Abstract

The invention discloses an insulating coating of a high-insulating-performance electromagnetic shielding film and a preparation method of the insulating coating, and relates to the technical field of multilayer epoxy resin surface coating treatment and preparation. The film comprises a PET film, the lower side of the PET film is coated with a film layer, and the lower side of the film layer is coated with five epoxy resin layers. Compared with other electromagnetic shielding film insulation layers used at home and abroad in insulation performance, the electromagnetic shielding film insulation layer does not use silicon dioxide at all, reduces the damage of silicon dioxide to the insulation performance, increases rubber and epoxy resin coatings, achieves complete insulation, and is safe and environment-friendly, and five layers of epoxy resin are added on the surface of the insulation layer. And the surface epoxy resin forms a continuous and complete film layer which is firmly combined with the PET original film during drying, so that the strength of the film surface is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of FPC flexible circuit boards, in particular to an insulating coating of an electromagnetic shielding film with high insulating properties and a preparation method thereof. Background technique [0002] The insulating layers of electromagnetic shielding films on the market mainly include epoxy resin, rubber, antioxidants, carbon black, aluminum hydroxide, etc. Because the traditional design requires too much surface roughness to increase the adhesion of the coating, the proportion of silica added is relatively high. , the insulation performance is generally about 10 to the 7th power --- 10 to the 10th power, and it is impossible to achieve complete insulation. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an insulating coating of an electromagnetic shielding film with high insulation performance and a preparation method thereof, so as to solve the technical problem o...
