A review of high

Corrosion is a significant challenge in many practical applications, leading to the deterioration of metal infrastructure and equipment.

In today’s society, with continuous technological advancements and accelerating industrialization, metal materials are widely used in various fields due to their unique physical and chemical properties. the corrosion of metal materials has become a pressing issue, as it not only shortens their lifespan but may also lead to severe safety hazards. effective anti-corrosion treatment of metal materials is critically important. Resins, as novel polymer materials, have become a research focus in the field of metal corrosion prevention due to their excellent performance. This article explores the application and effects of resin modification in metal anti-corrosion.

I. Concept and Importance of Resin Modification

Resin modification refers to the process of altering the molecular structure of resins by adding specific chemical agents or employing special processing techniques, thereby endowing them with new functional characteristics or enhancing their existing properties. In the realm of metal corrosion prevention, resin modification is primarily used to improve adhesion between the resin and the metal substrate, enhance the resin’s corrosion resistance, and increase its temperature resistance.

II. Methods of Resin Modification

1. Surface Treatment Method: Chemically or electrochemically altering the composition of the metal surface to make it more compatible with resin adhesion. For example, forming a protective film on the metal surface through phosphating or chromate treatment increases its affinity with the resin.

2. Filling Method: Adding fillers such as glass fibers or carbon fibers to the resin to strengthen its mechanical properties and heat resistance. These fillers can seal microscopic pores in the resin, preventing corrosive media from penetrating and thus improving corrosion resistance.

3. Crosslinking Method: Creating chemical bonds between resin molecules via chemical reactions to increase crosslinking density, thereby enhancing mechanical performance and corrosion resistance. Common crosslinking agents include unsaturated polyester resins and epoxy resins.

III. Application Cases of Resin Modification in Metal Corrosion Prevention

1. Ship Deck Coatings: Epoxy resin is typically used as the primary film-forming component in ship deck coatings. By adding pigments, fillers, and additives, its corrosion and wear resistance are improved. For instance, coating phosphatized steel surfaces with epoxy resin enhances adhesion and significantly improves corrosion resistance.

2. Automotive Body Coatings: To improve corrosion and wear resistance, automotive coatings often incorporate polyurethane resin systems. Adding nano-fillers like carbon nanotubes or graphene can effectively increase hardness and corrosion resistance.

3. Pipeline Corrosion Protection: In industries such as oil and chemicals, pipelines are frequently exposed to corrosive environments. Using anti-corrosion coatings containing polyimide resins can enhance impermeability and extend pipeline lifespan.

IV. Development Trends in Resin Modification Anti-Corrosion Technology

With the emergence of new materials and technological advancements, resin modification anti-corrosion technology continues to evolve. In the future, more efficient and eco-friendly resin materials, along with advanced technologies like nanotechnology and smart materials, are expected to emerge. These innovations will further improve metal corrosion prevention effects, providing more reliable support for industrial development.

As an highly efficient anti-corrosion method for metals, resin modification holds broad application prospects. By selecting appropriate resin types, adopting suitable modification methods, and continuously innovating anti-corrosion technologies, the corrosion resistance of metal materials can be effectively enhanced, their lifespan extended, maintenance costs reduced, and robust support provided for industrial production.
