Description

technical field [0001] The invention relates to the field of coatings, in particular to a stainless steel transparent anticorrosion coating and a preparation method thereof. The transparency of the coating film formed by the stainless steel transparent anti-corrosion coating is above 90%, the bonding force between the coating film and the substrate reaches grade 1, and the coating has a service life of more than 15 years under marine atmospheric conditions, and the coating is non-toxic. Background technique [0002] Stainless steel is a silver-white alloy steel with excellent corrosion resistance, wear resistance, toughness and processing technology. It is widely used in aerospace, ocean, medicine, nuclear energy, petrochemical and other industries. It shows beauty with exquisite natural surface and cleanliness. [0003] The main reason for the increasingly widespread application of stainless steel is based on the characteristics of this series of materials, namely corrosio...
