Definitions

  • the present invention relates to the so-called “mineral foam” field, namely foams formed from water and surfactants and in contact (usually in intimate mixing) with mineral particles.
  • the invention relates more specifically to the stabilization of this type of foam, including, but not limited to, in the presence of water-repellent constituents.
  • foams that involve contacting them with mineral particles. This is particularly the case when the foam is formed in the presence of mineral particles and especially when it is used to transport such mineral particles (transport of solid during excavations or mining for example).
  • mineral foams are plaster foams or cementitious materials for the preparation of lightened building materials, where it is well known that the presence of mineral particles tends to destabilize the foam.
  • the problem of stabilization is particularly sensitive when it is desired to manufacture water-repellent materials (for the manufacture of plasterboards for bathrooms or kitchens, typically), where the water-repellent agents tend to break the foam.
  • An object of the present invention is to provide a means of forming inorganic foams of the aforementioned type which are stable and typically allow to maintain good integrity of the foam during the shaping and drying operations of plasterboard, preferably including when they include water-repellent agents.
  • At least one first surfactant S1 carrying at least one sulfate group at least one first surfactant S1 carrying at least one sulfate group
  • the subject of the present invention is mineral foams comprising water, mineral particles and the combination of surfactants S1 and S2 mentioned above.
  • the composition may or may not include water-repellent agents.
  • the invention also relates to the uses of these foams, particularly in the field of transport of mineral particles or, more specifically, for the formation of lightened building elements.
  • the subject of the present invention is the use of the abovementioned surfactants S1 and S2 to form a stable foam suitable for contact with mineral particles, in particular plaster particles, with or without water-repellent agents.
  • the first surfactant (S1) is the first surfactant (S1)
  • It is a surfactant bearing at least one sulfate group. Alternatively, it may be a mixture of several (two or more) surfactants of this type.
  • the first surfactant may typically comprise a hydrophobic chain terminated by a sulfate group. It may also be a compound carrying a hydrophobic chain carrying a plurality of sulfate groups. According to one embodiment, the first surfactant S1 may be a polymer, for example a polymer carrying a hydrophobic chain on which are grafted side groups carrying sulfate groups.
  • surfactant S1 can be chosen from:
  • alkyl ether sulphate in particular C8-C18 alkyl ether sulphate, for example C12 and C13 alkyl ether sulphate;
  • alkyl sulphates in particular C8-C18 alkyl sulphates, such as, for example,
  • the surfactant S1 may for example be chosen from the following commercial products, available from Solvay:
  • the second surfactant (S2) is the second surfactant (S2)
  • the second surfactant is typically employed as a co-surfactant, with a mass ration of S2 / S1 typically between 1: 15 and 1: 4, for example between 1:10 and 1: 5.
  • surfactant S2 can be chosen from:
  • the surfactant S2 may for example be chosen from the following commercial products, available from Solvay:
  • a mineral foam formed with the surfactants according to the invention contains water, mineral particles and the mixture of surfactants S1 and S2.
  • the mixture of surfactants S1 and S2 generally represent between 0.01% and 0.05% by weight, for example between 0.02% and 0.03% by weight, typically of the order of 0.02% by weight. relative to the mass of the mineral particles in the dry state, especially when the mineral particles are plaster particles.
  • the mixture of surfactants S1 and S2 typically represents between 5% and 30% by weight, more particularly between 15% and 25% by weight relative to the total weight of surfactants and water.
  • the mineral foam may optionally include other additives.
  • a cationic compound of interest is a polymer or copolymer of DADMAC (diallyldimethylammonium chloride), such as, for example, a vinylpyrrolidone / DADMAC copolymer with a vinylpyrrolidone / DADMAC ratio of typically 70/30 to 90/10, for example of the order of 80 / 20.
  • DADMAC diallyldimethylammonium chloride
  • the three formulations allow a good foam stabilization, with a good maintenance of the volume of the foam, higher than that observed with a standard commercial product (HOSTAPUR ® OSB)
