In modern industry, the performance of materials directly affects product quality and production efficiency. Particularly in fields requiring extremely high wear resistance, impact resistance, and corrosion resistance—such as automotive manufacturing, aerospace, construction, and chemical equipment production—selecting appropriate materials is critical. Modified epoxy resins, as a key class of composite matrix materials, have attracted significant attention due to their excellent comprehensive properties. This article explores the application of modified epoxy resins in wear resistance and analyzes strategies for improving their performance.

1. Basic Characteristics of Modified Epoxy Resins

Modified epoxy resins are high-molecular-weight materials formed by the reaction of an epoxy resin matrix with a curing agent. They exhibit strong adhesion, mechanical strength, and chemical stability. Additionally, their wear resistance, compressive strength, and chemical resistance can be enhanced by incorporating various fillers, pigments, and additives.

2. Analysis of Wear Resistance in Modified Epoxy Resins

Wear resistance is a critical indicator of a material’s ability to resist abrasion. Improving the wear resistance of modified epoxy resins typically involves the following approaches:

(1) Increasing Resin Matrix Hardness Adjusting the molecular structure of the epoxy resin or introducing rigid monomers (e.g., replacing alicyclic epoxy resins with aromatic ones or incorporating siloxane segments via copolymerization) can significantly enhance hardness and wear resistance.

(2) Selecting High-Wear-Resistant Filler Materials Adding hard mineral fillers such as tungsten carbide or boron carbide improves wear resistance. These fillers provide friction-reducing protection during impact, minimizing surface damage.

(3) Incorporating Antiwear Agents Adding antiwear agents like molybdenum disulfide or antimony trisulfide forms a stable lubricating film, reducing the friction coefficient and enhancing wear resistance.

(4) Optimizing Curing Processes Adjusting curing conditions (temperature, humidity, pressure) influences crosslinking density and microstructure. Proper curing promotes uniform, dense structures, improving wear resistance.

3. Practical Applications of Modified Epoxy Resins

Modified epoxy resins have been successfully applied in wear-resistant material development across industries:

• Automotive Manufacturing: Used for engine components and transmission parts, which endure high-speed operation and impact.
• Aerospace: Employed in aircraft engines and airframe structures, where wear and heat resistance are critical.
• Construction: Added to concrete additives and mortars to improve abrasion resistance and impermeability.

Targeted modifications to epoxy resins can substantially improve their wear resistance, extending material lifespan, reducing maintenance costs, and supporting industrial advancements. With ongoing progress in material technologies, future innovations in modified epoxy resins are expected to meet growing industrial demands.
