Carbon-carbon composite material adhesive, preparation method and adhesion method
The invention discloses a carbon-carbon composite material adhesive, a preparation method and an adhesion method. The carbon-carbon composite material adhesive is prepared by mixing 25-30% by volume of borosilicate ceramic, 35-50% by volume of carbon powder and 20-35% by volume of formaldehyde solution. The borosilicate ceramic is prepared from organic resin, boron carbide, silicon dioxide, an organic solvent and sodium hydroxide, based on the total volume of the borosilicate ceramic, the borosilicate ceramic comprises the following components in percentage by mass: 15-30% of organic resin, 15-25% of boron carbide, 20-30% of silicon dioxide, 35-45% of organic solvent and 5-10% of sodium hydroxide. The adhesion method comprises the following steps of polishing to-be-bonded surfaces of the two carbon-carbon composite materials, coating a binder, drying in a drying oven, and carrying out high-temperature treatment in a high-temperature vacuum induction furnace. According to the carbon-carbon composite material adhesive and the adhesion method thereof, the bonding surface of the carbon-carbon composite material can reach a certain atom combination, the adhesion strength is ensured, andvarious excellent performances of the carbon-carbon composite material can be basically not influenced.
