Abstract
The present invention relates to a process for preparing a particle-stabilized inorganic foam based on calcium sulfoaluminate, to a particle-stabilized inorganic foam based on calcium sulfoaluminate, to a cellular material obtainable by hardening and optionally drying the particle-stabilized inorganic foam based on calcium sulfoaluminate, and to a composition for preparing an inorganic foam formulation for providing a particle-stabilized inorganic foam based on calcium sulfoaluminate.
Claims21
A process for preparing an inorganic foam comprising the steps of
- (1) mixing
- (i) at least one group of inorganic particles;
- (ii) at least one amphiphilic compound;
- (iii) at least one inorganic binder mixture comprising
- (iiia) at least one calcium sulfoaluminate mixture, and optionally
- (iiib) at least one further inorganic binder selected from the group consisting of hydraulic binders, latent hydraulic binders, pozzolanic binders, and mixtures thereof;
- (iv) water;
- and optionally
- (v) at least one additive;
- and
- (2) foaming the resulting foam formulation by chemical, physical or mechanical foaming.
An inorganic foam comprising
- (i) at least one group of inorganic particles;
- (ii) the at least one amphiphilic compound;
- (iii) at least one inorganic binder mixture comprising
- (iiia) at least one calcium sulfoaluminate mixture, and optionally
- (iiib) at least one further inorganic binder selected from the group consisting of hydraulic binders, latent hydraulic binders, pozzolanic binders, and mixtures thereof;
- (iv) water;
- and optionally
- (v) at least one additive.
A composition for preparing an inorganic foam formulation comprising as components
- (i) at least one group of inorganic particles;
- (ii) at least one amphiphilic compound;
- (iii) at least one inorganic binder mixture comprising
- (iiia) at least one calcium sulfoaluminate mixture, and optionally
- (iiib) at least one further inorganic binder selected from the group consisting of hydraulic binders, latent hydraulic binders, pozzolanic binders, and mixtures thereof;
- wherein
- the components (i), (ii), and (iii) are present separately;
- or
- the components (i) and (ii) are present as a mixture and the component (iii) is present separately;
- or
- the components (i), (ii) and (iii) are present as a mixture.
