Problems solved by technology

However, due to the high solid content and high viscosity of the currently developed ceramic particle-reinforced polymer coatings, most of them are applied manually, which is often low in efficiency and high in cost, making it difficult to apply on a large scale.

Abstract

The invention discloses a graphene / ceramic particle synergetic modified epoxy resin paint, a preparation method and application thereof. The paint comprises a component A and a component B in a mass ratio of 1-4:1, wherein the component A contains the following ingredients by wt%: 20%-60% of epoxy resin, 30%-50% of silicon carbide particles, 5%-20% of aluminum oxide particles, 1%-5% of a silane coupling agent, 0.5%-5% of graphene and 10%-30% of an epoxy diluent; and the component B includes an epoxy curing agent. During use of the paint, the component A and component B can be mixed evenly andcoated on a treated substrate surface, and after curing, a coating can be obtained. The graphene / ceramic particle synergetic modified epoxy resin paint and the coating thereof have very good erosion resistance and corrosion resistance, can greatly slow down the erosion corrosion of work metal parts under a low stress erosion work condition, prolong the service life, and is especially suitable forthe surfaces of mechanical equipment operating in high humidity, high temperature and high salt fog marine environments suffering serious erosion corrosion.

Description

technical field [0001] The invention relates to a modified epoxy resin coating, in particular to a graphene / ceramic particle synergistically modified epoxy resin coating, its preparation method, and the application of the formed coating on the surface of mechanical equipment operating in a marine environment , belongs to the technical field of anticorrosion material preparation. Background technique [0002] Wear is one of the main forms of failure of mechanical parts. Due to the occurrence of wear and tear in the production process, on the one hand, it will lead to the consumption of a large amount of energy and materials, reducing the operation efficiency and quality of equipment; economic loss. Among them, in material wear, low stress erosion wear accounts for a considerable proportion. Low stress erosion refers to the wear and tear of solid particles impacting the surface of the material and causing material loss and failure. These wear-resistant parts often not only...
