Abstract

The invention belongs to the field of chemical paint and in particular relates to waterborne graphene anticorrosive paint and a preparation method thereof. The waterborne graphene anticorrosive paint is prepared from the following components in parts by weight: polymer waterborne resin, a wet dispersant, a de-foaming agent, a pH (Potential of Hydrogen) regulator, graphene filling slurry, pigment slurry, a flatting agent, a thickener, de-ionized water, a curing agent and an adhesion promoter. The waterborne graphene anticorrosive paint provided by the invention takes water as a diluting agent, does not contain an organic solvent and has no pungent odor so that the waterborne graphene anticorrosive paint does not pollute the environment and has no harms to human bodies. Graphene is added so that the wearing resistance, rigidity and anticorrosive performance of a whole paint surface are improved.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to a water-based graphene anticorrosion coating and a preparation method thereof. Background technique [0002] With the development of low-pollution coating industry and coating process, water-based coatings are rising day by day. The use of water-based coatings reduces the pollution of organic solvents to the environment and ensures the health of operators. Its safe and environmentally friendly production and transportation methods are widely favored. However, the current commercially available water-based anti-corrosion coatings are difficult to compete with solvent-based coatings in terms of anti-corrosion performance, poor water resistance, and salt spray resistance time is less than half of solvent-based coatings, which greatly limits the development of water-based coatings. Contents of the invention [0003] The present invention aims at above-mentioned problem, proposes a...
