Abstract
The invention provides a metal corrosion-resistant composite material coating and a preparation method thereof. The preparation raw materials of the metal corrosion-resistant composite material coating comprise graphite powder, anhydride, diamine and N-methyl pyrrolidone. The prepared metal corrosion-resistant composite material coating obtained by combining graphene made from the graphite powder with polyetherimide generated by anhydride and diamine is high in viscidity and can be firmly combined with the surface of a metal. The coating is good in toughness, hard to break and high in corrosion resistance, has the remarkable characteristic of effectively preventing metal corrosion, is low in toxicity and has high practicality and application prospect.
