氟聚合物纳米颗粒涂料组合物
摘要：
一种氟聚合物涂料组合物，含有在结晶性更小或无定形氟树脂的溶剂型溶液中分散的结晶亚微米氟聚合物颗粒的均匀混合物。可以通过共混含有结晶亚微米氟聚合物颗粒的乳胶与含有结晶性更小或无定形氟树脂颗粒的乳胶，凝结并干燥共混的乳胶，并在所述氟树脂颗粒用的溶剂中溶解干燥的共混物，来制备所述组合物。可以通过共混干的结晶亚微米氟聚合物颗粒与a)干的结晶性更小或无定形氟树脂颗粒和所述氟树脂颗粒用的溶剂，或b)结晶性更小或无定形氟树脂的溶剂型溶液，来制备准均匀的组合物。摩擦所述的涂层可以提供在含有结晶亚微米氟聚合物颗粒的结晶性更小或无定形氟树脂粘结剂上的连续或接近连续的氟聚合物表面薄层。
摘要（英）：

A fluoropolymer coating composition contains a homogeneous mixture of crystalline submicron fluoropolymer particles dispersed in a solvent-borne solution of less crystalline or amorphous fluororesin. The composition may be prepared by blending a latex containing crystalline submicron fluoropolymer particles with a latex containing less crystalline or amorphous fluororesin particles, coagulating and drying the blended latices, and dissolving the dried blend in a solvent for the fluororesin particles. Quasi-homogenous compositions may be prepared by blending dry crystalline submicron fluoropolymer particles with a) dry less crystalline or amorphous fluororesin particles and a solvent for the fluororesin particles, or b) a solvent-borne solution of less crystalline or amorphous fluororesin. Rubbing the disclosed coatings can provide a thin, continuous or nearly continuous fluoropolymer surface layer atop a less crystalline or amorphous fluororesin binder containing crystalline submicron fluoropolymer particles.
