With the advancement of technology, composite materials have increasingly played vital roles in industrial fields. Among them, epoxy acrylate resin (EAA) and polyvinyl chloride (PVC), as two common plastic materials, are widely utilized due to their unique properties. single materials often struggle to meet the complex and evolving demands of industrial applications. blending modification has become a critical research direction to enhance the comprehensive performance of materials. This paper explores the research progress, applications, and existing challenges of EAA resin and PVC resin blending modification.

I. Principles of EAA Resin and PVC Resin Blending Modification

EAA resin is a thermosetting resin with excellent mechanical properties, electrical insulation, and chemical resistance. it has drawbacks such as high processing temperatures and long curing times. In contrast, PVC resin is a thermoplastic material with good processability and low cost but poor heat resistance, prone to thermal decomposition. By blending these two resins, their advantages can be combined to achieve complementary properties.

II. Applications of EAA Resin and PVC Resin Blending Modification

1. Electronics and Electrical Industry: EAA resin can be used to manufacture circuit boards and housings, while PVC resin is suitable for producing wires and plugs. Blending modification enables performance synergy, improving product reliability and durability.

2. Automotive Manufacturing: EAA resin can be applied to engine components and structural parts, whereas PVC resin is used for tires and seats. Blending enhances strength, wear resistance, and heat resistance while reducing production costs.

3. Construction Industry: EAA resin is employed in windows, doors, and flooring, while PVC resin is used for pipes and decorative panels. Blending improves impact resistance, corrosion resistance, and fire safety, while lowering costs.

III. Challenges in EAA Resin and PVC Resin Blending Modification

1. Compatibility Issues: Due to differences in molecular structure and chemical properties, phase separation may occur during blending, leading to reduced material performance.

2. Processing Performance: The processability of blended materials often declines compared to individual resins, affecting production efficiency and product quality.

3. Environmental Impact: Solvents used in blending processes may pose environmental and health risks, requiring eco-friendly measures.

As an effective method for preparing composite materials, EAA and PVC resin blending modification holds broad application prospects. several challenges remain to be addressed:

1. Optimize blending processes to improve material compatibility;
2. Develop novel additives or compatibilizers to enhance processability;
3. Adopt environmentally friendly solvents or technologies to minimize ecological impact.

EAA and PVC resin blending modification is a valuable technological approach. Through ongoing research and innovation, it has the potential to deliver high-performance composite materials for diverse industries.
