Surface treatment method of corrosion-resistant high-strength steel bar and concrete thereof

By using a four-arm fluorinated epoxy silane modified epoxy resin coating to form a hydrophobic barrier and self-healing film on the surface of steel bars, the problems of poor compatibility and easy corrosion of epoxy resin coatings with concrete are solved, achieving high adhesion and chemical corrosion resistance.

Abstract

The application discloses a surface treatment method of corrosion-resistant high-strength steel bars and concrete thereof, and the surface treatment method of the corrosion-resistant high-strength steel bars comprises the following steps: uniformly stirring and dispersing four-arm fluorine-containing epoxy silane modified epoxy resin anticorrosive paint for standby; adopting pickling or sand blasting rust removal to the surface of the steel bar to reach Sa2.5 level, removing impurities such as oil stains and dust on the surface of the steel bar, and heating to 40-50 DEG C; coating the standby four-arm fluorine-containing epoxy silane modified epoxy resin anticorrosive paint on the surface of the steel bar, standing, drying and curing, and then the surface treatment of the corrosion-resistant high-strength steel bar is completed; through molecular design, the anticorrosive paint can obtain super-hydrophobic barrier establishment, interface strengthening and self-repairing cooperation, and chemical corrosion resistance is improved.
