Resin curing pipeline repairing air bag and pipeline repairing process thereof

The invention discloses a resin curing pipeline repairing air bag which is used for extending into a pipeline and repairing the pipeline and comprises a heating air bag and a repairing layer. The heating air bag comprises an air bag body, an elastic heating layer wrapping the periphery of the air bag body, metal discs arranged at the two ends of the air bag body and used for fixing the elastic heating layer, and a temperature control device arranged on the metal discs and used for controlling the elastic heating layer. The repairing layer comprises a glass fiber layer wrapping the elastic heating layer and a resin layer smeared outside the glass fiber layer; the air bag body is inflated to enable the elastic heating layer to expand, then the repairing layer is used for being attached to the inner wall of the pipeline, and the temperature control device controls the elastic heating layer to heat so that the repairing layer can form glass fiber reinforced plastic at the stable temperature and is used for repair
