Phosphorus-nitrogen flame retardant and brucite powder: environmentally friendly synergistic flame retardant modification of EVA materials

In-depth analysis of the synergistic effect of phosphorus-nitrogen flame retardant and brucite powder in improving the flame retardant properties of EVA materials is conducted, and how this environmentally friendly modification method can meet the dual needs of flame retardancy and environmental protection in modern industry.

With the vigorous development of the plastics industry, flame-retardant modification of polymer materials has become the key to improving their application scope and safety. This article will explore the synergistic flame retardant effect of phosphorus nitrogen flame retardant and brucite powder in ethylene-vinyl acetate copolymer (EVA).

1. Overview of phosphorus-nitrogen flame retardant and brucite powder. As a new type of environmentally friendly flame retardant, phosphorus-nitrogen flame retardant inhibits the spread of flames by forming a protective layer to isolate oxygen and reduce temperature. Brucite powder, as a natural mineral powder, has excellent thermal stability and flame retardant properties.

2. Synergistic flame retardant effect The combined use of phosphorus nitrogen flame retardant and brucite powder produces a significant synergistic effect. This effect not only improves the limiting oxygen index (LOI) of EVA, but also effectively reduces the heat release of the material. rate and smoke production.

3. Performance and environmental advantages This synergistic flame retardant system has minimal impact on the mechanical properties of EVA materials, while maintaining the processing and physical properties of the material. Compared with halogen flame retardants, phosphorus nitrogen flame retardants and brucite powder are more environmentally friendly and do not produce toxic substances.

4. Application prospects The synergistic flame-retardant EVA material of phosphorus nitrogen flame retardant and brucite powder provides a safe and environmentally friendly solution for wire and cable, foam plastics and other applications, and has broad market application prospects.

5. Market and technology development trends The increasing global emphasis on fire safety and environmental protection indicates that the synergistic flame retardant technology of phosphorus-nitrogen flame retardant and brucite powder will usher in wider applications and technological innovation.

The synergistic flame retardant modification method of phosphorus nitrogen flame retardant and brucite powder provides an efficient and environmentally friendly flame retardant solution for EVA materials. This technology not only meets the high standards of material safety required by modern industry, but also meets the growing needs of environmental protection.
