Method for Producing an Insulating Material

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for producing an insulating material using plant-based starting material with natural cavities (such as pores). The key steps involve treating this plant material with a water-repelling (hydrophobic) agent, carefully drying it, and then binding it using an aqueous binder. The method also includes creating a foam within the binder or mixture using gas or pore-forming additives to further enhance insulation. The invention emphasizes using parenchymatic plant tissues (like the pith or bark of various plants, e.g., Miscanthus or bamboo), and ensures that only the cavity walls are coated with hydrophobic material, maintaining the natural air pockets while preventing water absorption.

Use CasesContent extracted from patent full text and abstract with AI.

• Thermal and acoustic insulation for buildings (walls, roofs, floors)
• Eco-friendly insulating panels for both new construction and renovations
• Loose-fill or blown-in insulation for attics and cavities
• Spray- or spread-applied insulation for hard-to-reach spaces or surface finishing
• Insulation for prefabricated modular buildings and structures
• Potential use in vehicles, containers, or appliances where sustainable insulation is needed

BenefitsContent extracted from patent full text and abstract with AI.

• Highly sustainable and eco-friendly—uses abundant plant materials and minimal artificial energy for drying
• Excellent water resistance due to hydrophobic treatment, reducing risks of rot and mold
• Maintains insulation performance even in moist environments
• Low energy input compared to conventional insulation materials (e.g., made from plastics or minerals)
• Versatility in application (loose, sprayed, molded panels)
• Potential for local production using regionally available plants, reducing transport and carbon footprint
• Contributes to CO2 sequestration through the cultivation and use of fast-growing plants like Miscanthus
• Avoids future disposal problems associated with synthetic insulating materials

Patent Abstract

The invention relates to a method for producing an insulating material, in which a plant-based starting material comprising natural cavities, especially natural pores, is treated with a hydrophobizing agent, then the treated starting material is dried and the dried hydrophobized starting material is bound with an aqueous binder, wherein the binder prior to the mixing with the hydrophobized dried starting material or else the mixed overall composition composed of binder and hydrophobized starting material is stirred/beaten to a foam by folding in a gaseous fluid and/or a foam is formed by adding a pore former, especially an additive that forms gas bubbles, to the binder prior to the mixing with the hydrophobized dried starting material or else to the mixed overall composition.
