Water delivery closed conduit defect repairing process based on acrylic emulsion mortar

The invention relates to the technical field of water delivery closed conduit defect repairing processes, in particular to a water delivery closed conduit defect repairing process based on acrylic emulsion mortar, which comprises the following steps: preparing construction materials such as acrylic emulsion cement mortar, an interface agent and an anti-carbonization protective agent according to the proportion; according to the water delivery closed conduit defect repairing technology based on the acrylic emulsion mortar, the building construction material interface agent and the anti-carbonization protective agent are creatively introduced, the maintenance quality is improved, the concrete interface agent has super-strong bonding force and excellent water resistance and aging resistance, the bonding strength of plastering mortar to a base layer can be improved, and the repairing effect is good. The problems of hollowing, falling, shrinkage cracking and the like of a plastered layer are effectively avoided, t
