Embodiment 1
[0019] Soak 1Kg of commercially available boron nitride micro-nano flakes (diameter 50 microns) in hydrogen peroxide (30wt%), the hydrogen peroxide is submerged in boron nitride, filter after 2 hours, wash the filter cake with water for 3 times, and then dry to obtain hydrogen peroxide treated nitrogen Boron oxide; add 1Kg hydrogen peroxide treated boron nitride, 20g silane coupling agent (2wt%, composed of 10g KH560 and 10g KH550) into the disperser, disperse at 1200rpm for 3 minutes, stop for 1 minute, then disperse at 1200rpm for 3 minutes, stop for 1 minute Minutes, and then disperse at 1200rpm for 3 minutes for surface treatment to obtain surface-treated boron nitride particles; used for the following experiments.
Embodiment 2
[0021] The distribution of large: medium: small is 10%: 30%: 60%, the diameter of the large ball is 3mm, the diameter of the medium ball is 1.5mm, and the diameter of the small ball is 0.5mm; the revolution speed is 240r / min.
[0022] The specific preparation method is as follows:
[0023] Using the dry ball milling method, put the same amount of boron nitride micro-nano flakes into the four ball milling tanks of the planetary ball mill, and select the ball ratio as large: medium: small (10%: 30%: 60%). In principle, the materials, balls, and grinding space each occupy 1 / 3, the speed is selected as 240r / min, forward rotation for 30min, reverse rotation for 30min, cooling for 5min, forward rotation for 30min, reverse rotation for 30min, cooling for 5min, forward rotation for 30min, Inverted for 30 minutes, cooled, and dried to obtain micro-nano boron nitride particles with high thermal conductivity.
Embodiment 3
[0025] The distribution of large: medium: small is 10%: 30%: 60%, the diameter of the large ball is 3mm, the diameter of the medium ball is 1.5mm, and the diameter of the small ball is 0.5mm; the revolution speed is 220r / min.
[0026] The specific preparation method is as follows:
[0027] Using the dry ball milling method, put the same amount of boron nitride micro-nano flakes into the four ball milling tanks of the planetary ball mill, and select the ball ratio as large, medium and small (10%: 30%: 60%). In principle, the materials, balls, and grinding space each occupy 1 / 3, the speed is selected as 220r / min, forward rotation for 30min, reverse rotation for 30min, cooling for 5min, forward rotation for 30min, reverse rotation for 30min, cooling for 5min, forward rotation for 30min, Inverted for 30 minutes, cooled, and dried to obtain micro-nano boron nitride particles with high thermal conductivity.
