摘要： 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.

摘要： 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.
摘要翻译： 本发明提供了可用于生产石膏墙板和其他水性水泥质产品的分散剂和发泡剂组合，形成石膏墙板和石膏墙板的方法。 根据本发明的组合中的分散剂是重均分子量为约17,000至约47,000的萘磺酸 - 醛缩合物碱金属盐聚合物。 碱优选为碱金属和/或碱土金属。 醛优选为甲醛。 根据本发明的组合中使用的发泡剂是皂，优选烷基醚硫酸盐和/或烷基硫酸盐的碱金属盐。 高分子量分散剂和发泡剂的组合产生更有效地夹带空气（即，产生空隙空间）的石膏墙板芯效应，从而降低整体板重量而不会不利地影响强度。 使用根据本发明的分散剂和发泡剂组合形成的石膏墙板与使用常规分散剂和发泡剂以相同的固体负载比形成的石膏墙板相比表现出较高的拔牙力。
