Under conditions of 160-180 DEG C, heat treatment 3-4 hours, obtain mixed material；
（2）Step will be added after surplus stock mix homogeneously（1）Mix homogeneously in mixed material after heat treatment, in kneader
Mixing is uniform, processes 2 hours in 120-140 DEG C, obtains blend glue stuff；
（3）Above-mentioned gained blend glue stuff extruded die head is extruded, the thin film after extrusion sequentially passes through chill roll cooling, traction and draws
Stretch, thickness measure, surface corona process, trimming, winding film forming, inspection, put in storage.
As further improvement of these options, the fast basement membrane of the institute evaporation metal coating on basement membrane when in use, metal
The thickness of coating is successively decreased from centre to both sides, and correspondence sheet resistance is 4-60 Ω/ from centre to both sides sheet resistance.
Used as further improvement of these options, the thickness of the basement membrane is 6-8 μm.
The present invention has advantages below compared to existing technology：In the present invention, preparation method is simple, nontoxic, corrosion-free, gained
Basement membrane impact resistance, anti tear, by evaporation metal coating after, with self-healing property it is good, stable performance is good, dielectric strength is high, be difficult to hit
Wear, low production cost the advantages of, while improve the service life of metallic film capacitor, be suitable to promote on a large scale.
