of the comparative example 9 is higher than that of the driving parts of the examples 5 to 23, the orientation of the carbon fibers in the flow velocity direction can be faster due to the increase of the pressure, but the problem of too large glue output is also solved, and the glue is easy to deform after the glue is output from the glue output pipe to the fixed container, so that the heat-conducting fibers are difficult to ensure to be still kept in the orientation sequencing in the fiber direction after being output from the glue output pipe to the fixed container, and the performances of the obtained glue containing the heat-conducting fibers are not ideal in all aspects.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
