The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about to about The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i. e. , creates void space), thereby lowering overall board weight without detrimentally affecting strength.

The present invention provides a sulfonated coal tar distillate salt polymer that is a condensation product of an aldehyde, preferably formaldehyde, and a sulfonated middle fraction obtained during coal tar distillation. The middle fraction includes from about 40% to about 95% by weight naphthalene and from about 5% to about 60% by weight of a plurality of compounds selected from the group consisting of quinoline, indene, biphenyl, indane, acenaphthene, anthracene, phenanthrene, methyl naphthalene, cresol, phenol, xylenol, and tetralin. The present invention also provides a method of forming a sulfonated coal tar distillate salt polymer. The method includes sulfonating the middle fraction to form a middle fraction sulfonic acid mass, optionally adding a first portion of water to the middle fraction sulfonic acid mass to form a mixture, reacting the mixture and an aldehyde to form a condensate, optionally adding a second portion of water to dilute the condensate, and adding a base to form a sulfonated middle fraction salt polymer. Sulfonated middle fraction salt polymers formed in accordance with the method of the invention are useful as dispersants and plasticizers in aqueous cementitious slurries.

A dispersant for use with concrete or cement, and a concrete or cement admixture that comprises a cementitious material, water, and the dispersant. The dispersant includes a polymeric derivative of carboxylic acid, and has a sulfur-containing moiety that is covalently bonded thereto. Adding the dispersant to the cementitious material and water improves the rheological properties of the admixture.

The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i. e. , creates void space), thereby lowering overall board weight without detrimentally affecting strength.

The present invention provides a plaster composition that includes calcined gypsum and a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight from about 17,000 to about 47,000. The present invention also provides a method of forming a plaster composition that includes belending calcined gypsum and a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight from about 17,000 to about 47,000 together to form a dry blend and contacting the dry blend with water to form a hardenable aqueous slurry.

The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength. A gypsum wallboard formed using the dispersant and foaming agent combination according to the invention exhibits a higher nail pull value than gypsum wallboard formed using a conventional dispersant and a foaming agent at the same solids loading ratio.
