Abstract

The invention discloses a high-performance graphene-containing water-based acrylate coating. The high-performance graphene-containing water-based acrylate coating contains pure acrylic and/or a styrene-acrylic emulsion, titanium dioxide, calcium carbonate, a dispersing agent, a defoaming agent, a film-forming agent, a flatting agent and sulfonated graphene. The invention further discloses a method for preparing the water-based acrylate coating. Compared with an existing water-based acrylate coating, by adding a minute quantity of sulfonated grapheme into the water-based acrylate coating, the comprehensive properties of the prepared coating are substantially improved, for instance, the tensile strength is increased by 20%-60%, the elongation at break is increased by 25%-70%, the thermal conductivity is increased by 20%-100%, the water resistance is obviously improved, the electrical conductivity is improved by an order of magnitude, and the gas barrier property is increased by 10%-80%. The high-performance graphene-containing water-based acrylate coating is easy to prepare, low in cost and convenient to use and can be applied to the various fields of toughening, heat conduction, corrosion prevention and the like of the water-based acrylate coating.

Description

technical field [0001] The invention relates to a coating and a preparation process thereof, in particular to a graphene-containing high-performance water-based acrylate coating and a preparation method and application thereof. Background technique [0002] Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, and reducing environmental pollution and public nuisance, so it has become the main direction of the current development of the coatings industry. Among them, water-based acrylic acid ester coating is one of the fastest-growing and most diverse non-polluting coatings in water-based coatings. Anti-corrosion coating on metal and non-metal surfaces such as walls, floors, metal products, outdoor advertisements, guardrails, etc. [0003] However, the existing water-based acrylic coatings generally have defects such as low water resistance and weak mechanical properties when they are a...
