Abstract
The present invention relates to a composite material that contains 5 to 97%-vol aerogel particles, at least one binder, and at least one fibre material, the diameter of the aerogel particles being ≧0.5 mm, a process for manufacturing this, and the use thereof.
Claims23
A composite material containing 5 to 97 vol % of hydrophobic aerogel particles, wherein the aerogel particles are SiO2-aerogels and wherein the porosity of the aerogel particles is greater that 60%, their density is lower than 0.4 g/cm3, and their thermal conductivity is less than 40 mW/mK, at least one polymeric or inorganic binder selected from the group consisting of water glass binders, thermoplastic plastics, thermosetting plastics or adhesives, and at least one fiber material, the diameter of the aerogel particles being greater than or equal to 0.5 mm.
A composite material consisting essentially of 5 to 97 vol % of hydrophobic aerogel particles, at least one binder, at least one fiber material, and optionally any one or more of:
- a sizing agent, a coupling agent, an IR opacifier, colouring agents, pigments, extenders, fire retarding agents, synergists for fire protection agents, anti-static agents, stabilizers, softeners, slip agents, and hardening accelerators, wherein the diameter of the aerogel particles is greater than or equal to 0.5 mm.
