Patent number: 11680019Abstract: A panel has a gypsum matrix, in which the following additives are embedded: glass fibre in an amount greater than 1 wt % relative to the gypsum and a synthetic polymeric binder in an amount greater than 2.5 wt % relative to the gypsum. The glass fibre and synthetic polymeric binder are present in a weight ratio of at least 2 parts binder to one part fibre. The amount of sand present in the gypsum matrix lies in the range 0-0.5 wt % relative to the gypsum. The amount of cellulosic fibre present in the gypsum matrix lies in the range 0-2 wt % relative to the gypsum.Type: GrantFiled: April 6, 2017Date of Patent: June 20, 2023Assignee: Saint-Gobain Placo SASInventors: Nicholas Jones, Adam Richardson, Jan Rideout, Laura Brooks, Joanna Sparkes, David Jalland, Nicola Jupp

Publication number: 20230043281Abstract: Lightweight construction panels, such as gypsum plaster-board, are commonly used to provide internal partitions in buildings It is known to cover, either partially or fully, the panel with an aqueous material such as gypsum plaster or jointing compound. It has been found that known panels expand when they absorb water. This gives rise to several undesirable results such as the gypsum plaster or jointing compound cracking as the panel expands as moisture is absorbed. The present invention provides a panel comprising a gypsum matrix including fibres in an amount of at least 0.8 wt % relative to the gypsum, a polymeric additive in an amount of at least 0.8 wt % relative to the gypsum, and at least one phosphate additive. A panel having such a composition has been found to have desirable characteristics.Type: ApplicationFiled: January 27, 2021Publication date: February 9, 2023Inventors: Jan Rideout, Nicholas Jones, Laura Brooks, Helene Retot, Richard Morlat, Benoit Montigny

Publication number: 20220098858Abstract: A gypsum product has a first polymeric additive and a second polymeric additive distributed therein, wherein the first polymeric additive is a synthetic polymer and the second polymeric additive is starch. It has been found that the combination of starch and a synthetic polymer may result in one or more of the following advantages in the manufacture and performance of gypsum products: increased strength; greater ease of manufacturing due to the increased fluidity of stucco slurries containing both additives; and increased resistance to hygroscopic expansion.Type: ApplicationFiled: October 12, 2021Publication date: March 31, 2022Inventors: Laura Brooks, Nicola Jupp, Joanna Sparkes, Adam Richardson, Nicholas Jones, Jan Rideout

Publication number: 20220009832Abstract: A method of preparing a gypsum-based product comprises the steps of mixing calcined gypsum with polymer particles and water to provide a slurry. The polymer particles comprise principally polyvinyl acetate, and have a particle size distribution, measured using laser diffractometry, such that particles having a diameter of 4.5 ?m or less provide at least 90% of the total particle volume.Type: ApplicationFiled: November 7, 2019Publication date: January 13, 2022Inventors: Kirsty Walton, Nicholas Jones, David Cutler, Nicola Jupp, Laura Brooks
