Summary
This study enhances ethylene-propylene-diene rubber
Area of Science:
- Materials Science
- Polymer Science
- Fire Safety Engineering
Background:
- Ethylene-propylene-diene rubber (EPDM) is widely used but has limitations in thermal and fire resistance.
- Improving the performance of EPDM requires advanced composite structures and modifiers.
- Existing analogs often struggle with balancing density, thermal conductivity, and fire resistance.
Purpose of the Study:
- To investigate the impact of functionally active structures on the properties of EPDM.
- To enhance the physical, mechanical, thermal, and fire-resistant characteristics of EPDM composites.
- To explore synergistic effects between aluminosilicate microspheres, microfibers, and a phosphorus-boron-nitrogen-organic modifier.
Main Methods:
- Formulation of EPDM composites with specific inclusions: aluminosilicate microspheres, microfibers, and a P-B-N organic modifier.
- Evaluation of physical, mechanical, thermal, and fire-resistant properties.
- Analysis of coke and carbonization processes during thermal stress.
- Comparative analysis against existing material analogs.
Main Results:
- Synergistic effects observed between composite components, enhancing heat insulation.
- Increased heating time for unheated sample surfaces by 12-19%.
- Enhanced residual coke formation by 6-17%.
- Microspheres mitigated negative effects of microfibers on density and thermal conductivity.
- Modifier enabled control over coke layer formation.
Conclusions:
- Functionally active structures significantly improve EPDM's thermal and fire-resistant properties.
- The developed composite system offers superior heat insulation and coke formation.
- This research provides a pathway for designing advanced EPDM materials with tailored fire safety characteristics.
