Abstract
Official abstract text for this publication.
The invention relates to a mineral foam stabilised by an association of surfactants comprising: a first surfactant carrying at least one sulfate group; and a second amphoteric surfactant.
First claim
Opening claim text (preview).
1 . A mineral foam containing water, mineral particles, and a combination of surfactants comprising: at least one first surfactant (S1) bearing at least one sulfate group; and at least one second surfactant (S2) that is amphoteric. 2 . The mineral foam as claimed in claim 1 , wherein the mineral particles are particles of plaster. 3 . The mineral foam as claimed in claim 1 , further comprising water-repellent agents. 4 . The mineral foam as claimed in claim 1 , for the transport of said mineral particles. 5 . The mineral foam as claimed in claim 1 , wherein the first surfactant is selected from the group consisting of: alkyl ether sulfates; alkyl sulfates; and mixtures of two or more of these compounds. 6 . The mineral foam as claimed in claim 1 , wherein the first surfactant is selected from the group consisting of: amine oxides; glycinates; sultaines; and mixtures of two or more of these compounds. 7 . A process for forming a stable foam suitable for putting in contact with mineral particles, the process comprising forming the foam with a combination of surfactants comprising: at least one first surfactant (S1) bearing at least one sulfate group; and at least one second surfactant (S2) that is amphoteric. 8 . The mineral foam as claimed in claim 2 , suitable for the formation of lightweight building materials. 9 . The mineral foam as claimed in claim 5 , wherein alkyl ether sulfates are C8-C18 alkyl ether sulfates. 10 . The mineral foam as claimed in claim 9 , wherein C8-C18 alkyl ether sulfates are C12 and C13 alkyl ether sulfates. 11 . The mineral foam as claimed in claim 5 , wherein alkyl sulfates are C8-C18 alkyl sulfates. 12 . The mineral foam as claimed in claim 11 , wherein C8-C18 alkyl sulfates are C12 alkyl sulfates.
