Abstract
(EN)
The present invention provides a method for manufacturing a base material porous film and a laminated porous film having a heat-resistant layer. The method for manufacturing includes: coating the surface of the base material porous film with a coating slurry containing a solvent, a binder resin, and a filler, and subsequently removing the solvent, whereby the heat-resistant layer with the filler as the principal component is formed on the surface of the base material porous film, at which point the contact angle of the coating slurry in relation to the unprocessed base material porous film is adjusted to at least 75°; and furthermore, performing surface processing on the base material porous film before applying the coating slurry to the surface of the base material porous film, so that the contact angle of the coating slurry in relation to the base material porous film is no more than 65°.

La présente invention porte sur un procédé de fabrication d'un film poreux de matériau de base et sur un film poreux stratifié ayant une couche résistant à la chaleur. Le procédé de fabrication comprend : le revêtement de la surface du film poreux de matériau de base avec une suspension de revêtement contenant un solvant, une résine de liant et une charge, puis l'élimination du solvant, ce par quoi la couche résistant à la chaleur, dont la charge est le composant principal, est formée sur la surface du film poreux de matériau de base, auquel point l'angle de contact de la suspension de revêtement par rapport au film poreux de matériau de base non traité est ajusté à au moins 75° ; en outre, l'exécution d'un traitement de surface sur le film poreux de matériau de base avant l'application de la suspension de revêtement sur la surface du film poreux de matériau de base, de telle sorte que l'angle de contact de la suspension de revêtement par rapport au film poreux de matériau de base n'est pas supérieur à 65°.
