Beschreibung
Zusammenfassung:	Sound damping compositions and methods for their application are described herein. The compositions can include a polymer, a polyacrylate rheology modifier, and a polyurethane rheology modifier. The compositions can alternatively include a polymer derived from greater than 80% of one or more monomers selected from the group consisting of butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, methyl acrylate and ethyl acrylate and combinations thereof and greater than 0% and less than 4% of one or more functional monomers, at least one rheology modifier, and a surfactant. Also described herein are sound damping products including the compositions described herein and structures including the sound damping products. Methods for damping sound in a structure are further described herein. The methods include applying the compositions to the surface of a structure and drying the composition. La présente invention concerne des compositions d'amortissement sonore et des procédés pour leur application. Les compositions peuvent comprendre un polymère, un modificateur de rhéologie de polyacrylate, et un modificateur de rhéologie de polyuréthane. Les compositions peuvent en variante comprendre un polymère dérivé de plus de 80 % d'un ou plusieurs monomères choisis dans le groupe constitué de l'acrylate de butyle, l'acrylate de 2-éthylhexyle, le méthacrylate de méthyle, l'acrylate de méthyle et l'acrylate d'éthyle et des combinaisons de ceux-ci et plus de 0 % et moins de 4 % d'un ou plusieurs monomères fonctionnels, au moins un modificateur de rhéologie, et un tensioactif. La présente invention concerne en outre des produits d'amortissement sonore comprenant les compositions présentement décrites et des structures comprenant les produits d'amortissement sonore. La présente invention concerne en outre des procédés pour amortir le son dans une structure. Les procédés comprennent l'application des compositions sur la surface d'une structure et le séchage de la composition.
