In technique scheme, further improved plan is as follows:
1. in such scheme, the length of described PE thin film layer and width all exceed 1 ~ 2mm than the length of graphite linings and width.
2. in such scheme, described graphite linings thickness is 20 ~ 100 μ m.
3. in such scheme, described PE thin film layer layer thickness is 50 ~ 65 μ m.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model Antistatic protective film, its ET thin film layer is bonded with PE thin film layer by the second acrylic acid adhesive layer, this PET thin film layer length and width size equates with graphite linings length and width size, this PE thin film layer length and width are all greater than length and the width of graphite linings, described off-style paper layer is covered on another surface of heat-conducting glue adhesion coating, the length of this off-style paper layer and width are greater than respectively length and the width of graphite linings, and PE thin film layer length and width size equates with off-style paper layer length and width size, Graphite Powder 99 and the graphite granule that can prevent graphite linings come off, thereby avoid short circuit and the electrical impact on wiring board, improved the reliability of product, secondly, adopt by aluminium lamination and copper layer by layer stacked group become complex metal layer, be conducive to form the thermograde of ladder, thereby maintain heat conducting impellent, be conducive to that heat is stable to be transmitted fast, again, its laminated polyester film upper surface is coated with antistatic coating, greatly reduces the probability of absorption dust and impurity, thus the heavy losses of effectively having avoided static to cause.
