In this paper, the basalt flakes were added to the epoxy coating to In this paper, the basalt flakes were added to the epoxy coating to improve its corrosion resistance. In order to prevent the agglomeration of basalt scale, the mechanochemistry modification process was adopted. The basalt flake was hybrid coated with tetraethyl orthosilicate, hy-311 titanate coupling agent and E-44 epoxy resin. The results showed that the settling time of basalt flakes increased from 2 h to 96 h by hybrid coating. The epoxy coating with 20% hybrid coated basalt flakes has the best performance, the adhesion is 13.40 MPa, and the salt spray resistance time is 2000 h, after immersed in 3.5% NaCl solution for 2000 h, the impedance modulus of 0.01 Hz still has 5.15×109 Ω·cm2.
