Layer-by-layer self-assembly paper document repairing equipment assisted by vacuum infiltration

The invention discloses layer-by-layer self-assembly paper document repairing equipment assisted by vacuum infiltration. The equipment comprises a spraying system, a self-assembly reaction system, anda vacuum infiltration system. The self-assembly reaction system is a reaction tank. A porous support plate for placing paper to be repaired is horizontally arranged on the reaction tank. The sprayingsystem is arranged above the porous support plate and is used to spray a self-assembly liquor onto the paper. The vacuum infiltration system is connected to a lateral wall, which is arranged under the porous support plate, of the reaction tank. The vacuum infiltration system makes the self-assembly liquor infiltrate the paper to form a film on the paper surface and dries the film. During the self-assembly process, vacuum infiltration is performed to enhance the infiltration of a film forming material on the paper surface; and the process of paper repairing, washing, and drying is greatly shortened. After repairing, th
