The present invention discloses a kind of manufacturing process for high compactness heat dissipation pad pasting, comprising the following steps: is coated with one layer graphite modified dose in the upper and lower surfaces of Kapton and obtains treated Kapton；The graphite modified dose of group by following parts by weight is grouped as: pyromellitic acid anhydride, benzophenone tetracarboxylic dianhydride, diaminodiphenylmethane, dimethylformamide, N-Methyl pyrrolidone, ethylene glycol, dimethyl silicone polymer；By treated, Kapton is warming up to 1200 DEG C, cooling after heat preservation, to obtain the carbonized film of pre-burned.The present invention improves compactness and crystallinity, further improves heating conduction in the vertical direction and the horizontal direction, the volume contraction for also avoiding fold and being graphitized in sintering process. |
