Patent number: 11884599Abstract: A slurry for manufacturing gypsum board is disclosed. The slurry comprises calcined gypsum, water, a foaming agent, and a thickening agent. The thickening agent of the present disclosure acts to improve the cohesiveness of the slurry without adversely affecting the setting time of the slurry, the paper-to-core bond (wet and dry), or the head of the slurry by acting as a defoaming agent or coalescing agent. Examples of suitable thickening agents include cellulose ether and co-polymers containing varying degrees of polyacrylamide and acrylic acid. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry.Type: GrantFiled: March 11, 2022Date of Patent: January 30, 2024Assignee: Gold Bond Building Products, LLCInventors: Eli Stav, Gopalakrisnan Sethuraman, Ma-Ikay Miatudila, Karen Fey, Joseph J.

Publication number: 20230286864Abstract: Gypsum board having improved performance is obtained by controlling the distribution of starch in the gypsum core of the board and the gelling temperature of the starch. Starch migration in the board is controlled by the degree of acid-modification, to adjust the starch viscosity profile. The starch gelling temperature is controlled by chemical modification of the starch —OH groups.Type: ApplicationFiled: May 22, 2023Publication date: September 14, 2023Inventors: Eli Stav, Ma-Ikay Miatudila
