Problems solved by technology

However, for the preparation of MLCC, the undulating structure on the surface of the polyester film will cause uneven coating after the silicone coating is applied, which will affect the peelability and smoothness of the release film, and will affect the processing of the clay layer. Unfavorable, especially affecting the thickness uniformity of the clay layer

[0041] The preparation method of functional masterbatch of the present invention, comprises the steps:

[0042] At room temperature, add powdered PET with a mass ratio of 90% to 99.5%, nano-graphite at 0.1% to 0.4%, and inorganic filler at 0.1% to 9.9% to a high-speed mixer for pre-dispersion and mixing at a speed of 1000 to 1500rpm. ~30 minutes to form a mixture;

[0043] Raise the twin-screw extruder to the set temperature range according to the table below:

[0044]

[0045] After heat preservation for 2 hours, the aforementioned compound was added from the feeder of the twin-screw extruder for melt extrusion, and then water-cooled and granulated to obtain the functional masterbatch.

[0046] In a specific embodiment, the thermal shrinkage rate (150° C., 30 min) of the functional masterbatch is 0.93% to 0.53% measured after film formation alone.

[0047] It should be noted that the functional masterbatch of the present invention is not a general simple mixing. During t...

Abstract

The present invention proposes a MLCC release film base film and its functional masterbatch and preparation method. In the functional masterbatch of the surface layer of the MLCC release film base film, 90% to 99.5% of PET, 0.1% to 0.4% % of nano-graphite and 0.1% to 9.9% of inorganic fillers. The surface roughness of the MLCC release film base film of the present invention is small and has a smoother surface. Moreover, after the silicone coating is coated on the surface, the repelling effect between the coating and the inorganic filler is significantly reduced at the position where the inorganic filler exists, and the base film with the silicone coating has excellent peelability and smoothness, and can be easily Good to meet the needs of MLCC processing technology.

Description

technical field [0001] The invention relates to a film consumable for manufacturing chip multilayer ceramic capacitors (MLCC) and a preparation method thereof, specifically a release film base film for a chip multilayer capacitor and a functional masterbatch and a preparation method thereof, and at the same time relates to A base film for a release film for a chip multilayer capacitor prepared from the masterbatch. Background technique [0002] Chip multilayer ceramic capacitors (Multi-layer Ceramic Capacitors, abbreviated as MLCC) are laminated by ceramic dielectric diaphragms with printed electrodes (internal electrodes) in a dislocation manner, and form ceramic chips after one-time high-temperature sintering. The metal layer (external electrode) is sealed at both ends of the chip to form a monolithic structure, so it is also called a monolithic capacitor. [0003] With the rapid development of the world's electronics industry, as the basic components of the electronics i...
