Fortifying fibre is: glass fibre, metallic aluminium fiber, carbon fiber.
The present invention also provides the high shaping cycle of a kind of thermal conductivity short PET preparation methods, and its step is as follows:
1, heat conductive filler was dried by the fire 4 hours when 100 spend;
2, heat conductive filler is added in the kneader, add Resins, epoxy, airtight stirring is 1-3 hour under the normal temperature, adds solidifying agent, heats up after the curing, gets material and is broken for little bulk at crusher;
3, the PET pellet is added blender, add auxiliary agent, heat conduction master batch stirring 2min discharging then, after will be behind the material that mixes add in the twin screw extruder master loading hopper, add fortifying fibre at the side spout, the material of extruding is prepared a kind of heat conduction PET through earnestly air-cooled.
Beneficial effect of the present invention is:
