Embodiment Construction

[0039] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.

[0040] See figure 1 , A phase-change filling and sealing material with built-in graphite fibers, the phase-change filling and sealing material includes the following components by mass percentage: 65% to 80% of thermal conductive particles, 5% to 20% of low melting point solid resin, and 10% to 20% of liquid resin %, coupling agent 0.02% to 2%; the thermally conductive particles include graphite fibers, and the weight of the graphite fibers accounts for 30% to 60% of the total weight of the thermally conductive particles. When the phase change filling and sealing material is lower than the melting point of the low melting point solid resin, it always maintains a solid state; when the phase change material is higher than the melting point of the ...

Abstract

The invention relates to the technical field of materials. A phase change filling sealing material with built-in graphite fibers comprises the following components by mass percent: 65%-80% of thermal conductive particles, 5%-20% of low-melting-point solid resin, 10%-20% of liquid resin and 0.02%-2% of a coupling agent, wherein the thermal conductive particles include graphite fibers, and the weight of the graphite fibers accounts for 30%-60% of the total weight of the thermal conductive particles. When the melting point of the phase change filling sealing material is lower than that of the low-melting-point solid resin, the solid state is kept all the time; when the melting point of the phase change filling sealing material is higher than that of the low-melting-point solid resin, the phase change filling sealing material can be heated to be subjected to phase change to be changed into liquid state or paste state at the temperature, so that the surface of a device can be moistened to a greater degree, contact heat resistance is reduced to be lowest, and a thermal conductive gap filling property of thermal conductive resin or a graphite flake can be acquired.

Description
