Preparation method of heat conduction paster adopting fiber glass mesh as supporting structure

The invention discloses a preparation method of heat conduction paster, adopting a fiber glass mesh as a supporting structure. The preparation method comprises the steps of dissolving and formulating silicon rubber into silicon rubber solution, and sequentially adding vulcanizer, heat conduction filler and a silane coupling agent to formulate size with medium viscosity and fine coating performance by ultrasonic dispersion and ball-milling uniform mixing; and uniformly coating the size on the pretreated glass fiber mesh and obtaining the heat conduction paster through solvent volatilization, drying, moulding curing and trimming. The heat conduction paster has a high heat conduction rate and a small thermal expansion coefficient, is high in heat stability and soft, meets the requirement on an insulating property, and is convenient to use and disassemble since the surface of the paster has certain viscosity that can be adjusted within a certain range.
