Abstract

The invention relates to a preparation method of an ultraviolet-curable nano aluminum phosphate and graphene oxide anticorrosive paint. The ultraviolet-curable nano aluminum phosphate and graphene oxide anticorrosive paint is characterized by comprising a nano aluminum phosphate / graphene oxide composite pigment, epoxy resin, epoxy acrylate and a photoinitiator in a weight ratio of 1-20: 100: 1-30:1-10, the preparation method comprises the following steps: a, loading nano aluminum phosphate with graphene oxide; b, pre-dispersing the composite pigment into epoxy resin; and c, preparing the ultraviolet curable pain according to the formula.

Description

technical field [0001] The invention relates to an ultraviolet curing anti-corrosion coating, in particular to an ultraviolet curing anti-corrosion coating using graphene oxide loaded with aluminum phosphate nanoparticles as an anti-corrosion composite pigment and a preparation method thereof. [0002] technical background [0003] Metal corrosion is the process in which simple metals are oxidized into various metal oxides with different valence states. The loss caused by metal corrosion is very serious, and protection and anti-corrosion treatment must be carried out. Among the various anti-corrosion methods, coating a layer of anti-corrosion paint on the metal surface is a relatively common and effective protection method. Anti-corrosion coatings usually add anti-corrosion pigments to organic resins, and form a protective film on the metal surface to prevent corrosive media from contacting the metal surface to achieve anti-corrosion effects. However, traditional anti-corro...
