Polyvinyl alcohol (PVA), a water-soluble polymer with good biocompatibility, is commonly used as a toughening agent, stabilizer, or crosslinking agent to enhance resin properties. When combined with melamine-modified urea-formaldehyde resin, PVA not only improves the material’s mechanical strength and thermal resistance but also imparts better processability and environmental adaptability to the composite.

In terms of applications, the melamine-modified urea-formaldehyde resin/PVA composite is widely utilized in construction, automotive, electronics, aerospace, and other fields due to its exceptional mechanical, high-temperature resistance, and corrosion-resistant properties. For instance, in construction, it can be employed to manufacture high-strength, durable flooring, ceilings, and furniture; in automotive manufacturing, it is used for body panels and engine components; and in electronics, it serves in circuit boards and casings.

Additionally, the composite exhibits excellent electrical insulation and flame-retardant properties. The melamine functional groups ensure superior electrical insulation, making it suitable for high-voltage equipment and electronic devices. Meanwhile, the incorporation of PVA enhances flame retardancy, offering protective benefits during fire incidents.

To further optimize the composite’s performance, researchers continue to explore new preparation methods and processes. Common techniques include solution mixing, melt blending, and interfacial modification. By adjusting parameters such as resin concentration, temperature, and processing time, fine-tuning of the composite’s properties can be achieved. nanotechnology and surface treatment methods can significantly improve its mechanical strength, thermal stability, and corrosion resistance.
