Waterborne epoxy resin mortar has the advantages of convenient construction in humid environments and environmental friendliness,but its mechanical properties are low,and there are almost no practical applications in the protection of harsh impact and wear in hydraulic buildings.A new type of water-based mixed epoxy resin has been prepared,which combines the advantages of water-emulsion epoxy and oil-soluble epoxy.Optimized the design of the anti impact and abrasion water-based epoxy resin mortar ratio,and conducted performance testing.Indoor tests have shown that the adhesive strength on wet surfaces exceeds 3MPa and is not interface failure;The compressive strength of water-based epoxy mortar is higher than 80MPa,which meets the requirements of impact and wear resistance technology.On site tests have also shown that its impact and wear resistance is comparable to that of oil-based epoxy resin mortar,and its overall performance is more excellent.As a result,this new type of water-based epoxy overcome technical bottlenecks,and have the ability to update and replace traditional oil-based mortar.
