Abstract

The invention discloses thin-layer graphene aqueous slurry and a preparation method and application thereof. The thin-layer graphene aqueous slurry comprises the following components in percentage bymass: 1-10% of thin-layer graphene, 1-20% of filler, 0.5-5% of functional auxiliary agent and the balance water. According to the thin-layer graphene aqueous slurry prepared by the preparation method,the graphene is uniformly dispersed in the filler, is stable in storage and good in compatibility with resin and the filler; in the process of mixing with the aqueous resin, emulsion or other fillers, the graphene is difficult to stack and agglomerate due to the blockage of the filler, so that the dispersion effect and efficiency of the thin-layer graphene in a coating is improved, the thin-layergraphene is fully dispersed and spread in the coating, the high-efficiency shielding effect is achieved with low content; and the process is simple, the efficiency is high, and the thin-layer graphene aqueous slurry plays an important role in improving the corrosion resistance of an existing coating based on an aqueous coating.

Description

technical field [0001] The invention relates to a thin-layer graphene water-based slurry mixed with anti-corrosion paint, a preparation method and application thereof, and belongs to the field of nanotechnology and paint. Background technique [0002] With the rapid development of the economy, the use of steel in all walks of life is increasing rapidly, but the corrosion resistance of steel is poor, and protective measures must be taken to prevent corrosion and rust of steel, so as to ensure the safety of steel structures during the design service period. Corrosion of steel has gradually become a problem that everyone has to pay attention to. In my country, the annual corrosion loss is about 2 trillion yuan. Anti-corrosion coatings are one of the most used coatings as protective layers. According to the type of solvent, they are divided into solvent-based, water-based, and solvent-free. Solvent-based anti-corrosion coatings have been the most widely used coatings in the past...
