More Information
Summary:The invention discloses a repairing method of a composite thermal insulation material, and belongs to the technical field of carbon fiber thermal insulation materials. The method comprises the following specific steps that at the normal temperature, graphite paper bubbling and damaged positions on the surface of the composite thermal insulation material are polished through abrasive paper, dead pixels and the positions 2 cm around the dead pixels are polished to be flat, surface residual chippings are cleaned, a resin solution is brushed, a reinforcing layer is brushed, and the thickness of the reinforcing layer is 1-3 mm higher than the peripheral plane. According to the repairing method, the surface of the composite thermal insulation material is treated for 12-30 hours at the high temperature of 1200-1600 DEG C after being dried at the normal temperature, then the surface of the composite thermal insulation material is ground and polished through flake graphite at the normal temperature, after the composit
