Abstract

The invention relates to an electrostatic conductive and corrosion-resistant epoxy resin-graphene coating and a preparation method thereof. The coating consists of a component A and a component B, wherein the component A comprises the following components in percentage by mass: 24.25 to 26.85 percent of epoxy resin, 0.01 to 3.09 percent of graphene, 0 to 26.24 percent of conductive mica powder, 28.25 to 58.00 percent of a filler, 2.42 to 2.69 percent of a silicon dioxide auxiliary, and a solvent; the component B comprises 50 to 100 percent of a polyamide curing agent and 0 to 50 percent of butanol. The novel composite coating is prepared by utilizing a lamellar structure and high corrosion resistance, electrical conductivity and chemical stability of graphene, has a good electrostatic conduction effect and a good corrosion-resistant effect, and is long in service life, nontoxic and free of pollution. The phenomena of bubbles, cracks, spalling, chalking and digestion after 60-day acid leaching and 60-day alkaline leaching are avoided. A preparation process is simple, and a novel technology for application of graphene to electrostatic conduction and corrosion resistance is provided.

Description

technical field [0001] The present invention relates to a kind of epoxy resin-graphene conductive static anticorrosion coating and preparation method thereof, specifically, the present invention relates to a kind of epoxy conductive static anticorrosion coating based on epoxy conductive anticorrosion coating, and containing graphene epoxy conductive anticorrosion coating and its Preparation. Background technique [0002] With the rapid development of my country's petrochemical industry, the anti-corrosion and safety issues of oil storage tanks have been paid more and more attention by people. As we all know, oil tanks are the main places prone to static electricity accumulation and deflagration accidents. Gasoline, kerosene, diesel and other refined oils will generate static charges through a series of processes such as shearing, friction, impact and collision of pumps, valves and pipelines during the transportation operation. When the generation speed of static charges is ...
