Abstract The proportion of maintenance and repair costs for underground sewage pipelines within public expenditure continues to increase, which has become one of the huge challenges globally. Coatings are widely recognized as an effective approach to protect pipelines against corrosion. To enhance the volume stability and corrosion resistance of the geopolymer coating, 1% of silane coupling agent, silicone-acrylic emulsion and pure acrylic emulsion were respectively incorporated to prepare organically modified geopolymer corrosion resistant coating. Through basic performance tests, sewage corrosion tests, and microscopic analyses including SEM-EDS, XRD and FTIR, the feasibility of the organically modified geopolymer coating as a corrosion resistant coating for the concrete of sewage pipelines was studied. The results show that compared with the pure geopolymer coating, the adhesive strength of the geopolymer coatings modified by silane coupling agent and styrene-acrylic emulsion increases by 43.8% and 10.9%, the shrinkage rates decrease by 43.8% and 34.3%, the water absorption rates decrease by 28.9% and 35.8%, and the corrosion resistance is enhanced. Conversely, geopolymers modified by pure acrylic emulsions display the opposite properties. The addition of silane coupling agent and silicone-acrylic emulsion refines the pores of the geopolymer. Meanwhile, the silanol groups generated by the hydrolysis of silane coupling agent and silicone-acrylic emulsion are bonded to the hydration products, which improves the compactness of its matrix. The geopolymer coating modified by silane coupling agent and silicone-acrylic emulsion can be applied to the corrosion protection of underground sewage pipelines.

Key words： underground sewage pipeline organically modified geopolymer corrosion resistant coating silane coupling agent silicone-acrylic emulsion pure acrylic emulsion
