Abstract

Przedmiotem wynalazku jest folia magnetyczna i sposób wytwarzania folii magnetycznej. Folia magnetyczna składa się z warstwy folii polietylenowej (1), mającej na całej powierzchni regularnie rozmieszczone sześcienne zagłębienia. Warstwa ta jest zgrzana z drugą, płaską warstwą folii polietylenowej (2), wzdłuż wszystkich linii (3), otaczających zagłębienia. Utworzone w ten sposób sześcienne komórki wypełnione są zawiesiną cząstek ferromagnetycznych (4) i ferroelektrycznych (5), w cieczy o wysokiej lepkości (6), korzystnie w oleju cedrowym albo w niespolimeryzowanej żywicy epoksydowej. Cząstki (4, 5) mają rozmiary koloidalne i pokryte są warstewką substancji powierzchniowo-czynnej. Sposób wytwarzania folii magnetycznej polega na tym, że cząstki (4, 5), uzyskane przez mielenie, miesza się ze sobą w stosunku objętościowym 1:1, pokrywa warstwą substancji powierzchniowo czynnej i dodaje do cieczy dyspersyjnej (6), otrzymując zawiesinę, którą wypełnione zostają zagłębienia wytłoczone w folii (1). Następnie zagłębienia te pokrywa się płaską warstwą folii (2) i zgrzewa obie folie ze sobą wzdłuż linii (3), otaczających zagłębienia. Zgrzane, folie (1, 2) oklejane są warstwami folii samoprzylepnej (7, 8).The subject of the invention is a magnetic foil and a method for producing magnetic foil. The magnetic foil consists of a polyethylene film layer (1) having regularly spaced cubic depressions on the entire surface. This layer is welded to the second, flat layer of polyethylene film (2) along all lines (3) surrounding the depressions. The cubic cells formed in this way are filled with a suspension of ferromagnetic (4) and ferroelectric particles (5), in a high viscosity liquid (6), preferably in cedar oil or in unpolymerized epoxy resin. The particles (4, 5) are colloidal in size and are covered with a layer of surfactant. The method of producing the magnetic film consists in the fact that the particles (4, 5) obtained by grinding are mixed together in a 1: 1 volume ratio, covered with a layer of surfactant and added to the dispersion liquid (6), obtaining a slurry filled the recesses are pressed into the foil (1). Then these depressions are covered with a flat film layer (2) and seals both films together along the lines (3) surrounding the depressions. Welded, foils (1, 2) are covered with layers of self-adhesive foil (7, 8).
