The vacuum sintering furnace body comprises a sintering furnace main body and a sintering furnace cover. The sintering furnace main body and the sintering furnace cover respectively comprise a steel shell, a heat insulation layer and a molybdenum sheet inner shell which are sequentially stacked from exterior to interior. The vacuum pump is communicated with a vacuum sintering chamber of the sintering furnace main body through a vacuumizing pipeline, a carbon boat is arranged at the bottom of the vacuum sintering chamber, and a workpiece bearing face of the carbon boat is coated with an anti-bonding layer. When the anti-bonding vacuum carbon tube sintering furnace works, the electric heating tube, the vacuum pump and the electromagnetic valve are cooperatively controlled by the master controller to act so as to complete the workpiece sintering operation. The anti-bonding layer is formed by mixing aluminum oxide powder, carbon black and alcohol.
