Abstract

The invention provides water-based phenolic aldehyde epoxy graphene anticorrosion primer and a preparation method thereof. The primer is prepared from a component A and a component B, and the component A comprises water-based epoxy curing agents, titanium dioxide, water-based aluminum paste, carbon black, graphene, nano-barium sulfate, water-based zinc phosphate, iron-titanium powder, dispersing agents, antifoaming agents, foam inhibitors, cosolvent, wetting agents, neutralizer, water-based polyamide wax liquor, flash-rust-proof agents and deionized water; the component B adopts water-based phenolic aldehyde epoxy resin emulsion. The preparation method comprises the steps that the component A is prepared first, and in the using process, the component A and the component B are mixed. According to the anticorrosion primer, due to the fact that the graphene is introduced, the properties of water resistance, acid resistance, alkali resistance, salt tolerance, acetone resistance and salt spray resistance of a coating are greatly promoted; it is indicated that after graphene oxide is introduced into the water-based phenolic aldehyde epoxy graphene anticorrosion primer, the protective property to the coating can be promoted, and the requirements of markets and industries are completely met.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based phenolic epoxy graphene anticorrosion primer and a preparation method thereof. Background technique [0002] At present, about 30% of the steel in the world corrodes every year, and 10% of the steel becomes useless rust, and the annual economic loss due to corrosion is as high as 700 billion US dollars. Metal corrosion has caused direct economic loss and massive waste of resources to modern industry and national economy. Metal corrosion has caused serious damage to modern industry, not only causing serious direct losses, but also causing indirect losses that are difficult to estimate, and even endanger people's lives and property safety. [0003] For a long time, people have been using various technologies to protect metals. The common method is to coat the metal surface with anti-corrosion coatings. The principle is that it shows chemical inertness to corrosive m...
