Abstract

This invention discloses an anti-corrosion coating sintered at low temperature for steel rebars. The composition of coating includes 30-50 weight percent nano-silica, 20-40 weight percent flux, 9-20 weight percent calcium fluoride, 2-10 weight percent thickener, and 2-14 weight percent adhesion, agent. This invention also discloses the coating method of above-mentioned anti-corrosion coating. The method includes seven steps: 1. dry mixing, 2. wet mixing, 3. pretreatment, 4. coating, 5. baking, 6. sintering, 7. cooling down at room temperature. The coating of this invention has high strength, high density, high corrosion resistance, good capacity to bond with concrete, and maintains the mechanical properties of steel rebars.
