Title (EN) AQUEOUS FLUOROPOLYMER DISPERSION
(FR) DISPERSION AQUEUSE DE FLUOROPOLYMERE
(JA) フルオロポリマー水性分散液
Abstract:
(EN) The invention aims at providing an aqueous fluoropolymer dispersion which is suppressed in the viscosity increase due to liquid temperature rise and is therefore excellent in storage stability in spite of its low contents of a fluorinated surfactant and a fluorine-free surfactant. An aqueous fluoropolymer dispersion comprising an aqueous medium containing a fluorine-free surfactant and fluoropolymer particles dispersed therein, characterized in that the amount of the fluoropolymer particles is 35 to 70% by mass based on the dispersion, that the fluorinated surfactant content of the dispersion is 50ppm or below based on the amount of the fluoropolymer in terms of solid matter, that the content of the fluorinine-free surfactant is 1 to 5% by mass based on the amount of the fluoropolymer in terms of solid matter, and that the fluoropolymer is a modified polytetrafluoroethylene.
(FR) L’invention concerne une dispersion aqueuse de fluoropolymère dont la viscosité n’augmente pas lors d’une élévation de la température du liquide, et qui par conséquent fait preuve d’une excellente stabilité de conservation malgré sa faible teneur en tensioactif fluoré et en tensioactif non fluoré. L’invention concerne une dispersion aqueuse de fluoropolymère comprenant un milieu aqueux contenant un tensioactif non fluoré, dans lequel sont dispersées des particules de fluoropolymère, ladite dispersion étant caractérisée en ce que : la quantité de particules de fluoropolymère représente de 35 à 70 % en masse de la dispersion ; la teneur en tensioactif fluoré dans la dispersion est inférieure ou égale à 50 ppm, en se basant sur la quantité de fluoropolymère en termes de matières solides ; la teneur en tensioactif non fluoré représente de 1 à 5 % en masse, en se basant sur la quantité de fluoropolymère en termes de matières solides ; et le fluoropolymère est un polytétrafluoroéthylène modifié.
(JA) 本発明の目的は、含フッ素界面活性剤濃度及びフッ素非含有界面活性剤濃度が低いにもかかわらず液温上昇による粘度上昇を抑え、貯蔵安定性に優れたフルオロポリマー水性分散液を提供することにある。 本発明は、フッ素非含有界面活性剤の存在下に水性媒体中にフルオロポリマーからなる粒子が分散しているフルオロポリマー水性分散液であって、上記フルオロポリマーからなる粒子は、上記フルオロポリマー水性分散液の35~70質量%であり、上記フルオロポリマー水性分散液中における含フッ素界面活性剤は、上記フルオロポリマーの固形分の50ppmに相当する量以下であり、上記フッ素非含有界面活性剤は、上記フルオロポリマーの固形分の1質量%以上、5質量%以下に相当する量であり、上記フルオロポリマーは、変性ポリテトラフルオロエチレンであることを特徴とするフルオロポリマー水性分散液である。
