Abstract

A gypsum composition including calcined gypsum, water, and a foaming agent composition which comprises at least one betaine, either alone or in combination with at least one alkyl sulfate and/or at least one alkyl ether sulfate, is disclosed. The gypsum composition can be used to prepare foamed gypsum wallboard.

Claims

AMENDED CLAIMS received by the International Bureau on 07 November 2014 (07.1 1.2014) What is claimed is:
1 . A gypsum composition comprising, in combination with calcined gypsum and water, a foaming agent composition comprising (a) at least one surfactant selected from alkyi sulfates and alkyi ether sulfates, and blends thereof, and (b) at least one betaine.
2. The gypsum composition of claim 1 , wherein the at least one betaine has the following formula I or II:
Ri (R2)2 N+R'COO- or I
O CH3 R3 C - NH(CH2)3 - N+ - CH2COO- II
CH3
where Ri is a C6 to C18 hydrocarbon, R2 is a C1 to C3 alkyi, R' is a C1 to C5 alkyi, hydroxyl alkyi, alkoxylated alkyi, or a combination thereof, and R3 is C6 to C22 hydrocarbon.
3. The gypsum composition of claim 1 wherein the at least one betaine is a mixture of different betaines.
4. The gypsum composition of any one of claims 1 to 3, wherein the foaming agent composition comprises from about 10% to about 90% by weight of the alkyi sulfate, alkyi ether sulfate, or blend thereof, and from about 90% to about 10% by weight of the at least one betaine.
5. The gypsum composition of any one of claims 1 to 3, wherein the foaming agent composition comprises from about 0.01 % to about 99.99% by weight of the alkyi sulfate, alkyl ether sulfate, or blend thereof, and from about 99.99% to about 0.01 % by weight of the at least one betaine.
6. The gypsum composition of claims 4 or 5, wherein the at least one alkyl sulfate has the following formula:
RxOS03 "M+
where R represents a linear or branched chain hydrocarbon, x is between 6 and 16 and M+ is a cation capable of producing a water soluble surfactant.
7. The gypsum composition of claims 4 or 5, wherein the at least one alkyl ether sulfate has the following formula:
Rx(OCH2CH2)yOS03 "M+
where R represents a linear or branched chain hydrocarbon, x is between 6 and 16, y is between 0.01 and 12, and M+ is a cation capable of producing a water soluble surfactant.
8. The gypsum composition of any of claims 4 to 6, wherein the at least one alkyl sulfate is selected from sodium 2-ethyl-hexyl sulfate and sodium decyl sulfate.
9. The gypsum composition of any of claims 1 to 8, wherein the at least one betaine is selected from cocoamidopropyl betaine, capryl/capramidopropyl betaine, and lauramido propyl betaine.
10. The gypsum composition of claims 6 or 7, wherein M+ is selected from the group consisting of sodium, potassium, magnesium, ammonium, and mixtures thereof.
1 1 . A method of producing a foamed gypsum composition comprising:
mixing a foaming agent composition comprising (a) at least one surfactant selected from alkyl sulfates and alkyl ether sulfates, and blends thereof, and (b) at least one betaine, with water and air to generate a foam;
introducing the foam into a calcined gypsum slurry comprising calcined gypsum and water to produce a foamed calcined gypsum slurry.
12. The method of claim 1 1 , wherein the at least one betaine has the following formula I or II:
Ri (R2)2 N+R'COO- or I
O CH3 R3 C - NH(CH2)3 - N+ - CH2COO- II
CH3
where Ri is a C6 to C18 hydrocarbon, R2 is a C1 to C3 alkyl, R' is a C1 to C5 alkyl, hydroxyl alkyl, alkoxylated alkyl, or a combination thereof, and R3 is C6 to C22 hydrocarbon.
13. The method of claim 1 1 , wherein the at least one betaine comprises a mixture of different betaines.
14. The method of any one of claims 1 1 to 13, wherein the foaming agent composition comprises from about 10% to about 90% by weight of the alkyl sulfate, alkyl ether sulfate, or blend thereof, and from about 90% to about 10% by weight of the at least one betaine.
15. The method of any one of claims 1 1 to 13, wherein the foaming agent composition comprises from about 0.01 % to about 99.99% by weight of the alkyl sulfate, alkyl ether sulfate, or blend thereof, and from about 99.99% to about 0.01 % by weight of the at least one betaine.
16. The method of any of claims 1 1 to 15, wherein the at least one alkyl sulfate has the following formula:
RxOS03 M+
where R represents a linear or branched chain hydrocarbon, x is between 6 and 16 and M+ is a cation capable of producing a water soluble surfactant.
17. The method of any of claims 1 1 to 15, wherein the at least one alkyl ether sulfate has the following formula:
Rx(OCH2CH2)yOS03 "M+
where R represents a linear or branched chain hydrocarbon, x is between 6 and 16, y is between 0.01 and 12, and M+ is a cation capable of producing a water soluble surfactant.
18. The method of any of claims 1 1 to 16, wherein the at least one alkyl sulfate is selected from sodium 2-ethyl-hexyl sulfate and sodium decyl sulfate.
19. The method of any of claims 1 1 to 18, wherein the at least one betaine is selected from cocoamidopropyl betaine, capryl/capramidopropyl betaine, and lauramido propyl betaine.
20. The method of claims 16 or 17, wherein M+ is selected from the group consisting of sodium, potassium, magnesium, ammonium, and mixtures thereof.
21 . A gypsum board prepared from the gypsum composition of claim 1 .
22. A gypsum board prepared by the method of claim 1 1 .
