Embodiment 1

[0014] Prepare by base material and organosilicon masterbatch=3.5:6.5 mass ratio, described base material is PET, i.e. polyethylene terephthalate; Described organosilicon masterbatch is dimethyl dichlorosilane ( CH 3 ) 2 SiCl 2 Mixture with polyethylene terephthalate, in which the content of dimethyldichlorosilane is 7000ppm.

[0015] After the prepared raw materials are mixed and dried, they enter the extruder to melt the raw materials at a temperature of 280 ° C. First, the melted raw materials are filtered through a 5 μm high-precision filter, extruded through a T-shaped die, and cooled on a quenching roller. , after preheating with MDO at 55°C~76°C, 3.65 times longitudinal drawing and 4.1 times TDO transverse drawing are carried out, cooling and crystallization treatment is carried out at the end of TDO transverse drawing, and then semi-finished products are harvested through trimming, winding and other processes , and finally after cutting and packaging, it becomes a 4...

Embodiment 2

[0020] The preparation method is the same as in Example 1, only the base material and the silicone masterbatch are prepared in a mass ratio of 4:6, the base material is PET, that is, polyethylene terephthalate; the silicone masterbatch Dimethyldichlorosilane (CH 3 ) 2 SiCl 2 Mixture with polyethylene terephthalate, in which the content of dimethyldichlorosilane is 7000ppm.

[0021] Slitting the BOPET finished product prepared in this example, the excellent-grade rate of the finished product can reach 91%, and the rate of coated A-grade product can reach 83%.

[0022] The main physical and chemical indicators of the TTR resin-based high-speed coating special-purpose 4.2 micron BOPET finished product measured in this embodiment are shown in the following table:

[0023]

Embodiment 3

[0025] The preparation method is the same as that in Example 1, only the base material and the silicone masterbatch are prepared at a mass ratio of 4.5:5.5, the base material is PET, namely polyethylene terephthalate; the silicone masterbatch Dimethyldichlorosilane (CH 3 ) 2 SiCl 2 Mixture with polyethylene terephthalate, in which the content of dimethyldichlorosilane is 7000ppm.

[0026] Slitting the BOPET finished product prepared in this example, the rate of high-grade finished product can reach 90%, and the rate of coated A-grade product can reach 87%.

[0027] The main physical and chemical indicators of the TTR resin-based high-speed coating special-purpose 4.2 micron BOPET finished product measured in this embodiment are shown in the following table:

Abstract

The invention belongs to the field of BOPET (biaxially stretched polyester film), and in particular relates to a BOPET for TTR resin base. The BOPET product has a thickness of 4.2 microns and is prepared from a base material and a silicone masterbatch; in terms of mass percentage, the base material content is 35% to 65%. Compared with the transitional products used in the prior art, the present invention has greatly improved thermal stability, peelability, cleanliness and surface adaptability to coating solvents, and can better meet the requirements of BOPET for TTR resin-based high-speed coating. performance requirements.

Description

technical field [0001] The invention belongs to the field of BOPET (biaxially stretched polyester film), and in particular relates to a BOPET for TTR resin base. Background technique [0002] At present, the BOPET used in TTR resin-based high-speed coating is generally dedicated to capacitors or a transition product for the production of capacitor-specific BOPET, and there is no 4.2 micron BOPET dedicated to TTR resin-based high-speed coating. The transitional products of BOPET for capacitors, from raw materials to processes, are all aimed at the breakdown resistance and insulation properties of the capacitor film, which cannot meet the thermal stability, peelability, crystallinity, and resistance to coating solvents required for TTR resin-based high-speed coating. Surface adaptability and other properties. Contents of the invention [0003] The purpose of the present invention is to provide a special 4.2 micron BOPET for TTR resin-based high-speed coating. [0004] Tech...
