Abstract

The invention discloses a preparation method of an anticorrosion coating of stereoscopic-structure graphene-reinforced epoxy resin. The preparation method comprises the steps of (1) weighing the components of epoxy resin, diluent I and graphene powder by mass percent, mixing, and dispersing to obtain graphene epoxy resin liquid; (2) adding a filler, aids and diluent I to obtain graphene epoxy resin color paste; (3) adding mica iron oxide, and mixing to obtain graphene-reinforced epoxy resin anticorrosion coating component A; (4) mixing a curing agent and diluent II, and dispersing to obtain graphene-reinforced epoxy resin anticorrosion coating component B; (5) mixing the graphene-reinforced epoxy resin anticorrosion coating components A and B to obtain the anticorrosion coating of stereoscopic-structure graphene-reinforced epoxy resin. The process of the anticorrosion coating is simple; large-scale production of graphene-based coatings can be achieved; the prepared coating with stereoscopic-structure graphene has good physical properties and evident salt spray resistance.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating of three-dimensional structure graphene reinforced epoxy resin. Background technique [0002] Anti-corrosion coating is a medium that blocks the contact between the surrounding environment and the metal substrate, and can effectively prevent the corrosion of the metal substrate. In recent years, with the continuous strengthening of the development of marine resources, heavy-duty anti-corrosion coatings have become an important research and development direction in the coatings field. [0003] In harsh corrosive environments such as marine and industrial, a three-layer heavy-duty anti-corrosion system is usually used, namely primer, intermediate paint and top coat. The characteristics of each layer of paint film are different, and its role in the system is different. The intermediate paint is connected Primer and topcoat, in the system, act as a barrier and i...
