A method for producing a fluorine-based grease for an electromagnetic device and a fluorine-based grease for an electromagnetic device manufactured by the method

摘要

The present invention relates to a fluorine-based grease manufacturing method for use on electronic devices: impurities contained in the fluorine oil (1) by receiving fluorine oil (PF) (PFPE-oil, perfluoropolyether) on the heat source device (10). ) Is heated at a temperature of 200 to 250 ° C. in a state of being accommodated on the heat source device 10 so as to be evaporated under reduced pressure through the pressure reducing device 11, and the vacuum of the pressure reducing device 11 communicating with the heat source device 10. Evaporation under reduced pressure by the pump 12 to remove impurities contained in the fluorine oil 1; 10 to 80 wt% of the fluorine resin (2) is mixed on 20 to 90 wt% of the fluorine oil (1) of the reduced pressure evaporation step (S10) to form the mixture (3), and the mixture (3) is stored at room temperature for 1 to 2 days. Ripening step (S20); Stirring step (S30) of stirring the aged mixture (3) of the aging step (S10) in the stirrer (20) for 1 to 3 hours; After homogenizing by stirring the stirred mixture (3) of the stirring step (S30) through a roll mill (30), the manufacturing step (S40) of producing a fluorine-based grease (4) of 265 ~ 295; And a finishing step (S50) of maintaining the fluorine-based grease (4) of the manufacturing step (S40) through a constant temperature at a high temperature and removing foreign matters again (S50). Accordingly, the present invention can significantly reduce the impurities (Nanodust) emitted by the high temperature when using the electronic device to reduce the risk and environmental pollution of the human body, and significantly reduce the wear rate, so that the durability of the product is extended Provides an improved effect.
