Title (EN) THERMOTHICKENING SIZING FOR ANTIMIGRATION.
(FR) ENSIMAGE PAR UN AGENT S'ÉPAISSISSANT À LA CHALEUR POUR L'ANTIMIGRATION
Abstract:
(EN) The present invention relates to the use of thermothickening polymers in sizing compositions for glass fibre materials in order to inhibit product migration, where the thermothickening polymer is a graft copolymer having a poly(meth)acrγlamide, poly(meth)acrylic acid or a poly((meth)acrylamide-co- (meth)acrylic acid) main chain and grafts pending on the main chain of at least one of the following types: polyoxyethylene, polyoxyethylene-co- polyoxypropylene, poly(N-isopropyKmettOacrγlamide), poly(dimethyl(meth)acrylamide), or poly(N-isopropyl(meth)acrγlamide-co- dimethyl(meth)acrylamide) copolymer. The invention relates to a method of coating glass fibres using sizing compositions containing such thermothickening polymers, specific aqueous sizing compositions themselves, coated glass fibres obtained by such a method of coating, and polymer composite materials obtained using such coated glass fibres.
(FR) La présente invention porte sur l'utilisation de polymères s'épaississant à la chaleur dans des compositions d'ensimage pour des matières en fibre de verre afin d'empêcher la migration de produit, le polymère s'épaississant à la chaleur étant un copolymère greffé comportant une chaîne principale de poly(méth)acrylamide, de poly[acide (méth)acrylique] ou de poly[(méth)acrylamide-co-acide (méth)acrylique] et des groupes greffés pendants sur la chaîne principale d'au moins l'un des types suivants : polyoxyéthylène, polyoxyéthylène-co-polyoxypropylène, poly(N-isopropyl(méth)acrylamide), poly(diméthyl(méth)acrylamide) ou copolymère de poly(N-isopropyl(méth)acrylamide-co-diméthyl(méth)acrylamide). L'invention porte sur un procédé de revêtement de fibres de verre faisant intervenir des compositions d'ensimage contenant de tels polymères s'épaississant à la chaleur, sur les compositions aqueuses d'ensimage spécifiques elles-mêmes, sur des fibres de verre revêtues obtenues par un tel procédé de revêtement et sur des matières composites de polymère obtenues à l'aide de telles fibres de verre revêtues.
