Dipping treatment method for antioxidant graphite
The invention discloses a dipping treatment method for antioxidant graphite. The method includes: cutting the material into a preset size, conducting cleaning with water for 5min, then adopting ultrasonic cleaning for 10min, and performing drying under a temperature condition of 100-110DEG C; weighing aluminum hydroxide and phosphoric acid in a ratio of 1:25, the, and mixing the two, stirring the mixture evenly by a glass rod, then conducting heating on an electric furnace, in a reheating process, adding water and performing stirring constantly to make the mixture in a colorless water state, and conducting heating to boiling; putting the prepared graphite into a well made dipping agent to conduct dipping under a temperature condition of 150DEG C for 30-50min; at the end of dipping, taking out the graphite, drying moisture in a 105DEG C oven, then carrying out heat treatment in a temperature control resistance furnace, and then airing the graphite in a dry container to room temperature. The treated graphite has good oxidation resistance and improved service life.
