The coating comprises the following components in percentage by weight: 13-15% of epoxy resin, 13-18% of graphene, 1-6% of nano titanium powder, 15-20% of zinc powder, 5-10% of a filler, 1-5% of pigment, 0.1-2% of an additive, 0.1-3% of a dispersing agent, 1-3% of a coupling agent, 5-8% of a curing agent and 24-35% of a mixed solvent. The composite reinforced anticorrosive coating composition containing graphene andnano titanium provided by the invention can improve the corrosion resistance and aging resistance of anticorrosive paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a composite reinforced anti-corrosion coating composition containing graphene and nano-titanium. Background technique [0002] Corrosion causes huge economic losses every year around the world. In order to prevent huge economic losses, the most effective protective measure is to apply anti-corrosion coatings. Anti-corrosion coatings are an indispensable coating in paints and coatings. Under normal conditions, the anti-corrosion coating plays an anti-corrosion effect on the protected object and prolongs the service life of the protected object. The existing anti-corrosion coatings have poor anti-corrosion and anti-aging properties under high temperature. Therefore, there is a need for a composite reinforced anti-corrosion coating composition containing graphene and nano-titanium that can solve the above problems. Contents of the invention [0003] The object of th...
