Title (EN) LOW ODOR INSULATION BINDER FROM PHOSPHITE TERMINATED POLYACRYLIC ACID
(FR) LIANT D'ISOLATION PEU ODORANT ISSU D'ACIDE POLYACRYLIQUE A TERMINAISON PHOSPHITE
Abstract:
(EN) A binder composition, obtained by polymerizing acrylic acid monomer in water in the presence of a cure accelerator comprising an alkali metal salt of a phosphorous-containing inorganic acid to form a low molecular weight polyacrylic acid and subsequently reacting said low molecular weight polyacrylic acid with a polyhydroxy crosslinking agent in a crosslinking step to make a composition suitable for use as a component in a binder for fiberglass. A significant improvement involves conducting the crosslinking step in the absence of added catalyst. Moreover, satisfactory results are obtained in the absence of conventional undesirable sulfur odors.
(FR) La présente invention concerne une composition de liant obtenue par la polymérisation de monomère d'acide acrylique dans l'eau en présence d'un accélérateur de durcissement comprenant un sel métallique alcalin d'un acide inorganique contenant du phosphore de façon à former un acide polyacrylique à faible poids moléculaire, puis par la réaction subséquente de cet acide polyacrylique à faible poids moléculaire avec un agent de réticulation polyhydroxy dans une étape de réticulation afin de préparer une composition qui convienne comme composant dans un liant destiné à la fibre de verre. Une amélioration importante consiste à mener l'étape de réticulation sans adjonction de catalyseur. On obtient par ailleurs des résultats satisfaisants sans les odeurs de soufres indésirables classiques.
