Context
Traditional materials used in construction, such as wood, plaster, glass wool, or rock wool, offer good mechanical and insulating properties but have disadvantages, including sensitivity to moisture, low recyclability, and health risks associated with volatile fibers.
These materials, although effective for thermal and acoustic insulation, require specific precautions during handling to limit health impacts and avoid the dispersion of constituent elements.
Furthermore, their lack of durability and the presence of toxic substances in their composition highlight the need to develop safer and more sustainable alternatives.
Invention
The invention proposes a new protective and/or combustion material based on cellulosic plant materials and plant-based binding agents that are not chemically modified, offering properties of cohesion, rigidity, thermal insulation, and shock protection, while being ecological, recyclable, and cost-effective. The manufacturing process, which is simple and reproducible, involves mixing and compressing these components at a minimum temperature of 30°C to obtain a homogeneous structure and strong chemical bonds.
Competitive advantages
- Ecology and Sustainability: The material is made from cellulosic plant materials and natural binding agents, not chemically transformed, making it non-toxic, recyclable, biodegradable, and environmentally friendly.
- Mechanical and Insulating Properties: The material combines good rigidity, shock resistance, effective thermal insulation, and homogeneous structural cohesion, meeting the varied requirements of construction, packaging, and protection sectors.
- Cost and Availability: The constituent elements are inexpensive and derived from readily available resources, enabling low-cost production on a large scale.
- Simplified Manufacturing Process: The process is simple, fast, reliable, and reproducible, requiring mixing and compression steps at low temperatures, while ensuring excellent performance of the constituent elements.
