Abstract
Compositions include an aerogel component and have low thermal conductivity. Methods for preparing slurries or composites include, for example combining the aerogel component with a surfactant, binder and other ingredients, such as, for instance, fibers. The compositions can be slurries that can be used in coating applications or self supporting rigid composites.
Claims21
A composition comprising:
- a) an aerogel component;
- b) a surfactant;
- c) a binder selected from the group consisting of cement, gypsum, lime, acrylate and any combination thereof;
- and
- d) an ingredient selected from the group consisting of glass fibers, stone fibers, slag fibers, biosoluble ceramic fibers, and any combination thereof, wherein the composition has a thermal conductivity no greater than 50 mW/(m-k), measured according to ASTM C518.
A self-supporting rigid composite comprising an aerogel component in particulate form, a binder selected from the group consisting of cement, gypsum, lime, acrylate and any combination thereof, and at least one other ingredient and having a thermal conductivity no greater than about 20 mW/(m-K), measured according to ASTM C518, wherein the at least one other ingredient includes fibers selected from the group consisting of glass fibers, stone fibers, slag fibers, biosoluble ceramic fibers, and any combination thereof.
A composition comprising:
- a) an aerogel component;
- b) an acrylate in an amount of less than 11%;
- c) a binder or a binder-containing formulation;
- and
- d) at least one other ingredient comprising inorganic fibers, that are mineral wool fibers or a woven, non-woven or chopped form of continuously made glass or stone fiber, wherein the composition has a thermal conductivity no greater than 20 mW/(m-K), measured according to ASTM 0518.
