Abstract

The invention discloses an epoxy coating with good heat stability and high adhesive force. The epoxy coating comprises a main material and an auxiliary material, wherein the weight ratio of the main material to the auxiliary material is 10:(3-5). The main material is prepared from, by weight, 10-20 parts of epoxy acrylate resin, 25-40 parts of bisphenol A epoxy resin, 5-8 parts of silicon carbide micropowder, 1-3 parts of mica iron oxide, 3-7 parts of graphene nano-sheets, 5-12 parts of lignin, 4-8 parts of blanc fixe, 5-15 parts of modified hyaluronic acid, 1-2 parts of 3-amino propyl triethoxy silane, 1-3 parts of dispersant and 20-60 parts of water. The auxiliary material is prepared from, by weight, 1.8-2.2 parts of acetic ether, 5-8 parts of diamine methyl cyclohexane, 10-20 parts of cyclohexane and 20-30 parts of water. The epoxy coating has excellent mechanical performance, good corrosion resistance and heat stability and high adhesive force.
