NOVELTY - Graphene-type low-viscosity and solvent-free epoxy coating comprises A component and B component. USE - Used as graphene-type low-viscosity and solvent-free epoxy coating. ADVANTAGE - The coating: can be thinly coated with high-hardness, and has super-wear-resistance; can be sprayed with conventional spraying equipment, and the thinnest one-time film thickness can be as low as 50 mum or less; solves the problem of solvent-free epoxy system thin coating, excellent performance, can achieve excellent corrosion resistance effect below 100 mum, and greatly reduce the cost of materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing Graphene-type low-viscosity and solvent-free epoxy coating, comprising (i) preparing graphene modified superhard wear-resistant filler, (ii) preparing modified epoxy resin, (iii) preparing curing agent, the self-made curing agent is made from cardanol, paraformaldehyde and mixed amine through Mannich reaction, the mixed amine is composed of polyetheramine, aromatic amine, aliphatic amine, and tertiary amine in a certain proportion, and the curing agent has the rigidity of aromatic amine and the flexibility of polyetheramine at the same time, (iv) component operation, and (v) after mixing component A and component B according to the mass ratio of 4:1, and curing to obtain graphene-type low-viscosity and solvent-free epoxy coating.
