| As the fluorocarbon resin has excellent weather resistance, heat resistance, stability, and hydrophobic, oleophobic properties, it is currently one of the focuses in coating industry. Adding nano-scale in the paint can greatly enhance the coating corrosion resistance. This combination of the double advantages of fluorocarbon resin and nano-scales help developing a high corrosion resistance of coatings, then property testing was carried out, and the mechanism of the anti-corrosion coating and curing kinetics was explored.By doing a lot of experiments the optimum formula for the anti-corrosion coating was determined: PTFE particle size of 0.5 10μm; binder resin P-200 chosen as the end group-OH, molecular weight of medium B-03 type; mixed solvent composition including N, N-dimethylformamide (10%), N-methyl pyrrolidone (25%), toluene (20%), cyclohexanone (35%), methyl ethyl ketone (5%), acetone (5%) ; PTFE dosage of 8g/100g P-200; titanium nano-scale dosage of 8g/100g P-200.Coating process is divided into low-temperature drying and high temperature sintering in two stages. By DSC experiments and kinetic calculations, optimization process are: drying temperature 25℃100℃, drying time 2030min; sintering temperature 300℃ 340℃, sintering time 20 25min.Adhesion, flexibility level of such coating can achieve Grade 1, impact resistance 80kg, hardness 5H. At 80℃under high temperature accelerated corrosion, anti-corrosion time in ASP solution reached over 600h. In 30% sulfuric acid solution, 30% sodium hydroxide solution, 10% hydrochloric acid, corrosion over time reached 450h; the corrosion current reached the order of 10-8. These data show excellent corrosion resistance.
