Ultraviolet aging resistant graphene epoxy resin coating

Abstract

The invention provides an ultraviolet aging resistant graphene epoxy resin coating. The graphene epoxy resin coating is prepared from the following components in percentage by weight: 30 to 50 percentof epoxy resin, 0.2 to 0.8 percent of graphene, 20 to 30 percent of pigment and filler, 0.5 to 2 percent of dispersing agent, 0.5 to 2 percent of anti-foaming agent, 0.5 to 2 percent of leveling agent, 0.5 to 2 percent of anti-settling agent, and the balance of mixed solvent. The ultraviolet aging resistance performance of the graphene epoxy resin coating provided by the invention is more superior to that of an isopropylidenedicyclohexanol A type epoxy resin coating, the salt mist resistance performance of the graphene epoxy resin coating is also obviously higher than that of a common epoxy resin coating and the isopropylidenedicyclohexanol A type epoxy resin coating. Meanwhile, the ultraviolet aging resistant graphene epoxy resin coating provided by the invention also has the advantagesof simpleness and convenience in preparation process, storage stability, and excellent adhesive power, flexibility and abrasion resistance property, and can be applied to outdoor scenes such as high corrosion and high humidity.

Description

technical field [0001] The invention relates to the technical field of industrial coatings, in particular to a graphene epoxy resin coating resistant to ultraviolet aging. Background technique [0002] Since Andre Geim and Konstantin Novoselov of the University of Manchester in the United Kingdom successfully obtained single-layer graphene (graphene) by stripping graphite with tape in 2004, and won the Nobel Prize in Physics in 2010, the electrical conductivity, thermal conductivity, and chemical resistance of graphene have been greatly improved. And other excellent properties are constantly being applied in different fields by the industry. Graphene is mainly a two-dimensional crystal structure composed of sp2 hybrid orbitals arranged in a hexagonal honeycomb. Its thickness is only 0.335nm, which is only the size of a carbon atom diameter. Graphene is currently the thinnest and hardest material. The strength can be a hundred times higher than that of steel, but the specifi...
